A 12.3 inch FHD flexible AMOLED display module for vehicle application was produced and the heat dissipation was studied. Passive thermal management technology was investigated and a simplified steady heat transfer model was established to analysis the thermal properties of the vehicle AMOLED display module. The simulation results were good consistent with the measured data. By optimizing the structure and materials of heat dissipation, the surface temperature of the AMOLED display module with the luminance of 800 cd/m 2 at full white pattern can be decreased to 42.5 °C which was 4.1 °C lower than that of without any dissipation films.
