DLP - LCD Guide
Invented by Dr. Larry Hornbeck of Texas Instruments in 1987 and then developed
by the company in mid-1996, DLP models project images by reflecting light against
hundreds of tiny mirrors known as digital micro-mirror devices (DMD).
DMD Micro-Mirror
It is a proven and dependable technology preferred by leading electronics companies
worldwide, with more than 1.5 million systems shipped to more than 50 manufacturers
since 1996.
How does DLP work ?
The DMD chip is probably the world’s most sophisticated light switch. It contains a
rectangular array of up to 1.3 million hinge-mounted microscopic mirrors; each of
these micro-mirrors measuring less than one-fifth the width of a human hair, and
corresponding to one pixel in a projected image.
Each mirror is individually powered by electronics that
adjust the angle of the mirror according to the colour
being displayed.
Fundamentally, the mirror chip is a standard static memory
design. Memory bits are stored in silicon as electrical
charge in…
