A four-way dual scanning electronic display board capable of scan control, whereby, in order to provide drive control, an LED module arrangement method, and processing for each LED pixel dot (R, G, B), which are for easily enabling a high definition image, pixel display dots of an LED module are controlled by processing image display dots of the module by means of a four-way method by an automatic image switching device through the display control of SCU image switching, in order to display a high definition image through the four-way control of each image dot (R, G, B) pixel, and thus high resolution image quality may be enabled and displayed.
