MATRIX LED DEVICE USING SMART PHONE

摘要

The present invention relates to a matrix LED device using a smart phone. The matrix LED device is capable of: displaying, in real time, information inputted in the smart phone in a matrix LED wirelessly connected to the smart phone; and editing and adding the information at any time using a wireless communication function and an LED matrix application of the smart phone. The matrix LED device comprises a smart phone which has a CPU for operation and a memory for storage to allow a new application to be installed therein and is connected to a mobile communication network of a subscribed company; a matrix LED control application which is installed in the smart phone; an LED controller which accesses to both the smart phone and the mobile communication network, receives information from the smart phone and controls the received information to be displayed in the matrix LED. The LED controller is connected to the matrix LED; the matrix LED displays the information transferred from the LED controller and is connected to an expansion unit having the same constitution as the matrix LED; and the expansion unit is connected to expand a display area if the display area of the matrix LED is small, relatively to the information to be displayed.
