The Xiaomi Smart Glasses use “microLED optical waveguide technology” to beam an image onto one of the glasses lenses, which users can then use to check their messages and notifications; make calls; navigate; capture photos, and translate text.
Xiaomi said it opted to use microLEDs because allowed for a petite imaging system that could fit seamlessly into the frame. MicroLEDs are an emerging display technology that combine the benefits of both LCDs and OLED displays, although they are not yet in mass production.
The technology uses individually lit pixels that allows for brighter displays and deeper blacks. They also have a higher pixel density and longer lifespan while having a simpler structure which allows for a more compact display.
Under a microscope, the display is roughly the size of a grain of rice, with individual pixels sized at 4μm, enabling it to be fitted perfectly within the frame of the glasses. To allow sufficient light...
