The disclosure relates to a compensation module, a logic gate circuit, a gate drive circuit and a display device, the compensation module includes a first switch unit and a second switch unit, the first switch includes a first control terminal and a second control terminal, The first control terminal is connected to the input signal terminal, the first switch unit is turned on in response to the input signal to transmit the first power supply signal to the second power supply terminal, and the second control terminal is connected to the compensation node, The first switch unit is turned on in response to the compensation signal to transmit the first power signal to the second power terminal; the second switch unit is turned on in response to the first control signal to transmit the first power signal to the second power supply terminal; the signal output terminal is connected to the first terminal of the first switch unit; the first on-state resistance of the first switch unit is smaller than the second on-state resistance. It solves the drift caused by the threshold voltage in long-term use, and improves the stability of the logic gate circuit.
Description
technical field [0001] The present disclosure relates to the field of display technology, in particular, to a compensation module, a logic gate circuit, a gate drive circuit and a display device. Background technique [0002] A large number of gate circuits are often used in the drive circuit of the display panel, for example, NOT gates or NOR gates and NAND gate circuits are widely used in the drive circuits of the display panel. [0003] At present, more transistors are often used in the gate circuit in the driving circuit, and the gate of the transistor is connected to the switch voltage signal, which will cause threshold voltage drift, thereby reducing the stability of the gate circuit. For example, for the gate circuit of an N-type transistor, when the high level is applied to the gate of the transistor, the threshold voltage drift caused by the high level is greater than the drift caused by the low level, and the on-state current of the transistor will gradually decrea...
