When does the Edge Lit fetish end?

post #1 of 31
Thread Starter 
Took a trip out to Best Buy today to peruse 2010's "best" and I was sorely disappointed. Rows and rows of edge lit cr*p. Every talked-about 2010 set on these forums look pretty unremarkable and most clearly inferior to the CCFLs next to them in everything other than black levels. And even there it's mild at best. I have to blame this on edge-lit TVs.

Why did all of the manufacturers decide almost like a Kabal to introduce edge-lit and ONLY edge-lit displays primarily for this year? I am thinking it's some cost cutting measure along with energy savings, and some perception that thinness is in for 2010. All in all, it results in a cr*ppy image quality. Brightness on these sets appears lower than the CCFLs and sharpness and uniformity don't appear to be there.

So I have to say, ultimately, I am so damn stoked that I bought a Sharp 52XS1-US on a firesale last year for $1500. Because with RGB LED backlighting, it literally kicks the sh*t out of everything that's in the store now, and that's with the issues that it has. I was totally wondering if I had made the right decision to buy the XS1, but now that I know that ultimately everyone went edge-lit, I'm damn glad I did.

What practically all of the TVs you see labeled as "LED" in the store are for 2010. It's where the backlight is LED but only on the edges and not distributed over the entire back like CCFLs or LED backlit TVs.

You're kidding right? If not, LEDs are LEDs. Please tell me you've seen one. If not, WIkipedia is your friend.

Sorry, just that I own the other kind of TV on the market.

Well very, VERY basically: LCD panels require a backlight source. Basically a light source to illuminate them. For years and years, they used CCFL as that light source. You can think of CCFL as those old fluorescent tube lights you've seen at work, etc. Smaller versions of those. They were distributed in rows behind the LCD panel uniformly. Now LEDs are replacing the CCFLs as the light source for LCD panels. LEDs are preferable for a number of reasons. They provide a better quality and color accuracy of light, they use less power, they are less bulky than CCFLs, etc etc etc. But because LED backlights are relatively new, the manufaturers are going el-cheapo and only placing the LED backlights on the edges of the LCD panels instead of completely behind them. This results in arguably worse picture quality than even the CCFLs before them. Get it? Got it? good.

You think the picture quality would improve over the years with that crap. That is why I still like my plasma's.

The future is OLED which requires no backlight at all, and produces image quality superior to LCD, plasma, and everything else out there. It hasn't reached economies of scale yet, and won't for another 3-4 years, but it will be the only technology in the future and the far superior one. The only question about OLED is time frame. You already see it permeating the cell phone world, with the Samsung Galaxy S Android lines running Super Amoled, and getting rave reviews. So that's always the first start, it becomes economical in smaller displays and then progresses its way upwards. Happened that way with LCDs too. If you like plasma, and have one, it produces arguably the best home theater experience now anyway, so there's no reason for you to look elsewhere for 3-4 years. I just don't prefer plasma anymore, because I'm in super bright environments and need that "artificial" LCD brightness.

Here's hoping we don't have thinness/ edge-lit and 3D hanging over our heads like a Damocles in 2011. Perhaps they will focus on image quality.

I'm afraid consumers and manufacturers have already started down that path.

Aesthetics (super thin) and ack of consumer knowlege that LED =! better.

They make what people will pay for. Just like why cameras keep cramming more megapixels in instead of focusing on focusing on PQ.

good analogy with cameras... something I know alot about. Most consumers have no ideal about flash lighting, line bleed, banding, clouding... etc etc. Another camera analogy would be people on here are pixel peepers and measurebaters.

I have a 3 year old old Samsung LNT5271F. I always thought it was great but just now started to look into what was new on the market to upgrade. From everything I've read, the full array backlit is mindblowingly better than the edge lit but I still haven't gotten to see one yet. I wish I had started looking 6 months earlier because I would have gotten the Samsung 8500.

Every salesperson I've talked to from BB to high end locations like Modia insist that you really can't tell the difference but I highly doubt that from what I've read.

I was going to get the 65inch Samsung 8000 when it comes out but all these posts are making me hold off and hope someone eventually comes out with a good full array backlit in a large size. I read LG is revealing a nano led model this month at 400Hz, but it will likely cost more than a new car lol.

EDIT: And I agree about the stupid 3D craze. It's all being driven by Avatar. 3D is a fad that's come and gone for over half a century. It's unfortunate all the manufacturers are going down this path of "thin is in" and 3d. I'd take a foot thick TV and only 2D if it even had a slightly better PQ.

Find a Samsung A950 or 8500 and you won't have these issues. My a950 is magnificent and better than a Kuro

There appears to be only one place that still has some 8500's and they want $1000 above MSRP. Ever other place listed on the net that claims to have them really dont when you call. The salesman then tries to convince you that no one can tell the difference between edge lit and back lit.

Actually the ccfl from major brands like samsung and sony have better black level than thier led edge lit counterparts.

What's particularly damning to me is that most of these manufacturers HAD LED backlit lines the year prior. It's not that they hadn't even developed lines that they could have improved. Sharp had the LE720 series, Samsung had the 8500, Sony had the XBR8. It's as if they all decided at once to provide no competition and focus on the same segment. I highly suspect continued collusion in the LCD business. I mean we now know the extent of the collusion that existed with all of the recent legal news. Has anyone noticed a reduction in the price-reductions in the last year, combined with size stagnation? They are not developing or releasing the larger sizes, keeping the prices up on the smaller sizes, reducing costs with less material costs from using edge lit LEDs, and charging more.

^^It's probably a combination of a bigger profit margin for edge lit and that the vast majority of the buying public won't really know the difference. The new "shiney object" is 3D and thin.

I don't think there's any collusion. It's just that the huge majority of their customer base don't even know the difference between plasma and LCD, much less edge lit vs. back lit. They just want something that looks cool that you can hang on the wall to watch their soap operas and American Idol.

If a salesman tells 99.9% of customers: "This is a back lit LCD, not edge lit!" , they will just give them a blank stare and drool. If the salesman tells them "It's 3D!" they will squeel and say "OOOOOH! Avatar at the Imax!" (cha ching! Another sale is made)

Well to tell you the truth, I doubt your average TV buyer notices small PQ imperfections as much as you do. Let's face it, most TV buyers go by size and price and opposed to PQ. I am personally glad Sony decided to come out with edge lit LEDs, otherwise I wouldn't be able to purchase a 55inch TV under 31.5 inches in height that fits in my TV cabinet for a reasonable price. There are only two tv's out that are 31.5 inches tall (the limit of my furniture), and the LG lx9500 has horrible banding issues, so I'm glad I went with the hx800. I compared those two sets and to my eyes the Sony was superior, although I'll admit I don't have my TV in a theater setting, but neither does your average user. I've also heard good things about Vizio's offerings.

I think one of the main reasons for manufacturers going for LED is to do with the law that was/is going to be brought in in California, that determines the maximum power usage of all TVs sold there (it's very low).

I have seen similar LED/CCFL backlit models side by side in my own home and in store, and to me, brightness, sharpness and PQ look very similar. The look of the TV obviously plays a part in the buyers decision, but PQ is the overriding factor for many.
post #24 of 31
OLED will take the reins of true PQ and thinness and lightness and it's hold back is the longevity issues --- OLED life cycle is at less than half of CCFL and LED for now and one of the problematic colors has been blue I believe - they've had difficulty getting longevity close to existing panels.

Thus, one of the reasons they can place them on portable and shorter life span devices like Cell Phones and tablets where someone is unlikely to stay with a cell phone for ten years like they may with a TV - in most cases the small handheld device will be replaced long before it reaches it's half life issues or dies. Once they resolve this then that should be the next wave combined with 4Kx2K SuperHivision displays blowing away what we have today.

The 31" LG OLED at IFA looks pretty amazing but still too small for anywhere but my kitchen counter. I'm certain we'll see more OLED at CES to tease us with perfection.

As to the Sharp XS1, I had a chance a few months ago to get the 65" for about $3500 and passed it up for the Samsung 65" C8000 and now that damn thing is taking forever to get to market and the price is assinine since they raised the MSRP a grand to $5999 and challenging finding it discounted very much at all, typical early adopter price fixing like they tried with C9000 and now you can get them for 40%> discounts.

No matter how many times I compare a Sony EX500 CCFL 60" next to an EX700 LED I find the EX500 Superior and then how do you justify paying the equivalent of two EX500's for an LX900 60" except that you have built-in 3D. Obviously the best PQ value in Sony line and next to no side view washout like the edge lit.

+2 on the cameras. For most point/shoot all you need is about 3MP. Only when you get into the $200+ cameras is anything over 3MP really useful. A $100 10MP camera? You're kidding right?

Yep, and that's a good strategy for those with a limited budget. Buy a LARGE TV instead of a small one with slightly better PQ for the same money. That's why there is a LG60PK550 instead of a 40" LED set for the same $1,200 sitting in my living room. At a 15' viewing distance it was a slam dunk.

Like others, I felt that backlit (locally dimmed or not) was a better way to use LEDs, so I was disappointed when edge-lit suddenly became so common. But last Spring I needed a smaller TV for an upstairs room and got a good deal on an end-of-season B6000, an edge-lit model without LD. And 6 months later I'm quite surprised at how good it has been. The key was to get a good set of calibration settings, which I obtained on the relevant thread on this forum.

Yes, it has black uniformity issues, but only while I'm waiting for the PVR to boot up. Once there is something to watch, it's not a problem.

Edge-lit may not satisfy videophiles, but from what I've seen is perfectly up to the needs of most viewers watching broadcast signals.

It ends when they can do TVs as thin and cheap another way.

They only make TVs that are selling. Joe public doesnt know or care about LED backlighting they care that its big thin bright and cheap. Thats why theres almost no LED backlit or CCFL sets now and its all white LED with IOP not RGB LED.
post #29 of 31
Focus on edge lit rather than backlit is primarily a function of LED shortage which looks likely to be resolved in 4Q considering even 32" LED TV has inventory issues.

Come next year christmas probably the marketing engine will start to focus on backlit as LED prices collapses with MOCVD machines tripling this year and next.

I liken edge lit displays to reality TV. If people didn't watch it we wouldn't have a landslide of that useless crap on EVERY night. Supply and demand 101.
