The design features seven auxiliary screen parts that are stored under the main screen. These displays can be taken out of the housing independently of each other. The watch case offers space for four compartments, each of which contains a maximum of two display parts.
The watch display can be unfolded into four in smartphone mode, when all 8 display parts have been extended, the phone switches to tablet mode, requiring operation with two hands.
It is not clear from the patent description whether the unfolding of the display is performed manually, semi-automatically or fully automatically.
