This morning I was amongst a select few fortunate enough to get a demonstration of SIM2's high-end high definition video projectors in the most appropriate surroundings of the British Film Institute in London.
There was a lot to take in, including 4 of their latest projectors (HT5000, HT3000), all of which SIM2 say push the boundaries of digital projection.
The star of the show is their latest HT5000 "Grand Cinema" 1080p 3-chip DLP projector - currently the only one of its kind in the world.
The presentation began with Texas Instruments' - who make the Digital Micromirror Device (DMD) - explaining why they believe the DLP system provides the best possible projection experience.
There are various reasons, with a lot of explanation, but basically it boils down to the following reasons:
Aperture
DLP projectors typically have at least 90% active area, compared to 60-75% with LCD technology.
Native Contrast Ratio
Typical 2000:1, compared with around 800:1 for LCD.
Video Speed
DLP produces an image that updates 1000x faster than LCD - we're talking nanoseconds not milliseconds.
Reliability
Very little colour decay on a DLP compared to LCD due to the technology being used.
TI say that Europe is now the biggest market for these type projectors, with 55% market share, particularly because of the education market.
BrilliantColor
They then went on to explain the BrilliantColor system which they say increases the colour gamut.
They use various systems depending on the application. There's the well-known three colour wheel (red, green and blue), a wheel where secondary colours (yellow, cyan, magenta) are also used, and another wheel having a white portion.
Well, that's the technology in a nutshell (it provided a good overview but I know you're all HD aficionados here so I won't write any more about this)
(There's a lot of DLP information at the TI site if you want to know more)
In the next article I'll move on to the star of the show...
