With the latest redesign of the MacBook Pro, Apple introduced the Touch Bar, a small OLED display that replaced the function keys at the top of the keyboard. But the company might be looking to take that concept much further, with a new patent for a full OLED display keyboard, via Apple Insider.

In other words, Apple’s patent answers the unasked question, “What if the Touch Bar was the entire keyboard?”

Apple, 2019: “We’d like to introduce the MacBook Pro 2. We’ve heard your feedback, and have replaced the entire keyboard with touchbars.” — Chaim Gartenberg (@cgartenberg) January 4, 2018

The patent (first spotted by Patently Apple) is officially for a “dual display equipment with enhanced visibility and suppressed reflections,” and describes two versions of what a final device could look like. One sounds more like a MacBook, where the two screens are part of a single device, connected by a hinge, while the other describes the second keyboard-screen as an accessory for a device (like an iPad keyboard accessory, for instance.)

The patent also describes use of polarizers in order to minimize reflections from the two screens onto each other, which is a clever addition to solve that problem should Apple actually look to build this as a real device.

Of course, for now this is just a patent, which doesn’t actually mean we’ll see it on any hardware in the future. (Given the somewhat lackluster reaction to the Touch Bar, that might not necessarily be a bad thing.)
