1. An electronic display assembly for digital out of home advertising with field leak testing, said electronic display assembly comprising:
a structural framework for installation at an outdoor environment;
an electronic display assembly comprises an illumination device supported by the structural framework for displaying advertising images to individuals located at the outdoor environment; an open loop airflow pathway; a closed loop airflow pathway comprising an area internal to the structural framework (“internal area”) which is partitioned from the outdoor environment; fans, a first set of which are located along the open loop airflow pathway which, when operated, move ambient air ingested from the outdoor environment through the open loop airflow pathway, and a second set of which are located along the closed loop airflow pathway which, when operated, move the gas through the closed loop airflow pathway, including through the internal area; a differential pressure sensor in fluid connection with the outdoor environment and the internal area; and a controller comprising one or more non-transitory electronic storage devices comprising software instructions, which when executed, configure one or more processors of the controller to: take at least one differential pressure reading from the differential pressure sensor; command a speed of the one or more fans to be temporarily increased; and take at least one additional differential pressure reading from the differential pressure sensor with and/or following the command to temporarily increase the speed of the one or more fans.
