I think the necsel web site is a good source of info as it goes through the two techs that will offer laser tv one of which being DLP which is, as mentioned above, a Texas Instruments tech.
(So I would be guessing that Texas is one of the people making the light engines)
On the other hand is the light engine what Novalux make? I think it might be. Which means, if true, that ARR now own the chain as far as the light engine as a whole.
