Color display and solar cell device
First Claim
1. A device comprising:
- a color display comprising a liquid crystal display panel having a back plate and a front plate that are substantially transparent, and having a pattern of liquid crystal pixels, a polarizer, and a pixelized color reflector disposed substantially parallel to the back plate of the display having a pattern of color band pixel reflectors that corresponds to the pattern of liquid crystal pixels; and
a solar cell having a substantially uniform dark-colored light-receiving active surface disposed proximal to a back plate of the pixelized color reflector such that at least some light passing from the front plate and through the back plate of the pixelized color reflector will illuminate the light-receiving active surface.

Abstract
Color displays such as color liquid crystal displays (105) and touch sensitive displays (510) include a substantially transparent back plate (120) or backside and are stacked with one or more solar cells (150) such that light passing through the displays will illuminate the light receiving active surface of the solar cells (150). A pixelized color reflector (121) is used that comprises a patterned color reflector. The resultant display/solar cell can be utilized in combination with a portable electronic device (720) such as a wireless communications device, with the solar cell (150) providing electricity to the display (710), the portable electronic device (720), or both. A mask (810) can be used to occlude surface features on the solar cell (150) as appropriate to provide a substantially uniformly colored appearance.

10. A device comprising:
-
a touch sensitive display having a substantially transparent backside;
a color display comprising a liquid crystal display panel having a back plate and a front plate that are substantially transparent, and having a pattern of liquid crystal pixels, a polarizer, and a pixelized color reflector disposed substantially parallel to the back plate of the display having a pattern of color band pixel reflectors that corresponds to the pattern of liquid crystal pixels; and
a solar cell having a substantially uniform dark-colored light-receiving active surface disposed proximal to a backside of at least one of the pixelized color reflector and the touch sensitive display such that at least some light passing through at least one of the display and the touch sensitive display will illuminate the light-receiving active surface. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
