A gate drive circuit with ultra-narrow frame

Abstract

The invention discloses a grid driving circuit with an ultra-narrow frame, belonging to the field of electronic technology. The grid driving circuit comprises a multi-stage driving unit, the driving unit comprises an Nth pixel module, a switching module and an N+1th pixel module, N is a positive integer, and the switching module is respectively electrically connected with the Nth pixel module andthe N+1th pixel module. The grid driving circuit disclosed by the invention has the advantages that one gate line is used for driving two rows of pixels by virtue of special pixel design, so that halfof gate routing is reduced; meanwhile, double height can be used for designing a GOA unit, the width of the GOA unit is indirectly reduced, narrow frame design is realized, and the scheme also can save half of gate routing space for a non-GOA product; meanwhile, actual pixels are controlled by two TFT switches, leakage current is relatively small when the TFTs are turned off, voltage holding ratio is high, and lower power consumption can be realized by using relatively low frequency drive.

Description

【Technical field】 [0001] The invention relates to the field of electronic circuits, in particular to a gate drive circuit with an ultra-narrow frame. 【Background technique】 [0002] With the popularization of mobile phones and other products, people's requirements for product appearance are increasing day by day, and the concepts of full screen and borderless / narrow border screen are also deeply rooted in the hearts of the people. However, low-power products usually have more grid traces, and it is difficult to achieve narrow borders. Wait for the request. Often because the space occupied by the gate traces hinders the capacity increase of the capacitor, etc., it is necessary to design a drive circuit with fewer gate traces. At the same time, the existing circuit design fails to combine the narrow frame and low power consumption drive together, so that the drive circuit and integrated circuit design cannot meet the requirements of low power consumption and narrow frame. 【...

[0002] With the popularization of mobile phones and other products, people's requirements for product appearance are increasing day by day, and the concepts of full screen and borderless / narrow border screen are also deeply rooted in the hearts of the people. However, low-power products usually have more grid traces, and it is difficult to achieve narrow borders. Waiting for request

It is often because the space occupied by the gate traces hinders the capacity increase of the capacitor, etc., so it is necessary to design a drive circuit with fewer gate traces

At the same time, the existing circuit design fails to combine the narrow frame and low power consumption drive together, so that the drive circuit and integrated circuit design cannot meet the requirements of low power consumption and narrow frame.
