Display assemblies with replaceable covers are disclosed, along with related subassemblies, systems, and methods thereof. A cover subassembly for a display assembly includes a door frame, a plurality of clips, each removably installed to the door frame by fasteners, and a cover, a portion of which is sandwiched between a ledge of the door frame and a lip of each of the clips. The cover subassembly may be removed and replaced with a new cover subassembly. The cover of the removed cover subassembly may be replaced, such as at an offsite location, to generate a refurbished cover subassembly for subsequent installation to a same or different display assembly.

Display assembly with replaceable cover

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.

Display assemblies with differential pressure sensors

Display assemblies with enhanced fan control are disclosed. An electronic display is located within a housing. A controller receives readings from sensors located at an airflow pathway extending within the housing and determines which of the readings is, relatively, furthest from a predetermined, associated parameter. The controller drives fans located at the airflow pathway based on the relatively furthest one of the readings in accordance with a control scheme including reading-dependent, preprogrammed operating parameters for the fans.

Fan control for electronic display assemblies

Display assemblies are provided which include subassemblies attached to a structural framework, each including a passageway and at least one of which also includes an electronic display layer, an illumination device, and a forward cover. A closed loop airflow pathway for circulating gas is formed by a rear passageway behind the subassemblies and the passageway of each subassembly. Fan units associated the subassemblies and positioned to cause flow of the circulating gas within the passageways of the respective subassemblies in a respective direction.

Display assemblies inducing turbulent flow

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.

Display assemblies with condensation mitigation and related systems and methods

Electronic display assembly

Display assemblies for inhibiting delamination of an optical stack are disclosed. A structural framework defines, at least in part, an enclosure for the optical stack, which includes an electronic display layer. One or more airflow passageways are located within the enclosure and define a continuous, interconnected airflow pathway extending along one or more surfaces of the optical stack. One or more fan units are positioned along the continuous, interconnected airflow pathway, and when activated, move gas through the continuous, interconnected airflow pathway and generate compressive forces at the optical stack, thereby reducing the likelihood of delamination.

Display assemblies for providing compressive forces at electronic display layers

An electronic display assembly with ventilation, and systems and methods related to the same are provided. The electronic display assembly includes an electronic display layer, a closed loop airflow pathway, and one or more vents fluidly interposed between the closed loop airflow pathway and an ambient environment. A controller may control the vents selectively and individually between an open state and a closed state.

Display assemblies with vents

Display assemblies utilizing air characteristic data to verify internal operating conditions and related systems and methods are disclosed. The display assembly includes a side assembly, including an electronic display, is connected to a structural framework. Sensor(s) are provided, at least one of which is located at, or fluidly connected to, a closed airflow pathway. A controller receives data from the sensor(s) and determines whether an initial indication of an operating condition exists. If so, a testing routine is initiated, additional data is received from the sensor(s) during and/or thereafter. The controller confirms whether the operating condition exists based on the additional data.

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.

System and method for monitoring air quality while cooling an outdoor electronic display assembly

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.

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.

A fan unit for improved airflow within a display assembly is provided. Fans are provided at a housing which includes a rear wall opposite a forward portion and an upper surface extending therebetween. The rear wall extends laterally beyond each of the fans and defines peaks, each accommodating one of said fans and a valley between adjacent ones of the fans.
