Dlp Tv vs Lcd Tv. DLP and LCD televisions are two emerging technologies competing for a place in every consumer's home theater.

DLP (Digital Light Processing) technology utilizes a small digital micromirror device (DMD) to tilt micromirrors less than the size of a human hair in width toward or away from a white lamp inside the DLP television. This process creates a light or dark pixel on the face of the projection screen, depending on how much light is reflected by the mirror.

Each mirror can turn on or off several thousands of times per second, so this technology can reproduce 1024 shades of gray. There are four main components in the system: the DMD chip, the colour wheel, the light source, and the optics. Light from the lamp passes through a colour wheel filter and into the DMD chip, which will switch its mirrors on or off in relation to the colour reflecting off them, producing an image.

Whether spread across a flat-panel screen or placed in the heart of a projector, all LCDs are pretty much the same. A matrix of thin-film transistors (TFTs) supplies voltage to liquid-crystal-filled cells sandwiched between two sheets of glass. When hit with an electrical charge, the crystals untwist to an exact degree to filter white light generated by a lamp behind the screen (for flat-panel TVs) or one shining through a small LCD chip (for projection TVs).
