OLED HDTVs 40-inches and larger to be available in 2012

Many smaller electronic devices like high-end smartphones and PMPs are already coming with OLED screens. These screens consume less power than LCD counterparts making for longer run times. Another benefit is that an OLED panel tends to offer better colors than a comparable LCD.

LG has announced at the FPD International 2009 show in Yokohama City, Japan that it will be launching a new 15-inch OLED TV on the market by the end of 2009. The set reportedly will have a resolution of 1366 x 768 and a peak luminance of 450cd/m2. The panel will use a bottom emission type and is constructed of low-temperature polycrystal Si-TFTs crystallized by a high-temp process.

LG has plans beyond 15-inch OLED screens with 20-inch and larger panels coming in 2010, 30-inch and larger coming in 2011, and 40-inch and over panels in 2012. LG OLED marketing and sales VP Won Kim said, "Forty-inch and larger OLED panels will be fairly expensive in 2012, but they will be available in the market."

Consumers will have to wait until 2016 to see the price of OLED panels drop below the price of LCD panels. The reason is that a stable supply of large OLED panels at a low cost is unavailable today. Big challenges for OLED panels today include driver elements, organic EL materials, and the sealing process.

Kim said, "We will be able to use a low-temperature polycrystal silicon with the sixth-generation size glass substrate." He continued, "However, for 40-inch and larger panels, we have to use the eighth-generation size glass substrate. Therefore, we have to develop equipment that can deal with an SPC process at a temperature of more than 700°C."

According to LG, its OLED panels will use florescent materials until 2011 and then move to phosphorescent materials after 2012. When 2016 rolls around OLED panels will be 20-30% lower in material cost and have an equivalent yield to LCD panels today. In 2012, the OLED panel will have a 50% higher material cost and 30% lower yield than LCD panels.

Can anyone explain why "720p" TVs have a native resolution of 1366x768? Wouldn't you want the 1:1 pixel mapping with 1280x720?

1366x768 is more computer friendly, at least it was. 1280x720 is a more supported resolution than it was say 10 years ago.

The stupid part of that is why there still is overscan. TVs are now digital, not analog, and as such there is no ambiguous area that may or may not fill the tv screen anymore; you give us 1920x1080p, so why should it not map 1:1 perfectly?

It's the most ****ing annoying thing to watch 1080i on cable and have words at the bottom and sides slightly cut off for no good reason whatsoever.

But I think it has more to do with the tv than the broadcast because 1080i on my TV from the computer is also cut off, and only via nVidia's control panel can I make it not cut off in the screen. Perhaps once tv's are made to not work with analog signals period, overscan will disappear by default and not require a special setting.

There are even worse issues. Some DVDs are designed with the expectation of overscan. The extra information that is displayed if you disable overscan can be unintentionally shown. You can seem boom mics and things like pants on people who were supposed to be naked (Big Fish).

So, basically the best option is to give the user the ability to control the amount of overscan (from 0% overscan and up).

Of course, no manufacturer does that. =/

Overscan and curved screens are some of the worst parts of the CRT era. I had a tv once with overscan so bad that text windows in some of my SNES RPGs were getting cut off. It was really hard for content developers to account for it as all tvs were different. If you play FFVI in an emulator like bsnes today, you can see that the devs did not draw within 10px of the edge so that no one would have cut off text like they did in FFIV.

Hate to say this, but you know all of those gazillions of CRT analog TV's that were being used with overscan? They haven't been all thown away. They're still around with adapters on them (and in some countries probably still picking up analog broadcast). The CRTs still overscan.

But that said, that's not really the "problem" for many. Broadcast still assumes overscan. The broadcast world has not changed just because of the TV broadcast system -- and non-broadcast TV certainly has had no reason to change. As mentioned in the article linked to, when using a 1080P Plasma like we use (on direcTV no less), when watching SD feeds (they still do have those, not everybody is HD) many will visibly show on the screen digital data on the top of the screen. Data that is the closed captioning for the stream that is assumed non-visible due to overscan. Now, someday either purists like myself who want to keep the 1:1 pixel mapping and not overscan my HDTV will give up, or the systems that have been running for a zillion years with that closed captioning data (and some other things) will change such that it's not there (like on HD channels).

But for the time being, there still are overscanning crt TV's being used, and there are systems designed assuming the overscanning still being sent out to those tv's.

Have patience, the rest of the system will catch up. Eventually.

Besides, the only time you'll really notice that your screen isn't mapping pixels 1:1 is when using your PC because lines that are 1 pixel thick get blurred and text isn't anywhere as sharp.

Also, on a Samsung, to turn off overscan, look for the "Just Scan" picture option.

I think the reason behind the 15" 1366X768 is so they can sell it to the laptop manufacturers.

RE: Question
By abhaxus on 10/30/2009 6:44:38 PM , Rating: 2
I believe it has something to do with the RAM used for addressing each pixel. I read once that 1366x768 fills a 1 MB RAM buffer completely, giving the panel the opportunity to resolve about 5% more detail on a 1080p/i signal vs a 1280x720 panel 'for free' as far as RAM is concerned. No idea where I read that, so I can't cite it, sorry.

The sums add up. Assuming 8 bits (1 byte) per pixel:

1366*768=1049088 pixels
1049088/1024/1024 = 1MB

Except that 1 MiB if 1048576. 1366 x 768 is 512 more than 1 MiB. Since it's over, it's not free. If you use 1365 x 768, it fits, but 1366 x 768 does not.

that's probably why most TVs are actually 1360x768 or 1365x768.

Have they fixed the blue LEDS?

Last time I checked, in OLEDS the Blue LEDS still had a much shorter lifespan than the Green/Red ones. Has this been fixed?

I believe they still do, but it's more manageable now. Again, it's one more reason why OLED isn't plastered everywhere.

The Zune HD is probably the first major, large scale application of OLED screens. Hopefully, the investment into OLED tech will help develop the tech even more.

OLEDs have been used in small screen applications for a good while, but these are ones where the number of hours where they are active may be limited (where I've noticed them anyway), and in that car stereo application, having the blues get dimmer may not even be overly noticable.

Having a TV set that runs for only 10,000 hours before dying might be thought to be unacceptable, but if that's an auto radio display that may be considered quite a lot of driving time (and quite a few miles).

I have a Cowon S9 and owned it for about a year and the screen is holding up to it's factory state. Even though it's a PMP I love to leave the screen on because it's just that beautiful (AMOLED) even if it's just wallpaper.

I also just purchased a ZuneHD and I'm loving that as well and it has a bigger screen for better web browsing.

The funny thing is that Samsung supplies the AMOLED screens to these manufacturers which explains the similar if not same quality. The glass can be problematic though (it's for scratch protection) as it's not very good in sunlight.

I had a Creative Labs mini MP3 player with regular OLED and that was viewable outdoors but small.

I agree. I don't see the point of this "announcement". By 2016 there will be a new tech on the high-end that everyone will be salivating over. OLED will be common place likely.

Saying tech prices will be dropping is hardly any type of announcement or news.

The "announcements" are just forecasts, and like most forecasts they should be taken with a good measure of salt. Sometimes they are accurate, but it's been my observation that they're mostly not (unless it's say, for things within the next year -- and even then sometimes not).

Been waiting for OLED for a long time and just when you get impressed with OLED news and OLED doing 1,000,000 to 1 contrast ratios LCD kicks back 8,000,000 to 1 contrast ratios and available today. Its dynamic but LCD is resilient sucker that by 2016 LCD might still be in the fight. OLED cant seem to move fast enough.

Dynamic contrast is nothing but a marketing gimmick. It just changes the backlight level in response to the image, causing the brightness to fluctuate annoyingly.

One of the main benefits of OLED that it doesn't use a backlight at all, since the pixels make their own light, giving it a perfect black level. Finally, you'll be able to turn down the lights and still have black areas of the screen look really black, and not just gray.

You know by then there is going to be something better then OLED that you are going to have to wait for. :)

Check out the ZuneHD, Cowon S9 or Samsung Rogue to experience the black levels of AMOLED (Active Matrix). Sure it may consume more power than regular OLED but not much.

Consumers will have to wait until 2016 to see the price of OLED panels drop below the price of LCD panels

Does that mean cheaper than LCD prices now or LCD prices in 2016? If the later great, but if not then they still won't be competitive.

The "cost" will be lower. The actually price will be determined by supply/demand. My guess is with all the benefits of the OLED panels the sales prices will be above the (declining sales) LCD panels. This results in the manufacturer generating a ton of profit which is good because the need to invest a ton of money to get this ramped up.

Well, you have to think of a display technology that is better than OLED, then wait 10-20 years before it's actually mainstream. Might I remind you that LCD screens were used in some primitive ways back in the 80s (like the original Game Boy), and even the Game Boy Color had a color screen in 98, but I say it took 4-5 years (2002-2003) from that point to make that technology viable in a 32"+ LCD TV. And even then, I wouldn't say it was until last year that LCD TVs completely mopped the floor with ALL CRT technology in a store like walmart.

In fact, I'd say we haven't even hit the sweet spot of 32" LCD HDTVs being around $350-400. That's when prices will really drop to their lowest.

Now, if it took that long for LCD to hit mainstream, guess how long it'll take for OLED to reach that level.

I only know of one type of bottom emissions, and I don't think they can be used to make OLED screens...

OLED technology does not only apply to televisions. Cheap OLED will lead to Amazon Kindle V.25. A foldable, bendable piece of OLED. It will lead to better HUD systems in glass, airplanes, cars, hell, windows inside your home. OLED signs, media, posters, advertisements.

The possibilities of a flexible, low power visual medium are practically endless.
