Sensor, dual-mode touch module and dual-mode touch electronic device

Abstract

The invention discloses a sensor, a dual-mode touch module and a dual-mode touch electronic device. The sensor comprises a first direction lead set and a second direction lead set formed by a plurality of U-shaped first direction leads and second direction leads in a combined arrangement mode. The first direction lead set and the second direction lead set are mutually crossed to form a capacitance coupling touch antenna array; the first connecting end of the opening parts of the first direction leads and the second direction leads is connected with an external control component, the second connecting end of the opening parts is connected in series with a mode switching electronic switch, and the second connecting end is connected to the external control component through the mode switching electronic switch; and the control end of the mode switching electronic switch is connected with the external control component. The sensor realizes dual touch modes of capacitance coupling and electromagnetic induction by mode switching based on the same antenna array, and has simple structure, high reliability and low cost; and when the sensor is combined on a display screen of electronic equipment, the sensor meets the requirements of users on two flexible touch inputs of electromagnetic pen and finger touch.

Description

technical field [0001] The invention relates to a sensor, a dual-mode touch module and a dual-mode 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. [0003] Among them, the resistive touch control mainly realizes the sensing of the touch point 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. [0004] 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 touch mode, that is, the capaci...

AI Technical Summary

Problems solved by technology

However, each array structure needs to be connected to its own processing circuit, which makes the structure of the entire touch control product complex, bulky, and high in manufacturing cost

And during the use of touch products, there will be mutual interference between the capacitive touch mode and the electromagnetic induction touch mode

Therefore, none of the above-mentioned touch products can better meet the needs of users.
