Problems solved by technology

[0005] However, the above-mentioned technology will be difficult to achieve the required specifications as the current product specifications have higher and higher resolution requirements and narrower frame requirements, so that the area of ​​the final gate driver will still be limited. The size of the circuit structure of the gate driver itself

Abstract

The present invention provides a display panel and a gate driver thereof. The gate driver comprises a plurality of cascading driving stages which are used for sequentially outputting a plurality of gate driving signals, and each driving stage includes a mobile deposit unit, a control unit and a buffer unit. The mobile deposit unit is used for generating a shifting signal. The control unit receives a power source signal, used for performing single-pass reversal processing on the shifting signal, and used for outputting the shifting signal after phase reversal at a normal operating state and outputting a high level voltage signal according the power source signal at an off-position state. The buffer unit is used for reception and buffer output of the shifting signal after the phase reversal or the high level voltage signal, so as to serve as one of the gate driving signals.

Description

technical field [0001] The present invention relates to a display panel, in particular to a gate driver in the display panel. Background technique [0002] Recently, products of various liquid crystal displays have been considerably popularized. In order to effectively increase the viewing area of ​​the liquid crystal display, display panel technologies suitable for narrow borders have been continuously proposed. For example, taking the gate driver circuit as an example, both the double-sided single-drive shift register circuit architecture and the shared (co-used) shift register architecture can be applied to narrow-frame display panels. [0003] In terms of the double-sided single-drive shift register circuit architecture, the shift register circuits in the gate driver are respectively arranged on both sides outside the pixel area of ​​the display panel, and the shift register circuit on one side is responsible for transmitting odd-numbered levels of gate drive. signal, ...
