You do not have to send your devices (or Buy replacement parts) If the display breaks – you can create your own new screen. Researchers at the University of Minnesota Twin Cities reported this information Advanced What they say is the first fully 3D-printed flexible OLED display. Theoretically, you don’t have to rely on panels made in large, remote factories to make or repair your gadgets.

The new method combines the two methods of 3D printing to print the six layers required for a functional display. The team used extrusion printing to create electrodes, encapsulation, insulation and interconnection, while the active layers were spray-painted at room temperature. Past efforts by different teams have either had problems with light uniformity (consistency across the whole panel) or relying on external techniques of 3D printing to establish certain components such as spin-coating or thermal evaporation.

The prototype was only 1.5 inches wide and used only 64 pixels. Any practical use will require much higher resolution (more than 2 million pixels on a 1080p display), and scientists also want to improve brightness. It may also take some time for the technology to adapt to home use. The university has used a custom 3D printer which costs about a Tesla Model S. – The method may take some time to work on off-the-shelf printers, even with high-end models FormLabs’, 4,850 3B +.

The very nature of technology makes those goals relatively achievable, and opens the door to countless possibilities when home-printed OLED displays are practical. On top of repairing it yourself, it can help you create homebrew gadgets with custom screens. While this effort does not fully represent the democratization of technology production (the latter has many more parts than displays), it can reduce your reliance on companies’ pre-assembled components.
