In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described.

It will be understood by those skilled in the art that mura compensation is the grayscale value by changing each pixel, it is bright for showing It spends relatively high pixel and applies lower grayscale value, the pixel relatively low for display brightness applies higher grayscale value, with reality The uniformity of existing picture brightness.However, the prior art will not be able to satisfy actual compensation when luminance difference is anisotropic larger in picture Demand shows that the compensation effect of screen mura is poor.To solve the above-mentioned problems, the present embodiment provides a kind of compensation of display brightness Method, apparatus, equipment and storage medium are applied to LCD technology.Wherein, the display brightness compensation method of the present embodiment can To be executed by the existing brightness disproportionation compensation device in Figure 1A, can also be executed by other compensation devices, the present embodiment is to this Without limitation.

In the following, being to execute with the existing brightness disproportionation compensation device (abbreviation compensation device) in Figure 1A for ease of description The specific implementation process of the display brightness compensation method of the present embodiment is described in detail in main body.

Fig. 2 is the flow diagram of display brightness compensation method provided by the invention.As shown in Fig. 2, the present embodiment is aobvious Show that luminance compensation method may include:

S101, the brightness for obtaining each block of pixels in target area.

Specifically, compensation device can use the shooting modules filmed display screen such as camera.Compensation device can be chosen aobvious The all or part of of display screen curtain is used as target area, can also be according to the part for needing mura to compensate in display screen as mesh Mark region, the present embodiment to the specific implementation form of target area without limitation.

It further, include multiple block of pixels in target area, each block of pixels can be by one or more pixel structures At.Wherein, the present embodiment to the pixel quantity of the quantity of block of pixels and each block of pixels all without limitation.

On the one hand, when only including a pixel in each block of pixels, since grayscale value size may indicate that bright dark journey Degree, therefore, the brightness of any pixel block can be indicated using the grayscale value of the pixel, i.e., compensation device can obtain mesh Mark the corresponding grayscale value of each pixel in region.Wherein, the present embodiment is to the specific of the average gray-scale value of any pixel block Realization process is without limitation.It, can be right respectively to each pixel in the block of pixels in the present embodiment for any pixel block The grayscale value answered carries out summation operation, obtains the sum value, then takes average gray-scale value of the average value of this and value as the block of pixels.This It, can also be using the corresponding grayscale value of the pixel in the geometric center of the block of pixels as the average ash of the block of pixels in embodiment Rank value.In the present embodiment, the corresponding grayscale value of pixel that required supplementation in the block of pixels can also be subjected to summation fortune It calculates, obtains the sum value, then take average gray-scale value of the average value of this and value as the block of pixels.

On the other hand, when in each block of pixels including multiple pixels, since grayscale value size may indicate that bright dark journey Degree, therefore, the brightness of any pixel block can be indicated using average gray-scale value, i.e., compensation device can obtain target area In the corresponding average gray-scale value of each block of pixels.

In the present embodiment, compensation device can introduce the pixel needed not compensate for wherein when determining target area, To include when needing the pixel compensated and the pixel needed not compensate in each block of pixels, compensation device is available The brightness for the pixel for needing to compensate in each block of pixels;By calculating the pixel brightness for needing to compensate in each block of pixels Average value obtains the brightness of each block of pixels.

Further, in actual application, compensation device can directly determine the region for needing luminance compensation, because This, compensation device can only include the pixel for needing to compensate in the target area when determining target area, thus, each When only including the pixel for needing to compensate in block of pixels, all pixels point is bright in the available each block of pixels of compensation device Degree;By calculating the average value of all pixels point brightness in each block of pixels, the brightness of each block of pixels is obtained.

S102, according to the brightness of each block of pixels, initial Benchmark brightness is adjusted, and bright according to benchmark adjusted The brightness of degree and each block of pixels, calculates the target compensation data of each block of pixels, wherein target compensation data are in scheduled compensation model In enclosing.

Specifically, compensation device can use various ways, by the brightness of each block of pixels, to initial Benchmark brightness into Row adjustment.Wherein, initial Benchmark brightness can be determined by showing the bit rate of screen in display equipment, specifically can root It is determined according to empirical value.Under normal circumstances, display screen uses 10bit, and initial Benchmark brightness can be indicated with grayscale value 900. In the following, being carried out to compensation device to the detailed process that initial Benchmark brightness is adjusted using two kinds of feasible embodiments detailed It describes in detail bright.

In a kind of feasible specific embodiment, optionally, according to the brightness of each block of pixels, brightness in target area is determined Maximum value and minimum value;According to maximum value and minimum value, initial Benchmark brightness is adjusted.

Specifically, compensation device can be maximized and minimum value from the brightness of each block of pixels, as in target area The maximum value and minimum value of brightness.For example, including three block of pixels, respectively block of pixels 1, block of pixels 2 and picture in target area The brightness of plain block 3, block of pixels 1 can indicate that the brightness of block of pixels 2 can be indicated with grayscale value 1000, pixel with grayscale value 800 The brightness of block 3 can indicate with grayscale value 700, due to 1000 > grayscale value of grayscale value, 800 > grayscale value 700, ash can be chosen Rank value 1000 is used as maximum value, and grayscale value 700 is used as minimum value.

Further, compensation device can be according to the average value of the sum of maximum value and minimum value, to adjust initial benchmark Brightness.For example, minimum value is grayscale value 700, and initial Benchmark brightness can use grayscale value when maximum value is grayscale value 1000 900 when indicating, the average value of the sum of grayscale value 1000 and grayscale value 700 is 850, then regard average value 850 as base adjusted Quasi- brightness adjusts initial Benchmark brightness.

In another feasible specific embodiment, according to the brightness of each block of pixels and initial Benchmark brightness, obtain each The initial compensation data of block of pixels;According to the maximum value and minimum value in the initial compensation data of each block of pixels, to initial base Quasi- brightness is adjusted.

Specifically, compensation device can be made with initial Benchmark brightness poor respectively with the brightness of each block of pixels, obtain each picture The initial compensation data of plain block.For example, including three block of pixels, respectively block of pixels 1, block of pixels 2 and pixel in target area The brightness of block 3, block of pixels 1 can indicate that the brightness of block of pixels 2 can be indicated with grayscale value 1000, block of pixels with grayscale value 800 3 brightness can indicate that initial Benchmark brightness can indicate that then block of pixels 1 is initial with grayscale value 900 with grayscale value 700 Offset data is grayscale value -100 grayscale value 800- grayscale value 900=, and the initial compensation data of block of pixels 2 are grayscale value 1000- Grayscale value 900=grayscale value 100, the initial compensation data of block of pixels 3 are grayscale value 700- grayscale value 900=grayscale value -200.

Further, compensation device can choose maximum value and minimum value in the initial compensation data of each block of pixels, then The average value for calculating the sum of maximum value and minimum value, is adjusted initial Benchmark brightness further according to the average value.For example, picture The initial compensation data of plain block 1 are grayscale value -100, and the initial compensation data of block of pixels 2 are grayscale value 100, block of pixels 3 just Beginning offset data is grayscale value -200, and initial Benchmark brightness can be indicated with grayscale value 900, due to 100 > grayscale of grayscale value It is worth -100 > grayscale value -200, therefore, grayscale value 100 can be chosen as maximum value, grayscale value -200 is used as minimum value, grayscale value 100 and the average value of the sum of grayscale value -200 be -50, then the sum of averaged -50 and grayscale value 900 are grayscale value 850, i.e., Grayscale value 850 will adjust initial Benchmark brightness as Benchmark brightness adjusted.

Further, compensation device can be according to the average value of the sum of maximum value and minimum value, to adjust initial benchmark Brightness.For example, minimum value is grayscale value 700 when maximum value is grayscale value 1000, when initial Benchmark brightness is grayscale value 900, The average value of the sum of grayscale value 1000 and grayscale value 700 is 850, then adjusts average value 850 as Benchmark brightness adjusted Whole initial Benchmark brightness.

In a specific embodiment, when the brightness being scaled the brightness under 8bit under 10bit, with compensation device The brightness of multiple block of pixels under the 8bit got, each block of pixels are a BlockSize of 8*8 pixel, each pixel The brightness of block indicates with average gray-scale value, for the initial Benchmark brightness under 10bit is grayscale value 900, respectively to existing skill The specific implementation process of art and the method for the present embodiment is illustrated.

In the prior art, the average gray-scale value of each block of pixels is subtracted into grayscale value 900, obtains the difference of each block of pixels Value, further according to the difference of each block of pixels, the offset data of available each block of pixels.For ease of description, include in table 1 Four column, first is classified as the average gray-scale value of each block of pixels.Second is classified as initial Benchmark brightness, i.e. grayscale value 900.Third column For the difference of each block of pixels, wherein the difference of each block of pixels is indicated with grayscale value.4th is classified as the compensation of each block of pixels Data, wherein the offset data of each block of pixels is indicated with grayscale value.

Table 1

In the present embodiment, based on the data in table 1, compensation device can obtain most according to the difference of each block of pixels Big value is grayscale value 101, and minimum value is grayscale value -150, and the average value of the sum of maximizing and minimum value is grayscale value -24.5, Being rounded is grayscale value -25.Grayscale value -25 and grayscale value 900 are summed again, the Benchmark brightness after being adjusted is grayscale value 875. It for ease of description, include four column in table 2, first is classified as the average gray-scale value of each block of pixels.Second is classified as base adjusted Quasi- brightness, i.e. grayscale value 875.Third is classified as the offset data of each block of pixels, wherein the offset data ash of each block of pixels Rank value indicates.

Table 2

Due to mura offset data range be under 10bit between ± 127 grayscale value ranges, when difference- When within the scope of 127 grayscale values and+127 grayscale values, De-mura module 13 is read in compensation device offset data and difference one Sample.When difference is less than grayscale value -127, the offset data that De-mura module 13 is read in compensation device is grayscale value -127; When difference is greater than grayscale value+127, the value that De-mura module 13 is read in compensation device is grayscale value+127.Therefore, it is mending When repaying data not within the scope of ± 127 grayscale values, compensation device can not compensate correct grayscale value, cause compensation effect bad.

Further, in the prior art, the offset data as grayscale value 750 is compensated in table 1 has obviously exceeded compensation Range.And in the present embodiment, if each block of pixels is compensated in table 2 offset data is obviously all in compensation range.

S103, the target compensation data according to each block of pixels, compensate the brightness of each block of pixels.

Specifically, compensation device can be calculated according to the brightness of Benchmark brightness adjusted and each block of pixels pre- The target compensation data of each block of pixels in fixed compensation range.Due to initial Benchmark brightness be those skilled in the art according to Experience confirmation, therefore, the prior art just can not be in view of display screen it is possible that the anisotropic biggish problem of luminance difference, holds Easily reduce compensation effect.And the method that the present embodiment uses is bright to initial benchmark by the initial data for being shown in display screen Degree is adjusted, and obtains the Benchmark brightness adjusted suitable for current display screen, can be according to Benchmark brightness adjusted With the brightness of each block of pixels, the target compensation data of each block of pixels are calculated.When to show that screen is shown again, compensating module The brightness of each block of pixels can precisely be compensated according to the target compensation data of accurate each block of pixels, so that display screen Brightness it is more uniform.

In addition, compensation device can also be according to the bright of target area when target area is to show the partial region of screen It is slotting to show that the brightness in other regions in screen carries out by interpolation method for degree, i.e., the grayscale value of each block of pixels in target area Value complement is repaid.Wherein, the detailed process of interpolation can be found in detailed process in the prior art, be not repeated herein.
