Researchers Develop Flexible Display Cell with Quantum Dots

July 17, 2017
For the first time in the world, Kim Dae-hyeong, a researcher at the Institute for Basic Science (IBS), has developed a flexible display cell that uses quantum dots and produces more vivid colors. It is called Quantum Dot Light Emitting Diode (QLED). QLED is only 2.6-micrometer thick, and is about 1-40th of a human hair.

The new flexible display cell can be attached to human skin and, hence, can significantly improve performance of wearable devices. QLED can support up to 2,460 pixels-per-inch (ppi) resolution compared with those of latest smartphones.
QLED is claimed to be the world’s first ultra high-definition one, which is ultra thin and flexible, ideal for wearable devices. “This means that we have definitely surpassed other advanced countries such as the US in the LED sector. We can mass produce the display cells once we develop manufacturing process technology, Kim said. “We have started researching the QLED because we believed it can be used to produce ultrathin and flexible display panels,” Kim said. “We aimed at developing an LED display cell that can excel the current resolution capacity of existing display cells.” “The new display cell is thin like paper and can be attached to human skin like stickers. This means that it can be used for ultra high-definition display panel of wearable devices,” he said. Kim said his team has already submitted a patent application in Korea, and will soon file patent application globally. The research result was registered with the global academic journal Nature Communications.
