Samsung is reportedly working on LEDoS displays offering incredibly high PPI (Pixels Per Inch) counts. These displays are planned to be used in AR and VR Headsets, with 1 notable offering from Apple.
LEDoS & Its Use In AR Headsets
Current displays just cannot output the required amount of image quality to suit the needs of AR Headsets. A typical OLED display on your mobile phone can pack around 500–600 PPI. This is quite impressive, however, AR headsets require much more clarity since the screen is closer to the eyes.
For this purpose, OLEDoS and LEDoS have been designed using silicon as a substrate instead of glass. You can read more about them here. Samsung is currently working on these displays to power future AR headsets. In addition, OLEDoS panels are also underdevelopment aimed at VR and MR headsets.
AR and VR powered worlds are now closer than ever. The basic difference being that AR adds new objects to your already-existing world whereas VR is a completely different world. Matching the ambient lighting and picture quality is a tad more difficult with Augmented Reality.
Samsung aims to develop LEDoS panels offering a whopping 6600 PPI count as mentioned by gsmarena. Kim Min-woo stated that the distance between the pixels must be 5 micrometers or less. For perspective, red blood cells are roughly 7-8 micrometers in diameter. Similarly, the RGB sub-pixels should be equal to or less than 3 micrometers. (Credit : gsmarena)
A Deeper Dive Into OLEDoS
OLEDoS basically means, OLED on Silicon. The same stands for LEDoS displays. Such displays are less than 1 inch and offer upwards of 4000-5000+ PPI (Pixels Per Inch). Apple and other companies are working on their AR offerings, however, this technology still faces a few roadblocks. Although, by 2025 OLEDoS displays may achieve market share of almost 28%.
