A display device includes a plurality of display modules provided to output visual information, having a bar shape, and sequentially disposed in one direction, a connection unit connecting the plurality of display modules such that the plurality of display modules are relatively moved, and a controller controlling the connection unit to relatively move the plurality of display modules to adjust daylighting using a space between the plurality of display modules.

A display system having a housing, a plurality of panels rotatably mounted in the housing and configured to present first and second display faces, each panel having first and second opposing faces that meet at opposing longitudinal first and second edges, the plurality of panels including a first panel having a portion of a first character removed from the first edge of the first panel, a second panel having a remaining portion of the first character removed from the second edge of the second panel, the first and second panels cooperating so that when the first and second panels are rotated with the respective first and second edges adjacent each other, the portion of the first character on the first panel and the remaining portion of the first character on the second panel cooperate to form a visual display of the complete first character, and a mechanism coupled to the plurality of panels and configured to cause the plurality of panels to rotate in unison in the housing and change the display face.

The present invention relates to a variably operable timber screen for three-dimensional decoration of a building exterior wall and shading control of a building, the screen comprising: a pair of rails (10a and 10b); a motor (20); a timing belt (30); several pairs of rollers (40); a plurality of columns (50); a plurality of bearings (60); a rotational force transfer bar (70); a plurality of decorative timber blade units (80); an manipulation unit (90); and a control unit (100). Therefore, the present invention can not only make the exterior of a building itself more attractive, but can also control the amount of incident sunlight through windows and doors.

A force-orienting display assembly comprising a number of display segments rotatably mounted on a movable surface, the display segments positioned proximally to each other, in a manner which reassembles picture segments to display a number of properly oriented, non-inverted pictures in a plurality of viewing orientations, where the mounting surface comprises a drum or a flat vertical surface is disclosed.

The present disclosure can be applied to display device-related technical fields and relates to a rotatable display device using, for example, light-emitting diodes (LEDs), which are semiconductor light-emitting diodes. According to the present disclosure, the rotatable display device using light-emitting diodes may comprise: a fixing unit comprising a motor; a rotation unit which is provided on the fixing unit and has a first side coupled to the motor and a second side rotatably coupled to a rotation coupling part, and rotates, the second side being a side opposite to the first side; and a light source module provided in the rotation unit and comprising at least one panel provided along a virtual cylindrical outer circumferential surface thereof and a light-emitting diode array in which individual pixels are provided on each panel in the longitudinal direction.

Electromechanical display devices and chatbots that employ one or more artificial intelligence (AI)/machine learning (ML) models are disclosed. The electromechanical display device is configured to be attached to a shelf, glass surface of a refrigerator or window, or other product storage/display and includes one or more rotating prisms that have messages on their faces. The electromechanical display devices are activated when a customer approaches. A quick response (QR) code or barcode is displayed on the electromechanical display device that, when scanned by a user's smart phone or other mobile computing system, causes an application to launch on the user's computing system that provides chatbot functionality.
