A pair of smartglasses can be considered an augmented reality device if it performs pose tracking.  Superimposing information onto a field of view is achieved through an optical head-mounted display (OHMD) or embedded wireless glasses with transparent heads-up display (HUD) or augmented reality (AR) overlay

Smart glasses have become increasingly popular in recent years, offering their users a range of exciting applications and features. One of the key components that make these devices possible is the display.

The display used in smart glasses varies depending on the specific device, but most commonly they use either LCD or OLED (organic light-emitting diode) technology. There are many benefits to using these displays in smart glasses, including high resolution, low power consumption, and lightweight design.

LCD displays have been used in smart glasses for many years, and they remain a popular choice thanks to their high resolution and low power consumption. These displays work by using a backlight to illuminate an array of pixels, which can produce vibrant colors and sharp images. However, LCD displays do have some limitations when it comes to contrast and viewing angles, which can affect the user experience.

In recent years, OLED displays have become a popular choice for smart glasses manufacturers. These displays use organic materials to produce light, which means they are capable of producing extremely high contrast and deep blacks. Additionally, OLED displays are very thin and flexible, which makes them ideal for use in smart glasses.

Another possible display is MicroLED technology. Although it is still a relatively new technology, microLEDs have been hailed as the future of displays. They use tiny, self-emitting LEDs to produce images, which means they can offer extremely high resolution, brightness, and contrast while also being highly energy-efficient.

Overall, the display used in smart glasses is an important component that plays a crucial role in the user experience. As the technology continues to evolve, we can expect to see even more advanced and innovative displays being used in smart glasses in the years to come.
