Summary: | A liquid crystal display assembly (10) can function in either a transparent or reflective mode. The assembly consists of a reflective-type liquid crystal display cell (12) placed in front of an electrochromic panel (14). When a display driver (16) activates the electrochromic panel, it absorbs light. When the driver energizes segments (15) of the reflective-type liquid crystal display cell, they become reflective, providing a visual image to an observer. When the electrochromic panel is not activated by the driver, it is transparent or translucent, allowing the observer to see completely through the liquid crystal display assembly. |
