Therefore, this patent must now be set aside, because, as in any other patent, manufacturers keep a patent secret, to keep the idea private.
LG registered a patent, on a device consisting of three devices: a laptop, a tablet, and a smartphone.
When the device is locked it can be used as a smartphone, only on a limited screen at the top and bottom.
When the screen swipes out, from the right side it becomes a tablet computer.
The tablet computer can be transformed into a laptop computer, by extending and folding the device, so that the lower part can be used as a keyboard and the upper part as a screen.
