Abstract

The invention provides an integrated electromagnetic and capacitance induction input device which comprises a base plate, a control element and at least one signal processing element arranged on the base plate, wherein the base plate comprises an electromagnetic induction loop and a capacitance induction loop. In the invention, the capacitance induction touch control element is arranged below the electromagnetic induction loop and the electromagnetic induction loop is arranged above the capacitance induction touch control loop through a wiring way of matching loops by arranging the electromagnetic induction loop and the capacitance induction touch control loop in different layers of the base plate in a staggered wiring manner. While the take-up area of the electromagnetic induction loop is wired at the periphery of the capacitance induction loop, even if the electromagnetic induction loop take-up and wiring are dense, the lower capacitance induction is not disturbed to cause poor induction sensitivity.

Description

technical field [0001] The invention relates to an input device, in particular to an integrated electromagnetic and capacitance induction multi-point input device. Background technique [0002] Depending on the type of contact object, such as the user's finger, digital pen or electromagnetic pen (stylus), and the method of determining the position of the contact point, such as the position or distance close to the contact object during operation, touch or input The technology is divided into touch technologies such as capacitive-type, capacitive-type, electromagnetic-type and infrared-type. [0003] Capacitive touch input technology is that the screen module includes a sensing layer that can store charges. The sensors located around the touch screen apply an electric field to the surface of the touch screen and form a capacitor. For a passive touch source such as a user's finger or a conductive device, when the touch source touches the surface of the touch screen, a curren...
