Description

Method for adjusting color of display screen and mobile terminal

technical field

The invention relates to the field of mobile communication, in particular to a method for adjusting the color of a display screen and a mobile terminal.

Background technique

At present, since the organic light-emitting diode (OLED) display is self-illuminating and does not require a backlight, its visibility and brightness are relatively high, and because the OLED display has low voltage requirements and high power-saving efficiency, further Coupled with the advantages of fast response, light weight, thin thickness, simple structure, and low cost, many mobile terminal displays use OLED displays.

Existing mobile terminals all can be provided with status bar or virtual key at the top or bottom of the display screen, and the background color of this status bar or virtual key is generally a single color (usually black) that cannot be adjusted. Since the display process of the OLED display is a process of continuous consumption of luminescent materials, if the status bar or virtual button displays a still image for a long time, it is easy to leave afterimages, which is the so-called "burn-in" phenomenon. The main reason is It is because the status bar or the virtual button usually displays a dark color, so the consumption of luminescent material here is relatively small, but the luminescent material in other places of the display that often display bright colors (such as white) is consumed too quickly, causing OLED The color deviation problem of the display screen.
