The LCD backlight systems are made highly efficient by applying optical films such as prismatic structure (prism sheet) to gain the light into the desired viewer directions and reflective polarizing films that recycle the polarized light that was formerly absorbed by the first polarizer of the LCD (invented by Philips researchers Adrianus de ...
A liquid-crystal-display television (LCD TV) is a television set that uses a liquid-crystal display to produce images. It is by far the most widely produced and sold ...
James Lee Fergason [2] (January 12, 1934 – December 9, 2008) was an American inventor and business entrepreneur. A member of the National Inventors Hall of Fame, Fergason is best known for his work on an improved Liquid Crystal Display, or LCD.
1987 optical micro-electro-mechanical technology that uses a digital micromirror device. While the Digital Light Processing (DLP) imaging device was invented by Texas Instruments, the first DLP-based projector was introduced by Digital Projection Ltd in 1997.
The earliest version of the CRT was invented by the German physicist Karl Ferdinand Braun in 1897 and is also known as the Braun tube. [32] [33] Braun was the first to conceive the use of a CRT as a display device. [34] It was a cold-cathode diode, a modification of the Crookes tube with a phosphor-coated screen.
He then invented new optical methods to create efficient and bright projectors and invented depixelization to reduce the screen-door effect. Typical 3LCDs (RGB) projector showing separated polarizers At about the same time, the German company "Bonner Ingenieurbüro für Optoelektronik CrystalVision" started experimenting with LCD projection ...
In 1996, Samsung developed the optical patterning technique that enables multi-domain LCD. Multi-domain and in-plane switching subsequently remain the dominant LCD designs through 2006. [10] Later, LG Display and other South Korean, Japanese, and Taiwanese LCD manufacturers adopted IPS technology.
