Problems solved by technology

In the process of image generation, transmission and transformation, due to the influence of many factors, the image quality will always decline, so the image processing technology
The early method of changing the image quality is mainly to improve the clarity of the image, that is, to improve the contrast of the image, which is achieved by trimming the grayscale of a given image. However, some existing technologies improve the image while reducing the image quality. brightness

Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] see figure 1 , figure 1 It is a schematic flowchart of an embodiment of the method for optimizing the highest brightness of OLED Mura compensation in the present invention. It should be noted that if there are substantially the same results, the method of the present invention does not figure 1 The flow sequence shown is limited. Such as figure 1 As shown, the method includes the following steps:

[0022] S101: Input the brightness matrix of the OLED panel.

[0023] S102: Divide the brightness matrix of the OLED panel into partitions.

[0024] Wherein, partition refers to dividing the image to be processed horizontally and vertically. In general, too many partitions will affect the calculation speed; too few partitions will make the calculation result inaccurate and affect the local brightness. Optionally, the image can be divided into ...

Abstract

The invention discloses a maximum luminance optimization method and a device in OLED Mura compensation. The maximum luminance optimization method comprises the steps of inputting OLED panel luminance matrix; partitioning the OLED panel luminance matrix; collecting luminance values of sampling points in each zone; making calculation every two sampling points to draw new luminance value; calculating target luminance based on location of the sampling point and new luminance value to draw target luminance matrix; outputting target luminance matrix of the OLED panel. In the above way, the maximum luminance optimization method and device in OLED Mura compensation can somewhat enhance luminance and reduce Mura phenomenon.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for optimizing the maximum brightness of OLED Mura compensation. Background technique [0002] With the development of displays, image quality is increasingly valued by consumers, so various image algorithms that can improve display effects have been widely used. In the process of image generation, transmission and transformation, due to the influence of many factors, the image quality will always be reduced, so image processing technology has been produced. The early method of changing the image quality is mainly to improve the clarity of the image, that is, to improve the contrast of the image, which is achieved by trimming the grayscale of a given image. However, some existing technologies improve the image while reducing the image quality. brightness. Contents of the invention [0003] The technical problem mainly solved by the present inventi...
