Problems solved by technology

At present, due to the demand for high resolution and high display effect, the resolution of the display panel is getting higher and higher. When processing multiple pictures, the time to obtain the original display data in the display panel is getting longer and longer, which increases a lot of test time. This in turn reduces the compensation efficiency

Embodiment Construction

[0037] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0038] The following will combine figure 1 Describe the acquisition process of mura compensation data. figure 1 The system shown in includes a display panel 101 , an image acquisition device 102 and a terminal 103 . Wherein, the display panel 101 is a display panel that needs to be compensated, and is used for displaying a detection picture in a preset gray scale, and the detection picture includes sub-pixels of at least two colors among three colors of R, G, and B. The image acquisition device 102 acquires an image of the detection screen, and sends the acquired image t...

Abstract

The invention relates to a mura compensation method and system of a display panel, computer equipment and a storage medium. The method comprises the steps that of lighting a display panel, wherein thedisplay panel comprises lighted feature sub-pixels of at least two colors; collecting brightness data of the display panel under a preset gray scale; extracting current brightness data of the characteristic sub-pixels of the at least two colors according to the brightness data; and determining the brightness compensation value of the display panel according to the current brightness data of the characteristic sub-pixels of the at least two colors. By adopting the method, the picture shooting frequency can be reduced, so that the shooting time is saved and the compensation efficiency is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a mura compensation method, device, computer equipment and storage medium for a display panel. Background technique [0002] With the development of display technology, AMOLED (Active-matrix organic light-emitting diode, active-matrix organic light-emitting diode) display panels are widely used due to their high contrast, ultra-thin, flexible and many other advantages. The AMOLED display panel usually has the problem of uneven brightness of the display screen due to reasons such as technology and materials, which is also called mura. In order to improve the display effect of the display panel, the display panel needs to be compensated, and compensation techniques are usually divided into internal compensation and external compensation. Among them, the external compensation can be divided into optical extraction type and electrical extraction type according to differen...
