Electronic display with cooling

A method for reducing solar loading of a display assembly, said method comprising the steps of:

• providing said display assembly comprising:
• an image assembly;
• a housing at least partially enclosing said image assembly;
• a cover located forward of, and spaced apart from, said image assembly and forming at least a portion of a forward surface of said housing;
• an airflow pathway within said housing comprising:
• a front channel between said cover and said image assembly;
• and
• a rear chamber behind said image assembly;
• a fan assembly;
• and
• one or more solar energy reduction layers associated with said cover;
• installing said display assembly in an outdoor environment;
• displaying images at said image assembly such that said images are visible through said cover;
• operating said fan assembly to move air through said airflow pathway;
• and
• preventing, by way of said one or more solar energy reduction layers, at least some ambient sunlight striking said cover from traveling beyond said one or more solar energy reduction layers and thermally interacting with said air in said front channel and striking said image assembly, thereby reducing the solar load.

A display assembly for reducing solar load from ambient sunlight, said display assembly comprising:

• an image assembly comprising:
• a liquid crystal display stack;
• and
• a backlight;
• a housing at least partially enclosing said image assembly;
• a cover assembly located forward of, and spaced apart from, said image assembly and forming at least a portion of a forward surface of said housing, wherein said cover assembly comprises multiple layers, and wherein said cover assembly is configured to permit viewing of said images displayed at said image assembly through said cover assembly;
• a front channel located between a rear surface of said cover assembly and a forward surface of said image assembly;
• a heat exchanger located behind said image assembly;
• a closed loop airflow pathway comprising said front channel and a first portion of said heat exchanger;
• an inlet located at a first area of said housing;
• an exhaust located at a second area of said housing;
• an open loop airflow pathway extending within said housing between said inlet and said exhaust and through a second portion of said heat exchanger;
• a first fan assembly configured to move circulating gas through said closed loop airflow pathway when operated;
• a second fan assembly configured to move ambient air through said open loop airflow pathway when operated;
• and
• wherein at least one of said multiple layers of said cover assembly comprises a polarizer.

A display assembly for reducing solar load from ambient sunlight, said display assembly comprising:

• an image assembly for displaying images;
• a housing at least partially enclosing said image assembly;
• a cover assembly located forward of, and spaced apart from, a front surface of said image assembly, said cover assembly comprising:
• a protective front panel;
• a first polarizer provided along an interior surface of said protective front panel;
• a second polarizer provided along an interior surface of said first polarizer;
• and
• a third polarizer provided along an interior surface of said second polarizer;
• wherein said cover assembly is configured to permit viewing of said images displayed at said image assembly through said cover assembly;
• a front channel between an interior surface of said cover assembly and a forward surface of said image assembly;
• a heat exchanger located behind said image assembly;
• a closed loop airflow pathway comprising said front channel and a first portion of said heat exchanger;
• an inlet located at a first area of said housing;
• an exhaust located at a second area of said housing;
• an open loop airflow pathway extending within said housing between said inlet and said exhaust and through a second portion of said heat exchanger;
• a first fan assembly configured to move circulating gas through said closed loop airflow pathway when operated;
• and
• a second fan assembly configured to move ambient air through said open loop airflow pathway when operated.
