Projection Summit 2011: Green lasers, “green” projectors, and etendue

Hello from the Orlando office -

This week’s Projection Summit 2011, an Insight Media event, offered a good view of topics of current interest to the A/V professional. (And by “A/V professional,” I mean: people who design digital projectors, buy digital projectors, make the guts of digital projectors, or love the Earth sufficiently to only buy digital projectors that don’t, you know, screw up our little planet.)

Normally I attend conferences like SPIE-IS&T SD&A, or SID, for their 3-D technical content. I was invited to speak at PS2011, and this was my first time attending.

The conference’s Agenda provides abstracts of each talk, so I won’t repeat that. Instead, here’s an overview, and an informal bullet point list of some key take-aways.

(Those take-aways are conveniently provided after this photograph of the impressively chocolatey brownies served at PS2011:)

So, what was covered at PS2011?

  • Autostereo 3D, emphasizing “light field displays:” OFH’s and Zecotek’s time-domain view-scanning systems, and Holografika’s advances in multi-projector 3-D display.
  • Tiled displays and stereoscopic projection (ROAM, Scalable, XpanD, Lightspeed Design, Brawn)
  • Projector components, emphasizing microdisplays, geometry-correction silicon, MEMS, and LEDs
  • Low-power Green Laser (Panel discussion). I learned too late that “green” here meant… the color green: #00FF00, 520 nm, you know.
  • Projectors in Education
  • Green AV (in which “green” meant earth-friendly)
  • Laser-based digital cinema

What were some key takeaways?

  • Gregg Favalora is a brilliant public speaker, and I understand he might be available for paid engagements on topics as diverse as: autostereoscopic display. With the deftness of an Olympic gymnast and the slight-of-hand of… oh, who am I kidding.
  • According to one speaker, JVC seems to be the gold standard of home 3D projection. (I have not heard this comment elsewhere.)
  • According David Chechelashvili of XpanD, the US stereo market is dominated by passive eyewear, Europe and Asia use active. So far.
  • Chris Ward of Lightspeed Design announced a new modulator with very fast rise- / fall-times for passive stereo projection.
  • Jonathan Brawn, who is well-known as an educator in A/V circles, is a really compelling speaker. Here, he explored the difficulties in designing projection systems optimized both for 2-D and 3-D, one of which requires different gain than the other.
  • Syndiant’s CTO, Karl Guttag, voiced a popular sentiment of Projection Summit – green (as in the color) lasers are a critical need in the world of projector components because of their etendue. (I knew I’d get that word in there somehow.)
  • I could listen to Luminus Devices’ Andrei Kazmierski talk for hours about LEDs (honest). Excited to see continued advances from this MASSACHUSETTS-BASED LED fabricator.
  • Ten lashes with a wet noodle for not knowing beforehand who William “Bo” Coggshall was, an eloquent industry analyst in the world of large-screen display. Also, props to a guy who synchronizes his wardrobe with his corporate logo. He discussed the market saturation of educational “interactive whiteboards and interactive projectors” (e.g. SMART Technology); UK & US is nearing saturation, and there’s a big opportunity in developing markets. Evidently there is a not-quite-closed tender in Turkey for 600k units…
  • Len Scrogan gave a fascinating talk about his efforts to guide Boulder, CO’s schools in testing the efficacy of stereoscopic projection. (Test scores have improved, behavior has improved, and kids with vision problems have gone to eye doctors and improved.) See: http://edtechfuture-talk.blogspot.com/ and www.3deyehealth.org .
  • Educators (who genuinely care about helping the earth) and large corporations (who might, but who also care about avoiding bad PR) want their new digital projectors to be eco-friendly. Does that mean the bulbs are recyclable? That the projectors lack Hg? Much discussion about this. Some claims that EnergyStar 2.0 is “useless” for defining requirements of A/V equipment; that Christie Digital is making incredible strides towards eco-friendliness; that TCO Development has a certification process for “…driving IT towards sustainable use…”. Particularly compelling talk from Chris Maione Associates. (It might have helped that his NYC intonation reminded me of my mother country of New Jersey.)

Until next time,

G-Fav
