Abstract
Thermal management in a display system can be implemented using at least one temperature regulating element (TRE). The display system can include an array of light emitting diodes or some other type of light emitter. Each light emitter of the array includes an active region configured to emit light and can be formed from a shared semiconductor structure in which the at least one TRE is located. Each TRE includes a phase change material configured to undergo a phase transition from a first state of matter to a second state of matter in response to heat, such that at least some of the heat is expended in causing the phase transition instead of heating an area around the TRE. In this manner, the at least one TRE can operate as a passive cooling solution for regulating the temperatures of the light emitters.
