The iRiver SPINN is rather new, but already iRiver are lowering the prices.The 4GB was sold for 250$, while the 8GB went for 290$.Now the 4GB is just 190$, and the 8GB version is at 229$.
As a reminder, the SPINN has a 3.2" AMOLED (480x372).
Powerlase Ltd. has announced the development of a 400G laser for green laser annealing (GLA) in AMOLED screen manufacture.
The laser products developed by Powerlase are designed in line with specific customer requirements. The 400G has been developed and tested in cooperation with one of the leading display screen manufacturers and is now entering the final development phase before being implemented in high volume manufacturing facilities.
Samsung is showing a window made from OLED Panels (12.1", 840x504 with 200cd/m2 luminance). The panels are 30% transmittive - which means they are transparent. You can see in the image to the right how it looks. From the back the window is almost (70%) transparent.
The OLED panel employs LTPS TFTs for the drive element. The device structure is a top emission type, and organic EL materials for RBG colors are separately applied by using a metal mask. Samsung declined to comment on the details of the technology that realized the high transmittance.
Samsung is showing a new OLED TV prototype that is 40" and is high defintion - 1,920 by 1,080. Samsung already showed a 40" OLED in 2005, but the resolution was not so high.
The new panel has a contrast of 1,000,000:1. Samsung doesn't say when they'll commercialize this - only that they don't have plans to do it now. They also said that the 40" is the largest size they can produce, currently.
Dainippon Screen DuPont jointly
established a new OLED manufacturing process based on the "multi-nozzle
printing method," which uses DuPont's soluble low-molecular-weight
organic EL material. And the companies employed this process for the
new manufacturing system.
The system has a monthly throughput of 10,000 panels per line (fourth generation).
Dainippon Screen plans to put the system on the market by the end of
fiscal 2009. They are now showing a 4.3" (480x272) AMOLED manufactured by the new process and machines.
Samsung has shown their new 4" Flexible AMOLED (480x272, contrast 100,000:1, 200cd/m2 luminence). It is very thin - 0.05mm in fact - that it 'flaps' in the wind (Samsung placed it near a fan...).
Samsung calls it the 'flapping display'. They claim they can actually make it thinner, but it's a bit difficult.
To achieve this thickness, Samsung etched an OLED panel that uses a normal glass substrate. The drive circuit was formed by LTPS TFTs. Also, low-molecular organic EL materials were employed.
The panel was not sealed by a glass substrate but by membrane sealing technology using a sputtering method. That's why the 0.05mm thickness is almost the thickness of the drive circuit board.
Researchers working in the European ROLLED project have developed a flexible OLED element that can be mass produced using roll-to-roll printing technology. The OLED elements can be used to add value to product packages. The new method is considerably cheaper than the traditional manufacturing method. The project was coordinated by VTT,and project participants included INM, CSEM, Ciba, Hansaprint, UPM and PolylC.
ROLLED project flexible element prototype
The OLED element developed under the ROLLED project is made from organic materials and is encapsulated in a moisture barrier film. The element is 200-250 micrometers thick, the equivalent to three or four sheets of paper.
Mitsubishi Digital Electronics
America, Inc. today announced the beginning of the laser era and the immediate
availability of the world's first, laser-powered television. The Mitsubishi
LaserVue(TM) 65" model is now being sold for
retailers nationwide. After months of anticipation, many consumers nationally
have already purchased LaserVue and have had the rare opportunity to
experience the amazing breadth and depth of color that laser television
offers. LaserVue has been introduced as the most energy efficient
large-format, high-definition television available on the market today.
LaserVue not only delivers two times the color of many of today's HDTVs,
but it also uses exponentially less power than LCD and plasma TVs.
LaserVue's technology is unparalleled; laser beams provide an extensive
range of rich, complex colors, along with truly distinct clarity and immersive
depth of field. Precise and focused, the purity of laser light far surpasses
current high-definition technologies. LaserVue has demonstrated a
reproduction of color gamut in excess of 200 percent of BT.709, delivering two
times the color of many of today's HDTVs. Brightness has been demonstrated at
approximately 500 nits. Additional features for LaserVue include Smooth
120Hz(TM), x.v. Color(TM) and 1080p with an Ultra Thin Frame.
A research group of the Dresden Technical University (together with Novaled) has achieved record energy consumption for OLEDs. The achievement brings the organic LED technology closer to industrial volume production, and these OLEDs are prototyped at the Fraunhofer ITMS.
The research team achieved an efficiency of 26, 22 and 3.1 percent for red, green and blue organic LEDs which combined form a white light source. The low efficiency for blue results of physical differences â while red and green OLEDs are phosphorescent light sources, their blue counterpart is a fluorescent one, resulting in lower light emission. The difference, however, can be compensated for by increasing the active size of the blue light emitter as well as sending a higher current through it, explained research group member Rico Meerheim.
TDK is showing a W-QVGA 3" PMOLED, using Dialog's SmartXtend driver, saying production may begin in the second half of 2009.
We covered Dialog's SmartXtend in February, and it's good to see TDK's implementation. The SmartXtend can reduce peak current through each diode by up to 30 percent compared to regular PMOLEDs, and it allows for greated resolution and larger displays than normal PMOLEDs, while being cheaper to make than AMOLEDs.
