E Ink is turning the laptop touchpad into an e-reader for AI apps

E Ink has developed a new touchpad for laptops featuring the same electronic paper technology found in e-readers. It’s not the first company to look at the ever-growing size of laptop touchpads and see the potential of additional functionality, but instead of serving as a second smaller screen for the computer’s OS, E Ink is positioning its touchpad as a dedicated home for AI applications and assistants.

A mockup image shared by the company features a laptop with a touchpad upgraded with a color E Ink screen similar to what’s in use by devices like the Amazon Kindle Colorsoft. Instead of it being an extension of a laptop’s main screen, E Ink envisions its new touchpad as being a separate place where AI-generated text summaries could appear under your hands while working on a document, or you could maintain a constant conversation with an AI chatbot without having to juggle desktop windows.

The idea is reminiscent of laptops that companies like Asus have already released featuring upgraded touchpads that double as secondary displays, but they typically feature smartphone-sized LCD screens that are often too small to effectively use applications designed for larger computer screens. A full color screen under your hands can also be a distraction and potentially reduce a laptop’s battery life. The use of E Ink screens has expanded outside e-readers to include colorful signage and digital notepads, but the technology is still best suited to displaying text.

Similar to Apple’s now discontinued Touch Bar, E Ink also says the touchpad display could provide quick access to frequently used shortcuts, display notifications or the weather, or provide temporary playback controls without having to sacrifice a laptop keyboard’s row of function keys. It would also help reduce battery anxiety, because unlike LCD or OLED panels, E Ink’s display technology only consumes power when it’s being updated. That’s a big benefit given the higher demands of AI tools on a laptop’s battery life.

What’s not currently known are more in-depth technical specifications. Aside from the touchpad potentially using color e-paper displays, E Ink hasn’t revealed if it will adapt one of its current panels, or if it’s developed an entirely new one with increased resolutions. Today’s announcement specifically references compatibility with Intel-based AI PCs, but E Ink didn’t go into details about whether the touchpad display would be powered by a laptop’s primary OS, or if it would feature its own. The company also didn’t provide a timeline for when these touchpads might start showing up in laptops or which hardware makers may be interested.
