Dual-mode input device

Abstract

The invention discloses a dual-mode input device, which comprises a control module used for processing input information, a display module used for displaying the input information, an electromagneticinduction module for acquiring electromagnetic pen input information, and a capacitive touch module for acquiring touch information. The control module processes the input information acquired by theelectromagnetic induction module and the capacitive touch module and transmits the input information to peripheral equipment, such as a computer, an embedded system and the like. The peripheral equipment drives the display module to display the input information from the control module to display equipment of the display module. The dual-mode input device integrates electromagnetic touch technology with capacitive touch technology, can be operated in a mode of touching with a hand, also can be operated by writing, drawing and the like with an electromagnetic pen, so the device has compact structure and convenient use.

Description

technical field [0001] The invention belongs to the field of display device information input, and relates to a dual-mode input device, in particular to an input device capable of realizing hand touch input and electromagnetic pen writing input. Background technique [0002] At present, electromagnetic touch technology is favored by the market due to its high positioning accuracy, the ability to obtain pen tilt angle and pressure information, and not affect the quality of screen display when used in the display field. It is widely used in handwriting computers, drawing screens, and drawing tablets. , tablet, mobile phone, e-book and other equipment. Electromagnetic touch devices used in the display field generally use a matching electromagnetic pen to write and input pressure information and coordinate information on the display screen. However, this input mode must use an electromagnetic pen. Once the electromagnetic pen is lost, the electromagnetic touch function will not...

Problems solved by technology

However, this input mode must use an electromagnetic pen. Once the electromagnetic pen is lost, the electromagnetic touch function will not be realized. Moreover, in the display field, the touch operation with the electromagnetic pen is not as flexible and convenient as the finger touch operation.

The capacitive touch screen uses finger touch input, which is convenient and flexible. It can also realize multi-touch, which can make up for the defects of the electromagnetic touch input mode. However, the capacitive touch screen cannot be accurately positioned and cannot directly reflect the pressure of the finger touch.

Therefore, capacitive touch screens cannot be used alone in display fields that require painting functions.
