Compound Photonics: a company overview

The company is known for developing its high-resolution, high-performance microdisplays which are used in a variety of applications, including augmented reality (AR), virtual reality (VR), head-up displays (HUDs), and other wearable technologies.

With a commitment to revolutionising display technologies, Compound Photonics focusses on the development and integration of microdisplay technologies that meet the demands of modern wearable and automotive technologies.

Liquid Crystal on Silicon (LCoS) technology

Compound Photonics is known for its work with Liquid Crystal on Silicon (LCoS) technology. LCoS is a reflective microdisplay technology that uses a liquid crystal layer on a silicon backplane. The silicon controls the voltage applied to the liquid crystals, which modulate light to create images. LCoS technology offers high pixel density, which results in detailed images. This is essential for applications like AR and VR, where image clarity is important. Additionally, LCoS microdisplays provide good brightness and colour accuracy, making them suitable for use in various lighting conditions.

The scalability of LCoS displays allows them to be used in different sizes and resolutions, making the technology adaptable to a wide range of applications.

Laser beam scanning (LBS) technology

In addition to LCoS, Compound Photonics has also explored Laser Beam Scanning (LBS) technology. LBS technology involves the use of a laser beam that is rapidly scanned across a surface to create an image. This method is more energy-efficient than traditional displays, which is beneficial for portable and wearable devices where battery life is a concern. LBS technology also allows for the creation of compact display systems, which are important for devices like AR glasses.

Optical and system-level innovation

Compound Photonics places significant emphasis on the optical systems that enhance its microdisplays. This includes developing custom optics to optimise light management and image quality. The company also focuses on integrating these systems into end products, ensuring that the displays perform well without taking up unnecessary space.

Applications and industry

Compound Photonics’ technologies are used in several markets, including AR, VR, and automotive HUDs.

In AR glasses, the high resolution and brightness of its microdisplays are important for overlaying digital information onto the real world. In VR headsets, the clarity and resolution are critical for creating immersive environments. For automotive HUDs, the brightness and contrast provided by LCoS microdisplays ensure visibility in different lighting conditions.

Collaborations

Compound Photonics has formed strategic partnerships with various industry leaders to integrate its technology into commercial products. These collaborations help to bring new display technologies to market, enabling the company to influence the direction of the industry. By working closely with device manufacturers, Compound Photonics ensures that its microdisplays meet the exacting standards required for modern consumer and industrial applications, reinforcing its position as a key player in the field.
