## Abstract

A display assembly includes a mounting structure with one or more cavities for electronic equipment located along a dedicated central airflow pathway for a first flow of ambient air. Each of a number of side assemblies are attached to a respective side of the mounting structure and include a front cover, a display layer located rearward of the front cover, an illumination device for illuminating the display layer when operated, and one or more dedicated side assembly airflow pathways.

## Claims

### Claim 1

A display assembly comprising:
a mounting structure comprising a dedicated central airflow pathway for a first flow of ambient air and one or more cavities for electronic equipment located along said dedicated central airflow pathway; and
a number of side assemblies, each attached to a respective side of said mounting structure and comprising a front cover, a display layer located rearward of the front cover, an illumination device configured to illuminate the display layer when operated, one or more dedicated side assembly airflow pathways comprising a cooling channel for a dedicated flow of the ambient air and a closed loop airflow pathway for a dedicated flow of circulating gas;
wherein said electronic equipment, which comprises electric vehicle (“EV”) charging equipment, is configured to provide functionality other than operation of said number of side assemblies;
wherein said central airflow pathway, said cooling channels of said number of side assemblies, and said closed loop airflow pathways of said number of side assemblies are separated from one another inside the display assembly in accordance with at least ingress protection code IP65 ratings.

### Claim 2 (depends on 1)

The display assembly of claim 1 wherein:
said closed loop airflow pathway of each of said number of side assemblies comprises a front channel located between said front cover and said display layer and a rear channel located behind said cooling channel; and
said cooling channel of each of said number of side assemblies extends along a rear surface of said illumination device.

### Claim 3 (depends on 2)

The display assembly of claim 2 wherein:
said display layer of each of said number of side assemblies comprises at least one liquid crystal cell;
said illumination device of each of said number of side assemblies comprises a number of light emitting diodes arranged to provide direct backlighting to said display layer; and
said front cover of each of said number of side assemblies comprises multiple layers including two layers of a transparent or translucent material, at least one polarizer or anti-reflective film provided on one of the at least two layers, and an optical adhesive interposed between the two layers.

### Claim 4 (depends on 1)

The display assembly of claim 1 wherein:
said electronic equipment is electrically independent of said number of side assemblies.

### Claim 5 (depends on 1)

The display assembly of claim 1 wherein:
said one or more cavities comprise an upper cavity located between said number of side assemblies and a lower cavity located below the number of side assemblies;
said mounting structure comprises a recessed compartment which extends into the upper cavity;
a first portion of said EV charging equipment is located within an exposed portion of said recessed compartment; and
a second portion of said EV charging equipment is located within said lower cavity.

### Claim 6 (depends on 1)

The display assembly of claim 1 further comprising:
additional electronic equipment located at each of the number of side assemblies for operating said number of side assemblies.

### Claim 7 (depends on 1)

The display assembly of claim 1 wherein:
each of said number of side assemblies is moveably mounted to said mounting structure; and
said number of side assemblies comprise at least two of the side assemblies positioned at said mounting structure to face in opposing directions.

### Claim 8 (depends on 1)

The display assembly of claim 1 further comprising:
a first set of one or more fans configured to provide said first flow of said ambient air through said dedicated central airflow pathway when operated;
an additional set of one or more fans provided at each of said number of side assemblies and configured to provide said additional flows of the ambient air when operated; and
a second additional set of one or more fans provided at each of said number of side assemblies and configured to provide said flow of the circulating gas when operated.

### Claim 9

A display assembly comprising:
a mounting structure comprising an intake area, an exhaust area, and one or more cavities, wherein said intake area, said exhaust area, and said one or more cavities define, at least in part, a dedicated central airflow pathway for a first flow of ambient air;
