Abstract
We have developed a novel, low-cost, and effective technique for display resolution and fill-factor enhancement. By using optical scanners with fast nematic liquid-crystal polarization switches and birefringent materials, we have increased the perceived pixel count of a low-resolution display and also its display fill factor. The resulting display resolution was quadrupled by the optical scanners without increasing the display die sizes or input–output counts. The display optical system architecture, scanner design, packaging, and experimental results of the display system performance are discussed.
