[0028] Various embodiments will now be described in detail with reference to the accompanying drawings, which are provided as exemplary examples of the present disclosure to enable those skilled in the art to implement the present disclosure.

[0029] It should be noted that the following figures and examples are not intended to limit the scope of the present disclosure.

Further, various embodiments include, by way of illustration, equivalents now and in the future that are equivalent to the components referred to herein.

[0030] Unless the context clearly indicates otherwise, the singular form of the words used in this document and the appended claims includes the plural form, and vice versa. Thus, when referring to the singular, the plural form of the corresponding term is generally included. Similarly, the terms "comprise", "include", "contain" and "have" and their grammatical variations are intended to be inclusive and indicate that there may be additional elements in addition to the listed elements. Where the term "example" is used in this document, particularly when it is located after a group of terms, the "example" is merely exemplary and illustrative and should not be considered exclusive or extensive. The terms "first", "second", "third", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance and formation order.

[0031] When the image displayed on a display device switches rapidly, the drive voltage (i.e., display signal) applied to the display pixels of the display device must also change rapidly to ensure that the brightness of the display device changes with the image. However, when the drive voltage varies widely, the actual drive voltage applied to the display pixels cannot reach the target drive voltage. As a result, the brightness cannot reach the target brightness, ultimately resulting in smearing.

[0032] Figure 1 is a schematic block diagram of a display device according to an embodiment of the present disclosure. Figure 1 As shown, the display device may include at least one display area 12, and the display area 12 may include at least one display pixel 122, wherein the display pixel 122 emits light under the drive of the display signal. Figure 1 As shown, the display pixels 122 in each display area 12 are in the same row. It should be understood that the display area can be divided according to the display requirements of the display device. For example, the display area can be divided so that the display pixels 122 in each display area 12 are in the same column.

[0033] Figure 2 : is a schematic block diagram of an image displayed by a display device according to an embodiment of the present disclosure. Figure 2 As shown, the image may include at least one image area 22, each image area 22 and Figure 1 The display areas 12 shown correspond one to one, such that each display area 12 can be used to display a corresponding image area 22 .

[0034] Figure 3 is a schematic flow chart of a method for processing a display signal of a display device according to an embodiment of the present disclosure. Figure 1 The process of processing the display signal is described by taking the display area 12 in the first row as an example. It should be understood that when processing the display signal of the display area 12 in the first row, the display signals of other display areas can also be processed in parallel.

[0035] like Figure 3 As shown, in block 302, a previous average grayscale value of an image region of a previous frame image corresponding to the display area 12 is determined, and a current average grayscale value of an image region of a current frame image corresponding to the display area 12 is determined. In an embodiment of the present disclosure, the current frame image is an image currently to be displayed by the display device, and the previous frame image is an image that has been displayed before the current frame image.

[0036] The following describes in detail how to determine the previous average grayscale value. First, the sum of the grayscale values ​​of all image pixels in the image area of ​​the previous frame image corresponding to display area 12 is calculated. Then, the ratio of this calculated sum to the number of image pixels in this image area is determined as the previous average grayscale value. Using the same method, for the current average grayscale value, first, the sum of the grayscale values ​​of all image pixels in the image area of ​​the current frame image corresponding to display area 12 is calculated. Then, the ratio of this calculated sum to the number of image pixels in this image area is determined as the current average grayscale value.

[0037] Continue to refer Figure 3 In block 304, the previous average grayscale value is compared with the current average grayscale value. In an embodiment of the present disclosure, the difference between the previous average grayscale value and the current average grayscale value may be determined as the result of the comparison. In this embodiment, the result of the comparison may include the following three cases: the current average grayscale value is greater than the previous average grayscale value, the current average grayscale value is less than the previous average grayscale value, and the current average grayscale value is equal to the previous average grayscale value.

[0038] In block 306, based on the comparison result, a compensation grayscale value is determined for the display area 12. In an embodiment of the present disclosure, if the current average grayscale value is greater than the previous average grayscale value, the compensation grayscale value is determined as the difference between the current average grayscale value and the previous average grayscale value; if the current average grayscale value is less than or equal to the previous average grayscale value, the compensation grayscale value is determined to be zero.

[0039] In box 308, a compensation signal is determined based on the compensated grayscale value. In an embodiment of the present disclosure, the compensation signal can be determined by the following formula: compensation signal = (compensated grayscale value / (grayscale level of the image-1)) × predetermined maximum compensation signal. The grayscale level of the image can be determined according to the number of bits of the image. For example, for an 8-bit image, the grayscale level of the image is 256. In an embodiment of the present disclosure, the maximum compensation signal can be preset. For example, for an 8-bit image, the maximum compensation signal can be preset to 2V. In one example, the grayscale level of the image is 256, the predetermined maximum compensation signal is 2V, and the compensation grayscale value determined in box 306 is 51. The compensation signal can be determined to be 0.4V by the above formula. In this example, when displaying the current frame image, the compensation signal 0.4V can be compensated to the display signal of each display pixel of the display area 12 in the first row. It should be noted that in the present disclosure, the display signal of each display pixel is determined according to the initial grayscale value of the corresponding image pixel of the image to be displayed.

[0040] In the embodiments of the present disclosure, Figure 2 The image region 22 of the image shown may include at least one image pixel 222. Figure 1The display area 12 is shown in a one-to-one correspondence, so each image pixel 222 corresponds one-to-one to a display pixel 122. Image pixel 222 may have at least one color component 224, and a compensation signal corresponding to each color component may be determined according to the above method.

[0041] In one example, the color component 224 includes a red component, a green component, and a blue component, wherein the red component has a first grayscale value, the green component has a second grayscale value, and the blue component has a third grayscale value. Figure 1 The display pixel 122 shown may include a red sub-pixel for displaying a red component, a green sub-pixel for displaying a green component, and a blue sub-pixel for displaying a blue component. The display signal for driving the display pixel 122 includes a first display signal for driving the red sub-pixel to emit light, a second display signal for driving the green sub-pixel to emit light, and a third display signal for driving the blue sub-pixel to emit light.

[0042] In the above example, the previous average grayscale value includes a first previous average grayscale value of the red component, a second previous average grayscale value of the green component, and a third previous average grayscale value of the blue component, and the current average grayscale value includes a first current average grayscale value of the red component, a second current average grayscale value of the green component, and a third current average grayscale value of the blue component.

[0043] Specifically, in block 302, determining the previous average grayscale value includes: determining a first previous average grayscale value of the red component based on the first grayscale value of the red component of each image pixel in the image area of ​​the previous frame image; determining a second previous average grayscale value of the green component based on the second grayscale value of the green component of each image pixel in the image area of ​​the previous frame image; and determining a third previous average grayscale value of the blue component based on the third grayscale value of the blue component of each image pixel in the image area of ​​the previous frame image. Similarly, determining the current average grayscale value includes: determining a first current average grayscale value of the red component based on the first grayscale value of the red component of each image pixel in the image area of ​​the current frame image; determining a second current average grayscale value of the green component based on the second grayscale value of the green component of each image pixel in the image area of ​​the current frame image; and determining a third current average grayscale value of the blue component based on the third grayscale value of the blue component of each image pixel in the image area of ​​the current frame image.

[0044] In box 304, comparing the previous average grayscale value with the current average grayscale value includes: comparing the first previous average grayscale value with the first current average grayscale value of the red component, comparing the second previous average grayscale value with the second current average grayscale value of the green component, and comparing the third previous average grayscale value with the third current average grayscale value of the blue component.

[0045] In the above example, the compensated grayscale value includes a first compensated grayscale value corresponding to the first grayscale value, a second compensated grayscale value corresponding to the second grayscale value, and a third compensated grayscale value corresponding to the third grayscale value.

[0046] Specifically, in box 306, in response to the current average grayscale value being greater than the previous average grayscale value, determining the compensation grayscale value for the display area includes: in response to the first current average grayscale value of the red component being greater than the first previous average grayscale value, determining the absolute value of the difference between the two as the first compensation grayscale value of the red component; in response to the second current average grayscale value of the green component being greater than the second previous average grayscale value, determining the absolute value of the difference between the two as the second compensation grayscale value of the green component; and in response to the third current average grayscale value of the blue component being greater than the third previous average grayscale value, determining the absolute value of the difference between the two as the third compensation grayscale value of the blue component. Similarly, in response to the current average grayscale value being less than or equal to the previous average grayscale value, determining the compensation grayscale value for the display area includes: determining the first compensation grayscale value of the red component to be zero in response to the first current average grayscale value of the red component being less than or equal to the first previous average grayscale value; determining the second compensation grayscale value of the green component to be zero in response to the second current average grayscale value of the green component being less than or equal to the second previous average grayscale value; and determining the third compensation grayscale value of the blue component to be zero in response to the third current average grayscale value of the blue component being less than or equal to the third previous average grayscale value.

[0047] In the above example, the compensation signal includes a first compensation signal for compensating a red sub-pixel, a second compensation signal for compensating a green sub-pixel, and a third compensation signal for compensating a blue sub-pixel.

[0048] Specifically, in block 308, determining the compensation signal includes determining a first compensation signal corresponding to the red component, a second compensation signal corresponding to the green component, and a third compensation signal corresponding to the blue component using the compensation formulas described above, respectively. The first compensation signal is applied to the first display signal of the red sub-pixel in the display area 12, the second compensation signal is applied to the second display signal of the green sub-pixel in the display area 12, and the third compensation signal is applied to the third display signal of the blue sub-pixel.

[0049] As can be seen from the above description, the method according to the embodiments of the present disclosure, by adding the compensation signal to the display signal, can improve the smearing problem caused by the actual drive voltage not reaching the target drive voltage, enhance the display quality, and thus provide users with a better visual experience. In addition, for image pixels whose current average grayscale value is less than or equal to the previous average grayscale value, the display pixels corresponding to these image pixels are not compensated, which saves computing resources.

[0056] Then, the device 40 may determine a compensation signal based on the compensated grayscale value to compensate the display signal of the display pixels of the display area when displaying the current frame image.
