Panel lottery frustration - Page 2

Just want to ask you guys, is there a 32" TN panel? coz I got a 32LE5300 thats has the "AUO" label at the back,.so it can either be a AMVA or a TN panel?? thanks

I stand corrected (as well as LG's consumer care center) re: the LED backlighting for this unit. It is edge-lit. Sorry for creating the confusion.

As for going to the store, the fly in the ointment on that is that the online retailers (based on the 3 stores that carry LG flat panels that I've been to) run about $100 less in asking price. Of course returns are a concern, but these days the major online retailers are honest brokers.

$100 is hard for me to bust anyone's balls about. I got a steal on mine purely because I'm an employee and it was an open box set. I paid retailer's cost not mine on it and it's a bit over the $100 you'd be saving. That being said every 26le5300 I've seen in my store have been W product code therefor IPS panel.

I searched through the LE5400 threads to make sure whatever TV I was buying had an IPS panel. It literally took 10 minutes in the store to realize I was getting what I want. The clues are more obvious than you think.

I bought an LG 32LD350 and I was curious what kind of panel it has.

The box says:

32LD350-UB.CUSWLHO so using the 'W' method this is an IPS panel. I looked at the TV with an otoscope, and the sub-pixels I see don't match any panel technology that Google Image Search knows about The sub-pixels look like these:



except rotate the above image 90 degrees - the sub pixels are horizontal instead of vertical like every image of sub-pixels I can find online. What does this mean? What kind of panel is this?

EDIT: I looked through the back cover of the TV and see the following:

LG Display
LC320WXE
(SC)(A8)

Apparently this is an H-IPS display, which explains the horizontal orientation of the sub-pixels that I noticed.

It's really worth the frustration, headache and gas mile to find the "W" IPS model. Been there and done that.

Hi. I have a 37LD450, and had a technician come in just today to replace the panel (to try to eliminate a low buzzing hum my set had). The original panel, and the new one just installed, was an AU Optronics and had the product code of "T370HW03", which is an AMVA panel. My TV's product code is "37LD450-UA.CCCDLH" for the record.

Personally, I'm happy with the picture I get with the AMVA panel, though I'll admit to not being a super demanding user (mine's used mostly for SD content, or 480p PS2 playing at best). No input lag that I can detect at all, though this might be a subjective thing. Only a slight image blur during fast scenes with lots of drab greys present for the most part. I'm happy.

I ordered this model from Adorama ($599 with free shipping) at the beginning of this month. The phone agent reassured me that the problems with the TF display were from the early days and that no non-IPS panel have been shipped in 4 months, but of course it was the non-IPS panel that arrived, and I refused delivery. Adorama deducted $39 from my refund. Be careful who you do business with.

Later: They refunded the "shipping charge" to my credit card.

Not all "W" designated LG tv's are S-IPS panels. You really need to look at the pixel pattern to determine that. I have a 47LD520 with a "W" in the product code but my pixel pattern is tiny squares, not the coveted chevron-shaped pixel pattern. The main difference between S-IPS and H-IPS is the pixel shape. There is also an E-IPS panel. It's possible that LG used the chevron-shaped pixel IPS panels in their 450 series and then haphazardly used them in other series. I have seen that pattern is the 520 series, though not my particular set. Makes no difference to me though cause I'm very satisfied with mine.

^truth. Bought a 42LD520 at BB yesterday, made sure it had a W, brought it home and uniformity was near perfect, but had some of the worst off angle washout I've seen. The one they had on display hardly washed out at all. I don't have a magnifying glass so I can't check the pixel shape, but there's no way an ips panel has this bad off angle viewing

All the people that bought the 32" LD450 on the bays'sdeal of the day, probably got panel return units.

Can someone post pictures of what the pixels should/shouldn't look like? I have no idea what a chevron is

bob

The chevron pattern is like this: >>>> as opposed to the pixel pattern posted a few posts back.

The more I read about these panels the more I'm convinced that "W" does indeed designate an IPS panel, but it could be any one of the 3 panel types. I looked at the 47LD520 on display in Fry's one day and it had a "W" in the product code. I could almost stand right next to it and the colors were nice and vibrant. Of course it was the floor model and there's no way I'm going to buy a floor model at Fry's. So I went to BB and they had 3 on sale in sealed boxes on the floor, all with "W"s in their product code. I got mine home and standing right next to it like I did with the floor model, the colors were washing out, much to my disappointment. However, that is an extreme viewing angle that we would never use so it wasn't a big deal. Sitting dead center and moving 5 feet either way doesn't change the PQ at all so we're happy.

Here are pics of various pixel matrix of various manufacturers.

Bring a 10x or 20x loop. Or a 50mm camera lens to use as a loop, to inspect sets.

I just went to Sears and this is what I found.

The LG 32LD450 on display was not an S-IPS panel.

The Panasonic U22 was an IPS-Alpha panel.

The Sony EX400s in 40" and 46" were both AuO MVA panels and not S-PVA.

The Samsung C630 and C650 were both S-PVA panels.

Awesome!

So, again, what type is the "good" LG IPS panel?

bob

From what I've been able to ascertain, S-IPS is what you want. Most, but not all, have the "W" in the product code and the chevron-shaped (>>>>) pixel pattern. You really need a good magnifying lens to determine the actual shape. I used an old magnifying lens the first time I checked my pixel pattern and they looked "squarish" which would indicate H-IPS, but upon closer inspection with a much better magnifying lens, the pixel pattern was indeed chevron shaped. I didn't think my viewing angle was what it should be but I actually calculated the angles and I was viewing at too extreme of an angle, much more extreme that I would normally be viewing the tv.

1998!:

S-IPS (Super-IPS, Hitachi in 1998)-Technology Developing the IPS technology with namalenono response time of pixels. S-IPS technology is widely used in the panels of a size of 20 and upwards. LG.Philips is one of the two major producers of S-IPS based panels. LG technology developed further, announcing TW-IPS (True Wide - IPS), which In addition to good quality and quick response time was achieved and a significant increase in visual angles S-IPS displays.
Overall, the IPS is designed for professional market segment where quality determines the purchase. Is also known variations in S-IPS (Super IPS) and DD-IPS (Dual Domain IPS), IPS-Pro In-Plane-Switching-Provectus / Provectus - means innovation in Latin /

I'm buying Samsung LN46C630 tomorrow, what exactly do I ask the person assisting me with the tv purchase to check in order for me to get the samsung panel instead of the cheaper models.

Anyone order an LG 37LD450 from Amazon recently? Want to know the likely hood of getting an S-IPS.

I gave up trying to get a straight answer from LG customer service about their panels. I bot a Panasonic TC-L42D2 instead. At least you know what you are getting.

I agree. There is no guarantee that buying a "deal" online is going to get you an S-IPS panel. Calling LG is useless because they don't have reliable information. LG was caught by surprise with this IPS panel fury. When they say that their panels are IPS, they don't say which kind of IPS panel they're using (e-IPS, S-IPS, H-IPS). So in a sense, they are telling the truth. I have seen a "W" LG that didn't have an S-IPS panel as determined by the "loupe test" (magnifying glass looking for the chevron-shaped pixels). This could have been a refurb, who knows? The "W" is pretty much a sure deal but as soon as you get it home, do the "loupe test" to satisfy yourself. There have been lots and lots of tvs returned because of this and other reasons. There may be absolutely nothing wrong with them but retailer can't sell it as new so some of these killer deals may just be returns or restock. The retailer should be upfront about this but as well as know, that's not always the case.

FYI, for the 2011 LK450 line (succeeding the LD450 line), you would want to get a "Y" designation for an S-IPS panel. I just picked up a 37LK450 and my product code was: 37LK450-UB.CUSYLH I also verified the panel using a 7x loupe looking for the bracket (chevron) pixel structure. I went into the store looking for a "W" in the product code, but all three boxes they had showed "Y" and with the TV being so new none of them were on display. So the salesman at BB was kind enough to pull one out of the box and turn the unit on for me to confirm without any obligation to buy. I then tried to haggle and pay "open box" price to no avail

dzasta, does your LK450 do 4:4:4 like the LD450?

I'd also appreciate updated findings re: the LG xxLK450 [didn't even realize LG was continuing the model-line into 2011], and I'm also curious as to whether the "Y" code will apply to S-IPS panels throughout the 2011-models involved in 'lotto'.
We've also heard nothing-much in AVS from 3xLV3500 owners -- I recently sent back an 37LV3500 "D"-lotto-loser to Amazon (refused delivery, unopened). These are basically 37LE5300's, but 60hZ [I'd hoped they would offer LED-contrast/'no-buzz' advantages over LD450's while exhibiting 4:4:4/price advantage over the 37LE5300]. Now, I wonder if the LV3500's will also find their way into the 2011-line (like the LD450's did), with "Y" replacing "W" for IPS?
Newegg/Buy.com/Amazon and many others must be well-sick of covering double-postage on reject-LG's due to lotto-lust (terrible thing, when consumers become product-savvy). I felt guilty re: Amazon, myself -- but I want what I'm paying for. Why LG risks alienating customers with these tactics is beyond me [as is their choice to disable features like usb>movie playback in LD-firmware, forcing xxLD450 and other owners to resort to Hacks to enable those functions].
I may go with a Panny IPS-Alpha as alternative, once deciding between an edge-lit/120hZ LED like the TC-L37E3 & a CCFL/60hZ like the TC-L37U3/U22. Which of those are best for PC/text while still offering 'pop' and PQ for movies/HDTV&SD?
And, are there other contenders in a 37" lcd [ignoring 3D/Net-features], re: PQ&PC-utility?

Someone reported earlier that they had the 32LK450 with the S-IPS panel and a "Y" in the product code, but it was unclear whether they had confirmed that with the loupe test (chevron-shaped pixels). I guess one could go to BB or any other B&M with a 10x magnifying glass and check out the pixel pattern on their demo LKs. Anyone looking for a weekend project

A number of people in the LK520/450-thread report the Y-replacing-W in LG/2011 sets (unsure how many confirmed via-chevron?). I wish I could get to a B&M within a hundred-miles to compare varied 37" LG's, but will have to shop online, after relying upon reviews/comparisons from calibrators of multiple-models [37LD/LK450's and similar, hopefully extrapolating for comparisons re: the 37LE5300&37LV3500 as LED 60/120hz equivalents]. I belive all offer the ISF calibration/menu options...?

They should offer the extended Expert settings (ISF) for calibrating. That being said, there are enough differences between the models (even in the same model line) that you may not be able to take a calibration from one set and successfully apply it to another. We discovered that in the LD thread when we were calibrating our sets.

Granted...others numbers are just a good-start for experimenting.
I meant I required comparisons from those few who have calibrated several of these similar sets to choose between them (all at similar price-point, but differing in 60-or-120 hz and CCFL-or-LED). I've no other basis for making a decision -- just a focused priority for PQ re: movies/HDTV/SD and 'puter-utility/text.
I need the angle-advantage of IPS, regardless other factors [but assume these sets offer more 'pop'/customization than similar 37's from Panasonic].

FWIW, My 47LD520 has the S-IPS panel. When my son wants to use his laptop (MBP) all he does is connect it via HDMI and the 47" LG is now a monitor with no distortion, lag phase, etc. It's not ideal having a cable across the floor but it works.

And yes, the posted settings for calibrations are a good starting point.
