Abstract
A light modulation module, including a liquid crystal on silicon (LCoS) display panel and a temperature adjustment module, is provided. The LCoS display panel is disposed on a transmission path of an illumination beam and is configured to modulate the illumination beam. The LCoS display panel is disposed in the temperature adjustment module, which includes a temperature sensing element and a temperature control element. The temperature sensing element is disposed next to the LCoS display panel and is configured to sense an ambient temperature of the LCoS display panel. The temperature control element is disposed next to the LCoS display panel and is coupled to the temperature sensing element. The temperature control element controls a temperature of the LCoS display panel according to the ambient temperature. A reflective projection device is also provided, which is applied with the light modulation module and has good reliability and good projection quality.
