How much do them replacement bulbs cost?

DLP in Imaging

One of the off shoots of this technology is in the digital imaging sector for photographic prints. In the late 90's A Swiss based company [Gretag Imaging] used DLP technology for the high speed digital printing systems. The DLP technology was fundamental in bringing about a revolution in consumer imaging providing for continuous printing, previously images were snapped one by one onto paper, laser and DLP technology changed that; with DLP making the most dramatic revolution in speed and reliability, the performance of these little chips is absolutely astounding. I often teased people that the Mario was constantly running around inside cleaning off the million mirrors and oiling the hinges.

I've got the fifty-something (52?) inch Samsung TVs lit by the LED DLP light engine and it has been spectacular for many years.  I often have people comment on the picture, asking me what kind of LCD TV it is, as it is "built in" with wooden paneling surrounding it.  My goal is to see how long I can make this TV last, as I think it was way ahead of its time. 

I also have a 150" screen that drops down in front of it so I can project TV from my DLP projector.  :)

Thanks Junko, a very enabling article. Opens my mind to all sorts of ideas.

That is very cool! Very true to the enigineer's hacking spirit and ingenuity.

The PCB application is very cool -- no photomasks! This is really clever repurposing of a technology that was developed for something completely different.

At one point my one of my fellow engineers and I delved into using a DLP as the heart of an N x M optical switch as well as combining it with an AWG to make an ersatz Optical Spectrum Analyzer. The first didn't work out so well due to problems with some of the optics (not the fault of the DLP), but the second application worked out well and we took it to its logical conclusion - a DWDM channel monitor. We have since gone beyond that original model and are using a MEMS tunable filter to acheive the same result.

Great to see DLP alive and well in other applications: thanks Junko. It's great technology. That food scanner will sell like hot cakes!

I got a 61-in Samsung 1080p DLP TV when it moved to an LED light source and it's been flawless in the 6 or 7 years I've had it.

Thanks. This story was a long time in making. Just like Rick, I used to think whatever happened to those DLP projectors everyone was supposed to have at home by now.

But then, last year, when I was interviewing TI on HUD (for automotive), I was made aware that DLP has morphed into an enabling technology in so many diffferent segments of the industrial market.

My hats are off to engineer hackers, who have ripped apart DLA and figured out what they can used it for. And more to the point, kudos to TI which was flexible enough  to open up the technology, make it easy for hackers to build their own products.

Loved the variety--holographic display especially!

Too bad DLP did not make it into high volume TVs. I guess LCDs won everything.

I remeber the days when there were at least a half dozen competitors including DLP. Where are they now?
