| Samsung has developed a screen with a density of 10,000 pixels |
Researchers at Samsung and Stanford University have developed an OLED screen with a density of about 10,000 pixels per square inch (PPI) that is much longer than the OLED screen you see on almost any screen. Exists, not to mention you. The screen that can be seen in modern (VR) glasses (for example (Oculus Quest) 2).
In other words, even a 6-inch screen with a resolution of 32K or 30720 x 17280 pixels cannot match because its density is close to 6000 pixels per square inch.
Pixel density is one of the main factors that determine screen quality as it is a measure of screen clarity.
The Sony Xperia 1 II offers a 4K resolution of 643 pixels per square inch (PPI), making it the clearest screen of all smartphones in 2020.
Virtual reality enthusiasts suffer from pixel gaps that become noticeable when looking at a screen too close to the eyes.
The new screen uses an OLED film to emit white light between two reflective layers, one of which is silver film and the other is reflective metal with nanoscale waves.
Each pixel in the new interface is split into four pixels of equal size. This interface can change reflective properties and allow specific colors to repeat through the pixels.
The interface contains a series of microscopic columns that are used as pixels of 2.4 μm. This design enables the pixel density to be much higher than that of your phone's OLED RGB.
The research team said: The emitted light is reflected back and forth between the reflective layers of the screen until it is emitted through the silver film on the screen surface.
The way light accumulates in the screen can achieve twice the luminous efficiency of an OLED screen with a standard white filter and higher color purity.
Ideal for virtual reality and augmented reality, this screen creates near-perfect images because you cannot see pixels or the spaces between each pixel.
A screen with a density of 10,000 pixels per square inch requires more processing power that is not yet available to consumers, but OLED technology will not be a barrier anymore.
Samsung is developing a full size screen of 10,000 pixels per square inch. The wave design makes the massive production process work.
Research by the research team at Samsung and Stanford University shows that a density of 20,000 pixels per square inch is the theoretical limit for this technology.
