A head mounted display system (HMD) includes an eyecup, an optical assembly, a backlit electronic display, and a heat management device. The heat management device couples to the eyecup on a first side and couples to the electronic display on a second side. The heat management device includes a heat dissipation structure to dissipate heat generated by the electronic display, as well as an insulating structure to thermally insulate the eyecup from the electronic display and the optical assembly.
