In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Fig. 1 is a diagram of an implementation environment of a method for adjusting screen flickering provided in an embodiment, as shown in fig. 1, in the implementation environment, including a screen 100, a debugging device 200, and a data collector 300.
The screen 100 is a module that is installed in any device requiring a display interface and provides the display interface for the device. The screen 100 may be installed in a mobile terminal, a wearable device, a display, a home appliance, a machine tool, a robot, and other various devices requiring a display interface. The debugging apparatus 200 is an apparatus used by a user to debug the screen 100, and can control various display parameters of the screen 100 and adjust the degree of screen flicker. The data collector 300 is a device for collecting various data parameters of the screen 100, and is mounted on the screen 100 and includes various sensors, such as a light sensor, a position sensor, and the like. In the using process, the debugging device 200 controls the screen 100 to switch the frequency between the two frequency groups, the data collector 300 collects the brightness change curve of the screen 100 when the frequency is switched between the two frequency groups and sends the brightness change curve to the debugging device 200, and the debugging device 200 changes the charging time of the pixel components corresponding to the two frequency groups according to the brightness change curve, that is, completes one-time debugging.
It should be noted that, the debugging device 200, the screen 100 and the data collector 300 may be connected through wired or wireless or other communication connection manners, and the invention is not limited herein.
As shown in fig. 2, in an embodiment, a method for adjusting screen flickering is provided, where the method for adjusting screen flickering can be applied to the debugging device 200, and specifically includes the following steps:
step S100, a refresh rate group comparison pair is selected in sequence from a plurality of groups of refresh rate groups in the refresh rate range of the screen, the refresh rate group comparison pair comprises a first refresh rate group and a second refresh rate group, and the refresh rate in the first refresh rate group is lower than that of the second refresh rate group.
In the embodiment of the present disclosure, before debugging the screen 100, the refresh rate of the screen 100 needs to be divided into a plurality of groups of refresh rate groups from large to small, and then two refresh rate groups are selected from the plurality of groups of refresh rate groups to form a pair of refresh rate group comparison pairs, so as to control the screen 100 to switch between the two refresh rate groups in the subsequent step, and compare the brightness change of the screen 100 when switching between the two refresh rate groups.
Specifically, in some embodiments, a specific implementation of step S100 may be found in fig. 3. Fig. 3 is a detailed description of step S100 in the method for adjusting screen flickering shown in the corresponding embodiment of fig. 2, wherein step S100 may include the following steps:
step S110, acquiring the highest refresh rate and the lowest refresh rate of the screen.
And step S120, dividing the refresh rate of the screen into a plurality of groups of refresh rate groups according to the highest refresh rate and the lowest refresh rate of the screen.
In this embodiment, the refresh rate of the screen may be divided into the plurality of groups of refresh rate groups according to the highest refresh rate and the lowest refresh rate of the screen, so as to ensure that the refresh rate is changed in a gradient manner during adjustment. Specifically, the difference between the highest refresh rate and the lowest refresh rate may be obtained first, and then divided by the number of groups to be divided to obtain the variation range value of each group of refresh rate groups, and the refresh rate of the screen is divided into a plurality of groups of refresh rate groups according to the variation range value.
For example, in one embodiment of the present disclosure, the highest refresh rate of the screen 100 is 120Hz, and the lowest refresh rate is 30Hz, and the difference between the highest refresh rate and the lowest refresh rate is 90 Hz. Then, according to actual requirements, the refresh rate of the screen 100 needs to be divided into 3 groups of refresh rate groups, and the variation range value of each group of refresh rate groups is 30Hz, so that three groups of refresh rate groups of 30Hz to 60Hz, 60Hz to 90Hz, and 90Hz to 120Hz are obtained for the 3 groups of refresh rate groups. In the practical application process, in consideration of the user experience, the adjustment precision needs to be finer, so that the divided refresh rate groups are not only 3 groups, and for simplicity and convenience of description in this embodiment, only the division into 3 groups is taken as an example for description.
The method can flexibly control the adjustment precision and control the group number of the refresh rate groups within a reasonable range. When the refresh rate variation range of the screen is large, the number of groups of the refresh rate group can be controlled not to be too large by abandoning certain precision. When the refresh rate variation range of the screen is small, the adjustment precision can be ensured by increasing the number of groups.
Step S200, aiming at each refresh rate group comparison pair, controlling the screen to switch between a first refresh rate group and a second refresh rate group in the refresh rate group comparison pair, and acquiring the flicker value of the screen when the refresh rate is switched.
After determining the refresh rate group comparison pair, the screen 100 may be controlled to switch between the first refresh rate group and the second refresh rate group in the refresh rate group comparison pair, and meanwhile, the data collector 300 obtains the flicker value of the screen 100 when the refresh rate is switched.
The manner of switching the control screen 100 between the first refresh rate group and the second refresh rate group in the refresh rate group comparison pair may be to select one refresh rate from the first refresh rate group and the second refresh rate group as a target refresh rate during switching, where the target refresh rate is a first target refresh rate and a second target refresh rate, respectively, and then control the screen 100 to switch between the first target refresh rate and the second target refresh rate.
The above three groups of refresh rate groups of 30 Hz-60 Hz, 60 Hz-90 Hz, and 90 Hz-120 Hz are used as examples for explanation. In this embodiment, if the variation ranges of the refresh rates in the first refresh rate group and the second refresh rate group are 30Hz to 60Hz, and 60Hz to 90Hz, respectively, the first target refresh rate and the second target refresh rate selected to correspond to each other are 45Hz and 75Hz, respectively, and the control of the screen 100 to switch between 45Hz and 75Hz means that the control of the screen 100 to switch between the first refresh rate group and the second refresh rate group in the refresh rate group comparison pair.
The switching method can ensure the reliability of subsequent adjustment, the adjustment of the charging time in each subsequent time is the adjustment of the brightness corresponding to 45Hz in the first refresh rate group and 75Hz in the second refresh rate group, and the stability and the reliability of the adjustment data are ensured. Meanwhile, further, when the target refresh rate is selected, the intermediate value in the refresh rate group is preferably selected, and meanwhile, the difference between the first target refresh rate and the second target refresh rate should be equal to the variation range value of each group of refresh rate group, so as to ensure the gradient of the adjustment data. For example, the target refresh rates corresponding to three groups of refresh rates of 30 Hz-60 Hz, 60 Hz-90 Hz, and 90 Hz-120 Hz can be respectively selected from 45Hz, 75Hz, and 105 Hz.
The manner of obtaining the flicker value of the screen 100 when the refresh rate is switched by the data collector 300 may be that the data collector 300 obtains the brightness of the screen 100 when the refresh rate is switched, draws a function curve of the brightness of the screen and time in the time period, calculates the flicker value of the screen 100 according to the function curve, and finally sends the flicker value to the debugging device 200.
In other embodiments, the data collector 300 may also obtain the brightness of the screen 100 when the refresh rate is switched, draw a function curve of the screen brightness and time in the time period, and send the function curve to the debugging device 200. The debugging apparatus 200 calculates the flicker value of the screen 100 according to the function curve.
And step S300, adjusting the charging time of the pixel assembly corresponding to the target refresh rate group in the first refresh rate group or the second refresh rate group according to the flicker value, so that the flicker value meets a preset brightness stability condition.
In the prior art, since the conventional display devices all operate at a fixed refresh rate, the time for each refresh is consistent, and the charging time of the pixel element is fixed for each refresh. However, after the VRR technique is applied, the display device does not operate at a fixed refresh rate, the time spent each time is not consistent, the time spent in refreshing at the low frame rate is longer than the time spent in refreshing at the high frame rate, and the charging time of the pixel component at each frame rate is changed, so that the amount of electric power which is leaked in each refresh at the low frame rate relative to the drain electrode of the pixel component refreshed at each refresh at the high frame rate can be effectively compensated, the consistency of the residual electric power of the pixel component at each refresh rate is ensured, and the brightness at each refresh rate is also ensured to be consistent.
The method provided by the present disclosure is applicable to various types of screen modules, including Liquid Crystal Display (LCD) screens and Organic Light-Emitting Diode (OLED) screens. When the pixel component is an LCD screen, the charging time of the pixel component is the charging time of the liquid crystal during each refreshing, the longer the charging time is, the more the electric quantity is, the larger the liquid crystal deflection angle is, and the higher the screen brightness is.
When the pixel module is an OLED screen, the charging time of the pixel module is the charging time of a Micro Light-Emitting Diode (Micro LED) in each refresh, and the longer the charging time is, the more the electric quantity is, the brighter the Micro LED is, and the higher the screen brightness is.
Optionally, the predetermined brightness stabilization condition includes the flicker value reaching a minimum value or the flicker value being less than a predetermined threshold.
In an embodiment of the disclosure, the predetermined brightness stabilization condition is that the flicker value is smaller than a predetermined threshold. The flicker value is determined according to the brightness change when the two frames of pictures are switched, and the lower the flicker value is, the smaller the brightness difference between the two frames of pictures is, the less easily people can feel the brightness change, and the flicker can not be felt. Therefore, the predetermined threshold may be-40, -50 or-60, and the disclosure is not limited thereto, and the lower the predetermined threshold is, the less susceptible a person is to sense the change of brightness, and the less susceptible the person is to sense flicker. Meanwhile, the predetermined threshold value cannot be higher than-40. When the screen 100 switches the picture, the corresponding flicker value is within-40, human eyes cannot feel the difference of brightness, namely cannot feel that the display device flickers, and at this time, the problem that the screen 100 is easy to flicker when the refresh rate is changed is solved.
In another embodiment of the present disclosure, the predetermined luminance stabilization condition is that the flicker value reaches a minimum value. The lower the flicker value is, the smaller the brightness difference between the two frames of pictures is, the more difficult it is to make people feel the change of brightness, and the people cannot feel flicker.
When the refresh rate groups are more than three groups, the above-mentioned three groups of 30 Hz-60 Hz, 60 Hz-90 Hz, and 90 Hz-120 Hz are still used as an example for explanation. The debugging device 200 will form a refresh rate group comparison pair by two groups of refresh rate groups of 30 Hz-60 Hz and 60 Hz-90H, adjust the charging time of the pixel components corresponding to the two groups of refresh rate groups, then form a refresh rate group comparison pair by two groups of refresh rate groups of 60 Hz-90 Hz and 90 Hz-120 Hz, adjust the charging time of the pixel components corresponding to the two groups of refresh rate groups, finally form a refresh rate group comparison pair by two groups of refresh rate groups of 90 Hz-120 Hz and 30 Hz-60 Hz, and adjust the charging time of the pixel components corresponding to the two groups of refresh rate groups.
After one round of adjustment, if the charging time of the pixel components corresponding to the two groups of refresh rate groups forming the refresh rate group comparison pair is adjusted every time of adjustment, the flicker values corresponding to the two groups of refresh rate groups forming the refresh rate group comparison pair by 30 Hz-60 Hz and 60 Hz-90H which are adjusted first may no longer satisfy the preset condition again, and at this time, cyclic adjustment is required until the flicker values satisfy the preset condition, for example, the flicker values are all smaller than the preset threshold value of-40, or all reach a relative minimum value. Or only adjusting the charging time of the pixel assemblies corresponding to one group of refresh rate groups during each adjustment, and selecting one group of refresh rate groups from the plurality of refresh rate groups as a never-adjusted reference group, thereby effectively reducing the number of adjustment rounds.
In particular, in some embodiments, the specific implementation of step 300 may be the steps illustrated in fig. 4. Optionally, fig. 4 is a detailed description of step S300 in the method for adjusting screen flickering shown in the corresponding embodiment of fig. 2, where in the method for adjusting screen flickering, the target refresh rate group includes a first refresh rate group and a second refresh rate group, and step S300 may include the following steps:
step S310, increasing the charging time of the pixel assembly corresponding to the first refresh rate group by a predetermined time increment threshold.
Step S320, reducing the charging time of the pixel assembly corresponding to the second refresh rate group by a predetermined time decrement threshold.
In the embodiment of the present disclosure, step S310 and step S320 may be executed synchronously or asynchronously, and in asynchronous execution, step S310 may be executed first and then step S320 is executed, or step S320 may be executed first and then step S310 is executed, which is not limited in this disclosure.
Meanwhile, referring to fig. 5, Gate represents the level change of the Gate electrical signal, and Data represents the level change of the source electrical signal. The specific implementation manner of step S310 is to change the timing sequence of the electrical signal at the receiving end of the pixel element of the screen, so that the delay between the timing sequence of the electrical signal at the gate of the pixel element and the timing sequence of the electrical signal at the source of the pixel element is smaller. Therefore, the time from the starting time of the high-frequency electric signal of the source electrode of the pixel component to the ending time of the high-frequency electric signal of the grid electrode of the pixel component is prolonged, and the charging time of the pixel component is prolonged each time. Specifically, the timing of the electrical signal at the gate of the pixel element may be delayed or the timing of the electrical signal at the source of the pixel element may be advanced.
Referring to fig. 6, Gate represents the level variation of the Gate electrical signal, and Data represents the level variation of the source electrical signal. The specific implementation manner of step S320 is to change the electrical signal timing sequence of the receiving end of the pixel assembly of the screen, so that the delay between the electrical signal timing sequence of the gate of the pixel assembly and the electrical signal timing sequence of the source of the pixel assembly is larger. Therefore, the time from the starting time of the high-frequency electric signal of the source electrode of the pixel component to the ending time of the high-frequency electric signal of the grid electrode of the pixel component is shortened, and the charging time of the pixel component each time is shortened. Specifically, the timing of the electrical signal at the gate of the pixel element may be advanced or delayed, and in this embodiment, the timing of the electrical signal at the source of the pixel element is delayed, because it is simpler to change the timing of the electrical signal at the source of the pixel element than to change the timing of the electrical signal at the gate of the pixel element.
In other embodiments of the present disclosure, the target refresh rate set includes only the first refresh rate set, and at this time, the step S300 may include the steps of:
step S310, increasing the charging time of the pixel assembly corresponding to the first refresh rate group by a predetermined time increment threshold.
The specific implementation manner of step S310 is to change the timing sequence of the electrical signal at the receiving end of the pixel element of the screen, so that the delay between the timing sequence of the electrical signal at the gate of the pixel element and the timing sequence of the electrical signal at the source of the pixel element is smaller. Therefore, the time from the starting time of the high-frequency electric signal of the source electrode of the pixel component to the ending time of the high-frequency electric signal of the grid electrode of the pixel component is prolonged, and the charging time of the pixel component at each time is prolonged. Specifically, the timing of the electrical signal at the gate of the pixel element may be delayed or the timing of the electrical signal at the source of the pixel element may be advanced.
In still other embodiments of the present disclosure, the target refresh rate set includes only the second refresh rate set, and step S300 may include the steps of:
step S320, reducing the charging time of the pixel assembly corresponding to the second refresh rate group by a predetermined time decrement threshold.
The specific implementation manner of step S320 is to change the electrical signal timing sequence of the receiving end of the pixel assembly of the screen, so that the delay between the electrical signal timing sequence of the gate of the pixel assembly and the electrical signal timing sequence of the source of the pixel assembly is larger. Therefore, the time from the starting time of the high-frequency electric signal of the source electrode of the pixel component to the ending time of the high-frequency electric signal of the grid electrode of the pixel component is shortened, and the charging time of the pixel component each time is shortened. Specifically, the timing of the electrical signal at the gate of the pixel element may be advanced or delayed, and in this embodiment, the timing of the electrical signal at the source of the pixel element is delayed, because it is simpler to change the timing of the electrical signal at the source of the pixel element than to change the timing of the electrical signal at the gate of the pixel element.
In addition to the three embodiments described above, in some other embodiments of the present disclosure, the selected target refresh rate set may be different each time the adjustment is performed, for example, the first selected target refresh rate set has only a first refresh rate set, the second selected target refresh rate set includes the first refresh rate set and a second refresh rate set, and the third selected target refresh rate set includes only the second refresh rate set. The selection of the target refresh rate set is determined according to the constitutions of the different screens 100, and the variable amounts that can be changed in the different refresh rate sets are not necessarily consistent.
As shown in fig. 7, in an embodiment, a device for adjusting screen flickering is provided, and the agent workstation management device may be integrated in the debugging apparatus 200, and specifically may include a selecting unit 210, a measuring unit 220, and an adjusting unit 230.
The selecting unit 210 is configured to sequentially select a refresh rate group comparison pair from a plurality of groups of refresh rate groups within a refresh rate range of a screen, where the refresh rate group comparison pair includes a first refresh rate group and a second refresh rate group, and refresh rates in the first refresh rate group are all lower than refresh rates in the second refresh rate group;
