Problems solved by technology

[0004] However, there is a problem that in the prior art, the density of the optical network may be relatively small due to the relatively large spacing between parallel optical paths (forward scanning optical paths and oblique scanning optical paths), and some touch points (such as figure 1 Touch point 2 as shown and as figure 2 The touch point 4) shown may be missed due to being in the gap between adjacent parallel light paths and not blocking any light path, which will affect the positioning accuracy of touch points

Abstract

The invention discloses a touch screen positioning method, device and touch screen equipment, relates to the technical field of touch control, and aims to improve the positioning accuracy. The specific solution is: within one scanning period, scan in the first scanning direction and the second scanning direction; set a virtual parallel optical path, and obtain the first touch area, that is, in the virtual parallel optical path and the parallel optical path in the first scanning direction, The touch area formed by continuous adjacent optical paths blocked by the touch point; if the boundary optical path of the first touch area is any one of the virtual parallel optical paths, the boundary optical path of the first touch area is restored to the second scanning direction, and The optical path where the boundary optical paths of the first touch area intersect to obtain the second touch area; according to the candidate touch area, locate the real touch point, the candidate touch area includes the second touch area and / or the boundary optical path in the first touch area is the first scan Direction on the touch area of ​​either light path. The embodiment of the present invention is applied in the process of positioning the touch screen.

Description

Technical field [0001] The present invention relates to the technical field of touch control, in particular to a touch screen positioning method, device and touch screen equipment. Background technique [0002] With the introduction of a new type of human-computer interaction technology—touch screen technology, the input control mode of electronic products has gradually changed from the traditional keyboard or mouse control mode to the touch screen control mode. Compared with traditional input control methods, touch screen technology can provide users with more simplified human-computer interaction services. Among them, infrared touch technology is a common touch screen technology. The infrared touch screen adopted by the infrared touch technology has a rectangular structure. The infrared touch screen is composed of a long transmitting side, a long receiving side, a short transmitting side and a short receiving side. [0003] In the prior art, in the case of multi-touch point tou...
