OLED TVs: Technology Advancements Thread - Page 54

Yes samsung galaxy S probably the most profitable smartphone now after iPhone. 5.5G is also versatile enough to make NB, monitor and up to 32" as per the LCD experience

Folks, does Mitsubishi make their own OLED???

(Source: SlashGear.)
Mitsubishi is planning on selling a 100-inch OLED TV later this month. Yes, that sounds jaw dropping at first, but sadly this isn't the HDTV that we're waiting for. In fact, it's not really HD at all.

This Diamond Vision model at 100-inches has pixels that measure around 3mm in size. Viewers will have to view the displays from at least a couple of meters away to get a decent image. The sets will get even bigger, perhaps to the 155-inch model that Mitsubishi prototyped. This massive size was accomplished by putting together multiple OLED modules, all of which add up to 17.6 pounds in weight and 15.1 inches think.

These Diamond Vision models have a maximum brightness of 1,200cd/m2, which is twice as bright as the company’s current LED-backlit LCD TVs.

The 100-inch model goes on sale later this month. Price has not been announced.

But you don't have to scale the image at all if you are only using the central 1600x1200 pixels on the monitor, leaving the others completely turned off (black vertical pillars on the left and right sides). In effect, the monitor is being used as a 1600x1200 4:3 monitor, the other pixels are ignored. So a 1600x1200 image being sent by the graphics card would be displayed at the "native" resolution of the central part of the screen, which is exactly 1600x1200, therefore there is no scaling going on, and therefore there are no scaling artifacts on the monitor when running a game at 1600x1200. Wouldn't that be correct? Do you fellows agree this is technically right?

In order not to scale your input resolution must be equal (this is optimal) or less than your display resolution. Most TVs and monitors max output is 1080 nowadays (unless u got a professional range) and not 1200

I'm talking about using the central 1600x1200 pixels of a 1920x1200 monitor. The other pixels on the left and right side are turned off, not used at all (either through the monitor's controls or through a setting in the graphics card's driver control panel). This would mean when you are playing a game at 1600x1200, you are playing at the native res of the portion of the screen that is in use, because you are only using 1600x1200 pixels on the screen, no scaling required at all.

According to Kaldskryke, this is possible to do.

Yes that's possible when u output 1200 from the graphics card. Sometimes u may need to configure the monitor

Hmm.....based on this chart, it looks like once Samsung gets to this Gen 5.5 process, then the chances that the next-gen Galaxy Tab would have an OLED screen will increase dramatically.......

Two cents

More signs of OLED not really gaining traction among manufacturers -- for TVs, of course:

TOKYO | Thu Sep 30, 2010 8:18pm EDT

TOKYO Oct 1 (Reuters) - Toshiba Corp (6502.T) plans to scrap plans to mass-produce organic electroluminescence (OLED) panels at its unit Toshiba Mobile Display and focus on high-demand LCD panels instead.

"The plan (for mass-production) is currently frozen. We'll review the production plan again from scratch," Toshiba Mobile Display spokesman Masahiro Kume said.

Toshiba Mobile Display, a joint venture between Toshiba and Panasonic Corp (6752.T), had invested some 16 billion yen ($191.6 million) in 2008 to install an OLED production line at its plant in Ishikawa Prefecture in northern Japan with plans to to churn out 1.5 million cell phone OLED panels a month, the Nikkei business daily said.

thankfully we have Samsung and LG. I can't wait to see the first 40-50" TOLED with either smart-glass or simple on/off LCD layer behind the panel.

From the looks of it, it appears that LG might be that company to go full force with OLED. That 30inch model they displayed is incredibly GORGEOUS. Still drool when I see it on the youtube video. Imagine in person.

Toshiba strikes me as a company that should put more focus on what they currently have and try to better it.

The last display Toshiba produced was CRT. They may have have aided the production of SED, but as all know, it was never commercialized. So I'm not surprised that Toshiba gave up. Then again, they could contract the panel from OEM as they do correctly and focus on other key areas.

PS: I wonder how other companies are progressing (especially with printable OLED). It can go directly in competition with low-end LCDs.

MBraun
Manufacturer Claims OLED Scaling Issue Solved; 42" Displays in 2011

HMMM :P

I expect LG to emerge the early leader in OLED HDTV displays. LG bought the Kodak white oled technology which should work out well. They can make an all white oled panel and use color filters (WRGB). There is no need to worry about color aging because white is so stable, and it'll probably be easier to manufacture (better yields).


I think it would be wiser for LG OLED displays to operate at 180hz (5.5ms hold time) rather than 120hz (8.3ms hold time). They are going to be sold at a higher cost, at least make the hold time lower than LCDs. It would be a stong selling point to combine with wide viewing angles and deep blacks.

Don't hold your breath for LG. Samsung makes >90% of AMOLED now and has plans for 5.5G ramp 3Q11. Haven't heard anything concrete from LG yet.

Think the main purpose of White OLED is for lighting and LCD backlight.

Correct me if I'm wrong but I read AMOLED can refresh at much higher rate than 240Hz. And I don't think they need hold time like LCD or is that inherent in the matrix structure?

I really believe the future is AMOLED with both TFT and plasma characteristics. LCD made Samsung major TV player but AMOLED gonna help it break away from the pack.

The future is TOLED with stacked RGB sub-pixels.

As for the matrix design, AM is hold-type by default. However, there are techniques that can help to eliminate hold time, which isn't possible on the LCD due to nonuniformed pixel response.

The LG white oled will last over 100,000 hours. There won't be color shift and should be easier to scale up to larger screen sizes.

A Samsung RGB OLED will have the concern of differential aging. Blue in paticular has a shorter lifetime.

I doubt Samsung will have large OLED TVs available at a lower cost than LG, but time will tell. Also LG deserves some credit for having a OLED TV available for sale today even if it is small.

Is AMOLED not pulse based like LED that u can switch on/off pixel by pixel? Who will commercialize TOLED first u think?


Not sure I understand this. U mean white OLED with color filter? Else how to produce RGB?

Obviously if you use white OLED, you will need to use color filters. I think his point is that you won't have differential aging of the three primaries (which currently is a very real problem with OLED longevity).

Honestly, I'm not really sure that a full white substrate is a huge win as it would require literally having 3x the pixel density, which is an awkward number. But who knows what they are planning? Nothing important is shipping in 2011 anyway.

AM addresses line by line using TFT substrate with a capacitor to hold charge. With PM, you can address pixel by pixel, but we haven't found a solution to eliminate cross-contamination, which was why we never say large PM-LCD or PM-OLED.

As for TOLED, both Samsung and LG have prototypes, which they have demonstrated (so do a few other reach institutes). TOLED has far more border application than standard OLED and it is much more appealing to consumer because when powered the down, the panel will be completely transparent. So large panels wouldn't dwarf the room.

TOLED can also be used in eyewear , providing immersive 3D experience with practical applications

TOLED also has medical application. To state one; it can be used help those with S.A.D (Seasonal affective disorder) by displaying various images on windows and patio doors fitted with TOLED.

It also consumes more power therefore reduces efficiency.

Yes hence from what I read White OLED is for backlight and lighting. I wouldn't hold my breath for THIS cost curve

Think TOLED also helps in addressing the blue OLED uneven aging.


The mitsubishi-pioneer 100" Diamond Vision OLED display is PMOLED with horrific resolution though

it is actually composed of 3" tiles

Does OLED have Image Retention?

Given that the lifespan of OLEDs is much shorter than, say, plasmas, it's actually fairly likely they are susceptible to permanent burn-in. In fact, this is almost certainly one of the many reasons they aren't being pushed right now, since they are both expensive and relatively short lived.

Yes it could be like local dimming on a per pixel level if they made the "backlight" an OLED pixel matrix.

The problem is that you still have the typical LCD issues (except bad black level) like poor response times, bad viewing angle etc.

An lcd with true per pixel backlighting and an advanced IPS panel would pretty much be the best flat panel on the market.

Response times would be an issue, but it's an issue that I've never really noticed on my lcds.

I doubt you would get per-pixel with white OLED backlighting but perhaps a significantly higher number of zones than LEDs.

Per pixel seems like there would be a lot of alignment issues and still very expensive.

why would you need a LCD layer when you just apply RGB color filter?

Thats why I think it will be used for maybe 2000 zone OLED backlit LCD first then white OLED displays when its cheaper.
