PURPOSE: An electronic display module having an excellent waterproof-heat radiation function and an electronic display board using the module withstand external shocks and have an excellent waterproof effect by preventing the penetration of water or moisture. CONSTITUTION: An electronic display module (10) includes a front cover (100), a protective member (200), a printed circuit board (300), and a rear casing (400). The front cover punches multiple open holes on a front panel formed on a square edge member in a grating form and includes shielding protrusions for shielding sunlight at the upper part and both sides of the open hole. The protective member has multiple protrusions inserted into the respective open hole of the front cover and diffuses light by being made of transparent materials. The printed circuit board inserts an LED lamp mounted on the front side inside the protrusion of the protective member. The rear casing inserts the printed circuit board inside a square support frame, forms a rear panel formed on the rear surface of the square support frame in a honeycomb form, and radiates heat by brining a honeycomb-shaped mold part into contact with the printed circuit board. |
