Problems solved by technology

However, irradiation from the TFT array panel side may result in insufficient light to harden the encapsulant, especially when the width of the signal lines or transistors in the gate drive circuit is greater than 100 μm
As a result, the two panels may be susceptible to moisture ingress through the insufficiently hardened encapsulant, causing corrosion of the gate drive circuitry

Abstract

The gate driving circuit of the thin film transistor array panel is formed on the same plane as the display area of ​​the transistor array panel. The gate driving circuit includes a driving circuit and a signal line with a hole. Therefore, even if the light is irradiated from the thin film transistor array panel side, a sufficient amount of light can reach the phototypesetting sealant at least partially overlapping the gate driving circuit. The thin film transistor array panel and the opposing panel are assembled together air-tightly and moisture-tightly. As a result, the gate drive current can prevent corrosion caused by externally introduced moisture. It can also reduce gate drive circuit failures.

Description

technical field [0001] The present invention relates to display device technology, and more particularly, relates to the design and application of a thin film transistor array panel and a display device including such a thin film transistor array panel. Background technique [0002] Generally, a display device includes a display panel, a gate driving circuit and a data driving circuit. The display panel includes a thin film transistor array panel having gate lines, data lines, pixel electrodes, and thin film transistors; an opposite panel having one or more common electrodes; and a liquid crystal layer provided between the two panels. The two panels are aligned and sealed with sealant. The gate driving circuit and data driving circuit are usually provided on a printed circuit board, or as an integrated circuit connected to the display panel. [0003] Recently, in order to minimize device size and increase efficiency, gate driving circuits have been directly formed on thin ...
