Embodiment 1
[0051]This embodiment provides a new structure of the shift register module. By adding a type field effect transistor at the output end and controlling the switch of the field effect transistor through the enable signal, it can not only output normal high and low levels, but also output high-impedance state , so that the output signal produces three states, which can effectively prevent the gate drive circuit from affecting the display circuit part due to parasitic effects in a specific state.
[0052] Such as figure 1 Shown is the structural block diagram of the shift register module in this embodiment. The shift register module includes an input subcircuit 1, a shift register subcircuit 2, an output subcircuit 3 and an output buffer subcircuit 4 arranged in cascade in sequence, wherein:
[0053] The input sub-circuit 1 is connected with the first input signal terminal, the second input signal terminal, the first control signal terminal and the second control signal terminal...
Embodiment 2
[0073] This embodiment provides a gate driving circuit, including the shift register module in Embodiment 1.
[0074] In this gate drive circuit, multiple shift register modules are connected in cascade, such as Figure 4 As shown, the input signals of each stage of shift register module include the first input signal STV_N-1 and the second input signal STV_N+1, and STV_N-1 is from the shift register sub-circuit 2 in the shift register module of the upper stage The output signal STV_N, STV_N+1 is the output signal STV_N from the shift register sub-circuit 2 in the shift register module of the next stage, which are respectively used as the two input signals of the shift register module of the present stage, and the shift register module of the present stage The output signal of the bit register sub-circuit 2 is located between the first input signal and the second input signal in time sequence.
[0075] Since the gate drive circuit adopts the above-mentioned shift register mod...
Embodiment 3
[0077] This embodiment provides a display device, which includes the gate driving circuit in Embodiment 2.
[0078] The display device can be: desktop computer, tablet computer, notebook computer, mobile phone, PDA, GPS, vehicle display, projection display, video camera, digital camera, electronic watch, calculator, electronic instrument, instrument, liquid crystal panel, electronic paper, TV Computers, monitors, digital photo frames, navigators and other products or components with display functions can be applied to multiple fields such as public display and virtual display.
