Abstract

An optical touch apparatus and a touch method thereof are provided. A plurality of light sensing units are disposed between a first scanning light source and a second scanning light source, wherein the light sensing units, the first scanning light source and the second scanning light source are disposed at a same side of a touch surface. A touch position of an input tool is determined according to an intensity of a scattered light generated by an input tool and sensed by the light sensing units and generated when a first scanning beam and a second scanning beam scan the input tool.

Description

technical field [0001] The present invention relates to a touch control device and a control method thereof, and in particular to an optical touch control device and a touch control method thereof. Background technique [0002] Optical touch panels generally use a light source and a light sensor at the edge of the screen, analyze the sensing results of the light sensor, and calculate the distance of the touch point based on the distance between the known light sources and the triangulation method. Location. The above-mentioned optical touch panel can achieve a certain touch accuracy in most cases. However, in the case of multi-touch, there is still a problem that the touch points cannot be correctly judged. [0003] Patents related to optical touch panels include US Patent Publication Nos. 20110261016, 20100201637 and 20120205166. Contents of the invention [0004] The invention provides an optical touch device and a touch method thereof, which can eliminate ghost point...
