Detection circuit of array substrate and array substrate

Abstract

A detection line layout of an array substrate and array substrate, the detection line layout comprising: a signal pin region (303) including multiple signal pins (304) correspondingly connected to signal lines of the array substrate; a test pin region (301) including multiple test pins (305, 306); a fan-out line region (302), connected between the signal pin region (303) and the test pin region (301), including multiple fan-out lines (307). The signal pins (304) are connected via the fan-out lines (307) to a part of the test pins, and the test pins connected to the signal pins are not immediately adjacent to each other, such that a height of the fan-out line region (302) is reduced.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a detection circuit of an array substrate and the array substrate. Background technique [0002] Generally, in the process of manufacturing the array substrate of the liquid crystal display, millions of thin film transistors are formed on the array substrate of the liquid crystal display as control units by means of epitaxy. However, in the production process of the array substrate, if the quality of some thin film transistors does not meet the preset requirements, then these thin film transistors may not be able to have the function of switch control, so that the curve of bright or dark spots appears on the liquid crystal display, greatly Reduce the quality of the LCD display. Therefore, in the production process of the array substrate, the array substrate must be effectively inspected to ensure the quality of the array substrate. [0003] However, the existing ...

Problems solved by technology

[0003] However, the existing array substrate detection circuit has the defect that the height is too high, which makes the area occupied by the detection circuit too large

Since the detection circuit of the array substrate is mostly arranged on the periphery of the array substrate, the area of ​​the detection circuit is too large and the frame of the liquid crystal display is too large.
