IPS panels are popular for monitors where accuracy is important for things like photo editing. Samsung doesn't use IPS panels, but Panasonic and LG do. Samsung uses VA types, along with Sony and Toshiba. In order of contrast ratios for VA panels (lower number being better) it goes:
1. S-PVA
2. UV2A (U-MVA)
3. S-MVA
4. A-MVA
S-PVA is usually preferable, although it can have slower pixel response than some other panel types.
For the EH line, the 32", 40", and 46" inch come in S-PVA (Samsung), S-MVA, and A-MVA types - the latter two being made by Chei Mei and AUO. I know the 37 inch EH uses only AUO or Chei Mei panels as Samsung and Sony's joint S-PVA panel supplier, S-LCD, doesn't manufacture panels in that size. Same for the 39 inch UN39EH5003. Either the 50" or 55" also tends to use Chei Mei,can't remember which one...
If you can find a "Version" number that can help. It's usually a four digit code, on a sticker on the side of the TV.
Anything starting with Cxxx or Bxxx is Chei Mei. Hxxx is a Sharp panel. In the past, samsung has used SQxx, SSxx, and SXxx to label their own S-PVA panels. These were called version "S" panels, and are also sometimes indicated by a Large "S" to the right of the label. Version "A" panels, were made by AUO, and have the labels ACxx, AAxx, and BAxx.
Samsung currently seems to be using Txxx to label their own S-PVA panels. TS0x and TH0x have both been tested via the service menu and indicate Samsung panels.
>>>> So going off of labels Cxxx/Bxxx = Chei Mei, Axxx = AUO Optronics, Hxxx = Sharp, and Txxx = Samsung S-LCD.
Probably the best way to find out the panel is to get into the TV's service menu.
[ Note: Entering the service menu will reset the TV settings to factory default !! ]
To enter the service menu:
(TV in Standby Mode)
Mute, 1, 8, 2, Power (in rapid succession).
(Non-US versions, Press info-menu-mute-power)
Look under "Option" or "Type".
Search for your model's "inch number", and look at the letter immediately following the "inch number"
A:Samsung
H:Sharp
P:CMI (chimei)
R:AUO (au optronics)
So a UN40EH5000 with a samsung panel, would like this: 40A6AF0D
Exit with power off on remote.
1) Some reading on Service Menu information...
2)...and a bit more here
Here are some pics of Samsung labels, and the service menu:

The numbers I posted were about the input lag, which is unrelated to motion blur. Input lag is the time in between when the source is received and when it is actually displayed by the TV. My conclusion was that it averaged 16-33ms, which is equivalent to 1-2 frames. This is an acceptable level for gaming.
