Professor Kyung Cheol Choi and his team from the Korea Institute of Electrical Engineering, they have made remarkable achievements in ultra-thin<\/a> light-emitting diodes.<\/p>\n

The study, led by doctoral candidate Seonil Kwon, was published online Dec. 6 in the international nano journal, Nano Letters. According to the team’s prediction, this efficient and long-lasting light-emitting diode technology will be widely used in wearable displays.<\/p>\n

Current wearable displays are generally based on OLED screens. Due to the size limitation of wearable devices, the existing screens cannot achieve good display effects.<\/p>\n

In order to solve this problem, kyung’s team designed an OLED structure that is compatible with fibers. By dip-coating the three-dimensional structure of fibers, the group successfully designed a fiber-based OLED light-emitting diode.<\/p>\n

The team also demonstrated a 90 percent current efficiency for the fiber organic diode withstanding a 4.3 percent tensile strain while remaining open. Also, they can be woven into textiles and knitted garments without causing any problems.<\/p>\n

Additionally, pixel flex<\/a> this technique allows organic diodes to be fabricated on fibers thinner than a human hair. It should be noted that all work is carried out in a low temperature environment of minus 105 degrees<\/a>.<\/p>\n

Professor Choi said: “Existing wearable displays have limited applicability due to their low performance, however, this technology can fabricate high-performance fiber-optic organic diodes, and this simple, low-cost process provides Fiber optic wearable displays open a path to commercialization.”<\/p>\n","protected":false},"excerpt":{"rendered":"
