AMOLED need more power at white background than LCD no Apple product in 2011 with OLED
We got the chance to interview Barry Young the managing director of the OLED-Association and we discussed the near future of OLED Displays, the truth about the power consumption from OLEDs and LCD Displays, and when we see the first Apple product with an OLED Display. And when we can expect the first Tablet-Pcs with Super-Amoled.
In 2011 LG,CMEL AUO start also the production of small/medium sized OLED panels. The last years the only company which produced OLED panels was Samsung Mobile Display with a market share of 98 percent.
In 2011 the companies are able to produce 68 million panels instead of 34 million in 2010, that means that all manufacturer can return to OLED instead of LCD.
Barry Young about the truth of the power consumption of OLEDs:
It always depend on the content, as example if the application has a white background like excel or word a AMOLED need 20 - 30 percent more power than an LCD. But if you run a video or you show some pictures OLEDs would use less power than an LCD. It always depend on the content.If you show a video AMOLED uses 15% of the power that an LCD would use.
The OLED material is improving 10-20 percent per year, so Barry Young expect in the next two year AMOLED will use less power than an LCD also at white background applications.
Barry Young gives also some insider infos when we see 7-9 inch OLED panels from Samsung mobile display for the tablet pc market.
The 7 inch OLED panels are realistic in end of 2011, because Samsung Mobile Display needs some time to ramp up the production of line of that size.
Also we discussed when Apple will use OLEDs in their products. Barry young think that the first product from Apple with an organic light emitting diode Display will be in 2012. Apple want to use OLEDs in the near future, for a few days Apple filed 3 patents for future products.

The prolific design hub Art Lebedev is out with another of its creation and design-wise it’s got a major Philips hangover! I’m talking about the Optogan LED Lamp. To quote the studios, “the lamp combines classic ideas with advancements in microelectronics.” Anyways, the lamp features a radiator encasing that is designed as a set of ridges, which help in dissipating heat. These energy saving bulbs come as 40 & 60 watts. Simply love their organic form!

To paraphrase William Gibson, the future of lighting is here, it's just not evenly distributed. Light-emitting diodes (LED) lightbulbs have been coming on the market in the past few years, but their quality varies greatly, from "almost perfect" to "horrible."
I had the opportunity to spend a few days with two LED lightbulbs from Qnuru, and I'd like to share my impressions with you.
Photo: Michael Graham Richard
The two LED bulbs that I tested are the Qnuru OPAL and the Qnuru TOPAZ. Here are their specs (OPAL on top, TOPAZ below):
Photo: Michael Graham Richard
Qnuru TOPAZ & OPAL Specifications
The Qnuru bulbs use LEDs made by Cree. The versions that I have are "cool white" (6000k temp), but they're also available in "warm white" (3000k). They use a standard E26 socket and use respectively 6.4 watts and 9.2 watts, and they're both rated as replacing 60W incandescents, though the bigger OPAL definitely produces more light and has a wider beam angle.
They have a 50,000+ hours lifetime, which compares very favorably to about 15,000 hours for compact fluorescent (CFLs) and 2,500 hours for incandescent bulbs. It makes more sense to pay extra for quality if you're going to be potentially keeping these lights around for decades. In fact, they come with a 3 year warranty, not something you'll find on any fluorescent!
And of course, because they are LEDs, they don't contain any mercury, and they are a lot less fragile than CFLs and incandescents.
The heatsinks around the base of the bulbs are not there because the bulbs become very hot. They really don't. It's just that LEDs are more sensitive to heat than the components of incandescents or CFLs, and so they are designed to keep heat build up to a minimum.
My LED Experience
My first impression of the Qnuru LEDs when I first got them out of their (stylish) boxes is that they feel very high quality. I was expecting light, plastic-y bulbs and instead I got heavy, solid ones. The OPAL is rather big compared to most lightbulbs, so if you're thinking of using it in a cramped space, make sure to check the dimensions in the spec sheet above, but the TOPAZ is about the same size as an incandescent, or maybe just a tad bigger.
After spending years with CFLs, it was great to have lights that turn on instantly. I've never really thought that modern CFLs were too slow, but when you compare them to a LED, they seem pretty unhurried.
The light quality is quite good, though not quite perfect (maybe there's a tiny bit of blue or pink in the white, but it's subtle enough that I find myself wondering if I'm making it up or if it's really there). The main thing to consider is what type of lights you're going to have; most of my apartment uses much warmer CFLs, like in the photo below:
Photo: Michael Graham Richard
This is what the CFL that I was using looks like. I didn't do any software white balance on that photo or on the one below.
Photo: Michael Graham Richard
And this is the Qnuru OPAL LED. It's such a big difference that when I'm moving between rooms, my brain's automatic color balance has to work overtime to keep up.
This won't be a problem if you make sure to match the color of your bulbs, something that I couldn't do because these are review units (don't take this color difference as a negative thing against the Qnurus! I'm just mentioning it here as a reminder to match colors).
Photo: Michael Graham Richard
Final Words on Qnuru LED Lightbulbs
After living for a few days with the Qnurus, I think that I could live with them indefinitely, which is probably the best endorsement for any product. Not all LED bulbs are good, but these ones are. They use even less power than the CFLs they replace, they provide good quality light, they turn on instantly, and they're sturdy. They do cost more, but they last so long that the "cost per year" is probably very low.
The only thing that I wish is that I could also try the 3000k models to see how good their light quality is, how well they blend in with CFLs of similar temps, etc. That's the only thing that is missing from this review. If I can get my hands on the warmer models, I'll update this review with info about them.
Pricing: The bigger OPAL is listed at $55.12 for the standard mode, and $61.60 for the dimmable one. The TOPAZ is $41.13 standard, and $44.10 dimmable.
Thanks to Qnuru for providing the review units.

Why Apple can not use OLEDs in the IPAD-2
There are rumors that the second generation iPad is expected to hit the market first quarter of 2011.
Now the first suppliers goes official, Coretronic will be the main supplier of the second generation iPads Back light units. That means that the iPad hit the market with a LCD Retina Display like the first Ipad from Apple.
Now we can tell you why:
If Apple want to introduce the IPAD-2 in the first quarter 2011, they need millions of OLED panels NOW.
But this is absolute impossible, because the company with 98 percent OLED market share Samsung Mobile Display can not deliver so much panels at this time. In mid 2011 Samsung Mobile Display boost the production with the factor 10 with a new 5.5 gen plant. Also LG-Display build some new OLED panel fabs. Samsung Mobile Display can mass produce only 2-4.2 inch AMOLED or Super-Amoled panels for smartphones (Galaxy-S, Nexus-S, Nokia, Htc etc.) The demand is very high so SMD can not handle all orders for the smartphone market at the moment. At the FPD-International Samsung Mobile Display showcase for the first time a 7 inch AMOLED for the tablet market. But this was only a prototype at the moment, we see this product ready in Q3 2011. So there is no company which can mass produce 7-11 inch panels at the moment. But this problem should be solved in the next few years because: Samsung and LG-Display to invest 17 billion dollars in AM-OLED until 2015

Aston Martin One-77 present by 750 O-LED lighting Panels
Aston Martin present there new car One-77 with unbelievable 750 overhead OLED lighting panels. It looks like that the panels are from Osram ORBEOS. But this is not confirmed!
At the hand over they dance their beams all over the car’s bodywork, tantalisingly revealing the stunning form like a beautiful, long-legged woman teasing up her skirt to reveal her lingerie. The OLED lighting panels play around more than a minute then they completely illuminate the very first customer-owned Aston Martin One-77.

Lamp made out of keyboard parts: qwerty-light
Nolan Herbut’s lamp design is made out of keyboards. He meticulously created the fixture by rearranging all of parts of keys that he found from unwanted keyboards and wrapping the whole thing up.
The light that comes from the lamp creates an interesting and ethereal effect. Does it make you want to create your own keyboard lamp? Probably not, but it’s definitely an good idea to do something with your old keyboards.
I’d like to see the effect if colorful LED lighting were used inside this lamp instead of a regular lightbulb. I’m sure that would be pretty funky.

Considering I've just polished off half a jar of jam, you could say I'm a fan of all things preserved. But inedible LED jams? JellyLamps' bright hues make me sad I can't slather a knife-full on a bit of crust.
When turned upside down, the LED light inside each jar of JellyLamps jam switches on, and glows neon. When flipped over, rightside-up, it looks just like a normal jar of jam—albeit, one that's made from fruit plucked from the bushes of Chernobyl.
Unfortunately they're very pricey for what they are. Each jar runs off two AAA batteries (which casts 50hrs of light, apparently), and costs 35 Euros (around $46). [JellyLamps via HolyCool via OhGizmo]

While it won't cast enough light to read by, Huey the chameleon lamp would make a great night-light. Like a true chameleon, he adapts to his environment and glows in the same color as whatever's underneath him.
If your whole house is void of color, he can otherwise cycle through the whole color range. A small squeeze of his body when he settles on your preferred color locks it in. Surprisingly, this lamp only costs $30, which I think is a great price for something that uses a couple of white LEDs and an optical sensor to recognize and emulate the color under his belly.

Are efficient LED bulbs worth the price?
At this point, LED bulbs are the hybrid cars of lighting. They're cheaper to operate but cost more upfront than their less-efficient cousins.
There have been LED spotlights and smaller lights for years, but now people can buy LED bulbs that give out as much light as a 60-watt incandescent and are designed for use just about anywhere. And rather than purchase them online or in a specialty store, they will be available at Home Depot, Lowes, and no doubt other familiar retail outlets next year.
Weighing cost and light quality, LEDs are worth considering right now for downlights and worth keeping an eye on if you have a lot of incandescent bulbs. If you already have a lot of CFLs in places like desktop lamps, don't expect a quick payback by switching over. But LEDs offer some other advantages, notably longer life.
Lighting your living space is obviously a very personal decision, but as you think about upgrading with energy efficiency in mind, here are a few factors to consider.
Cost
The good news on LEDs are that these lights, quality-wise, are quite good and they put out enough light for a lot of needs. But there's no getting around the fact that LED bulbs for general lighting are a new technology that comes with a price premium.
Home Depot's 800 lumen Philips LED bulb is priced at just under $40 and consumes 12 watts. A 40-watt equivalent from Lighting Sciences Group, which consumes less than 8 watts, costs just under $18.
If you were considering moving en masse to LEDs, you would need to take a long view from a financial perspective. Osram Sylvania figures that putting its $39.98 LED in to replace a 60-watt incandescent will save $132 over the life of the bulb, assuming a price of electricity at 10 cents per kilowatt-hour. That's more than 25,000 hours, or 17 years of using a bulb four hours a day.
The Sylvania LED designed for general lighting, which gives off as much light as a 60-watt incandescent and uses 12 watts.
(Credit: Osram Sylvania)
Taking a more conservative, short-term view, I did some back-of-the envelope calculations. If you used a bulb for just two hours a day and paid the national average of 11.5 cents per kilowatt hour, a single 12-watt LED will cost you about $1 per year. Comparable CFLs that consume about 14 watts come to $1.17 per year and about $5 a year for 60-watt incandescents in that scenario. (See formula.)
The minimal energy savings you get from going from CFL to LEDs reflects that LED bulbs are only slightly more efficient, when measured on lumens per watt. And, of course, CFLs have come way down in price over the past few years, while LEDs are still at the top of a projected downward cost curve. If you have incandescent bulbs, saving $4 a year with an LED is more compelling, but that's still a long pay back.
Electricity prices vary quite a bit (see here for your state average) in the U.S. and changing the number of hours per day will vary the result quite a bit. For example, if you use an LED bulb four hours a day and pay a higher rate of 16 cents per kilowatt hour, you'd save $11 per year per bulb over an incandescent, giving you a payback time frame for a $40 LED of between three and four years. Obviously, these savings get bigger, the more bulbs you replace.
More significant is that LEDs have a stated life time of 25,000 hours or more, compared to about 8,000 for CFLs, and less than 1,000 for incandescents. So if you factor in replacements, the numbers look more favorable.
Keep in mind that LEDs are on a faster efficiency and price-improvement track than other lighting technologies. Some lighting industry executives expect the price for an 800-lumen LED bulb to fall to about $20 within two years, which changes the math significantly. And utilities could begin to subsidize them, as they did with CFLs.
How you'll be using the bulb
Before you get too lost in the numbers, consider what you're using your lighting for. A good application for long-lasting LEDS is a tough-to-reach space or one where you need to leave the light on for a long time, for example. Often, CFLs are not always dimmable and LEDs typically are.
Also, consider that LEDs are best at directional light, which is why there are so many spotlight and downlight LEDs that fit into cans. Reviews for the Home Depot downlight from Cree--a 65-watt replacement that uses 10 watts--are generally positive and there are signs that pricing is going to be aggressive. They are listed at $49.97 online but they were on sale for $20, at least in some Massachusetts stores. Another good use is a goose-neck desk lamp, which is designed for directed light.
These latest general-use LED bulbs do a better job dispersing light, but there are limits. Last night I put two LED bulbs from Lighting Sciences Group into sconces that are at about at eye level on either side of a mirror. The amount of light was fine, but because most of the light was projected down, it didn't provide the light where I wanted it to use the mirror. That same bulb in a ceiling light works just fine.
Paying $20 or $40 for a bulb is obviously a lot compared to the $2 bulbs already available, but there are other reasons to switch bulbs besides yearly energy savings, as commenters at CNET and the Home Depot Web site made clear.
Many people get impatient waiting for CFLs to warm up, particularly outside, or they don't want to worry about mercury in CLFs (which should be recycled through waste collection agencies or retailers). The inefficiency of incandescent bulbs manifests itself as heat. Using cooler LEDs can be significant when you consider the cost of cooling.
I'm about to buy some LEDs for my own home and one feature I'm considering is color temperature. In some areas, I think that a warmer yellow light--rated at 2,700 Kelvin--would work well. But some LEDs have a cooler white at 3,000 Kelvin, which I'll put in other spots. I'll also be paying more attention to color rendering index, which is a measure of color accuracy.
Green factor
Some lighting manufacturers refer to the LED business right now as the "wild west," which doesn't sound very comforting as a consumer. The fact is that there are inflated claims regarding the life times and light quality of LEDs, which has even led to the Federal Trade Commissioner filing suit against a manufacturer.
As you're looking around, remember that for LEDs to last a long time, they need a heat sink. That's the main reason LED bulbs have metal fins that go down the side, making them look different than the classic Edison-style bulb.
One way to combat that problem is to check out reviews and buy from places where you know you can return the product. A good resource for learning the lingo around lighting and getting specifications on individual products is the Department of Energy's LightingFacts Web site, where you can see a new label now being used.
Another thing that lighting professionals will tell you is that we should expect more diversity in lighting technology, not a takeover of LEDs. In the next years, expect to hear quite a bit more about LEDs for the home as retail outlets start carrying more and prices come down. Also worth watching is whether they live up to their promised long life.
I bought a hybrid car because I wanted the best mileage I could get and, similarly, I plan on buying some LEDs to lower my electricity usage as my CFLs burn out. And like other consumers, I'll be watching for prices to fall and hoping they last as long as they should. How well they fare displacing other types of lighting remains to be seen, but LEDs are now part of the mix.

Samsung的Display技術越來越精進,臺廠要加油了
===============================================================
Samsung 發表接近大量生產階段的 4.5吋可折疊顯示器 並宣佈推出 7吋 Super AMOLED 屏幕
可折疊顯示器己經不是第一次出現在我們眼前,只是一直以來只聞樓梯聲,從未聽到將大量生產這回事。根據 Samsung Mobile Display 於 FPD International 2010 的講話,這枚4.5吋,擁有 480 X 800 解像度的可折疊 AMOLED 顯示器己經很接近大量生產階段,而 Samsung 這次放棄使用玻璃材質,改用新的塑膠材質,令可折疊的幅度更高。
與此同時,Samsung 也展示 7吋的 Super AMOLED 屏幕,並宣佈明年六月開始大量生產,屆時將提供予自家產品,並公開發放有關 super AMOLED 屏幕其他廠商。這款全新的 7吋 Super AMOLED 屏幕解像度達到 1200X600,較現時 Galaxy Tab 使用的 1024 X 600 TFT LCD 屏幕的解像度更高,看來 LG 也要努力一點,快點推出十吋的 IPS 屏幕予蘋果的 iPad 囉!

LEDs are, on small scales, the cheapest, most reliable, and most technologically powerful light sources out there. But their true potential is finally being unleashed. A new generation of LEDs can go anywhere - even into your body.
LEDs, or light-emitting diodes, are often used for text and video displays, and their infrared counterparts are everywhere in remote control technology. You can't take a trip without running into an LED - traffic signals are all LEDs, as are most of the lights on a car dashboard. And anyone who has been to a rock concert has probably run into a few people going crazy with LED-powered glowsticks.
Still, as researcher John Rogers of the University of Illinois points out, LEDs are brittle, meaning they can't be bent into different shapes. Well, no more, thanks to his new invention. He and his team have put tiny LEDs, each one smaller than the tip of a pen, on flexible electronic sheets. These sheets can be stretched and twisted up to 720 degrees without any loss in LED function, and they can hold up under soapy water or even underneath the skin, which they demonstrated by implant one sheet under the skin of mice.
As scientists tend to do, Rogers looks at this from the perspective of how it might benefit humanity. He sees great potential applications in using implanted LEDs for diagnostic purposes, and putting his LEDs on surgical gloves could allow doctors an even better view at what they're operating on.
But let's be real here - the crazy awesome applications of this invention way outstrip the humanity-benefiting ones. Implanted LEDs can be the new tattoo - put red ones down your spine for the sexy Cylon look!) Take your boring old household pets and stick some LEDs in them - instant excitement with glowing kitties and puppies! New glowsticks could be twisted 720 degrees to look like double helixes of DNA and handed out to biologists, giving scientific conferences a refreshingly heavy metal feel. And you just know somebody is figuring out how to put these things on a condom.
What crazy ideas do you have for these ultra-flexible LEDs? Here are some more awesome pictures of Rogers's LEDs in action to get your creative juices going.

The 45 LED Solar Spotlight Shines Bright
Bright, motion-triggered and solar energy powered – nothing could be greener than the 45 LED Solar Spotlight. By using not one, not two, but 45 wattage-friendly LED bulbs, this spotlight produces a brightness of 210 lumens produced whenever movements within an area between 3.05 m to 18.29 m are sensed after dusk. The spotlight also has a range of motion which enables it to light any area you wish to be illuminated and can be swiveled 180 degrees and can be tilted up to a 120 degree angle. Retailing at $69.95, the 45 LED Solar Spotlight comes with brackets and screws and most important of all, a solar panel with a 4.57 cable that allows it to be directed to where the sun is shining.

Samsung is planning to launch a display with an AMOLED plastic panel on the universal board within two years. Why? Because by switching to the plastic panel, the AMOLED display would become unbreakable.
Samsung's process in making the indestructible screen is to put a thin film transistor (TFT) on the plastic panel and to replace the vinyl protection sheet with polyimide film. Of course, if you drop your phone the glass will still break, but at least you'll have a working touchscreen underneath the shards.
Samsung plans to start producing these new AMOLED screens in two years. Let's hope they can figure out how to make AMOLED readable in the sun by then too. [OLED-display.net] |

近年來,LED隨著高輝度化的發展,整體市場規模獲得相當快速的成長,特別是白光LED的市場規模更是明顯的擴大,所以對白光LED新用途的開發也不間斷。為了擴大LED特別是白光LED的用途,如何提高發光的效率、相應的輝度、延長使用壽命,以及降低每單位照明的成本等條件。現在使用白光LED的發光效率,除了一部分的製品之外,大多都在30∼50lm/W左右。因此如果要代替白炙燈就需要將亮度提升到70∼80lm/W以上,如果要代替使用在汽車頭燈上的HID與家用照明的話,就更需要提高到100lm/W以上的發光效率。
在現有的發光效率下,如果需要一定程度高輝度,期望因為增加電流量來產生較大亮度的話,這就必須考量如何增加LED的面積來滿足所增加的電流,或者利用將數顆小型LED封裝在同一個模組之中,來實現封裝模組對電流量容許值的提高。但是因為在發光時,會出現熱效應比率提高的情況,因為如果投入的電流量提高,在目前的發光效率下,熱效應也會成比例的上升。另外,大面積LED比小面積LED的電阻來得要高,使得大面積LED本身的效應也比較大。如果單純以現有LED為基礎來提高輝度的話,將會陷入一個因LED本身價格,和散熱材料的成本過高而產生的惡性循環之中,這和以低成本化為基礎的市場特性是背道而馳的,而且熱效應量的上升會引起封裝材料的熱劣化,對其使用壽命也有很大的影響。 |

LED應用市場蓄勢待發
繼藍光LED(發光二極體)技術突破後,白光LED啟動了廣泛的應用風潮:從顯示、指示及手機光源,到液晶顯示電視背光源等。
LED商品化之路
LED誕生在1960年代,從紅光LED、綠光LED,一路開發到藍光LED,到1998年才真正看到商品化。LED具有省電、開關速度快等功能,目前LED大量應用在指示功能,而該領域也是LED最先進入的市場,如戶外顯示板、交通號誌燈及平面照明等。隨著高階手機採用LED當背光源後,LED又打開了新的應用領域。未來LED最被看好的應用,是在7-40吋的平面顯示器市場,一旦LED能成為平面顯示器的背光源,其市場產值將會大幅成長。
而白光LED取代傳統光源究竟何時會發生?工研院電光所光電半導體技術組朱慕道組長表示,LED若要普及到一般照明,仍有很長的路要走,原因是目前的價格仍太過昂貴。但若考量到整體使用壽命、省電效率及環保節能等要素,LED照明設備還有其應用價值。朱組長指出,過去採用傳統冷陰極燈管(Cold Cathode Fluorescent Lamp;CCFL)作為背光源的LCD TV,在播放足球賽,當球速很快時,畫面會出現殘影,且CCFL含汞較不環保。32吋的LCD TV需強調畫面,與傳統CRT(Cathode Ray Tube)比較,採LED當背光源,最大好處是可做到又薄、顏色又好。 |

專家:LED將迅速取代燈泡
科學家表示,技術和價格的改善將促使發光二極體(LED)在兩年內取代傳統的燈泡,大幅減少電力需求。
加州大學聖塔芭芭拉分校材料科學教授Steven Denbaars在上週舉行的SEMI NanoForum表示,目前,消費者和商家可買到的LED產品亮度,約等同60瓦燈泡。而LED的主要優勢為:壽命長達10萬小時,遠勝過傳統的白熱絲燈泡。
不幸的是,這類LED產品大約要價60?美元(網路上的價格不一)。但價格正以每年50%的速率下跌,因此不出兩年,同樣的LED應該只要20美元左右。DenBaars說:「在20美元價位,能源節省效應約一年即可兌現。」對於商店倉庫等長時間開燈的場所,投資效益相當可觀。使用1年後,LED的經濟效益將隨著成本持續降低而更加顯著。 |

不久前中央社發出報導說台灣打算在三年內將所有交通號誌改用LED, 經濟部能源局說目前全台有35萬個交通號誌使用LED,但仍有42萬個交通號誌仍使用傳統號誌燈,因此將在三年內花費2億2900萬元新台幣來全面更換,據估計這樣可以節省85%的能源消耗。同時也編列1億3000萬元在特別的路段改用LED-based的街燈。 |
