A kind of shift register, gate driving circuit, display panel and driving method

Abstract

The invention discloses a shift register, a gate driving circuit, a display panel and a driving method. The shift register comprises an input control unit, which is used for controlling to input a first input signal and a second input signal; a register unit, which is used for outputting a first output signal and a second output signal according to the first input signal and the second input signal; a first shift output unit, which is used for outputting a light-emitting control signal according to the first output signal and the second output signal; and a second shift output unit, which is used for outputting a scanning signal according to the first output signal and the second output signal. The shift register is simple in structure, can output the light-emitting control signal and the scanning signal simultaneously with small number of thin film transistors, has stable node voltage, adopts small number of signal lines, is low in production cost and is convenient for narrow frame design.

Description

technical field [0001] The present invention relates to the technical field of display devices, and more specifically, to a shift register, a gate driving circuit, a display panel and a driving method. Background technique [0002] With the continuous development of science and technology, more and more display devices are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and has become an indispensable and important display device for people. tool. [0003] The OLED display panel is a display panel widely used in display devices. When the OLED display panel is driven for display, it needs to be driven by scanning through a light emission control signal and a scanning signal. The OLED display panel is scanned and driven by a gate drive circuit, and the gate drive circuit includes a plurality of cascaded shift registers to sequentially scan the pixel units of the OLED display panel. [0004] Existing shift register...

AI Technical Summary

Problems solved by technology

[0004] Existing shift registers can only output light-emitting control signals or scanning signals alone, which leads to the need to use two shift registers for driving and scanning for the same pixel row, and one shift register is used to output light-emitting control signals for the pixel row , another shift register is used to output the scan signal for the pixel row

In this way, the circuit structure of the gate drive circuit is complicated, which is not convenient for the narrow frame design of the OLED display panel.
