Modular smart television with modules independently replaceable and updatable

The invention provides a modular smart television with modules independently replaceable and updatable, comprising an application processor mainboard, a display panel, a high-capacity storage and a motion sensor. The application processor mainboard receives video information from a network, decodes the video information and outputs the decoded information to the display panel for displaying. The high-capacity storage is connected with the application processor mainboard and is used for storing local video programs. The motion sensor is used for receiving motion information and outputting the motion information to the application processor mainboard. Application software control in the application processor mainboard is converted into a corresponding motion game or motion control signal; the side of the modular smart television is internally provided with a plurality of slots; the application processor mainboard, the high-capacity storage, the motion sensor and the like are inserted into the different slots. The modular smart television has the advantages that using is more convenient, storage speed is higher and user experience is better.
