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 making any creative effort, shall fall within the protection scope of the present application. Furthermore, it should be understood that the detailed description and specific examples, while indicating exemplary embodiments of the invention, are given by way of illustration and explanation only, and are not intended to limit the scope of the invention.
The embodiment of the application provides a display panel drive debugging method, a display device and a storage medium. The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
An embodiment of the present application provides a display panel driver debugging method, as shown in fig. 1, the display panel driver debugging method mainly includes the following steps:
s100, acquiring the gray-scale value of the pixel on the current row and the gray-scale value of the pixel on the next row of the display panel.
The display area of the display panel comprises a plurality of pixels distributed in an array mode, and different display requirements can be achieved through adjustment and mutual matching of gray-scale values of the pixels. The display panel adopts the mode of line-by-line driving to charge pixels of each line in the use process, and the charging voltage of the display panel can be set by acquiring the gray scale value of the pixels of the current line and the gray scale value of the pixels of the next line of the display panel, so that the display effect of the display panel is ensured.
S200, determining the gray-scale value of the overdriven pixel of the initial line according to the gray-scale value of the pixel of the current line and the gray-scale value of the pixel of the next line.
When the display panel is charged line by line, an initial line overdrive pixel gray-scale value is set according to the current line pixel gray-scale value and the next line pixel gray-scale value, and then a current charging voltage is set according to the initial line overdrive pixel gray-scale value so as to ensure the display effect of the display panel.
When the gray-scale values of the pixels in the current row are used as the abscissa and the gray-scale values of the pixels in the next row are used as the ordinate, a row overdrive pixel gray-scale value table is established, and when the gray-scale values of the pixels in the initial row are obtained, the corresponding gray-scale values of the pixels in the initial row can be locked only according to the gray-scale values of the pixels in the current row and the gray-scale values of the pixels in the next row.
If the gray-scale value of the pixel of the current row is the same as the gray-scale value of the pixel of the next row, the gray-scale value of the pixel of the initial overdriven row is the same as the gray-scale value of the pixel of the current row and the gray-scale value of the pixel of the next row, and the charging requirement can be met without adjusting the gray-scale value of the pixel of the initial overdriven row in the charging process.
If the gray scale value of the pixels in the current row is different from the gray scale value of the pixels in the next row, when the pixels in the current row are charged to the pixels in the next row, the gray scale value of the overdriven pixels in the initial row is theoretically the same as the gray scale value of the pixels in the next row, but the actual charging condition may be different from the theoretical charging condition because the charging needs a certain time, and at the moment, the gray scale value of the overdriven pixels in the initial row needs to be adjusted, so that the display effect of the display panel is prevented from being influenced due to insufficient charging.
S300, controlling the display panel to display a first display picture according to the gray-scale value of the current row of pixels and the gray-scale value of the initial row of overdriven pixels.
The display frame of the display panel is composed of a plurality of rows of pixels, each row of pixels corresponds to a respective pixel gray-scale value, and different display frames can be obtained through setting the pixel gray-scale values of the rows of pixels. In this embodiment, the first display frame is composed of the gray scale values of the pixels in the current row and the gray scale values of the overdriven pixels in the initial row, that is, the gray scale values of the pixels distributed in the array in the first display frame only include the gray scale values of the pixels in the current row and the gray scale values of the overdriven pixels in the row. Different first display pictures can be presented by different arrangement modes of the gray-scale values of the pixels of the current row and the gray-scale values of the overdrive pixels of the initial row.
It should be noted that, in the embodiment of the present application, the gray scale values of the pixels in each row in the first display frame are alternately composed of the gray scale values of the pixels in the current row and the gray scale values of the overdrive pixels in the initial row. The first display frame is a line-stripe display frame because the gray scale values of the pixels in the current line are different from the gray scale values of the pixels in the initial line.
S400, controlling the display panel to display a second display picture according to the gray-scale values of the pixels in the current row and the gray-scale values of the pixels in the next row.
The gray-scale values of the pixels in the current row and the gray-scale values of the pixels in the next row are relatively stable values, and the second display frame formed based on the gray-scale values of the pixels in the current row and the gray-scale values of the pixels in the next row is also a relatively stable display frame. That is, the display panel driving debugging method in the embodiment of the present application can use the second display picture as a reference picture, thereby facilitating adjustment of the gray-scale value of the overdriven pixel in the initial row.
And S500, determining a target row overdrive pixel gray-scale value according to the first display picture and the second display picture.
After a first display picture and a second display picture are obtained through a current row pixel gray-scale value, a next row pixel gray-scale value and an initial row overdrive pixel gray-scale value, the initial row overdrive pixel gray-scale value is debugged according to the relation between the first display picture and the second display picture to obtain a target row overdrive pixel gray-scale value, so that the adjustment of the charging voltage of the display panel is realized, and the display effect of the display panel is ensured.
In the embodiment of the application, the display panel driving debugging method controls the display panel to display a first display picture according to the current row pixel gray-scale value and the initial row overdrive pixel gray-scale value of the display panel, controls the display panel to display a second display picture according to the current row pixel gray-scale value and the next row pixel gray-scale value, and obtains the target row overdrive pixel gray-scale value of the display panel according to the first display picture and the second display picture so as to debug the initial row overdrive pixel gray-scale value, so that the actual charging voltage of the display panel is closer to the target driving voltage, the insufficient charging of the display panel is improved, and the display effect of the display panel is improved.
Optionally, when the display panel is controlled to display the first display screen according to the gray-scale value of the current row of pixels and the gray-scale value of the overdrive pixel of the initial row, the method mainly includes the following steps:
firstly, the display panel is controlled to display a plurality of first sub-display frames according to the gray-scale value of the pixels on the current line, and each first sub-display frame comprises at least one line of first pixels. After the gray-scale value of the pixels of the current line is obtained, the gray-scale value is transmitted to the control end of the display panel, the gray-scale value of the pixels of partial lines in the pixels of the lines of the display panel is controlled to be the same as the gray-scale value of the pixels of the current line, and a plurality of first sub-display pictures are formed after the gray-scale value is displayed.
The first sub-display frames are line-stripe display frames, each first sub-display frame comprises at least one line of first pixels, and the gray-scale value of each sub-pixel in the first pixels is equal to the gray-scale value of the current line of pixels. That is, the display chromaticity of each of the first sub-display frames is the same, but there may be a difference in the size of the display area, and the size of the display area is determined by the number of rows of the first pixels included in each of the first sub-display frames.
And then, controlling the display panel to display a plurality of second sub-display frames according to the gray-scale value of the overdriven pixels of the initial line, wherein each second sub-display frame comprises at least one line of second pixels. After the gray-scale value of the overdriven pixels of the initial row is obtained, the gray-scale value is transmitted to the control end of the display panel, the gray-scale value of the pixels of the rest rows in the pixels of the multiple rows of the display panel is controlled to be the same as the gray-scale value of the overdriven pixels of the initial row, and a plurality of second sub-display pictures are formed after display.
The second sub-display frames are line stripe display frames, each second sub-display frame comprises at least one line of second pixels, and the gray-scale value of each sub-pixel in each second pixel is equal to the gray-scale value of the overdrive pixel in the initial line. That is, the display chromaticity of each second sub-display frame is the same, but there may be a difference in the size of the display area, and the size of the display area is determined by the number of rows of the second pixels included in each second sub-display frame.
Optionally, the plurality of first sub-display frames and the plurality of second sub-display frames are alternately arranged, that is, the second sub-display frames are disposed on two sides of the first sub-display frame, and the first sub-display frames are disposed on two sides of the second sub-display frame. Through the alternative arrangement of the first sub-display picture and the second sub-display picture, the phenomenon that the display chromaticity of the first display picture is uneven due to the fact that the occupied area of the first sub-display picture or the second sub-display picture is too large and the determination of the gray-scale value of the overdriven pixel of the subsequent target row is not facilitated can be avoided.
Optionally, the number of rows of the first pixels in each of the first sub-display frames is equal, that is, the display area occupied by each of the first sub-display frames is the same, and this arrangement makes the plurality of first sub-display frames uniformly distributed in the display area, so as to avoid that the display chromaticity difference of the first sub-display frame is too large and the display effect of the first sub-display frame is affected due to too small or too large area occupied by the first sub-display frame at a certain position.
Optionally, the number of rows of the second pixels in each second sub-display picture is equal, that is, the display area occupied by each second sub-display picture is the same, and this arrangement makes the plurality of second sub-display pictures uniformly distributed in the display area, so as to avoid that the display chromaticity difference of the second sub-display pictures is too large and the display effect of the first display picture is affected due to too large or too small area occupied by the second sub-display picture at a certain position.
In some embodiments, the number of rows of the first pixels in each of the first sub-display frames is equal, and the number of rows of the second pixels in each of the second sub-display frames is equal, that is, the first pixels and the second pixels are uniformly distributed, and the display chromaticities of the first pixels and the second pixels are also uniformly distributed, which helps to improve the uniformity of the display chromaticities of the first display frames.
In other embodiments, the number of rows of the first pixels in each first sub-display frame is equal to the number of rows of the second pixels in each second sub-display frame, that is, the first pixels and the second pixels are uniformly distributed as a whole, and the display areas occupied by each first sub-display frame and each second sub-display frame are the same, so that the distribution manner can further improve the uniformity of the display chromaticity of the first display frame.
It should be noted that the number of rows of the first pixels in each first sub-display frame and the number of rows of the second pixels in each second sub-display frame can be adjusted according to actual display requirements.
When the gray-scale values of the pixels in the current row and the gray-scale values of the overdriven pixels in the initial row are distributed, the number of rows of the first pixels in each first sub-display frame can be gradually increased or gradually decreased or in any other feasible distribution mode, and the number of rows of the second pixels in each second sub-display frame can also be gradually increased or gradually decreased or in any other feasible distribution mode, so that only the first sub-display frames and the second sub-display frames are required to be distributed alternately and meet the display requirements.
Optionally, in this embodiment of the application, each first sub display frame includes a row of first pixels, and each second sub display frame includes a row of second pixels. That is, the first pixels and the second pixels are alternately distributed row by row, and the corresponding gray-scale values of the pixels on the current row and the gray-scale values of the pixels on the initial row are alternately distributed.
In some embodiments, the gray scale values of the odd-numbered rows of pixels of each row of pixels distributed in the array of the display panel are the gray scale values of the current-row pixels, the gray scale values of the even-numbered rows of pixels are the gray scale values of the initial-row overdrive pixels, and the display uniformity of the first display frame can be improved to the greatest extent by the row-by-row alternate distribution of the gray scale values of the current-row pixels and the gray scale values of the initial-row overdrive pixels.
In other embodiments, the gray scale values of the pixels in the even rows of the pixels in each row of the display panel distributed in an array are the gray scale values of the pixels in the current row, the gray scale values of the pixels in the odd rows are the gray scale values of the overdrive pixels in the initial row, and the display uniformity of the first display frame can be improved to the greatest extent by the alternate line-by-line distribution of the gray scale values of the pixels in the current row and the gray scale values of the overdrive pixels in the initial row.
Optionally, when the display panel is controlled to display the second display screen according to the gray-scale values of the pixels in the current row and the gray-scale values of the pixels in the next row, the method mainly includes the following steps:
first, a pure gray value is determined according to the gray values of the pixels in the current row and the gray values of the pixels in the next row. The pure gray level value is obtained by calculation according to the gray level value of the current row of pixels and the gray level value of the next row of pixels, and the pure gray level value is an average value of the gray level value of the current row of pixels and the gray level value of the next row of pixels in the embodiment of the application.
It should be noted that the pure gray scale value is a design parameter for obtaining the second display frame in the embodiment of the present application, and the specific calculation method thereof can be adjusted according to the change of the display panel driving debugging method. In addition, the second display picture is used as a reference picture for debugging the overdrive pixels of the initial line, the calculation method of the pure gray-scale value can be adjusted according to the design requirement of the reference picture, and the design of the pure gray-scale value can meet the display requirement of the second display picture.
And then, controlling the display panel to display a second display picture according to the pure gray-scale value. The second display frame is a pure gray scale frame, that is, when the display panel displays the second display frame, the gray scale values of the pixels in each row distributed in the array in the display area of the display panel are all pure gray scale values, so the second display frame can be used as a reference display frame in the display panel driving debugging method in the embodiment of the present application.
Optionally, as shown in fig. 2, when determining the target row overdrive pixel gray-scale value according to the first display frame and the second display frame, the method mainly includes the following steps:
s510, acquiring a first brightness value of a first display picture.
After the display panel is controlled to display the first display picture according to the pixel gray-scale value of the current line and the pixel gray-scale value of the overdrive line, a first brightness value of the first display picture needs to be acquired. The embodiment of the application mainly measures the first brightness value of the first display picture through an optical instrument, namely the first brightness value of the current first display picture can be obtained after the display panel displays the first display picture.
It should be noted that, when the first brightness value of the first display image is obtained, the first brightness value can be directly observed by human eyes without using an instrument, and then compared with the standard brightness value to determine the range to which the first brightness value belongs. Although the accuracy of the first brightness value obtained by adopting the method is lower than that of the first brightness value obtained by using the optical instrument, the equipment requirement and the production cost can be reduced, and the method is suitable for application situations with relatively lower precision requirement.
S520, acquiring a second brightness value of the second display picture.
And after the display panel is controlled to display the second display picture according to the pixel gray-scale value of the current row and the pixel gray-scale value of the next row, a second brightness value of the second display panel needs to be acquired. The embodiment of the application mainly measures the second brightness value of the second display picture through an optical instrument so as to quickly and accurately acquire the second brightness value of the current second display picture.
It should be noted that, when the second luminance value of the second display image is acquired, the second luminance value can be directly observed by human eyes and then compared with the standard luminance value to determine the range to which the second luminance value belongs. Although the accuracy of the second brightness value obtained by adopting the method is lower than that of the second brightness value obtained by using an optical instrument, the second display picture is a pure gray scale picture, so that the brightness value of the second display picture is relatively simple to observe, the method has higher feasibility under the condition of relatively low precision requirement, and the equipment requirement and the production cost can be reduced.
S530, determining the gray-scale value of the overdriven pixel of the target row according to the first brightness value and the second brightness value.
After a first brightness value of the first display picture and a second brightness value of the second display picture are obtained, the gray-scale value of the overdrive pixel of the initial row is debugged according to the mutual relation between the first brightness value and the second brightness value so as to determine the gray-scale value of the overdrive pixel of the target row.
Optionally, as shown in fig. 3, the determining the gray-scale value of the overdriven pixel of the target row according to the first luminance value and the second luminance value in step S530 mainly includes the following steps:
s531, calculating a difference value between the first brightness value and the second brightness value;
the first brightness value corresponds to a first display frame displayed by the display panel according to the current row pixel gray-scale value and the initial row overdrive pixel gray-scale value, and the second brightness value corresponds to a second display frame displayed by the display panel according to the current row pixel gray-scale value and the next row pixel gray-scale value, so that a difference exists between the first brightness value and the second brightness value, and the difference between the first brightness value and the second brightness value is derived from the magnitude of the initial row overdrive pixel gray-scale value. That is, the difference between the first luminance value and the second luminance value can be changed by adjusting the gray-scale value of the overdriven pixels in the initial row.
And S532, comparing the difference value with a first preset threshold value.
When judging whether the difference value between the first brightness value and the second brightness value meets the design requirement, whether the difference value is within the set first preset threshold value range needs to be judged, and the size and the judgment condition of the first preset threshold value can be adjusted according to the actual design requirement.
And S533, comparing the first brightness value with the second brightness value.
In addition to comparing the difference between the first luminance value and the second luminance value with the first preset threshold, the first luminance value and the second luminance value also need to be compared, and the magnitude relationship between the first luminance value and the second luminance value directly affects the adjustment mode of the overdrive pixels in the initial row.
S534, if the first brightness value is greater than the second brightness value and the difference value is greater than the first preset threshold value, the gray scale value of the overdriven pixels of the initial row is reduced until the difference value is less than or equal to the first preset threshold value.
When the difference between the first luminance value and the second luminance value is greater than the first preset threshold, it indicates that the difference between the first luminance value and the second luminance value exceeds the set range, and the gray scale value of the overdrive pixels in the initial row needs to be adjusted.
When the first luminance value is greater than the second luminance value, it indicates that the gray scale value of the initial row overdrive pixel is too large, the display panel is controlled to redisplay the first display image after the gray scale value of the initial row overdrive pixel needs to be reduced, if the first luminance value of the first display image is still greater than the second luminance value and the difference between the first luminance value and the second luminance value is greater than the first preset threshold value, the gray scale value of the initial row overdrive pixel needs to be reduced continuously to obtain a new gray scale value of the row overdrive pixel, and the process is repeated until the difference between the first luminance value and the second luminance value is less than or equal to the first preset threshold value.
At this time, the line overdrive pixel gray-scale value in the first display frame corresponding to the first brightness value is the target line overdrive pixel gray-scale value. And setting the charging voltage of the display panel according to the obtained target row overdrive pixel gray-scale value, so that the display effect of the display panel can be prevented from being influenced by insufficient charging of the display panel.
Optionally, as shown in fig. 4, the determining the target row overdrive pixel gray-scale value according to the first luminance value and the second luminance value in step S530 further includes the following steps:
s535, calculating a difference between the first luminance value and the second luminance value.
According to the sources of the first display frame and the second display frame corresponding to the first luminance value and the second luminance value, respectively, the difference between the first luminance value and the second luminance value is mainly derived from the gray scale value of the overdrive pixels in the initial row, and the difference between the first luminance value and the second luminance value can be changed by adjusting the gray scale value of the overdrive pixels in the initial row.
And S536, comparing the difference value with a second preset threshold value.
When judging whether the difference value between the first brightness value and the second brightness value meets the design requirement, whether the difference value is within a set second preset threshold value range needs to be judged, and the size and the judgment condition of the second preset threshold value can be adjusted according to the actual design requirement.
Wherein the second preset threshold and the first preset threshold can be equal or unequal. In the actual debugging process, the gray-scale value of the pixel of the next row is larger than the gray-scale value of the pixel of the current row, and especially when the gray-scale value of the pixel of the current row is also larger, even if the gray-scale value of the overdrive pixel of the initial row is debugged in a smaller range, the larger change of the brightness value can be caused, and in order to ensure that the gray-scale value of the overdrive pixel of the debugged row is closer to the gray-scale value of the overdrive pixel of the target row, the smaller the setting ranges of the first preset threshold and the second preset threshold are, the better the setting ranges are, so as to ensure that the gray-scale value of the overdrive pixel of the initial row is debugged more accurately.
And S537, comparing the first brightness value with the second brightness value.
S538, if the first brightness value is smaller than the second brightness value and the difference value is larger than a second preset threshold value, the gray scale value of the overdriven pixels of the initial row is increased until the difference value is smaller than or equal to the second preset threshold value.
When the difference between the first luminance value and the second luminance value is greater than the second preset threshold, it indicates that the difference between the first luminance value and the second luminance value exceeds the set range, and the gray scale value of the overdrive pixels in the initial row needs to be adjusted.
When the first brightness value is smaller than the second brightness value, it is indicated that the gray scale value of the initial row of overdriven pixels is too small, the display panel is controlled to redisplay the first display image after the gray scale value of the initial row of overdriven pixels needs to be increased, if the first brightness value of the first display image is still smaller than the second brightness value and the difference between the first brightness value and the second brightness value is larger than the first preset threshold value, the gray scale value of the initial row of overdriven pixels needs to be continuously increased to obtain a new gray scale value of the row of overdriven pixels, and the process is repeated until the difference between the first brightness value and the second brightness value is smaller than or equal to the second preset threshold value.
At this time, the line overdrive pixel gray-scale value in the first display frame corresponding to the first brightness value is the target line overdrive pixel gray-scale value. And setting the charging voltage of the display panel according to the obtained target row overdrive pixel gray-scale value, so that the display effect of the display panel can be prevented from being influenced by insufficient charging of the display panel.
Optionally, when the gray-scale value of the target row overdrive pixel is determined according to the first brightness value and the second brightness value, after the first brightness value and the second brightness value are obtained, a difference between the first brightness value and the second brightness value is calculated, and the difference is compared with a third preset threshold, if the difference is smaller than or equal to the third preset threshold, the gray-scale value of the initial row overdrive pixel can be determined to be the gray-scale value of the target row overdrive pixel, and the gray-scale value does not need to be adjusted.
The third preset threshold can be the same as the first preset threshold or the second preset threshold, the specific size of the third preset threshold can be adjusted according to actual design requirements, and only the third preset threshold, the first preset threshold and the second preset threshold need to be set to ensure that the finally obtained target row overdrive pixel gray scale value meets the actual design requirements, so that the problem of insufficient charging of the display panel is avoided, and the normal display effect of the display panel is ensured.
