レーザ光バックライトスキャン方式による液晶ディスプレイ

Abstract

We developed an image display system which turns the back light of an LCD into a laser light source, and 2-dimensionally scans the back light. The system consists of a liquid crystal panel, a laser light source, a laser light source power control, and a 2-dimensional scanning mechanism. We achieved highly efficient image display properties shown below by this system. The system expanded the color reproduction region to 189%, shortened the Moving Picture Response Time to one half, and improved the contrast ratio to 6753:1.
