Problems solved by technology

[0006] Since the gate of the first transistor is connected to the first control point, when the voltage of the first control point and the voltage of the output signal terminal are equal to the first voltage, the voltage between the gate of the first transistor and the output signal terminal The difference is zero, and in a high temperature environment, abnormal display will be caused due to large leakage current, which will reduce the display effect
However, if the process makes the characteristic curve drift to the right, it is more difficult

Description

technical field [0001] The invention relates to the display field, in particular to a GOA circuit, a driving method and a display device. Background technique [0002] Liquid crystal displays are widely used in electronic products such as televisions, mobile phones, and monitors. They are composed of a matrix of pixels in both horizontal and vertical directions. When displaying, the gate driving circuit outputs driving signals to scan each pixel of the liquid crystal display row by row, and the data driving circuit inputs data signals to the pixels of each row of scanning to make the liquid crystal display display. [0003] Among them, there is currently a gate drive circuit called GOA (GateOnArray) circuit. GOA refers to a shift register device that realizes Gate (gate) drive on glass (glass) by semiconductor technology. The GOA circuit includes a drive module and a first A transistor, the driving module is connected to the first control point, the input signal terminal, t...
