Researchers at Stanford University have used solar technology to create an ultra-high-resolution OLED display which could allow displays to reach resolutions of up to 10,000 pixels per inch.

The high pixel density displays created from this advancement could be used for future headset displays for virtual and augmented reality applications. 

As well as a groundbreaking pixel density, these ‘metaphotonic’ OLED displays have the potential to be brighter with increased colour accuracy compared to existing examples, allegedly becoming available as a cheaper and easier to produce option. 

The development is based on research by Mark Brongersma, a materials scientist at Stanford University, working in collaboration with the Samsung Advanced Institute of Technology (SAIT), initially in pursuit of an ultra-thin solar panel design. 

Brongersma commented: “We’ve taken advantage of the fact that, on the nanoscale, light can flow around objects like water.

“The field of nanoscale photonics keeps bringing new surprises and now we’re starting to impact real technologies. Our designs worked really well for solar cells and now we have a chance to impact next generation displays.”
