Abstract

The invention provides a display and a pixel compensation method thereof. The pixel compensation method comprises that the driving current of each target pixel is detected within starting time of the display; the voltage compensation value of the target pixel is determined according to the present driving voltage, the driving current and a preset threshold voltage of the target pixel; and voltage compensation is carried out according to the voltage compensation value of the target pixel. Thus, voltage compensation is carried out on an aged pixel driving circuit, driving current output by the aged pixel driving circuit can be compensated, the defects including reduced brightness and ghost caused by aging can be solved, and normal use of users is not influenced.

Description

technical field [0001] The invention relates to the technical field of pixel compensation of a display, in particular to a pixel compensation method of a display and a display. Background technique [0002] At present, with the development of display technology, there are more and more types of displays. Among them, Organic Light-Emitting Diode (OLED) display is a self-luminous display. The light-emitting principle of OLED is similar to that of ordinary inorganic light-emitting diodes (Light- Emitting Diode (LED for short) devices have a similar light-emitting principle, that is, a very thin organic light-emitting material is deposited between two electrodes, and a direct current is applied to the organic light-emitting material to make it emit light; because of its fast response speed, wide viewing angle, and organic The material can be rolled, folded, or used as a part of wearable devices, so it has a very wide range of applications in special fields such as portable produ...
