Samsung creates a 10,000 PPI OLED panel

Samsung is a leader in display technology and it continues to push the envelope in this industry. Samsung researchers, along with colleagues from Stanford University, have developed a new type of OLED screen with a pixel density of 10,000 PPI.

The tech is based on ultra-thin solar panels effectively coming up with a brand new architecture for OLED displays. It's the highest pixel density display in the world boasting 10,000 PPI. It's hard to say if an 800 pixels per inch display is vastly superior to a 400 one, especially when it comes to smartphones. It will be useful for devices that offer close-eye viewing experiences, such as virtual reality. When it happens though, it might revolutionize the OLED display industry, leading to immersive VR tech, insane high pixel count TVs, and smartphone display. This is caused by the gaps in between the pixels that are easily visible when looking at a display that's just centimeters from your face. This newOLED tech relies on films on emit white light between the reflective layers.

This would be ideal for VR and AR, creating a virtually "flawless" image where you can't see the screen door effect or even individual pixels. There's one silver layer coupled with one that's made of reflective metal changing the reflective properties and enabling specific colors to resonate.

In laboratory tests, the researchers claim to have successfully produced miniature proof-of-concept pixels that offer higher color purity and a twofold increase in luminescence efficiency compared to color-filtered white-OLEDs. Powering such a display would require quite a bit of computing power as well but it's all within the realm of possibility.

Samsung is working on how to integrate the development into a full-size display, the research said.
