HoloLens Display Chip

The HoloLens, developed by Microsoft, is equipped with a cutting-edge display chip that enables seamless integration of virtual content with the real world. The device features a custom-built holographic processing unit (HPU) and an advanced waveguide display system.

The display chip used in HoloLens is a microdisplay that employs an array of micro LEDs. These micro LEDs provide high-resolution visuals with vibrant colors and excellent contrast. The display chip supports a resolution of 2k per eye, ensuring crisp and detailed images for an immersive AR experience.

What sets the HoloLens display chip apart is its wide field of view (FoV). With an FoV of 52 degrees, HoloLens offers an expansive view of virtual content seamlessly integrated into the real world. This wider FoV allows users to interact with digital objects and holograms more naturally, without the feeling of being confined to a limited display area.

Another remarkable feature of the HoloLens display chip is its ability to adjust the focus of virtual objects in real-time. The device utilizes eye-tracking technology to track the wearer’s gaze and dynamically adjust the focus of holograms accordingly. This feature enhances the realism and depth perception of virtual content, making the holograms appear as if they are part of the user’s surroundings.

In terms of refresh rate and latency, the HoloLens display chip performs admirably. It operates at a refresh rate of 60 Hz, ensuring smooth and fluid animations. The low latency of the display chip minimizes any perceivable delay between the user’s movements and the corresponding changes in the displayed content, resulting in a more responsive and immersive experience.

Furthermore, the HoloLens display chip supports various input methods, including gesture recognition, voice commands, and spatial tracking. This versatility enables users to interact with virtual elements in a natural and intuitive way, further enhancing the overall user experience.

Overall, the HoloLens display chip showcases the remarkable advancements in microdisplay technology. Its high resolution, wide FoV, dynamic focus adjustment, and low latency contribute to an exceptional AR experience. With each iteration of the HoloLens, Microsoft continues to refine and improve the display technology, pushing the boundaries of what is possible in augmented reality.


Google Glass Display Chip

Google Glass, developed by Alphabet Inc., features a compact and lightweight display chip that brings augmented reality content to the wearer’s field of view. The latest version of Google Glass, called Google Glass Enterprise Edition 2, incorporates advancements in microdisplay technology to deliver an immersive AR experience.

The display chip used in Google Glass is known as an optical waveguide display. It utilizes a miniature projector to beam images onto a transparent waveguide, which then redirects the light into the wearer’s eye. This innovative technology allows digital content to be seamlessly overlaid onto the real world without obstructing the wearer’s vision.

The optical waveguide display in Google Glass offers a resolution of 640×360 pixels, providing clear and sharp visuals for various AR applications. Although the resolution may seem lower compared to other AR devices, Google Glass compensates for this with its compact form factor and ease of use.

One notable advantage of the Google Glass display chip is its discreet display location. The small projection module is positioned above the wearer’s eye, offering a heads-up display experience. This design ensures that the augmented content remains in the wearer’s peripheral vision, allowing them to maintain awareness of their surroundings while still accessing valuable information.

In terms of field of view, Google Glass offers a narrower view compared to HoloLens, with a diagonal FoV of approximately 20 degrees. This limited FoV is designed to focus on a specific area in the wearer’s field of view, providing targeted and contextually relevant information without overwhelming the user with a large virtual display.

Google Glass incorporates advanced voice recognition technology to provide a hands-free interaction experience. Users can control the device and access information using voice commands, allowing for a seamless integration of augmented reality into daily activities.

While the Google Glass display chip may not offer the same level of resolution and wide field of view as HoloLens, it excels in its simplicity and practicality. The compact design, discreet display location, and hands-free interaction make Google Glass an ideal tool for industries such as healthcare, manufacturing, and logistics.

The development of Google Glass continues to evolve, with ongoing improvements in display technology and functionality. As the demand for augmented reality devices increases, Google Glass is poised to provide valuable solutions in various professional settings, empowering users with real-time information and enhanced productivity.
