Abstract

According to one aspect, the invention provides a device with a flexible display screen. The flexible display screen is rollable around an axis between a rolled-up state and an unrolled state. For stiffening the screen, stiffening elements are attached to the flexible display screen. The stiffening elements are compressible. They are compressed when the display screen is in a rolled-up state, so as to decrease the size of the rolled-up display device. Therefore, the invention strengthens the display, while at the same time retains a reasonable size of the display in the rolled-up state.
