The electronic display includes a channel sign used as a small electronic display displaying a desired character or figure, and a large electronic display for displaying various information as a still image or a moving image. The method of controlling the electric signboard is a method in which the controller switches and drives the power of the light emitting module according to the size of the signboard (hereinafter referred to as a switching method) and a method of transmitting and driving a data signal to the module controller of the light emitting module. (Hereinafter referred to as "transfer method").

The dimming control system to which the switching method is applied is applied to a small display board for displaying a desired character or figure in mono or color, and includes a controller, a power supply unit, and a plurality of light emitting modules. The control unit is composed of a switch unit consisting of a controller and a plurality of field effect transistors (FETs).
