AB  - We have developed a prototype high-definition imaging system using 
      polymer-dispersed liquid-crystal (PDLC) light valves, which can modulate 
      unpolarized light with high spatial resolution and exhibit a high optical 
      efficiency, based on the light-scattering effect. We fabricated high-definition 
      light valves with a fine polymer-matrix structure in a PDLC film by controlling 
      the curing conditions used during the photopolymerization-induced phase 
      separation and formation process. This device has excellent characteristics, such 
      as a high resolution, with 50 lp/mm for a limiting resolution and greater than 20 
      lp/mm at the 50% modulation transfer function point, and a reflectivity of 
      greater than 60%. An optically addressable full-color projection display was 
      designed, consisting of three PDLC light valves, a schlieren optical system based 
      on shift-decentralization optics with a xenon lamp illumination and input-image 
      sources with 1.5 million pixels, including electrical image compensation of the 
      gamma characteristics. We succeeded in displaying pictures on a 110-inch screen 
      with a resolution of 810 TV lines and a luminous flux of 1900-2100 American 
      National Standards Institute lumens.
