An electronic display assembly is provided. The electronic display assembly comprises a backlight module, a transparent plate, a liquid crystal panel, an internal heat exchange path and an external heat dissipation path with ambient air flowing through. The liquid crystal panel is disposed between the transparent plate and the backlight module. The internal heat exchange path comprises a first pathway, a second pathway and a third pathway. The first pathway is arranged between the transparent plate and the liquid crystal panel. The second pathway is arranged between the liquid crystal panel and backlight module. The third pathway is located directly behind the backlight module. The external heat dissipation path carries heat conducted from air flowing through the third pathway.
