Abstract

The invention discloses a shift register unit, a gate driving circuit, a display device, and a driving method. The shift register unit comprises: a first input sub-circuit, configured to receive a display input signal from a display input terminal and input a display output control signal to a first node in a display period of one frame according to the display input signal; a second input sub-circuit, configured to receive a random input signal in a display period of a frame and input a blanking output control signal to the first node in a blanking period of a frame according to the random input signal; and an output sub-circuit, configured to output a composite output signal via an output terminal under the control of the first node.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a shift register unit, a gate drive circuit including the shift register unit, and a driving method applied to the shift register unit. Background technique [0002] In the field of display, especially OLED display, the gate drive circuit is currently integrated in the GATE IC. The area of ​​the chip in IC design is the main factor affecting the cost of the chip. How to effectively reduce the chip area is a key consideration for technology developers. [0003] At present, the OLED gate drive circuit is usually composed of three sub-circuits, namely, the detection unit (sense unit), the display unit (scan unit) and the connection unit (OR gate circuit or Hiz circuit) that outputs the composite pulse of the two. The structure is very complicated and cannot meet the requirements of high-resolution narrow bezels. Contents of the invention [0004] In order to solve t...
