LightView™ VGA Digital Display Panel

Model LDP-VGA

 

Summary

The Displaytech LightView™ VGA is a compact, low power display Panel designed for a wide range of magnified color display applications including micro-projection, head mounted displays, and electronic viewfinders. The LightView™ VGA is an integrated display solution, incorporating the display panel and control circuitry in a compact package. This product takes advantage of the fast switching speeds and superior optical qualities of our patented Ferroelectric Liquid Crystal (FLC) materials, delivering full color video images free of motion smearing. The small size of the display allows for innovative end product designs while the low power consumption extends product battery life. Industry standard digital interfaces are supported for easy product integration.
