An image for communication with outside pedestrians is implemented by an afterimage effect by means of a cylindrical display installed at an upper end of a mobility vehicle, and visibility is ensured. In addition, the number of light sources for implementing the image is reduced, an overall size of a lighting device is reduced, and durability and reliability are improved because there is no direct mechanical contact.

An energy harvesting device and a display device are provided. The energy harvesting device is configured to generate a power signal and the energy harvesting device includes a slot antenna. The slot antenna comprises a first section and a second section. The first section of the slot antenna is a linear shape and comprises an opening end, and the second section of the slot antenna is a bending shape and comprises a plurality of continuously bending corners.

An electronic label with a housing, that comprises a front wall and a rear wall and a side wall, wherein the front wall comprises a, particularly reflective, screen, and wherein by contrast to the front wall and rear wall, the side wall is constructed to be light-conducting and wherein a light source for emitting the light that can be generated using it through the side wall is positioned inside the housing, and wherein the side wall is inclined towards the front wall.

A control method of a lighting apparatus for a vehicle may include: sensing, by a sensing unit, a distance between the vehicle and a pedestrian; determining, by a control unit, whether the distance between the vehicle and the pedestrian falls within a first distance; determining, by the control unit, a walking direction of the pedestrian when the distance between the vehicle and the pedestrian falls within the first distance; and indicating, by the control unit, the walking direction to the pedestrian by operating a plurality of flap units.

A display apparatus include a display module, a cover plate, and a lifting module. The display module includes a display panel that displays an image in a display area. The display area includes an Always On Display (AOD) area. The cover plate covers a portion of the display module. The lifting module moves vertically the cover plate. At least the AOD area of the display area is not covered with the cover plate and is exposed to an outside. AOD data is displayed in the AOD area. Thus, an AOD function can be implemented.
