Abstract
A display panel with image sticking elimination circuit is provided. The image sticking elimination circuit can be applied in a display unit comprising a plurality of pixel units driven by a gate driving circuit and a data driving circuit. The gate driving circuit is driven by a first voltage and a second voltage. The first voltage turns on the pixel units for receiving data signals and the second voltage turns off the pixel units for preventing the pixel units from receiving data signals. A switch is coupled between a data line driven by the data driving circuit and an ESD circuit. The image sticking elimination circuit is charged by the first voltage and the charged power is output to turn on the switch and the pixel units when abnormal power shut down occurs.
