[0051] In order to make the objectives, technical solutions and advantages of the present disclosure more clear and understandable, the present disclosure will be further described in detail below with reference to specific embodiments and the accompanying drawings.

[0052] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should have the ordinary meanings understood by those of ordinary skill in the art to which the present disclosure belongs. The terms "first", "second" and similar terms used in the embodiments of the present disclosure do not denote any order, quantity or importance, but are only used to distinguish different components. The terms such as "including" or "comprising" mean that the elements or objects appearing before this word cover the elements or objects listed after this word and their equivalents, without excluding other elements or objects. The terms such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms such as "upper", "lower", "left" and "right" are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0053] In response to the existing problems of uneven brightness and mura phenomenon, the currently widely adopted method is the Demura compensation method. The Demura compensation method usually takes several grayscale pictures by a high-resolution and high-precision CCD camera; then analyzes the color distribution characteristics of the pixels in the display picture according to the data collected by the camera, and identifies the Mura according to relevant algorithms; generates Demura data, that is, Mura compensation data, according to the Mura data and the corresponding Demura compensation algorithm; and burns the Demura data into the Flash ROM for use in Mura compensation when displaying the picture.

[0054] The inventors found that even if the existing Demura compensation method is used to process the boundary between the imaging area and the normal area, good improvement cannot be obtained, and there are still problems with brightness differences.

[0055] Combined with Figure 1As shown, the square area is shown as the first display area, and the circular area is shown as the second display area. As shown in the figure, in the display module, the second display area emits light, the first display area is dark, and there is a brightness difference at the boundary between the first display area and the second display area. During filtering, the boundary areas between the first display area and the second display area will affect each other, as shown in the difference before and after Gaussian filtering. After filtering, the average value of the edge on the side of the first display area will be increased, and the average value of the edge on the side of the second display area will be decreased. Correspondingly, during the post-processing compensation of the Demura algorithm, the average value of the edge on the side of the first display area will be decreased, and the average value of the edge on the side of the second display area will be increased, resulting in a final display screen showing a bright inner ring and a dark outer ring. This phenomenon is verified by comparing the Gaussian filtering with the difference before filtering as shown in the figure, such as Figure 1 as shown. And this solution aims to solve this problem. Among them, the Demura algorithm can refer to a method for solving the Mura phenomenon, which reduces the brightness of the brighter display area and increases the brightness of the darker display area to make the full-screen display uniform.

[0056] In view of this, the embodiments of the present disclosure provide a compensation method for a display module, which can improve the aforementioned bright and dark ring phenomenon to a certain extent.

[0057] Figure 2A The schematic diagram of the display module 200 according to the embodiments of the present disclosure is shown.

[0058] As Figure 2A shown, the display module 200 may include a first display area 202 and a second display area 204, and the first display area 202 may at least partially surround the second display area 204. In some embodiments, the second display area 204 may be the area where the under-screen camera is set, and the first display area 202 may be the area where the under-screen camera is not set. It can be known that when the under-screen camera is set in the second display area 204, the display pictures corresponding to the first display area 202 and the second display area 204 may have uneven brightness.

[0059] To solve this problem, the embodiments of the present disclosure provide a compensation method for a display module. Figure 2B The schematic flow diagram of the exemplary compensation method provided by the embodiments of the present disclosure is shown.

[0060] See Figure 2B shown; the compensation method may include the following steps:

[0061] S1: Receive the display data of the display module, where the display data includes the first display data of the first display area and the second display data of the second display area;

[0062] S2: extracting first data from the first display data, and replacing the second display data in the display data based on the first data, to obtain a first array corresponding to the display data;

[0063] S3: extracting second data from the second display data, and generating third display data of a boundary area between the first display area and the second display area based on the second data, to obtain a second array including the second display data and the third display data;

[0064] S4: performing filtering processing on the first array and the second array respectively to obtain a third array corresponding to the first array and a fourth array corresponding to the second array;

[0065] S5: Compensate the third array based on the fourth array to obtain target display data.

[0066] In this example, the first display area is the FDC area, and the second display area is the Normal area;

[0067] Among them, the FDC area indicates the camera area, and the Normal area indicates the regular area of ​​the screen.

[0068] The compensation method provided in this embodiment first replaces the first data extracted from the first display area into the second display area, performs a data replacement and generates a first array; then replaces the second data extracted from the second display data into the boundary area, performs a secondary data replacement and generates a second array; then filters the first array and the second array to obtain the corresponding third array and fourth array after filtering, and compensates the processed third and fourth arrays to form the display data after the display module completes the compensation; it can improve the brightness difference at the boundary and improve the bright and dark ring problem between different display areas; it can obtain a better compensation effect and optimize the display effect of the boundary area.

[0069] In some embodiments, the display data may be image data obtained by taking a picture with a camera. In some optional embodiments, step S1 may further select and adopt at least one of display area extraction processing, moiré removal processing and particle removal processing to pre-process the display data, thereby obtaining pre-processed display data, which may include first display data of the first display area and second display data of the second display area. Optionally, the display data may be a pixel grayscale value.

[0070] Further integration Figure 3 As shown, in some optional embodiments, the step S2 of extracting the first data from the first display data may further include:

[0071] Extract the first data of the first display area that is in a parallel position with the second display area from the first display data.

[0072] As Figure 3 shown, the rounded rectangle area can be the first display area, the circular area can be the second display area, and the dotted circle area represents the first data extracted from the first display data and used to replace the second display area.

[0073] Among them, in some optional embodiments, first extract the information of the brightness difference of the first display area, calculate the gray level to be compensated by analyzing the extracted information, the first display data is the pixel gray level representing the brightness of the first display area, and the second display data is the pixel gray level representing the brightness of the second display area.

[0074] The first data extracted from the parallel position can reduce the influence of the IR voltage drop, and then, in the form of discrete data, it is saved as the first array; and the replacement of the first data is to separately save the data (the first data area) at a specific address of the array to another array for filling, and obtain and generate the replaced first array.

[0075] The IR voltage drop is shown as: the deviation caused by I (current) and R (resistance).

[0076] Further combined with Figure 4 shown, in some optional embodiments, the S3 step of generating the third display data of the boundary area between the first display area and the second display area based on the second data may further include the following steps:

[0077] Expand the target number of pixels outward from the periphery of the second display area to determine the boundary area.

[0078] It should be noted that the boundary is the junction of the second display area and the first display area, and its boundary area is the area generated by expanding from the first circle of pixels to the first display area outside according to a pixel block of a certain size.

[0079] Among them, based on the second data extracted from the second display data, the third display data is generated in the above-expanded manner as the boundary area, and then a secondary replacement is performed. The secondary replacement is the replacement and coverage of the boundary area, and the second array is formed by combining the third display data of the boundary area and the second display data.

[0080] In some optional embodiments, it should be noted that the first array includes the first gray level values corresponding to the pixel points in the first display area and the second display area; similarly, the second array includes the second gray level values corresponding to the pixel points in the second display area and the boundary area.

[0081] Combined with Figure 5 shown, where step S4 further includes:

[0082] S401: For the pixel points in the first display area and the second display area, perform weighted averaging on the first gray scale values of the pixel points within the neighborhood of the pixel points through Gaussian filtering;

[0083] S402: Use the calculated weighted average value as the new first gray scale value of the corresponding pixel point, and further obtain the third array.

[0084] Perform filtering once in the above manner, and then filter the pixel points of the first array in the first display area and the second display area after the first replacement into the third array.

[0085] In some alternative embodiments, based on the above embodiments, step S4 may further include:

[0086] S403: For the pixel points in the second display area and the boundary area, perform weighted averaging on the second gray scale values of the pixel points within the neighborhood of the pixel points through Gaussian filtering;

[0087] S404: Use the calculated weighted average value as the new second gray scale value of the corresponding pixel point, and further obtain the fourth array.

[0088] After the first filtering, perform second filtering on the pixel points of the second array generated from the second display area and the boundary area after the second replacement, and further generate the fourth array.

[0089] Combined with Figure 6 As shown, in some alternative embodiments, based on the above embodiments, step S5 may further include:

[0090] Use the fourth array to replace the data corresponding to the pixel points in the second display area and the boundary area in the third array to obtain the target display data.

[0091] Further combined with Figure 7 As shown, on the left is the effect diagram without performing Demura processing using the above solution, and there are still bright and dark rings. While on the right is the effect diagram after edge optimization and compensation using this solution, making the bright and dark rings between the two boundaries invisible.

[0092] The compensation method of the display module provided in this embodiment first replaces the first data extracted from the first display area into the second display area, performs a data replacement once and generates a first array; then replaces the second data extracted from the second display data into the boundary area, performs a secondary data replacement and generates a second array; then performs a filtering process on the first array and the second array, and after filtering, obtains the corresponding third array and fourth array, and compensates the processed third and fourth arrays to form the display data after the display module is compensated; it can improve the brightness difference existing at the boundary and optimize the display effect of the boundary area.
