I received concerns that the chroma aberrations (color fringes) seen in the photos in Part 2B were caused by poor alignment of the lasers. I had aligned the lasers per Celluon’s instructions before running the test but I decided…
June 6th 2015 – Note, I am in the process of updating this analysis with new photos. The results are not dramatically different but I was able to improve the horizontal resolution slightly and now have some better pictures. …
The Celluon PicoPro projector has been out for a few months now for about $359. I have read a number of so-called “reviews” that were very superficial and did little more than turn on the projector and run a few…
Hi everyone, Just a quick note today to say that I no longer at Navdy and I now have some time to get back to posting on this blog. All the travel and work at a start-up was pretty all consuming.…
Its LAUNCH Day for Navdy as our presale campaign starts today. You can go to the Navdy site to see the video. It was a little over a year ago that Doug Simpson contacted me via this blog asking about how to make a aftermarket heads…
Back around 2007 when I was at Syndiant we started looking at the pico projector market, we talked to many of the major cell phone as well as a number of PC companies and almost everyone had at least an…
A reader, Doug Atkinson, asked a question about meeting extended temperature ranges with LC based microdisplays, particularly with respect to Kopin. He asked the classic “car dash in the desert and the trunk in Alaska” question. I thought the…
Sorry for being away from the blog so long. I had two big “consulting gigs” come in one right after the other and I have been working virtually non-stop for the last 6 weeks. There has been a lot of…
Microvision continues to make thinly veiled accusations against this blog in their May 9th, 2012 Company Displayground Blog (quoting directly with my bold emphasis added): “Our shareholders are following the topic of direct green lasers with avid interest and we…
First, sorry for being away so long. Some family and other matters took me a way and I fell out of the habit of posting. I am going to try to have at least couple of posts up a week.…
It’s nice to know that a CEO of a public traded company is following my blog. On today’s Microvision Conference Call (available for a few days) at 34:16 in the call, Microvision CEO, Alexander Tokman, in his closing remarks gave…
TI’s DLP® WVGA (848×480) and WXGA (1280×800) microdisplays use what are commonly known as “diamond” pixels. This article will explain what these pixels look like, their effect on image quality, and the reason behind diamond pixel. As a side note:…
I got asked a series of questions by reader “me_wwwing” after the article Laser with LCOS is Focus Free — Yes Really! that I am answering in this post because I thought they would be of general interest. I did have…
