The world’s first entirely 3D printed OLED screen has been created by researchers at the University of Minnesota Twin Cities. With this advancement, you will be able to create your own 3D-printed OLED screens at home.

You won’t have to return your TV screen back to the manufacturer if it is broken in the future. You won’t have to rely on mass-produced display panels or transport them to distant factories to be repaired.
To create the six layers of materials required in OLED screens, the newly discovered technology combines two separate methods of 3D printing. The electrodes, encapsulation, insulation, and interconnects were all made by extrusion printing, while the active layers were spray-painted at room temperature.
Previous attempts at 3D printing OLED panels failed due to light uniformity concerns or used techniques other than 3D printing, such as spin coating or thermal evaporation.
The initial OLED screen had only 64 pixels and was only 1.5 inches long. Because 1080p screens require more than 2 million pixels, any feasible panel would have to be significantly larger. The researchers also intended to improve the display’s brightness and make it easy to construct in a home setting.

The university employed a specialised 3D printer that costs as much as a Tesla Model S, so it will take some time for the method to be developed enough to be as cost-effective and useful as off-the-shelf printers.
Regardless, it is a positive step forward because it opens up a world of possibilities for the future. It would allow for DIY repairs as well as the creation of personalised screens for your own gadgets.
However, it will most likely be a few years before the technology is ready for widespread usage.
