  • Publication number: 20230267866
    Abstract: Provided is a display panel. The display panel includes multiple scanning lines, a gate driver circuit, and a timing controller. The timing controller is configured to: receive multiple data enable signals, generate a gate control signal, and provide the gate control signal for the gate driver circuit. The gate control signal includes a start signal, a first clock signal and a second clock signal. The multiple data enable signals are only within the active cycle. The timing controller is configured to generate a rising edge and a falling edge of the start signal within a time interval formed by a rising edge and a falling edge of a first data enable signal in the Nth frame cycle.
