Unlike most LCDs which are difficult to read in bright sunlight, the NCAPTM Plastic Liquid Crystal Display (Polymeric LCD) actually gets easier to read in brighter light (just like a piece of paper).

For informational displays with many separately controlled segments (such as a digital clock), each part of the liquid crystal panel can selectively be turned 'on.' Furthermore, the amount of translucency is proportional to the voltage applied.

Further Information  

The heart of the NCAPTM technology is the liquid crystal cell. Normally this cell is black, allowing almost no light through. But when a current passes through it, instantly it turns transparent. Behind this liquid crystal cell is a colored reflective pattern. When the cell turns transparent, the colored print beneath shows through.

NCAPTM plastic displays can be directly applied to where clear, bright displays / control panels are needed such as

  • Information displays
  • Automobiles
  • Gaming machines
  • Household appliances (e.g., microwave oven)
  • Biomedical instruments or other instrumentation
  • Point of sale

Some potential applications for applying the NCAPTM LCD cell include

  • Exhibit displays, billboards, schedule boards
  • Ski goggles, sunglasses
  • Automotive windows, portable sun shade / umbrella
  • Telephone booth, changing room, office window / surgery room, hide home entertainment center
  • Peek through oven window, transparent drawers / kitchen cabinets for easy searching
