Abstract

The invention relates to the technical field of display, in particular to a shift register unit, a shift register circuit and a display device. The shift register unit comprises a detection input module, a display input module, an inverter module, a pull-down module, a reset module and a first output module. In the working process of the shift register unit, the display input module and the detection input module share the inverter module, the pull-down module, the reset module and the first output module, so that the circuit structure of the shift register unit is greatly simplified, the areaof the shift register circuit is greatly reduced, and the requirements of high resolution and narrow frame can be met.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to a shift register unit, a shift register circuit, and a display device. Background technique [0002] In the field of display, especially in the field of OLED display, the shift register unit is integrated in the driving IC. During the design process of the driver IC, how to effectively reduce the chip area of ​​the driver IC so as to reduce the cost of the driver IC has become one of the important topics for the research and development personnel. [0003] At present, the shift register unit is generally composed of three sub-circuits, wherein the three sub-circuits are respectively a detection sub-circuit, a display sub-circuit, and a connection unit that outputs the detection sub-circuit and the coincident pulse of the display narcissism circuit. [0004] Obviously, the circuit structure of the above-mentioned shift register unit is very complicated, and the chip are...
