Microsoft’s most recent patent filing hints at potential developments in the realm of foldable smartphones, diverging from its existing Surface Duo lineup. The patent suggests an exploration of a ‘true foldable’ concept, wherein a single foldable panel replaces the conventional dual-display setup connected by a hinge, akin to Samsung’s Galaxy Z Fold series.
Published by the US Patent and Trademark Office (USPTO) on February 29, the patent, titled “Foldable Computing Device Spine Cover Plate,” was officially filed on December 14, 2022. While primarily focusing on the hinge mechanism, the patent introduces a spine cover plate positioned on a vertical hinge axis, supporting the display frames. Additionally, it references a “flexible display substrate,” indicating a potential application for a foldable smartphone design.
The patent outlines the hinge’s functionality, detailing movable hinges with integrated springs for smooth device operation, ensuring secure positioning of the display frames. Although specifics beyond the hinge mechanism remain undisclosed, Microsoft’s latest patent aligns more closely with foldable smartphone trends seen in offerings from Samsung, Google, and OnePlus, deviating from its Surface Duo 2 released in 2022.
This development potentially signals a shift in Microsoft’s approach towards foldable devices, replacing the Surface Duo’s form factor. Notably, this patent aligns with a prior report from Windows Central suggesting the discontinuation of plans for a Surface Duo 3.
Despite these insights, key details about Microsoft’s envisioned foldable smartphone, such as the presence of a secondary front display or a redesigned form factor, remain unknown. It’s crucial to acknowledge that patents often don’t culminate in public product launches.
The evolution of foldable smartphones, including Microsoft’s potential entry into the segment, sparks curiosity about forthcoming innovations and design choices. For now, the patent offers a glimpse into Microsoft’s explorations, leaving enthusiasts eager for future developments in this space.
