DMD pattern rates in digital cinema projectors

Wolfgang Woehl

Hi,

Browsing these forums I realize that people do many fascinating things with DMDs and for most members cinema applications might indeed be the dullest thing. So thanks in advance for bearing with me and some cinema-specific questions.

I'm having a tough time looking for hard data/specs of the DMD devices used in digital cinema projectors. Essentially I'm looking for the maximum on/off rates of DMDs like the S2K DLP Cinema (used in projectors like Christie's Solaria One), the 1.38 DLP Cinema (used in Barco's DP4K-32B) or the .98 2K (used in Christie's discontinued CP-2000M).

For my understanding: Pattern rate or patterns/second means the number of times any single DMD micromirror can be in on-state during 1 second, yes?

It's is surprisingly hard to find that number for any of the various TI DMD devices. Thanks in advance for any hints or pointers.

Regards, Wolfgang

Hello Wolfgang,

First, Welcome to the DLP section of the TI-E2E Community. The Digital Cinema DMDs are handled by a DLP group decicated to this market through Digital Cinema Projector Manufacturers. These DMDs are not available to the Mass Market.

Actually, pattern rate and patterns/second refer to the rate at which the entire array can be refreshed. I do not have numbers for the Digital Cinema devices. You would need to contact our Digital Cinema Group.

For the devices that we offer to the Mass Market, please see http://www.ti.com/lsds/ti/analog/mems/mems.page?DCMP=standlinear_webcasts_2007&HQS=Other+OT+mems and look at the box on the left that lists "MEMS Devices".
