Xiaomi today unveiled Xiaomi Smart Glasses, a brand new smart wearable device. Through MicroLED optical waveguide technology, Xiaomi Smart Glasses can combine imaging system and sensors into a subtle, ordinary glasses design.
Xiaomi Smart Glasses, which weigh just 51 grams, can display messages and notifications, make calls, navigate, capture photos, and translate text right in front of your eyes.
Xiaomi Smart Glasses are a glimpse into the future as seen through the eyes of an engineer.
Subtle challenges in imaging and internal component arrangements must be overcome in order to match the shape of ordinary glasses. MicroLED imaging technology is used in Xiaomi Smart Glasses to reduce the amount of design space required in structural design as well as the device’s overall weight.
MicroLED is without a doubt the best option for integrating the imaging system into the frame. MicroLED pixels are individually lit, similar to OLED pixels, and their emissive property allows for brighter displays and deeper blacks. MicroLEDs, on the other hand, have a simpler structure and a higher pixel density, as well as a longer lifespan. This allows for a more compact display as well as easier integration with other screens.
The display chip on Xiaomi Smart Glasses is only 2.4mm x 2.02mm. The display is about the size of a grain of rice under a microscope, with individual pixels measuring 4m, allowing it to fit perfectly within the frame of the glasses.
An ultra-efficient monochrome display solution is used as it is capable of reaching a peak brightness of 2 million nits to allow enough light to pass through complicated optical structures before reaching the eye, even in harsh direct sunlight.
The MicroLED display accurately transmits light beams to the human eye through the microscopic grating structure of the optical waveguide lens by using optical waveguide technology that refracts light at 180°.
The inner surface of the lens has a grating structure that allows light to be refracted in a unique way, safely directing it into the human eye. The refraction process involves repeatedly bouncing light beams, allowing the human eye to see a complete image and greatly increasing wearability.
Instead of using complicated multiple lens systems, mirrors, or half mirrors, as some other products do, all of this is done within a single lens. Optical waveguide technology allows smart glasses to approach the form factor of traditional glasses by significantly reducing device size and weight.
Xiaomi Smart Glasses include a total of 497 components, including miniature sensors and communication modules, making it more than just a “second screen” for your smartphone, but rather a standalone smart terminal.
It can perform functions such as navigation, taking photos, teleprompter, and real-time text and photo translations independently, in addition to basic notification and call display. When it comes to usage, key interaction logic has been implemented to reduce interruptions at inconvenient times and to display important information in a timely manner when it’s needed.
The front-facing 5MP camera can also take photos and translate text in photos, which is extremely useful when traveling. The glasses must have a quad-core ARM processor, battery, touch pad, Wi-Fi/Bluetooth modules, Android operating system, and more to achieve this high level of functionality.
All of this enables Xiaomi Smart Glasses to resemble traditional glasses in appearance while outperforming other smart glasses in functionality.
