Abstract

The invention discloses a grid electrode driving circuit unit, a grid electrode driving circuit and a display device. The grid electrode driving circuit unit comprises a first clock signal control module, an input signal control module, a third clock signal control module and a fourth clock signal control module, wherein the first clock signal control module comprises a driving unit and a clock feed-through inhabiting unit, the driving unit transfers a first clock signal to an output port after being switched on, the clock feed-through inhabiting unit couples the control end of the driving unit to a signal output interface under the control of the first clock signal, the input signal control module provides the driving voltage for the driving unit under the control of an input pulse signal, the third clock signal control module provides the shutdown voltage for the driving unit under the control of a third clock signal, the third clock signal lags two phases behind the first clock signal, the fourth clock signal control module pulls down the voltage of the signal output interface under the control of a fourth clock signal, and the fourth clock signal is one phase ahead the first clock signal. The invention has the advantages of simple design, small power consumption and high stability.

Description

technical field [0001] The invention relates to a display device, in particular to a gate drive circuit of the display device. Background technique [0002] The amorphous silicon TFT process has the characteristics of low processing temperature, uniform device performance, low cost, and is suitable for large-area display. Therefore, the amorphous silicon TFT LCD process has become the mainstream of modern flat panel display technology. [0003] Gate drive circuit is an important part of amorphous silicon TFT LCD. In order to further improve the performance of amorphous silicon TFT LCD and reduce its cost, in recent years, the research of integrated amorphous silicon TFT gate drive circuit has received extensive attention. At present, the gate driving method adopted by most flat panel displays is to connect the peripheral IC chip to the display panel by pressing and sealing. Compared with this conventional method, the method of integrating the amorphous silicon TFT gate driv...

Problems solved by technology

However, the gate drive circuit of this two-phase clock has obvious shortcomings: the power consumption of the circuit is large, the stability is poor, and the number of devices leads to complex circuits and large layout areas.

These deficiencies limit the application of the integrated gate drive circuit of the two-phase clock in the fields of low power consumption, high performance and high resolution display.
