[0035] see image 3 , which is a schematic diagram of the structure of a single-stage GOA unit in a preferred embodiment of the GOA circuit of the present invention. The number of TFTs in the GOA unit is six, and the TFT can be designed with a double-gate TFT, and the TFT top gate can be used to connect the GOA circuit. node, the bottom gate can be used to connect an external voltage source. The present invention uses a group of CK clock signals (three clock signals in total, CK1, CK2, CK3) for driving, the first clock signal CK1, the second clock signal CK2 and the third clock signal CK3 have the same waveform, and the duty cycle is three One, and the phases differ by one third of the cycle in turn, the GOA units at all levels input the corresponding two clock signals according to the driving sequence, image 3 The single-stage GOA unit shown takes the first clock signal CK1 and the second clock signal CK2 as examples for drawing. Two of the third clock signals CK3 are used...
