LG is working on a Smartphone-Pen

LG in the future plans to release a smartphone-pen. At least, the patent for a mobile device of this type was recently registered by the company. With the advent of flexible displays, many things that previously seemed impossible are beginning to be implemented gradually. So the pen will receive two displays at the same time, one of which will be able to slide out to the required length for comfortable viewing of videos and other necessary things.

The smartphone-pen has a fingerprint sensor, a gyroscope and, of course, a camera, and everything written by it is immediately transferred to the conjugate device.
