Visionox developed a 814 PPI VR AMOLED display
A somewhat confusing article from Taiwan claims that Visionox developed a new VR AMOLED display that achieves a very high pixel density of 814 PPI.
The original article only actually refers to Black Cattle Food - which is a Chinese soy and grain beverage maker that teamed up with Visionox and provided financial support for Visionox' upcoming 6-Gen flexible AMOLED fab.
