Abstract

The invention provides a GOA (Gate Drive ON Array) device and a gate drive circuit. The gate drive circuit comprises at least one clock signal source; a constant voltage low level source; and the GOAdevice. The GOA device comprises at least two GOA units. Each GOA unit comprises a pull-up control module, at least one first pull-up module, at least one second pull-up module, a pull-down module, apull-down maintaining module, at least one bootstrap capacitor and at least one second bootstrap capacitor. According to the GOA device and the gate drive circuit, at least two pull-up modules and atleast two bootstrap capacitors are set in each GOA unit; each pull-up module corresponds to a clock signal source; and through utilization of the pull-up control modules, the pull-down modules and thepull-down maintaining modules, two adjacent lines of pixel units share a gate drive circuit, layout of GOA circuits in a frame area is reduced, and design of an ultra narrow frame is realized.

Description

technical field [0001] The present application relates to the display field, in particular to a GOA device and a gate drive circuit. Background technique [0002] The Gate Drive ON Array (GOA) technology is to integrate the scanning line driving circuit on the array substrate of the liquid crystal panel, so as to reduce the product cost in terms of material cost and manufacturing process. [0003] With the development of technology in the display industry, users have higher and higher requirements for the appearance design of the display panel, such as the design of a narrow frame. A large number of GOA traces are provided in the frame area of ​​the display panel, so that the frame area cannot be further reduced. [0004] Therefore, this application proposes the following technical solutions based on this technical problem. Contents of the invention [0005] The present application provides a GOA device and a gate driving circuit to realize the design of a narrow frame o...
