The transparent laptop everyone on the show floor crowded around

There’s a particular sound a CES crowd makes when something actually surprises it — a low, involuntary “oh” that ripples outward from whoever’s holding the demo unit. I heard it maybe twice in four days. Both times, it was coming from the booth where a company called Folio was letting people touch the Pane: a laptop whose screen you can see straight through.

I’ll be upfront, because I spend most of these hands-on pieces talking people down from the hype: I expected a gimmick. A novelty panel with a viewing angle measured in degrees and a contrast ratio that collapses the second a room light is on. What I got was more interesting and more complicated than that, which is exactly why I’m still thinking about it a day later.

What it’s actually like to use

The Pane is a 14-inch transparent micro-LED panel — Folio’s reps quoted 1,500 nits peak, and I believe roughly that, because it held up under the booth’s punishing overhead lighting better than half the opaque screens nearby. When the laptop is off, the lid is a sheet of slightly smoky glass. Power it on and the image floats on that glass, with whatever is behind the screen still faintly visible through the dark parts of the picture.

Typing on it is the strange part. You see your own hands through the keyboard area of the display, ghosted behind your spreadsheet. Folio has a software toggle that drops an opaque backing layer — an e-ink-style shutter behind the panel — for when you want a normal laptop, and honestly that mode is where I’d live. The transparency is a party trick about 90 percent of the time. But that other 10 percent is doing something I haven’t seen before.

The reps walked me through the use case that justifies it: design and engineering work where you want to overlay digital content on a physical object behind the screen. Hold a real circuit board behind the Pane, line up the schematic on screen, and you’ve got a poor man’s augmented-reality bench without strapping anything to your face. A jewelry designer at the booth was using it to mock up settings over actual stones. In those moments the “oh” makes sense. The screen stops being a window you look at and becomes a layer you look through.

The parts they didn’t put on the placard

Battery is the obvious problem, and Folio was cagey about it. Driving a transparent micro-LED panel at high brightness is expensive, and the number I eventually pried loose — “around five hours of mixed use” — is a number I’d treat as optimistic until I can run it down myself. The unit also ran warm along the hinge after ten minutes of demo loops, which at a trade show booth means “watch this carefully in a real review.”

Then there’s contrast. Transparent displays cheat black by simply not lighting those pixels, which means true black is “whatever is behind your laptop.” Point the Pane at a white wall and dark UI elements turn into murky gray suggestions. The opaque-backing mode fixes it completely, which rather tells you which mode the engineers trust.

Price, when I asked, got a nervous laugh and “premium, but we want it in real hands.” Read that as expensive. A first-gen transparent panel does not get cheap, and Folio is a small company swinging hard. The version on the floor felt like a working product, not a render — and at this show, with this kind of crowd, that already puts it ahead of most of what I saw.

Should you care yet

Not as your next laptop. The Pane is a first attempt at a category that may or may not have a second attempt, and buying first-gen anything from a startup is how you end up with a beautiful brick in a drawer. Our wider CES coverage runs through the gadgets that are closer to ready for your money; this is not one of them.

But I came away from the booth more convinced than when I joined the line, and that almost never happens to me at CES. Transparent computing has been a sci-fi prop for thirty years and a vaporware render for ten, and Folio put a working one in my hands that did something useful for at least part of the time I held it. The crowd’s instinct was right. The “oh” was earned. Whether the company survives long enough to fix the battery and the black levels is the only question that matters — and it’s the one nobody at the booth could answer.

I’d wait. But I’d keep my eye on it, which is more than I can say for the connected fork two aisles over.
