Anyone, please

rachetino, please
check the rear panel sticker matrix code letter for both TV sets, for example for LG 19LH2000:
19LH2000 - "ZA.ARURLBU"
"R" - matrix type code letter, as follows:

R - LG Display Co.Ltd. TN
W - LG Display Co.Ltd. S-IPS / year 2010/
Y - LG Display Co.Ltd. S-IPS /year 2011/
U - LG Display Co.Ltd. IPS WUN SAB1/SAB2
P - LG Display Co.Ltd. IPS WXN SBA1/SBA2
Q - LG Display Co.Ltd. IPS WXN SAA1/SAA2
V - LG Display Co.Ltd. IPS WUD SBA1/SBA2
G - CHI MEI OPTOELECTRONICS CORP. TN
H - CHI MEI OPTOELECTRONICS CORP. S-MVA
J - CHI MEI OPTOELECTRONICS CORP. S-MVA
D - AU OPTRONICS CORP. AMVA
T - AU OPTRONICS CORP. AMVA

Thanks adtomov,

I checked rear panel sticker:
26LE5500-ZA.BEUWLJP (manufactured December 2010)
32LV2500-ZG.BEUYLJP (manufactured February 2012)
They were both assemled in Poland and have same type of matrix - S-IPS.
Picture in 26" model is really great, without complaints. But in 32" is less so great. Not so wide viewing angle with much contrast lost viewing from diagonal. And it seems that 26" model is much brighter just as it should be. Maybe it's because of less dynamic contrast - 3mil vs. 1mil in favor of 26LE5500.
All these reasons are why I would like to check panel model.

Anyway much thanks to all people running this forum and this thread, especially adtomov and hristoslav who help us to learn something new and useful.

hello guys
i just got my philips 40 inch 5507 model and i was looking at rear sticker on tv and i cant see any similar codes which someone posted on previous page for panels

So I was having a discussion with some of the staff in a Richer Sounds store today, and they had four 2012 LG 42-inch LS5600 TVs in stock. I got them to check the codes, and 3 of them had a 'D' meaning (assuming the above is still accurate for 2012 models) an Optronics TN panel, and one of them was 'W' - meaning they're using a 2010 IPS panel in a brand new TV??? Or have they gone back to 'W' for the 2012 ones now??

Was there a noticeable difference anyway (speed, clarity, etc) between the 'W' and 'Y' IPS panels?

Hi,

I bought Samsung UE32D6120 LED TV, type is 32P1UF3E (Chi Lin S-MVA, I think). How much this panel is worse than original and what impact does it have on picture quality? Viewing angle is good.

Thanks.

D - AU OPTRONICS CORP. - A-MVA
W - LG Display Co.Ltd. - AS-IPS

The difference between the 'W' and 'Y' is only in backlighting , difuzers and controllers.

Thanks.

By contrast, are almost identical, the difference is a better colour rendering of the S-MVA.

Thanks for the reply. Better colour rendering has S-MVA or the original (I think S-PVA)?

Ok thanks, so just to confirm that this means that the letters have slightly different meanings for 2012 models? (I thought the angle on the display 'D' unit seemed better than a TN could produce...)
Edit: Never mind about the 'D' code, just saw this.

Also, what specifically are these differences in the backlighting, difuzers and controllers - is 'W' better or worse than 'Y'? And will that make much real-world difference to the viewer, if any?

[herosrule]

so is there such a thing as an spva 2 panel? Ive been to panellook and found that Samsung make literally dozens of variations of spva panels.

lega, Philips 40PFL5507 has UV2A panel (Sharp).

withoutwings, 'D' meaning refers to an AUO AMVA panel, as hristoslav2 has replied. I've corrected my previous post.

[withoutwings]

Thanks to hristoslav2 and adtomov!

My final question is what exactly are the differences (to a viewer) between the 'W' or 'Y' LG IPS panels? Or is it mostly insignificant?

withoutwings, You know, I don't know exactly, but I wouldn't bet between two S-IPS matrices at all. Let me say that I am a high contrast LCD panel adherent, so my choice are PVA panels, of course. IPS based panels have best response time and good color reproduction. But they commonly suffer from high side angle black state light emission and relatively low front side contrast. Thus, IPS panel manufacturers still rely mainly on increasing white state light emission (transmittance) in order to improve contrast, which leads to ways above standard light emission at 100% IRE white state. Hope we'll see some significant improvements in the near future... The only partial exception are IPS-Pro (Alpha)- based panels (Panasonic, Hitachi), which have the best side view color reproduction (best viewing angle among all present types of LCD panels) for now.

The reason, I am replying that way, is that 99% of LCD TV users do not understand the main feature of a LCD matrix related to its proper color reproduction - its NATIVE contrast ratio. "NATIVE" contrast ratio is the ratio between the light emission at 100% IRE white state and 0%IRE white state (black state) at constant backlight emission (no backlight steering applied - dimming, dynamic backlight etc..). The upper limit of the 100% IRE white state, according to the standard, is near 30-40 ftL or 103 - 140 Cd/m2, so You understand, that the only proper way to increase contrast is not increasing white state light emission, but decreasing black state light emission (achieving deeper blacks of the panel ).

This is the main reason that plasma panels still exist - they have ability to produce much deeper blacks than LCD due to phosphor cells die-out during black state, combining with virtually no color reproduction viewing angle dependency.

The native contrast ratio of modern IPS panel gravitates around 1000/1 - 1200/1 and that of certain VA-based panels may reach 2100/1 - 2500/1. Both types of panels are being improved constantly.

Hope have been useful to all....

Thanks, that was very informative! I am aware of IPS' shortcomings, but having IPS on my phone and laptop displays already I have to say that I'm very much in love with the crisp clarity and colour reproduction. So I'm thinking I might just go in and pick up the one IPS TV that my local shop had in stock...

Hello can somebody tell me what kind of panel does Philips 42PFL3606H/58 has?

S-IPS panel.

[12none]

I recently purchased a Samsung UN50EH5300 (Version CH01) and would like to find out more about the panel in it. The service menu shows 50P6AF0D. Any help would be greatly appreciated. In particular I'd really like to know what the response time is and how this panel compares to S-PVA.

Greetings. Are we 100% sure that 46PFL5507 TV has Samsung panel? Shame, 40" model got a good rating from a review and my eyes on it.

[albani]

Hi Hristo

request tear-down some off panels such as;

Tosh WL/YL8xx series
Sony HX75x/85x series

as it seems that 2012 models has different type matrixes!!
as before those panels use S_PVA

note;according to your post#931 teardown pictures,have seen Sony Corp./Made in China

...and even worse it seems that there is difference in Sony HX855 between 40" and 46"...

One thing that is alarming me is that 40" is class B for electricity consumption, while the 46" is class A...
Could it be a signal of panel difference too?

Thanks in advance for your clarification, as always!

[dadash]

the electricity usage is definitely panel related, other hardware i.e. motherboard and graphic board energy consumption is insignificant in comparison...

I read the whole Thread and the info you guys provide here is awesome.

I came to conclusion my next 40" TV should have the new type PSA S-PVA Panel. I read the Samsung 46ES7000 is using this panel type. Can anybody confirm Samsung is using this panel in 40ES7000 as well?

[herosrule]

what is a PSA S-pva panel? is it a new type?

ether way ive got a tv with an s-pva panel and i can whole heartedly recomend both ips alpha or spva in anyones TV depending on your viewing style.

PSA (Polymer sustained alignment ), like UV2A is a method of in cell liquid crystals pre-alignment. This method achieves proper liquid crystal pre-tilt angles without rubbing, protrusions, or patterned common electrodes.
It can be applied in all types of VA matrices - MVA, PVA etc.
More info:
LCD manufacturing technologies target increasing transmission to reduce panel costs - ElectroIQ

[herosrule]

Ah I see, I actually found some papers on it in the end. So it's safe to assume that most va panels will be using in ether now or in the future as the goal is to reduce costs.

What is siting in Sony Bravia EX650 2012 models ?

[stefankostov]

I would like to ask hristoslav2 what kind and maker are the LCD-Matrices on:
UE32ES6300S, S/N: B4M93HLC500063, Vesion No 03 and
UE32ES6100, S/N: B4JQ3HDC300936N, Version No 01
Nobody in the shops and Samsung service in Plovdiv can give an answer.
Any suggestions which one to prefer.

Thanks: stefankostov

[stefankostov]

Hi,

Just now I saw some others are also familiar with Samsung.
That's why I repeat my questions to all: what kind and maker are the LCD-Matrices of the TVs below:
UE32ES6300S, S/N: B4M93HLC500063, Vesion No 03 and
UE32ES6100, S/N: B4JQ3HDC300936N, Version No 01
Do you have suggestions which one to prefer.

[herosrule]

I wonder if its worth posting a 2012 and 2011 LCD matrix by manufacturer up again as I bet nearly half of the posts on this topic are people asking the same question over and over again.
