Samsung, Stanford researchers develop a 10,000PPI display for high-quality VR

Samsung Advanced Institute of Technology (SAIT) and Stanford University have co-developed a new OLED technology that will deliver resolutions up to 10,000 pixels per inch. The capability is much higher than what the modern displays offer. The technology is mainly targeted at the Virtual Reality (VR) and Augmented Reality (AR) devices.

A significant improvement in pixel density will help VR makers deliver high quality and probably true-to-life details to users. As of now, VR headsets grapple with issues such as ‘screen door’ effect under which the gaps between pixels are easily noticeable, especially because the display is so close to users’ eyes. The technology is said to help fix this problem.

With the new technology, researchers offer an alternative to the two types of OLED screens that are widely used. The new version comes with a base layer of reflective metal with nanoscale corrugations, which is known as optical metasurface. This metasurface is said to manipulate reflective properties of light and enable different colours in the pixels. The resonance helps facilitate an effective light extraction from the OLED displays, reports Stanford.edu.

“In lab tests, the researchers successfully produced miniature proof-of-concept pixels. Compared with colour-filtered white-OLEDs (which are used in OLED televisions) these pixels had a higher colour purity and a twofold increase in luminescence efficiency – a measure of how bright the screen is compared to how much energy it uses. They also allow for an ultra-high pixel density of 10,000 pixels-per-inch,” said the report.
