DLP TV technology stands for digital light processing. It uses an
optical semiconductor as a means of digitally manipulating light. DLP TV
is considered one of the most reliable technologies in the world. It is
the only display solution capable of mapping a digital connection
between a graphic or video source and the screen in front of you. This
result? Very high picture quality.
The magic bullet of DLP television technology is the Digital
Micromirror Device. Dr. Larry Hornbeck of Texas Instruments invented
this device in 1987. Think of the DMD chip as a highly sophisticated
light switch. The chip contains about 1.3 million hinge-mounted
microscopic mirrors.
Each of these micromirrors is less than one-fifth the width of a
human hair. When you coordinate a DMD chip with a digital video or
graphic signal, a light source, and a projection lens, these mirrors
reflect an all-digital image onto the screen. The result is superior
picture quality. Currently, Samsung DLP and Samsung HDTV are industry
front-runners in the use of this technology.
Since most people's eyes are capable of blending colors, individual
red, green, and blue pixels that appear on a DLP TV screen will usually
go unnoticed. However, some people see rainbows when they watch a DLP
projection. The rainbow effect only occurs in DLP systems that use a
segmented color wheel. It will not happen if you use a system that uses
one DMD for each primary color. Many home theater systems use color
wheels that contain segments in order to reduce the rainbow effect. Some
also add a dark green segment, which can often improve the overall color
quality.
