A rollable display device includes a rollable structure including a plurality of unit structures, the rollable structure being configured to be rolled and unrolled based on the unit structures, and a display panel structure attached to the rollable structure, wherein respective widths of the unit structures increase in a first direction from a first side of the rollable structure to an opposite second side of the rollable structure.

A high-resolution rollable display device is disclosed. The display device includes a rollable display panel having a first side and a second side that is longer than the first side. A printed circuit board is disposed along the first side of the rollable display panel. A plurality of flexible films are connected to the printed circuit board. In one embodiment, a first end of each of the plurality of flexible films is connected to the printed circuit board at the first side of the rollable display panel and a second end of each of the plurality of flexible films is connected to the second side of the rollable display panel.

There is provided a carrier (6) for solid-state lighting devices (2). The carrier (6) is intended to be arranged in a light bulb and is formed from one single flat and formable substrate (1), which has been bent to a generally tube-shaped form. The carrier (6) includes: an annular mounting portion (4) for mounting the carrier (6) inside the light bulb; and two or more strips (5) extending generally parallel to each other from the annular mounting portion (4) and being separated from each other in a tangential direction of the annular mounting portion (4). Each strip (5) has one or more electrically conducting paths (3) and a solid-state lighting device (2) mounted thereon. There is also provided a method for producing a tube-shaped carrier (6). The strips are easy to shape by bending, twisting and/or folding, resulting in a significant freedom in the positioning of the SSL devices.

A switching device for low or medium voltage electric power distribution networks, the switching device comprising: at least an electric pole comprising a movable contact and a fixed contact, which are coupleable/decoupleable one to another; a circuit assembly, which comprises a chain of semiconductor devices adapted to switch in an ON state or in an OFF state depending on the voltage applied thereto, the semiconductor devices being electrically connected in series one to another in such a way that a current can flow according to a predefined conduction direction (CD) when the semiconductor devices are in an ON state. The circuit assembly comprises an input terminal, an output terminal and at least an intermediate terminal electrically connected with at least an intermediate electric node positioned between two subsequent semiconductor devices. The input terminal is electrically connected with the fixed contact: the input terminal, the output terminal and the at least an intermediate terminal are electrically coupleable/decoupleable with/from the movable contact when the movable contact reaches different positions during a movement towards/away from the fixed contact in such a way that different groups of semiconductor devices switch in an ON state or in an OFF state at different instants during the movement of the movable contact, depending on the position reached by the movable contact.

An electronic device is disclosed. The electronic device includes a housing, a roller positioned inside the housing, a display panel rollable on the roller, and a guide roller positioned at an edge inside the housing. A state of the display panel with respect to the roller includes a first state in which the display panel is rolled on the roller and a second state in which the display panel is unrolled from the roller. The roller includes an outer frame which rotates when the display panel is rolled on or unrolled from the roller, and an inner frame positioned inside the outer frame and fixed to an inside of the housing regardless of rolling and unrolling the display panel.
