Abstract

A flat panel display has a linear array of switchable light emitting diodes (“LEDs”) to emit bands of light across the display, providing a light pattern programmable at video frequencies and a two-dimensional electropolymeric shutter array to convert the light pattern into a video image. The light pattern can be varied or controlled spatially, with respect to both hue and intensity, by suitable drive signals, at points along the array determined by the location of individual LEDs, or groups of LEDs, and temporally as the shutters in the array are opened and closed to provide a pleasing full color gamut for every pixel in the display. Closed shutters, displaying a reflective appearance, can be employed for background or other effects. The shutter array can be flexibly constructed and supported on a flexible substrate to provide a flexible display.
