Abstract

The embodiment of the invention discloses a gray scale setting method and a user terminal. The method comprises steps of determining a target pixel point, wherein the gray scale values a red sub pixel point, a green sub pixel point and a blue sub pixel point of the target pixel point are the same; judging whether the gray scale values of the sub pixel points of the target pixel point are larger than a first preset value; and if yes, setting the gray scale values of the sub pixel points of the target pixel point to be second preset values which are smaller than the first preset value. In this way, by applying method and the user terminal, reduction of attenuation speed of organic materials of a display screen is facilitated.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a gray scale setting method and a user terminal. Background technique [0002] Organic light-emitting diodes (Organic Light-Emitting Diode, OLED) have been widely used in display screens of terminals such as mobile phones, tablet computers, and televisions due to their characteristics of self-illumination and power saving. The grayscale values ​​of OLED three primary colors (yellow / green / blue) are divided into 256 levels from low to high. The 255th level corresponds to the highest grayscale value, and the 0th level corresponds to the smallest grayscale value. During the light emitting process of the OLED, the organic material of the OLED will be continuously attenuated (that is, consumed). If the luminescent material is in the highest grayscale condition for a long time, the consumption rate of the OLED luminescent material will be accelerated. However, it has...
