Optical touch panel assembly and light sensor thereof
A light sensor includes a case, a light reflective layer and a light sensing component. The case has a light incident side. The light incident side is partially covered by the light reflective layer to cause the light incident side to form a light incident area uncovered by the light reflective layer and a light reflective area covered by the light reflective layer and located beside the light incident area. The light sensing component is disposed within the case and has a light sensing surface facing toward the light incident area. An optical touch panel assembly incorporating a plurality of the light sensors is also provided. The optical touch panel assembly includes a touch panel, two above-mentioned light sensors oppositely disposed at two sides of the touch panel.
