Title: Energy-efficient full-color liquid crystal display

Abstract: Novel liquid crystal display (LCD) structures for full-color liquid crystal displays using photoluminescent (PL) fibers. The new architectures simplify the LCD fabrication process by replacing complicated, time consuming photolithography steps for color filter fabrication to a low-cost, high-throughput fiber spinning technology. The new LCD architecture implementing the approach has a higher power efficiency than conventional LCDs. Three structures of LCD devices utilizing photoluminescent (PL) fiber arrays includes: a first structure having PL fiber arrays situated behind the LC shutter (relative to viewers); a second structure having PL fiber arrays situated on top of the LC shutter; and a third structure where the PL fiber arrays are located outside the LC cell. In one of these structures, the fibers not only photoluminesce, but also polarize incident light thus reducing LCD fabrication cost.
