System and method for constructing optical devices using fold-up portions extended from a substrate

摘要

In one embodiment, the transmitters and detectors for an integrated optical touch panel (OTP) are mounted at right angles to the surface of the OTP. The transmitters and detectors are contained on a substrate which is an extension of the substrate containing the touch panel display itself. The sides of the substrate containing the transmitters and detectors are folded upward so that the transmitters and detectors are positioned above the plane of the substrate containing the display.
