Heat generation induced by electrical driving is primarily responsible for the device failure in quantum dot light-emitting diodes (QD-LEDs). Elucidating the thermally induced degeneration mechanism is crucial to enhancing operational lifetime and luminescent efficiency of the devices. Heightening heat dissipation can mitigate device degradation by utilizing high thermal conductivity materials, allowing for ultrahigh luminance and enhanced efficiency at high driving voltages.
