Is OLED TV Technology In Jeopardy?

MojoKid writes "Sony recently announced it would halt sales of its 11" OLED TV in Japan, where the panel first debuted. For now, the XEL-1 will remain on sale in the US and other markets, but Sony's decision to kill the unit in its home market and reduce the rate at which it's investing in future OLED TV development has been perceived in some corners as a judgment on the long-term feasibility of OLED technology. In the wake of Sony's announcement, far too many pundits have rushed to declare OLED panels dead, dying, moribund, or otherwise abandoned. However, it seems more likely at this juncture that we'll see development focus shift from large panel sizes to smaller ones, particularly since the smartphone/handheld OLED market is growing briskly and larger screens are inherently more prone to defects. Sadly, this means that your chance of traipsing home with a truly cutting-edge display before 2014 or so could be pretty minimal."

Jeopardy

At first I thought this article meant that OLEDs were actually the curved display panels in the Jeopardy TV show.

Stop confusing me, Slashdot.

No, it was a judgment in how stupid they were to come out with an ultra-premium-price 11" TV.

I understand that the Japanese are space-conscious, but 11" is a ridiculous size, especially in the day of 1080i broadcasts.

Sony came out with the 11" because that was the largest they could reasonably manufacture, but they forgot that it doesn't matter how cool the TV is if you can't see the damn thing. This one was so small, it'd practically have to be on your nightstand to watch it in bed. Maybe on your desk? Who wants to have an 11" TV on their desk when they have a 20" LCD display, or a 15" laptop display?

If they come out with an OLED set at a price that AV enthusiasts can afford at a size at least some people can use, they'll sell.

Don't forget the main problem, that the 11" TV cost like $2000. It was the first commercially available OLED TV, a limited production tech demo basically. As you say, 11" is really small, that's about the size of my laptops's screen and I can't imagine many scenarios where watching it from further than say a meter away is a good idea.

OLED seems to be making good progress for in smaller devices, it was only recently that only a few Kodak cameras and and tiny MP3 players had OLED screens, but now they're many of the new phones as well. It seems that we're moving up in size, so hopefully we'll see further increases in screen dimensions. The article even mentions the upcoming 15" LG TV, and although at around two grand it's still too expensive, at least we're getting there size wise. In any case, screw TVs - I want OLED computer monitors, which are luckily very usable even once you get to around 20".

Re:If so what instead?

[mangu]

a thin display without native rez, and CRT colour quality is still my dream, and they were promised what, 7 years ago now?

Don't worry, your flying car will have one on the instrument panel.

So

[ShooterNeo]

Let me get this straight : I hear that OLED is the "perfect" display tech.

+ Low energy consumption since all the light from the phosphers shines through
+ ultra high refresh rates possible
+ flicker free
+ full 180 degree viewing angle
+ perfect black levels with absolutely no light emmitting from pixels that are off
+ no ghosting at all
+ cheaper to manufacture than LCDs
+ flexible
+ ultra thin

Basically, a perfect display with no drawbacks other than the fact it isn't 3d like the holodeck.

Oh, and the blue pigments fade fast, so the display dims over time and the color balance gets messed up.

Oh, and it isn't being made in large enough quantities to be affordable.

So what's the deal? Why is Sony throwing in the towel now?

Re:So

[jtcampbell]

Active matrix OLED displays are actually really hard to manufacture compared to TFT LCDs.

A major issue comes from the fact that the TFT backplane has to supply an appreciable current to each pixel, rather than just a voltage as in LCDs. This means you can't get away with using amorphous silicon, you have to make the backplane out of Polycrystalline silicon which makes the whole production process a lot more complicated and also limits the size of panel that you can make.

Also, you generally you want to run the OLED elements in constant current mode, so you end up needing a current source circuit in each pixel. This increases the number of transistors you need per pixel from 1 or 2 in TFT to between 2 and 6 with OLED. And if any of them has a fault then you've got a dead pixel.

It was state of the art when it was announced, but the state of the art is always on the move. The reason XEV got pulled is that Sony has decided to spend it's money on RnD instead of fighting over razor thin margins in OLED production. Smart move considering the market conditions.

Make no mistake however, SONY is not surrendering the market, just making a tactical withdrawal. They will be back in a few years time with some new state of the art technology.

I would rather have dial gauges in my flying car, because any display capable of showing advertising eventually will.

Rumors of OLED's death are greatly exaggerated

[doctor_no]

This is being blown out of proportion.

The XEL-1 was discontinued in Japan because new TV sets sold this year will require a "V-chip" parental control, and a $2,000 11" TV doesn't justify a redesign to add that feature. The XEL-1 is still going to be sold in the US and Europe.

Also, Sony is still going ahead with their 22B yen ($210M) investment in OLED

Moreover, at the 2010 CES Sony just finished showing off a 24.5" OLED set that does 3D.

As Mark Twain said, can be applied to OLED, "rumors of my death are greatly exaggerated"

Re:There will be no more variable resolution displ

[fuzzyfuzzyfungus]

The sad thing isn't the hard native resolution of LCDs; but the fact that software hasn't caught up to that yet.

It is a real issue, particularly for older users or the visually impaired, that a 21inch CRT driven at 800x600, or some similarly low resolution will look pretty much fine, while a 20inch LCD panel will look like a blocky, badly scaled, mess. This is only because resolution independence isn't really Quite There Yet for most software. Sure, you can change the DPI settings; but that will break a host of legacy crap, and have no effect whatsoever on things like certain games that draw their own entirely custom interfaces.

Once the resolution independent vector-goodness finally filters down to the point of being actually usable in real world software setups, "native resolution" will no longer matter in the slightest, except as defining the upper bound for a given monitor.
