New OLED architecture has 10,000 PPI resolution

Posted on by mixos

Researchers at Samsung in Korea and Stanford University in the US have developed and patented a new architecture for OLED displays with resolution up to 10,000 pixels per inch (PPI). by Nick Flaherty @ eenewsembedded.com

The design uses adapted an electrode ultra-thin solar panels with a base layer of reflective metal with nanoscale corrugations, called an optical metasurface.

The metasurface can manipulate the reflective properties of light and thereby allow the different colours to resonate in the pixels. These resonances are key to improving the light extraction from the OLEDs.

Compared to OLED displays in today smartphones with resolution of 500PPI, the metaphonic pixel array will be able to provide brighter and better colour accuracy for virtual reality displays.

“We’ve taken advantage of the fact that, on the nanoscale, light can flow around objects like water,” said Mark Brongersma, professor of materials science and engineering at Stanford who worked with Won-Jae Joo at the Samsung Advanced Institute of Technology (SAIT). “The field of nanoscale photonics keeps bringing new surprises and now we’re starting to impact real technologies. Our designs worked really well for solar cells and now we have a chance to impact next generation displays,” he said.

The metasonic OLED offers an alternative to the two types of OLED displays that are currently commercially available. Red-green-blue OLEDs have individual sub-pixels that each contain only one colour of emitter. These are fabricated by spraying each layer of materials through a fine metal mesh to control the composition of each pixel. They can only be produced on a small scale.

Larger devices such as TVs use white OLED displays where each of the sub-pixels contains a stack of all three emitters and then relies on filters to determine the final sub-pixel colour. This is easier to fabricate but are more power-hungry as the filters reduce the overall output of light.

In conventional RGB-OLEDs, the different frequencies mean red sub-pixels have a different height from the blue emitters. This means materials deposited above the emitters have to be laid down in unequal thicknesses to create a flat screen. By contrast, the base layer corrugations in the metasonic OLEDs allow each pixel to be the same height for a simpler manufacturing process.

In lab tests, the researchers successfully produced miniature proof-of-concept pixels. Compared with colour-filtered white-OLEDs, the pixels had a higher colour purity and twice the luminescence as well as pixel density of 10,000 per inch.

The next steps for integrating this work into a full-size display is being pursued by Samsung.

New Study shows Rare form of Magnetic and Electrical Property in stack-twisted Graphene

Posted on by Rik

A group of scientists at Columbia University and the University of Washington has found unique electronic states along with an uncommon kind of magnetism, can develop in a three-layer graphene structure.

The work was inspired by current research studies of twisted monolayers or twisted bilayers of graphene, making up either 2 or 4 overall sheets. These results were discovered to treat a range of uncommon electronic states driven by strong interactions between electrons.

We wondered what would happen if we combined graphene monolayers and bilayers into a twisted three-layer system,

stated Cory Dean, a teacher of physics at Columbia University and among the paper’s senior authors.

We found that varying the number of graphene layers endows these composite materials with some exciting new properties that had not been seen before.

In addition to Dean, Assistant Professor Matthew Yankowitz and Professor Xiaodong Xu, both in the departments of physics and product science and engineering at the University of Washington, are senior authors on the work. Columbia college student Shaowen Chen, and University of Washington college student Minhao He is the paper’s co-lead authors.

Graphene layers stacked and twisted

To conduct the experiment, the scientists stacked a monolayer sheet of graphene onto a bilayer sheet and twisted them by about 1 degree. At temperature levels a couple of degrees over, the group observed a range of insulating states and which do not carry out electrical energy, but they are driven by strong interactions between electrons. They also discovered that these states can be managed by using an electrical field throughout the graphene sheets.

We learned that the direction of an applied electric field matters a lot,

stated Yankowitz, who is likewise a previous postdoctoral scientist in Dean’s group.

On the other hand, when the scientists pointed the electrical field towards the monolayer graphene sheet, the system looked like twisted bilayer graphene. But when they put the direction of the electrical field towards the bilayer graphene sheet, it resembled twisted double bilayer graphene—the four-layer structure.

Besides, the group found completely new magnetic statesin the twisted system. Unlike standard magnets, which are driven by a quantum mechanical residential or commercial property of electrons called “spin“. As they observed, a collective twisting movement of the electrons in the group’s three-layer structure carries the magnetism.

“This is really just the beginning,” as stated Yankowitz, because they are dealing with the experiments to improve and understand the basic properties of the brand-new states they found in this research.

More information can be found in this research paper.

New WL-SMTW Series LEDs Emit Light of Wavelengths 450, 660 and 730 nm

Posted on by mixos

SMT mountable LEDs in a 2835 package extend Würth Elektronik extensive range of horticulture LEDs. The three WL-SMTW series LEDs emit light of the wavelengths 450 nm (Deep Blue), 660 nm (Hyper Red) and 730 nm (Far Red) – ideal for applications controlling plant growth through specific light mixtures. Besides vertical farming and lighting in greenhouses, thanks to their efficiency, small size and minimal heat generation the WL-SMTWs, combined with the manufacturer’s other LEDs are also suitable for classic LED applications like displays and backlighting.

A photosynthetic photon flux of up to 0.94 µmol/s at a current of just 150 mA, and the small size (2.8 x 3.5 x 0.8 mm) mean you don’t even need three mid-power LEDs to replace a high-power LED. This allows larger-scale and more homogeneous lighting applications to be realized. With its Development Kit, Würth Elektronik is there for the developers of horticultural lighting solutions, to whom the WL-SMTW product is particularly directed. In the REDEXPERT online simulation platform there is a “Horticulator” in which lighting recipes can be created (https://redexpert.we-online.com/redexpert/#/smodule/26). All Würth Elektronik LEDs are available from stock. Free LED samples are provided.

Cooperation with research institutions

“Our new LED series offers excellent value for money and high luminosity – the Deep Blue LED is unique on the market in this respect,”

Harun Özgür, Division Manager, Optoelectronics at Würth Elektronik eiSos GmbH & Co. KG expresses his satisfaction about the new addition to horticulture LED range (http://www.we-online.com/leditgrow).

Johann Waldherr, agricultural scientist in Würth Elektronik’s LED team, explains: “The blue light plays a role in many plant processes, such as the formation of secondary metabolites. The illumination with spectra individually created from the different wavelengths of monochromatic LEDs becomes even more efficient with the new mid-power LEDs, yet at the same time more homogeneous.

These three LEDs form a basic framework in combination with other LEDs of the WL-SMTW, WL-SWTP and WL-SMDC series, so it is possible to create specific lighting recipes for a wide range of the horticulturist’s quality parameters, such as more blossoms, more fruit, more biomass, more vitamins, and so on. As our partners’ innovation partner, we conduct intensive research and we have established a competence network with research institutions, sharing our knowledge with our customers.

For example, Würth Elektronik maintains research cooperations with the Dürnast Greenhouse Laboratory Center at the Technical University of Munich along with other research institutions.

PICKitPlus now runs on Linux – The software that uses the Microchip PK2 and PK3 to program new and legacy microcontrollers from Microchip.

Posted on by mixos

We are very pleased to announce the release of the Linux version of PKCMD: PKCMD-LX.  This is the Personal Computer version, designed to run on flavours of Linux, both 32 and 64 bit.  This was a huge investment by us. But, these are exciting developments for the software as it shows what can be with the PK2 and PK3 programmers!

PKCMD-LX can be used for reading and writing Microchip’s PIC range of microcontrollers, using the Pickit 2 or Pickit 3 device programmers. PKCMD-LX provides the best experience for the Linux user, developers and the professional developer community, and as a command-line utility is can be easily integrated into users scripts.

Distribution

PKCMD-LX is distributed as an AppImage. Using an AppImage enables the development team to provide native binaries for Linux users the same way we do for other operating systems. An AppImage enables the development team to package the PKCMD-LX application for common Linux operating systems, e.g., Ubuntu, Debian, openSUSE, RHEL, CentOS, Fedora etc.

The PICKitPlus AppImage comes with all dependencies that cannot be assumed to be part of each target system and will run on most Linux distributions without modifications.

Almost all major distributions are compatible with AppImages, without requiring the user to make modifications to the base system. AppImages are portable. Users can place the AppImage on a USB flash drive and run it from there, on any machine, as the users wish.

Supported Linux Distributions

Distributions known to be compatible version require libc, and these include:

  • Arch 2011.08.19
  • CentOS 7.8.2003 (released in 2020)
  • Debian 7 (Wheezy)
  • Fedora 15 (Lovelock)
  • Gentoo 11.2
  • Mint 11 (Katya)
  • openSUSE 12.1
  • Slackware 13.37
  • Ubuntu 11.04 (Natty)

Distributions that do not use libc (such as Abyss, Alpine, Sabotage, Vanilla and Void) will not run PKCMD-LX.

Free Compatibility-test Program

A compatibility-test program is available free of charge on our website:  Download our free download to see if the full product is compatible with the target computer and Operating System:  http://www.pickitplus.co.uk/distros/open/pkcmd-lx-compatibility-test.tar.gz

TI Release TPS62912, TPS62913 family of low-noise DC/DC Switching Regulators

Posted on by mixos

Texas Instruments released the TPS62912 and TPS62913 family of low-noise DC/DC switching regulators with integrated ferrite-bead compensation. They offer low noise of 20 µVRMS for frequencies ranging from 100 Hz to 100 kHz and ultra-low output-voltage ripple of 10 µVRMS.

Traditional low-noise power supply architectures include such technology like DC/DC converters, low-noise LDO, and an off-chip filter, like a ferrite bead. Integrating ferrite-bead compensation allows the TPS62912 and TPS62913 to use the already present ferrite bead as a filter against high-frequency noise and reduce power supply output voltage ripple by upwards of 30 dB.

Further, both converters offer a power-supply rejection ratio of 65 dB at up to 100 kHz. They also enable spread-spectrum frequency modulation to advance attenuate radio-frequency spurs. In addition to this, the TPS62912 and TPS62913 allow synchronization to an external clock, providing the ability to meet signal-to-noise ratios and spurious-free dynamic range targets.

Featuring a peak efficiency of 97%, the converters allow for engineers to design for noise filtering without an LDO. This reduces power losses by up to 76% and 1.8 W in analog front-end (AFE) designs and 1.5 W in designs using a wideband ADC.
