Learn How the TV Technologies Work
|
LCD TVs create images on their flat-panel displays by passing light through a layer of liquid crystal sandwiched between two panes of polarized glass.
Images on plasma displays result when electrically charged gases (or plasma) illuminate colored phosphors

Referred to as "traditional TVs," CRTs (cathode ray tube) create pictures by shooting an electronic beam at a phosphor-coated glass screen.
Large and heavy, many CRT rear-projection TVs use three cathode ray tubes to create images for their large, wide-screen displays.
DLP (Digital Light Processing) from Texas Instruments projects light from microscopic mirrors onto big, widescreen rear-projection TVs (or microdisplays).
Liquid crystal display microdisplays house not one but three LCDs in order to create HDTV-quality pictures.
A more recent technology, LCOS (liquid crystal on silicon) differs from DLP and LCD in that it is both reflective and transmissive.
