Problems solved by technology

However, in practical applications, when the user clicks on the casing of the electronic device, or when an external force is transmitted to the casing, the vibration of the casing will also cause deformation of the display screen. In this case, if the deformation generated by the display screen is Sensed by the deformation sensor, it will output a signal and cause misoperation of electronic information equipment

Embodiment Construction

[0036] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0037] The coordinate input device provided by the present invention includes: a solid-state panel, a control module, a deformation sensor electrically connected to the control module, and a force-sensitive sensor. The force-sensitive sensor is electrically connected to the control module, and is judged by the signal output by the control module After the force sensitive sensor is triggered, the trigger position on the solid-state panel is obtained according to the signal output by the deformation sensor. In the following specific embodiments, the solid-state panel is a display screen.

[0038] The force-sensitive sensor receives the pressure on the surface of the solid-s...

Abstract

The invention discloses an anti-interference coordinate input device and method, belonging to the technical field of electronic digital data processing. The device provided by the invention comprises a solid state panel, a control module, a deformation sensor which is electrically connected with the control module and a force sensor, wherein the force sensor is electrically connected with the control module; and when the control module outputs a signal through the force sensor and judges that the force sensor is triggered, the trigger position of the solid state panel is obtained according to the signal output by the deformation sensor. By adopting the scheme in the invention, the deformation signals which are generated by non-contacts and inducted by the deformation sensor can be effectively removed and the device provided by the invention has the function of resisting external interferences.

Description

technical field [0001] The invention relates to the field of electrical digital data processing, in particular to an anti-interference coordinate input device and method. Background technique [0002] With the rapid development of electronic information devices, people's input interaction with electronic information devices is no longer limited to the operation of buttons, but more and more like to directly click the display screen to perform input interaction. [0003] In the prior art, a deformation sensor, such as a resistive sensor or a capacitive sensor, is placed on the display screen as a resistive touch panel or a capacitive touch panel, so that the user clicks on the touch panel with an input device such as a finger or a pen. Finally, the coordinate value of the click can be calculated through the electrical signal generated by the sensor, and then the human-computer interaction can be realized through the display screen. [0004] However, in the above solution, th...
