I'm trying to understand the technical side to viewing angles on lcds. Why do some lcds have decent viewing angles and others have absolutely terrible ones?
A couple of people have commented on the Sharp led-lcd as having great off angle viewing- is this because of it's advanced led backlight?
Since Pioneer has gotten into lcds now and is improving them for the US launch, is it a filtering system that will truly give full viewing angles?
thanks
Because they use different LCD technologies (SPVA, IPS, etc). As far as I know, Pioneer does not make their own LCD panels, so I doubt it'll be any better than what you'd see on a high end Sharp.

Thanks, I appreciate the help.
I saw a couple interesting articles on different quality panels. Still seems that if all residual light can be blocked off, rich blacks can be had without led as a backlight.
D-Nice briefly mentioned that the US Kuro lcds will be much better than the European ones- and they aren't using ccfl to my knowledge.
Turning into a Pioneer fanboy day by day ;)

thanksI think that the technology makes some difference.
The Sharp LED set is what could be considered "cutting edge" at this point and very few people have seen it, so I can comment on the viewing angles from it. The only really advanced LED LCD I have seen up close is the Sony XBR8 and it has he best viewing angle that I have seen. I have no doubt that the Sharp will be better, but it is costly right now.
Do the Kuro LCDs use a LED backlight? I hadn't heard this.

Kuro's aren't using led backlight, but whatever they do to block off residual light from the screen is second to none. I'm assuming they're applying the technology they're using for 10G Kuros to the lcd line, but that's pure speculation on my part. We'll know in a month and a half.

Since the light generated by a plasma is coming from a Phosphor inside the pixel and an LCD has to pass light through the pixel, I am not sure what kind of tech that can be applied from one to the other.
when i saw the title and opening post for this thread --
Off angle lcd viewing
I'm trying to understand the technical side to viewing angles on lcds. Why do some lcds have decent viewing angles and others have absolutely terrible ones?
-- i had high hopes of getting some substantive replies and information, because all i've seen on the lcd forum threads amounts to conjecture and somewhat-educated and uneducated guesses, including mine. (i've been under the impression that it is the type of panel that [primarily] dictates the viewing angles, but googling hasn't helped me so far.)
so, if someone has some real information and some real links to those that do, i'd be grateful.
