Researchers develop 3D-printed and flexible OLED display

University of Minnesota researchers have used a customized printer to 3D print a flexible organic light-emitting diode (OLED) display. This will lead to producing low-cost OLED displays in the future. By using 3D printers anyone in home can make OLED display. They will not need technicians in expensive microfabrication facilities. The research paper has been published in Science Advances.

The OLED display technology is dependent on electricity turned into light by using an organic material layer. This can function as high quality digital displays. This can be made flexible and can be used in both large-scale devices like television screens and monitors. These displays have gained popularity because they are lightweight and power-efficient. They also offer a wide viewing angle and high contrast ratio.

Scientists previously used 3D printing OLED displays. But they faced some complexity with the uniformity of the light-emitting layers. Other scientists also partially printed displays but also relied on spin-coating evaporation to deposit certain components.

The new team of researchers combined two different modes of printing to print the six device layers. This has resulted in a fully 3D-printed and flexible organic light-emitting diode display. The electrodes and interconnects were all extrusion printed. The active layers were spray printed. It has used the same 3D printer at room temperature. The display had 64 pixels.

Scientists said that 3D-printed display is flexible and can be packaged in an encapsulating material. This will make it useful for a wide variety of applications.

Scientists said that They will improve the resolution and brightness of 3D print OLED displays.
