| Zusammenfassung: | The present disclosure provides a light modulator including: a first light modulating portion, a second light modulating portion, and a liquid crystal layer. The first light modulating portion includes a first substrate, a first transparent conductive layer and a first heat conducting layer disposed on the first substrate. The second light modulating portion is disposed opposite to the first light modulating portion. The second light modulating portion includes a second substrate and a second transparent conductive layer and a second heat conductive layer disposed on the second substrate. The second heat conducting layer and the first heat conducting layer are used to derive heat generated when incident light passes through the light modulator. The liquid crystal layer is disposed between the first light modulating portion and the second light modulation portion. The liquid crystal layer is configured to modulate the incident light by deflection of liquid crystal molecules. The light modulator provided by the |
