Problems solved by technology

In slight cases, this afterimage will gradually fade away, but if the still image is played for a long time or accumulated for a long time, it will cause permanent damage and is irreversible
At present, in order to prevent permanent screen damage of OLED TVs, it is necessary to avoid allowing them to display static images for a long time

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] like figure 1 As shown, a method for avoiding OLED burn-in phenomenon includes: comparing each pixel of the Nth frame of the current display output with the newly input N+Kth frame of the picture, and when the pixel values ​​are the same, the pixel outputs a black pixel value , otherwise, output the pixel value of the N+Kth frame and update the display output.

[0020] In this embodiment, specifically include:

[0021] Step S1: input the Nth frame picture and store it in the DDR memory;

[0022] Step S2: Outputting and displaying the Nth frame;

[0023] Step S3: No operation is performed in the middle K-1 frame, and the N+Kth frame is input;

[0024] Step S4: compare the N+Kth frame picture with the Nth frame picture in the DDR memory, compare pixel by pixel, when the pixel value is the same, the pixel outputs a black pixel value, otherwise o...

Abstract

The invention discloses a method for avoiding an OLED burning phenomenon. The method comprises each pixel of an Nth frame of display output at present is compared with that of a newly input (N+K)th frame, when the pixel values are the same, the pixel outputs a black pixel value, and otherwise, the pixel value of the input (N+K)th frame is output, and display output is updated. The method is simpleand easy to realize, and OLED mura can be eliminated effectively.

Description

technical field [0001] The invention relates to the technical field of OLED display, in particular to a method for avoiding OLED burning phenomenon. Background technique [0002] OLED has the phenomenon of afterimage on the screen. When the static picture is too long, the OLED material will deteriorate due to excessive polarization, resulting in image retention and cannot be recovered. The image is still for a long time, and there is a strong contrast between light and dark in the picture. After the picture is switched, some shadows of the original bright part will still remain in the picture. In slight cases, this afterimage will gradually fade away, but if the still image is played for a long time or accumulated for a long time, it will cause permanent damage and is irreversible. At present, in order to prevent permanent screen damage to OLED TVs, it is necessary to avoid allowing them to display static images for a long time. Contents of the invention [0003] Aiming ...
