In April this year, Samsung announced the development of a sensor product with 600 million pixels, which directly exceeded the limit of the human eye (about 500 million pixels). And for the human eye to please, Samsung continues, this time is the display department. According to IEEE, what is the concept of < / P > < p > 10000ppi? That’s 21 times more than the iPhone 12 pro’s so-called hyper retinal XDR display (460ppi), and for many users, the iPhone 12 screen has made it hard to detect the grainy sense. < / P > < p > according to reports, the new OLED technology uses thin films to emit white light between reflective layers, one of which is silver and the other is made of reflective metal with nano ripples. This “optical element plane” changes the reflection properties, allowing specific colors to resonate through the pixels. The design allows for much higher pixel density than the RGB OLED you see on your phone, but at a cost of brightness.
