Optical touch control system and operating method thereof

Abstract

The invention provides an optical touch control system and an operating method thereof. The optical touch control system comprises a panel device and an optical touch control device. The panel device comprises a first position and a second position which are different. The optical touch control device comprises a light-emitting module, a light path adjusting module, a light-sensing module and a processing module, wherein the light-emitting module and the light-sensing module are respectively arranged in the first position and the second position, and the light-emitting module emits sensing light; the light path adjusting module reflects the sensing light so as to form reflected light; the light-sensing module receives the reflected light and produces a sensing result according to whether the light-sensing module receives the reflected light; and the processing module judges the position of a touch control point formed on the panel device according to the sensing result.

Description

Technical field [0001] The invention relates to a touch device, and in particular to an optical touch system and an operation method thereof that can integrate an optical touch device and a panel device to save space and expand the effective sensing area. Background technique [0002] Generally speaking, the more common touch devices currently include resistive touch devices, capacitive touch devices, and optical touch devices, which can detect single or multiple touch points through different detection principles and methods. . Among the above-mentioned various types of touch devices, optical touch devices have become a new alternative to traditional resistive touch devices and capacitive touch devices due to their excellent light transmittance. Commonly used techniques. [0003] Please refer to figure 1 , figure 1 It shows a schematic side view of a traditional optical touch device disposed on a panel. Such as figure 1 As shown, the conventional optical touch device 1 includes...

Problems solved by technology

[0004] However, by figure 1 It can be seen that since the optical touch device 1 is not integrated with the panel device 9, but only its light emitter 12 and light receiver 14 are simply arranged on the panel device 9, this will cause additional The space requirement is indeed quite unfavorable for the current electronic products that emphasize lightness, thinness and shortness

In addition, the arrangement of the traditional optical touch device 1 on the panel device 9 also limits the range of its effective sensing area.
