Abstract

The application discloses a display panel, a pixel circuit and a driving method thereof. The pixel circuit includes a driving chip, and a plurality of pixel circuit units and a plurality of detectingcircuit units connected to the driving chip; the pixel circuit unit includes a first switching transistor and an electroluminescent element; each detecting circuit unit includes a selection circuit, and the selection circuit includes a second switching transistor and a connection switching transistor; a first access end of the second switching transistor is connected to an anode of the electroluminescent element in the pixel circuit unit through the connection switching transistor and the pixel circuit unit; the control end of the second switching transistor is connected to a first timing signal end; the second access end of the second switching transistor is connected to the driving chip; and at least two adjacent detecting circuit units are connected in a second direction through connection terminals, and the two adjacent detecting circuit units are connected to the same pin of the driving chip through the connection terminals. The application can facilitate the anode potential detection of a high pixel density display panel, and can improve the display effect of the display panel.

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...
