How DLP Projectors Work?
DLP (Digital Light Processing) projectors can be attached with
computers, DVD players, VCR players, HDTV's and video games. It
comes in various models and with enhanced features. DLP
Projectors are also called as Multimedia projectors. In mid
1990's Texas Instruments developed Digital Light Processing. DLP
technology is based on DMD or Digital Micromirror Device. It is
a switch, which controls the intensity, and placement of
projected light via 4,80,000 mirrors. In a DLP-based display
there are unlimited colors. You can control the saturation and
clarity to make bright video as clear as you want. The DMD is
coordinated with a graphic signal, a light source and a
projection lens. The micromirrors of DLP are fixed on a panel of
small pivots, which enable them to slant either way. If it
slants towards (on) light source it creates bright pixels on the
screen and when it slants the other way
(off) it creates darker
pixels. When the bit-stream image code enters the semiconductor,
the semi conductor directs the switch to on or off. If the
switch remains on more times than off, it reflects a light gray
pixel. Otherwise it reflects darker gray pixel. In DLP systems
white light is passed through a color wheel and it runs to the
surface of the DMD panel. The color wheel converts the white
light into red, green and blue. From these three colors a DMD
chip can create 16.7 million colors. So a 3-DMD chip DLP system
can create a mammoth 35 trillion colors. Then our eyes
understand these colors and see an image.
