Reducing power consumption of refrigerated display case with electronic door display

A refrigerated display case system, comprising:

• a case including an internal volume;
• and
• a door system comprising:
• a movable door configured to provide access to the internal volume of the case;
• an electronic display mounted to the movable door;
• a sensor configured to indicate one or more positions of the movable door;
• at least one processor in electronic communication with the sensor and the electronic display;
• and
• a data store coupled to the at least one processor having instructions stored thereon which, when executed by the at least one processor, causes the at least one processor to perform operations comprising:
• receiving, from the sensor, sensor data comprising an indication that the movable door has been open for a time duration;
• determining, based on the sensor data, that the time duration is greater than a threshold duration;
• and
• reducing a power setting of the electronic display in response to determining that the time duration is greater than the threshold duration.

A computer-implemented method of operating a refrigerated display case, comprising:

• receiving, by one or more computers and from a sensor, sensor data comprising an indication that a movable door has been open for a time duration;
• determining, based on the sensor data, that the time duration is greater than a threshold duration;
• and
• reducing, by the one or more computers, a power setting of an electronic display mounted to the movable door in response to determining that the time duration is greater than the threshold duration.
