Sharp VA panels ? UV2A, Quattron...
« on: 30 December 2013, 03:59:07 PM »

On this page :
http://www.flatpanelshd.com/article.php?subaction=showfull&id=1368703754

It says on the lower end televisions they use : UV2A-panel
On higher end : Quattron panel (additional yellow stuff)

Now does UV2A-panel means this :
http://sharp-world.com/corporate/news/090916.html

So my question is : Are all panels used by Sharp VA type they call ASV [Advanced Super View] ?
Also see this : http://www.tftcentral.co.uk/articles/content/panel_technologies_content.htm#sharp_mva

How are viewing angles on Sharp versus the rest VA panels from other manufacturers ?

My understanding was that UV2A was an evolution of ASV.

I've never been hugely impressed with Sharp panels in terms of viewing angle or overall quality. Most problematic for me is the variable subpixel layout which I feel damages resolution.

Is the variable sub-pixel layout present on all models ( UV2A & Quattron ) ?

Keep an eye in 2014 and if you manage to review them see if it's still problematic.

How would you define this : variable sub-pixel layout ?

It's present on all recent Sharp panels, if I remember correctly.

We have plenty of 60" Sharp TVs at office building, and all of them use pretty strange layout where subpixels are slightly shifted in position in each row. It's like the single-pixel line is not horizontal, but instead show a little "zigzag" on the edge.
I'd say it slighly reduces perceived clarity and introduces "screen door" effect of some type.
More than that, there's nothing exceptional in terms of colours and contrast, either. Viewing angles are also typical for VA with some colour shift and blue-ish/violet blacks.

In other words it sucks big time. Thank you very much for the details.

My grandma's Philips LCD has something like this... Makes horizontal lines remind me of tiny zippers *-*-*-*-*-*-*- or so :P I hate it... But I don't think it bothers her ::)

I can't stand it. It damages resolution. I couldn't ever own a Sharp Elite for that reason.

LOL!!! And here I've been going around for what, two years, thinking "Ooooh, the ELITE, though... It might be an LED, but it must have been one hell of an LED, giving the PDP's such competition... :o... Well, except for that cyan thingy :chin: :lol:"

And you're telling me that it's pixels are all... Zippy? Well, now I know that it's definitely not worth the price! Might as well be a mid-range Philips LCD for I care, now :rofl:

I never cared much for the Elite LCD. I don't see much appeal in a display with color reproduction that off, even if the on-axis contrast performance was great.

UV2A is a MVA type panel
UV2A = MVA + PSA technology

Sharp make UV2A only from 60' and higher
50" and down is S-MVA from CM Innolux
