OLED-Info is the web's leading resource on OLED TVs, displays and lighting.
OLED (or AMOLED) screens are efficient, clean, thin and bright, and are becoming popular in mobile devices. We bring you daily news and resources on this exciting new technology!
Recent OLED news:
Last week Samsung reported that they will soon reach 10 million Galaxy S4 sales, and yesterday (May 23) they announced that indeed they surpassed that number. It took samsung less than a month to do so. The company hopes to sell over 100 million GS4 units - or double the GS3 sales. The GS4 is currently available in more than 110 countries and will be rolled out to a total of 155 countries soon.
The GS4 features a 4.99" Full-HD (1920x1280, 441 PPI) Super AMOLED display, an Octacore 1.6Ghz Exynos CPU (some models use a Quadcore 1.9Ghaz Qualcomm CPU), 2GB of memory, 13 mp camera and a 2,600mAh battery - all this while being a smaller and lighter than the GS3. The GS4 includes a lot of new software features and special UI controls, include the Adapt Display which allows extensive display calibration adjustments.
Back in May 2012, 3M teamed up with Nanosys to commercialize QDEF Quantum Dot films for LCD displays. Today 3M announced that it is in the "final stages of scale-up" for these QDEF films. They plan to offer these to LCD makers that can be use them to make phones, tablets and TVs lighter, brighter, more energy efficient and with a larger color gamut.
In January 2013 Sony unveiled some new LED-backlit LCD TVs under the Triluminos brand, which use QDvision's quantum dot films. This TVs (and smaller sized LCDs in one of Sony's digital cameras) are already shipping.
Ignis Innovation announced that samples of its 20" 1296x768 (XGA) AMOLED display will be available in August 2013. Ignis will offer these samples to display makers for evaluation of Ignis' MaxLife compensation technology in their own displays (more on this below). They will sell the display for low volume, demanding applications such as medical imaging and scientific imaging.
The 20" AMOLED panels use a-Si backplane and are made by RiTdisplay. The panels are only 1.3mm thick (the complete display module is 3 mm thick). The refresh rate is 240Hz.
The Korea Times claims that Google's next gen Google Glass HMD (or "wearable computer") will use OLED microdisplays made by Samsung Display. Or at least SDC made a proposal for Google to replace the current LCoS panels by its OLED displays.
At SID 2013, SDC's CEO did mention OLED microdisplays on silicon during his keynote speech. He also says that these kinds of displays may be used for augmented-reality devices such as Google Glass. Last month Google's CEO Larry Page visited Samsung's OLED facilities, and apparently Page is "interested in Samsung's OLED business". So now the rumors are that Google are interested in small sized OLED displays.
eMagin officially announced their XGA OLED microdisplay for camera EVF (and other near-to-eye applications). The XGA096 OLED-XL is the company's smallest microdisplay ever (at 0.48" diagonal) and it features a 9.6 micro pixel design. it Actually has a resolution of 1036x780, or 12 extra rows and columns beyond XGA for optical alignment or extended image area. eMagin says they are already taking orders for samples of this new microdisplay.
We have heard a lot about this camera XGA EVF, and it's good to finally see a real product. During their latest conference call, eMagin reported that they missed their first EVF opportunity with a camera maker for an external EVF because they didn't have enough time to complete the module design. They hope to win the internal EVF contract and if so shipments wil begin in late 2013 or early 2014.
A couple of months ago Toshiba developed a unique transparent OLED lighting device structure that emits most of the light (over 95%) in only one direction. Now at SID 2013 the company unveiled more information about the new structure, calling these panels "Transmissive Single-sided OLEDs".
Regular transparent OLEDs use transparent electrodes (usually made from ITO) for both sides of the panel. When the OLED is turned on, it emits light in both directions. Sometimes this poses problems - if you want to embed such panels in windows, for example, you don't want light pollution on the outside which just wastes electricity. In addition, when such OLED panels are turned on they are no longer transparent.
