3. An Inside Look on DLP Innovation
Originally developed by Dr. Hornbeck in 1987 for TI.
DLP and LCD are the two current display technologies behind rear-projection television .
These two as well as plasma gas technology are the competitors in the HDTV market.
It's About the Mirrors

4. The Key Component – A Digital Micromirror Device
Image is created by numerous microscopic mirrors on semiconductor chip.
The number of mirrors corresponds to the resolution of the projected image
Mirrors are repositioned rapidly to create image

5. Color in DLP Technology
There are two primary methods by which DLP projection systems create a color image
single-chip DLP projectors
three-chip projectors

6. Single-Chip DLP Projectors
Colors are produced by placing a spinning color wheel between the lamp and the DMD
The color wheel is usually divided into four sectors

7. The Unique Color Wheel Divided into four color sections
Red, green, blue and additional clear strip to boost brightness
Clear strip has been known to reduce saturation
Some color wheels substitute additional colors such as yellow instead of clear stip

8. The color process cont.
DMD chip is synchronized with the high-rotation rate of the wheel to produce a “full color” image
Older wheels rotated once per frame while newer models are capable of rotating six times per frame

9. Three-Chip Projectors
projector uses a prism to split light from the lamp
each primary color of light is then routed to its own DMD chip
They are then recombined and routed out through the lens

11. Pros and Cons to DLP technology
Smooth 1080p jitter-free image
Considerably cheaper than LCD and Plasma
Replaceable light source provides longer life than CRTs and plasma displays
Lighter weight than LCD and Plasma televisions
Cons
In single-chip designs, some viewers are bothered by the "rainbow effect”
Some viewers experience eye strain, headaches, and migraines when viewing
Poor viewing angle compared with direct-view technologies such as CRT, Plasma, and LCD

12. Distribution of TV models relative to size

13. A Look at the Competition
Many tiny cells located between two panels of glass hold an inert mixture of noble gases
The gas in the cells is electrically turned into a plasma which then excites phosphors to emit light.
Plasma has turned out to be the higher priced option for HDTVs in the current market

14. Competition continued
Liquid Crystal Display
based on the properties of polarized light
Two polarized panels sandwich a thin liquid-crystal gel that is divided into individual pixels
LCD has been implemented widely among flat panel computer monitors as well as HDTVs
Plasma Technology
Many tiny cells located between two panels of glass hold an inert mixture of noble gases
The gas in the cells is electrically turned into a plasma which then excites phosphors to emit light

15. Conclusion
DLP HDTVs have set themselves apart from the competition by providing a ever more growing superior product for a fraction of the price.
This places them at the forefront of an ever growing and expanding market full of future potential.
