Raontech has developed core parts for smart glasses and head mounted display (HMD). It will target the virtual reality (VR) and augmented reality (AR) markets, which are emerging with the expansion of the metaverse.

Raontech announced on the 22 nd that it has released the VR·AR optical module series F2 and F2-C with built-in micro display with full HD resolution.
 
The module is composed of a micro display and a controller (control panel), and is used to make smart glasses or HMD devices.
 
Smart glasses and HMDs are worn on the face or head. A micro display should be placed in front of your eyes.
 
There have been difficulties in commercialization and mass production because the technology is difficult to apply at a short distance.
 
Raontech explained that it developed this module based on its own technology and mass production experiences related to micro display and chipset.
 
There are two types of modules: front view type (F2) and front shield type (F2-C). The front view type is suitable for smart glasses such as Google Glass, and the front shield type is suitable for video glasses for entertainment and education that require a high level of immersion.
 
Both modules feature a built-in micro display. Instead of a conventional liquid crystal display (LCD), it is equipped with a  liquid crystal on silicon (LCoS)' that forms an electronic circuit on a silicon wafer. A100-inch large screen (viewing angle of 47 degrees) can be perceived in front of your eyes through the optical module.
 
Miniaturization and lightweight technologies were also implemented. The optical module lens is 11mm thick and weighs 12g. Considering that current VR/AR glasses usually weigh around 100g, lighter products can be developed with the optical module lens. It also increased the convenience for people with glasses since the design allows to attach lens for vision correction.
 
Raontech plans to supply F2 optical module development kits and related hardware and software development platforms in order to shorten the production period for VR/AR device manufacturers. It will also provide a schematic of the smart glass that connects via USB-C.
 
Raontech plans to expand its lineup by diversifying sizes and resolutions (0.37-inch full HD, 0.5-inch HD). Bo-eun Kim, CEO of Raontech, said, “Mass production of optical components and micro displays are necessary in order for smart glasses and smart display devices to expand their usage in the metaverse era. Raontech will complete preparation for mass production and contribute to the popularization of VR·AR devices.”
