goa unit, array substrate, display device and manufacturing method

Abstract

The invention discloses a GOA unit, an array substrate and a display device. The area of a GOA circuit is reduced, and the narrow bezel design is achieved. The GOA unit comprises a capacitor structure, and the capacitor structure at least comprises a first capacitor and a second capacitor which are connected in parallel. The first capacitor comprises a first pole plate and a second pole plate which are arranged oppositely, and the second capacitor comprises the first pole plate and a third pole plate which are arranged oppositely. The second pole plate and the third pole plate are distributed on the two sides of the first pole plate, and at least one part of the orthographic projection of the second pole plate on the first pole plate and at least one part of the orthographic projection of the third pole plate on the first pole plate are overlapped. According to the GOA unit, the array substrate and the display device, the area of the GOA circuit is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a GOA unit, an array substrate, a display device and a manufacturing method. Background technique [0002] At present, for thin film transistor array substrate displays (TFT-LCD), the peripheral chips tend to be integrated on the glass substrate, that is, the peripheral chips are omitted, and the driving circuit is directly fabricated on the glass substrate. In the current technology, the gate drive signal is output to the gate on the glass through the chip on the external flexible circuit board, and the flexible circuit board is connected together by thermal compression after the glass substrate process is completed. The gate drive integration technology (GOA technology) does not require a flexible circuit board, but directly builds the drive circuit on the glass substrate, which not only saves cost, but also reduces the size of the frame. [0003] As narrow bezel display devi...

AI Technical Summary

Problems solved by technology

In order to realize the above-mentioned capacitor and ensure the design specifications of the capacitor, the entire GOA circuit structure requires a relatively large facing area between the first metal layer and the second metal layer, so the entire first metal layer and the second metal layer need to occupy a large area. Large area, do not use narrow frame design
