Abstract
A display having improved thermal management and a method for producing the display are disclosed. The display includes a pixel structure adjacent a front panel with thermo-mechanical elements extending between a back panel and the pixel structure to dissipate heat generated by the pixel structure.
Claims20
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.

An electronic 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 having a top surface adjacent the front panel and a bottom surface, each of the at least one pixel structure having a first electrode on the top surface and a second electrode on the bottom surface;
- a first electrical connection via extending between the back panel and the first electrode of one of the at least one pixel structure;
- a second electrical connection via extending between the back panel and the second electrode of the one of the at least one pixel structure;
- and
- at least one thermo-mechanical via extending between the back panel and the one of the at least one pixel structure to dissipate heat from the one of the at least one pixel structure to the back panel, wherein the at least one thermo-mechanical via is positioned between adjacent pixel structures of the at least one pixel structure.
