Problems solved by technology

[0004] Due to the good collimation of the laser and the small focused spot, some optical touch panels use laser light sources, but the laser is also easy to cause strong damage to the retina and skin of the human eye

Abstract

The invention provides a touch module and an operating method thereof. The operating method includes the steps of detecting a touch point and judging whether the touch point is under normal touch or not according to results of detecting the touch point; if not, decreasing the intensity of infrared laser of the touch module; if yes, judging the position of the touch point. Therefore, damage caused by the infrared laser to human vulnerable parts during abnormal touch can be decreased or avoided.

Description

technical field [0001] The present invention relates to a touch module and its operation method, and in particular to an infrared laser touch module and its operation method. Background technique [0002] The touch technology simplifies the communication of the man-machine interface, and the user can control the electronic device by finger touch to perform corresponding operations. Touch panels can be roughly classified into resistive touch panels, capacitive touch panels, optical touch panels, acoustic touch panels, and electromagnetic touch panels. Since the touch mechanism of the optical touch panel is suitable for large-size display panels, the touch function of the large-size display panel is mostly achieved through the optical touch mechanism. [0003] In terms of optical scanning touch technology, the main components include light source, micro-mechanical lens, photosensitive IC and photosensitive semiconductor array. The light emitted by the light source is reflect...
