The present invention relates to an LED electronic signboard which simplifies a wiring between main controller and LED electronic signboard and the entire configuration and increase the transmission efficiency by making transmission and reception of image signals which are displayed on the LED electronic signboard and control signals for controlling a temperature sensor and et cetera through one optical communication cable. According to the present invention, the LED electronic signboard has an LED electronic signboard control system which includes: a main controller for simultaneously processing image signals which are made by R, G, B colors and then converted into 8 bit data and control signals which are transmitted and received to a scan board of each LED signboard connected using an optical communication cable; and a scan board including a plurality of LED modules, a module controller for controlling temperature/humidity sensor module and cooling fan module, and a FIFO processing module for simultaneously processing image signals which are transmitted from the main controller according to control of the main controller and a first control signal which is transmitted from the main controller wherein the image signals are converted from 8 bit data to 12 bit or 14 bit data is provided. Therefore, the present invention, the manufacturing and maintenance costs can be reduced, the transmission efficiency is increased and the management and maintenance are easy by simultaneously processing and controlling image and control signals.
