wherein the constricted convection plate provides a thermal barrier between the at least one electronic device and the electronic display.
15. The electronic display assembly from claim 14 wherein:
the at least one electronic component is for operating the electronic display.
16. The electronic display assembly from claim 14 further comprising:
at least one bracket connecting the posterior surface with the constricted convection plate.
17. The electronic display assembly from claim 14 further comprising:
a gaseous closed loop traveling across the front display surface, between the constricted convection plate and the housing, and returning to the front display surface; and
a fan positioned to propel gas around the closed loop.
18. The electronic display assembly from claim 14 wherein:
the electronic display comprises a liquid crystal display having a backlight assembly; and
the posterior surface is the rear surface of the backlight assembly.
19. The electronic display assembly from claim 14 further comprising:
a pair of sidewalls extending between the posterior surface and the constricted convection plate on opposite side thereof and substantially parallel to one another so as to further define the channel.
