Description

Technical Field

[0001] The present application relates to the field of image display technology, and in particular to an image display method, display panel, device, and storage medium. Background Art

[0002] During the display panel driving process, the higher the display panel's driving bit depth (bit-depth), the more detailed the displayed image, the smoother the color transition, and the better the image quality. However, the finer the control, the more circuitry is required, which increases the driving cost. To save driving costs and maintain image quality, dithering technology is currently mainly used, such as displaying 8-bit data through 6-bit dithering. However, in the new 6-bit frame rate control (FRC) data transmission, because the dither pattern is divided into two domains, time and space, it is easy for the carry points between frames to overlap, resulting in noise.

[0055] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0056] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0057] To facilitate understanding of this application, we first briefly explain frame rate control (FRC) technology. FRC dithering is divided into temporal dithering and spatial dithering. Taking 6-bit display as an example, temporal dithering accumulates time so that the first frame is displayed as 6-bit grayscale A, the second frame as 6-bit grayscale A+1, the third frame as 6-bit grayscale A, and the fourth frame as 6-bit grayscale A+1. This visually creates a grayscale B that is brighter than A and darker than A+1. The driver only needs to process data from A and A+1 to produce the redundant grayscale B. This creates an effect similar to 8-bit, and with fewer data processing modules, driver costs can be reduced. Spatial dithering, on the other hand, combines both A and A+1 within the same frame, while also dithering out the B grayscale effect. Its meaning is the same as temporal dithering. In actual use, the arrangement of grayscale A sub-pixels and grayscale A+1 sub-pixels in the spatial and temporal domains is very important, and improper arrangement will easily lead to abnormalities.

[0058] The schematic diagram of the comparison of the overlapping effect of two frames of images is as follows Figure 1 In the first frame A, the position of 1 is a carry, indicating that there are 5 carries. The second frame A also has 5 carries, completely overlapping with the first frame A. Although the rows and columns within the frame are balanced, and the frame balance is very good, the overlap of these two frames, such as the overlapping figure A, indicates that the position of 2 in the overlapping figure A indicates that the carry is repeated twice, and the position of 0 indicates that it is not carried out at all. This will cause uneven overlap and the displayed effect may be noisy. For example, from the actual display effect, the bright areas will be always bright, and the dark areas will be always dark, resulting in uneven brightness. However, this problem does not occur in the overlapping figure B formed by the first frame B and the second frame B. Compared with the overlapping figure A, the overlapping figure B is much more balanced.

[0059] In order to solve the technical problem of noise caused by overlapping carry points of adjacent frames in the prior art, the present application provides an image display method, display panel, device and storage medium, which can screen the arrangement order of four golden samples determined based on the carry situation of the jitter golden frame, and select a target arrangement order with carry balance from them. Therefore, for each minimum jitter unit, the four golden samples are superimposed and displayed in sequence according to the target arrangement order to realize the display of pixel data on the display panel, avoiding the noise problem caused by overlapping carry points of adjacent frames.

[0060] Example 1

[0061] The first embodiment of the present application provides an image display method, which can be applied to a display panel, such as a liquid crystal display panel LCD, etc., without limitation. Figure 2 , the image display method comprises:

[0062] Step 201 : Obtain pixel data of an image to be displayed; the pixel data has a first bit depth, which is higher than a driving bit depth of a display panel.

[0063] To reduce driving costs, LCDs typically use a lower driver bit depth design. Conversely, to improve display quality, the pixel data in the image data input to the LCD is often designed with a higher bit depth. Therefore, the pixel data bit depth (first bit depth) in the image data is higher than the LCD's driver bit depth. For example, when the LCD's driver bit depth is 6 bits, the pixel data bit depth in the input image data may be 8, 10, or even 12 bits.

[0064] In one embodiment, obtaining pixel data of an image to be displayed includes: obtaining received image data; wherein the image data has a third bit depth, the third bit depth is higher than the driving bit depth and lower than the first bit depth; and upgrading the image data from the third bit depth to the first bit depth to obtain pixel data.

[0065] In this embodiment, in order to obtain pixel data of the image to be displayed, the received image data must first be obtained. The bit depth of the image data may be 8 bits, for example, and the timing controller TCON may be used to increase the bit depth to obtain pixel data with the first bit depth (for example, 10 bits).

[0066] Step 202 : determining a minimum dithering unit according to the difference between the first bit depth and the driving bit depth, and determining a dithering golden frame for each minimum dithering unit according to the pixel data; wherein the dithering golden frame has the same number of carries in the row direction and the column direction.

[0067] In one embodiment, a minimum jitter unit is determined based on a difference between a first bit depth and a driving bit depth, and a jitter golden frame of each minimum jitter unit is determined based on pixel data, including: obtaining a difference between a first bit depth and a driving bit depth; determining the number of rows and columns of the minimum jitter unit based on the difference raised to a power of two, wherein the number of rows is equal to the number of columns; determining pre-jitter pixel data and post-jitter pixel data of the minimum jitter unit based on the pixel data; and determining a jitter golden frame based on the post-jitter pixel data and the pre-jitter pixel data.

[0068] This embodiment uses a specific example to illustrate this. For example, if the TCON outputs 10-bit data and the display panel's driver bit depth is 6 bits, 4-bit FRC is required. Since 2 raised to the fourth power is 16, the number of rows and columns in the minimum dithering unit is 4, meaning the minimum dithering unit is a 4×4 grid. There are 16 carry-over options, from 1 to 16. The pre-dithering and post-dithering pixel data of the minimum dithering unit can be determined based on the pixel data, and the dithering golden frame can be determined based on the post-dithering and pre-dithering pixel data. Figure 3 It is a schematic diagram of an 8×8 grid position, which can be divided into four 4×4 squares, and the four squares are XYZQ in sequence. Figure 4 This is a schematic diagram of different frames in an 8×8 grid. The overlaps between the first and second frames (X1 / 2, Y1 / 2, Q1 / 2, Z1 / 2), between the second and third frames (X2 / 3, Y2 / 3, Q2 / 3, Z2 / 3), between the third and fourth frames (X3 / 4, Y3 / 4, Q3 / 4, Z3 / 4), and between the fourth frame and the first frame (X4 / 1, Y4 / 1, Q4 / 1, Z4 / 1) must all be equalized.

[0069] Step 203 : determining four golden samples according to the carry condition of the dithered golden frame; wherein the four golden samples are superimposed to form the dithered golden frame, and the rows and columns within the golden samples are evenly distributed.

[0070] In one embodiment, determining four golden samples based on the carry status of the dithered golden frame includes: determining multiple golden sample groups based on the number of carries in the dithered golden frame in the row direction or the column direction; wherein each golden sample group includes four target samples; and determining a target golden sample group from the multiple golden sample groups, and using the four target samples in the target golden sample group as the four golden samples.

[0071] In this embodiment, the carry 5 is used as an example for explanation. Figure 5Figure 1 shows a 4×4 grid overlap equalization diagram. Each gold sample (Gold1, Gold2, Gold3, and Gold4) is evenly distributed within rows and columns, with balanced polarity within the frame. The gold frame derived by superimposing the four gold samples is carry-balanced. It should be noted that since the number of carries is 5, it is not completely evenly distributed across four rows or columns. Therefore, even rows and columns can be considered evenly distributed if three rows have one carry, one row has two carries, three columns have one carry, and one column has two carries. Based on the determined gold frame, multiple gold sample groups with internal carry balance can be obtained. A target gold sample group can be determined from these multiple gold sample groups, and the four target samples in this target gold sample group are used as the four gold samples. For example, in this embodiment, Gold1, Gold2, Gold3, and Gold4 are selected as the four gold samples.

[0072] Step 204 : determining a target order of arrangement of the four golden samples with balanced carry according to the carry arrangement of the four golden samples.

[0073] In one embodiment, a target permutation sequence of the four gold samples with balanced carry is determined based on the carry permutation of the four gold samples, including: calculating a superimposed graph after any two gold samples are superimposed; determining a target superimposed graph with uneven carry permutation in the superimposed graph; determining two target gold samples corresponding to the target superimposed graph; sorting the four gold samples according to a rule that the two target gold samples are non-adjacent to obtain multiple permutation sequences with balanced carry; and selecting one of the multiple permutation sequences as the target permutation sequence.

[0074] In this embodiment, Gold1, Gold2, Gold3 and Gold4 in the above embodiment are used to sequentially calculate the superposition graph after any two gold samples are superimposed. Figure 6 Schematic diagram of the superposition of adjacent frames. Gold1+2 represents the image formed by superimposing Gold1 and Gold2 as adjacent frames, Gold1+3 represents the image formed by superimposing Gold1 and Gold3 as adjacent frames, Gold1+4 represents the image formed by superimposing Gold1 and Gold4 as adjacent frames, Gold2+3 represents the image formed by superimposing Gold2 and Gold3 as adjacent frames, Gold2+4 represents the image formed by superimposing Gold2 and Gold4 as adjacent frames, and Gold3+4 represents the image formed by superimposing Gold3 and Gold4 as adjacent frames. It can be seen that the carry arrangement of Gold3+4 is uneven. Gold3 and Gold4 must be separated in each 4×4 square of XYZQ. Taking the 4×4 square at position X as an example, there are 4×2=8 possible arrangement orders for the four frames at position X.

[0075] Take one of the examples as follows: the X position of four frames is Gold1→Gold4→Gold2→Gold3 in sequence. In this case, the X position has 6 situations in total, such as:

[0076] The Y position of the four frames is Gold2→Gold3→Gold1→Gold4;

[0077] The four frames of Q position are Gold3→Gold2→Gold4→Gold1;

[0078] The Z position of the four frames is Gold4→Gold1→Gold3→Gold2.

[0079] In this way, the schematic diagram of uniform superposition of adjacent frames is obtained as follows Figure 7 , where in the "Polarity Distribution" column, 1, 2, 3, and 4 represent the polarity distribution of the first, second, third, and fourth frames, respectively. In the "Frame Overlay" column, 1+2 represents the overlay of the first and second frames, 1+2+3 represents the overlay of the first, second, and third frames, and 1+2+3+4 represents the overlay of four frames. In the "Adjacent Two Frames Overlay" column, 4+1 represents the overlay of the fourth frame and the first frame, 1+2 represents the overlay of the first and second frames, 2+3 represents the overlay of the second and third frames, and 3+4 represents the overlay of the third frame. Superimposed with the fourth frame, it can be seen that the superposition of adjacent frames is very uniform, that is, the carry 2 / 1 / 0 in each 4×4 square of each adjacent frame is the same. For example, the carry 2 / 1 / 0 in each 4×4 square in 4+1, 1+2, 2+3, and 3+4 are exactly the same. In addition, the superposition of 1+2+3 and 1+2+3+4 also increases successively to make the carry in each position (XYZQ) the same. Because the polarity of each 4×4 square is balanced, the overall balance is also achieved.

[0080] Here is a counterexample. If the order of the four golden samples is not restricted, that is, if the situation where the adjacent frames of Gold3 and Gold4 cannot overlap is not screened in advance, for example, the situation where Gold3 and Gold4 are adjacent is as follows:

[0081] The X position of the four frames is Gold1→Gold4→Gold3→Gold2;

[0082] The Y position of the four frames is Gold2→Gold3→Gold4→Gold1;

[0083] The four frames of Q position are Gold3→Gold2→Gold1→Gold4;

[0084] The Z position of the four frames is Gold4→Gold1→Gold2→Gold3.

[0085] Since Gold3 and Gold4 are adjacent at each position, such as Figure 8 , adjacent frames will be unevenly superimposed. For example, in the "Adjacent Frame Superposition" column, the 2 / 1 / 0 carry is very unbalanced in the 4+1 frame superposition and the 2+3 frame superposition. Although the overall balance is relatively good, there will still be slight noise. Compared with pre-screening Gold3 and Gold4 adjacent frames to prevent overlap, the effect is poor.

[0086] In this embodiment, the arrangement order of adjacent frames is obtained based on the overlapping relationship between the screening Golds, which can avoid the micro-noise phenomenon caused by the overlapping problem of adjacent frames.

[0087] Step 205 : For each minimum jitter unit, four golden samples are sequentially superimposed and displayed according to the target arrangement order, so as to display pixel data on the display panel.

[0088] The method can determine the jitter golden frame of each minimum jitter unit according to the pixel data of the image to be displayed, and screen the arrangement order of four golden samples determined based on the carry situation of the jitter golden frame, and select a target arrangement order with carry balance. Therefore, for each minimum jitter unit, the four golden samples are superimposed and displayed in sequence according to the target arrangement order, so as to realize the display of pixel data on the display panel and avoid the noise problem caused by the overlap of carry points of adjacent frames.

[0089] In one embodiment, four golden samples are superimposed and displayed in sequence according to a target arrangement order to display pixel data on a display panel, including: displaying the current display image data of the minimum jitter unit in the minimum jitter unit; reading the four golden samples in sequence according to the target arrangement order, and when a carry of the golden sample is read, retrieving a lookup logarithm table corresponding to the carry, and updating the current display image data according to the pixel data in the lookup logarithm table.

[0090] In this embodiment, when the display panel displays pixel data, four golden samples can be read in sequence according to the target arrangement order. When a carry is read from the golden sample, the lookup table (LUT) corresponding to the carry is retrieved, and the currently displayed image data is updated according to the pixel data in the LUT, so that each reading process is kept as balanced as possible to avoid noise.

[0091] Example 2

[0092] Based on the same technical concept, the second embodiment of the present application provides an image display device, such as Figure 9 , the device comprises:

[0093] An acquisition module 901 is configured to acquire pixel data of an image to be displayed; the pixel data has a first bit depth, and the first bit depth is higher than a driving bit depth of a display panel;

[0094] a first determining module 902, configured to determine a minimum jitter unit according to a difference between the first bit depth and the driving bit depth, and determine a jitter golden frame for each minimum jitter unit according to the pixel data;

[0095] A second determining module 903 is configured to determine four golden samples according to the carry condition of the jittered golden frame;

[0096] A third determining module 904 is configured to determine a target order of arrangement of the four golden samples for rounding balance according to the rounding arrangement of the four golden samples;

[0097] The display module 905 is configured to overlay and display the four golden samples in sequence according to the target arrangement order for each minimum jitter unit, so as to display the pixel data on the display panel.

[0098] The device can determine the jitter golden frame of each minimum jitter unit based on the pixel data of the image to be displayed, and screen the arrangement order of four golden samples determined based on the carry situation of the jitter golden frame, and select a target arrangement order with carry balance. Therefore, for each minimum jitter unit, the four golden samples are superimposed and displayed in sequence according to the target arrangement order, so as to realize the display of pixel data on the display panel and avoid the noise problem caused by the overlap of carry points of adjacent frames.
