Problems solved by technology

[0004] The existing three-dimensional touch scheme based on ultrasonic waves (for example, patent publication number CN106843502A) has the disadvantage of being difficult to locate accurately due to complex interference media such as the human body in the touch area
[0005] Existing 3D touch solutions based on cameras (such as patent publication numbers CN103914152A, CN104199550A, and CN103488356A) have disadvantages such as blind spots or excessive device volume, low touch accuracy, poor realizability, inconvenient standardization, or inaccurate touch.

Abstract

According to the three-dimensional touch device, cameras are symmetrically arranged outside the four corners of the back face of a three-dimensional touch area cube in front of a display panel 1 respectively, the included angles between the axes of the cameras and the back face of the three-dimensional touch area cube are 45 degrees, and the cameras face the three-dimensional touch area cube. Wherein the axes of the cameras are equal to two side lines of a corresponding angle on the back surface of the three-dimensional touch area cube, and the distances between the cameras and the vertexes of the corresponding angles on the back surface of the three-dimensional touch area cube are equal and are equal to the back surface distance; the cameras have the same specification, and the acquisition angle is greater than or equal to 90 degrees; the cameras are respectively connected with the image processing module 2; two cameras on the side of the back of the three-dimensional touch area cube determine touch coordinates of a half area of the opposite side of the three-dimensional touch area cube in front of the display panel 1. The three-dimensional touch device has the advantages of being small in blind area and size, more accurate in touch, convenient to achieve, convenient to standardize, long in Z axis, capable of achieving more accurate touch and the like, and the universality of three-dimensional touch is improved.

Description

technical field [0001] The invention relates to a touch screen, in particular to a three-dimensional touch screen, and belongs to the field of information technology. Background technique [0002] With the development of touch technology, touch screens are more and more widely used, but they are mainly two-dimensional flat or curved touch screens. The current touch screens mainly include surface acoustic wave, infrared, resistance, capacitance and other types. Their common characteristics belong to two-dimensional flat touch screen or curved touch screen. Pressure sensors are used to obtain a pressure-sensitive touch screen, or some touch screens are provided with pressure sensors to detect touch pressure, but these are not three-dimensional touch screens with spatial significance. [0003] The display technology naturally associated with touch screen applications is changing with each passing day. 3D display has become increasingly mature, and applications such as games, e...
