Samsung S, A, C Panel Differences: 2009 LCD Line-Up
(Other thread talking about the same issue: http://www.avsforum.com/avs-vb/showt...g+panel)<br />
I'm hoping to sum it up in this post/thread.-------Introduction--------
I've been trying to tell people about this 'panel' issue; but many people disacknowledge and disprove.
Truth be told; Last year, Samsung started using AMVA (AUO) and SMVA (CMO) panels, but only with the A630 model and down - A650 and up used strictly SPVA panels. This year, every set seems to involve more than one panel including sets higher than '630'. (Based on all 2009 CCFL-LCD Lineup)
Some do acknowledge about this issue to an extent; but believe there isn't ANY difference. Sorry, but there is a difference and people need to know about it.
I'm not trying to promote any other manufacturer and Samsung for that matter, nor am I trying to suggest not to buy Samsung. Just pointing out that reality is not always based on how we wished it would be.
All information gathered is either speculation and proof by codes, panel information, service manual, service menu, customer reference, and so on.
All information has been suggested as 'true', 'confirmed' and accepted. If you feel the need to deny, please refute instead.
Alright, so the question is, "Is there any truth to the difference in quality between these panels?" One word, "YES!"
Samsung has been recently doing some fishy marketing tricks by using several panels on their sets and on particular sizes. For instance, the 55" B650 (Which I own) all have CMO-SMVA panels; while the other sets (..40, 46..) using several panels.
It's not something to overlook!
1. We have the letters S,A, and C appearing on Samsung monitors and TV.
2. We have news releases of Samsung procuring panels from Chi Mei, AUO.
3. We have owners of monitors and TV complaining of performance issues.
4. We have pictures of various pixel geometries.
5. We have a picture of AU Optronics label through vents of a Samsung TV.
6. We have a Samsung Tech who won't deny it in the CNET forum.*
7. We have global reports of the same issues with Samsung product.
There has been no feasible alternative for the letters S, A, and C put forth other then the 3 panel makers. The panel differences have been noted in smaller computer monitors. *The Samsung tech would not be prohibited from commenting, as he says he is, if the theory was false.
---------------------------Here is a complete list of panels based on service manual collections (Thanks to Mikl1984)
Note: The list of part numbers (panels) is what your television should get.
In other words, the list displays the main panel
on that particular
model. Not all panels are listed because of lack of code numbers regarding
The service manual does not list all panels.
These case will be useful to find out:
1. Sticker info
2. Panel Codename in Service Menu
3. Pixel Photo

Samsung B750 Controversy (52" vs 40" and 46")
The Samsung B750 is Samsung's flagship top of the line CCFL-LCD. To
think that the top model should contain the best materials (let alone
Samsung component/panels) that Samsung has to offer, it surely is quite
surprising that they chose to do the panel lottery. We're quite certain that
all 52" B750 contain S-PVA panels. They use "LTF520HH01" and
"LTF520HE09". While the differences between the two are
unknown, the latter version are believed to be similar but with minor
differences. We may not notice anything at all between the two.
However, the more common sizes (40 and 46) appear to contain several
panels that include S, A, and C.
40" = "LTF400HG03" "LTF400HG01" and "V400H1"
46" = "LTF460HG01" and "T460HW03"

Like I posted above - there are ways to figuring out what kind of panel you have.
Usually you should be aiming to get the Samsung panel (SPVA), then AUO, and lastly the CMO panel - in terms of viewing angle performance.
1. *Sticker Info (Version #): http://i160.photobucket.com/albums/t...02-label-2.jpg
(Back panel sticker) http://farm1.static.flickr.com/245/5...09a460f5c6.jpg
2. **Panel Codename/Firmware: *No longer feasible*
3. Pixel Structure: http://i160.photobucket.com/albums/t...l-compare3.jpg
4. Internal Panel: http://www.avsforum.com/avs-vb/attac...8&d=1232646182
*The 'Version' on the sticker can indicate what panel you have (at least what panel that set should have)
Anything starting with the following letters on the Version is:
S = Samsung
A = AUO
C = CMO
At least this is how we add some definition to them;
Note: In these definitions, they only compile towards it's viewing angles
and NOT the actual picture performance as it will differ within the context of the panels
** (No longer feasible)Vendor
(A: AMLCD, D: CMO, L: AUO, I: CPT)-producerPanel frequency
(6:50 / 60Hz, 1:100 / 120Hz, 2:200 / 240Hz)-refresh ratePanel
(A: AG, T: TN U: UC)Resolution
(F: FHD, H: HD, U: UD)-resolutionPanel
1st/2nd (1st: 0, 2nd: 1 ...)BLU
(C: CCFL, L: LED, E: Edge LED)-type backlight
S-PVA, for example, is comprised of 2 sub-pixels each with 4 domains - so you effectively have 8 domains per pixel.
S-MVA (CMO) is similar.
A-MVA is actually somewhat more complex, but is also comprised of numerous domains per pixel.
S-PVA however will clearly have better color reproduction and off-angle viewing angles than the latter two MVA panels in regards to the comparison with the use of panels currently on the 2009 model line up. Picture quality can be discernible between S-PVA and *-MVA and it's ANSI contrast ratio is somewhat higher due to it's pixel formation and compatibility with Samsung's polarization; optical diffusion and lenses : http://www.hardforum.com/showpost.ph...5&postcount=10
To add contrary, it has been said MVA has it's capability to surpass PVA. AUO and CMO are two Taiwan companies who constantly improve MVA, that differences between PVA and MVA can be quite hard to discern. CMO has been mass producing large LCD panels for quite some time, as AUO just recently started. CMO technologies today are capable of producing picture quality surpassing PVA. However, it is up the supplied manufacturer to choose what type of panel should be used. Clearly Samsung did not choose to use the latest panel offerings from CMO and even AUO. In regards to the other information about CMO below and above, don't think negatively about CMO as they are an innovative company. It's just clear that Samsung decided to use an inferior AUO and CMO panel in their current line up.http://www.tftcentral.co.uk/articles...chnologies.htm
-> This site can be used for good reference, but keep in mind that some marketing fluff still appears in those descriptions.
Viewing angles on *VA panels is like are aguing about one being 5/10 and the other being 6/10 while IPS panels are 9/10.
But I have also see significant viewing angle variations on different samsung panels. A huge factor is personal tolerance to various issues. Also store conditions make it much harder to see issues (duh) so you can't compare what you see at home to what you see in store.
Bottom line is you can't rely on other peoples subjective opinions about panels. You have to see for yourself, ultimately you can't tell until you have it home. By then it may be too late. So it is a tough minefield to slog trying to get a good Home screen. But still more information never hurts. I want to know what I am buying. (guidryp) And so should you.http://www.youtube.com/watch?v=fy41W...eature=related

- S, A and C do represent the panels used as other posters have said and there seems little point in Samsung denying this any longer apart from to covering their backs.
They've covered themselves with this fine print: "The manufacturer reserves the right to make changes to product at any moment without notice.

Eg. In cases where S panel sets appear inferior part of the the issue could be the substitution of an A or C panel for an S.
Better watch out!
A lot of these Sammy panel differences can't be appreciated unless you compare them side by side. Unless you can decipher the difference. With high-end LCD's; consumers should expect to get hands on 'Samsung' panels rather than having a PANEL LOTTERY. Try comparing the different sets if you can and you'll have to agree with me
While there are constant variations from set-to-set; what else can be varied?
- Different panels should use different boards. So at least we know - Samsung does not produce AUO and CMO compatible boards to say the least.
- Some users of the (B650) reported that they had an LED lighting below the Samsung logo. While I do own this particular set, I have NO OPTION whatsoever regarding this LED indicator below the logo. Variation from set-to-set?
- Some say Samsung stopped improving their S-PVA panel (hence MVA is now comparable) but instead improves their UCP (Ultra Clear Panel) otherwise the optical components. http://techon.nikkeibp.co.jp/article...73651/fig8.jpg
- We do know that Samsung uses Chelsea (SDP83) & Arsenal (SDP84) video and audio chips. (Confirmed on the A650/A750)
Note: Well apparently they are using SiliconImage as a cost-effective measure to whatever sets. (We do know they use SiI9287 Port Processor)
Differences unknown but INFOLINK hacking has been useful to many Chelsea&Arsenal chip owners
At the very least here is a Sony's main board on their 32" (This is the only picture I can find) http://techon.nikkeibp.co.jp/article...73651/fig5.jpg
- Pricing; Because Samsung deploys mass outsourcing, is this a reason why their products aren't over-priced? I'm not sure but I'd pay more to get the best possible components (esp. from high-range CCFL-LCD series!)

---------------------------I'll look forward to adding more information on "S" and "A" panels from other users as I do not have them to test out.
CMO PANELS: RED SMEARING
I've come to realize that "C", the panel that I have on my B650 55", exhibits extreme amounts of red smearing when the picture displays both dark and light colored sources.
- Will update later and post pictures and video's -
Here are great video's that show the problem; thanks k1ng617.http://www.youtube.com/watch?v=-lF1Jz0o_7ghttp://www.youtube.com/watch?v=-Yr67Ndh66Y
Conclusion = Bad quality control. We consumers aren't stupid
It's up to you! I wish I could return my 55"B650 CMO television for a TV that has good quality control, or something with a PVA panel. But I was too late. So before anyone gets it fixed or anything in regard - be sure you get the best possible panel, possible! We shouldn't even be worrying of the purchase we made... but it's how it is. If you don't care, then simply ignore it!
Well hopefully you guys do understand!
