OLED-based Optimus Maximus Keyboard



Despite its innovative approach to keyboard design, the OLED-based Optimus Maximus keyboard is best considered an expensive novelty. Its $1,600 price tag keeps it out of the hands of the average consumer, and we also question the practical benefit of using 113 customizable OLED screens as an input device. There is something undoubtedly unique and appealing about the degree to which the Optimus Maximus gives you complete control over its keys' appearance. But even for gamers, designers, and others who tend to demand more from their input hardware, the Optimus Maximus offers insufficient utility to justify its high price.

The Optimus Maximus is a product of the Art. Lebedev Studio, a design firm in Russia. To purchase a board you can order directly from the Art. Lebedev store, or you can refer to one of five U.S.-based retailers listed on the Art. Lebedev Web site, of which ThinkGeek is perhaps the best known. Ordering from the Art. Lebedev Studio appears to be the most expensive option, presumably because your order will come from Russia directly, rather than through a U.S. distributor.

Physically, the Optimus Maximus is a bit clunkier than a standard keyboard. Its 6.75-inch depth and 1.25-inch height isn't that extraordinary, but at 21.25 inches wide, the Optimus Maximus is only one quarter of an inch less broad than Logitech's older G15 gaming keyboard, which is the widest modern keyboard we're aware of.

The Logitech board crams in 125 keys compared with the Optimus Maximus and its 113 keys. Considering that each key is in fact a small OLED display wrapped in a transparent plastic enclosure, it's perhaps easy to understand why the Optimus Maximus has a less efficient key density-to-width ratio. If the tiny screens were any smaller you'd lose visibility, and the plastic surrounding each display must be thick and durable enough to offer adequate protection. The keys are also removable, which makes for easy cleaning and replacement, but which also requires sturdy construction so that the connective parts hold up. The unfortunate side effect of such bulky keys is that the Optimus Maximus is terrible for touch-typing. The tightly packed keys make for lots of mistaken presses, and the mushy responsiveness slows down your words per minute.


Clunky plastic keys impede fast typing.

The hallmark of the Optimus Maximus is that its software lets you customize the image on each tiny display. The default layout provides a standard alphanumeric layout, but through the downloadable configuration software you can change the color, font, and size of the letters. You can alter the background color, you can type words, reassign commands, and even tie image and video files to display on individual keys, or across multiple keys.

Open up an image-editing program through the configurator and you can draw freehand over an image of the keyboard layout. Whatever you care to draw on top of that layout will appear on the keyboard as soon as you save your new file. You can assign different layouts to appear on the keyboard when you open a specific application or with a certain key command. The software also comes with media controls, Gmail notification, and CPU performance presets to assign out, among others.

As the Optimus Maximus works with both Windows PCs and Macs, it will recognize each operating system automatically and load up the familiar Windows icon and Apple command keys by default, depending on the system. The default settings reside on an included 512MB SD Card, and you'll find an SD Card slot on the back of the keyboard. This lets you save custom layouts and bring them with you if you move the Optimus Maximus between different computers.


The SD Card slot on the back lets you take your custom layouts on the road.

As technically impressive as these capabilities might be, it's hard for us to imagine who might truly need them. Gamers, Web developers, and professional digital image or video editors might seem like natural customers. However, given the level of familiarity most of those kinds of users tend to have with their computing hardware, it's the configurability rather than the visual reminder afforded by the Optimus Maximus's OLED keys that's most important. Much more affordable, mechanical keyboards from Logitech, Razer, and others offer similar customization flexibility through dedicated hot keys, macro programming, and even keys you can physically remove and rearrange in the case of the Razer Tarantula.

We can't say that the capability to alter your keys' appearance is a negative, and it's hard to deny that the Optimus Maximus has a very high novelty factor. Custom visuals on a keyboard are at worst harmless, and we can picture plenty of scenarios where they might be relatively useful, from teaching someone how to use a program, to switching between control schemes for different applications, to driving a home theater PC. The problem is that its $1,600 price tag is so far out of whack with the other keyboards on the market, that we simply don't find what the Optimus Maximus has to offer enough of a benefit to offset its cost.

Institutes join forces for oled production

organic led, oled, roll to roll production The Fraunhofer Institute for Photonic Microsystems (IPMS) and the Fraunhofer Institute for Electron Beam and Plasma Technology (FEP) have joined forces to develop process technology for roll to roll production of organic devices.
Fraunhofer has already established the Centre for Organic Materials and Electronic Devices Dresden (COMEDD) and the cooperation of the two Fraunhofer institutes is said to be a ‘significant milestone’ for COMEDD. The roll to roll equipment is located at the Fraunhofer FEP and used by both institutes.




“This plant is among the first types worldwide to develop and produce OLED (organic light-emitting diodes) lighting modules and organic solar cells,” said FEP director Professor Volker Kirchhoff. “This is an important step in the development of industrial scale manufacturing processes and the strategic cooperation enables a perfect combination of the competencies in the field of coating and device technology.”
Professor Karl Leo, director of Fraunhofer IPMS, added: “The new coating plant will enhance Dresden's standing as a cluster location for organic semiconductors and we should see the first oled demonstrators in early 2009.”

Sony ''awfully close'' to selling a 27-inch OLED TV




Sony is currently selling an 11 inch OLED TV (XEL-1) for about $2,500. This TV is more like an expensive executive desk decoration than a home entertainment product. Sony's COO Stan Glasgow said this week at a dinner event in San Francisco that Sony is "awfully close" to selling a 27" OLED TV.

What "awfully close" means in terms of time frames can only be guessed. I assume though that Sony will try to sell a 27 inch OLED TV this holiday shopping season, at least in Japan.

The biggest problem in producing OLED TVs lies in the amount of manual labor needed according to Sony. After the 27 inch OLED Sony plans to offer a 40 inch OLED TV.

E-paper and OLEDs

LG e-paper



E-paper can also bend like the newest OLED and LCD displays, but is much more energy efficient as it is a bistable (only uses power when changing the image) system that does not require a backlight. Readable in any light regular paper is, e-paper promises to create a new means of accessing information that will challenge traditional paper media. This e-paper display (EPD) from LG Display uses e-ink core tech and LG driver and backplane technology.

e-ink tablet development kit



Here's an e-paper electronic notepad development kit from E-Ink. That means there will be a bunch of devices with e-paper pads just around the corner. This kit contains everything an engineer needs to integrate a daylight-visible bistable rewritable electronic sketch pad into their designs.

UDC OLED




There must have been a rule at the show for every vendor to have at least one flexible (or at least bendy) display at their booth. This prototype media player with curved OLED display was a joint venture between Universal Display and LG Display. Due to their high brightness and contrast, OLED displays will dominate high-performance portable device applications. (That market niche is also very forgiving of OLED's aging issues, as a portable device's lifetime is significantly shorter than a traditional home display product.

As we pointed out, OLED's thin profile, high brightness, color saturation, and contrast make it a very good display for small-form-factor devices and interesting configurations. This OLED notepad concept piece from Samsung SDI had a lot of people drooling.

One of the issues of OLEDs is their sensitivity to oxygen and moisture, resulting in color shift as the phosphor degrades over time. One way to get around that is to use the OLED as backlight. A white OLED BLU-driven display will not have the color-shift issues of an RGB OLED, but still be extremely thin with excellent color saturation due to the higher quality of white light provided by the OLED. This prototype from Kodak uses an OLED BLU with advanced color filter technology.

Even though aging issues make larger OLED displays problematic, that doesn't mean that there aren't any large OLEDs around. This collection of 32-inch OLED displays from Samsung SDI shows that large OLEDs are not just one-off samples, but are truly on a commercialization process that will result in a finished product.

Sony CEO Stringer promises 27-inch OLED TV within the next year

According to CEO Howard Stringer, Sony plans to launch a much larger version of its impressive OLED (Organic Light Emitting Diode) television within the next year.

Sony launched its first OLED TV, an 11-inch model, in late 2007. The set, which also has the distinction of being the first commercial OLED TV in the world, won great acclaim thanks to the smoother, sharper and more richly colored images it offered over today's LCD (liquid crystal display) and PDP (plasma display panel) technologies.

At the same time Sony began showing a prototype 27-inch OLED screen and last month in Tokyo showed an OLED screen that was just 0.3 millimeters thick. Stringer, speaking at The Wall Street Journal's "D: All Things Digital" conference in Carlsbad, California, on Wednesday, introduced the thin prototype and talked about commercialization.

"This is 0.3 millimeters wide, it's a glass, we can produce this in plastic and you can wrap it around your arm, we're not quite sure why you would want to," Stringer told Walt Mossberg, a columnist for the newspaper and co-host of the event. "We're looking for applications for the next generation of the plastic version but this will come out in a 27-inch version fairly soon."

"Within the next 12 months, we haven't given a date," he said when asked to be more specific on timing.

The set would no doubt be released in Japan first, and be released much later in North America like it's younger brother, the 11-inch model.

Stringer didn't give much away when it came to pricing. The 11-inch model, which Sony calls the XEL-1, carries a relatively high price-tag of US$2,500.

"It's a complicated process and obviously we are working very hard to find out how to mass-produce it but until then it's very expensive," said Stringer.

Stringer's reference to a plastic OLED panel was to a prototype announced by the company in May 2007. Then it showed a small 2.5-inch OLED manufactured on a plastic substrate. The screen has a resolution of 160 pixels by 120 pixels and showed full-motion video while being bent and rolled.

Sony hasn't announced any sales targets for its OLED televisions but said earlier this month that it plans to sell 17 million LCD televisions in the fiscal year from April. That's a jump of about 7 million sets on the previous year. Sony hopes to achieve this by producing more models for the mid-market based on panels it will procure from Sharp. High-end sets will continue to feature panels produced by S-LCD, the LCD panel manufacturing joint venture it has with Samsung Electronics.

Samsung's new OLED laptop


Samsung's new OLED laptop shows a thin body and odd, buttonless half-sized keyboard.

The picture of the newest Samsung OLED laptop concept suggests Samsung may actually be prepared to fight for a triple-spike in sales.

The 12.1" laptop is an ultra-thin AMOLED from Samsung's display devision. The 12.1" screen measures in at 1280 x 768 with infinite contrast.

While the display is definately on the mark, the keyboard may not be. A touch-sensitive keyboard seems less than ideal, not to mention only being half size. Notice the flap on the back? My guess is you fold that over the monitor to protect the screen where the halfling keyboard cannot.

Samsung OLED Laptop Coming in 2009?

It looks like Samsung might be bringing OLED to laptops, and they look pretty darn cool. Engadget is reporting that consumers could see the AMOLED (active matrix organic light-emitting diode) concept as soon as 2009. Which consumers, is always a question—Japan? U.S.? Anyone? The 12.1-inch prototype offers a 1280 x 768 resolution and self-illuminating screen. Plans for the super-thin package include 14- and 15.4-inch models. Aside from an improved picture quality, it has a mystery panel around the back that’s quite the buzz on the web.
