Method and system for eliminating afterimage defect of static-state image display area

Abstract

The invention discloses a method and system for eliminating an afterimage defect of a static-state image display area, and is applied to a self-luminous display apparatus. The static-state image display area comprises at least two sub pixels of the same type yet with different grayscale values. The method comprises: obtaining the first grayscale value of a sub pixel of a reference type corresponding to the static-state image display area, wherein the reference type is any one from RGB types, and the first grayscale value is the maximum grayscale value in the grayscale values of all the sub pixels of the reference type; according to the first grayscale value, determining a second grayscale value, the second grayscale value being greater than or equal to the first grayscale value; and driving a reference sub pixel to work continuously for corresponding reference compensation time, and closing a sub pixel whose grayscale value is equal to the second grayscale value, wherein the reference sub pixel is any one sub pixel of the reference type, whose grayscale value is smaller than the second grayscale value, and the reference compensation time is the continuous work time of the reference sub pixel. By using the technical scheme provided by the embodiments of the invention, once an image of the self-luminous display apparatus generates the afterimage defect problem, the problem can be rapidly eliminated.

Description

technical field [0001] The invention relates to the field of image display, in particular to a method and a system for eliminating residual image defects in a static image display area. Background technique [0002] At present, OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) displays made of organic materials are very widely used because of their fast response speed and wide viewing angle, and they can be rolled, folded, or used as a part of wearable computers. application. [0003] In an OLED display, for sub-pixels of the same type, if there is a brightness difference between each sub-pixel, during the display process, due to the different brightness of each sub-pixel, the magnitude of the driving current required by each sub-pixel is also different, that is The higher the brightness of the sub-pixel, the greater the driving current it needs to provide, so the heating temperature of each sub-pixel is not the same, and as the working time increases, each ...
