1. A method of sensing touch on a display device having an optical sensing frame comprising:
- emitting first light from a sensor module;
receiving a first reflection at the sensor module;
emitting second light from a waveguide;
receiving a second reflection at the waveguide; and
if a touch is made on an optical sensing frame;
detecting that reflections of the first and the second light are interfered, anddetermining a change in the quantity of the first and second reflection received to determine the touch.

Abstract
A method of sensing touch on a display device having an optical sensing frame includes emitting first light from a sensor module, receiving a first reflection at the sensor module, emitting second light from a waveguide, receiving a second reflection at the waveguide, and if a touch is made on an optical sensing frame, detecting that reflections of the first and the second light are interfered and determining a change in the quantity of the first and second reflection received to determine the touch.

10. A display device including an optical sensing frame, comprising:
-
a display panel; two optical sensor modules disposed on the display panel operable to emit first light and receive a first reflection; a wave guide disposed at a side of the display panel for emitting second light and receiving a second reflection; and an optical reflecting member disposed at each of the remaining sides of the display panel for reflecting the first light as the first reflection and reflecting the second light as the second reflection. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
