## Abstract

Electronic display assemblies with forced air cooling are provided. An open loop centrifugal fan forces ambient air through an open loop pathway extending through an electronic display subassembly. A closed loop centrifugal fan forces circulating gas through a closed loop airflow pathway including a rear compartment behind the electronic display subassembly. Electronic components for operating the display assembly and changing electric vehicles may be provided with the rear compartment.
