University of Minnesota Twin Cities researchers used a customized printer to fully 3D print a flexible organic light-emitting diode (OLED) display.The research team members — based at U of M mechanical engineering professor Michael McAlpine’s lab — think their work could result in relatively low-cost OLED displays. The advance could potentially aid the creation of medtech wearables and a host of other devices that rely on digital displays.
OLED display technology converts electricity into light using an organic material layer. They’re popular because they are lightweight, power-efficient, thin and flexible, with a wide viewing angle and high contrast ratio.
