METHOD OF MAKING OPTICAL FILTER MATRICES FOR LIQUID CRYSTAL DISPLAY AND DEVICE FOR REALISING SAID METHOD Russian patent published in 2010 - IPC G02F1/13 

FIELD: physics; optics.

SUBSTANCE: invention relates to indicator equipment. In the method primary colours are generated using phase Fresnel lenses made from exposed and non-exposed sections of a photopolymer. The invention involves depositing a transparent layer, depositing a photopolymer layer, exposing the photopolymer layer with simultaneous evaporation of narrow strips of a non-transparent layer. All operations can be carried out on a fixed substrate. The device has a writing head with a UV radiation source and 3 infrared radiation sources.

EFFECT: possibility of cutting the number of operations when making optical filter matrices and reducing expenses of making the display.
