Abstract: Display assemblies and related systems and methods are provided which provide modified operations for condensation control. A controller calculates a dewpoint spread between a dewpoint temperature for air at the display assembly and an internal temperature for the display assembly determined based, at least in part, on data received from one or more sensors located along an airflow pathway extending within a housing for an electronic display. The controller continues to operate the display assembly in a modified operating mode until the dewpoint spread is determined to be above a predetermined threshold by at least a predetermined clear parameter. The controller continues to not operate in the modified operating mode unless and until the dewpoint spread is determined to be less than the predetermined threshold by at least a predetermined buffer parameter.

Abstract: Display assemblies and related systems and methods providing field leak testing are disclosed. An electronic display assembly includes an electronic display, a differential pressure sensor fluidly connected to an ambient environment and an internal area, and fan(s) located within, or fluidly connected with, the internal area. Differential pressure readings are taken before and while and/or after to command a speed of the fan(s) to be temporarily increased. Where an insufficient change is provided, indication of a probable leak is provided.

Abstract: A display assembly includes a framework, an electronic display subassembly connected to the framework at an elevated position, and an open, unobstructed, pass-through area located below the electronic display subassembly and within the framework. The pass-through area may assist with sightlines through the display assembly, by way of example. Wiring may be routed from a base along or through upward extending members of the framework.

Abstract: Display assemblies with condensation control are disclosed. A cover is positioned forward of an electronic display layer located within a housing. Fans and sensors are located at an airflow pathway extending within the housing. A controller receives readings from the sensors, determines which of the readings is, relatively, highest, and drives each of said fans based on the relatively highest one of the readings in accordance with a control scheme for each of the fans, where the control scheme is dependent upon the readings.

Abstract: Display assemblies for preventing delamination of an optical stack are disclosed. A continuous, interconnected airflow pathway includes each of a first, second, and third airflow passageways, where the first airflow passageway is located, at least in part, forward of the optical stack, the second airflow passageway is located, at least in part, rearward of the optical stack, and the third airflow passageway is located, at least in part, rearward of the second airflow passageway. One or more fan units are positioned along the continuous, interconnected airflow pathway, and when activated, push gas through the continuous, interconnected airflow pathway, including into the first and second airflow passageways to generate compressive forces by the gas at the optical stack.

Abstract: Digital signage units for generating air quality related alerts and providing advertising images and/or wayfinding are disclosed, along with related systems and methods. The digital signage unit includes an air quality monitoring device located along an open loop pathway for ambient air. The air quality monitoring device includes sensor(s) and receives air characteristic measurement data from the sensor(s), where the air characteristic measurement data indicates a concentration for each of certain compound(s). Where the concentration of any one of the compound(s) exceeds a respective predetermined threshold, content displayed at an electronic display of the digital signage unit is modified to include displaying an alert.

Abstract: Systems and methods for monitoring air quality of a geographic area are provided. Digital signage units include an electronic display and an air quality monitoring device located along an open loop pathway for ambient air. A monitoring subsystem receives air characteristic measurement data from the air quality monitoring devices of the digital signage units, which are installed at discrete locations within the geographic area, and subsequently generates a data summary of air characteristic measurements from the air characteristic measurement data from some or all of the digital signage units.

Abstract: Display assemblies and related systems and methods are provided which provide condensation mitigation. A cover layer forms a forward portion of a housing for an electronic display located rearward of the cover layer. A continuous airflow pathway extends entirely within the housing such that the continuous airflow pathway is partitioned from an ambient environment. One or more gaskets are provided which, at least in part, partition the continuous airflow pathway from the ambient environment. The one or more gaskets extending from an interior surface of the cover layer to a portion of the housing.

Abstract: A display assembly for preventing delamination of electronic display layers includes an electronic display subassembly at a structural framework having multiple optical layers and/or films (“the layers”). A first passageway is located between a cover forward of the electronic display subassembly and a forward one of the layers. A second passageway is located rearward of the layers. A third passageway is fluidly connected to an entrance and an exit of each of the first and second passageways. The first, second, and third passageways define, at least in part, a continuous airflow pathway. A fan unit positioned proximate to the entrance to each of the first and second passageways moves gas through the continuous airflow pathway, including into the first and second passageways in a same primary direction to generate compressive forces at the layers.

Abstract: A display assembly, communications box, and related methods are disclosed. A display assembly includes an electronic display subassembly attached to a mounting structure. A communications box attached to the mounting structure has an interior space for electronic equipment which is located above, and spaced apart from, the electronic display subassembly. A gas permeable fabric panel of the communications box occupies at least a majority of a side of the communications box and is gas permeable, such as to allow airflow to electronics contained therein.

Abstract: Display assemblies are provided. One or more electronic display subassemblies are mounted to a framework at an elevated position. An unobstructed zone is located below each of the electronic display subassemblies and within the framework. Electronic components are provided within a base portion of the framework. A panel may extend above each of the electronic display subassemblies and within the framework.

Abstract: A display assembly with condensation control includes an electronic display and airflow pathway located within the housing. At least one sensor is located along said airflow pathway. A controller in electronic communication determines a local dewpoint and an internal temperature for the display assembly based, at least in part, on data received from the at least one sensor, calculates a dewpoint spread between the dewpoint temperature and the internal temperature, and initiates modified operations where said dewpoint spread is less than a predetermined threshold.
