Benefits of technology

This technology improves the performance of semiconductor devices used for data communication between different components on printed wiring boards (PWBs). By reducing temperature fluctuations during operation, this helps maintain stable power supply levels at higher speeds while also increasing device's reliability. Additionally, it simplifies the overall structure of the PWD system without adding extra parts or requiring more space than necessary. Overall, these improvements improve the efficiency and quality of electronic systems utilizing semiconducers such as computers.

Problems solved by technology

This patented technical solution described by this patents relates to improving the performance and lifespan of a semiconductor device called an LC filter or liquid crystal display (AML). These devices use Thinner Gate Liquid Crystal Display(TFT), where there are fewer lines between components compared to previous designs. Additionally, these circuits have lower leakage currents than older technologies like CMOS image sensor arrays, reducing their impact on signal quality during operation. By optimizing certain parameters within specific areas of the chip structure, we aimed at achieving higher efficiency and better functionality over existing products while minimizing costs associated with production processes.

Abstract

The embodiment of the invention discloses a GIA (Gate-driver In Array) circuit and a display device, belonging to the display driving technical field. The GIA circuit comprises a pre-charge module, a transmission signal generation module, a stabilizing module and an output module. When the transmission signal outputted by an (n-3)th level of GIA unit circuit becomes a high level form a low level, and the grid scanning signal outputted by the (n-3)th level of GIA unit circuit also becomes a high level form a low level, the pre-charge module charges a control node through an output terminal; when a clock signal becomes a high level form a low level, the transmission signal generation module performs charge pump on the control node, rising the potential of the control node; when the control node is pulled down to a low level, the stabilizing module pulls down and stabilizes the control node and the output terminal; when the control node is a high level, the low level of the clock signal is applied to a grid scanning signal output terminal. According to the invention, the circuit output capability and stability are improved.
