Problems solved by technology

[0003] However, during the use of the OLED display, due to the rapid attenuation of the blue pixels, the screen will appear yellowish.
Especially for folding display screens, since the secondary screen folded to the back of the main screen is used for less time, the screen attenuation degrees of the main screen and secondary screen are different. Therefore, when the main screen and secondary screen are unfolded and displayed together, the The degree of yellowishness is different, so it is easy to produce differences in display effects that users can perceive

Abstract

Embodiments of the present application provide a display screen aging compensation method, a circuit system, and an electronic device, which relate to the field of display technology and are used for performing aging compensation on a display screen to reduce display differences. The aging compensation method of the display screen includes: firstly, acquiring display data of each display area. Wherein, the display data includes the use time t of the display area, the maximum value of the grayscale Lev_max of each primary color before the display data is acquired, and the average value Lev of the grayscale of each primary color within the use time t. Next, the attenuation ratio of each primary color in the display area is obtained according to the display data. Finally, aging compensation is performed on each display area according to the attenuation ratio of each primary color in each display area.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display screen aging compensation method, circuit system, and electronic equipment. Background technique [0002] With the rapid progress of display technology, semiconductor element technology, which is the core of the display device, has also been greatly improved. For existing display devices, Organic Light Emitting Diode (OLED) is a current-type light-emitting device, because of its characteristics of self-luminescence, fast response, wide viewing angle and the ability to be fabricated on flexible substrates. And it is increasingly being used in the field of high-performance display. [0003] However, during the use of the OLED display, due to the rapid attenuation of the blue pixels, the screen will appear yellowish. Especially for folding display screens, since the secondary screen folded to the back of the main screen is used for less time, the screen attenu...
