printers |
These usually do not close off ambient light to users, allowing them to see their real life surroundings. |
AR headsets |
They may have a variety of sensors including motion, external visual positioning, camera(s), motion tracking, accelerometer, gyroscope and magnetometer. Resolution and refresh rates vary. |
VR headsets |
LED is an LCD display that uses LED back lighting. LED has lower power consumption than standard LCD back lighting, so the panel can be thinner, lighter, and have better contrast. |
