In recent years, with the popularization of 4K and 2K televisions, the phenomenon of panel brightness unevenness becomes more serious, and a Demura (panel brightness unevenness elimination) technology is developed, and at present, in order to reduce the data amount of compensation, the technology adopts a scheme of setting a minimum compensation area, for example, a rectangular area with 8 × 8 to 64 pixels (pixels) which is commonly used at present is the minimum compensation area, only 4 right-angle points of the rectangle are taken as reference points for compensation, and other areas of the rectangle are obtained by using the 4 points as reference points for arithmetic operation, so that a memory only needs to store data of4 pixels per point.

As shown in fig. 1, which is a sampling schematic diagram for eliminating the panel brightness unevenness at present, a camera of a system for eliminating the panel brightness unevenness shoots the display condition of the whole panel, a picture on the left side in the diagram indicates that there are a white block panel brightness unevenness W and a black block panel brightness unevenness B in the horizontal direction, and data compensation is performed on two areas after analysis and calculation for eliminating the panel brightness unevenness, that is, the display data of the area is the addition of the original data and the compensation data, the compensation data of the white block panel brightness unevenness W is a negative number, that is, the display data is reduced a little, and the data corresponding to the black block panel brightness unevenness B is increased a little correspondingly, so that the uniform brightness can be obtained finally, and the elimination of the panel brightness unevenness is realized.
As shown in fig. 2, the schematic diagram of the uneven brightness of the panel at the vertical boundary of the substrate is shown, and as the size of the panel is larger and the number of the substrates is larger and larger, and the input voltage of the substrate has slight deviation, the display effect of the area driven by the substrate will be different from that of other areas, and the uneven brightness of the panel will appear visually. In the figure, a high resolution panel UD with 3840 × 2160 pixels is taken as an example, there are 12 substrates COF1 to COF12, the number of pixels for driving each substrate is 3840/12 to 320, and it is assumed that the driving area corresponding to the substrate COF4 is dark.
As shown in fig. 3, since the existing technology for eliminating the uneven brightness of the panel generally uses a unit of 8 × 8 pixels as the minimum compensation unit, the dots in the figure are sampling points, and since the number of the substrates is even, the number of the driving lines of each substrate is a multiple of 8 for 12 substrates of the high resolution panel, except for the first substrate, the first driving lines of other substrates are not on the sampling points, and the dividing line between the substrate COF3 and the substrate COF4 in the figure is enlarged, wherein reference numeral 960 is the last driving line of the substrate COF3, reference numeral 961 is the first driving line of the substrate COF4, reference numeral 960 is a sampling point, and reference numeral 961 is not on the sampling points, although the 968 th driving line is still on the sampling point, the linear operation of data from reference numeral 960 to the sampling point of the reference numeral 968 cannot perfectly eliminate the phenomenon of the first driving line, the visual panel brightness non-uniformity phenomenon still exists.
Therefore, the present application provides a method for solving the boundary panel brightness unevenness of the substrate and improving the adaptability of the panel brightness unevenness elimination mechanism to the panel, as described below.
FIG. 4 is a flowchart of a method for eliminating non-uniformity of panel brightness between horizontal and vertical substrates according to the present application; fig. 5 is a schematic diagram of obtaining a plurality of demarcation points of a demarcation line of a substrate in a vertical direction according to an embodiment of the present application.
Referring to fig. 4 to 5, a method for eliminating panel brightness non-uniformity between horizontal and vertical substrates according to an embodiment of the present invention includes the following steps:
in step S1, a plurality of boundary points P1 and P2 are set at the boundaries of a plurality of substrates (for example, chip on film) COF3 and COF4 in the vertical direction to be subjected to complementary imaging.
In the embodiment of the present application, a computer or other computing device may be used to implement the setting operation, as shown in fig. 2, the number of driving lines of each substrate COF1 to COF12 is a multiple of 8, and then the first driving lines of other substrates COF2 to COF12 are not located at sampling points except for the first substrate COF1, and when the boundary between the substrate COF3 and the substrate COF4 in fig. 2 is enlarged, as shown in fig. 3, reference numeral 960 is the last driving line of the substrate COF3, and reference numeral 961 is the first driving line of the substrate COF4, reference numeral 960 is a sampling point, and reference numeral 961 is not located at a sampling point, so that a plurality of boundary points of the boundary lines of the plurality of substrate COF2 to the first driving line of the substrate COF12 in the vertical direction that needs to be compensated for photographing are set by a computer, as shown in fig. 5, a plurality of boundary points P1 and P2 of the boundary points of the boundary lines of the first driving line, in the embodiment of the present invention, the boundary of the substrate to be subjected to the complementary photographing may be obtained through a general mathematical calculation (as illustrated in fig. 2 by the high resolution panel UD of 3840 × 2160 pixels, the number of driving lines of each of the substrates COF1 to COF12 is a multiple of 8, so that a plurality of boundary points of the boundaries of the first driving lines of the plurality of substrates COF2 to COF12 are subjected to the complementary photographing), or the boundary of the substrate on the panel may be obtained through a luminance obtaining device (camera) to identify the boundary of the substrate to be subjected to the complementary photographing.
Step S2, a panel is photographed to obtain brightness values of a plurality of sampling points.
In the embodiment of the present application, a computing device such as a computer may control a brightness obtaining device (e.g., a camera) to shoot a panel to obtain brightness values of a plurality of sampling points, where the plurality of sampling points include: right-angled points N1 to N4 (N1 to N4 shown in fig. 5 and dots shown in fig. 3 are sampling points) of a plurality of rectangular regions of the panel, and a plurality of boundary points P1 and P2 of a boundary line of a substrate COF4 to be additionally photographed, wherein the boundary points P1 and P2 are arranged on the boundary line at intervals of 8 pixels to form one boundary point P1 and P2 (the boundary line of the substrate COF4 shown in fig. 5, the boundary line of the substrate COF2 shown in fig. 2 (reference numeral 321), the boundary line of the substrate COF3 (reference numeral 641), and the like, are additionally photographed to obtain luminance values of the plurality of boundary points of the boundary line of the substrate COF 3).
And step S3, outputting the brightness values of the plurality of right-angle points N1-N4 and the brightness values of the plurality of demarcation points P1 and P2.
In the embodiment of the present invention, the luminance values of the plurality of right-angle points N1-N4 (the luminance values of N1-N4 shown in fig. 5 and the luminance values of dots shown in fig. 3) and the luminance values of the plurality of dividing points P1 and P2 (the luminance values of the dividing points P1 and P2 of the dividing line of the substrate COF4 shown in fig. 5, and the luminance values of the plurality of dividing points such as the dividing line (reference numeral 321) of the substrate COF2 and the dividing line (reference numeral 641) of the substrate COF3 shown in fig. 2) can be output to a computer or other computing device for subsequent data operation processing.
And step S4, calculating compensation values of the brightness values of the plurality of right-angle points N1-N4 and the brightness values of the plurality of demarcation points P1 and P2.
In the embodiment of the present application, compensation values may be calculated for the luminance values of the plurality of right angle points N1 to N4 (the luminance values of N1 to N4 shown in fig. 5 and the luminance values of dots shown in fig. 3) and the luminance values of the plurality of dividing points P1 and P2 (the luminance values of the dividing points P1 and P2 of the dividing line of the substrate COF4 shown in fig. 5 and the luminance values of the plurality of dividing points such as the dividing line (reference numeral 321) of the substrate COF2 and the dividing line (reference numeral 641) of the substrate COF3 shown in fig. 2) by using a computer or other computing device.
Therefore, the first driving lines of the substrates COF2 to COF12 are also sampled in the embodiments of the present application, so that if the boundary brightness unevenness occurs, the correct compensation value can be obtained because the initial boundary of the panel brightness unevenness is also at the sampling point, and the compensation value of the 8 th driving line is also correct, so that the whole panel brightness unevenness region can be well compensated, and the substrate boundary brightness unevenness can be well eliminated. Meanwhile, because only the sampling operation is added to the first driving line of each substrate, for 12 substrates of the panel UD, the sampling point of the conventional demura technology is 481 (horizontal) X271 (vertical) which is 130351 points (as shown in fig. 3), while the embodiment of the present application only adds 11 sampling lines, i.e. 271X11 which is 2981 points, which is only 2.3% more data amount than the original, so that there is no great burden on the calculation amount and the final data storage amount. Similarly, the method can also be used for effectively solving the problem that the panel brightness is not uniform in the horizontal direction.
In some embodiments, the obtained rectangular areas of the panel may be 8 × 8 pixels or 4 × 4 pixels, and the boundary points of the substrates COF2 to COF12 are obtained at intervals of 8 or 4 pixels on the boundary line, so that a user can adjust the precision of the sampling points required by the luminance obtaining device according to the size of the panel and the number of the substrates.
In an embodiment, a method for eliminating panel brightness non-uniformity between horizontal and vertical substrates according to the embodiments of the present disclosure may be applied to an LCD display panel, an OLED display panel, a QLED display panel, a curved display panel, or other display panels. For example: referring to fig. 4 to 5, the method for eliminating the brightness unevenness of the LCD display panel between the horizontal and vertical substrates according to the present embodiment includes the following steps:
in step S1, a plurality of boundary points P1 and P2 are set at which the boundaries of a plurality of substrates (e.g., chip on film) COF3 and COF4 in the vertical direction of the LCD panel need to be compensated for.
In the embodiment of the present application, a computer or other computing device may be used to perform the above setting operation, as shown in fig. 2, the number of driving lines of each of the substrate COFs 1 to COF12 is a multiple of 8, and then the first driving lines of the other substrates COF2 to COF12 are not located at sampling points except the first substrate COF1, and when the boundary between the substrate COF3 and the substrate COF4 in fig. 2 is enlarged, as shown in fig. 3, reference numeral 960 is the last driving line of the substrate COF3, and reference numeral 961 is the first driving line of the substrate COF4, reference numeral 960 is a sampling point, and reference numeral 961 is not located at a sampling point, so that the computer is used to set the boundary points of the boundary lines of the first driving lines of the plurality of substrate COF2 to COF12 in the vertical direction of the LCD display panel to be subjected to complementary photographing, and as shown in fig. 5, the computer is used to set the boundary points P1 of the boundary points of the first driving lines of the, P2, in the embodiment of the present application, the boundary of the substrate to be subjected to the additional photographing can be obtained through a general mathematical calculation (as illustrated in fig. 2 by the LCD display panel UD with 3840 × 2160 pixels, the number of the driving lines of each of the substrates COF1 to COF12 is a multiple of 8, so that a plurality of boundary points of the boundaries of the first driving lines of the plurality of substrates COF2 to COF12 are subjected to the additional photographing), or the boundary of the substrate on the LCD display panel is obtained by a luminance obtaining device (camera) to identify the boundary of the substrate to be subjected to the additional photographing.
Step S2, a video image of the LCD panel is captured to obtain brightness values of a plurality of sampling points.
In the embodiment of the present application, a computing device such as a computer may be used to control a brightness obtaining device (e.g., a camera) to capture a video image of an LCD display panel to obtain brightness values of a plurality of sampling points, where the plurality of sampling points include: the LCD panel includes rectangular regions N1 to N4 (N1 to N4 shown in fig. 5 and dots shown in fig. 3 are sampling points) at right angles in a plurality of rectangular regions, and a plurality of boundary points P1 and P2 at which a boundary of a substrate COF4 to be photographed is to be complemented, wherein the boundary points P1 and P2 are complementary to each other by taking one boundary point P1 and P2 at intervals of 8 pixels on the boundary (the boundary of a substrate COF4 shown in fig. 5, the boundary of the substrate COF2 shown in fig. 2 (reference numeral 321), the boundary of the substrate COF3 (reference numeral 641), and the like, and can be complemented to photograph to obtain luminance values at the plurality of boundary points at the boundary of the substrate.
And step S3, outputting the brightness values of the plurality of right-angle points N1-N4 and the brightness values of the plurality of demarcation points P1 and P2.
In the embodiment of the present application, the luminance values of the plurality of right-angle points N1-N4 (the luminance values of N1-N4 shown in fig. 5 and the luminance values of dots shown in fig. 3) and the luminance values of the plurality of dividing points P1 and P2 (the luminance values of the dividing points P1 and P2 of the dividing line of the substrate COF4 shown in fig. 5, and the luminance values of the plurality of dividing points such as the dividing line (reference numeral 321) of the substrate COF2 and the dividing line (reference numeral 641) of the substrate COF3 shown in fig. 2) can be output to a computer or other computing device, so as to facilitate subsequent operation.
And step S4, calculating compensation values of the brightness values of the plurality of right-angle points N1-N4 and the brightness values of the plurality of demarcation points P1 and P2.
In the embodiment of the present application, compensation values may be calculated by using a computer or other computing device to calculate the luminance values of the plurality of right angle points N1 to N4 (the luminance values of N1 to N4 shown in fig. 5 and the luminance values of dots shown in fig. 3) and the luminance values of the plurality of dividing points P1 and P2 (the luminance values of the dividing points P1 and P2 of the dividing line of the substrate COF4 shown in fig. 5 and the luminance values of the plurality of dividing points such as the dividing line (reference numeral 321) of the substrate COF2 and the dividing line (reference numeral 641) of the substrate COF3 shown in fig. 2).
Therefore, the first driving lines of the substrates COF2 to COF12 are also sampled in the embodiment of the present application, so that if the boundary brightness unevenness occurs, since the starting boundary of the LCD display panel brightness unevenness is also at the sampling point, the correct compensation value can be obtained, and the compensation value of the 8 th driving line is also correct, the whole LCD display panel brightness unevenness region can be well compensated, and the substrate boundary brightness unevenness can be well eliminated. Meanwhile, because only the sampling operation is added to the first driving line of each substrate, for 12 substrates of the LCD display panel UD, the sampling point of the conventional demura technique is 481 (horizontal) X271 (vertical) which is 130351 points (as shown in fig. 3), while the embodiment of the present application only adds 11 sampling lines, i.e. 271X11 which is 2981 points, which is only 2.3% more data than the original, so that there is no great burden on the calculation amount and the final data storage amount. Similarly, the method can also be used for effectively solving the problem that the LCD display panel has uneven brightness in the horizontal direction.
In some embodiments, the obtained rectangular areas of the LCD display panel may be 8 × 8 pixels or 4 × 4 pixels, and the boundary points of the substrates COF2 to COF12 are obtained at intervals of 8 or 4 pixels on the boundary line, so that a user can adjust the precision of the sampling points required by the luminance obtaining device according to the size of the LCD display panel and the number of the substrates.
In some embodiments, the brightness values of the right-angled points (e.g. 8, 16, 24, etc. in fig. 3, and fig. 5: N2, N4) not on the boundary lines of the COFs 1 to COF12 of the plurality of substrates can be deleted. Therefore, the compensation values are calculated only for the brightness values of a plurality of right-angle points (such as reference numerals 1, 320 and 640 in fig. 2) and a plurality of demarcation points (such as reference numerals P1 and P2 in fig. 5) on the boundary lines of the plurality of substrates COF1 to COF 12. Thereby further reducing the amount of computation and ultimately the amount of data storage.
While the invention has been described with reference to specific embodiments, the scope of the invention is not limited thereto, and those skilled in the art can easily conceive various equivalent modifications or substitutions within the technical scope of the invention. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
