According to Clay Bavor, vice president of Google VR, Google is secretly developing high-end VR displays with a leading OLED manufacturer. The OLED display has a resolution of 20 million pixels.
This resolution is very high, because a 4K display has only 8.3 million pixels, so its number of pixels is 2.5 times the number of 4K displays, and the pixel density may reach 1800PPI (depending on the panel size, we assume it is about 3.5 inches) .
There are not many display screens that can achieve 1800PPI pixel density. Even if Samsung has not yet reached this level, in May 2016 Samsung showed a 5.5-inch AMOLED display with a resolution of 3840X2160 and a pixel density of 806 PPI. According to reports, in March 2017, Samsung was able to produce 1200PPI AMOLED displays, and Samsung's next goal was to hit 1500PPI.
In November 2016, South Korean equipment manufacturer Sunic System announced that Snnic's technology is mainly based on mask evaporation and uses a planar source to vapor-deposit OLED materials, which is different from current linear sources. Planar radiation source technology deposits OLED luminescent materials on metal plates and evaporates these materials by twisting and heating the metal plates. This makes very thin and high resolution FMMs possible, which in turn can be used to make high resolution OLED displays.
Sunic System said that the technology will be able to produce 2250PPI AMOLED panels. This will undoubtedly satisfy Google’s 20-megapixel goal. Therefore, it is entirely possible that the AMOLED panel pixel density reaches 1500 PPI. The OLED manufacturer that cooperates with Google may be Samsung Display Company or LGD. Last month, it was reported that Google wanted to invest $872 million in LGD to ensure the supply of flexible OLED displays.
Google also announced that it has partnered with Sharp to develop a faster-response, higher-resolution LCD screen for VR use. This is worth paying attention to. Currently, all high-end VR helmets use OLED displays, mainly because of their relatively high speed.
