OPTICAL TOUCH DEVICE, CORRECTION ELEMENT, AND CORRECTION METHOD THEREFOR

摘要

An optical touch device configured to cause a display surface to from a touch surface. The optical touch device includes a non-visible lighting element, a non-visible sensing element, and a correction element. The non-visible lighting element is adjacent to the display surface and forms a non-visible light curtain in front of the display surface. The non-visible lighting element is disposed in front of the display surface and has a sensing area covering the display surface. The correction element is disposed on the display surface and includes a bottom layer placed on the display surface and a plurality of reflecting blocks disposed on the top surface of the bottom layer. The correction element of the optical touch device has long-life. A correction method for an optical touch device is also provided.
