BACKLIGHT DEVICE Russian patent published in 2017 - IPC G02F1/13357 

Abstract RU 2624598 C2

FIELD: lighting.

SUBSTANCE: transparent and diffusing masking elements (120, 121, 122) mask individual light sources (110, 111, 112) and diffuse the light back into the light guide (101). The absorbent elements (130, 131, 132) or the light reflecting elements are arranged so that they surround the light sources (110, 111, 112) to avoid generation of bright spots or rings around the light sources (110, 111, 112).

EFFECT: thin backlight design and high uniformity of light emitted by the backlight device.
