An optical touch panel and corresponding method are disclosed. The optical touch panel may comprise a rectangular position-detecting surface; a frame-shaped circuit board surrounding the rectangular position-detecting surface; a plurality of light-emitting elements configured for emitting a plurality of light beams, wherein the light-emitting elements are arranged along a first side of the rectangular position-detecting surface and disposed on the frame-shaped circuit board; a plurality of light-receiving elements configured for receiving light beams emitted by the plurality of light-emitting elements; a plurality of SMT components configured as optical gates for isolating ambient light to prevent erroneous light detection; and a control circuit. The plurality of SMT components and the plurality of light-receiving elements may be alternately arranged along a second side of the rectangular position-detecting surface opposite to the first side and disposed on the frame-shaped circuit board. The plurality of light-receiving elements may be arranged behind the plurality of SMT components.
