Abstract
A display device includes a chassis, an electronic module, and a waterproof breathable member. The chassis has a front frame and a rear cover installed on the front frame. The rear cover has a plurality of heat-dissipating holes and an intake port, and the chassis is configured to allow a heat-dissipating airflow to pass through the accommodating space via the heat-dissipating holes and the intake port. The electronic module arranged in the chassis has a circuit board, and the heat-dissipating holes are arranged above the circuit board. The waterproof breathable member is disposed on an inner surface of the rear cover and entirely shields the heat-dissipating holes, so the heat-dissipating airflow only passes through the waterproof breathable member when the heat-dissipating airflow flows out of the chassis via the heat-dissipating holes. The waterproof breathable member is configured to avoid any liquid flowing into the chassis via the heat-dissipating holes.
