A projection apparatus for automobile which is releasably attachable to an exterior portion of an automobile including a projection means, microprocessor; memory module; and housing which enable a selected image to be transmitted over a wireless network to the apparatus and compared with the plurality of stored images is provided. The selected image may be stored for a period of time and displayed through the projection means onto an exterior portion of the automobile for a pre-determined period of time using a timer.

Provided are a screen frame and a laser projection display device. The screen frame includes a plurality of side frames that are connected end to end, where each two adjacent side frames of the plurality of side frames are connected by at least two connectors, and the at least two connectors are connected to the each two adjacent side frames by fasteners; the at least two connectors include a first connector and a second connector, and an inserting direction of a fastener on the first connector is perpendicular to a plane where the screen frame is located, and an inserting direction of a fastener on the second connector is parallel to the plane where the screen frame is located. The present disclosure can realize accurate alignment and joining relatively easily.

A projector includes a communication unit configured to communicate with an external device, an operation unit configured to receive a user operation, and a system control unit. The system control unit is configured to validate a network function of the communication unit in response to receipt of a particular key sequence received by the operation unit in a stand-by state. The system control unit is configured not to validate the network function of the communication unit even if the operation unit receives the particular key sequence in an image projection state.
