1. An optical touch panel assembly comprising:
a touch panel; two light sensors oppositely disposed at two sides of the touch panel, each light sensor comprising: a case having a light incident side facing toward the touch panel; a light reflective layer covered on parts of the light incident side 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, wherein a majority portion of the light incident side is covered by the light reflective layer to form the light reflective area for reflecting light, and a minority portion of the light incident side is uncovered by the light reflective layer to form the light incident area for allowing light passing through; and a light sensing component disposed within the case and having a light sensing surface facing toward the light incident area; and two light sources respectively disposed on two outer surfaces of the cases of the light sensors, the outer surfaces opposite and parallel to bottom surfaces of the cases, and the bottom surfaces resting on the touch panel, wherein the light source disposed on the outer surface of one of the cases is configured to directly emit a light into the light incident side of the other one of the cases and the light reflective layer covered on the light incident side of one of the cases is configured to reflect the light emitted by the light source disposed on the outer surface of the other one of the cases. |
