Abstract
Aspects of the disclosure include hybrid thermal management systems configured to control an operating temperature of a liquid crystal on silicon (LCoS) based head-up display (HUD) unit. An exemplary thermal management system can include a liquid crystal on silicon layer and a phase change material on a surface of the liquid crystal on silicon layer. A thermoelectric device is positioned in direct contact with the phase change material and a heat sink is positioned on a surface of the thermoelectric device. The thermal management system can further include a controller configured to adjust a thermoelectric device current of the thermoelectric device responsive to a temperature of the liquid crystal on silicon layer.
