Abstract
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.
Claims21
An integrated circuit assembly comprising:
- a substrate for mounting electronic components thereon, said substrate having defined thereon peripheral portions adapted for folding such that electronic components mounted on said defined portions will protrude above other components mounted on non-peripheral portions of said substrate when said defined portions are folded.
The method of constructing an electronic device, said method comprising:
- mounting electronic components peripherally on a flex circuit;
- mounting other electronic components centrally on said flex circuit;
- and
- folding along a fold line at least one peripheral edge of said flex circuit approximately 90° with respect to the non-folded portion of said flex circuit such that any peripherally mounted component which is mounted outward of said fold line is above the top surface of said centrally mounted components.
An electronic device containing an optical touch panel (OTP), said device comprising:
- a housing having an opening therein for framing said OTP;
- said OTP construction comprising:
- a substrate having mounted thereon at least the screen portion of said OTP;
- said screen portion having a top surface raised a distance “h” above said substrate;
- and
- said substrate having peripherally defined portions upon which are mounted light emitting devices and light detecting devices;
- said peripherally defined portions each having a width greater than said dimension “h” such that said light emitting devices and said light detecting devices are mounted outward of said dimension “h” on said peripheral portions;
- and wherein when said peripheral portions are folded said light emitting devices and said light detecting devices communicate light from said emitters to said detector above the surface of said screen.
