    Abstract: The described embodiment relates generally to the manufacture of display assemblies. More particularly the use of alternative back plates for a display assembly is discussed. By using a printed circuit board (PCB) in lieu of a metal backer heat can be evenly spread across the backer by applying a layer of copper configured to normalize a spread of heat across the printed circuit board. The configuration of the copper layer can be configured based on a tested or simulated heat map that accounts for proximate heat producing elements. The PCB can also advantageously act as an interconnection layer between other electrical components disposed within the electronic device.
