Claim 15:
16. An electronic display assembly configured to facilitate leak testing, said electronic display assembly comprising:
a housing;
an electronic display located within the housing;
a closed loop airflow pathway for circulating gas extending within the housing and comprising a testing area;
a differential pressure sensor fluidly connected to said testing area and an ambient environment, wherein said differential pressure sensor is configured to detect a differential pressure between ambient air and the circulating gas;
fans located within the housing;
a controller in electronic communication with the differential pressure sensor, the one or more fans associated with the open loop airflow pathway, and the one or more fans associated with the closed loop airflow pathway, said controller configured to:
determine a baseline differential pressure reading by turning off the fans and an illumination device associated with the electronic display and subsequently taking a differential pressure reading from the differential pressure sensor;
take operational differential pressure readings for the testing area way of the differential pressure sensor while the fans and the illumination device are active; and
generate an electronic notification indicating a suspected leak where the operational differential pressure readings are maintained within a margin of the baseline differential pressure reading.
