Abstract

The invention discloses a dual-touch device with piezoelectric touch and electromagnetic touch and a touch method of the device, belonging to the field of digital processing. The dual-touch device comprises a touch panel, an electromagnetic induction panel arranged under the touch panel, a piezoelectric touch module attached on the surface of the touch panel, and a control module electrically connected with each of the electromagnetic induction board and the piezoelectric touch module. In the device, if the electromagnetic induction signal and the piezoelectric signal are simultaneously generated, the signals with a high priority level are processed according to the pre-determined priority levels, so as to obtain the touch information; if only the piezoelectric signal is generated, the piezoelectric signal is processed, so as to obtain the touch information; and if only the electromagnetic induction signal is generated, the electromagnetic induction signal is processed, so as to obtain the touch information. According to the device and the method disclosed by the invention, production cost can be reduced, the touch accuracy can be increased, the anti-interference performance is improved and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a dual touch device and method with piezoelectric touch and electromagnetic touch. Background technique [0002] Currently, touch screens are mainly classified into resistive, capacitive, electromagnetic and piezoelectric types. The price of resistive screen is very low, but it has the disadvantages of low precision, poor stability, and easy to produce scratches; capacitive screen has high precision, but the price and cost are high, and can only be operated by fingers or conductive media; electromagnetic screen High resolution, sensitive reflection, good effect in handwriting recognition, drawing, etc., but because it uses magnetic field changes to determine the touch position, it can only be operated with a pen with electromagnetic induction function; piezoelectric touch screen price It is lower than the capacitive touch screen, and its anti-interference is stronger, and it can t...
