Detailed implementation manners

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0020] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0021] For ease of understanding this application, first, a brief introduction to the frame rate control (FRC) technology is provided. FRC jitter is divided into temporal dithering and spatial dithering. Taking the example of displaying 8 bits with 6 bits, temporal dithering means that in terms of time accumulation, the first frame is displayed as gray level A of 6 bits, the second frame is displayed as gray level A + 1 of 6 bits, the third frame is displayed as gray level A of 6 bits, and the fourth frame is displayed as gray level A + 1 of 6 bits. Thus, visually, a gray level B that is brighter than A and darker than A + 1 is displayed. And the driver only needs to process the data of A and A + 1 to obtain the extra gray level B. Because the effect is close to 8 bits and the data processing module is less, the cost of the driver can be reduced. Among them, spatial dithering means that within the same frame, there is both A and A + 1, and then the effect of gray level B can also be dithered out, and its meaning is the same as that of temporal dithering. In actual use, the arrangement of gray level A sub-pixels and gray level A + 1 sub-pixels in the spatial and temporal domains is very particular. Improper arrangement is likely to cause abnormalities.

[0022] The schematic diagram of the overlapping effect of two frames of images is as Figure 1 , the position of 1 in the first frame A is a carry. It can be seen that there are 5 carries here, and there are also 5 carries in the second frame A, which completely overlaps with the first frame A. Although the row and column balance within the frame and the frame balance are done well, the overlap formed by these two frames, such as the overlapping graphic A, the position of 2 in the overlapping graphic A indicates that the carry is repeated 2 times, and the position of 0 indicates that there is no carry at all. This situation will cause the problem of overlapping imbalance, and the displayed effect may show noise. For example, from the actual display effect, the bright places are always bright and the dark places are always dark, resulting in uneven brightness and darkness. And for the overlapping graphic B formed by the first frame B and the second frame B, there will be no such situation. Compared with the overlapping graphic A, the overlapping graphic B is much more balanced.

[0023] To solve the technical problem of noise caused by the overlap of adjacent frame carry points in the prior art, this application provides an image display method, a display panel, a device, and a storage medium, which can screen according to the arrangement order of four golden samples determined by the carry situation of the dither golden frame, and select the target arrangement order with balanced carry from them. Thus, for each minimum dither 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 adjacent frame carry points.

[0024] Embodiment 1 The first embodiment of this 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. As Figure 2, the image display method includes: Step 201, obtaining pixel data of an image to be displayed; the pixel data has a first bit depth, and the first bit depth is higher than the driving bit depth of the display panel.

[0025] To reduce the driving cost, liquid crystal displays usually adopt a design scheme with a lower driving bit depth. In contrast, to improve the display effect, in the image data input to the liquid crystal display, the bit depth of the pixel data is often higher. Therefore, the bit depth (the first bit depth) of the pixel data in the image data is higher than the driving bit depth of the liquid crystal display. For example, when the driving bit depth of the liquid crystal display is 6 bit, the bit depth of the pixel data in the input image data may be 8 bit, 10 bit, or even 12 bit.

[0026] 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 upscaling the image data from the third bit depth to the first bit depth to obtain pixel data.

[0027] In this embodiment, to obtain the pixel data of the image to be displayed, first, the received image data needs to be obtained. The bit depth of this image data can be, for example, 8 bit, and it can be upscaled by the timing controller TCON to obtain pixel data with the first bit depth (for example, 10 bit).

[0028] 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 carry numbers of the dithering golden frame in the row direction and the column direction are the same.

[0029] In one embodiment, 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 includes: obtaining the difference between the first bit depth and the driving bit depth; determining the number of rows and the number of columns of the minimum dithering unit according to the power of two of the difference; wherein, the number of rows is equal to the number of columns; determining the pre-dithering pixel data and the post-dithering pixel data of the minimum dithering unit according to the pixel data; and determining the dithering golden frame according to the post-dithering pixel data and the pre-dithering pixel data.

[0030] In this embodiment, a specific example is used for illustration. For example, if the data output by the TCON is 10-bit depth data and the driving depth of the display panel is 6-bit, then 4-bit FRC is required at this time. The fourth power of 2 is 16, so the number of rows and columns of the minimum dithering unit are both 4, that is, the minimum dithering unit is a 4×4 grid, and there are 16 cases of carry from 1 to 16. The pre-dithering pixel data and post-dithering pixel data of the minimum dithering unit can be determined according to the pixel data, and the dithering gold frame can be determined according to the post-dithering pixel data and the pre-dithering pixel data. Figure 3 It is a schematic diagram of the positions of an 8×8 grid, which can be divided into four 4×4 grids, and the four grids are XYZQ in sequence. Figure 4 It is a schematic diagram of different frames of an 8×8 grid. The overlaps between the first frame and the second frame (X1 / 2, Y1 / 2, Q1 / 2, Z1 / 2), between the second frame and the third frame (X2 / 3, Y2 / 3, Q2 / 3, Z2 / 3), between the third frame and the fourth frame (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) all need to be balanced.

[0031] Step 203: Determine four gold samples according to the carry situation of the dithering gold frame; among them, the four gold samples are superimposed to form the dithering gold frame, and the row and column distributions inside the gold samples are uniform.

[0032] In one embodiment, determining four gold samples according to the carry situation of the dithering gold frame includes: determining multiple groups of gold samples according to the carry quantity of the dithering gold frame in the row direction or the column direction; among them, each group of gold samples includes four target samples; determining a target group of gold samples from the multiple groups of gold samples, and using the four target samples in the target group of gold samples as the four gold samples.

[0033] In this embodiment, taking the carry of 5 as an example for illustration, Figure 5It is a schematic diagram of the overlap balance of a 4×4 grid. Among them, for each gold sample (Gold1, Gold2, Gold3, Gold4), the row and column distributions inside are uniform, the polarity balance within the frame is maintained, and the carry balance of the gold frame obtained by superimposing the 4 Golds is achieved. It should be noted that since the carry number is 5, when distributed in four rows or four columns, it cannot be completely evenly distributed. Then, it is considered that the row and column distributions are uniform when there is 1 carry in three rows and 2 carries in one row, and 1 carry in three columns and 2 carries in one column. Based on the determined gold frame, multiple groups of gold samples with internal carry balance can be obtained. A target group of gold samples can be determined from multiple groups of gold samples, and the four target samples in the target group of gold samples are used as the four gold samples. For example, in this embodiment, Gold1, Gold2, Gold3, and Gold4 are selected as the four gold samples.

[0034] Step 204: Determine the target arrangement order for the carry balance of the four gold samples according to the carry arrangement of the four gold samples.

[0035] In one embodiment, determining the target arrangement order for the carry balance of the four gold samples according to the carry arrangement of the four gold samples includes: calculating the superimposed graph after superimposing any two gold samples; determining the target superimposed graph with uneven carry arrangement in the superimposed graph; determining the two target gold samples corresponding to the target superimposed graph; sorting the four gold samples according to the rule that the two target gold samples are not adjacent to obtain multiple carry balance arrangement orders; and selecting one from the multiple arrangement orders as the target arrangement order.

[0036] In this embodiment, Gold1, Gold2, Gold3, and Gold4 in the above embodiment are continued to be used, and the superimposed graph after superimposing any two gold samples is calculated in sequence. Figure 6 The superimposed schematic diagrams corresponding to adjacent frames, where Gold1+2 represents the graph obtained by superimposing Gold1 and Gold2 as adjacent frames, Gold1+3 represents the graph obtained by superimposing Gold1 and Gold3 as adjacent frames, Gold1+4 represents the graph obtained by superimposing Gold1 and Gold4 as adjacent frames, Gold2+3 represents the graph obtained by superimposing Gold2 and Gold3 as adjacent frames, Gold2+4 represents the graph obtained by superimposing Gold2 and Gold4 as adjacent frames, Gold3+4 represents the graph obtained by superimposing Gold3 and Gold4 as adjacent frames. It can be seen that the carry arrangement of Gold3+4 is uneven, and Gold3 and Gold4 need to be separated in each 4×4 grid of XYZQ. Taking the 4×4 grid at the X position as an example, there are a total of 4×2 = 8 arrangement orders for the four frames at the X position.

[0037] Taking one of them as an example, it is illustrated as follows: For the four frames at the X position, they are successively Gold1 → Gold4 → Gold2 → Gold3. In this case at the X position, there are 6 situations for YQZ. For example: For the four frames at the Y position, they are successively Gold2 → Gold3 → Gold1 → Gold4; For the four frames at the Q position, they are successively Gold3 → Gold2 → Gold4 → Gold1; For the four frames at the Z position, they are successively Gold4 → Gold1 → Gold3 → Gold2.

[0038] In this way, the schematic diagram of uniform superposition of adjacent frames obtained is as Figure 7 , where in the "Polarity Distribution" column, 1, 2, 3, and 4 respectively represent the polarity distributions of the first frame, the second frame, the third frame, and the fourth frame. In the "Frame Superposition" column, 1 + 2 represents the superposition of the first frame and the second frame, 1 + 2 + 3 represents the superposition of the first frame, the second frame, and the third frame, 1 + 2 + 3 + 4 represents the superposition of the four frames. In the "Adjacent Two - Frame Superposition" column, 4 + 1 represents the superposition of the fourth frame and the first frame, 1 + 2 represents the superposition of the first frame and the second frame, 2 + 3 represents the superposition of the second frame and the third frame, 3 + 4 represents the superposition of the third frame and 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 grid of the superposition of each adjacent frame is respectively the same. For example, the carry 2 / 1 / 0 in each 4×4 grid of 4 + 1, 1 + 2, 2 + 3, 3 + 4 is respectively exactly the same. In addition, the superposition of 1 + 2 + 3 and the superposition of 1 + 2 + 3 + 4 also increase successively so that the carry is the same at each position (XYZQ). Because the polarity is balanced in each 4×4 grid, the overall is also balanced.

[0039] Next, an example to the contrary is given. If there is no restriction on the arrangement order of the four gold samples, that is, the situation where the adjacent frames of Gold3 and Gold4 cannot overlap is not screened out in advance. For example, the following situation where Gold3 and Gold4 are adjacent: For the four frames at the X position, they are successively Gold1 → Gold4 → Gold3 → Gold2; For the four frames at the Y position, they are successively Gold2 → Gold3 → Gold4 → Gold1; For the four frames at the Q position, they are successively Gold3 → Gold2 → Gold1 → Gold4; For the four frames at the Z position, they are successively Gold4 → Gold1 → Gold2 → Gold3.

[0040] Since Gold3 and Gold4 are adjacent at each position, as Figure 8, the uneven superposition of adjacent frames will occur. For example, in the "superposition of two adjacent frames" column, in the superposition of 4 + 1 frames and 2 + 3 frames, the 2 / 1 / 0 carry is very unbalanced. Although the overall balance is also relatively good, there will still be slight noise, which is less effective compared to the case where adjacent frames of Gold3 and Gold4 are not allowed to overlap by early screening.

[0041] In this embodiment, according to the overlapping relationship between the screened Golds, the arrangement order of adjacent frames is obtained, which can avoid the micro-noise phenomenon caused by the overlapping of adjacent frames.

[0042] Step 205, for each minimum dithering unit, the four gold samples are sequentially superposed and displayed in accordance with the target arrangement order to display the pixel data on the display panel.

[0043] This method can determine the dithering gold frames of each minimum dithering unit according to the pixel data of the image to be displayed, and screen the arrangement order of the four gold samples determined based on the carry situation of the dithering gold frames, and select the target arrangement order with balanced carry from them. Therefore, for each minimum dithering unit, the four gold samples are sequentially superposed and displayed in accordance with the target arrangement order to realize the display of pixel data on the display panel, avoiding the noise problem caused by the overlapping of adjacent frame carry points.

[0044] In one embodiment, the four gold samples are sequentially superposed and displayed in accordance with the target arrangement order to display the pixel data on the display panel, including: displaying the current display image data of the minimum dithering unit in the minimum dithering unit; sequentially reading the four gold samples in accordance with the target arrangement order, and when the carry of the gold sample is read, calling the lookup logarithmic table corresponding to the carry, and updating the current display image data according to the pixel data in the lookup logarithmic table.

[0045] In this embodiment, during the process of displaying pixel data on the display panel, the four gold samples can be sequentially read in accordance with the target arrangement order. When the carry of the gold sample is read, the lookup logarithmic table (LUT logarithmic table, that is, look up table) corresponding to the carry is called, and the current display image data is updated according to the pixel data in the lookup logarithmic table, so that each reading process can be kept balanced as much as possible to avoid the appearance of noise.

[0046] Embodiment 2 Based on the same technical concept, the second embodiment of the present application provides an image display device, as Fig. 9 , the device includes: An acquisition module 901, 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 the driving bit depth of the display panel; The first determination module 902 is configured to determine a minimum dithering unit according to the difference between the first bit depth and the driving bit depth, and determine a dithering golden frame for each minimum dithering unit according to the pixel data; The second determination module 903 is configured to determine four golden samples according to the carry situation of the dithering golden frame; The third determination module 904 is configured to determine a target arrangement order in which the four golden samples are carry-balanced according to the carry arrangement situation of the four golden samples; The display module 905 is configured to, for each minimum dithering unit, sequentially superimpose and display the four golden samples in the target arrangement order, so as to display the pixel data on the display panel.

[0047] The device can determine the dithering golden frame of each minimum dithering unit according to the pixel data of the image to be displayed, screen the arrangement order of the four golden samples determined according to the carry situation of the dithering golden frame, and select a target arrangement order with carry balance therefrom. Thus, for each minimum dithering unit, the four golden samples are sequentially superimposed and displayed in the target arrangement order, so as to realize the display of the pixel data on the display panel, and avoid the noise problem caused by the overlap of adjacent frame carry points.
