Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

An Organic Light Emitting Diode (OLED) display panel has an increasing market share due to its advantages of high sensitivity, high contrast, wide viewing angle, low power consumption, thin and Light weight, and the like.

When the OLED display panel is used as the display panel of the hidden camera scheme, in order to achieve a high transmittance in a high transmittance region on the OLED display panel, the high transmittance region needs to adopt a film material and a driving mode different from those of a non-high transmittance region. For example, the anode and cathode materials used in the high transmittance region are transparent conductive film materials, the non-high transmittance region is made of metal materials, and the transmittance of the transparent conductive film materials is higher than that of the metal materials; the high transmittance region adopts a passive driving mode, the non-high transmittance region adopts an active driving mode, and compared with the active driving mode, the passive driving mode does not need to be provided with a thin film transistor, so that the transmittance is high.

Because the film layer materials and the driving modes (film layer structures) of the high-transmittance region and the non-high-transmittance region are different, the service life of the high-transmittance region is shorter than that of the non-high-transmittance region, and the loss of the high-transmittance region is higher than that of the non-high-transmittance region when the same service time is reached, so that the high-transmittance region and the non-high-transmittance region are not uniform.

It is noted that the high transmittance region can be used to hide other components such as a light sensor (light sensor) besides the front camera.

At least one embodiment of the present disclosure provides a display control method, which applies a display panel, and fig. 1 is a schematic structural diagram of a display panel according to an exemplary embodiment. Referring to fig. 1, the display panel 100 includes a first display area 101 and a second display area 102, the second display area 102 surrounds the first display area 101, and the first display area 101 is disposed near a side of the second display area 102. The transmittance of the first display region 101 is higher than that of the second display region 102, that is, the first display region 101 is the high transmittance region, and the second display region 102 is the non-high transmittance region. Fig. 2 is an application schematic diagram of the display panel in fig. 1, and referring to fig. 2, the display panel 100 is applied in a terminal device 10 (e.g. a mobile terminal), and a front-facing camera or an optical sensor 20 may be disposed in a position corresponding to a first display area 101 in the terminal device 10.

Fig. 3 is a hierarchical structure diagram of the display panel 100. Referring to fig. 3, the display panel 100 includes a substrate 110, an array structure 120 on the substrate 110 (e.g., a glass substrate), an organic light emitting material layer 130, and a cathode layer 140 in this order. Wherein the difference in the life time of the first display region 101 and the second display region 102 may be caused by at least one of a film material and a film structure. For example, the array structure 120 and the cathode layer 140 of the first display region 101 are made of a high transmittance material, and the array structure 120 and the cathode layer 140 of the second display region 102 are made of a general transmittance material, and the high transmittance material has a shorter service life than the general transmittance material. For another example, the array structure 120 of the second display region 102 includes a thin film transistor array and an anode connected to the thin film transistor array, that is, the second display region 102 adopts an active driving manner, and the array structure 120 of the first display region 101 includes only the anode array, that is, the first display region adopts a passive driving manner, so that the service life of the passive driving manner is shorter than that of the active driving manner due to the difference between the film layer structures of the two.

One high transmittance region may be provided on the display panel, or two or more high transmittance regions may be provided.

Fig. 4 is a flowchart illustrating a display control method according to an exemplary embodiment. Referring to fig. 4, the method may be performed by a display panel or a terminal device having the display panel, for example, by a driving circuit in the display panel, which is usually an integrated circuit, or a controller in the terminal device, which is usually an integrated circuit or a processing chip, and the display control method may include:

in step S11, a first display control parameter of the first display area and a second display control parameter of the second display area are determined, respectively.

The first display control parameter is used for indicating the corresponding relation between the gray scale and the first data voltage, and the second display control parameter is used for indicating the corresponding relation between the gray scale and the second data voltage.

Optionally, the first data voltage and the second data voltage corresponding to the same gray scale are different.

Here, the first display control parameter may be a parameter for correcting the high transmittance region, and the second display control parameter may be a parameter for correcting the non-high transmittance region, and the high transmittance region has a shorter service life, so that the aging degree of the high transmittance region is higher than that of the non-high transmittance region in the using process, and the loss of the high transmittance region is higher than that of the non-high transmittance region, and therefore, a larger data voltage is required to achieve the same gray scale effect as that of the non-high transmittance region, that is, the first data voltage corresponding to the same gray scale is different from the second data voltage.

In the embodiment of the present disclosure, the step S11 may be performed periodically, and after the step S11 is completed, the step S12 is performed for the next one period according to the display control parameter. Step S11 may also be performed by event triggering, for example, when the user turns on the display correction function, step S11 is performed.

Optionally, the display control parameter may be a Gamma curve or a display correction coefficient for correcting the Gamma curve used in the first display region. Here, the Gamma curve refers to a correspondence relationship between a data voltage and luminance (gray scale). The Gamma curve used in the first display region is the Gamma curve used in the first display region of the display panel when step S11 is started.

In step S12, the first display area and the second display area of the display panel are controlled to be displayed by the first display control parameter and the second display control parameter, respectively.

The difference between the brightness of the first display area when the first gray scale is displayed by the first data voltage and the brightness of the second display area when the first gray scale is displayed by the second data voltage is a first brightness difference, the difference between the brightness of the first display area when the first gray scale is displayed by the second data voltage and the brightness of the second display area when the first gray scale is displayed by the second data voltage is a second brightness difference, and the first brightness difference is smaller than the second brightness difference.

Wherein the difference between the luminances represents a magnitude of the difference between the luminances. If the luminance of the first display region when the first gray scale is displayed by the first data voltage is the first luminance, and the luminance of the second display region when the first gray scale is displayed by the second data voltage is the second luminance, the difference between the luminance of the first display region and the luminance of the second display region (the first luminance difference) is the absolute value of the difference between the first luminance and the second luminance. If the luminance of the first display region when the first gray scale is displayed by the second data voltage is the third luminance and the luminance of the second display region when the first gray scale is displayed by the second data voltage is the fourth luminance, the difference between the luminance of the first display region and the luminance of the second display region (the second luminance difference) is the absolute value of the difference between the third luminance and the fourth luminance.

For example, when the display control parameter (the first display control parameter or the second display parameter) is a Gamma curve, step S12 may include: and selecting corresponding data voltage from the Gamma curve according to the gray scale value, and controlling the pixel to display by adopting the selected data voltage.

When the display control parameter is the display correction coefficient, step S12 may include: adjusting the Gamma curve used by the first display area by adopting the display correction coefficient; and selecting corresponding data voltage from the adjusted Gamma curve according to the gray scale value, and controlling the pixel to display by adopting the selected data voltage.

In the embodiment of the disclosure, in the display control method, the first display area and the second display area of the display panel are respectively controlled by using the first display control parameter and the second display control parameter, and under the control of the first data voltage and the second data voltage, a luminance difference between the first display area and the second display area is smaller than a luminance difference when the first display area and the second display area are simultaneously controlled by using the second data voltage, so that the display difference between the first display area and the second display area is reduced. For example, the method can compensate for the brightness loss caused by the high loss of the first display region, so that the display difference between the first display region and the second display region is reduced, and the uniformity of the display panel is improved.

Optionally, determining a first display control parameter for the first display region comprises: acquiring display parameters of a first display area, wherein the display parameters comprise: at least one of display duration, brightness corresponding to the binding gray scale voltage, chromaticity corresponding to the binding gray scale voltage, and current corresponding to the binding gray scale voltage; a first display control parameter is determined based on the display parameter of the first display region.

Wherein, at least one means that the display parameters comprise one, two, three or all of the four. For example, in the method, the first display control parameter may be determined only according to the display duration, or the first display control parameter may be determined jointly according to the display duration and the brightness corresponding to the binding gray-scale voltage, which is not limited in this application.

Optionally, the obtaining the display parameter of the first display area, where the display parameter includes luminance corresponding to the binding gray scale voltage or chromaticity corresponding to the binding gray scale voltage, includes:

outputting a display parameter acquisition instruction, wherein the display parameter acquisition instruction is used for indicating a user to place the display panel in an environment with low brightness of ambient light; and acquiring the display parameters of the first display area after receiving a confirmation instruction of the user.

Optionally, the obtaining of the display parameter of the first display area may also be implemented in combination with the above two ways, that is: outputting a display parameter acquisition instruction; when a confirmation instruction of a user is received, acquiring ambient light information; and when the brightness of the ambient light is smaller than a first threshold value, acquiring the display parameters of the first display area.

Optionally, the determining the first display control parameter based on the display parameter of the first display area includes:

and determining the Gamma curve corresponding to the display parameter range where the display parameters of the first display area are located based on the corresponding relation between the display parameter range and the Gamma curve.

and determining a display correction coefficient corresponding to the display parameter range in which the display parameters of the first display area are located based on the corresponding relation between the display parameter range and the display correction coefficient, wherein the display correction coefficient is used for correcting the initial Gamma curve.

In this implementation manner, two methods for determining display control parameters based on the display parameters of the first display area are provided, one is to directly determine a Gamma curve, and the other is to obtain a coefficient for adjusting the Gamma curve used in the first display area, and both the two methods can obtain a new Gamma curve suitable for the current display panel, thereby ensuring display uniformity.

Optionally, determining the first display control parameter based on the display parameter of the first display area comprises: comparing the difference between the display parameters of the first display area and the reference display parameters; when the difference exceeds a second threshold, a first display control parameter is determined.

The reference display parameter may be a display parameter of the second display area, or may be a display parameter of the first display area before a period of time.

Optionally, determining the first display control parameter based on the display parameter of the first display area comprises: acquiring a difference value between the display parameters of the first display area and the display parameters of the second display area; when the difference exceeds a threshold, a first display control parameter is determined.

Optionally, determining the first display control parameter based on the display parameter of the first display area comprises: the method comprises the steps of acquiring the variation of a display parameter of a first display area in a first designated time period, and determining a first display control parameter when the variation exceeds a threshold value.

Alternatively, when determining the first display control parameter, in addition to the change of the display parameter of the first display region, the change of the display parameter of the second display region may be considered. For example, determining the first display control parameter based on the display parameter of the first display region comprises: the method comprises the steps of obtaining a first variable quantity of display parameters of a first display area in a second appointed time period and a second variable quantity of the display parameters of a second display area in the second appointed time period, and determining a first display control parameter when the difference between the first variable quantity and the second variable quantity exceeds a preset difference value.

Optionally, the first display control parameter and the second display control parameter each include a display control parameter corresponding to each color channel.

Optionally, performing display correction on the display panel by using the first display control parameter includes:

acquiring the gray scale of each sub-pixel positioned in a first display area and the gray scale of each sub-pixel positioned in a second display area in a target picture;

determining the data voltage of each sub-pixel of the first display area of the display panel based on the first display control parameter and the gray scale of each sub-pixel positioned in the first display area; determining the data voltage of each sub-pixel in the second display area of the display panel based on the second display control parameter and the gray scale of each sub-pixel in the second display area;

It should be noted that the foregoing steps S11-S12 may be combined with the foregoing optional steps and the foregoing optional steps.

It should be noted that the display characteristics of the second display region may be corrected in a manner similar to the above-described manner of correcting the first display region. This disclosure will not be repeated here.

Fig. 5 is a flowchart illustrating a display control method according to an exemplary embodiment. Referring to fig. 5, the method may be performed by a display panel or a terminal device having the display panel, for example, by a driving circuit in the display panel, which is usually an integrated circuit, or a controller in the terminal device, which is usually an integrated circuit or a processing chip, and the display control method may include:

in step S21, the display parameters of the first display region are acquired.

Optionally, the display parameters include: at least one of display duration of the first display region, brightness corresponding to the binding gray scale voltage, chromaticity corresponding to the binding gray scale voltage, and current corresponding to the binding gray scale voltage. Chroma refers to the saturation of a color.

In the implementation mode, the display condition of the current first display area can be accurately determined through information such as brightness, chromaticity, current and the like, so that display correction is carried out according to the display condition; and as the display duration increases, the display effect of the first display area is poorer, so that the display control parameter can be determined according to the length of the display duration.

The display duration is the accumulated display time of the display panel, and the accumulated display time is usually recorded by a controller of the display panel or a controller of the mobile terminal, for example, a counter or a timer in the controller may be used to record the accumulated display time of the display panel, when the display panel is powered on and works, the counter or the timer works, and when the display panel is ready to be powered off and stops working, the recording result is stored. Therefore, when the display parameter includes the display duration, step S21 may include: and acquiring the display duration recorded by the controller of the display panel or the controller of the mobile terminal.

The tie gray levels are generally gray levels stored in a Gamma curve in a driving circuit of the display panel, and although the Gamma curve corresponds to data voltages of each gray level, in order to reduce a storage space, data voltages of only a few tie gray levels, for example, 8 tie gray levels, are stored in the driving circuit, and data voltages of other gray levels can be calculated according to the voltages. The binding gray scale voltage is also the data voltage of the binding gray scale. The tie point is a key point selected from the gray levels of 0 to 255, for example, 31, 63, 95, 127, 159, 191, 223, 255, and the driver circuit or the controller can calculate data of any gray level based on data of the key point.

Further, when the display parameters such as the luminance corresponding to the tie point gray scale voltage, the chromaticity corresponding to the tie point gray scale voltage, and the current corresponding to the tie point gray scale voltage are acquired, the display parameters may be acquired when the monochrome picture is displayed in the first display region, or may be acquired when the multicolor picture is displayed in the first display region. The monochrome picture refers to a red, green or blue picture, and the multicolor picture refers to a pure color picture obtained by combining at least two of three monochrome colors, such as a white picture.

The method comprises the steps of obtaining display parameters corresponding to binding gray scales when a monochrome picture is displayed, for example, obtaining display parameters corresponding to the binding gray scales when blue light is displayed, wherein at the moment, a red sub-pixel and a green sub-pixel in each pixel are both 0 gray scales, and a blue sub-pixel is not 0 gray scale, so that monochrome-blue is displayed, and then detecting the display parameters. In the method of acquiring display parameters corresponding to the binding point gray scale when displaying a monochrome picture, different monochrome colors may be sequentially displayed, and then display parameters, such as red, green, and blue colors, may be respectively acquired.

When the multi-color picture is displayed, the display parameters corresponding to the binding gray scale are obtained, for example, when the white light is displayed, the display parameters corresponding to the binding gray scale are obtained, at this time, each color sub-pixel in the first display area adopts the same gray scale to display the white light, and then the display parameters are detected.

When the display parameter of the first display area is detected, the second display area may not be displayed, thereby reducing interference with the display parameter of the first display area.

The luminance or the chromaticity may be detected by a photodetection device disposed opposite to the first display region of the display panel and far away from the display surface of the display panel, where the display surface refers to a surface from which light is simultaneously emitted from the first display region and the second display region of the display panel, that is, a surface of the display panel disposed on the terminal device facing outward (user). The photoelectric detection device comprises at least one of a camera and a light sensor, for example, an electric signal output by the camera or the light sensor is acquired, and the electric signal is converted into at least one of chromaticity and brightness.

It should be noted that, before the camera is used to collect the luminance or chrominance information of the first display area, the method may further include: the camera is calibrated for brightness or chromaticity, and the calibration process is usually finished at the time of factory shipment. When the light sensor is used for collecting the brightness or chromaticity information of the first display area, the light sensor has the capability of deducting the influence of ambient light on the collected information, and the capability can be realized through an algorithm obtained by detection in advance.

In one implementation manner of the embodiment of the present disclosure, when the display parameter includes luminance corresponding to the binding gray scale voltage or chromaticity corresponding to the binding gray scale voltage, the step S21 may include:

In the implementation mode, two implementation modes for acquiring the display parameters are provided, the first mode is an automatic acquisition mode, the second mode is a manual acquisition mode, and the acquisition of the display parameters can be realized through the two modes, so that a basis is provided for subsequent display correction. Since the transmittance of the first display region is high, in order to avoid interference of the display parameters by the external ambient light, it is necessary to acquire the display parameters in an environment where there is no ambient light or the ambient light is small, for example, at night or in a dark place.

When the display parameter includes a binding gray scale voltage, step S21 may include: the voltage of a detection resistor in a drive circuit of the first display region is acquired, and the current is determined according to the voltage of the detection resistor. Since the first display region and the second display region are separately wired, the detection resistor may be a resistor (e.g., a resistor provided on a flexible circuit board) provided in a driving circuit of the first display region, through which current detection can be achieved. Here, the number of the detection resistors may be one or more.

In step S22, the difference between the display parameter of the first display region and the reference display parameter is compared. When the difference exceeds the second threshold, step S23 is executed.

And when the difference value does not exceed the second threshold value, exiting the current process. In this case, the first display control parameter in the first display region is the same as the second display control parameter in the second display region, and the display panel is just put into use.

The reference display parameter may be a set of luminance, chrominance or current detected in advance and stored in the display panel or the mobile terminal. The reference display parameter may also be detected in real time, for example, when a current is used as the display parameter, the reference display parameter may be a current value of the same gray scale of the second display region detected in real time. The reference display parameter may also be a fixed value, for example, when the display duration is adopted as the display parameter, the reference display parameter may be 0.

In step S23, a first display control parameter is determined based on the display parameter of the first display region.

Optionally, the determining the first display control parameter is one of a plurality of Gamma curves, the plurality of Gamma curves are stored in a driving circuit of the display panel, the plurality of Gamma curves respectively correspond to a plurality of different stages, the different stages are represented by different display parameter ranges, and the determining the first display control parameter based on the display parameter of the first display area includes:

For example, different display stages are represented by different luminance ranges, such as a luminance range from a1 to a2 in the first stage, a luminance range from a2 to A3 in the second stage, and so on, wherein a1, a2 and A3 are gradually reduced.

In different Gamma curves, at least part of gray scales correspond to different data voltages. For the display parameters such as brightness, chromaticity, current, etc., the smaller the range of the display parameters is, the larger the data voltage corresponding to the same gray scale in the corresponding Gamma curve is. For time, the larger the display parameter range is, the larger the data voltage corresponding to the same gray scale in the corresponding Gamma curve is.

Further, the method may further include: and acquiring the corresponding relation between the display parameter range and the Gamma curve or the corresponding relation between the display parameter range and the display correction coefficient. The process of obtaining the above correspondence relationship may be obtained by a life test.

Fig. 6 is a schematic diagram of Gamma curves at different stages according to an embodiment of the disclosure, where, referring to fig. 6, a curve 1 is an initial Gamma curve, and a curve 2 is a Gamma curve after being used for a period of time, and a Data voltage required for the same brightness increases with time. And the display correction of the first display area can be realized by adopting different Gamma curves at different time.

In the embodiment of the present disclosure, the correspondence between the display parameter range and the display correction coefficient mentioned in the second mode may be stored in the controller of the display panel or the controller of the mobile terminal in advance, or may be generated in real time by the controller of the display panel or the controller of the mobile terminal. For example, the data voltage of the binding point gray scale of the first display area of several stages or the fitting function of the change of the brightness, the chromaticity or the current of the first display area is stored in advance, the fitting function of the change of the brightness, the chromaticity or the current is the fitting function of the change of the brightness, the chromaticity or the current along with the display duration, and the corresponding relation between the display parameter range and the display correction coefficient is determined based on the data voltage of the binding point gray scale of the first display area of several stages or the fitting function of the change of the brightness, the chromaticity or the current of the first display area.

The corresponding relationship between the display parameter range and the display correction coefficient is determined based on the luminance, chromaticity or current variation fitting function of the first display area, and the display correction coefficient may be determined based on the luminance, chromaticity or current variation fitting function of the first display area and the relationship between the luminance, chromaticity or current and the data voltage. Here, the relationship between luminance, chromaticity, or current and data voltage is known in advance. For example, if the luminance is proportional to the voltage to the power of N, which is the Gamma value, then based on this relationship, a display correction factor may be determined. For example, Y ═ X in the initial Gamma curve^2.2Z ═ X in a Gamma curve after a period of time^2.2×nX is the data voltage, Y, Z is the brightness, and n is the display correction factor. Based on the brightness change fitting function, the initial brightness Y and the current brightness Z can be determined, and the value of n can be determined based on the formula, so that the corresponding relation between the display parameter range and the display correction coefficient is obtained.

For the method of determining the corresponding relationship between the display parameter range and the display correction coefficient based on the data voltage of the binding point gray scale of the first display area in the plurality of stages, the display correction coefficient may be determined according to the relationship between the luminance, the chromaticity, or the current and the data voltage, and the corresponding relationship between the display parameter range and the display correction coefficient may be obtained.

Fig. 7 is a graph of a luminance change fitting function shown in an embodiment of the present disclosure. In fig. 7, the horizontal axis represents time, the vertical axis represents the luminance of the first display region, and the luminance of the first display region in fig. 7 is generated by the data voltage of the same binding point gray scale, and referring to fig. 7, three lines respectively represent the luminance when displaying monochrome images of red, green, and blue, and it can be seen that the luminance of any color image gradually decreases with time. It should be noted that fig. 7 shows a curve of a fitting function of the luminance of light emitted by three different color sub-pixels under the same gray scale voltage, and it can be seen that the attenuation degrees of the different color sub-pixels are different.

In the embodiment of the present disclosure, the steps S21-S23 may be performed periodically, for example, once every 30 days, and after the step S23 is completed, the display panel only needs to acquire the first display control parameter to control the first display area to display in the next period of time. The steps S21-S23 may be executed non-periodically, for example, in conjunction with fig. 7, when the luminance (or chromaticity) of a certain color decreases by a fixed value under the action of a data voltage of a certain binding point gray scale, the steps S21-S23 are executed once to obtain a first display control parameter, and then the display panel only needs to obtain the first display control parameter to control the first display area to display. Among them, step S22 is an optional step. The steps S21-S23 may also be executed by event triggering, for example, when the user turns on the display correction function, the steps S21-S23 are executed to obtain the first display control parameter, and then the display panel only needs to obtain the first display control parameter to control the first display area to display.

When the display panel displays each picture, in addition to acquiring the first display control parameter, the display panel also needs to acquire a second display control parameter, and the second display control parameter may be determined in advance or may be a fixed parameter. For example, the second display control parameter may be determined in advance in the same manner as the first display control parameter, and then the second display control parameter is acquired at the time of displaying each picture, and when the second display control parameter is determined, the display parameter of the second display region may include only at least one of the display duration and the current corresponding to the tie point gray-scale voltage. For another example, the second display control parameter may also be a fixed Gamma curve, and at this time, it is not necessary to determine in advance, and the second display control parameter is obtained when each picture is displayed, in which case, the second display area may be implemented by completing display correction by internal compensation and changing a circuit structure (e.g., a threshold compensation circuit such as 6T 1C) in the array structure.

In step S24, the gray scale of each sub-pixel located in the first display region and the gray scale of each sub-pixel located in the second display region in the target screen are obtained.

In step S25, determining data voltages of the respective sub-pixels of the first display region of the display panel based on the first display control parameter and the gray scales of the respective sub-pixels located in the first display region; and determining the data voltage of each sub-pixel in the second display area of the display panel based on the second display control parameter and the gray scale of each sub-pixel in the second display area.

For example, when the display control parameter (the first display control parameter or the second display parameter) is a Gamma curve, step S25 may include: and selecting corresponding data voltage from the Gamma curve according to the gray scale value, and controlling the pixel to display by adopting the selected data voltage.

When the display control parameter is the display correction coefficient, step S25 may include: adjusting the Gamma curve used by the first display area by adopting the display correction coefficient; and selecting corresponding data voltage from the adjusted Gamma curve according to the gray scale value, and controlling the pixel to display by adopting the selected data voltage.

In step S26, the data voltage of each subpixel in the first display region is input to each subpixel in the first display region, and the data voltage of each subpixel in the second display region is input to each subpixel in the second display region.
