Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] The present invention includes a surface acoustic wave touch sensing module, an electromagnetic induction module, a control module, and a display device. The surface acoustic wave touch sensing module and the electromagnetic induction module are fixed through the display device, and the surface acoustic wave touch sensing module and the electromagnetic induction module pass the collected information through the control module. Sent to the external operating system after processing. The external operating system may be an information processing device such as a computer.

[0022] As a first embodiment of the present invention, such as figure 1 As shown, the surface acoustic wave touch sensing module is stacked above the display device, and the electromagnetic induction module is sequentially stacked above the surface acoustic wave touch sensing module....

Abstract

The invention relates to a multi-mode coordinate, a pressure input device and a pressure input method, and belongs to the field of display device information input. The pressure input device comprisesa surface acoustic wave touch induction module, an electromagnetic induction module, a control module and a display device; the surface acoustic wave touch induction module and the electromagnetic induction module are fixed through the display device, and send acquired information which is processed by the control module to an external operation system. When writing is performed on the device, and an input mode is detected by the control module; when the input mode is electromagnetic pen input, the control module controls the electromagnetic induction module to detect signals input by an electromagnetic pen; and when the input mode is touch input, the control module controls the surface acoustic wave touch induction module to detect signals input by touch. The device has multiple modes such as the electromagnetic pen input, the touch input and the like, provides convenience for users, and contributes to the improvement of input efficiency.

Description

technical field [0001] The invention belongs to the field of display device information input, and relates to a coordinate input device, in particular to a coordinate and pressure input device which can adopt multiple input modes such as touch input and pen input. Background technique [0002] The display device information input device is mainly touch type or electromagnetic type. Using touch technology, users only need to lightly touch the icons or text on the computer display screen with their fingers to operate the host computer, thus making the human-computer interaction more straightforward. However, the touch screen can only be used in places where the resolution is not high, and cannot meet the needs of high resolution such as painting. The development of electromagnetic handwriting technology has been very mature so far. It can directly display the trajectory drawn by the input pen on the display screen. The accuracy is higher than that of the touch screen, and it ...
