Problems solved by technology

However, the capacitive touch mode, that is, the capacitively coupled touch mode, requires a densely arranged array structure, which requires an array capable of outputting or inputting current signals, which leads to an increase in the number of I / O interfaces of the control circuit or chip. , so that the reaction speed of touch products is reduced, which leads to the inability to better recognize the position information of touch points
If the touch screen of an existing large-sized touch product adopts a capacitive touch mode, the touch product needs to be equipped with a relatively high processor operation to obtain the position information of the touch point, which makes the cost of the touch product very high. high and unresponsive

Abstract

Disclosed are a metal mesh dual-touch sensor, a touch module and an electronic touch device, wherein the metal mesh dual-touch sensor comprises a metal mesh dual-touch sensor array. The metal mesh dual-touch sensor array comprises a first-direction metal mesh group and a second-direction metal mesh group insulated from each other, wherein the first-direction metal mesh group comprises two or more parallel first-direction metal meshes, and the second-direction metal mesh group comprises two or more parallel second-direction metal meshes. The metal mesh of the metal mesh dual-touch sensor is an ultrafine metal mesh not directly distinguishable to the human eye, and the touch module can be directly disposed in any position on a display screen surface of an electronic device. The convenient, simple and low-cost structural design of the present invention facilitates the popularization and implementation of touch devices. Additionally, since the metal mesh dual-touch sensor is made of a material with low impedance and a high signal-to-noise ratio, the popularization and implementation of touch devices with larger form factors can be realized.

Description

Technical field [0001] The invention relates to touch technology, in particular to a metal mesh double touch sensor, a touch module and a touch electronic device. Background technique [0002] At present, touch products mainly include finger touch products and pen-write touch products. The touch modes of these touch products are basically capacitive touch mode and resistive touch mode. Among them, the resistive touch mode mainly implements the sensing of touch points by arranging two non-contact ITO conductive films on the touch area of ​​the display screen. The main disadvantages are: the upper and lower ITO conductive films are prone to contact failures, which makes the resistive touch response insensitive, and the resolution to handwriting or pen writing is low. [0003] Compared with the resistive touch mode, the sensitivity of touch products in the capacitive touch mode has a certain improvement. However, capacitive touch mode, that is, capacitive coupled touch mode requires...
