Breakthrough for next-generation digital displays

In addition to the screen reacting to touch, light, fingerprints and the user’s pulse, the device can also be charged through the screen

12-Apr-2024 - Researchers at Linköping University, Sweden, have developed a digital display screen where the LEDs themselves react to touch, light, fingerprints and the user’s pulse, among other things. Their results, published in Nature Electronics, could be the start of a whole new generation of displays for ...

Clever coating turns lampshades into indoor air purifiers

17-Aug-2023 - Indoor air pollution may have met its match. Today, scientists will report that they have designed catalyst-coated lampshades that transform indoor air pollutants into harmless compounds. The lampshades work with halogen and incandescent light bulbs, and the team is extending the technology so it ...

Nanoantennas directing a bright future: White LEDs may soon be dethroned

Titanium oxides found to significantly increase efficiency and photoluminescence

23-Dec-2022 - White LEDs may soon be dethroned as the world's go-to light source by an alternative with a much better sense of direction. As a next-generation optical control technology, aphotonic crystalornanoantennais a two-dimensional structure in which nano-sized particles are arranged periodically on ...

World’s first LED lights developed from rice husks

19-Apr-2022 - Milling rice to separate the grain from the husks produces about 100 million tons of rice husk waste globally each year. Scientists searching for a scalable method to fabricate quantum dots have developed a way to recycle rice husks to create the first silicon quantum dot (QD) LED light. Their ...

LEDs from bacterial production

Sustainable light sources

26-Feb-2020 - In the FET Open project ENABLED, TU Graz protein-designer Gustav Oberdorfer is working together with researchers from Spain and Italy on environmentally friendly and inexpensive light-emitting diodes. The basis for this vision is being laid at the Institute of Biochemistry at Graz University of ...

Electric Cloth: Flexible, wearable supercapacitors based on porous nanocarbon nanocomposites

22-Oct-2019 - Evening gowns with interwoven LEDs may look extravagant, but the light sources need a constant power supply from devices that are as well wearable, durable, and lightweight. Chinese scientists have manufactured fibrous electrodes for wearable devices that are flexible and excel by their high ...

On the way to printable organic light emitting diodes

12-Jul-2019 - Organic light-emitting diodes (OLEDs) are used today in many electronic devices for display applications, ranging from smartphones to televisions. Scientists at the Max Planck Institute for Polymer Research (MPI-P) have now succeeded in developing a new design for these LEDs. They have been able ...

Radical approach for brighter LEDs

27-Nov-2018 - Scientists have discovered that semiconducting molecules with unpaired electrons, termed 'radicals' can be used to fabricate very efficient organic-light-emitting diodes (OLEDs), exploiting their quantum mechanical 'spin' property to overcome efficiency limitations for traditional, non-radical ...
