Problems solved by technology

[0002] Usually touch screen positioning methods include: capacitance, resistance, infrared, camera and other positioning methods, but the touch screen using these touch screen positioning methods cannot be made very large, generally around a few inches to tens of inches
At present, for small-size touch screens, resistive touch screens or capacitive touch screens are generally used to locate touch points. If resistive and capacitive touch screens are designed as large screens, the cost will be very high; while large-size touch screens generally use cameras or infrared frames. positioning, but the positioning accuracy is poor, and the touch point response is slow

Abstract

The invention provides a touch screen positioning device. The touch screen positioning device comprises a screen frame, wherein the screen frame is arranged on a touch screen in a sleeved mode, and the surface of the inner side of the screen frame contains a layer of ultrasonic absorption material. The touch screen positioning device further comprises at least one ultrasonic detection device, wherein the ultrasonic detection device is arranged on one of the top points of the touch screen in a rotatable mode, the ultrasonic detection device is connected with a control system of the touch screen, and the control system is used for obtaining the coordinate of a touch point according to the touch point distance detected by the ultrasonic detection device and the rotating angle of the ultrasonic detection device. The invention further provides a touch screen positioning method, and according to the touch screen positioning method, the super-large touch screen can be rapidly positioned, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a touch screen positioning device and a touch screen positioning method. Background technique [0002] Usually the touch screen positioning methods include: capacitance, resistance, infrared, cameras and other positioning methods, but the touch screens using these touch screen positioning methods cannot be very large, generally about several inches to tens of inches. At present, for small-size touch screens, resistive touch screens or capacitive touch screens are generally used to locate touch points. If resistive and capacitive touch screens are designed as large screens, the cost will be very high; while large-size touch screens generally use cameras or infrared frames. To locate, but the positioning accuracy is poor, and the touch point response is slow. Contents of the invention [0003] Based on this, the present invention provides a touch screen positioning device ...
