[0062] It should be noted that Figure 1 The scenario diagram of the display panel image compensation system shown is merely an example. The display panel image compensation system and scenario described in the embodiment of the present application are intended to more clearly illustrate the technical solution of the embodiment of the present application, and do not constitute a limitation on the technical solution provided in the embodiment of the present application. A person of ordinary skill in the art can appreciate that with the evolution of the display panel image compensation system and the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

[0063] First, a display panel image compensation method is provided in an embodiment of the present application. The executor of the display panel image compensation method is a display panel image compensation device. The display panel image compensation device is applied to an electronic device. The display panel image compensation method includes: dividing the initial image of the display panel to be compensated to obtain multiple first images to be compensated; determining a first brightness value corresponding to each first image in the multiple first images to obtain multiple first brightness values; determining a highlight image and a low-dark image in the multiple first images according to the multiple first brightness values ​​and a preset brightness threshold; adjusting the brightness corresponding to the highlight image and the low-dark image respectively to obtain a second brightness value corresponding to the highlight image and a third brightness value corresponding to the low-dark image; and compensating the initial image according to the second brightness value and the third brightness value.

[0064] See also Figure 2 , Figure 2 FIG. 1 is a flow chart of an embodiment of a display panel image compensation method provided by an embodiment of the present application. Figure 2 As shown, the display panel image compensation method includes the following steps:

[0065] 21. Divide the initial picture of the display panel to be compensated to obtain a plurality of first pictures to be compensated.

[0066] The display panel image compensation method provided in the embodiment of the present application is generally applied to a display panel production line. In order to ensure the production efficiency of the display panel, it is necessary to compensate the image of the display panel in a relatively short time.

[0067] The display panel production line is usually equipped with a camera or other equipment for capturing the display panel display screen. The camera can capture the current display screen of the display panel and compensate the display panel according to the captured current display screen. In the embodiment of the present application, the initial screen of the display panel to be compensated needs to be divided to obtain multiple first screens to be compensated.

[0068] Since the display panel can be divided into a plurality of different display areas, and different display areas correspond to different first images to be compensated; and since different display areas display different first images, different compensations are usually performed on different first images.

[0069] 22. Determine a first brightness value corresponding to each first picture in a plurality of first pictures to obtain a plurality of first brightness values.

[0070] 23. Determine a highlight image and a dim image among the plurality of first images according to the plurality of first brightness values ​​and a preset brightness threshold.

[0071] In the embodiment of the present application, the purpose of acquiring multiple first images is to acquire first brightness values ​​corresponding to each of the multiple first images, so as to determine grayscales corresponding to each of the multiple first images. Different grayscales usually correspond to different gamma compensations.

[0072] After determining the first brightness values ​​corresponding to each of the multiple first images, it is necessary to further determine whether the first image is a high-brightness image or a low-darkness image based on the first brightness value; this is because in an embodiment of the present application, different adjustments need to be made to the high-brightness image and the low-darkness image.

[0073] Specifically, any first brightness value among multiple first brightness values ​​can be used as the target first brightness value; if the target first brightness value is greater than the preset brightness threshold, the image corresponding to the target first brightness value is a highlighted image; if the target first brightness value is less than the preset brightness threshold, the image corresponding to the target first brightness value is a dimmed image.

[0074] Generally speaking, the larger the grayscale of the display panel, the larger the corresponding brightness value; therefore, in other embodiments of the present application, after obtaining multiple first brightness values, the multiple first brightness values ​​can also be converted into grayscale, and the high-brightness image and the low-darkness image can be judged according to the grayscale. Similarly, the converted grayscale value and the preset grayscale threshold can be used to judge the high-brightness image and the low-darkness image.

[0075] In a specific embodiment, the grayscales corresponding to the first images are all within the grayscale range of 0-255, and the preset grayscale threshold can be grayscale 128. This is because when the grayscale is within 0-128, when the grayscale increases, the corresponding brightness increase trend is low; and when the grayscale is within the range of 129-255, when the grayscale increases, the corresponding brightness increase trend is high.

[0076] If the grayscale corresponding to the first picture is greater than 128, the first picture is considered to be a high-brightness picture; similarly, if the grayscale corresponding to the first picture is less than or equal to 128, the first picture is considered to be a low-darkness picture.

[0077] It should be noted that in the embodiments of the present application, both the preset brightness threshold and the preset grayscale threshold can be adjusted according to actual needs and are not specifically limited.

[0078] 24. Adjust the brightness corresponding to the highlighted image and the dimmed image respectively to obtain a second brightness value corresponding to the highlighted image and a third brightness value corresponding to the dimmed image.

[0079] like Figure 3 As shown, it is a schematic diagram of an embodiment of adjusting the brightness corresponding to the highlight image and the low-light image provided by the embodiment of the present application. In the embodiment of the present application, adjusting the brightness corresponding to the highlight image and the low-light image respectively to obtain the second brightness value corresponding to the highlight image and the third brightness value corresponding to the low-light image may include:

[0080] 31. Reduce the brightness corresponding to the highlighted image to obtain a second brightness value corresponding to the adjusted brightness of the highlighted image.

[0081] 32. Increase the brightness corresponding to the low-dark image to obtain a third brightness value corresponding to the low-dark image after the brightness is adjusted.

[0082] Specifically, in the embodiment of the present application, due to the different brightnesses corresponding to different pictures (or the different corresponding grayscales), the camera may be overexposed or underexposed when collecting brightness data. In the embodiment of the present application, the brightness of the low-light picture is increased and the brightness corresponding to the high-light picture is reduced to reduce the brightness difference between the high-light picture and the low-light picture. At this time, the camera is reused to collect the brightness values ​​corresponding to different pictures. Since the brightness difference between the high-light picture and the low-light picture is reduced, it is not easy to be overexposed or underexposed; making the collected brightness closer to the real brightness value.

[0083] It should be noted that, in the embodiment of the present application, the second brightness value after reduction is greater than or equal to the minimum brightness value among the plurality of brightness values; and the third brightness value is less than or equal to the maximum brightness value among the plurality of first brightness values. That is, regardless of increasing the brightness value or decreasing the brightness value, the adjusted brightness value needs to be within the brightness range corresponding to the maximum brightness value and the minimum brightness value among the first brightness values.

[0084] In an embodiment of the present application, there are multiple first brightness values, and there are also multiple second brightness values ​​and multiple third brightness values; and the sum of the number of the multiple second brightness values ​​and the number of the multiple third brightness values ​​is equal to the number of the multiple first brightness values.

[0085] 25. Compensate the initial image according to the second brightness value and the third brightness value.

[0086] The display panel image compensation method provided in the embodiment of the present application first divides the initial image to be compensated to obtain multiple first images to be compensated, and obtains the first brightness values ​​corresponding to each of the multiple first images respectively, so as to determine the highlight image and the low-dark image in the multiple first images according to the multiple first brightness values ​​and the preset brightness threshold; and respectively adjusts the brightness values ​​corresponding to the highlight image and the low-dark image to obtain the second brightness value corresponding to the highlight image and the third brightness value corresponding to the low-dark image, and finally compensates the initial image according to the adjusted second brightness value and the third brightness value. In the present application, only one acquisition is performed on the initial image to be compensated, which effectively reduces the time required for acquiring accurate grayscale data; and in the present application, the brightness values ​​of the highlight image and the low-dark image are adjusted respectively to reduce the brightness value difference between the highlight image and the low-dark image, so as to avoid overexposure or underexposure due to the large difference in brightness values ​​when acquiring brightness, thereby improving the accuracy of brightness value and grayscale acquisition.

[0087] like Figure 4 FIG. 1 is a flow chart of an embodiment of compensating according to the second brightness value and the third brightness value provided in an embodiment of the present application. Specifically, compensating the display panel according to the second brightness value and the third brightness value may include:

[0088] 41. Determine a first grayscale value corresponding to the highlighted image according to the second brightness value.

[0089] 42. Determine a second grayscale value corresponding to the dark picture according to the third brightness value.

[0090] 43. Compensate the initial image according to the first grayscale value and the second grayscale value.

[0091] Specifically, in the embodiment of the present application, by adjusting the brightness corresponding to the highlight image and the low-dark image, the brightness corresponding to the highlight image with higher accuracy is determined, so that the first grayscale value corresponding to the highlight image with higher accuracy can be obtained; similarly, for the low-dark image, the brightness corresponding to the low-dark image with higher accuracy is also determined, and then the second grayscale value corresponding to the low-dark image with higher accuracy is determined. After determining the grayscale values ​​corresponding to different images in the display panel with higher accuracy, the images can be compensated according to the grayscale values ​​with higher accuracy.

[0092] In the above embodiment, although the camera first determines the highlight image and the low-dark image based on the brightness of the image acquired for the first time, the brightness difference between the highlight image and the low-dark image is large, resulting in inaccurate brightness. Therefore, in the embodiment of the present application, the brightness of the highlight image and the low-dark image is adjusted to reduce the brightness difference between the two; at this time, the brightness of the two is acquired again. Since the brightness difference is small, the camera is not prone to overexposure or underexposure, and the brightness data acquired at this time is more accurate. Under the premise that the acquired brightness data is more accurate, the grayscale data corresponding to the brightness is also more accurate. At this time, the image is compensated according to the grayscale value with higher precision, and the compensation effect is better.

[0093] Specifically, in the field of display panels, the brightness corresponding to the adjusted picture is usually adjusted in multiples, so the adjusted brightness is a multiple of the brightness before adjustment. After obtaining the adjusted brightness value, 1 / n or n times the adjusted brightness value can be taken as the brightness value before adjustment. Among them, n is the multiple of the brightness adjustment, and n is usually a positive integer. After determining the brightness, the grayscale value corresponding to the brightness can be determined to compensate using the grayscale value.

[0094] In order to better implement the display panel image compensation method in the embodiment of the present application, based on the display panel image compensation method, the embodiment of the present application also provides a display panel image compensation device, such as Figure 5 As shown, Figure 5 This is a schematic diagram of the structure of an embodiment of a display panel image compensation device provided in an embodiment of the present application. The electric display panel image compensation device 500 includes:

[0095] The division module 501 is used to divide the initial picture of the display panel to be compensated to obtain a plurality of first pictures to be compensated.

[0096] The brightness determination module 502 is used to determine a first brightness value corresponding to each first picture in a plurality of first pictures to obtain a plurality of first brightness values.

[0097] The brightness comparison module 503 is used to determine the highlight images and the dim images among the multiple first images according to the multiple first brightness values ​​and the preset brightness threshold.

[0098] The brightness adjustment module 504 is used to adjust the brightness corresponding to the highlight image and the dim image respectively, to obtain a second brightness value corresponding to the highlight image and a third brightness value corresponding to the dim image.

[0099] The compensation module 505 is used to compensate the initial image according to the second brightness value and the third brightness value.

[0100] The display panel image compensation device provided in the embodiment of the present application first divides the initial image to be compensated to obtain multiple first images to be compensated, and obtains the first brightness values ​​corresponding to each of the multiple first images respectively, so as to determine the highlight image and the low-dark image in the multiple first images according to the multiple first brightness values ​​and the preset brightness threshold; and adjusts the brightness values ​​corresponding to the highlight image and the low-dark image respectively to obtain the second brightness value corresponding to the highlight image and the third brightness value corresponding to the low-dark image, and finally compensates the initial image according to the adjusted second brightness value and the third brightness value. In the present application, only one acquisition is performed on the initial image to be compensated, which effectively reduces the time required for acquiring accurate grayscale data; and in the present application, the brightness values ​​of the highlight image and the low-dark image are adjusted respectively to reduce the brightness value difference between the highlight image and the low-dark image, so as to avoid overexposure or underexposure due to the large difference in brightness values ​​when acquiring brightness, thereby improving the accuracy of brightness value and grayscale acquisition.

[0101] In some embodiments, the brightness contrast module 503 may be specifically used for:

[0102] Taking any first brightness value among the plurality of first brightness values ​​as a target first brightness value;

[0103] If the target first brightness value is greater than the preset brightness threshold, the image corresponding to the target first brightness value is a highlighted image; if the target first brightness value is less than the preset brightness threshold, the image corresponding to the target first brightness value is a dimmed image.

[0104] In some embodiments, the brightness adjustment module 504 may be specifically used to:

[0105] The brightness corresponding to the highlighted image is reduced to obtain a second brightness value corresponding to the adjusted brightness of the highlighted image; the brightness corresponding to the dimmed image is increased to obtain a third brightness value corresponding to the adjusted brightness of the dimmed image.

[0106] The second brightness value is greater than a minimum brightness value among the multiple first brightness values, and the third brightness value is less than a maximum brightness value among the multiple first brightness values.

[0107] In some embodiments, the compensation module 505 may be specifically used to:

[0108] According to the second brightness value, a first grayscale value corresponding to the bright picture is determined; according to the third brightness value, a second grayscale value corresponding to the dark picture is determined; and according to the first grayscale value and the second grayscale value, the initial picture is compensated.

[0109] The embodiment of the present application also provides an electronic device, the electronic device includes a display panel and integrates any one of the electronic display panel image compensation devices provided in the embodiment of the present application.
