    Abstract: A shift register, a gate driving circuit, a display panel and a driving method. The shift register includes: an input circuit, an output circuit, a pull-up-node pull-down circuit, a first control circuit, a second control circuit and an output pull-down circuit. The first control circuit is configured to write a fourth clock signal into a first pull-down node and write a first power voltage into a second pull-down node responsive to a first control signal, and to write the first power voltage into the first pull-down node responsive to a voltage of a pull-up node. The second control circuit is configured to write the fourth clock signal into the second pull-down node and write the first power voltage into the first pull-down node responsive to a second control signal, and to write the first power voltage into the second pull-down node responsive to the voltage of the pull-up node.

    IPC: G06F1/16

    Abstract: A display panel includes: a base substrate including a display region and a fan-out region, and the fan-out region is located between the display region and a chip; a plurality of data wires/touch wires located in the fan-out region for respectively electrically connecting a plurality of data lines/touch signal lines with the chip. A portion of the plurality of data wires is located in a first conductive layer while a rest portion thereof is located in the second conductive layer. A portion of the plurality of touch wires is located in at least one of the first conductive layer and the second conductive layer while a rest portion thereof is located in the third conductive layer. A pitch between any two adjacent wires in the first/second/third conductive layer is a first/second/third wire pitch, respectively. The first wire pitch and the second wire pitch are smaller than the third wire pitch.
