Abstract

The invention discloses a display panel, a pixel circuit and a driving method thereof. Specifically, the pixel circuit includes a driving chip, and a plurality of pixel circuit units and a plurality of detection circuit units that are connected to the driving chip, when second switching tubes in the detection circuit units are in an on-state and first switching tubes in coupling connection in thepixel circuit units are also in an on-state, the driving chip detects the anode potentials of electroluminescent elements in the pixel circuit units corresponding to the first switching tubes in an on-state, wherein the plurality of detection circuit units fall into several groups, each group includes at least two detection circuit units, the detection circuit units in each group are connected byconnecting terminals, and are correspondingly connected to a same pin of the driving chip through the connecting terminals. The pixel circuit provided by the invention can be convenient for the anodepotential detection of a high pixel density display panel, can improves the display panel display effect, and improves the detection efficiency.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a pixel circuit and a driving method thereof. Background technique [0002] AMOLED (Active-matrix organic light-emitting diode, active-matrix organic light-emitting diode or active-matrix organic light-emitting diode) displays are widely used in mobile phones and TVs due to their advantages such as wide viewing angle and low power consumption. [0003] However, as time goes by, the efficiency of OLED (organic light-emitting diode, organic light-emitting diode) will also decline rapidly, which will lead to a gradual decrease in the brightness of the screen body. It affects the display effect and the service life of the display panel. Contents of the invention [0004] The main problem to be solved by the present application is to provide a display panel, a pixel circuit and a driving method thereof, which can improve the display effect of the display panel and...
