Abstract: A liquid crystal display device (30) that is illuminatable by diffuse ambient light comprises a liquid crystal panel (32) and a reflective holographic optical element (34). Diffuse ambient light illuminating the front side (36) of the liquid crystal panel and traversing the liquid crystal panel is received at a reflection site (66) and is redirected with a reflection pattern (68) to retraverse the liquid crystal panel to form a bright pixel for a display. By concentrating diffuse light within a preferential reflection pattern, the reflective holographic optical element provides enhanced brightness for viewing the display under ambient light conditions. In one aspect, the reflective holographic optical element is a transflector (158, 208) and is combined with an internal light source (170, 220) for illuminating the display using either reflected ambient light or backlighting.

Abstract: A liquid crystal display device (10) includes a liquid crystal panel (12), a switchable holographic optical element (14), and a reflective holographic optical element (16). A front polarizer (18) polarizes ambient light and transmits the light to the liquid crystal cell (20), which receives the light and transmits polarized light to a back polarizer (22). The back polarizer (22) polarizes the light and transmits the light to the switchable holographic optical element (14), which, in a first mode, redirects the light within a first viewing cone (34). In a second mode, the switchable holographic optical element (14) is transparent and transmits the light to the reflective holographic optical element (16). The reflective holographic optical element (16) redirects the light in a second viewing cone (36). The second viewing cone (36) is preferably narrower than the first viewing cone (34), which increases the light intensity within the second viewing cone (36).

Abstract: Displays such as liquid crystal displays (10), organic light emitting diode displays, and touch sensitive displays (41) are stacked with one or more solar cells (15) such that light passing through the displays will illuminate the light receiving active surface of the solar cells (15). No reflector or polarizer need be used when the liquid crystal display (10) uses cholesteric or polymer dispersed liquid crystals. When using supertwist nematic or twisted nematic liquid crystals, a reflector (21) can be used that comprises a selective color reflector. The resultant display/solar cell can be utilized in combination with a device such as a wireless communications device (62) with the solar cell (15) providing electricity to the display (61), the wireless communications device (62), or both. A mask (71) can be used to occlude surface features on the solar cell (15) as appropriate to provide a substantially uniformly colored appearance.

Abstract: A telepresence communications is provided at a virtual location between two or more participants at multiple locations (100, 200). First perspective data descriptive of the perspective of the virtual location environment experienced by a first participant at a first location and feature data extracted from features of a second participant at a second location (210, 220) are processed to generate a first virtual representation of the second participant in the virtual environment from the perspective of the first participant (250). Likewise, second perspective data descriptive of the perspective of the virtual location environment experienced by the second participant is processed to generate a second virtual representation of the first participant in the virtual environment from the perspective of the second participant (260). The first and second virtual representations are rendered and then displayed to the participants (260, 270).
