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 an electromagnetic induction array, wherein the electromagnetic induction array comprises multiple first direction leads in combined arrangement and multiple second direction leads in combined arrangement; each of first direction leads and second direction leads comprise a first lead, a second lead and a connecting line; each connecting line is provided with a mode control switch for disconnecting the connecting line, and the control end of the mode control switch is connected with an external control component; and when the external control component controls the mode control switch to disconnect the connecting line, the corresponding first leads and second leads in the first direction lead group and the second direction lead group form a capacitive coupling touch array so as to enable the sensor to work in a capacitive coupling touch mode. The sensor can recognize signals of finger touch and electromagnetic pen touch by virtue of the same array, thus simplifying the structure of the sensor and lowering the manufacturing cost.

Description

technical field [0001] The invention relates to touch technology, in particular to a sensor with capacitive and inductive touch capabilities, a dual-mode touch module and a dual-mode touch electronic device. Background technique [0002] Capacitive touch technology is mainly used in products that are directly touched by fingers, such as mobile phones, computers, video playback terminals, etc. Inductive touch technology is mainly used in products that use pens that emit electromagnetic signals to write, such as electronic whiteboards, children's learning machines, etc. [0003] The capacitive touch sensor mainly adopts a densely arranged array structure. When a finger touches the array structure, it detects the high-speed current or voltage scanning signal conducted by the finger to realize the positioning of the touch point. The advantage of the capacitive touch sensor is that the sensitivity is higher than that of the resistive film touch sensor, and it can be directly con...

AI Technical Summary

Problems solved by technology

Its advantage is that it is suitable for people to write with a pen; its disadvantage is that the electromagnetic induction array can only receive the signal sent by the electromagnetic pen, and cannot detect the signal touched by human fingers

However, simple stacked touch products have complex structures, large volumes, and high manufacturing costs

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

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