Abstract

The embodiment of the invention provides a shifting register unit, a driving method thereof, a grid driving circuit and a display device, relating to the technical field of display, and solving the problem that the wiring space of a non-display region is relatively small because multiple different signals ends of an OLED pixel circuit respectively correspond to one grid driving circuit. The shifting register unit comprises at least two of a first output sub-circuit, a second output sub-circuit and a third output sub-circuit, wherein the first output sub-circuit is used for outputting voltage of a signal output end to a reset signal output end; the second output sub-circuit is used for outputting the voltage of the signal output end to a gating signal output end; and the third output sub-circuit is used for outputting voltage of a second voltage end to a lighting control signal output end or outputting the voltage of a first voltage end to the lighting control signal output end. The shifting register unit is used for supplying at least two of a reset signal, a gating signal and a lighting control signal to the OLED pixel circuit.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a shift register unit, a driving method thereof, a gate driving circuit, and a display device. Background technique [0002] With the rapid progress of display technology, semiconductor element technology, which is the core of the display device, has also been greatly improved. For existing display devices, Organic Light Emitting Diode (OLED) is a current-type light-emitting device, because of its characteristics of self-luminescence, fast response, wide viewing angle and the ability to be fabricated on flexible substrates. And it is increasingly being used in the field of high-performance display. [0003] A pixel circuit is arranged in a sub-pixel of an OLED display device, and the pixel circuit has a plurality of different signal terminals. In the prior art, for each signal terminal of the pixel circuit, a driving circuit connected to the signal terminal needs to be...
