Problems solved by technology
That is, the conventional wireless LCD device has a directional structure for receiving data unidirectionally in one direction, so that the wireless LCD device cannot transmit, for example, control data for selecting a specific image, which is used for selecting a specific image, to the main unit. The control data can only be sent through the two-way communication system
Second, the conventional wireless LCD can only perform point-to-point (or 1:1) serial communication between a mobile communication terminal and a single wireless LCD device, but cannot implement point-to-point communication between a mobile communication terminal and multiple wireless LCD devices. Multipoint (or 1:N) communication
[0010] Third, the conventional wireless LCD device does not have a key input portion such as a keypad or a touch panel attached thereto
Therefore, the user cannot perform direct image control through the key input section or the keypad, which is very inconvenient for the user
