A new Lenovo concept laptop called the Yoga Book Pro 3D has surfaced ahead of Mobile World Congress 2026 in Barcelona, where Lenovo is also expected to reveal other experimental hardware such as the Legion Go Fold. The device features a dual-screen clamshell design capable of delivering glasses-free stereoscopic 3D and was shared by hardware leaker Evan Blass, who indicates it will be showcased during Lenovo’s MWC presentation next week.
Promotional images show a stacked dual-display layout similar to the Yoga Book 9i, but with depth-rendered visuals projecting outward from the upper panel. Unlike traditional 3D implementations that require special eyewear, the Yoga Book Pro 3D appears designed to generate a stereoscopic effect directly through its displays.
The chassis features an integrated rear kickstand, dual USB Type-C ports, a full-sized HDMI connection, and what appears to be Lenovo’s Slim Tip power connector. The presence of the Slim Tip adapter suggests higher power delivery than typical thin-and-light dual-screen laptops, potentially indicating more demanding internal hardware.
Glasses-free 3D technology has existed for years, but implementing it effectively in laptops has proven challenging. Most systems rely on parallax barrier or lenticular lens techniques, which send slightly different images to each eye to simulate depth. Earlier consumer attempts were limited by narrow viewing angles and unstable depth rendering.
Modern implementations often combine high-resolution panels with eye-tracking cameras that dynamically adjust perspective in real time. Lenovo has not confirmed which method the Yoga Book Pro 3D uses, but contemporary glasses-free systems typically depend on tracking technology to improve depth stability and reduce viewing sensitivity.
The dual-screen configuration introduces additional engineering complexity. In conventional stacked-display laptops, the lower panel replaces a physical keyboard, with users relying on a Bluetooth keyboard accessory when needed. Extending stereoscopic rendering across one or both displays would require precise synchronization to avoid depth discontinuity, especially if content spans the two panels. Promotional imagery suggests the upper display serves as the primary 3D canvas, while the lower screen may function as a secondary workspace, though Lenovo has not detailed how interaction between the two panels is handled.
No processor or graphics specifications have been disclosed. However, glasses-free 3D rendering combined with dual high-resolution displays and potential eye-tracking hardware can increase GPU workload. Whether Lenovo equips the device with discrete graphics or a high-performance integrated solution remains unclear.
Blass has also suggested that Lenovo has recently shown a greater willingness to convert experimental concepts into retail products. In past cycles, several unconventional Lenovo prototypes progressed beyond the show floor and entered commercial production. That pattern raises the possibility that the Yoga Book Pro 3D could move beyond demonstration status.
Most desktop applications and web content are not built for stereoscopic output, limiting the practical benefits outside specialized workflows such as 3D modeling, architectural visualization, simulation, and game development.
Earlier glasses-free 3D implementations often rendered objects in layered depth planes rather than fully continuous spatial environments. If Lenovo has improved that limitation, the Yoga Book Pro 3D could represent a meaningful step forward rather than a short-lived technology showcase.
Lenovo has not confirmed pricing, availability, or hardware configuration. The Yoga Book Pro 3D is currently described as a concept device scheduled for preview at Mobile World Congress 2026 in Barcelona. Lenovo is also expected to showcase other experimental hardware at the event, including the ThinkBook Modular AI PC. Additional technical details are expected once Lenovo officially unveils the laptop.
