Art.Lebedev say that have found a new OLED panel supplier for the Optimus Maximus keyboard. The new keys are a bit larger - 10.1 mm and 48x48 pixels resolution (instead of 32x32 px @ 0.9x0.9 mm).
Universal Display Corporation and Chi Mei EL Corporation (CMEL) announced that they have entered into an agreement for Universal Display to supply proprietary PHOLED⢠phosphorescent OLED materials and technology to CMEL for use in CMEL’s manufacture of commercial AMOLED display products.
Financial terms of the agreement have not been disclosed, however, as is customary with these agreements, Universal Display will recognize commercial chemical sales and license fee revenues from its supply of this material to CMEL. The term of the agreement runs through December 31, 2008.
CMEL is currently focused on producing small and medium-sized OLED panel applications.
Cambridge Display Technology (CDT) today announced that a new 20.8 inch, full-color, PLED monitor display demonstrated by Toshiba Matsushita Display Technology (TMD), at the 3rd International FPD Show in Japan, features CDT's light emitting polymer technology.
The super-thin display is based on TMD's LTPS technology coupled with CDT's light emitting polymer technology. The three (RGB) color-emitting layers use polymer organic electroluminescent materials, or PLEDs, and an ink-jet type printing process is used for deposition of each color.
MicroEmissive Displays (MED) has secured a loan facility worth £3.5 million from Noble Venture Finance for an equity stake which could amount to 5.3% of the firm's shares.
With this in place, as well as the placing last year, we have the wherewithal to get into volume manufacturing, says Graeme Walker, MED's chief financial officer.
Sipex Corporation today announced the latest addition to its family of white LED drivers for the portable market, the SP6415. The device features an inductive boost converter powering two independent drivers for driving the white LED main panel backlighting and powering the OLED sub-display or additional white LEDs. The device is offered in a space saving DFN-10 package.
Ideally suited for dual display architectures such as clamshell phones, the SP6415 can easily be configured to automatically turn off the sub-display when the phone is open. Each driver output current is programmed by a single external resistor. PWM dimming is possible via the enable pin which also is used to put the device into a 1uA showdown which greatly extends battery life.
With an output voltage up to 20V, as many as 5 LEDs in series can be powered at over 80% efficiency when the SP6415 is powered from a single cell lithium Li-Ion battery or internal 3.3V or 5V rails found in most hand-held equipment. When switching from powering the main display to the sub-display, voltage is adjusted to maximize efficiency and minimize power loss. Additionally, the device offers a full protection scheme against fault conditions such as: over voltage, over current, over temperature, and under voltage lock up.
The SP6415 is offered in a small lead-free DFN-10 RoHS compliant package meeting the extended temperature range: -40*deg*C to +85*deg*C. The device is priced at $1.40 each in quantities of a 1,000 units.
OTB Display today announced that it received an order from Universal Display Technology (Jilin) for in-line equipment for the manufacturing of full color OLED displays. The fully integrated OLED production system is based on solution-processed polymers and OTB's thin-film encapsulation technology, making it one of the world's first production lines that integrates the complete display cell manufacturing process.
Universal Display Technology (Jilin) Co., Ltd. acquired an OLED manufacturing turn-key solution including equipment, related services and process know-how. OTB Display will build up mass production capabilities at Universal Display Technology (Jilin) Co., Ltd manufacturing facility, which is located in the Changchun National High-Tech Industries Development Area in the Jilin Province of the People's Republic of China. The Universal Display Technology (Jilin) Co., Ltd. will commence mass production of OLED displays in 2008.
Sharp it has developed advanced LCD panels that would offer sharper moving images on portable devices such as mobile phones, pitting it against OLED displays. The new panels have a response speed three times as fast as its conventional panels and the world's highest contrast ratio for 2-inch LCDs used in mobile devices, Sharp said.
The Osaka-based company plans to make a sample shipment of the new liquid crystal display (LCD) panels by the end of the year for cellphones and aims for ¥100 billion ($836 million) in sales from the new products in the year ending March 2009.
Comparative OLED displays, which are also known for high-contrast ratios and high response speeds, could cost twice or three times as much as conventional LCD displays, it said.
Toshiba Corp. revealed that its mid-term strategy includes bullish plans to expand sales, expansion of NAND flash memory development and a commitment to OLED displays for TV applications.
"We've been developing OLED technology for small to mid-sized displays at the joint venture and we had expected that it would 2015 or 2016 before large-sized OLED technology for TV application would become available," Nishida said. "Now we think that we can develop the technology much earlier. We will be able to offer OLED TVs in 2009."
A recent story in the journal Advanced Materials, details advances in the use of organic light-emitting diodes (OLEDs) by Ghassan Jabbour and Jian Li, with help from graduate students Evan Williams and Kirsi Haavisto, a Fulbright scholar from Finland.
These researchers have developed an organic lighting device with 100 percent internal quantum efficiency by employing newly designed host materials coupled with optimized device architecture.
There is no waste of electricity, Jabbour says. All the current you are putting into the device is being used to produce light. It's the first time something like this has been demonstrated. Nobody else has shown a 100 percent internal quantum efficiency for lighting devices using a single molecular dopant to emit white light.
According to Digitimes, Sumitomo Chemical will invest 40M$ in an OLED production line in Japan, and will start to produce panels in 2008.
