PURPOSE: A radiation device of a round shaped-electronic display is provided to prevent damage to an electronic display. CONSTITUTION: A heat sink circuit board for radiating heat generated from a display circuit board (10) is installed inside the display circuit board. A supply pump (30) forcibly supplies external air inside an electronic display. A discharge pump (40) discharges the inner air of the electronic display to the outside. The supply pump and the discharge pump are connected through each guide duct (30', 40'). A guide air flow path (50) and a discharge air flow path (60) are included inside the electronic display. The guide air flow path guides the air supplied through the supply pump to the side of a circuit board. The discharge air flow path guides the air to the discharge pump through the guide air flow path. |
