announced Xiaomi announced its new smart wearable device called Xiaomi Smart Glasses, which is able to combine the imaging system and sensors into a precise design for ordinary glasses through MicroLED optical waveguide technology.
The company has provided enough detail to make the product concept seem somewhat plausible, at least at some point in the future. But it has no plan to actually offer it for sale.
Xiaomi Smart Glasses come in at just 51 grams and are capable of displaying messages and notifications, making calls, navigating, taking pictures and translating text right in front of your eyes.
To match the shape of ordinary eyeglasses, subtle challenges in imaging and internal component arrangements must be overcome.
Xiaomi Smart Glasses adopts MicroLED imaging technology to reduce the design space required in the structural design, as well as the overall weight of the device.
MicroLED is the perfect choice to fit the imaging system seamlessly into the frame, and like OLED, the pixels within the MicroLED are individually lit.
Its emitting feature allows for brighter screens and deeper blacks. But MicroLED has a higher pixel density and longer life with a simpler architecture.
The Xiaomi smart glasses have a display chip measuring 2.4 x 2.02 millimeters. Under the microscope, the screen is about the size of a grain of rice, with individual pixels as small as 4 micrometers – allowing the screen to fit perfectly inside the frame of the glasses.
To allow sufficient light to pass through complex optical structures before reaching the eye even in harsh direct sunlight, the company has chosen an ultra-efficient monochrome display solution, which can reach a peak brightness of 2 million lumens.
By adopting optical waveguide technology that refracts lights at 180 degrees, the MicroLED display accurately transmits light rays to the human eye through the microscopic reticular structure of the optical waveguide lens.
The reticle structure etched on the inner surface of the lens allows light to be uniquely refracted, directing it safely to the human eye.

The refraction process involves light rays bouncing countless times, allowing the human eye to see a complete image, increasing ease of use while wearing clothes.
All of this is done within a single lens, rather than using complex multi-lens, mirror or half-mirror systems as some other products do.
Optical waveguide technology significantly reduces the size and weight of the device, thus allowing smart glasses to approximate the shape of conventional glasses.
Xiaomi Smart Glasses integrate a total of 497 components including miniature sensors and communication modules. So it is not just a second screen for your smartphone. Instead, it functions as a new smart terminal with independent operational capability.
In addition to basic notification, call display, etc., it can also independently complete functions such as navigation, image capture, text and image translations in real time.
Considering the usage, key interaction logic has also been implemented to reduce outages at inappropriate times. Important information is presented in a timely manner when necessary.
The 5MP camera on the front of the glasses can take photos and translate text in photos.
And through the use of the built-in microphone and a special translation algorithm. Xiaomi Smart Glasses is able to transcribe audio to text with real-time subtitles.
The indicator light next to the camera lights up when the camera is in use to indicate that pictures are being taken.
To achieve this high level of functionality. The glasses must be equipped with a quad-core ARM processor. Plus a battery, touch panel, wireless modules, Bluetooth, Android OS and more.
These glasses will not be available to the public, and may not physically exist. However, after the Facebook announcement and just before Apple’s iPhone event. The concept display is a clear indication that Xiaomi wants to be seen as a player in the augmented reality space.
