A display device for a vehicle includes a first frame, a second frame configured to be move along a first direction with respect to the first frame, a roller rotatably coupled to the second frame and configured to move along the first direction based on movement of the second frame, and a flexible display that is at least partially wound around the roller and that is configured to be bent around the roller. The flexible display has an end portion fixed to the first frame. A front surface of the flexible display defines an externally exposed area that is configured to increase based on an increase of a distance between the first frame and the roller.

A multipurpose advertisement board comprising: a window; a vertical film comprising multiple film strips connected in series; a first image expression device comprising an operating unit rotatably connected to a vertical winding roller in upper and lower portions of the frame that vertically move the vertical film to display the multiple film strips in order; a horizontal film comprising multiple film strips connected in series; a second image expression device installed on the window frame, wherein the second image expression device comprises an operation unit rotatably connected to a horizontal winding roller installed in left and right portions of the window frame to rotate or release the horizontal film, thereby horizontally moving the horizontal film so that the multiple film strips of the horizontal film overlap with the film strips of the vertical film to make a combined image.

The portable backdrop for filming and photography is configured for use in filming and photography. The portable backdrop for filming and photography is an opaque structure that forms a blind used to control the image captured by a camera. The portable backdrop for filming and photography comprises a roller clutch and spring system, one or more interchangeable blinds, a fastening structure, and a suspension structure. The fastening structure attach an interchangeable blind selected from the one or more interchangeable blinds to the roller clutch and spring system. The roller clutch and spring system deploys the selected interchangeable blind during a photographic or film session. The roller clutch and spring system retracts the selected interchangeable blind onto a scroll for storage. The suspension structure suspends the roller clutch and spring system and the selected interchangeable blind from an anchor point.
