1. A display comprising:
- a front panel;
a back panel spaced from the front panel, the front and back panels defining a space therebetween;
at least one pixel structure adjacent the front panel in the space between the front and back panels;
a plurality of electrical connections extending between the back panel and the at least one pixel structure; and
a plurality of thermo-mechanical elements extending between the back panel and the at least one pixel structure to dissipate heat from the at least one pixel structure toward the back panel, wherein at least one of the plurality of thermo-mechanical elements is positioned between adjacent pixel structures of the at least one pixel structure.
