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, thereby increasing the I / O interface 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 net electromagnetic touch sensor, a touch module and an electronic touch device. The metal net electromagnetic touch sensor comprises an electromagnetic induction array, the electromagnetic induction array comprises a first-direction metal net set and a second-direction metal net set which are insulated mutually, the first-direction metal net set is composed of two or more first-direction metal nets which are mutually parallel, and the second-direction metal net set is composed of two or more second-direction metal nets which are mutually parallel. Extremely fine metal nets which cannot be directly distinguished with the human eyes are adopted as the metal nets forming the electromagnetic touch sensor, the touch module is directly arranged at any position of the surface of a display screen of an electronic device with the display screen, can be arranged at the position between display screen glass and back light and also can be arranged on the back face of the back light of the display screen, and the structural design is convenient and simple, low in cost and convenient to apply and popularize; due to the fact that the electromagnetic touch sensor is made of the metal nets, the resistance is low, the signal to noise ratio is very high, and the electromagnetic touch sensor can be applied and popularized to touch products with the larger size.

Description

technical field [0001] The invention relates to touch technology, in particular to a metal mesh electromagnetic 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. The touch mode substrates of these touch products are 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 capa...
