DISPLAY PANEL

摘要

A display panel includes a substrate, a plurality of pixels, a plurality of scan lines, a pull-down control circuit, and a gate driving circuit. The pixels are disposed on a display area of the substrate. The scan lines are disposed on the substrate and respectively coupled to the corresponding pixels. The pull-down control circuit is disposed on a peripheral area of the substrate, receives a plurality of clock signals, and has a plurality of pull-down units to provide a plurality of pull-down signals. The gate driving circuit is disposed on the peripheral area and has a plurality of shift registers. The shift registers are coupled to the scan lines to provide a plurality of gate driving signals and pull down the gate driving signals in sequence according to the pull-down signals. The pull-down control circuit and the gate driving circuit are arranged along a side of the display area.
