For a smart stylus pen, LG has filed a patent that has the potential to replace smartphones. As per the images, the pen features two displays: One a smaller display showcasing time, notifications, and app shortcuts, and the other a flexible, foldable display that rolls "into the body of the stylus" and can be used as a conventional smartphone. Users can draw out the second screen by pressing a dedicated button located at the bottom of the stylus. All regular apps can be run by the foldable smartpen and be used for browsing and texting. The pen also features an array of sensors that are found in smartphones like a gyro, e-compass, proximity, pressure, camera, eye-tracking, and even a fingerprint reader. Further, according to the patent, users can pair the smartpen with other smart devices like a phone or a tablet and then write with it on any surface. This will make the writing appear on the paired device's screen. The pen-shaped "unusual LG smart device" will also feature a microphone and earphone which means users will be able to make calls through it.
