Abstract

An outdoor weather-resistant display may include a housing, an air-inlet, an air-outlet, a liquid crystal panel, a fan, and a thermostat. The air-inlet may be disposed through the housing into a cavity. The air-outlet may be disposed through the housing out of the cavity. The fan may be positioned to move air from outside the housing, through the air-inlet, into the cavity, across the liquid crystal panel, and out of the cavity through the air-outlet to outside the housing. The thermostat may have a temperature sensor within the cavity which provides temperature readings. The thermostat may control operation of the fan based on the temperature readings in order to regulate temperature within the cavity. The outdoor weather-resistant display may have further components to allow the display to operate in varying weather conditions, and to allow for wireless operation.
