Before I get back to finishing the story about how pico projectors can be “useful,” I wanted to say a few things about the KGonTech blog and address some comments that have been made both public and private.
I’m happy to discuss and defend my statements but don’t ask me to reveal confidential information. Also if you disagree with something that I’ve written, please be specific about where you think I am wrong. I do occasionally make mistakes.
If you don’t believe that I have a good idea of what is going on with lasers in spite putting together Syndiant’s CES 2011 demonstration of the first side by side projection with direct blue and green lasers from Soraa, OSRAM, and Nichia (see picture above), then there is nothing I can do to help you. I also can’t help that some companies, in my opinion, are giving the perception that the direct diode green lasers are much farther along that what the laser companies have personally told me.
As big a proponent of laser projection as I am, I don’t think it does the pico projector industry any good to set unrealistic expectations for the volume production of green lasers. It’s simply not realistic to think that a product that can’t be built today with the efficiency and brightness required at any cost, is suddenly going to be mass produced in less than 1 year. The burden of proof should be on anyone that says that it can be done.
Since there seems to be a lot of interest in laser projection today both in general (and I was the lead author of a distinguished paper at SID this year on the subject — click here for the paper itself) and in the comments on this blog, I am starting to work on a series of blogs to explain the basic issues and numbers with laser projectors. It is not going to be a technical deep dive, but rather a discussion of the common issues and what can be expected in terms of light efficiency. Its going to take a series of blogs that I plan to combine into one article as the blogs are posted. I’m not going to divulge any secrets, but I hope to put some good layman level information in one place so people can intelligently draw their own conclusions.
I plan on starting the laser information series next week and maybe I will do one or two a week for a while until I feel I have fully covered the subject.
One last thing don’t have a “short interest” in any stock and anyone that says or implies that is promoting a falsehood. I’m fond of saying that you never know when a dumb rich person will buy a company (I’ve seen it happen a few times).
