Detailed Description
Features and exemplary embodiments of various aspects of the present application will be described in detail below, and in order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be described in further detail below with reference to the accompanying drawings and the detailed embodiments. It should be understood that the particular embodiments described herein are meant to be illustrative of the application only and not limiting. It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the application by showing examples of the application.
With the development of display technology, the functions of the display device are also increasing. In order to realize the functions of display, shooting, sensitization and the like, a sensitization component such as a camera, an infrared sensing element and the like needs to be integrated in a display device. Meanwhile, the requirements of users on the screen occupation ratio are gradually increased, in order to realize the full screen, a light-transmitting display area can be arranged on the display device, and photosensitive components such as a camera and an infrared sensing element are arranged on the back of the light-transmitting display area, so that the full screen display of the display device is realized under the condition that the normal operation of the photosensitive components such as the camera and the infrared sensing element is ensured.
The display device may include, but is not limited to, a device having a display function such as a mobile phone, a computer, a tablet computer, a television, an electronic paper, and the like.
In order to improve the light transmittance of the light-transmitting display area, the pixel structure, the pixel density and the like of the light-transmitting display area and other display areas of the display device are different, and the light-transmitting display area and other display areas of the display device have the problem of inconsistent display, for example, the light-transmitting display area and other display areas of the display device have the problem of inconsistent display brightness, color cast of the light-transmitting display area and the like.
The display compensation method, the display device and the storage medium provided by the embodiment of the application can be used for superposing the layers on the light-transmitting display area of the display device or other display areas except the light-transmitting display area of the display device so as to compensate the condition that the light-transmitting display area of the display device is inconsistent with the display of the other display areas of the display device, so that the light-transmitting display area of the display device is approximately or consistent with the display of the other display areas of the display device.
For ease of understanding, the display device will be described first. Fig. 1 is a schematic top view of an example of a display device according to an embodiment of the present application. As shown in fig. 1, the display device has a first display area AA1 and a second display area AA2. The display device may also be provided with a non-display area NA, which may be disposed around the first display area AA1 and the second display area AA2. The first display area AA1 is the light-transmitting display area in the above description.
The light transmittance of the first display area AA1 is greater than that of the second display area AA 2. For example, the light transmittance of the first display area AA1 may be greater than or equal to 15%, and in order to ensure that the light transmittance of the first display area AA1 is greater than 15%, even greater than 40%, even higher, the light transmittance of each functional film layer of the display panel of the display device in the embodiment of the present application may be greater than 80%, even at least a portion of the functional film layers have a light transmittance of greater than 90%.
In some examples, the second display area AA2 may include a first sub-area and a second sub-area. Fig. 2 is a schematic top view of another example of a display device according to an embodiment of the present application. As shown in fig. 2, the first sub-area AA21 is located between the second sub-area AA22 and the first display area AA1, surrounding at least a portion of the first display area AA 1. The second sub-area AA22 surrounds at least part of the first sub-area AA 21. The light transmittance of the first sub-area AA21 is smaller than that of the first display area AA1, and the light transmittance of the first sub-area AA21 is larger than that of the second sub-area AA 22.
In the embodiment of the application, the pixel density (Pixels Per Inch, PPI) in the first display area AA1 may be lower than the pixel density in the second display area AA2, and the volume of the pixels in the first display area AA1 may be smaller than the volume of the pixels in the second display area AA2, so as to improve the light transmittance of the first display area AA 1.
The display compensation method provided by the application can be applied to the display device. Specifically, the display compensation method may be performed by a display device. Fig. 3 is a flowchart of an embodiment of a display compensation method according to the present application. As shown in fig. 3, the display compensation method may include steps S301 to S304.
In step S301, a layer display compensation parameter corresponding to the target area generated by the display compensation adjustment input is acquired.
The target area includes a first display area or a second display area, and specific contents of the first display area and the second display area may be referred to the above related description, which is not repeated herein.
The display compensation adjustment input is an input that compensates for the display of the target area. The display compensation adjustment input may be a key input to the display device, a touch click input to the display device, or a touch slide input to the display device, and the specific form of the display compensation adjustment input is not limited herein.
The display compensation adjustment input may generate a layer display compensation parameter. The layer display compensation parameter is a compensation parameter for the target area, and can compensate the display of the target area. In some examples, the layer display compensation parameters may include color values and/or transparency. The color values are color values corresponding to the colors, and can comprise a red value, a green value and a blue value, and the colors can be adjusted by adjusting the red value, the green value and the blue value. The transparency is the transparency of the image, and the brightness can be adjusted by adjusting the transparency.
For example, fig. 4 is a schematic diagram of an example of an interface for displaying a compensation adjustment input on a display device according to an embodiment of the present application. The layer display compensation parameters include color values and transparency. As shown in fig. 4, the interface may include a red color bar, a green color bar, a blue color bar, and a transparency bar. The display compensation adjustment input may specifically be a slide input to a slide of red values, a slide of green values, a slide of blue values, and a slide of transparency, and the layer display compensation parameters generated by the display compensation adjustment input correspondingly include red values, green values, blue values, and transparency.
In some examples, the position, size, and shape of the target area may be set in advance by a software program for a display device of a different model so that the target area can coincide with the first display area or the second display area.
In other examples, displaying the compensation adjustment input may also include adjusting the input of the target area. The display device determines a location of the target area in response to an input to adjust the target area. The target area may be determined at any one of positions in a display area of the display device, and adjusting the input of the target area may also be used to set the size and shape of the display area so that the target area may coincide with the first display area or the second display area. For different types of display devices, the user-defined setting of the target area can be realized.
In step S302, a target display layer of the target area is generated from the layer display compensation parameters.
The target display layer is located in the target area. The layer display compensation parameters may be used to generate a target display layer. In some examples, the target display layer may be a solid color layer with a certain transparency. In other examples, the target display layer may be a colorless layer having a certain transparency. Different target display layers may be generated based on different layer display compensation parameters. For example, the layer display compensation parameters include a color value and a transparency, and the transparency is the same and the color value is different in the two groups of layer display compensation parameters, so that the two target display layers respectively generated according to the two groups of layer display compensation parameters are the same and different in color. For another example, the layer display compensation parameters include transparency, and if the transparency of the two groups of layer display compensation parameters is different, the transparency of the two target display layers respectively generated according to the two groups of layer display compensation parameters is different.
In step S303, the target display layer is superimposed on the original layer of the target region, and the image of the target region is displayed so that the display effect of the target region is similar or identical to the display effect of the display device in the display region other than the target region.
The original image layer of the target area is an image which the target area should display without overlapping the target display image layer. And superposing the target display image layer and the original image layer of the target area to adjust the display effect of the target area, so that the display effect of the image displayed by the target area is similar to or consistent with the display effect of other display areas except the target area, namely, the parameters representing the display effect of the target area are similar to or consistent with the parameters representing the display effect of the display device except the target area. The display effect of the target area being similar to the display effect of the display device other than the target area means that there may be a gap between the display effect of the target area and the display effect of the display device other than the target area, but the gap is within an acceptable error range. Specifically, the display effect of the target area being similar to the display effect of the display device other than the target area may mean that there may be a gap between a parameter characterizing the display effect of the target area and a parameter characterizing the display effect of the display device other than the target area, but the gap is to be within an acceptable error range. The display effect of the target area is identical to the display effect of the display device other than the target area, which means that the display effect of the target area is identical to the display effect of the display device other than the target area, and specifically, the parameter characterizing the display effect of the target area is identical to the parameter characterizing the display effect of the display device other than the target area. For example, if the display effect of the target area and the display effect of the display device other than the target area satisfy the approximation or agreement of human eyes, the display effect of the target area and the display effect of the display device other than the target area can be considered to be approximated or agreement.
In some examples, the parameters characterizing the display effect may include color cast and/or brightness. The degree of color shift may also be referred to as a degree of color deviation or color standard. And superposing the generated target display image layer corresponding to the color value with the original image layer of the target area by adjusting the color value in the image layer display compensation parameter so as to adjust the color deviation degree of the target area, so that the color deviation degree of the target area is approximate to or consistent with the color deviation degree of the display area of the display device except the target area. And superposing the generated target display image layer corresponding to the transparency with the original image layer of the target area by adjusting the transparency in the image layer display compensation parameter so as to adjust the brightness of the target area, so that the brightness of the target area is approximate to or consistent with the brightness of the display area of the display device except the target area.
For example, the target area is illustrated as including a first display area. Fig. 5 is a schematic diagram of an example of an image displayed in a display area of a display device according to an embodiment of the present application. As shown in fig. 5, the diagonal line filling pattern is an image of the original layer of the first display area and the original layer of the second display area, and the dot-like filling pattern is a target display layer of the first display area. And finally displaying an image in the first display area, namely, superposing an original image layer and a target display image layer in the first display area.
In some examples, the layer display compensation parameter includes transparency. The layer display compensation parameters may also include other parameters, not limited herein, on the basis that the layer display compensation parameters include transparency.
The target area includes one of the first display area and the second display area that is brighter. Specifically, in the case where the luminance of the first display area is greater than the luminance of the second display area, the target area includes the first display area, and the display area of the display device other than the target area includes the second display area; in the case where the luminance of the first display area is smaller than the luminance of the second display area, the target area includes the second display area, and the display area of the display device other than the target area includes the first display area. By adjusting the transparency in the layer display compensation parameters, a target display layer with a certain transparency can be generated, the target display layer is overlapped with the original layer, the brightness of the target area display can be reduced, and the display area with relatively higher brightness in the first display area and the second display area is used as the target area.
In other examples, the target area may include the first display area if the accumulated display duration of the display device is less than a preset brightness variation duration threshold; the target area may include the second display area in a case where the accumulated display time period of the display device is greater than or equal to a preset brightness variation time period threshold. The accumulated display time is the accumulated time of the display after the display device leaves the factory. The preset brightness change duration threshold is a duration threshold for changing from the brightness of the first display area being higher than the brightness of the second display area to the brightness of the first display area being lower than the brightness of the second display area. The light transmittance of the first display area is higher than that of the second display area, and correspondingly, the pixel structure, the pixel density and the like of the pixels of the first display area and the pixels of the second display area are different.
When the accumulated display duration is smaller than the threshold value of the preset brightness change duration, the delivery time of the display device is shorter, the temperature of the screen body of the first display area and the temperature of the screen body of the second display area in the display device are raised simultaneously when the screen body of the first display area and the screen body of the second display area work, and at the same temperature, the brightness of the first display area and the brightness of the second display area are reduced, but the brightness of the second display area is reduced more, so that the brightness of the first display area is larger than the brightness of the second display area, and in this case, the first display area is determined as a target area to be overlapped with the target display layer, so that the brightness of the first display area is reduced, and the brightness of the first display area is approximate to or consistent with the brightness of the second display area.
When the accumulated display time length is greater than or equal to the preset brightness change time length threshold, the delivery time of the display device is longer, the pixel volume in the first display area is smaller than the pixel volume in the second display area, correspondingly, the working current required by the pixels in the first display area is greater than the working current required by the pixels in the second display area, under the influence of the large working current, the first display area decays faster than the second display area, so that the brightness of the first display area is smaller than the brightness of the second display area, and in this case, the second display area is determined as a target area to overlap the target display layer, so that the brightness of the second display area is reduced, and the brightness of the second display area is approximate to or consistent with the brightness of the first display area.
In the embodiment of the application, the target display layer of the first display area or the second display area of the display device can be generated according to the layer display compensation parameters corresponding to the first display area or the second display area of the display device generated by the display compensation adjustment input. And superposing the target display layer and the original layer of the corresponding first display area or second display area, and compensating to ensure that the display effect of the first display area or the second display area after the target display layer is superposed is approximate or consistent with the display effect of the second display area or the first display area without the target display layer, thereby improving the display effect of the display device.
The target display layer is overlapped with the original layer of the target area, and display control data for controlling the display image can be processed to obtain display control data corresponding to the image of the target area after the target display layer is overlapped, so that the display effect of the target area is changed. Fig. 6 is a flowchart of another embodiment of a display compensation method according to the present application. Fig. 6 is different from fig. 3 in that step S303 in fig. 3 may be specifically thinned into step S3031 and step S3032 in fig. 6.
In step S3031, the display control data of the original layer of the target area is adjusted according to the layer display compensation parameter of the target display layer, so as to obtain the target display control data of the target area.
The target display control data is display control data of a target area. The display control data is used to control the drive current of the pixel display. The display control data of the original layer of the target area is used for controlling the pixel of the target area to display the driving current corresponding to the image of the original layer. The target display control data of the target area is used for controlling the driving current corresponding to the image of which the original image layer is overlapped with the target display image layer.
The target display layer generated according to the layer display compensation parameters can adjust display control data according to the effect brought by the layer display compensation parameters on the target region. For example, the layer display compensation parameter includes a color value, and the target display layer generated according to the color value changes the color deviation of the display of the target area, correspondingly, the display control data may be specifically adjusted to obtain target display control data, where the driving current of the red pixel, the driving current of the green pixel, and the driving current of the blue pixel represented by the target display control data are different relative to the driving current of the red pixel, the driving current of the green pixel, and the driving current of the blue pixel represented by the display control data before adjustment. For another example, the layer display compensation parameter includes transparency, and the target display layer generated according to the transparency may reduce the brightness of the display of the target area, and for one you can specifically adjust the display control data to obtain the target display control data, where the driving current of the pixel represented by the target display control data is smaller than the driving current of the pixel represented by the display control data before adjustment.

After the display device automatically adjusts the display brightness, the display device can read the first display brightness. The first display brightness is the display brightness after the change value of the sensed ambient brightness exceeds the preset fluctuation range and the display device automatically adjusts the brightness.
In step S307, the layer display compensation parameter corresponding to the second display brightness is adjusted according to the difference between the first display brightness and the second display brightness, so as to obtain the layer display compensation parameter corresponding to the first display brightness.

In step S308, a target display layer with updated target area is generated according to the layer display compensation parameter corresponding to the first display brightness.
The target display layer after the target area update is the target display layer corresponding to the first display brightness. The layer display compensation parameter corresponding to the first display luminance is different from the layer display compensation parameter corresponding to the second display luminance, and correspondingly, the target display layer corresponding to the first display luminance is different from the target display layer corresponding to the second display luminance.
In step S309, the updated target display layer is superimposed with the original layer of the target area, and the image of the target area is displayed.
The displayed image of the target area is the original image layer of the target display image layer after superposition updating.
Under the condition that the ambient brightness is greatly changed, the display device can automatically adjust the layer display compensation parameters, and the superposition of the target display layer and the original layer generated according to the adjusted layer display compensation parameters is executed, so that the automation of the display compensation of the display device is realized, the user operation can be reduced, and the user experience is improved.
