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

The invention relates to a metal mesh double-touch sensor, a touch module and an electronic touch device. The metal mesh double-touch sensor comprises a metal mesh double-touch sensing array, wherein the metal mesh double-touch sensing array comprises a first-direction metal mesh group and a second-direction metal mesh group which are insulated from each other; the first-direction metal mesh group comprises more than two parallel first-direction metal meshes; the second-direction metal mesh group comprises more than two parallel second-direction metal meshes. The metal meshes of the metal mesh double-touch sensor are ultra-fine metal meshes that cannot be distinguished directly by human eyes, and the touch module is directly arranged in any position on the surface of a display screen of an electronic device provided with the display screen; the structural design is convenient and simple, the cost is low, and popularization and application are facilitated; the metal mesh double-touch sensor can be popularized and applied to touch products with larger size due to the fact that the metal mesh double-touch sensor is made of the metal mesh material and has low impedance and very high signal to noise ratio.

Description

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