Professors at the Korea Advanced Institute of Science and Technology have succeeded in creating an ultra-thin and highly efficient OLED screen. The team has stated that this new technology will hopefully be used in a series of wearable displays, hopefully changing the entirety of the field on wearables. Existing technology in the space has seen a slow amount of performance given the weight and density of the materials. The low performance has made a series of limitations when attempting to build upon these existing platforms.

With new technology in the space, new innovation can likely be made. According to a report on the new technology “the team designed a structure of OLEDs compatible to fiber and used a dip-coating method in a three-dimensional structure of fibers. Through this method, the team successfully developed efficient OLEDs that are designed to last a lifetime and are still equivalent to those on planar substrates.” The report further states that “The team identified that solution process planar OLEDs can be applied to fibers without any reduction in performance through the technology.

This fiber OLEDs exhibited luminance and current efficiency values of over 10,000 cd/m^2(candela/square meter) and 11 cd/A (candela/ampere). The team also verified that the fiber OLEDs withstood tensile strains of up to 4.3 percent while retaining more than 90 percent of their current efficiency. In addition, they could be woven into textiles and knitted clothes without causing any problems.” This new technology can be applied to a series of fields and products. In the near future, the likelihood of a breakthrough like this will be well noted in the scientific community. Once this technology is able to perfected, it will likely be used on many of the current day products.
