A display apparatus comprises: a display panel on which a screen is displayable along a first direction; a light source module including a plurality of light sources, spaced apart from each other along a second direction perpendicular to the first direction 1; a rear chassis including a plurality of coupling protrusions spaced apart from each other along the second direction; and a heat dissipation member includes a plurality of insertion holes, into which the plurality of coupling protrusions of the rear chassis are insertable, spaced apart from each other along a long axis of the heat dissipation member which extends along the second direction, and among the plurality of insertion holes, a first insertion hole at a center along the long axis and a second insertion hole adjacent to a side end of the heat dissipation member along the long axis in a shape elongated along the long axis.

A solar powered VTU and systems and methods for the same are provided. A solar energy harvesting device and an energy storage device are electrically connected to an electronic display within a housing. A support extends between the housing and the solar energy harvesting device such that a bottom surface of the solar energy harvesting device is elevated directly above, and is spaced apart from, a top surface of the housing. The solar energy harvesting device has a first footprint, and the housing has a second footprint. The first footprint is larger than, and directly overlies, the second footprint.

Field serviceable display assemblies are provided. Multiple side assemblies are mounted to a structural framework in a moveable manner, each including a channel located between a transparent layer and an electronic display, which is located behind the transparent layer. A fixed structure is positioned within a cavity located within the structural framework and between the side assemblies. The fixed structure remains stationary when the side assemblies are moved between a closed position where the cavity is enclosed, and an opened position where the fixed structure is exposed to facilitate direct access to electronic components located thereon.

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.

An electronic display device includes a housing for an electronic display to form an assembly. A thermal management subsystem forms part of the assembly and utilizes ingested ambient air from immediately outside said assembly to thermal manage the assembly. Data is received from one or more sensors pertaining to at least one characteristic of the ingested ambient air at times during operation of the assembly. Operating parameters of the assembly are automatically adjusted when the data indicates a difference in the measured at least one characteristic at the times, and when said difference exceeds a threshold value.

Methods for thermally managing a communications box of a display assembly are provided along with related systems and apparatus. Electronic components are installed within the communications box. A plate with one or more apertures is provided within, and divides, an interior portion of the communications box. One or more fans located within the communications box are activated to force a flow of air within the communications box, including through each of the one or more apertures in the convection aperture plate.

A field customizable airflow system, method, and communications box are provided. A communications box is located above an electronic display subassembly and includes one or more electronic components. The communications box includes one or more fans which cause a flow of ambient air to be accepted at an intake portion, forced through each of one or more apertures in a plate within the communications box, and be exhausted through said exhaust portion.

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.

Systems for forced air cooling of display assemblies are provided. An electronic display subassembly is located behind a cover and includes an interior channel. An open loop centrifugal fan is positioned at an intake or an exhaust and forces ambient air through an open loop pathway when activated. A closed loop airflow pathway encircles the electronic display subassembly. A closed loop centrifugal fan is positioned at a side channel and forces circulating gas through the closed loop airflow pathway. Electronic components for operating the display assembly are provided with the rear compartment.

Field customizable airflow systems, and methods related to the same, are provided. A housing for an electronic display subassembly includes an intake and an exhaust for ambient air. A communications box located above the electronic display subassembly includes one or more electronic components, a convection aperture plate with one or more apertures, an intake portion, an exhaust portion, and one or more fans which cause a flow of ambient air to be accepted at the intake portion, circulated through each of the apertures in the convection aperture plate, and exhausted through the exhaust portion when activated.
