An indoor display apparatus of a vehicle may include a vehicle state inputter configured to receive a vehicle state, a front detector configured to detect an object ahead of a vehicle, a flip-dot display installed at a top of a cockpit module, and being configured to implement a pixel by rotating a flip disk, an illuminator installed around the flip-dot display, and being configured to illuminate the surface of the flip-dot display, and a controller configured to receive an operation mode of the vehicle from the vehicle state inputter, to receive a distance to the object and a direction of the object from the front detector, and to operate the flip-dot display and the illuminator.

Systems, apparatus and methods related to electronic vehicle registration and tag displays, specifically a vehicle license plate frame containing multiple low power e-paper type displays configured to replace the stickers used for vehicle registration and parking authorizations as well as provide indication of purchased parking increments and/or allow for display of advertisement or other messages. The system may also allow the display of driver or vehicle specific information such as the user's driver's license number or insurance at the request of a third party authorities such as the police. The system allows for use of a mobile computing device having software connected with the internet to access a server allowing for communication with various registrations authorities including the DMV, municipal parking authorities, and private parking authorities. Displays may be overwritten and changed depending on the location of the vehicle and need to provide display of certain authorizations.

The purpose of the present invention is to provide a magnetic fluid display in which a magnetic fluid moves in response to a magnetic field and which may display a unique visual image according to the meeting and parting of the magnetic fluid. A magnetic fluid display according to the present invention comprises: a display unit including a transparent liquid into which a magnetic fluid is injected; and a magnetic field generating unit for applying a magnetic field to the magnetic fluid at a rear surface of the display unit. When the magnetic field is applied, the magnetic fluid moves in the transparent liquid in a directional manner, so that an image may be displayed on the display unit.
