Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] The "main touch positioning system" described in the embodiments of the present invention refers to a touch system capable of positioning touch objects, which is used to locate touch objects to obtain preliminary position information of touch objects, such as electronic whiteboards, resistive touch screens , surface capacitive touch screen, projected capacitive touch screen, optical touch screen, surface acoustic wave touch screen, bending wave touch screen, etc., but the main touch positioning system does not include infrared touch screen.

[0019] figure 1 It is a schematic structural diagram of a touch system according to Embodiment 1 of the present invention. The touch system includes a main touch positioning system, an infrared pair tube array and a processing unit 107 . The main touch positioning system in this embodiment is an op...

Abstract

The invention discloses a touch system and a multi-point positioning method. The touch system comprises a main touch positioning system, a pair of infrared geminate transistor arrays and a processing unit, wherein the main touch positioning system is used for positioning a touch object to obtain the preliminary introduction position information of the touch object; the infrared geminate transistor arrays are used for acquiring the one-dimension position information of the touch object; and the processing unit is connected with the main touch positioning system and the infrared geminate transistor arrays, and is used for confirming the position information of the touch object according to the preliminary position information of the touch object and the one-dimension position information and sending the position information to a main controller. By using the touch system and multi-point positioning method provided by the invention, a ghost point can be eliminated effectively, and the multi-point positioning is realized.

Description

technical field [0001] The invention relates to the technical field of photoelectric detection, in particular to a touch system and a multi-point positioning method. Background technique [0002] As the latest computer input device, the touch screen is no longer a dispensable thing for computers in various application fields, but an indispensable device. It greatly simplifies the use of computers, even people who know nothing about computers can still use them at their fingertips, making computers more attractive. It solves problems that cannot be solved by computers in the public information market. [0003] For a long time, the touch screen market has been in a colorful situation, and touch screens using different technologies are suitable for different application environments. But now most touch screens can only solve single-point positioning on the touch screen, and it is difficult to achieve multi-point positioning. Contents of the invention [0004] The object of...
