Display resolution enhancement with optical scanners.
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.
