Hey, I'm sorry gang. Did not mean to raise hackles.
In rereading my original post (and the thread title) I see it could make readers believe that I am not aware that Sharp itself is one of the biggest makers (OEM) of LCD panels. Quite the contrary, and I first listed the other major OEMs to show that I had done a little bit of work understanding the technology and who is offering what.
I just was unclear about what technique Sharp was (is) using in their panels (both in their own brand sets and what they OEM to other firms--specifically Toshiba as in another thread I am helping sort out whose panels Toshiba is using in various size premium 2008 models).
Thank you yatesd, for the link to Sharp's Kamayama factory. The one page where they diagram their "Advanced Super View" is the first I have seen that seems to indicate they are using in-plane switching. Nowhere else on Sharp's sites do they get anywhere close to indicating what method they use. Yet of course one can read technical discussions elsewhere (Wikipedia, etc.) on the pros/cons of the different LCD methods. but the actual mfrs. are not so forthcoming.
(I do know that it is easy to pick out a TN display by looking at it from below, but I did not rule out the possibility that TNs could be used by some makers as nobody watches TV from extreme low angles, and TN panels don't look too bad from side angles and they are faster than more advanced types--hence preferred by gamers, not that I am a gamer.)
Again, the intention of my post was just trying to clarify what type of panels Sharp is making in large sizes (apparently IPS types), as the premium pricing of IPS-based computer monitors (of all sizes) has me wondering how they can do so for giant TVs that cost less than 2K. So I thought perhaps they were making S-PVA or P-MVA units like the other majors.
So I guess this is settled. Thanks to all. Now If only I could find a list of what sizes each of the OEMs are making their large panels in, and which brands' models are using which. I wish there was a www.tftcentral.co.uk
(database for exact panel-type lookup for computer monitors) for TVs!
