Abstract
Display assemblies are disclosed which include a cover layer, an electronic display layer located behind the cover layer, an illumination device located rearward of, and spaced apart from, the electronic display layer, and support structures extending from a forward surface of the illumination device towards a rear surface of the electronic display layer. These support structures may be optically transmissible and support the electronic display layer, such as against rearward movement towards the illumination device.
Claims18
A display assembly comprising:
- a cover layer;
- an electronic display layer located behind the cover layer;
- an illumination device located rearward of, and spaced apart from, the electronic display layer;
- support structures extending from a forward surface of the illumination device towards a rear surface of the electronic display layer;
- a closed loop airflow pathway including:
- an illumination device passageway comprising a space between the forward surface of the illumination device and the rear surface of the electronic display laver, said support structures being thereby located in the illumination device passageway;
- a front passageway comprising a space be tween a forward surface of the electronic display layer and a rear surface of the cover layer, wherein the cover layer is spaced apart from the electronic display laver;
- and
- a rear passageway located rearward of the illumination device and fluidly connected to an entrance and an exit of each of the illumination device passageway and the front passageway;
- and
- one or more closed loop fans located along the closed loop airflow pathway for moving circulating gas within the closed loop airflow pathway when activated.
