OPTICALLY ADDRESSED SPATIAL LIGHT MODULATOR AND METHOD Russian patent published in 2011 - IPC G02B26/02 B81B7/02 

FIELD: physics.

SUBSTANCE: optical device has a first electrode layer. An electrically insulating first barrier layer is placed over the first electrode layer. A photoconductive layer is placed over the first barrier layer. A carrier confining layer is placed over the photoconductive layer, where said carrier confining layer defines a volume and has a plurality of carrier traps distributed over the entire said volume. An electrically insulating second barrier layer is placed over the carrier confining layer. A light blocking layer is placed over the second barrier layer for blocking light of a selected wavelength band. A reflective layer is placed over the light blocking layer for reflecting light within the selected wavelength band. A birefringent or dispersive layer is placed over the reflective layer. An optically transmitting second electrode layer is placed over the birefringent or dispersive layer.

EFFECT: obtaining large display screens with good resolution, brightness and fast response.
