Claim 0:
1. A system for leak testing an electronic display assembly, said system comprising:
the electronic display assembly comprising a testing area, a differential pressure sensor configured to detect a differential pressure between ambient air of an ambient environment and gas within the testing area, an illumination device, an open loop airlfow pathway, one or more fans associated with the open loop aiflow pathway and configured to ingest, circulate, and exhaust a flow of the ambient air through the open loop airlfow pathway when operated, a closed loop airflow pathway comprising the testing area, and one or more fans associated with the closed loop airflow pathway and configured to circulate the gas through the closed loop airflow pathway when operated;
a controller in electronic communication with the differential pressure sensor and configured to:
turn off the illumination device, 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 and take a differential pressure reading the differential pressure sensor to determine a baseline differential pressure reading;
determine differential pressure readings for the electronic display assembly based on data received from the differential pressure sensor; and
selectively generate electronic notifications based on said differential pressure readings.
