ABSTRACT:
A display (200) with aligned optical shutter and backlight cells (239, 289) uses a patterned polymer-dispersed liquid crystal (PDLC) optical shutter material (230) and an electroluminescent (EL) backlight material (280) to provide a low-cost, low-current-drain display having good contrast in both bright-light and low-light conditions. The aligned, patterned optical shutter and backlight layers form pixel “windows” through which images printed on a background can be hidden or revealed. Specifically, a mask layer (250) bears the images and is inserted between the optical shutter and the backlight layers to show information images, cover inactive areas of the display, and cover electrode traces connecting active segments of the display. The display (200) is thin and flexible enough to be integrated with a touchscreen (290).
