Abstract
An electronic display which can be mounted above a paved surface in an outdoor environment. A surface or plate is placed behind the electronic display to define a gap where cooling air can be drawn through said gap in order to cool the electronic display. A plurality of ribs may be placed within the gap and in thermal communication with the electronic display. The density of the ribs may be varied according to the inlet and exhaust openings for the cooling air. The ribs may be placed at a higher density near the exhaust to account for the increase in temperature of the cooling air as it travels through the gap.
