Another feature uses constricted convection to facilitate thecooling of the backlight assembly for the electronic display. Another feature uses an air curtain to further heat or cool the exteriorviewing surface of the display. Another feature uses a linear polarizer with an insulating gap to reduce the solar loading of the displaystack and provide insulation from the ambient air temperature.
