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.

In a display controller, a standard information acquisition unit 76-acquires at least one of a luminance characteristic and a color gamut of a standard display panel. A luminance information storage unit of an output adjustment unit stores a measurement value of a luminance characteristic of a panel of a displaying destination. A luminance range adjustment unit gradually adjusts a luminance range for an image to be a luminance range same as that of the standard display panel. A color gamut information storage unit stores a measurement value of a color gamut of the panel of the displaying destination. A color adjustment unit adjusts a pixel value of an image on the basis of the color gamut such that the image is displayed in a color same as that on the standard display panel.
