1. History LCD Projector

LCD projectors are found in New York by Gene Dolgoff. He began working at the college in 1968 and aims to produce a video projector in his idea would make an LCD that is brighter than the 3-CRT projectors. The idea is to use the elements referred to as "light valve" to regulate the amount of light that passes through it.

This will allow the use of a powerful external light source. After trying a variety of materials, he held the liquid crystal to adjust the light in 1971. It took him until 1984 to get the addressable liquid crystal display (LCD), which is when he built the world's first LCD projector. Upon examination, he saw many problems to be corrected, including large losses. He then used the new method to create high efficiency to eliminate the appearance of the pixels. He began working in Projectavision Inc. in 1988, first established the world of LCD projector.
