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 distributed airflow are provided. Side assemblies, each having a display layer located behind a cover are connected to a frame. A cavity is located, at least in part, between the side assemblies and spaced apart side panels of a frame. Open airflow pathways are fluidly connected to an ambient environment by way of an intake and extend, at least in part, along a rear portion of the electronic display subassembly of a respective one of the side assemblies to a respective one of exhausts. A closed airflow pathway includes the cavity and is fluidly separated from the ambient environment and the open airflow pathways, and extends, in part, within each of the side assemblies. A first set of fans is provided at or along the intake, and a second set of fans is provided at or along one of the side panels.

Display assemblies incorporating electric vehicle charging equipment

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 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

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.

Fan unit for providing improved airflow within display assemblies

Display assemblies providing electric vehicle charging are disclosed which include side assemblies connected to a frame having an electronic display and power supplies and electric vehicle charging equipment, including internal and external components. The electric vehicle charging equipment and the one or more side assemblies are each connectable to an external power supply in a manner which electrically separates power supplied to at least a bulk energy storage device of the electric vehicle charging equipment from power supplied to at least an electronic display subassembly power supply of the one or more side assemblies.

Display assemblies with divided interior space and related methods are disclosed. A common passageway for the gas fluidly connects passageways of a first and second electronic display subassembly. A barrier extends within, and partitions, the common passageway into a first portion and a second portion. A continuous airflow pathway for the gas includes the first and second portions of said common passageway and the passageways of the first and second electronic display subassemblies. The first and second portions being fluidly interconnected by the passageways of the first and second electronic display assemblies.

Display assembly with divided interior space

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.

A display assembly with divided interior space includes a common passageway which fluidly connects passageways of first and second electronic display subassemblies where the common passageway and passageways of the electronic display subassemblies form, at least in part, a continuous airflow pathway for gas. A central septum extends within the common passageway to prevent the gas from directly traveling between a first portion and a second portion of the common passageway, defined, at least in part, by the central septum. Each of the portions of the common passageway are fluidly connected with the passageways of the first and second electronic display subassemblies.

A display assembly with electric vehicle charging equipment includes one or more side assemblies, each connected to a structural frame and including an electronic display subassembly. An external portion of the electric vehicle charging equipment is connected to the structural frame and located rearward of the cover of each of the one or more side assemblies, where the cover is located forward of a display layer. An internal portion of the electric vehicle charging equipment is located at a cavity provided below or rearward of the cover of each of the one or more side assemblies.

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.

A display assembly includes a structural framework, a cover forward of an electronic display layer, and an illumination device rearward of the electronic display layer. A rear passageway is provided between a rear portion of the structural framework and a rear surface of the illumination device and is in fluid communication with a front passageway between a rear surface of the cover and a forward surface of the electronic display layer and an illumination device passageway between a rear surface of the electronic display layer and a front surface of the illumination device. A closed loop fan unit adjacent to an entrance to the front passageway and the illumination device passageway creates flows of circulating gas therethrough when activated.

Systems and methods for detecting and alerting to likely leaks in an electronic display assembly are provided. An electronic display assembly includes an electronic display, a testing area, and a differential pressure sensor fluidly connected to ambient air in an ambient environment and gas within the testing area. A controller determines one or more differential pressure readings based on data received from the differential pressure sensor, and generates and transmits an electronic notification where the differential pressure readings are below a predetermined threshold.

A display assembly with divided interior space includes a first and second electronic display subassembly attached to a structural framework, where each of the subassemblies include an electronic display layer located behind a cover, an illumination device for providing illumination to the electronic display layer when powered, and a passageway for circulating gas. A common passageway for the circulating gas is located between the subassemblies and is in fluid communication with the passageways. A central septum extends within the common passageway between the subassemblies to divide the common passageway into a first portion and a second portion.
