Organic light-emitting diodes (OLEDs) are solid-state devices composed of thin films of organic molecules that create light with the application of electricity. OLEDs are a promising technology for flat panel displays. Compared to standard LCDs (including those with LED backlighting), OLED displays offer better contrast ratios (no trouble producing ‘true’ black’), require no backlighting at all, permit wider viewing angles, and don’t suffer from color shift. In short OLEDs can provide brighter, crisper displays on electronic devices and use less power than liquid crystal displays (LCDs) used today. In addition OLED diplays can be transparent, flexible, wearable, and theoretically printed by an inkjet printer (maybe not everything at the same time).
To display manufacturers, this new panel technology is expected to be the next big thing (in addition to 3D). Display manufacturers have been talking about OLED televisions and monitors as “a couple years away” for at least the last half-decade.
Unfortunately, it seems that everything hasn’t worked out too well for OLED. Sony Kills Next-Gen 11″ Display; Manufacturers Hedge on OLED TVs article tells that Sony announced it would halt sales of its 11″ XEL-1 OLED in Japan, where the panel first debuted. 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 online pundits have rushed to declare OLED panels dead, dying, moribund, or otherwise abandoned.
I think this case does not yer prove that. Sony OLED case was just proven that people currently don’t want to spend kilobucks on technology that’s not even ready from prime time because LCD LED and Plasma TVs are “good enough” for everyone. Sony XEL-1 is a sub-HD resolution small 11 inch (28 cm) television that cost thousands of dollars and looked pretty ugly, no wonder that it failed. If you are into electronics and want to see what electronics is inside that display, take a look at inside XEL-1 OLED TV display picture.
After this incident we’ll probably see development focus shift at least in short term from large panel sizes to smaller ones, particularly since the smartphone/handheld OLED market. OLED technology will evolve there and maybe some day it will be more ready for the prime time in larger displays. After smartphones the next step would be netbooks/notebook, then laptops and then computer monitors.

LG rolls out the ‘largest OLED TV’
http://www.theinquirer.net/inquirer/news/1602354/lg-rolls-largest-oled-tv
OLED (Organic Light Emitting Diode) displays are a hot technology soon to be seen on mobile phones and other devices requiring a screen, such as televisions and monitors. They are composed of thin films of organic molecules that create light when electricity is applied.
The 15-inch OLED TV seen above uses this technology to boast a high quality picture and has around a 3mm depth, which as you can imagine is very, very thin.
LG will also make 3D TVs in the LG6900, LX9900 and the LD950 models available in May. LG6900 and LX9900 are LED screens and use active-shutter glasses.

But, I seen your web log via Google. Do you actively promote your blog? I have going studying opening my own blog, but I am not secure if I could have enough people to read it to make it exemplary my while. Thanks in advanced for your feedback.

WORLD’S LARGEST OLED TV FROM LG OFFERS MORE REALISTIC COLORS, BRIGHTER PICTURE, FASTER SPEED

LG Unveils Much Anticipated 55-inch OLED TV for First Time at CES 2012
LG Electronics (LG) will present the future of TV technology at the Consumer Electronics Show (CES) in Las Vegas with the unveiling of the world’s largest OLED TV with a display size of 55 inches. By incorporating the company’s 4-Color Pixels and Color Refiner features with LG Display’s advanced OLED (organic light-emitting diode) panels, LG OLED TV generates the most natural colors of any TV set at a much lower price point than could have been achieved using the standard manufacturing process.
What sets LG’s TV picture apart from other OLED TVs is 4-Color Pixels and Color Refiner which work together to generate natural and accurate colors that are sharp and consistent. The 4-Color Pixels feature allows for more accurate color depiction by using a set of four colors (red, green blue and white) in comparison to the RGB setup used by other OLED TV manufacturers.

Sony quits organic-screen TV business
http://www.yomiuri.co.jp/dy/business/T120107003536.htm
Sony Corp. has discontinued production of TV sets with organic electroluminescence (EL) display panels, widely seen as the mainstream panel to be used in next-generation flat-screen TVs, it was learned Saturday.
Sony had been the nation’s only manufacturer of organic EL TVs
As a result, the company lagged behind South Korean rivals in terms of price competitiveness and enlarging sizes of organic TV products.
Sony discontinued domestic sales of the organic-screen TVs in 2010, but continued to export them to the United States and Europe.

Sony fights the OLED future with new ‘Crystal LED’ prototype
http://www.engadget.com/2012/01/09/sony-fights-the-oled-future-with-new-crystal-led-prototype/
While LG and Samsung trumpet their OLED prototypes, Sony has apparently moved on from the tech, choosing to highlight a new 55-inch Crystal LED prototype at CES 2012. Its display relies on “ultrafine” LEDs mounted to each RGB color, equivalent to the number of pixels, which is all affixed directly to the front of the display.

I have been surfing online more than 3 hours today, yet I never found any interesting article like yours. It’s pretty worth enough for me. In my view, if all webmasters and bloggers made good content as you did, the internet will be a lot more useful than ever before.

Nice post at OLED display is not dead Tomi Engdahl’s ePanorama blog. I was checking constantly this blog and I am impressed! Very helpful information specifically the last part
I care for such info a lot. I was seeking this certain information for a very long time. Thank you and good luck.

An interesting discussion is worth comment. There’s no doubt that that you should write more about this issue, it may not be a taboo subject but generally people don’t speak about these subjects. To the next! Kind regards!!

So, what is all the hype about ? LEDs (light emitting diodes) have been around for a long time. However, it hasn’t been until fairly recently that they have been advanced to the point they can now be used in higher power applications. Now they’re used in street lights traffic control lights, flashlights, automotive lights (brake lights etc.), and now in HDTV displays, just to name but a very few applications.
