Problems solved by technology

With the increase of use time, the proportion of RGB three-color light has changed relative to the original state, and the proportion of blue light is getting smaller and smaller, resulting in a yellowish screen display; when the color cast is serious, the screen cannot be used normally , which in turn leads to a shortened lifespan of the OLED
At present, there is no effective way to increase the effective use time of OLED screens, except to improve the aging speed of different color illuminants of OLEDs as much as possible.

Abstract

The invention discloses a screen color adjustment method applied to an electronic device, wherein the electronic device comprises an organic light emitting diode (OLED) screen. The method includes the following steps that: the accumulated use time of the OLED screen is obtained; the display color adjustment parameter of the OLED screen is determined according to the accumulated use time; and display data outputted to the OLED screen are adjusted according to the display color adjustment parameter. The invention also discloses a screen color adjustment device. With the screen color adjustment method and device provided by the technical schemes of the invention adopted, the problem of color deviation of the OLED screen caused by inconsistency of aging speed of different color light emitting bodies can be solved, and the effective use time of the screen is prolonged.

Description

technical field [0001] The invention relates to the display field, in particular to a screen color adjustment method and device. Background technique [0002] Organic Light Emitting Diode (OLED, Organic Light Emitting Diode) has many advantages such as high color, wide viewing angle, high contrast, high response speed, light and thin, low power consumption, etc., and has been applied in the display screens of high-end mobile phones and tablet computers. According to the principle of color light generation, color OLED can be divided into three types: red, green and blue (RGB) sub-pixel independent light emission, color filter, and color conversion. Among them, RGB sub-pixel independent light-emitting OLED, because of its color performance With the characteristics of strong capability and high luminous efficiency, it is the most widely used technology mode at present. [0003] Aging phenomenon occurs during the use of OLED, that is, the luminous intensity decreases slowly wit...
