Research team led by Professor Kyung Cheol Choi at the School of Electrical Engineering presented wearable displays for various applications including fashion, IT, and healthcare. Integrating OLED (organic light-emitting diode) into fabrics, the team developed the most highly flexible and reliable technology for wearable displays in the world – refer https://www.eurekalert.org/pub_releases/2017-08/tkai-tme082417.php.

“ Engineers are creating ultrathin or stretchable films with embedded electronic and photonic components, for example, or directly fabricating displays on top of textiles using inorganic and organic LEDs and polymer light-emitting electrochemical cells (PLECs). Target is to have LED fibers that could actually be woven into knitted fabrics, allowing display functions to be integrated directly into wearables that retain woven clothing’s advantages, such as flexibility, breathability and comfort.
The KAIST team, seeking to build an OLED fiber with strong enough performance for wearable displays, and with a sustainable, low-temperature manufacturing process, began with a fiber substrate made of polyethylene terephthalate (PET), a common, widely used material for plastic fibers.
When they applied a 7-volt bias to the fiber, the KAIST scientists found that the material exhibited luminance values of more than 10,000 cd/m2 and efficiencies on the order of 11 cd/A. They were able to create working OLED fibers with diameters ranging from 90 to 300 microns. And they demonstrated that the fibers could be hand-woven into actual knitted garments.”
A fiber‐based polymer light‐emitting diode (PLED) is demonstrated using dip coating, which is widely used in the textile industry. The fiber PLED shows high luminance (>1000 cd m−2) and low operating voltages (<10 V) and is safely integrated into electronic textiles. This solution process allows for low‐cost mass production by roll‐to‐roll manufacturing.
