PASSIVE AND HYBRID DAYLIGHT-COUPLED N-STACK AND COLLAPSIBLE BACKLIGHTS FOR SUNLIGHT VIEWABLE DISPLAYS |
摘要 |
A passive daylight-coupled display having an LCD panel, a diffuser, and a curved reflector behind the LCD panel. For passive backlighting, the diffuser transmits daylight to the reflector, which reflects the daylight to the LCD panel and provides for substantially uniform distribution of the daylight on the LCD panel for backlighting it. An N-stack daylight-coupled display includes a plurality of passive backlights cascaded in a stack for backlighting of LCD panels or static display panels. One N-stack display can include an active light source to provide light to the reflectors, and a secondary light source to provide light to at least one of the reflectors to provide backlighting of the display in low lighting conditions. A collapsible daylight-coupled display includes a daylight-coupled backlight that is collapsible when not in use for hand-held or portable display devices. |
