Why constantly boast about the general super-ppi, if the real effective ppi per arcsecond is important in VR glasses. It all depends on the viewing angle - the higher it is, the lower the ppi...
Interesting that the brightness went up w/ resolution. Usually the brightness goes down w/ increase in pixel density. Crazy that this is also conventional LCD as well and not MicroLED or OLED
JDI has unveiled a 4K x 4K IPS LCD microdisplay achieving the world's highest 2527 ppi resolution for virtual and mixed-reality headsets on a glass substrate. The 2.15 in. microdisplay utilizes LTPO (low-temperature polycrystalline oxide) and COA (color filter on array) to help reduce power usage while giving users a better virtual image with less visible pixelization.
