Samsung is one of the global leaders in the field of display technology and is always pushing the boundaries in this industry. This is proven by the latest fruit of this effort, an ultra-sharp OLED display with a fineness of 10 PPI, which he developed in collaboration with Stanford University.
Samsung and Stanford researchers have achieved such extreme finesse by developing an existing electrode design used in ultra-thin solar panels. The team has succeeded in creating a new architecture for OLED displays, which it says will allow devices such as smartphones, televisions or headsets for virtual and augmented reality to take advantage of the ultra-high resolution.

A display panel with a pixel density of 10 PPI would be a real breakthrough in the technology world. To give you an idea - the screens of modern phones have not yet even reached the fineness of 000 PPI. However, this technology could bring a real revolution especially to virtual and augmented reality devices.
Users of VR headsets often complain about the so-called grid effect. This is caused by the gaps between the pixels, which are easily visible when looking at the display, which is only centimeters away from the user's face.
The new OLED technology relies on thin layers that emit white light between reflective layers. There are two layers – one silver and then another that is made of reflective metal and has nano-sized corrugations. This allows the reflective properties to be changed and allows certain colors to resonate through the pixels.
Compared to RGB OLED screens in smartphones, this way high pixel density can be achieved without sacrificing brightness. The new OLED technology could create a near-perfect image in virtual reality devices, where individual pixels would be impossible to distinguish, thus eliminating the aforementioned grid effect.
Samsung said it is already working on a standard-sized screen that will use the technology. So it shouldn't be too long before we see the first devices offering an unprecedentedly fine display resolution.
