LED ELECTRONIC SIGN BOARD BASED ON WIRELESS DATA TRANSMISSION

The present invention relates to an LED sign board based on wireless data transmission. The LED sign board according to the present invention includes: an LED image display unit having a plurality of unit display modules arranged in a matrix shape to form a screen for displaying an image; and an image transmission unit for processing image data to be displayed on the LED image display unit and a control signal, wherein each of the unit display modules includes an LED unit module having n×m pixels; a first wireless communications module for receiving the image data and the control signal through wireless communications; and a unit module driver for displaying the image on the LED unit module based on the image data and the control signal received through the first wireless communications module. The image transmission unit includes: a second wireless communications unit connected to the first wireless communications module of the unit display modules through wireless communications; and a main control unit for transmitting the image data and the control signal capable of allowing the unit display modules to display the corresponding image to each of the unit display modules through the first wireless communications unit. Thus, the image deterioration due to data loss or noise can be reduced. In addition, the entire LED sign board can be easily installed and the generation of errors due to a connection error or a worn-out cable can be prevented.
