    • 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.
    • 被动日光灯耦合显示器,具有LCD面板,漫射器和LCD面板后面的弯曲反射器。 对于被动背光,扩散器将日光传输到反射器,反射器将日光反射到LCD面板,并且将日光基本均匀地分布在LCD面板上用于背光。 N堆叠日光耦合显示器包括级联在堆叠中的多个被动背光,用于LCD面板或静态显示面板的背光。 一个N堆叠显示器可以包括用于向反射器提供光的主动光源和用于向至少一个反射器提供光的次级光源,以在低照明条件下提供显示器的背光。 可折叠的日光耦合显示器包括在不用于手持或便携式显示设备的情况下可折叠的日光耦合背光。
