I believe all Panasonic LCDTVs utilize their IPS-Alpha Panels.

I myself have a latest version of Panasonic G10 LCDTV also utilizes IPS-a

Higher end LG LCDTVs and Mid and Lower end LCDTVs don't share same level panel.

thank you

yep, looks like IPS Alpha, i want one

I have a LG with super-IPS but i always compare it to my Dell 2209WA e-ips which I think has better overall color, the dell has same structure and shape as the Panasonic IPS Alpha

LG 37LH30 S-IPS



Dell 2209wa e-IPS (SMALL E)

there was a post on hardforum claiming the 2010 panasonic ips lcd had bad input lag but was testing done right and what methods were used to check

Coincidentally, I moved from a 2209WA to the 32U22. I haven't thoroughly measured or tested the U22 yet, but I had calibrated my 2209 with a friend's i1 Display 2 colorimeter so have a pretty good frame of reference. (For the record, the 2209 was pretty accurate from the factory.)

Comparing the two - with the exception of very oversaturated reds, I've found the colors of the U22 to appear very accurate (to my eye) when in Cinema mode. If the reds weren't so hot, I would be extremely happy with its out-of-the-box color representation.

My friend no longer has his i1, so I'm not sure what my next move is going to be. If I could tame the reds in the service menu somehow, I would probably go that route. If not, I'm almost tempted to return the TV since I do plan to use it for some (non-critical/hobbyist) photo editing.

Viewing angle is the same (great) between the two. Text rendering is almost perfect on the U22 with just a slight amount of shadowing on black/white transitions.

Do I spy the weighted companion cube behind there??? Awesome!

I checked out Panasonics web site. I've been saving for an LCD and have been going back and forth between LG and Samsung's offerings. However, the Panasonic 42" was also on my list, but they are hard to find except for floor models now.

Two important features for me are the ability to show pictures without a computer, and very good off-axis viewing. The 2009 42" Panasonic has this, and was at a pretty low price point, but when I viewed in stores, other sets seemed to be as good off-axis...

I also like how Panasonic is using matt screens - if they would only make their plasmas with matt glass! Oh well. Any idea on the MSRP for the 42" models?

How DARE you question my ignorance!?!

this might be the TV i'm looking for if it has over saturated reds

i find the LG has strong yellow presence, even after calibration to 6500k it looked off to me in comparison to my older Sony KDL 32L4000 which had stronger red tone.

I don't like 6500k, its supposed to emulate mid-day light but if i compare it to a blank white piece of paper the screen appears too yellow

I contacted Panasonic and they said the 42u25 does have the IPS Alpha panel, even though they don't list it on their site. I don't know about the response time, though.

I am really getting itchy for one of these new panels. It'll either be the 42u25 or a D2. I would expect similar lag times in both right? Right now its about a $550 difference between the two. Not sure if LED is that important to me if the u25 screen is likely going to be a really nice screen already. The black level differences could be a factor for me. But 99% of its use will be for pc\\gaming text crispness and lag are my two top factors.

take picture of tv and see for yourself

macro setting on your camera, get as close as you can to tv on white background (might have to zoom in even on macro) and see if you can find pattern that looks similar to what xact posted

Yes, this should be interesting. I contacted them over a week ago and they also told me its a IPS Alpha. I haven't got it yet, but i certainly want to know why they would say Alpha.

Can this be done with a magnifying glass? If so, what power does it need to be? Alternatively, how wide or tall is each red / green / blue pixel?

First of all

e-IPS is not E-IPS and vice versa.
e-IPS is not H-IPS and vice versa.
e-IPS most often seen in vertical layout with simple, stripped subpixel structure.
H-IPS most often seen in horizontal layout with complex subpixel structure.
small "e"-IPS is often referred to as economic version.
e-IPS is most often seen in computer monitors, "Officially" it is a simplified version of S-IPS. e-IPS main advantage is cost reduction.

This is same as the Samsung SPVA vs Samsung cPVA. The small "c"PVA is a simplified version of SPVA. This is also aiming at low cost market and on computer monitors.

Don't compare LG's vs other manufacturer's (for example: Hitachi IPS Panel maker) IPS panels as they are developed by each of their own, so they can be a bit different.
Old documents don't mean anything anymore since they are based on Hitachi and Panasonic. And the document itself is old.
Panasonic is the only one that is making the IPS-a Panel.
Their TVs which use IPS-a panels are often seen in 32" and 37" only, and for larger sizes you will most likely to be getting LG Display S-IPS.

For LG Display, there are four types of IPS
AS-IPS, S-IPS, H-IPS, e-IPS
the first three types are used in TVs and the last one is used in computer monitors.

However no matter how advanced or how improved a IPS panel goes. LG Display still calls them S-IPS.


(pic = AS-IPS, used in my LG LH95)


(pic = S-IPS, can be found in LG LH30, LG LH50...etc)


(pic = H-IPS, can be found in LG LH20)


(pic = e-IPS, can be found in computer monitors)

As you can tell from above
AS-IPS used in High-End LG TVs
S-IPS used in Mid-End LG TVs
H-IPS used in Low-End LG TVs
e-IPS used in Computer Monitors

So KakimotoRift,
You seem to be adding a lot to this thread. Thank you.

Can you answer two questions:
1. Which panel is the Panny U25?
2. Do you know which USA Panny models from 2009 and 2010 use which panels?

Thanks
