Abstract

The embodiment of the invention discloses a method for adjusting a drive voltage. The method comprises: a reference brightness value of a light-emitting element in an organic light emitting display device is determined; a light sensor is used for detecting current brightness values of the light-emitting element under different drive voltages; the current brightness values of the light-emitting element are compared with the reference brightness value, and when the current brightness value reaches the reference brightness value, the drive voltage is determined to be a target drive voltage; and a drive voltage inputted to a drive circuit is adjusted to be the target drive voltage. Therefore, the drive voltage is adjusted to enable the current brightness value of the light-emitting element to reach the reference brightness value, so that the aberration is reduced effectively.

Description

technical field [0001] The present invention relates to the technical field of computers, in particular to a driving voltage adjustment method, device and terminal. Background technique [0002] An OLED (Organic Light-Emitting Diode, organic electro-laser display) display screen is a display screen composed of organic light-emitting materials, wherein the organic light-emitting materials can emit colored light when electrified. In view of the advantages of thinness, lightness, large viewing angle and low power consumption, the OLED display screen is widely used in terminals such as smart phones. It should be pointed out that since the light-emitting elements in the OLED display are self-illuminating, the light-emitting process will be accompanied by the consumption of organic light-emitting materials. picture. [0003] In order to reduce the generation of chromatic aberration, a driving circuit is added, and by inputting a driving voltage to the driving circuit, brightness...
