[0018] The technical solutions in the embodiments of the present application are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. In the absence of conflict, the following embodiments and their technical features can be combined with each other.

[0019] Figure 1 FIG. 1 is a flowchart of a display compensation method according to an embodiment of the present application. Figure 1 As shown, the display compensation method applied to the display panel includes the following steps:

[0020] Step 101 : In response to a first instruction, determine compensated display data according to original data of a first display area.

[0021] Step 102 : performing display compensation on the first display area according to the compensated display data, so that the difference between the brightness of the compensated first display area and the brightness of the first display area in the first state is less than a first preset difference.

[0022] The display panel includes a first display area and a second display area. When receiving the first instruction, the brightness of the second display area will be increased so that the increased brightness of the second display area is greater than the brightness of the first display area before responding to the first instruction. At the same time, since the display panel does not have a low brightness problem when it is at a high brightness level, the brightness level of the first display area before responding to the first instruction is less than the first preset brightness level. At this time, the display data of the first display area is the original data. Due to the increase in the brightness of the second display area, the display mode of the screen has changed, switching from the previous PWM dimming mode to the DC dimming mode. At this time, the first display area can no longer use the compensation method in the previous dimming mode, so it is necessary to respond to the first instruction and obtain the compensated display data according to the original data of the first display area. The difference between the brightness of the first display area after displaying the first display area with the compensated display data and the brightness of the first display area in the first state is less than the first preset difference. It should be noted that the brightness level of the second display area in the first state is less than the second preset brightness level.

[0023] In an embodiment of the present application, by determining compensated display data based on the original data of the first display area when increasing the brightness of the second display area in response to the first instruction, and then performing display compensation on the first display area using the compensated display data, the brightness difference of the first display area before and after the brightness adjustment of the second display area can be made less than a first preset difference, thereby avoiding screen flickering.

[0024] Figure 2 is a schematic diagram of a display panel applicable to an embodiment of the present application, such as Figure 2As shown, among the existing electronic products, some electronic products provide the function of fingerprint unlocking under the screen, so a light spot for fingerprint unlocking is included in the screen (i.e., the second display area). When the fingerprint is unlocked, the light spot will emit a high-brightness light of about 1200nit, and the brightness of the other parts of the screen (i.e., the first display area) will change with the settings of the electronic product. When the screen leaves the factory, in order to improve the display effect during low-brightness display, the color coordinates will be pulled and the gamma will be pulled. For example, when the screen is displayed at a display brightness value of 2nit (i.e., in the first state), the display brightness of some 32 grayscale pixel units is about 0.02nit. At this time, the brightness is too low and the display effect is too poor. A certain compensation is made by pulling the color coordinates and pulling the gamma, so that the display brightness of some 32 grayscale pixel units is about 0.03nit, thereby improving the display effect. However, when the light spot is used for fingerprint unlocking, the display mode of the screen changes from the previous PWM dimming mode to the DC dimming mode. At this time, other parts of the screen need to be suppressed by a certain coefficient, such as 90nit, to obtain the same brightness before the light spot is used for fingerprint unlocking. It can be understood that since the brightness of the screen is suppressed by a certain coefficient when the light spot is used for fingerprint unlocking, it is not pulled by the color coordinates and gamma. Therefore, before and after the light spot is used for fingerprint unlocking, other parts of the screen except the light spot will have brightness differences and chromaticity differences, resulting in the problem of flickering on the screen. Based on the above scenario, the first instruction is a fingerprint recognition instruction, and the display panel will enter the fingerprint unlocking state in response to the first instruction, and increase the brightness of the light spot. The brightness of the second display area in the first state is the brightness before responding to the first instruction (i.e. entering the fingerprint unlocking state). Specifically, the range of the first preset brightness level can be [11nit, 20nit]. For example, the first preset brightness level is 11nit-20nit, such as 12nit, 16nit, 20nit, etc. It can be seen that the first preset brightness level is low, so when the brightness level of the first display area is less than the first preset brightness level (i.e., in the first state), there will be a problem of low-brightness display, so the color coordinate deviation and gamma deviation described above will be performed, thereby changing the final display level brightness. When the PWM dimming mode is switched to the DC dimming mode, the color coordinate deviation and gamma deviation cannot be performed in the same way, so it is necessary to determine the compensated display data based on the original data of the first display area, and perform display compensation on the first display area based on the compensated display data, so that the brightness difference between the compensated first display area and the brightness of the first display area in the first state is less than the first preset difference. In addition, the chromaticity difference between the compensated first display area and the chromaticity of the first display area in the first state is less than the second preset difference.In an ideal situation, the first preset difference is zero, and the second preset difference is zero, that is, the brightness of the compensated first display area is the same as the brightness of the first display area in the first state, and the chromaticity of the compensated first display area is the same as the chromaticity of the first display area in the first state.

[0025] Specifically, the process of determining the compensated display data according to the original compensation data of the first display area may further include:

[0026] The compensated display data is determined according to the first corresponding relationship and the original data of the first display area, wherein the first corresponding relationship includes a corresponding relationship between the original data and the compensated display data or a corresponding relationship between the original data and the compensation value.

[0027] In order to determine the compensated display data, it can be determined based on the first corresponding relationship and the original data of the first display area. The first corresponding relationship can be the corresponding relationship between the original data and the compensated display data. In this case, the compensated display data can be directly obtained based on the original data. The first corresponding relationship can also be the corresponding relationship between the original data and the compensation value. In this case, the compensation value can be obtained based on the original data and the first corresponding relationship. The compensation value is then superimposed on the brightness of the first display area when responding to the first instruction to obtain the compensated display data.

[0028] Specifically, the first display area includes a plurality of pixels, and the difference between the brightness of the plurality of pixels after compensation and the brightness in the first state is less than the first preset difference. In addition, the difference between the chromaticity of the plurality of pixels after compensation and the chromaticity in the first state may also be less than the first preset difference. It should be noted that the first preset difference is a pure value, and when making a comparison, the difference between the brightness of the plurality of pixels after compensation and the brightness in the first state, or the difference between the chromaticity of the plurality of pixels after compensation and the chromaticity in the first state are converted into pure values.

[0029] Specifically, the display compensation process may also include: in response to the first instruction, increasing the brightness of the second display area to a first preset brightness. Preferably, the range of the first preset brightness is [900nit, 1300nit]. For example, the first preset brightness may be 1000nit, 1100nit or 1200nit, etc. In response to the first instruction, the second display area, that is, the light spot, will be illuminated to the first preset brightness. In order to ensure fingerprint recognition, it is necessary to ensure that the brightness of the second display area is high enough. Therefore, the range of the first preset brightness needs to be [900nit, 1300nit].

[0030] Figure 3 is a flowchart of the steps of the method for obtaining the first corresponding relationship, such as Figure 3 As shown, the method for obtaining the first corresponding relationship includes the following steps:

[0031] Step 201 : respectively obtaining, when a first display area of ​​a display panel is at a third brightness level and a fourth brightness level, a second binding point grayscale value at a fourth brightness level corresponding to an actual brightness of a first binding point grayscale value at a third brightness level.

[0032] Step 202: Taking the actual brightness of the first display area corresponding to the grayscale value of the first binding point at the third brightness level as the target brightness.

[0033] Step 203: adjust the brightness corresponding to the second binding point grayscale of the first display area at the fourth brightness level to a difference with the target brightness that is less than a first preset difference, and obtain compensated display data or a compensation value during the adjustment process.

[0034] Step 204: Establish a corresponding relationship between the target brightness and the compensated display data or compensation value.

[0035] Step 205: adjust the third brightness level and / or the fourth brightness level to obtain a first corresponding relationship.

[0036] In order to obtain the first corresponding relationship, the third brightness level is first selected. The third brightness level is less than the first preset brightness level, and the brightness level of the second display area is less than the second preset brightness level (that is, the brightness level when not responding to the first instruction). Preferably, the first brightness level is the same as the second preset brightness level. Generally, below the first preset brightness level and below the second preset brightness level, EM dimming, that is, PWM dimming is used for dimming. DC dimming is used for dimming at the first preset brightness, and DC dimming is used above the third preset brightness level. Generally, a display panel has only one dimming method and only one brightness level, but there can also be multiple dimming methods and multiple brightness levels. Therefore, firstly, the actual brightness of the first display area of ​​the display panel at the first binding point grayscale value at the third brightness level is obtained, and the second binding point grayscale value at the fourth brightness level is obtained when the actual brightness is the same. Preferably, the third brightness level is multiple, preferably, the fourth brightness level is greater than or equal to 90nit, for example, the third brightness level can be 10nit, 5nit, 2nit, etc., and the fourth brightness level can be 90nit (the brightness level used for compression in DC dimming mode). Preferably, the number of first binding point grayscales is multiple, for example, the first binding point grayscale value can include at least five characteristic grayscale values, such as, the multiple characteristic grayscale values ​​at 10nit are 0, 32, 48, 115, 255, and correspondingly, in At the fourth brightness level, i.e. 90 nit, the second binding point grayscale value corresponding to the actual brightness of the first display area at the first binding point grayscale value when the first display area is at the third brightness level (in the PWM dimming mode, the actual brightness at this time is the original brightness corresponding to the first binding point grayscale value at the third brightness level plus the compensated brightness) is 0, 6, 8, 21, 44. Then, the actual brightness corresponding to the first binding point grayscale value of the first display area at the third brightness level is used as the target brightness, and the brightness corresponding to the second binding point grayscale of the first display area at the fourth brightness level is adjusted to a difference with the target brightness that is less than the first preset difference, and the compensated display data (the original brightness corresponding to the second binding point grayscale value at the fourth brightness level plus the compensation value) or the compensation value during the adjustment process is obtained. A correspondence between the target brightness and the compensated display data or compensation value can be established. Preferably, the fourth brightness level is greater than the third preset brightness level, the third brightness level includes multiple brightness levels (such as 10nit, 5nit, 2nit), and the fourth brightness level also includes multiple brightness levels (such as 90nit, 100nit). Each establishment process uses a third brightness level and a fourth brightness level, and the establishment process is repeated multiple times. The third brightness level and / or the fourth brightness level are adjusted in each establishment process. The first correspondence can be obtained by using interpolation and the correspondence between the target brightness and the compensated display data or compensation value at multiple third brightness levels.

[0037] Specifically, when establishing the corresponding relationship between the target brightness and the compensated display data or the compensation value, an interpolation method, such as a direct method, a Lagrange interpolation method, or a Newton interpolation method, may be used to establish the corresponding relationship.

[0038] Preferably, in the process of adjusting the brightness corresponding to the second binding point grayscale of the first display area at the fourth brightness level to a difference with the target brightness that is less than the first preset difference, each pixel included in the first display area can be adjusted separately so that the brightness corresponding to the second binding point grayscale of each pixel at the fourth brightness level is adjusted to a difference with the target brightness that is less than the first preset difference.

[0039] During the adjustment process, the chromaticity value corresponding to the second binding point grayscale of each pixel at the fourth brightness level can also be adjusted to a chromaticity difference with the chromaticity value corresponding to the first binding point grayscale of each pixel at the third brightness level that is less than the second preset difference.

[0040] Specifically, the original data is pixel voltage data, the display data is voltage data, the target brightness is determined according to the pixel voltage data, and the compensation value is a voltage compensation value.

[0041] The pixel voltage data includes display voltages corresponding to the three primary colors of light, and the compensation value is an adjustment value (offset) for adjusting the display voltages corresponding to the three primary colors of light, that is, a bias voltage. When compensating the first display area, the bias voltage of the display voltage corresponding to the three primary colors of light can be obtained through the first corresponding relationship, and the original data used for display by the pixels included in the first display area can be directly compensated.

[0042] It should be noted that the brightness difference can be adjusted by adjusting the display voltage of the green light (G) among the three primary colors, and the chromaticity difference can be adjusted by adjusting the display voltage of the red light (R) and the blue light (B) among the three primary colors.

[0043] Figure 4 is a schematic diagram of a display compensation device according to an embodiment of the present application. Figure 4 The display compensation device 400 includes: a determination module 401 and a compensation module 402 .

[0044] The determination module 401 is used to determine the compensated display data according to the original data of the first display area in response to the first instruction, wherein the first instruction includes an increase in the brightness of the second display area, and the brightness of the second display area after the increase is greater than the brightness of the first display area before responding to the first instruction, and the brightness level of the first display area before responding to the first instruction is less than a first preset brightness level.

[0045] The compensation module 402 is used to perform display compensation on the first display area according to the compensated display data, so that the brightness difference between the compensated first display area and the brightness of the first display area in the first state is less than a first preset difference, wherein the brightness level of the second display area in the first state is less than the second preset brightness level, and the display data of the first display area is the original data.

[0046] The display panel includes a first display area and a second display area. When receiving the first instruction, the brightness of the second display area will be increased so that the increased brightness of the second display area is greater than the brightness of the first display area before responding to the first instruction. At the same time, since the display panel does not have a low brightness problem when it is at a high brightness level, the brightness level of the first display area before responding to the first instruction is less than the first preset brightness level. At this time, the display data of the first display area is the original data. Due to the increase in the brightness of the second display area, the display mode of the screen has changed, switching from the previous PWM dimming mode to the DC dimming mode. At this time, the first display area can no longer use the compensation method in the previous dimming mode, so it is necessary to respond to the first instruction and obtain the compensated display data according to the original data of the first display area. The difference between the brightness of the first display area after displaying the first display area with the compensated display data and the brightness of the first display area in the first state is less than the first preset difference. It should be noted that the brightness level of the second display area in the first state is less than the second preset brightness level.

[0047] In an embodiment of the present application, by determining compensated display data based on the original data of the first display area when increasing the brightness of the second display area in response to the first instruction, and then performing display compensation on the first display area using the compensated display data, the brightness difference of the first display area before and after the brightness adjustment of the second display area can be made less than a first preset difference, thereby avoiding screen flickering.
