Abstract:
A semitransparent display (100), suitable for use with an electronic device (700), is provided. The semitransparent display (100), in one embodiment, includes a cholesteric liquid crystal display layer (101) and a translucent electroluminescent layer (102), such as an organic light emitting diode device. Control circuitry (109) is coupled to each layer, and is configured to selectively actuate each layer. The cholesteric liquid crystal display layer (101) can be operated in any of a planar mode (201), a focal conic mode (202), or a homeotropic mode (203). Segments of the cholesteric liquid crystal display layer (101) can be selectively actuated so as to hide and reveal user actuation targets. Capacitive sensors (620,621) can be included so that the semitransparent display (100) works as a touch sensitive user interface. A user can see an object, such as a hand (105) or stylus, from above the semitransparent display (100) when the hand (105) or stylus is placed beneath the semitransparent display (100).
