First, in an embodiment of the present application, a multi-view fusion compensation display method is provided, where an execution subject of the multi-view fusion compensation display method is a multi-view fusion compensation display device, and the multi-view fusion compensation display device is applied to a computer device, and the multi-view fusion compensation display method includes: acquiring a plurality of mura initial compensation tables corresponding to the display panel under a plurality of different visual angles, and obtaining the plurality of mura initial compensation tables; acquiring fusion coefficients corresponding to a plurality of different view angles when multi-view angle compensation data are fused, and obtaining a plurality of fusion coefficients; determining a corresponding mura fusion compensation value when multi-view compensation data are fused according to the multiple mura initial compensation tables and the multiple fusion coefficients; and carrying out brightness compensation on the display panel according to the mura fusion compensation value.
Fig. 2 is a schematic flow chart of an embodiment of a multi-view fusion compensation display method according to an embodiment of the present application, where the multi-view fusion compensation display method includes:
21. and acquiring the initial mura compensation tables corresponding to the display panel under a plurality of different visual angles to obtain a plurality of initial mura compensation tables.
In the embodiment of the application, different viewing angles exist when the picture of the display panel is viewed, so that the display panel corresponds to different mura compensation values under different viewing angles; in the embodiment of the application, the compensation is performed by combining different compensation values corresponding to different viewing angles, so that the compensation is performed only under a certain viewing angle, and the mura problem still exists under other viewing angles.
Since the actual display panel includes a plurality of pixels, usually, each pixel needs to be compensated, a plurality of mura initial compensation tables corresponding to different viewing angles are actually obtained, and one viewing angle corresponds to one mura initial compensation table; each mura initial compensation table comprises a compensation value corresponding to each pixel point. And in general, for the same pixel point, the mura compensation values corresponding to different mura initial compensation tables may be the same or different.
Fig. 3 is a schematic diagram of an embodiment of a mura initial compensation table corresponding to a main view angle according to an embodiment of the present application. In the embodiment shown in fig. 3, the mura initial compensation table includes 4*4 initial compensation values, where (1, 1) - (4, 4) are coordinates of each pixel point, each pixel point corresponds to one compensation value, and a specific size of the initial compensation value corresponding to each pixel point can be calculated.
In the embodiment of the present application, before obtaining the mura initial compensation tables corresponding to the display panel under the multiple different viewing angles, the display panel may be further divided into the first number of fusion units. The multi-view fusion compensation display method provided by the embodiment of the application can be utilized to compensate only partial fusion units, especially partial fusion units located in the edge area; all fusion units can also be compensated simultaneously.
The number of the pixels in each fusion unit in the first number of fusion units is the same, and the pixels in each fusion unit are arranged in a manner of n×n, where n is a positive integer greater than or equal to 1. I.e. each of the first number of fusion units comprises n x n pixel points.
In some embodiments, the display panel may be divided into 3*3 fusion units, and the pixels in each of the 3*3 fusion units are also arranged in n×n manner; in other embodiments, the display panel may be divided into a number of fusion units such as 4*4 or 5*5. That is, the plurality of pixel points in the fusion unit are all arranged in a square manner.
22. And acquiring fusion coefficients corresponding to a plurality of different view angles when the multi-view compensation data are fused, so as to obtain a plurality of fusion coefficients.
23. And determining a corresponding mura fusion compensation value during multi-view compensation data fusion according to the multiple mura initial compensation tables and the multiple fusion coefficients.
In the embodiment of the application, the mura initial compensation tables corresponding to the multiple view angles are required to be fused, and the pixel points are compensated by using the fused mura fusion compensation values obtained after fusion. When determining the mura fusion compensation values, the fusion coefficients corresponding to the initial mura compensation tables of each view angle need to be determined, so that the mura fusion compensation values are determined by combining the fusion coefficients.
24. And carrying out brightness compensation on the display panel according to the mura fusion compensation value.
According to the multi-view fusion compensation display method, firstly, a plurality of mura initial compensation tables corresponding to the display panel under different view angles are obtained, fusion coefficients corresponding to the different view angles are respectively obtained, then fusion is carried out on the plurality of mura initial compensation tables under the different view angles according to the fusion coefficients, a fused mura fusion compensation value is obtained, and finally brightness compensation is carried out on the display panel by utilizing the fused mura fusion compensation value. According to the method and the device, the corresponding mura initial compensation tables under different visual angles are fused through the fusion coefficients, and the display panel is subjected to brightness compensation by utilizing the mura fusion compensation values obtained by fusing the compensation values under the different visual angles, so that the mura problem under the different visual angles can be effectively reduced. As shown in fig. 4, an embodiment of determining a plurality of fusion coefficients according to the embodiment of the present application may include:
41. and acquiring a preset fusion coefficient formula.
42. And obtaining a plurality of initial fusion coefficients according to the number of the plurality of mura initial compensation tables.
43. And adjusting the plurality of initial fusion coefficients according to the first quantity to obtain a plurality of fusion coefficients.
In the embodiment of the present application, the preset fusion coefficient formula may be a preset gaussian formula including a normalization factor. The number of the mura initial compensation tables is plural, and in this application, the mura initial compensation tables are required to be used for compensation, so that each mura initial compensation table needs to correspond to one fusion coefficient. Therefore, the first number of values may be substituted into a preset gaussian equation including the normalization factor, to obtain a plurality of fusion coefficients.
In one particular embodiment, the gaussian equation including the normalization factor may be:
G(x,y)＝K*exp(-((x^2+y^2)/2σ^2))
wherein the parameter K is a normalization factor, and the following conditions are satisfied:
∫∫G(x，y)dxdy＝1
in the embodiment of the present application, when dividing the fusion unit or the fusion unit, the division may be performed according to a×b criteria; and in the actual partitioning process, the values of a and b are typically equal. The first number or the second number is the value of a x b. Therefore, substituting the first quantity into a preset fusion coefficient formula, a and b can be respectively used as the values of x and y, and sigma is a parameter in a Gaussian formula; thereby calculating a plurality of initial fusion coefficients.
The initial fusion coefficients at this time represent only fusion that can be performed using the initial compensation tables of the mura. However, the initial fusion coefficients only represent the ratio of the initial mura compensation tables when fusion is performed, and do not represent the respective fusion coefficient of each fusion unit. Therefore, a plurality of initial fusion coefficients are also required to be adjusted according to the first quantity, so as to obtain a plurality of fusion coefficients.
In one embodiment, the plurality of mura initial compensation tables may be five mura initial compensation tables, and then the corresponding initial fusion coefficients are five. For example, respectively: 1/8, 4/8, 1/8. But five initial fusion coefficients also need to be adjusted. When the number of the fusion units is 4*4, the adjusted fusion coefficients are respectively: 1/16, 2/16, 4/16, 2/16, 1/16.
It should be noted that the above-mentioned multiple fusion coefficients only represent the ratio of the initial compensation table of each mura to the size occupied by the fusion. Nine fusion coefficients are provided because, during actual fusion, adjacent partial fusion units correspond to the same initial compensation table, and the proportion occupied by the initial compensation table during fusion increases.
After determining the plurality of fusion coefficients, a corresponding mura fusion compensation value in the multi-view compensation data fusion process can be determined according to the plurality of mura initial compensation tables and the plurality of fusion coefficients. As shown in fig. 5, an embodiment of determining mura fusion compensation values according to the embodiments of the present application may include:
51. and obtaining a mapping relation between a plurality of preset mura initial compensation tables and a fusion unit.
In the embodiment of the present application, since each mura initial compensation table includes a compensation value for compensating all the pixel points in the display panel, in the embodiment of the present application, the display panel is compensated by using a plurality of mura initial compensation tables, and in fact, different pixel points are compensated by directly using part of the compensation values in different mura initial compensation tables.
The method specifically comprises the following steps: for some pixels, compensation values corresponding to one mura initial compensation table can be used for compensation, and for other pixels, compensation values corresponding to another different mura initial compensation table can be used for compensation, so that compensation is performed by combining a plurality of mura initial compensation tables.
Therefore, in the embodiment of the present application, there is a mapping relationship between the plurality of mura initial compensation tables and the fusion unit. Since there are a plurality of mura initial compensation tables, the mapping relation is actually representative of which mura initial compensation table should be used when determining the first mura compensation value corresponding to a certain fusion unit.
52. And determining fusion coefficients corresponding to the multiple mura initial compensation tables respectively according to the mapping relation.
After the mapping relation is obtained, a mura fusion compensation value corresponding to the multi-view compensation data fusion can be determined according to the mapping relation and the fusion coefficients. Firstly, determining fusion coefficients corresponding to a plurality of mura initial compensation tables according to a mapping relation.
In general, the human eyes watch the display panel from the main viewing angle in most cases, so the display panel picture under the positive viewing angle is mainly compensated. Then when the compensation data is fused, the mura initial compensation table of the main view angle is also used as the main; i.e. the fusion coefficient of the mura initial compensation list corresponding to the main view angle is the largest. And the same can determine the fusion coefficients corresponding to other mura initial compensation tables.
53. And determining a mura fusion compensation value corresponding to the multi-view compensation data fusion according to the fusion coefficients corresponding to the mura initial compensation tables.
After determining the corresponding fusion coefficients of the mura initial compensation tables, the read mura initial compensation tables can be fused to obtain mura fusion compensation values. The method comprises the following steps: taking any fusion unit in the plurality of fusion units as a target fusion unit, and determining a target fusion coefficient corresponding to the target fusion unit; according to the mapping relation and the target fusion coefficient, determining a target mura corresponding to the target fusion unit, and determining a target mura initial compensation table corresponding to the target fusion unit according to the mapping relation; taking any fusion unit as a target fusion unit to obtain target mura initial compensation tables corresponding to the fusion units respectively, and obtaining a plurality of target mura initial compensation tables; and according to the mapping relation, fusing a plurality of target mura initial compensation tables to obtain mura fusion compensation values.
Specifically, the target fusion coefficient corresponding to the target fusion unit in the present application actually represents the ratio of the target mura initial compensation table corresponding to the target fusion unit occupied during fusion. When the fusion is actually carried out, a target mura initial compensation table corresponding to the target fusion unit is determined according to the mapping relation, so that a target mura initial compensation value corresponding to the target fusion unit is directly determined according to the target mura compensation table.
Fig. 6 is a schematic diagram of multiple viewing angles according to an embodiment of the present application. In the embodiment shown in fig. 6, the display panel can be viewed from five different viewing angles, respectively: a positive viewing angle, a left viewing angle, an up viewing angle, a right viewing angle, and a down viewing angle. The display panel also corresponds to five different mura initial compensation tables, namely a mura initial compensation table LUT1 corresponding to a front view angle, a mura initial compensation table LUT2 corresponding to a left view angle, a mura initial compensation table LUT3 corresponding to an upper view angle, a mura initial compensation table LUT4 corresponding to a right view angle and a mura initial compensation table LUT5 corresponding to a lower view angle.
Fig. 7 is a schematic diagram of an embodiment of a fusion unit according to an embodiment of the present application. In the embodiment shown in fig. 7, the display panel is divided into 4*4 fusion units. The fusion coefficient calculated at this time may be:
FIG. 8 is a diagram showing an embodiment of mura fusion compensation values according to the present embodiment; how the multi-view fusion compensation method provided in the present application performs compensation is described herein with reference to fig. 3, 7, and 8. In some embodiments, five mura initial compensation tables are respectively LUT1-LUT5, and each mura initial compensation table is shown in fig. 3, and includes a compensation value corresponding to each pixel point; only the compensation values for the same pixel point in the different mura initial compensation tables are not exactly the same.
In the embodiment of the application, five mura initial compensation tables are fused to compensate the display panel at the same time, namely 4*4 fusion units are compensated by using the five mura initial compensation tables at the same time. And the mapping relation is artificially defined according to the actual view angle situation. For example, when determining the first mura compensation value, the upper partial partition needs to use the initial mura compensation table LUT3 corresponding to the upper viewing angle; instead of using the mura initial compensation tables corresponding to the left view, or the right view, or the lower view. According to the mapping relation, the mura initial compensation table corresponding to the fusion unit can be directly determined. Taking fig. 7 as an example, two fusion units located at the uppermost and middle positions correspond to the mura initial compensation table LUT3 of the upper view angle.
After determining the mura initial compensation list corresponding to each fusion unit by using the mapping relation, a specific first mura compensation value corresponding to the fusion unit needs to be determined in the corresponding mura initial compensation list. At this time, it is necessary to determine the position of the fusion unit in the display panel and find the compensation value at the corresponding position in the corresponding mura initial compensation table as the first mura compensation value.
Referring to fig. 3, 7 and 8, taking the pixel point 4*4 in the upper left corner of the display panel as an example in fig. 3, 7 and 8, the compensation values corresponding to the 16 pixel points with coordinates (1, 1) - (4, 4) are stored in fig. 3. According to the mapping relation, a mura initial compensation table LUT1 of which the coordinate is (1, 1) and the pixel point corresponds to the main visual angle can be determined; then the compensation value corresponding to the pixel with coordinates (1, 1) in the mura initial compensation table LUT1 can be found as the target mura initial compensation value corresponding to the fusion unit. And the pixel point with coordinates (1, 2) corresponds to the mura initial compensation table LUT3 of the upper view angle, then the compensation value corresponding to the pixel point with coordinates (1, 2) should be searched in the mura initial compensation table LUT3 of the upper view angle as the target mura initial compensation value corresponding to the fusion unit.
By using the method, the first mura compensation value corresponding to each fusion unit in 4*4 fusion units can be respectively determined, so as to obtain 4*4 target mura initial compensation values; and 4*4 mura initial compensation values come from five mura initial compensation tables, so as to realize the integration of the mura initial compensation tables of different visual angles. Meanwhile, the pixel point can be used as the minimum fusion unit in the embodiment of the application, so that the problem of mura under different visual angles can be effectively avoided on the basis of fusing initial mura compensation tables of different visual angles.
