Abstract

The invention provides a light-emitting shift register, a light-emitting control method, a driving circuit and a display device, aiming to simplify circuit structures and improve circuit stability. The light-emitting shift register comprises a first processing module, a second processing module and an output module. The first processing module is used for controlling signals of a first node according to signals of an input signal terminal, a first clock signal terminal and a second clock signal terminal. The second processing module comprises a first transistor and a second transistor. The first transistor is a dual-grid transistor. The first end of the second transistor is connected with a pulse signal terminal electrically. The second end of the second transistor is connected with a second node electrically. The output module is used for controlling signals of an output signal terminal according to signals of a first level signal terminal, a second level signal terminal, the first node and the second node.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a light-emitting shift register, a light-emitting control method, a driving circuit and a display device. 【Background technique】 [0002] Generally speaking, a display device includes a plurality of sub-pixels inside a display panel and a light-emitting driving circuit for driving these sub-pixels to emit light. The light-emitting driving circuit generally consists of a plurality of cascaded light-emitting shift registers. In the prior art, each light-emitting shift register needs to be provided with two output terminals, one output terminal is connected to the light-emitting control line located in the display area, and the other output terminal is connected to the input signal terminal of the next-level light-emitting shift register , resulting in a complex structure of the light-emitting shift register and poor circuit stability. 【Content of invention】 [0003] In view o...
