Projection HDTV - What Technology is Behind A Projection HDTV?

There are four main components to the Projection HDTV concept - the projector, screen, control panel, and the sound system. Each of these components can be purchased in one easy to install unit or individually. The main part of the set up is the projector. This is where all the system information is entered. There are two methods used to form the screen images. The most common is the LCD panel and the alternative is the reflective where a light is based off of a reflective chip.

Microelectromechanical systems (MEMS) is a digital micromirror that works with liquid crystals on silicon to cause the reflections to take place. Both of the methods are collected by the use of a lens. They are enlarged and then displayed on the TV screen. The transmittive and reflective projection in the projector is responsible for this process.

With projection HDTV the screen is very comparative to that found in a movie theatre. The control panel is a built in feature that you can control with the remote. There are core units that you can assess including a home theatre system and the video receiver. If you are using the projection HDTV in a conference room then the core will be the audio and your computer.

The projection HDTV speakers offer an advanced sound system that includes Home THX, Dolby 5.1 surround sound, and the Dolby Digital EX. The biggest selling projection HDTV on the market right now is the Samsung Tantus HCL473W. It features a 47" screen, auto focus, a fine pitch screen, and the 1,000 line resolution.
