Technical Field

[0001] The present invention relates to the field of display technologies, and particularly to a display method, device, equipment and storage medium. Background Art

[0002] Currently, in the field of display technologies, manufacturers use horizontal overdrive compensation to compensate for the brightness difference caused by insufficient charging time of the display. However, for a display with an adaptive synchronization function, since its refresh rate changes during use, and the debugging of horizontal overdrive compensation only compensates for a fixed high refresh rate product. When the refresh rate decreases and the charging time becomes longer, there will be a large brightness difference between adjacent two rows of the display screen, resulting in horizontal stripes on the display screen. Summary of the Invention

[0003] The purpose of the present invention is to provide a display method, device, equipment and storage medium, which improves the problem of horizontal stripes appearing on the display screen of the display.

[0004] To achieve the purpose of the present invention, the following technical solutions are provided:

[0005] In a first aspect, the present invention provides a display method for a display, including: obtaining a mixed-color screen of the display and determining its refresh rate, where the mixed-color screen includes a first row gray scale and a second row gray scale; determining a preset total compensation value and a preset block compensation value according to the refresh rate; determining a first compensation value based on the second row gray scale, the preset total compensation value and the preset block compensation value; adjusting a first actual brightness corresponding to the second row gray scale according to the first compensation value to reduce the difference between the brightness corresponding to the first row gray scale and the first actual brightness. It can be understood that adjusting the first actual brightness corresponding to the second row gray scale according to the first compensation value to reduce the difference between the brightness corresponding to the first row gray scale and the first actual brightness improves the problem of horizontal stripes appearing on the display screen of the display and enhances the display image quality of the display.

[0006] In an implementation, the determining the preset total compensation value and the preset block compensation value according to the refresh rate includes the following steps:

[0007] Dividing the refresh rate into a plurality of preset intervals according to the magnitude of the refresh rate;

[0008] Determining the preset total compensation value and the preset block compensation value for each of the preset intervals.

[0009] It can be understood that by dividing the refresh rate into multiple preset intervals and determining the preset total compensation value and the preset block compensation value for each preset interval, the accuracy and fineness of determining the preset total compensation value and the preset block compensation value are improved, and the phenomenon of horizontal streaks appearing in the display screen is improved.

[0010] In one implementation, the step of determining the preset total compensation value and the preset block compensation value according to the refresh rate further includes the following steps:

[0011] Determine a first preset voltage according to the preset interval;

[0012] Output the preset total compensation value and the preset block compensation value according to the first preset voltage.

[0013] It can be understood that determining the first preset voltage according to the preset interval and outputting the preset total compensation value and the preset block compensation value according to the first preset voltage improves the process of outputting the preset total compensation value and the preset block compensation value, enhances the accuracy of outputting the preset total compensation value and the preset block compensation value, and improves the phenomenon of horizontal streaks appearing in the display screen.

[0014] In one implementation, before obtaining the mixed-color screen of the display, the method further includes:

[0015] Obtain a first screen of the display, where the first screen includes a plurality of block data, and the block data includes red-green sub-pixels, red-blue sub-pixels, and green-blue sub-pixels;

[0016] Analyze the brightness of the red-green sub-pixels, the brightness of the red-blue sub-pixels, and the brightness of the green-blue sub-pixels of each block data of the first screen.

[0017] It can be understood that analyzing the brightness of the red-green sub-pixels, the brightness of the red-blue sub-pixels, and the brightness of the green-blue sub-pixels of each block data of the first screen improves the integrity and accuracy of the analysis of the first screen.

[0018] In one implementation, the step of analyzing the brightness of the red-green sub-pixels, the brightness of the red-blue sub-pixels, and the brightness of the green-blue sub-pixels of each block data of the first screen includes the following steps:

[0019] When the red-green sub-pixels are bright, the red-blue sub-pixels are bright, and the green-blue sub-pixels are bright and have the same brightness, and the proportion of the red-green sub-pixels in all the sub-pixels of the block data is greater than a first threshold, or the proportion of the red-blue sub-pixels in all the sub-pixels of the block data is greater than the first threshold, or the proportion of the green-blue sub-pixels in all the sub-pixels of the block data is greater than the first threshold, determine that the first screen is the mixed-color screen.

[0020] It can be understood that when the red-green sub-pixels are bright, the red-blue sub-pixels are bright, and the green-blue sub-pixels are bright and have the same brightness, and when the proportion of the red-green sub-pixels in all the sub-pixels of the block data is greater than the first threshold, or when the proportion of the red-blue sub-pixels in all the sub-pixels of the block data is greater than the first threshold, or when the proportion of the green-blue sub-pixels in all the sub-pixels of the block data is greater than the first threshold, it is determined that the first picture is a mixed-color picture, which improves the accuracy and comprehensiveness of judging the mixed-color picture.

[0021] In one implementation, the first threshold is 80%.

[0022] It can be understood that setting the first threshold to 80% improves the accuracy of determining that the first picture is a mixed-color picture.

[0023] In one implementation, the first compensation value is determined based on the second row gray scale, the preset total compensation value, and the preset block compensation value, and the following formula is used:

[0024] D = B+(A×C÷128 - A), where A is the second row gray scale, B is the preset total compensation value, C is the preset block compensation value, and D is the first compensation value.

[0025] It can be understood that using the above formula to determine the first compensation value improves the accuracy of determining the first compensation value.

Based on the second row of gray levels, the preset total compensation value, and the preset block compensation value, determine the first compensation value. Adjust the first actual brightness corresponding to the second row of gray levels according to the first compensation value to reduce the difference between the brightness corresponding to the first row of gray levels and the first actual brightness, thereby improving the phenomenon of horizontal streaks appearing on the screen of the display.

[0042] Please refer to Figure 2 , Figure 2 which is a schematic flowchart of a display method provided by an embodiment of this application. Taking the application of this method in the display process of a display as an example, the display device can include a server or an electronic device. The method includes the following steps S201 - S204, where

[0043] S201: Obtain the color mixing screen of the display and determine its refresh rate. The color mixing screen includes the first row of gray levels and the second row of gray levels.

[0044] In an embodiment of the present application, optionally, the refresh rate of the display may be 240Hz, 144Hz, 120Hz, etc., which is not limited in the present application.

[0045] In an embodiment of the present application, optionally, when there is no color mixing screen on the display, horizontal overdrive compensation does not need to be enabled to save the power consumption of the control main board and the timing controller.

[0046] Before obtaining the color mixing screen of the display, the method further includes:

[0047] Obtain the first screen of the display. The first screen includes multiple block data, and the block data includes red-green sub-pixels, red-blue sub-pixels, and green-blue sub-pixels;

[0048] Analyze the brightness of the red-green sub-pixels, the brightness of the red-blue sub-pixels, and the brightness of the green-blue sub-pixels of each block data of the first screen.

[0049] In an embodiment of the present application, optionally, the first screen includes first data. The control main board reads the first data of the next frame temporarily stored in the overdrive compensation in the current frame, and analyzes the brightness of the red-green sub-pixels, the brightness of the red-blue sub-pixels, and the brightness of the green-blue sub-pixels of each block data of the first data.

[0050] It can be understood that analyzing the brightness of the red-green sub-pixels, the brightness of the red-blue sub-pixels, and the brightness of the green-blue sub-pixels of each block data of the first screen improves the integrity and accuracy of the analysis of the first screen.

[0051] Analyzing the brightness of the red-green sub-pixels, the brightness of the red-blue sub-pixels, and the brightness of the green-blue sub-pixels of each block data of the first screen includes the following steps:

[0052] When the red-green sub-pixels are bright, the red-blue sub-pixels are bright, and the green-blue sub-pixels are bright and have the same brightness, and the proportion of the red-green sub-pixels in all the sub-pixels of the block data is greater than the first threshold, or the proportion of the red-blue sub-pixels in all the sub-pixels of the block data is greater than the first threshold, or the proportion of the green-blue sub-pixels in all the sub-pixels of the block data is greater than the first threshold, determine that the first screen is a color mixing screen.

[0053] It can be understood that when the red-green sub-pixels are bright, the red-blue sub-pixels are bright, and the green-blue sub-pixels are bright and have the same brightness, and when the proportion of the red-green sub-pixels in all the sub-pixels of the block data is greater than the first threshold, or when the proportion of the red-blue sub-pixels in all the sub-pixels of the block data is greater than the first threshold, or when the proportion of the green-blue sub-pixels in all the sub-pixels of the block data is greater than the first threshold, it is determined that the first screen is a mixed-color screen, which improves the accuracy and comprehensiveness of determining the mixed-color screen.

[0054] It should be noted that in the embodiment of the present application, the first threshold is 80%.

[0055] It can be understood that setting the first threshold to 80% improves the accuracy of determining that the first screen is a mixed-color screen.

[0056] Optionally, in the embodiment of the present application, the following method can also be used to determine that the first screen is a mixed-color screen:

[0057] The first screen includes pixel data, and the pixel data includes red-green sub-pixels, red-blue sub-pixels, and green-blue sub-pixels. Analyze the pixel data line by line to determine whether the pixel data is any one of the red-green sub-pixels, red-blue sub-pixels, and green-blue sub-pixels;

[0058] When the pixel data is red-green sub-pixels, count and sum the red-green sub-pixels to obtain a first value, divide the first value by the total number of pixels in the first screen to obtain a second value. When the second value is greater than or equal to the second threshold, determine that the first screen is a mixed-color screen. Or, when the pixel data is red-blue sub-pixels, count and sum the red-blue sub-pixels to obtain a first value, divide the first value by the total number of pixels to obtain a second value. When the second value is greater than or equal to the second threshold, determine that the first screen is a mixed-color screen. Or, when the pixel data is green-blue sub-pixels, count and sum the green-blue sub-pixels to obtain a first value, divide the first value by the total number of pixels to obtain a second value. When the second value is greater than or equal to the second threshold, determine that the first screen is a mixed-color screen. Optionally, the second threshold is 60%.

[0059] When determining whether pixel data is any one of red-green sub-pixels, red-blue sub-pixels, and green-blue sub-pixels, the following method is adopted: Analyze the gray level of each pixel data line by line and one by one. When the gray level of the pixel data is 110, the pixel data is red-green sub-pixels; Analyze the gray level of each pixel data line by line and one by one. When the gray level of the pixel data is 101, the pixel data is red-blue sub-pixels; Analyze the gray level of each pixel data line by line and one by one. When the gray level of the pixel data is 011, the pixel data is green-blue sub-pixels. It should be noted that when the sub-pixel output gray level > 0 in the pixel data, it is determined as 1, otherwise it is 0. In fact, when the gray level is relatively low, even if only red-green sub-pixels emit light, or red-blue sub-pixels emit light, or green-blue sub-pixels emit light, due to their own darkness, the problem of horizontal streaks cannot be seen. Therefore, for products of different sizes and different refresh rates, through the experimental simulation method, set the red-green sub-pixels, or red-blue sub-pixels, or green-blue sub-pixels to output 10, 20, 30, 40... 200 gray levels, and use an optical measuring instrument to confirm that the actual output gray level is consistent with the set gray level. On this basis, confirm at what gray level the problem of horizontal streaks will occur, and then use the gray level at this time as the critical value for determination; for example, when conducting experimental simulation, it is found that below 180 gray levels, the horizontal streaks in the mixed-color picture are no longer visible, then set 180 gray levels as the critical value for determination.

[0060] S202: Determine the preset total compensation value and the preset block compensation value according to the refresh rate.

[0061] Determining the preset total compensation value and the preset block compensation value according to the refresh rate includes the following steps:

[0062] Divide the refresh rate into multiple preset intervals according to the magnitude of the refresh rate.

[0063] In the embodiment of the present application, for example, when the refresh rate of a certain display is 144Hz, we segment it according to this refresh rate. 144Hz to 120Hz is the first segment, 120Hz to 100Hz is the second segment, 100Hz to 75Hz is the third segment, and 75Hz to 48Hz is the fourth segment.

[0064] Determine the preset total compensation value and the preset block compensation value for each preset interval.

[0065] In the embodiment of the present application, the preset total compensation value is a rough adjustment, and the entire picture is compensated in this way. The preset block compensation value is a fine adjustment, and fine adjustment is performed for different regions of the entire picture.

[0066] It should be noted that the number of blocks is set according to the display specifications of the chip of the display, and the number of rows and columns of the blocks is determined according to the display specifications. For example, the first block in the first row and the first column corresponds to the first block in the upper left corner of the entire screen.

[0067] Optionally, the chips of the displays commonly used in the industry currently have specifications such as 8*8, 8*4, and 16*16. According to this specification, the screen can be divided into 8*8 areas, 8*4 areas, 16*16 areas, etc. horizontally and vertically. The chips of the displays of different manufacturers may be different.

[0068] In the embodiment of the present application, the horizontal overdrive compensation compensates for the brightness and darkness differences caused by insufficient charging time between different rows. During the process of debugging the horizontal overdrive compensation screen, for the different gray levels between different rows, the output voltage of the next row is increased so that the gray level can reach the preset value within the same charging time.

[0069] In the embodiment of the present application, the preset total compensation value includes multiple data, and all the data of the entire screen are processed according to the preset total compensation value. The preset block compensation value refers to the actual output compensation value of this block.

[0070] Optionally, the preset total compensation value can be a table, which includes multiple data. In this table, the abscissa represents the gray level of the current row, the ordinate represents the target gray level of the next row, and the value filled in the table is the actual output gray level of the next row. For example, when the current row is 32 gray, that is, the abscissa is 32 and the ordinate is 64 gray, the value in the corresponding table is the gray level value that the next row should actually output.

[0071] In the embodiment of the present application, when the refresh rate of a certain display is 144Hz, we segment it according to this refresh rate. 144Hz to 120Hz is the first segment, 120Hz to 100Hz is the second segment, 100Hz to 75Hz is the third segment, 75Hz to 48Hz is the fourth segment. The preset total compensation value includes the first preset sub-value, the second preset sub-value, the third preset sub-value, and the fourth preset sub-value. The preset block compensation value includes the fifth preset sub-value, the sixth preset sub-value, the seventh preset sub-value, and the eighth preset sub-value. 144Hz to 120Hz corresponds to the first preset sub-value and the fifth preset sub-value, 120Hz to 100Hz corresponds to the second preset sub-value and the sixth preset sub-value, 100Hz to 75Hz corresponds to the third preset sub-value and the seventh preset sub-value, and 75Hz to 48Hz corresponds to the fourth preset sub-value and the eighth preset sub-value.

[0072] In an embodiment of the present application, the display includes a timing controller, a control main board, and a driving chip. The timing controller is electrically connected to the control main board, and the control main board is electrically connected to the driving chip. A selection circuit is provided inside the control main board. For example, when the refresh rate output by the control main board is within the first interval, the control main board controls the selection circuit to select the first channel and output a first preset voltage of 5V. After the timing controller receives the 5V voltage, it controls the output of a first preset sub-value and a fifth preset sub-value.

[0073] It can be understood that by dividing the refresh rate into multiple preset intervals and determining a preset total compensation value and a preset block compensation value for each preset interval, the accuracy and fineness of determining the preset total compensation value and the preset block compensation value are improved, and the phenomenon of horizontal streaks appearing in the display screen is improved.

[0074] Determining the preset total compensation value and the preset block compensation value according to the refresh rate further includes the following steps:

[0075] Determine a first preset voltage according to the preset interval;

[0076] Output the preset total compensation value and the preset block compensation value according to the first preset voltage.

[0077] For example, when the refresh rate of a certain display is 144Hz, we segment it according to this refresh rate. 144Hz to 120Hz is the first segment, 120Hz to 100Hz is the second segment, 100Hz to 75Hz is the third segment, 75Hz to 48Hz is the fourth segment. The first preset voltage corresponding to the first segment is 5V, the second preset voltage corresponding to the second segment is 3.3V, the third preset voltage corresponding to the third segment is 1.8V, and the fourth preset voltage corresponding to the fourth segment is 1.1V.

[0078] For example, the control main board controls the selection circuit to select the second channel and output a first preset voltage of 3.3V. After the timing controller receives the 3.3V voltage, it controls the output of a second preset sub-value and a sixth preset sub-value.

[0079] Optionally, the following method can also be used to improve the problem of horizontal streaks. In the experimental simulation stage, the preset total compensation value and the preset block compensation value are adjusted with the maximum refresh rate, and then the control main board is manually operated to output different refresh rates, so that the refresh rate gradually decreases. For example, if the original maximum refresh rate is 144Hz, then the refresh rate is reduced by 5Hz in each step. By observing the display with the human eye, observe at what refresh rate the horizontal overdrive compensation function has a reverse effect and causes horizontal streaks. At this time, set this value as the turn-off threshold. When the refresh rate output by the control main board changes and is lower than the turn-off threshold we set, the horizontal overdrive compensation function is turned off, so that the defect of horizontal overdrive compensation can be avoided.

[0080] It can be understood that the first preset voltage is determined according to a preset interval, and based on the first preset voltage, a preset total compensation value and a preset block compensation value are output, which improves the process of outputting the preset total compensation value and the preset block compensation value, enhances the accuracy of outputting the preset total compensation value and the preset block compensation value, and improves the phenomenon of horizontal streaks appearing in the display screen of the display.

[0081] S203: Determine a first compensation value based on the second gray level, the preset total compensation value, and the preset block compensation value.

[0082] Determine the first compensation value based on the second gray level, the preset total compensation value, and the preset block compensation value, using the following formula:

[0083] D = B + (A × C ÷ 128 - A), where A is the second gray level, B is the preset total compensation value, C is the preset block compensation value, and D is the first compensation value.

[0084] For example, if the second gray level is 64 gray, the preset total compensation value is 69 gray, and the preset block compensation value is 129, then D = 69 + (64 × 129 ÷ 128 - 64) = 69.5, and the first compensation value obtained is 69.5 gray.

[0085] It can be understood that using the above formula to determine the first compensation value improves the accuracy of determining the first compensation value.

[0086] S204: Adjust the first actual brightness corresponding to the second gray level according to the first compensation value to reduce the difference between the brightness corresponding to the first gray level and the first actual brightness.

[0087] Please refer to Figure 3 , Figure 3 which is a schematic structural diagram of a display device provided by an embodiment of the present application. Based on the above system architecture, the device can be a server or a module in the server. The device 300 at least includes: an acquisition module 301 and a processing module 302; where:

[0088] The acquisition module 301 is used to obtain the mixed-color picture of the display and determine its refresh rate. The mixed-color picture includes the first gray level and the second gray level;

[0089] The processing module 302 is used to determine the preset total compensation value and the preset block compensation value according to the refresh rate; determine the first compensation value based on the second gray level, the preset total compensation value, and the preset block compensation value; and adjust the first actual brightness corresponding to the second gray level according to the first compensation value to reduce the difference between the brightness corresponding to the first gray level and the first actual brightness.

[0090] In a possible example, the processing module 302 divides the refresh rate into multiple preset intervals according to the magnitude of the refresh rate; and determines a preset total compensation value and a preset block compensation value for each preset interval.

[0091] In a possible example, the processing module 302 determines a first preset voltage according to the preset interval; and outputs a preset total compensation value and a preset block compensation value according to the first preset voltage.

[0092] In a possible example, the processing module 302 obtains a first screen of the display, the first screen includes a plurality of block data, and the block data includes red-green sub-pixels, red-blue sub-pixels, and green-blue sub-pixels; and analyzes the brightness of the red-green sub-pixels, the brightness of the red-blue sub-pixels, and the brightness of the green-blue sub-pixels of each block data of the first screen.

[0093] In a possible example, when the red-green sub-pixels are bright, the red-blue sub-pixels are bright, and the green-blue sub-pixels are bright and have the same brightness, and when the proportion of the red-green sub-pixels in all the sub-pixels of the block data is greater than a first threshold, or when the proportion of the red-blue sub-pixels in all the sub-pixels of the block data is greater than the first threshold, or when the proportion of the green-blue sub-pixels in all the sub-pixels of the block data is greater than the first threshold, the processing module 302 determines that the first screen is a mixed-color screen.

[0094] In a possible example, the processing module 302 determines the first threshold to be 80%.

[0095] In a possible example, the processing module 302 calculates a first compensation value using the following formula: D = B + (A × C ÷ 128 - A), where A is the gray scale of the second row, B is the preset total compensation value, C is the preset block compensation value, and D is the first compensation value.

[0096] Please refer to Figure 4 , Figure 4 which is a structural diagram of a display device provided by an embodiment of the present application. As Figure 4 shown, Figure 4 the device 400 shown includes a processor 401, a memory 402, a communication interface 404, and one or at least one program 403. The above-mentioned memory 402 is used to store computer instructions, the processor 401 is used to call the computer instructions to execute the method as described above, the above-mentioned one or at least one program 403 is stored in the above-mentioned memory 402, and is configured to be executed by the above-mentioned processor 401. The above-mentioned program 403 includes instructions for performing the following steps:

[0097] Obtain a mixed-color screen of the display and determine its refresh rate. The mixed-color screen includes a first row gray scale and a second row gray scale;
