KAIST Develops Fiber-Like Light Emitting Diodes for Wearable Displays

13.08.2015

A research team at Korea Advanced Institute of Science and Technology (KAIST) has developed fiber-like light emitting diodes, applicable to wearable displays.

Professor Kyung-Cheol Choi and his research team from the School of Electrical Engineering at KAIST have developed fiber-like light emitting diodes, which can be applied in wearable displays. The research findings were published online in the July 14th issue of Advanced Electronic Materials.

Traditional wearable displays were manufactured on a hard substrate, which is later attached to the surface of clothes. Such technique has posed limitations in applying it for wearable displays because inflexible displays were not adequate in practice, and the characteristics of fabric were ignored.

For a solution, the research team discarded the tradition of creating light emitting displays on a plane board. Instead, they focused on fibers, a component of fabrics, and developed a fiber-like light emitting diode that has the characteristics of both fabrics and displays.

The essence of this technology, the dip coating process, is to immerse and extract a three dimensional (3-D) board that looks like a thread in a solution. Then, the regular levels of organic materials are formed as films on the board.

The dip coating process allowed the layers of organic materials to be easily created on boards with a 3-D structure including a cylinder, which had been difficult in existing processes such as heat coating process. The coating thickness can also be adjustable to hundreds of thousands of nanometers through the control of withdrawal rate.

The researchers said that this technology would accelerate the commercialization of fiber based wearable displays since it offers low-cost, mass production using roll-to-roll processing, a technology applied to create electronic devices on a roll of flexible plastics or metal foils.

Professor Choi said, “Our research will become a core technology in developing light emitting diodes on fibers, which are fundamental elements of fabrics. Hopefully, we can lower the barrier of wearable displays to enter the market.”

The first author of the published paper, Seon-Il Kwon, added, “This technology will eventually allow the production of wearable displays to be as easily as making clothes.”

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
