Enlarge / This 64-pixel OLED panel was 3D printed.
Laptops and phones with OLED displays boast rich colors at high contrasts—but they come in a premium price. Researchers from the University of Minnesota Twin Cities (UMN) say they’ve found a potential solution to that price barrier by using a THREE DIMENSIONAL printer that could eventually lead to people making their own OLED screens at home.
In a study published in Science Advances on Friday , the researchers used the custom-built printer that fits on a table and “costs about the same as a Tesla Model S, ” Michael McAlpine, a University of Minnesota professor in the Department of Mechanical Engineering and senior author of the study, said in a new statement accompanying UMN’s announcement.
While OLED panels are typically made in large microfabrication facilities by big companies like LG Display , the research could eventually result in hobbyists being able to make cheap OLED panels in their own workshops, according to the university.
