Display Technologies; Ptv Product Line - Mitsubishi WD-52627 Training Manual

Display Technologies & PTV Product Line

Display Technologies

Mitsubishi's Digital Television Product Line for 2005-
2006 consists of several different display technologies.
They are categorized as either Rear Projection or Di-
rect View.
Rear Projection Television Technologies:
• CRT
• LCD
• DLP™
• LCoS
Direct View Television Technologies:
• Plasma
• LCD
This training manual is directed towards Projection Tele-
vision technologies.
Each technology offers its own strengths and weak-
nesses. Otherwise, only one type would need to be made
available. Understanding the differences in each tech-
nology will aid the technician when discussing a given
set's performance with a consumer. Tables 1-1 and 1-
2 outline some of the strengths and weaknesses of each
one. Of course, the strengths and weaknesses will change
as each technology evolves over time.

CRT Technology - V27 Chassis
This is the most mature technology of the four. It may
even be viewed as somewhat "low tech" by some
people. However, Mitsubishi's product line includes all
the latest digital features. As such, it can still offer the
best "bang for the buck" of all the technologies. The
V27 Chassis is used in 55", 65" and 73" models.
LCD Technology - V28 Chassis
While LCD projection television is certainly not new,
recent strides have improved this technology so that Mit-
subishi can offer it in 4 models this year.
DLP Technology - V29/V30/V31 Chassis
Mitsubishi, the first to bring DLP technology to market
in a rear projection television, marks another "first" by
introducing 1080p DLP in 9 different rear projection
models. This is twice the resolution of High Definition.
It will come in 52, 62 and 73 inch screen sizes, with the
73 inch models being the largest DLP models ever avail-
able.
LCoS
Mitsubishi's use of LCoS technology is in the form of a
3 chip system carried over in the 82" rear projection
model WL-82913.
