The global market leader among display manufacturers, Samsung, has worked with a team from Stanford University to develop a design for the construction of OLED displays that can achieve extremely high pixel densities of up to 10,000 PPI.
As the researchers and developers announced in communication from Stanford University, the revised structure for OLED panels should make ultra-high resolutions possible in the smallest of spaces. It should be possible to achieve up to 10,000 pixels per inch, which would surpass all currently available display technologies by far.
Nano dimples as pixels
The technology known as new OLED is based on the use of thin layers that emit white light and are arranged between silver and another layer of reflective metal with indentations on a nanometer scale. This so-called “optical meta-surface” changes the reflection properties and ensures that certain colors can be output by the pixels.
The pixel density can be increased extremely so that you can display significantly more pixels in the smallest of spaces than with currently available RGB OLED panels in smartphones, but at the same time, you do not have to accept compromises due to a drop in brightness, as is the case with some televisions with white OLEDs the case is. An extremely high pixel density should be advantageous in the long term, especially for applications in the field of augmented and virtual reality, since the so-called screen-door effect and the visibility of the gaps between the pixels of normal screens are currently still a problem.

It could take a while before the new display technology is widely used. Although the display technology is no longer a bottleneck, extremely increased resolutions must also be played on by correspondingly powerful graphics hardware. Samsung is already working on a “full size” display that will use the new technology.
