New evidence confirms Lenovo’s ‘Sapphire’ Chromebook tablet features a 13-inch display

The more we learn about ‘Sapphire’ (the high-end, Lenovo-built Chromebook tablet we’ve been tracking for months), the more it feels like this device could be at the center of a turning point for the ChromeOS ecosystem.

Last week, we confirmed that Lenovo is the manufacturer behind the scenes, and now, thanks to some new evidence found in the Chromium Gerrit, we have slightly clearer picture of the hardware’s physical footprint. If you were hoping for a smaller, handheld tablet, you might need to adjust your expectations: ‘Sapphire’ looks like it’s going to be a larger 13-inch productivity machine.

This latest discovery comes via a commit adding support for a specific BOE display panel, model NS130069-M00. While technical part numbers are usually just noise, BOE has a very predictable naming convention for its mobile and laptop panels.

By looking at previous devices, we can see that the first two digits following the prefix almost always denote the screen size. For a quick example, the HP Chromebook x2 11 used a BOE panel (NV110WTM-N61) where that “11” signaled its 11-inch display. Applying that logic here, the “13” in ‘Sapphire’s’ panel number all but confirms a 13-inch display. For the time being, however, there’s nothing publicly available on the web about this particular model.

The sweet spot for productivity

A 13-inch display on a detachable tablet is a significant statement. While 10 and 11-inch tablets are excellent for casual browsing and consumption, they often feel cramped when you try to do desktop work. Moving to 13 inches puts ‘Sapphire’ in direct competition with devices like the 13-inch iPad Pro and the Surface Pro that are generally designed for professionals who need screen real estate for multitasking.

This type of Chromebook is precisely what the ChromeOS ecosystem needs right now, especially as Google pushes forward with the “Aluminium” project. As the platform transitions to the Android kernel, we need a flagship device to lead the charge for what this new breed of Chromebooks can look like. Having a 13-inch, premium tablet/detachable could be the ultimate showcase for this more unified, optimized version of ChromeOS.

Flagship features

When you combine this 13-inch screen with everything else we already know, ‘Sapphire’ becomes one of the most ambitious Chromebook project in years. For this device that should arrive later in 2026, we’re expecting:

• MediaTek Kompanio Ultra: high-end performance with elite-tier battery life.
• Lenovo Craftsmanship: the awesome Lenovo Chromebook Plus 14 speaks for itself.
• 4-Color Light Bar: this inclusion is a direct nod to the premium Pixelbook lineage.
• Wireless Magnetic Pen: A high-end stylus solution that suggests professional-grade creative work.

While I am confident in the 13-inch size, I’m also still hunting for the specifics on resolution and refresh rate. A panel of this size begs for a high-DPI display and ideally a 120Hz refresh rate to make the most of that magnetic-charging stylus. We haven’t found those exact details in the Chromium Gerrit just yet, but I’m on the lookout for sure. Stay tuned!
