Array substrate and manufacturing method and display device thereof

Abstract

The embodiment of the invention provides an array substrate and a manufacturing method and a display device thereof and relates to the technical field of display. A conductive adhesive can be prevented from inwards permeating into a peripheral lead of the array substrate through the cutting breakage position of a colored film substrate after the array substrate and the colored film substrate are aligned, a peripheral lead signal can be prevented from being subjected to crosstalk, and the problem of poor display of the display device caused by the inwards permeating conductive adhesive is solved. The array substrate comprises the peripheral lead and a grounding signal end for being connection with a transparent conductive layer on the colored film substrate through the conductive adhesive and further comprises a retaining wall structure located between the peripheral lead and the grounding signal end and used for preventing the conductive adhesive from permeating towards the peripheral lead. The manufacturing method is used for manufacturing the array substrate and the display device including the array substrate.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a preparation method thereof, and a display device. Background technique [0002] Small-sized LCD products (Liquid Crystal Display, liquid crystal display devices) applied to mobile phones, tablet computers, etc. are mainly obtained through the following methods: [0003] The large-size color film motherboard and the array motherboard are boxed to form a display motherboard, and the display motherboard is cut to form a Q-panel for standard testing including several small-size LCD products; where "Q" means " quality (quality)". The surface of Q-panel's color filter is coated with a layer of transparent conductive layer, whose function is to transfer the electrostatic charge accumulated on the color filter. Afterwards, the Q-panel is cut again to form multiple single panels (single panels), that is, multiple small-sized LCD products. Among them, in o...

Problems solved by technology

[0005] In view of this, in order to solve the problems of the prior art, the embodiments of the present invention provide an array substrate and its preparation method, and a display device, which can prevent the conductive adhesive from being damaged from the cutting of the color filter substrate after the array substrate and the color filter substrate are boxed together. Infiltrate into the peripheral leads of the array substrate, avoid the crosstalk of peripheral lead signals, and reduce the problem of poor display of the display device caused by the infiltration of conductive glue
