Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present disclosure.
In the description of the present application, it should be noted that the terms "upper", "lower", "left", "right", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present application and simplifying the description, but do not indicate or imply that the referred devices or elements must have a specific orientation, be configured in a specific orientation, and operate, and thus, should not be construed as limiting the present application. Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Currently, display panels on the market are usually made with Standard resolution to accommodate image data based on the Video Electronics Standards Association (VESA) Standard. Wherein the standard resolution of the main stream comprises: standard Definition (SD) of 720 × 480, High Definition (HD) of 1280 × 720, Full High Definition (FHD) of 1920 × 1080, Quad High Definition (QHD) of 2560 × 1440, Ultra High Definition (UHD) of 3840 × 2160, Ultra High Definition (UHD) of 5K2K of 5120 × 2160, Ultra High Definition (UHD) of 7680 × 4320, and the like. It should be noted that the display panel with a resolution of 5120 × 2160 refers to a display panel with a resolution of 5120 in the horizontal direction and a resolution of 2160 in the vertical direction, that is, each row includes 5120 pixel units, and each column includes 2160 pixel units. In this application, a row refers to a horizontal row extending in the horizontal direction, and a column refers to a vertical column extending in the vertical direction.
When a large-sized liquid crystal panel is manufactured, since it is difficult to perform the entire exposure, the large-sized display panel is usually exposed by stitching the existing small-panel photo mask. However, large-sized display panels produced by tiling of reticles may have a particular resolution (non-standard resolution). For example, a conventional 86-inch display panel made of an 86-inch photomask comprises 16S-COFs, wherein each S-COF is used for driving 240 rows of pixel units, and each row of pixel units comprises 2160 pixel units, so that the 16S-COFs can drive the 86-inch display panel with the resolution of 3840 × 2160 to display. When the existing 86-inch mask and the newly opened 50-inch mask are spliced and exposed to form a 107-inch display panel, the 107-inch display panel includes 21S-COFs (wherein, the portion of the display panel corresponding to the 86-inch mask includes 16S-COFs, and the portion of the display panel corresponding to the 50-inch mask includes 5S-COFs), so that the 21S-COFs can drive the 107-inch display panel with the resolution of 5040 × 2160 to display. The resolution of 5040 × 2160 does not belong to the standard resolution described above, but to a special resolution. The conventional TCON can be applied to the architectures of 12S-COFs, 16S-COFs, 20S-COFs or 24S-COFs, and cannot drive a display panel with special resolution comprising 21S-COFs.
In order to solve the technical problem that the conventional TCON cannot drive a display panel with a special resolution, the present application provides a driving circuit 100 for a display panel.
As shown in fig. 1, the driving circuit 100 is used for driving a display panel 200. The driving circuit 100 includes a System On Chip (SOC) 101 and a Timing Control board (TCON) 102, which are connected to each other. The display panel 200 includes N source drivers 210, each of the source drivers 210 is connected to the timing control board 102, and each of the source drivers 210 is configured to drive a columns of pixel units P arranged in the horizontal direction in the display panel 200, where N and a are positive integers. Illustratively, the source driver 210 includes a source driver chip, and the source driver chip may be mounted on a source Flexible Circuit board (FPC) by a COF (chip on film) method to form an S-COF.
Specifically, the pixel units P in the same column are connected to the same source driver 210 through the same set of data lines 201. In the embodiment of the present application, each of the pixel units P includes: red (R), green (G), and blue (B)3 sub-pixels (not shown), each group of the data lines 201 includes 3 sub-data lines (not shown), and the sub-pixels in the same column are connected to the same source driver 210 through the same sub-data line. The present embodiment describes the driving circuit 100 provided in the present application, taking N-21, a-240, that is, X2-N × a-5040 as the actual resolution of the display panel 200 in the horizontal direction, and 2160 as the actual resolution in the vertical direction as an example. Each of the source drivers 210 is used for driving 240 columns of pixel units P in the display panel 200, which means: each of the source drivers 210 includes 720 data channels, and the 720 data channels are connected to the 720 sub-data lines in a one-to-one correspondence manner, so as to drive 720 columns of sub-pixels, thereby implementing the driving of 240 columns of pixel units P.
In the embodiment of the present application, the driving circuit 100 is configured to output M groups or O groups of image data to drive the display panel 200, where M and O are positive integers, and O is a positive integer<N<And M. It should be noted that, in this embodiment, the driving circuit 100 can output the number m of sets of image datajThe number of sets m of image data that the driver circuit 100 can output is determined by the compatibility of the existing standard driver circuitjForm a set U, where U ═ m1,m2,……mJ}，m1<m2<……<mJAnd J is an integer greater than 1. M and O are both values in the set U and are closest to N. Illustratively, the set U includes 12, 16, 20, 24, and so on. In this embodiment, the driving circuit 100 provided in this application is described by taking M-24 and O-20 as examples.
In the embodiment of the present application, the driving circuit 100 is further configured to receive source image data with a resolution of X0 × Y, and perform data insertion on the source image data to obtain to-be-processed image data with a resolution of X1 × Y. Where X0 is the standard resolution in the horizontal direction, Y is the standard resolution in the vertical direction, and X1 is mxa, X1> X0. Specifically, the system on chip 101 is configured to receive the source image data. Illustratively, in an embodiment, the system on chip 101 is further configured to perform data insertion on the source image data, obtain the to-be-processed image data with the resolution of X1 × Y, and transmit the to-be-processed image data with the resolution of X1 × Y to the timing control board 102. In another embodiment, the system on chip 101 is configured to transmit the received source image data to the timing control board 102, and the timing control board 102 performs data insertion on the source image data to obtain the to-be-processed image data with the resolution of X1 × Y. Illustratively, the present embodiment takes X1 ═ 24 × 240 ═ 5760 as an example, and describes the driving circuit 100 provided in the present application.
In this embodiment, the driving circuit 100 is further configured to process the image data to be processed to obtain M groups of image data, and output the first N groups of image data in the M groups of image data to the corresponding source drivers 210, respectively, so as to drive the display panel 200. Specifically, the timing control board 102 is configured to process the image data to be processed. In the embodiment of the present application, in the M groups of image data, the first N groups of image data correspond to the source image data; the remaining (M-N) sets of image data are invalid data, and as shown in fig. 1, the remaining (M-N) sets of image data are output to (M-N) dummy source drivers 210 '(corresponding to the gray and shaded areas that are virtualized in the figure), wherein the dummy source drivers 210' are virtualized and not actually present on the display panel 200, in other words, the remaining (M-N) sets of image data are not output to the display panel 200.
Further, in the embodiment of the present application, the driving circuit 100 is specifically configured to insert invalid data with a resolution of B × Y after the source image data, so as to obtain the to-be-processed image data with the resolution of X1 × Y, where B ═ X1-X0. In this embodiment, B5760-. Illustratively, the invalid data may be data that causes the pixel unit to display as a black image.
Further, in this embodiment of the application, the driving circuit 100 is further specifically configured to, when it is determined that X0 is greater than an actual resolution X2 of the display panel in a horizontal direction, remove pixels from the source image data according to a pixel removal rule to obtain image data matching the resolution of the display panel, and insert invalid data with a resolution of B × Y after the source image data processed by removing pixels, so as to obtain to-be-processed image data with the resolution of X1 × Y, where X2 is N × a. Exemplarily, in the present embodiment, X2 ═ 5040.
Further, in an embodiment, the driving circuit 100 is further specifically configured to calculate a difference Δ X between X0 and X2, remove image data with a column number greater than X2 in the source image data, and fill invalid data with a resolution Δ X × Y after the remaining image data, so as to obtain image data matching the resolution of the display panel. Thus, the pixel removing rule is simple and easy to realize. In the present application, the removal of a certain column of image data means that the column of image data is deleted, and the image data following the column of image data is sequentially moved forward by one column. Exemplarily, in the present embodiment, Δ X is 5120 and 5040 is 80.
In another embodiment, the driving circuit is further configured to calculate a difference Δ X between X0 and X2, and remove image data with a resolution of Δ X × Y from the source image data at equal intervals, and fill in invalid data with a resolution of Δ X × Y after the remaining image data, so as to obtain image data matching the resolution of the display panel, where C and D are positive integers and Δ X ═ C × D. Therefore, the eyes of the user cannot easily distinguish the missing of the image, and the display effect is better. Exemplarily, in the present embodiment, Δ X is 5120 and 5040 is 80.
As described above, the conventional standard driving circuit 100 can output 20 or 24 sets of image data, but cannot output 21 sets of image data, and thus cannot drive the display panel 200 having 21 source drivers. In this embodiment, the display panel 200 can be driven by performing data insertion on the source image data to obtain to-be-processed image data with a resolution of 5760 × 2160, processing the to-be-processed image data to obtain 24 groups of image data, and respectively outputting the first 21 groups of image data in the 24 groups of image data to the corresponding source drivers 210. Since the resolution of the source image data is 5120 × 2160 and the actual resolution of the display panel 200 is 5040 × 2160, the image displayed by the display panel 200 may lack a partial image with a resolution of 80 × 2160, such as a gray area shown in fig. 1, compared to the original image corresponding to the source image data.
In another embodiment, the display panel 200 may also be driven by cropping the original image data to obtain image data to be processed with a resolution of 4800 × 2160, processing the image data to be processed to obtain 20 groups of image data, and outputting the 20 groups of image data to the first 20 source drivers of the 21 source drivers in a one-to-one correspondence manner. However, since the resolution of the source image data is 5120 × 2160, the resolution actually used by the display panel 200 is only 4800 × 2160, and thus, the image displayed by the display panel 200 may lack the partial image with the resolution of 320 × 2160 compared to the original image corresponding to the source image data. Obviously, compared with the driving method of outputting 20 groups of image data, the driving method of outputting 24 groups of image data displays fewer missing images, the utilization rate of the display panel 200 is higher, and the display effect is better.
The driving circuit 100 provided by the present application receives source image data with a resolution of X × Y; performing data insertion on the source image data to obtain to-be-processed image data with the resolution of X1 multiplied by Y; and processing the image data to be processed to obtain M groups of image data, and outputting the first N groups of image data in the M groups of image data to the corresponding source drivers 210, respectively, so as to drive the display panel 200. According to the display panel driving method and device, the existing standard driving circuit 100 is used for carrying out data insertion and data processing on the source image data, the display panel 200 with the special resolution ratio can be driven to display, the hardware structure of the standard driving circuit is not required to be redesigned, the production cost can be reduced, the development period can be shortened, and the display panel 200 with the special resolution ratio can be popularized and applied.
Based on the same inventive concept, the present application further provides a driving method of a display panel, the driving method is used for driving the display panel 200, the display panel 200 includes N source drivers 210, each source driver 210 is used for driving a columns of pixel units arranged in the horizontal direction in the display panel 200, where N and a are positive integers.
Illustratively, the present embodiment describes the driving method proposed by the present application with N-21, a-240, that is, X2-N × a-5040 in the horizontal direction and 2160 in the vertical direction of the display panel 200 as an example. Of course, in other embodiments, N and a may be other positive integers, for example, N is 22, that is, the actual resolution of the display panel 200 in the horizontal direction is X2 is 22 × 240 is 5280, which is not limited herein.
As shown in fig. 2, the method specifically includes the following steps:
It should be noted that, in this embodiment, the driving circuit 100 can output the number m of sets of image datajThe number of sets m of image data that the driver circuit 100 can output is determined by the compatibility of the existing standard driver circuitjForm set U (U ═ m)1,m2,……mJ}) in which m1<m2<……<mJAnd J is an integer greater than 1. Illustratively, the set U includes 12, 16, 20, 24, and so on.
The Standard resolution is a resolution based on the Video Electronics Standards Association (VESA) Standard.
In the embodiment of the present application, in the M groups of image data, the first N groups of image data correspond to the source image data; the remaining (M-N) sets of image data are invalid data, and the remaining (M-N) sets of image data are output to the (M-N) dummy source drivers 210' in a one-to-one correspondence. The dummy source driver 210' is virtualized and is not actually present on the display panel 200, in other words, the remaining (M-N) sets of image data are not output to the display panel 200.
It is understood that the driving method provided by the present application can also be used for driving a motor including mjIn the display panel 200 of the source drivers 210 (i.e. the display panel with the standard resolution), at this time, the number of groups of the image data output by the driving circuit 100 matches the number of the source drivers 210, and the driving circuit 100 does not need to insert data into the source image data, and directly processes the source image data to obtain N groups of image data and outputs the N groups of image data to the N source drivers 210 in a one-to-one correspondence manner, so as to drive the display panel 200.
Further, the step 64 specifically includes:
and determining M through the driving circuit, and inserting invalid data with the resolution of B multiplied by Y after the source image data so as to obtain the image data to be processed with the resolution of X1 multiplied by Y, wherein B is X1-X0. In this embodiment, B5760-. Illustratively, the invalid data may be data that causes the pixel unit to display as a black image.
Further, as shown in fig. 3, the step 64 specifically includes the following steps:
in step 641, M is determined by the driving circuit 100.
In step 642, it is determined whether X0 is greater than the actual resolution X2 of the display panel in the horizontal direction. Wherein X2 is nxa. If X0> X2, perform step 643. Otherwise, step 644 is performed. Exemplarily, in the present embodiment, X0 is 5120, and X2 is 5040, so X0> X2.
In step 643, pixels of the source image data are removed according to a pixel removal rule by the driving circuit 100, so as to obtain image data matching with the resolution of the display panel 200. After this step is performed, step 644 is performed.
It should be noted that, in this embodiment, since X0> X2, that is, the resolution of the source image data in the horizontal direction is greater than the resolution of the display panel in the horizontal direction, the source image data needs to be subjected to resolution reduction processing (i.e., pixel removal processing), and partial image data is removed before the source image data can be adapted to the display panel.
It is understood that the pixel removal rule can be selected according to actual requirements, and the present application exemplarily provides two pixel removal rules, which are as follows.
As shown in fig. 4, in one embodiment, the pixel removal rule includes the following steps:
In step 6432, the image data with column number greater than X2 (e.g. 5040) in the source image data is removed, and invalid data with resolution Δ X × Y is filled in after the remaining image data. After this step is performed, step 644 is performed. Thus, the pixel removing rule is simple and easy to realize.
In the present application, the removal of a certain column of image data means that the column of image data is deleted, and the image data following the column of image data is sequentially moved forward by one column. It is obvious that, in the image displayed on the display panel 200 by the image data subjected to the pixel removal processing according to the pixel removal rule in the present embodiment, a partial image having a resolution Δ X × Y (for example, 80 × 2160) is missing on one side (for example, the right side in the horizontal direction) of the original image compared to the original image corresponding to the original image data.
In other embodiments, partial image data may be removed from both sides of the source image data, for example, image data having a column number less than or equal to Δ X/2 (e.g., 40) and greater than (X0- Δ X/2), for example, 5080, in the source image data, so that partial images having a resolution of (Δ X/2) × Y (e.g., 40 × 2160) are missing from both left and right sides of the original image compared to the original image corresponding to the source image data.
As shown in fig. 5, in one embodiment, the pixel removal rule includes the following steps:
Specifically, the removal pixel interval may be determined according to the resolution of the display panel in the horizontal direction, taking C ═ Δ X ═ 80 and D ═ 1 as an example, and the removal pixel interval [5040/80] ═ 63, that is, 1 column of image data is removed from the 1 st column of image data, every 63 columns of image data, exemplarily, (63 × n + a) th column of image data is removed, where a and n are integers, and 0 ≦ n ≦ 80, 1 ≦ a ≦ 63, preferably, a ≦ 1, where [ ] denotes a rounding symbol, that is, an integer part of the calculation result. It can be understood that 1 column of image data is removed from every 63 columns of image data, so that the user's eyes cannot easily distinguish the missing image, and the display effect is better. In other embodiments, a, C, and D are other values satisfying the above conditions, and for example, C is 40 and D is 2, which are not listed here.
