OLED Display Market to Advance as Researchers Create a Flexile 3D-Printed Display that is Cost-Effective and can be Mass Produced

Posted On April 16, 2022     

OLEDs refer to high-quality digital displays that can be made flexible and utilized in large-scale devices like television panels and monitors all small-scale devices like smartphones. Because of their flexibility, power efficiency, small weight, and thinness, as well as their broad viewing angle and good contrast ratio, OLED displays have grown in favor. The OLED display technology relies on an organic material layer to convert power into light.

In a recent study, a flexible organic light-emitting diode (OLED) display was entirely 3D printed. This was accomplished through a customized printer in a remarkable new study. The discovery could immensely benefit the OLED Display Market. It could enable low-cost OLED displays that could be mass-produced at home using 3D printers rather than technicians' inexpensive microfabrication facilities.

Researchers wanted to see whether they could condense everything and print an OLED display on the custom-built table-top 3d printer. The idea, if successful, would cost approximately the same as a Tesla Model S.

The six device layers were created using two separate printing processes. Extrusion printing was used for the electrodes, encapsulation, insulation, and interconnects. Simultaneously spray printing was used for the active layers on the same 3d printer at room temperature. This created a 3d-printed, flexible and organic light-emitting diode display that is complete on all fronts. The 64-pixel display prototype is around 1.5 inches on each side. Every pixel functions and emits light.
The flexible 3D-printed display could potentially be wrapped in an encapsulating material, making it suitable for a wide range of applications.

Over 2,000 bending cycles, the device demonstrated relatively stable emission, indicating that fully 3D printed OLEDs could be used for crucial soft electronics and wearable devices applications.

According to the experts, the next stage is to 3D print OLED screens with increased resolution and brightness. The excellent aspect of the research is that the manufacturing is already built-in. They are set to advance their creation and will 3d print OLED displays with higher resolution and improved brightness.

Finally, the research is advantageous because all of the production is already in place. As a result, it is a hypothesis and a product that will be available shortly.
