Light Engines
The CRT technology used in the V27 chassis is electri-
cally the same as the V25 chassis. Since the V25 Train-
ing Manual covers it in-depth, no further discussion will
be necessary.
LCD, DLP and LCoS are known as “Micro-Display”
technologies. The Light Engines are configured differ-
ently for each.
LCD uses the “light transmissive” method of producing
a picture as light passes through the panel. DLP and
LCoS use the “light reflective” method of producing a
Figure 1-1: LCD Light Engine
picture as light reflects off the surface of the display de-
vice.
An LCD must use 3 devices to produce a color picture.
DLP and LCoS can be configured as either single, or 3
device engines. Mitsubishi currently uses a single chip
DLP and a 3 chip LCoS system.
The LCD Light Engine, shown in
Figure 1-1,
uses 3
LCD “Panels” to individually produce the red, green
and blue elements of the picture. Dichroic mirrors sepa-
rate the red, green and blue elements of light, and an X-
Prism is used to re-combine the 3 colors after the pic-
tures have been produced.
