Abstract

The embodiment of the application provides a pixel circuit, an array substrate and a display pane. The pixel circuit comprises a reset unit, a data voltage write-in unit, a storage unit, a driving unit, a light-emitting control unit and a light-emitting unit; various units are correspondingly connected with a reference power end, a scanning end, a reset end, an emitting control end, a data end, afirst power end, a second power end, a first control point, a second control point and a third control point; the light-emitting of the light-emitting unit is controlled through the on-off of the control circuit. The pixel circuit provided by the embodiment of the application can effectively improve the short residual image problem, the display effect is improved, and the use experience of a useris enhanced.

Description

technical field [0001] The present application relates to the field of display technology, in particular, the present application relates to a pixel circuit, an array substrate and a display panel. Background technique [0002] AMOLED (Active-matrix organic light-emitting diode, active matrix organic light-emitting diode or active matrix organic light-emitting diode) display technology, its display brightness is proportional to the light-emitting current of OLED (Organic Light-Emitting Diode, organic light-emitting diode) Proportional, when the OLED device is lit, the pixel circuit provides the OLED with a light emitting current, thereby forming a path from the anode power supply end to the cathode power supply end, and realizing the light emission of the OLED. [0003] However, due to the hysteresis effect of the drive transistor, when the OLED display panel switches to a 48-grayscale screen after lighting the black-and-white screen for a period of time, an afterimage will ...
