DEFINITION

Classification: 349/25

With photoconductive layer (e.g., spatial light modulator (SLMs)):

(under subclass 24) Subject matter wherein the liquid crystal material exhibits an optical property change when an electrical field is produced across the liquid crystal in response to the application of light to corresponding areas of a photosensitive layer.

(1) Note. Included here are photoconductors and photodiodes.
