Description

technical field [0001] The present invention relates to the field of display technology, in particular to a GOA (English: GatedriverOnArray, Chinese full name: integrated gate drive circuit) unit, a GOA circuit, a display drive circuit and a display device. Background technique [0002] Organic light-emitting diode display (English full name: OrganicLight-EmittingDiode, referred to as: OLED) is one of the hot spots in the field of flat panel display research today. It has the advantages of low cost, self-illumination, wide viewing angle and fast response speed. At present, OLEDs have begun to replace traditional liquid crystal displays in display fields such as mobile phones, PDAs (English full name: Personal Digital Assistant, Chinese full name: Pocket Computer), digital cameras, etc. [0003] The GOA circuit design for OLED has always been a core issue of continuous research by those skilled in the art. Generally, a gate drive signal and a pixel electrode reset signal ne...
