ILLUMINATION SYSTEM AND LIQUID CRYSTAL DISPLAY DEVICE USING SAID SYSTEM Russian patent published in 2014 - IPC F21S2/00 G02F1/13357 F21Y101/02 F21Y105/00 

FIELD: technological processes.

SUBSTANCE: invention relates to lighting engineering. The illumination system comprises a light-emitting part (1), having light sources configured to emit light beams at different dominant wavelengths, and an image-forming optical system (3), having microlenses (3a) configured to focus the light beams emitted by the light-emitting part (1). The illumination system is configured to illuminate a liquid crystal panel with light beams passing through the image-forming optical system (3). The liquid crystal panel has pixels which are spaced apart by a predetermined spacing and each of which has display elements corresponding to each separate colour, and under the condition that the spacing of the pixels is denoted by P, and the image-forming optical system has a zoom factor (1/n), the light sources are spaced apart by a spacing P_1, given as P₁=n × P, and the microlenses are spaced apart by a spacing P₂, given as P₂=(n/(n+1)) × P.

EFFECT: high quality of display by suppressing non-uniformity of brightness and colour in the display screen.
