PURPOSE: An electronic display board including an LED panel is provided to treat a screen of an LED electronic display board smoothly by preventing tile phenomenon due to standard error generated during separation and connection process of a bolt. CONSTITUTION: An LED panel approaches a frame(10). A protrusion part of a fixing unit(130) contacts an edge of the frame. Pressure is transferred from the frame by the inclined protrusion part. The fixing unit is bent downward by the pressure. The protrusion part passes through the frame. The bent fixing unit is restored to an original state. The LED panel is fixed by combining the protrusion part and the frame. During attachment and detachment process of the LED panel, the fixing unit moves toward the back of the LED panel. The protrusion part is deviated as passing the frame by bending the fixing unit downward. The LED panel is separated from the frame. |
