DLP Overview
Since 1996, over 5 million DLP- based display
products have been shipped by over 50 different
manufacturers
DLP Front Projection now account for more than 1
out of every 3 projectors sold
DLP TVs now selling in more than 5800 stores with
more than 50 models expected in 2004
DLP Cinema now over 220 screens in 20 countries

24
Characteristics of DLP Technology
1 Image Quality - pixelization (fill
factor) - contrast ratio -
sharpness (color alignment) - video
quality - color quality

• The level of Pixelization in a system is a result
  of the pixel geometry and architecture
• DLP small gap, large element
• COMP (LCD) larger gap, small element

25
Characteristics of DLP Technology

- color quality
26
Characteristics of DLP Technology
1 Image Quality - pixelization (fill
factor) - contrast ratio -
sharpness (alignment) - video quality
- color quality

• DLP simple optics easier light management
• COMP (LCD) complex optics more difficult
  light management

DLP higher uniformity
27
Characteristics of DLP Technology
1 Image Quality - pixelization (fill
factor) - contrast ratio -
sharpness (alignment) - video quality
- color quality

• DLP no misalignment sharp
• COMP (LCD) potential misalignment especially
  over time

28
Characteristics of DLP Technology
1 Image Quality - pixelization (fill
factor) - contrast ratio -
sharpness (alignment) - video quality
- color quality

• DMD switching is fast with minimal lag (few
  microseconds)
• COMP (LCD) switching is slower (tens of
  milliseconds)
• Result is NO smearing in DLP projection of
  fast moving video

Characteristics of DLP Technology
2 Weight/Physical Size

• LCD
• Three panel Complex optics
• Transmissive Loss of Light

• DLP
• Single panel simpler optics
• Reflective greater efficiency

31
Characteristics of DLP Technology
3 Repeatable Performance (Digital accuracy)

• Digital (DLP) precise control (not susceptible
  to changes)
• Analog (LCD) variable (affected by temp,
  vibration, heat, humidity)
• Digital (DLP) constant performance over time
• Analog (LCD) deterioration over time

32
Characteristics of DLP Technology
4 Reliability

• Superior thermal characteristics
• DLP reflects heat
• COMP absorbs heat
• Testing indicates DLP panels do not degrade as a
  function of use
• No Color space warp over time
• No Burn in images (no gaming)
• DMDs have shown consistent robust performance
  over time with up to 100,000 hours lifetime

33
Characteristics of DLP Technology

• One-Chip Systems Front Projection (Conference
  Room, Mobile, Home Entertainment)
• One-Chip Systems Rear Projection Television
• Three-Chip Systems Front Projection (Pro-Venue

34
DLP TV Value Proposition
Characteristics of DLP Technology

• Best Image Quality
• DarkChip2 and DynamicBlack for contrast ratios
  exceeding 50001
• SmoothPicture for smooth, seamless yet sharp
  picture
• Thin Elegant Designs
• Pedestal design
• Lightweight aesthetic styling
• Half the price of PDP

36
Digital Cinema Projection Technology Benefits -
Audience

• Constant opening night image quality experience
• Eliminates dirt, scratches, faded color
• Better than film experience
• Eliminates jump, weave, focus flutter, flicker
• Gives audience the aesthetic experience that
  director cinematographer intended
• Duplication quality consistency
• No more release print variations (color,
  contrast, grayscale)
