Abstract
A display panel and a pixel circuit thereof are provided. A pulse width signal generator turns on a charge sharing switch during a light-emitting period, and performs charge sharing with a control end of a positive feedback switch of a positive feedback circuit, so as to control the positive feedback switch to provide a positive feedback voltage to the pulse width signal generator to increase a voltage at an output end of the pulse width signal generator and thus to accelerate a rising speed of a voltage for controlling a driving current generator to provide a driving current.
