Micro-display Technologies for AR/ VR & HUDs

Updated: Mar 17

Micro-displays have evolved significantly since their introduction in the 90s, originally used in devices like Rear Projection TVs and digital camera viewfinders. Today, they are crucial components in AR, VR, smart glasses, HMDs, and HUD systems, driving the market's expected growth from ~$1B in 2018 to ~$3.5B by 2024. 

Correspondingly, the technology is improving all the time and micro-displays' manufacturers make significant investments in order to improve their technology and products performances. In addition, new technologies and manufacturers enter this field.


Micro-display Market Expansion


The increasing adoption of HMDs and AR/VR headsets in a variety of applications in different markets, such as military (avionics, simulators, field combat), medical, automotive, consumers and entertainment, is expected to drive micro-displays' market growth in the upcoming future.


Sharing Expertise: Our Recent Paper


At JOYA Team, we actively share our expertise within the XR community. One platform we utilize is the OLED-info website, where we recently published a paper on Micro-display Technologies for Augmented Reality authored by Assaf Levy-Beeri. This paper showcases our expertise in display technologies and their application in XR product development.

As part of our services portfolio, we provide electro-optics technologies consulting and their integration in optical systems as part of the optical product development or as a standalone service.


Understanding Micro-display Technologies for AR and HUDs


In this comprehensive article, we delve into the unique world of micro-display technologies for augmented reality (AR) and head-up displays (HUDs).

Micro-displays serve as integral components in various wearable products, each offering distinct advantages and applications. The selection of micro-display technology hinges on key factors such as size, weight, cost, and performance. Three primary types of micro-displays dominate the landscape: transmissive, reflective, and emissive.


Emissive Technologies: OLED and Micro-LED

Among emissive technologies, OLED stands out for its energy efficiency and superior image quality, but especially for its size and the fact that it doesn't need any illumination source. That makes this technology ideal for AR applications. However, its suitability for applications requiring high luminance levels is limited. On the horizon, micro-LED emerges as a promising technology, with the potential for high brightness. Despite its potential, technical challenges must be overcome for widespread adoption.


Exploring Reflective and Transmissive Micro-displays

Reflective and transmissive micro-displays, such as LCoS, LCD, and DLP, each have their own set of advantages and disadvantages. These are thoroughly explored in the article, providing readers with a comprehensive understanding of these technologies.
