Abstract

A display panel and a pixel circuit thereof are provided. The display panel includes a plurality of gate lines, a plurality of data lines, and a plurality of pixel circuits. Each of the pixel circuits is coupled to corresponding gate line and data line. Each of the pixel circuits includes a first gate line and a pull-low switch. The first gate line is coupled to a control terminal of a driving transistor, and provides a first gate signal to drive the driving transistor during a driving time period. The pull-low switch pulls low the first gate signal to a reference low voltage according to a second gate signal on a second gate line when the driving time period finishes.
