Televisions New Technology


HDTV

High Definition Television, or HDTV, is high- resolution digital television combined with Dolby Digital surround sound. HDTV is the highest DTV resolution in the new set of standards.

DLP (Digital Light Processing)

Digital Light Processing, or DLP, projectors provide a premium picture quality via the latest technology in a small, lightweight package. These projectors use a digital micro-mirror device to create images, which are then enlarged to fill a screen.

LCD (Liquid Crystal Display)

LCD Projectors use LCD panels to create images, which are then enlarged to fill a screen. Most LCD panels are backlit and act as shutters to selectively block off light and create images. Three black and white panels are used, and the white light from the lamp is separated into red, green, and blue beams. These beams are fed separately through the panels and then recombined to create the full color image.

Plasma

Plasma TV’s are incredibly thin display monitors that can be hung on your wall just like pieces of video art. The display itself consists of thousands of cells, which are individual glass compartments injected with neon-xenon gas suspended in plasma. These cells are the basic elements comprising the picture you see on your TV screen. When the gases are electrically charged, they strike red, green, and blue phosphors and just like that, an image is born.
