When Won-Jae Joo was visiting Stanford University in 2016-2018, he heard about an innovative idea there, i.e. ultra-thin solar cells that have the chance to mess up a lot of renewable energy, which immediately lit a few lamps in his head. After the presentation, it quickly became clear that Samsung would not miss such an opportunity and the units decided to cooperate, which resulted in a new architecture of organic light emitting diodes (OLED), significantly increasing the pixel density. This is a real breakthrough that can provide virtual reality with a whole new opening, deepening immersion to an unprecedented level.
Unlike the RGB OLEDs and white OLEDs currently in use, the new technology uses a base layer of a nano-scalloped reflective medal that can manipulate the reflective properties of light, allowing different colors to be displayed in pixels. During testing, scientists created miniature pixels to prove their theory, and compared to traditional OLEDs like those used in today's TVs, the prototypes offered higher color purity and double luminescent efficiency, i.e. the ratio of screen brightness to energy consumption.
What's more, with ultra-high pixel density, up to 10,000 PPI (pixel per inch), their image quality should beat modern OLED technology (we remind you that in modern smartphones we only hit 500 PPI) and eliminate some unpleasant limitations of virtual reality. How? One of the biggest problems with this technology is the so-called Screen Door Effect (SDE), which is a visible grid that separates pixels, visible when viewing the display from close range. And as it is easy to guess when using VR goggles, it is impossible to do otherwise, the users could not fully devote themselves to the experience, because it was something that kept reminding them that it was only a substitute for reality. In the case of the new technology, the mentioned mesh will not be visible at all, and as if that were not enough, the new OLEDs are also to be easier to manufacture and cost-effective. No wonder that Samsung is already working on creating a working full-size display with its use, but unfortunately we did not know any specific date here, so we have to be a bit more patient.
