Abstract
An optical touch panel includes a frame, a first and a second image capture units, a first and second light sources, a first reflective element and a block element. The first and second image capture units are disposed on the frame and respectively disposed adjacent to the first and second light sources. The line between the first and second light sources defines a first connecting line. The reflective element disposed on a first side of the frame has a top point. The line between the top point and the second image capture unit defines a second connecting line. The block element blocks the first connecting line, but does not block the second connecting line.
