Abstract
A display panel includes multiple gate lines and a gate driver. The gate driver includes multiple shift registers. Each of the shift registers includes a pull-up circuit, a driving circuit, and a pull-down circuit. The pull-up circuit charges a first node in the shift register. The driving circuit is coupled to the first node, and outputs, according to a voltage signal of the first node, a driving pulse signal to a corresponding gate line. The pull-down circuit is coupled to the driving circuit, and discharges one of the gate lines according to the voltage signal of the first node. The shift register includes a first shift register provided on a first side and a second shift register provided on a second side. The pull-down circuit in the first shift register discharges a gate line corresponding to the second shift register according to the voltage signal of the first node.
