Problems solved by technology

In order not to affect the pixel aperture ratio, the metal connection line is generally arranged above the data line of the touch panel, so there will be a resistive capacitive load (RC Loading) between the metal connection line and the data line, and the load will affect The accuracy of the touch signal transmitted by the metal connection leads to a decrease in touch accuracy

Abstract

The present disclosure relates to an array substrate of embedded touch panels. The array substrate includes a touch electrode arranged in an active area of the touch panel in a matrix, a touch sensing chip arranged outside the active area of the touch panel, a plurality of metal connecting lines arranged on a different layer with the touch electrode. The metal connecting lines connect to the touch electrode via at least one through hole, and the metal connecting line and a data line of the touch panel are insulated from each other and are overlapped. The touch electrode connects to the touch sensing chip via the metal connecting line, wherein a switch circuit is arranged between the metal connecting line and the data line. The switch circuit connects the metal connecting line and the data line in a touch phase, and the switch circuit disconnects the metal connecting line and the data line in a display phase.

Description

technical field [0001] The present invention relates to a touch panel, in particular to an in-cell touch panel and an array substrate thereof. Background technique [0002] Liquid crystal display (Liquid Crystal Display, LCD) is the most widely used flat panel display at present, and has gradually become a variety of devices such as mobile phones, personal digital assistants (PDAs), digital cameras, desktop computers or laptop computers A display with a high-resolution color screen used in electronic equipment. [0003] With the development and progress of liquid crystal display technology, people put forward higher requirements for LCD display quality, appearance design, human-machine interface, etc. hotspots. [0004] Touch technology has developed rapidly in recent years, and various touch panels have been put into mass production. For the existing touch panel, according to the position of the touch sensor (Touch Sensor), it can be divided into the type where the touch...
