Abstract

The invention relates to an input device compatible with capacitance positioning and electromagnet positioning and an input method of the input device. The input device comprises an input induction unit, an oscillating unit, a data processing unit and a control unit, wherein the oscillating unit provides a first oscillating signal suitable for electromagnetic testing and capacitance testing for the input induction unit. The input induction unit comprises a first group of conductors extended along a first direction and a second group of conductors extended along a second direction, and is used for inducting input of an electromagnetic pen and inputting and outputting an electromagnetic signal and / or a touch control signal through a touch control manner. The data processing unit is used for determining the input positions according to an induction signal. When the electromagnetic signal and the touch control signal are output by the input induction unit, and the data processing unit is controlled by the control unit based on the electromagnetic signal or the touch control signal, and input positions can be ensured. Due to the adoption of the input device and the input method disclosed by the input device, so that signal interferences due to misoperation can be effectively avoided, input precision can be improved and input experience of uses can be improved.

Description

technical field [0001] The invention relates to an input device and an input method. Specifically, the present invention relates to an input device and an input method compatible with capacitive positioning and electromagnetic positioning. Background technique [0002] In recent years, due to the advent of Apple's iphone, capacitive touch technology has become a research hotspot. In fact, the capacitive screen is a coordinate identification device. Compared with other coordinate positioning technologies such as resistive, optical, and acoustic, the capacitive screen is widely used in such as because of its high positioning accuracy, durability, and multi-touch support. In the field of electronic equipment such as mobile phones and computers. The capacitive screen can be touched only by fingers, and can recognize various gesture operations, which cannot be replaced by other positioning technologies, and has a strong sense of fashion. There are many implementations of capac...
