Control switch of driving circuit, array substrate and display panel

Abstract

The invention discloses a control switch of a driving circuit, an array substrate and a display panel, the control switch comprises a thin film transistor, the driving circuit further comprises a source electrode lead, the thin film transistor comprises a source electrode, a drain electrode and a grid electrode, the source electrode comprises a plurality of source electrode branches arranged in parallel, and the drain electrode comprises a plurality of drain electrode branches which are arranged in parallel; the source electrode branch directly connected with the source electrode lead is a first source electrode branch, the drain electrode branch adjacent to the first source electrode branch is provided with a groove, the opening of the groove faces the source electrode lead, and the extension line of the source electrode lead is overlapped with the groove. The groove is formed in the drain electrode branch adjacent to the first source electrode branch, but the distance from the source electrode lead to the drain electrode branch is increased, if the problem of non-uniform etching occurs, the source electrode lead cannot intersect with the drain electrode, short circuit of the source electrode and the drain electrode cannot be caused, and therefore, the design of the groove is beneficial to improving the production yield of products.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a control switch of a driving circuit, an array substrate and a display panel. Background technique [0002] Currently, display technologies are widely used in displaying televisions, mobile phones, and public information, and display panels for displaying images are also various, and can display rich and colorful images. More and more display panels, such as Thin Film Transistor-Liquid Crystal Display (TFT-LCD for short), Organic Light Emitting Diode (OLED for short), etc., require the use of array substrates. Gate Driver on Array (GOA for short) technology integrates the array substrate row drive circuit on the array substrate in the display panel to form a scan drive for the display panel, thereby reducing product cost in terms of material cost and manufacturing process. [0003] Usually, when making a GOA circuit, the source, drain and source lead in the thin ...

Problems solved by technology

[0003]Usually, when making a GOA circuit, the source, drain and source lead in the thin film transistor are set on the same layer and etched simultaneously, but when the etching process The problem of uneven etching is prone to occur; and as the integration of GOA circuits becomes higher and higher, the distance between the source and drain becomes smaller and smaller, so when the etching is uneven, it will cause the source lead to be connected with the drain at the same time. The source and drain are connected so that the source and drain are shorted
