Intel has created a dual-display ‘digital Moleskine’ PC that can run Photoshop

We peeked at the future of PCs – at least, Intel’s vision of it – in a large room called the Client Experience Design Studio at the company’s Santa Clara, California headquarters. And the future appears to be a digital version of the notebook in your jacket pocket or bag – except that you can do much more than sketch on it.

Rows of tables fill the space, many of them draped with black cloth to conceal Intel’s other secrets from public view. On one table, though, Intel has revealed all: a pair of prototype PC devices with not one, but two screens – surrounded by a number of iterative prototypes that led to the final result.

The first has two different screens – one full-colour and one e-ink for simple sketches and note-taking. the second has two full-colour screens you can draw on.

Meet Tiger Rapids, the two-screen PC for your hand

The first of the prototype devices has been blessed with a public code name: Tiger Rapids, which might be called today’s two-screen PC. This is no pie-in-the-sky concept: At least two designs from Asus and Lenovo at the Computex computing tradeshow show in Taipei will be inspired by the Tiger Rapids design, explains Gregory Bryant, senior vice president and general manager of Intel’s Client Computing Group. Intel has worked about two years to refine this design, which it has provided to select partners.

Bryant explains how the prototypes express a design goal he defines as adaptable form factors. “Conceptually, it’s not a one-size fits all world,” Bryant says. “You’re going to see secondary products of different shapes and sizes, people are going to do secondary displays, obviously we’re going to work on longer-term things like bendables and foldables.”

Bryant emphasised that the motivation behind these designs was to make the PC bend to its user, not the other way around. “It’s not doing it because you can do it. It’s creating these adaptable form factors that fit the work that you’re trying to do,” Bryant added.

Competing against pen and paper

Intel’s lab is led by Murali Veeramoney, a soft-spoken but passionate man who is eager to describe in detail exactly what his small team has accomplished. (A second lab resides in Hillsboro, Oregon.) From among the prototypes of metal and plastic, he holds up something you wouldn’t normally expect to see at a technology company: a traditional pen-and-paper Moleskine notebook.

“This is a purpose-built device,” Veeramoney said, scribbling on the lined paper with a pen. “There is only one single thing you can do. So the combination of a purpose-built device with a multi-function device is what we wanted to bring.”

In other words, this is really a “notebook” PC. It’s clear that the pen-centric Tiger Rapids isn’t for everyone. But as the Moleskine demonstrates, even a niche product can win passionate fans.

Tiger Rapids opens like a traditional pen-and-paper notebook, stashing its digital pen within a pen loop to the right. It’s super-thin, skinnier than an iPhone 8 at 4.85mm thick. The left-hand screen looks relatively normal, with a traditional Windows PC desktop on a 7.9-inch LCD display. Underneath it all is a Kaby Lake Core processor, an SSD, Wi-Fi, and an undisclosed amount of memory.

What Veeramoney doesn’t say, but Windows Ink users know, is that the landing strip for e-inking within Windows is relatively small. Sure, various iterations of Windows 10 have improved the ink box from a small strip to a larger window that can intelligently move about the page. But it’s still a relatively small slice of real estate. Tiger Rapids solves that problem.

That’s because the entire right-hand screen of Tiger Rapids is an electronic paper display (EPD) that consumes almost no power. It’s purpose-built for digital inking, complete with a slight give to it that mimics traditional paper. That’s not hype, either – Veeramoney allowed me to ink on both a traditional plastic substrate as well as the EPD surface, and there was a noticeable difference. To the average user, the effort might not pay off. But to someone accustomed to pen and paper, it’s a critical detail.

Tiger Rapids’ expansion options are limited to just a single USB-C port. Intel’s partners, of course, are free to do as they choose, but the idea is that Tiger Rapids is a wirelessly connected product that might plug in just once or twice a day. The prototype’s battery life achieved 13 to 15 hours, Veeramoney said.

Double displays

More conventional dual-screen devices have gained something of a cult following, with a select group of fans wishing hard for a dual-screen device from Microsoft, for example. (No, this isn’t it.) But the basic premise is sound. By folding a pair of connected, hinged displays, users get the benefits of a larger screen while maintaining a compact form factor.


Like Tiger Rapids, Intel’s second two-screen device can be held in the hand. It uses a more traditional touchscreen display, however.

That’s the idea behind the second dual-screen device, which Intel didn’t identify by code name. The device splits the display between a left and a right half, or a top and bottom half depending upon the alignment of the screen. There’s no guile to the arrangement. Each screen serves as an independent display so that the desktop or app can span both screens.

While a traditional desktop monitor arrangement remains fixed in place, however, the dual-screen notebook can be folded back into tent mode (below)

One screen can be used as a traditional keyboard, if typing on glass is something you enjoy.

Or you can use it as a second screen. (Yeah, ok it’s a spreadsheet – but this is an Intel demo aimed at the widest possible users of this device. It could easily be Illustrator).

This second device might be called the future of dual-screen displays, but Intel executives didn’t indicate that any hardware makers planned to bring it to market at the present time. Given the success of Tiger Rapids, however, it’s possible that this device is being also shopped around to potential partners.

Shaping the future

The video below shows some of the iterative process that Intel went through to create the Tiger Rapids prototype, from the original paperboard concept through various mechanical models that explored the hinge used to connect the two screens. (It’s perhaps unfortunate that one of the more difficult aspects of the design, routing electrical connections through a structural hinge, is virtually ignored by consumers and tech reviewers.)

It’s a fascinating process. Veeramoney revealed that as far back as April 2015, Intel crafted a fake review of Tiger Rapids for its own internal use, as a sort of guideline for what they wanted to see in the real world. Tiger Rapids was designed to be half the thickness of a Moleskine – what Veeramoney calls “lay-flat computing” – but not a phone.

“That’s a completely different use case,” Veeramoney says. “We are about performance,” he says. “We will give you complete PC performance.”

You can’t help but think of Microsoft’s Surface lineup, which was originally formed to “break trail” and show partners what’s possible in the PC space. Intel already shares reference designs, essentially blueprints to build a PC, with key partners. It’s a cost-effective method that allows Intel to shoulder some or much of the engineering costs, freeing PC makers to focus on sales and marketing. (We see some possible hints at Tiger Rapids in Lenovo’s Yoga Book, a slender clamshell with a display on one side and a stylus/typing surface on the other, that came out in 2016.)

The difference, though, is that Intel has no plans, either now or in the future, to bring Tiger Rapids or any other of its cloth-shrouded concepts to market itself. In some ways, that’s oddly depressing, as Veeramoney revealed that the development process itself required literally years of work. Intel’s partners will get most of the credit. Nevertheless, it adds credence to the claim that Tiger Rapids and the other prototypes are designed strictly around the end user.

“What we believe we can do is start with an end in mind, and I don’t mean the piece of hardware or the piece of silicon or even the PC,” Bryant said. “It’s about what experience do we think is compelling, via a lot of research and a lot of end-user interviews. It’s about what experience we want to deliver to market two years out or even five years out.”

“This is us trying to inspire the ecosystem and show what’s possible.”
