Embedded touch liquid crystal panel and array substrate thereof

Abstract

The invention discloses an embedded touch liquid crystal panel and an array substrate thereof. The array substrate comprises a glass substrate, as well as a thin film transistor, a common electrode layer and a pixel electrode sequentially arranged on the glass substrate, wherein the common electrode layer is divided into multiple long-strip-shaped touch-control driving electrodes insulated to each other, and a plurality of suspension electrodes are arranged inside each touch-control driving electrode; a second insulating layer and a metal wire routing layer are sequentially arranged on the common electrode layer further; the metal wire routing layer comprises a plurality of driving electrode routed wires, a plurality of suspension electrode routed wires and a plurality of touch-control induction electrodes; each driving electrode routed wire is electrically connected with the corresponding touch-control driving electrode through a through hole in the insulating layer; each suspension electrode routed wire is connected to the suspension electrodes arranged in the second direction. According to the embedded touch liquid crystal panel and the array substrate thereof, provided by the invention, the width of the frame of the liquid crystal panel can be reduced, so that the requirement for narrow frames of products can be conveniently met.

Description

Technical field [0001] The invention relates to the technical field of touch control, in particular to an in-cell touch liquid crystal panel and an array substrate thereof. Background technique [0002] As an input medium, touch screen is currently the simplest and most convenient way of human-computer interaction. Therefore, touch screens are increasingly used in various electronic products. Based on different working principles and information transmission media, touch screen products can be divided into four types: infrared touch screens, capacitive touch screens, resistive touch screens and surface acoustic wave touch screens. Among them, capacitive touch screens have long life, high light transmittance and can support multiple Point touch and other advantages have become the current mainstream touch screen technology. [0003] The capacitive touch display device includes a capacitive touch panel. The capacitive touch panel includes a surface capacitive type and a projected ca...
