Kopin unveiled its first OLED microdisplay called the Lightning, which features a 2048 x 2048 resolution (2k x 2k) at 1" diagonal and a fast refresh rate of 120 Hz. Kopin specifically targets VR applications for this new microdisplay.
Kopin also unveiled a new optics system, which they brand as Pantile optics which is less than 30 mm thick and can be used to make thinner and lighter VR systems. A concept Pantile optics and Lightning OLED device is shown below next to a Samsung Gear VR system.
Kopin demonstrates the new Lighting OLED Microdisplay at CES, but did not reveal when this new display is expected to ship.
The ultimate test here would be Vernier acuity, but due to the early state of the device it was simply running a demo loop of test patterns rather than any arbitrary displayed image.
