Liquid crystal projection system

Abstract

A liquid crystal projection system is composed of a unit for splitting a polarized light into a dual-prime-color light and a single-prime-color light, two polarizers for polarizing said two light beams, a color separator for separating said dual-prime-color light beam, an offset device for changing said two beams to another polarity and reflecting them out, a delay plate, and a projecting lens.

Description

technical field [0001] The invention relates to a liquid crystal projection system, in particular to a liquid crystal projection system using three reflective liquid crystal panels for image projection output. Background technique [0002] Traditional CRT monitors are limited by size and cost considerations, and it is difficult to achieve large-scale display effects. Therefore, using another liquid crystal projection technology can make the appearance volume thinner and smaller, and the projected display effect is not inferior at all. than traditional CRT monitors. [0003] The internal structure of the projector can be divided into two types: single-chip and three-chip according to its internal liquid crystal panel. The single-chip projector has low resolution and low brightness, but the price is cheaper, while the three-chip projector It has high resolution and high brightness, but the price is relatively expensive. Most of the currently used projection technologies are m...

Problems solved by technology

[0003] The internal structure of the projector can be divided into two types: single-chip and three-chip according to its internal liquid crystal panel. The single-chip projector has low resolution and low brightness, but the price is cheaper, while the three-chip projector It has high resolution and high brightness, but the price is relatively expensive. Most of the currently used projection technologies are mature transmissive projectors, but the transmissive projectors have the problem of low aperture ratio.
