Problems solved by technology

Although the method of changing the area and arrangement of sub-pixels can solve the problem of screen burn-in to a certain extent, it is accompanied by the emergence of some new problems, such as image color fringing and aliasing problems caused by sharing sub-pixels, and blurred images caused by too small pixel pitch problem, the resolution drop problem caused by the reduction of the total number of sub-pixels, etc.

Embodiment 1

[0022] The present invention provides such Figure 1-2 A kind of anti-burn screen OLED RGB pixel display method, comprises the steps:

[0023] A method for displaying an anti-burn-in OLED RGB pixel, comprising the steps of:

[0024] S1: The detection and judgment module 8 monitors the input display signal, and when it is detected that the input display signal in a certain area has not changed for a long time, it is judged to enter the protection display mode in this case;

[0025] S2: After entering the protection display mode, each sub-pixel will be dynamically displayed according to the set rule to prevent each sub-pixel from being in a certain fixed brightness display state for a long time, so as to solve the aging of OLED pixels caused by long-term lighting, burn-in problem;

[0026] S3: The detection and judgment module 8 keeps monitoring the input display signal, and returns to the normal display mode when the signal in this area changes;

[0027] S4: In the normal di...

Embodiment 2

[0049] image 3 Shown is a schematic diagram of a RGB pixel display method of the burn-in-resistant screen OLED RGB pixel proposed by the present invention, including: red sub-pixel A 1, red sub-pixel B 2, green sub-pixel 41, blue sub-pixel E 5, The blue sub-sub-pixel F6 and the substrate 7 . Compared with traditional RGB pixels, in this embodiment, each R and B sub-pixel is divided into two sub-pixels according to the area, and each sub-pixel can independently control the switch and brightness. The OLED used here has the characteristics of high brightness, which can ensure that the brightness of each sub-pixel meets the requirement.

Abstract

The invention discloses an anti-burn-in OLED RGB pixel display method comprising the following steps: S1, a detection and judgment module monitors an input display signal, and when it is monitored that the display signal input in a certain area for a long time does not change, it is judged that a protection display mode is entered under the condition; s2, after entering a protection display mode, performing dynamic display on each secondary sub-pixel according to a set rule to prevent each secondary sub-pixel from being in a certain fixed brightness display state for a long time, thereby solving the problems of OLED pixel aging and burn-in caused by long-term lightening; s3, the detection and judgment module keeps monitoring the input display signal, and when the signal of the area changes, the normal display mode is returned; and S4, in a normal display mode, each secondary sub-pixel is displayed according to the conventional brightness. The advantages of high resolution, high definition, good edge effect and the like of a standard RGB pixel display panel are reserved; the problem of burn-in of an OLED panel using RGB pixel arrangement is solved.

Description

technical field [0001] The invention belongs to the technical field of OLED displays, and in particular relates to a method for displaying OLED RGB pixels with an anti-burning screen. Background technique [0002] With the development of display technology, OLED (Organic Light-Emitting Diode) display devices have gradually matured and entered the public eye, showing the potential to rival LCD (Liquid Crystal Display), the mainstream display device in the market. OLED devices have excellent performance in terms of brightness, color saturation, thinness, viewing angle, and response speed, but they have a fatal weakness of screen burn-in. Screen burn-in refers to the phenomenon of image retention after a certain area of ​​the screen displays a fixed pattern for a long time. The cause is that a small range of light-emitting points ages too quickly after being turned on for a long time, especially in the RGB pixel arrangement. [0003] In view of the driving current and life pro...
