Abstract

An embodiment of the invention discloses a light emitting control method of a light emitting element, a light emitting control device and a mobile terminal, wherein the light emitting method comprises the steps of when light emitting through a current light emitting element is required, determining whether the current light emitting element is in a preset target area; and if the light emitting element is in the target area, making the current light emitting element alternatively emit light or do not emit light. Through the light emitting control method of the light emitting element, the light emitting control device and the mobile terminal, light emitting of the light emitting element can be controlled through a preset duty ratio, thereby slowing aging of the light emitting element.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a method and device for controlling light emission of a light emitting element and a mobile terminal. Background technique [0002] At present, Organic Light-Emitting Diode (OLED) is an emerging application technology of flat-panel displays. Due to its self-luminous characteristics, no need for backlight source, energy saving, large viewing angle and other advantages, it has been used in mobile phones. , digital cameras, tablet PCs and televisions are widely used in terminals. [0003] However, since OLED is self-illuminating, its light emitting process is a process of continuous consumption of OLED materials. Therefore, as time goes by, the OLED material will age, resulting in a gradual decrease in its luminosity, chromatic aberration, etc., and a poorer display effect. Contents of the invention [0004] Embodiments of the present invention provide a light...
