Does the Toshiba C3030D have a S-PVA panel?

The reason being, I went into a Curry's digital, and examined most of the TV's panels and it appeared to have the characteristic << lcd. Incidentally Samsungs 32" R88 definitely didn't, bit 40" did.

If Toshiba use Chi Mei Optoelectronics panels, does this mean they could have a similar problem as the Samsung CMO panels?

Problem? What do you mean? Do you mean Samsung's panel lottery?

The thing is, my LG TV has an IPS panel, and that too has <<< pixels.

It was the 32" version. It would seem that a lot of these lcd's have the << panels then, damn it why is it so difficult to but a new TV?

Mr. Forum told me to take a few moments to ask a question, help provide a solution or just engage in a conversation with another member in any one of his forums.
So here it is: why should Toshiba use *VA panels when it made a joint-venture with Hitachi and Panasonic (IPS Alpha) to make S-IPS panels?

Toshiba have used AUO's and CMO's panels like Yannis said.
I have also posted it earlier: http://www.avforums.com/forums/showpost.php?p=3820347&postcount=15

Toshiba is also in partnership with Hitachi and Panasonic in IPS Alpha Technology, which manufactures IPS&#945; panels (using IPS-Pro technology).
Like I have posted earlier: http://www.avforums.com/forums/showpost.php?p=3775528&postcount=2


It's possible that it could also be LG.Philips LCD's S-IPS panel, because Toshiba is in collaboration with LG.Philips LCD's Poland panel plant (Toshiba owns 19.9 percent stake).
I have also posted it earlier: http://www.avforums.com/forums/showpost.php?p=3820431&postcount=16


But that plant just started it's operation at March 30, 2007
http://www.lgphilips-lcd.com/homeContain/jsp/eng/inv/inv101_j_e.jsp?BOARD_IDX=1239&languageSec=E

But it's possible that LG.Philips LCD have supplied panels to Toshiba even before.


So the panel could be AUO's A-MVA, IPS Alpha's IPS&#945; or LG.Philips S-IPS.

IPS Alpha only manufactures sizes 26", 32" and 37".

Toshiba is using CM and AUO panels for the simple reason that they are cheaper than IPS-Alpha (although not even close in performance).

If you go to German site and check specification of various models on some it says "IPS panel" (that may mean IPS-Alpha but most likely means LG/Philips S-IPS) , and in others "LCD panel Technology" meaning that CMO or AUO is used.

For example check these:

AUO's panels were based on P-MVA technology but they also launched AMVA panels last year which are considered almost as good as S-PVA.

CMO makes S-MVA panels but lately they have switched to VAextreme panel technology.

Yannis,

I have known this already.

P-MVA, A-MVA, MVA, S-MVA, VAextreme, PVA, S-PVA... they all are based to VA (Vertical Alignment) technology.

IPS (In-Plane Switching) is different technology.

Yannis,

Seems little strange, that Toshiba would use IPS panel for 37X3030D, but VA panel for 42X3030D.

It's very easy to identify the panels in the shops with-out looking at the pixels cos most are <<< shaped (inc ASV).

What you have to look for is purple/lilac effect when viewing black image from an odd angle.

S-IPS and Chi-Mei (MVA) are the worst but IPS-Alpha and ASV are very similar.


Next time I'm in Currys/Comet, I'll find-out what panel the Tosh C3030 has.

It&#180;s even easier: Just look at the back of the LCD. There will be a single letter next to the serial nummer, either a L, C or A.

L = LGPhilips
C = CMO
A = AU Optronics

Also the list JJK80 posted before is not 100&#37; correct. I&#180;ve seen some 37wl68 with AU Optronics panels for example.

My findings so far:

32c3000 L - LGPhilips
32c3001 L - LGPhilips
37wl68 A - AU Optronics
42wl66 L - LGPhilips
42wl67 C - CMO
42X3030 C - CMO
32W300P A - AU Optronics

Please feel free to complete the list :)

Thanks!

Then Toshiba uses similar marking method than Samsung.
