<p>A digital signage includes: a display panel; a case in which a display panel is arranged at front thereof, and includes an absorption hole formed in the lower part of a lateral surface and a discharge hole formed in an upper surface or the upper part of a back surface; a fan which allows the case to suck the air through the absorption hole and allows the air to be discharged to the discharge hole through the back surface of the display panel; a free filter which is mounted to be adjacent to the absorption hole and has multiple net knots; and a membrane filter which transmits the air passing through the free filter. Some filters are arranged on the lateral surface of the digital signage to reduce the width of the digital signage, thereby implementing a slim design.</p> |
