EDGE-LIT SYSTEM FOR LIQUID CRYSTAL DISPLAYS (VERSIONS) Russian patent published in 2014 - IPC G02F1/13357 

FIELD: electricity.

SUBSTANCE: invention is related to edge-lit systems. The edge-lit system comprises an emission source in the forms of at least one light-emitting diode; the lower mirror with reflective coating; the upper reflective and diffusion film placed above the lower mirror and edge mirrors at four sides thus forming an air-filled waveguide together with the lower mirror and the upper reflective and diffusion film. The upper reflective diffusion plate is made of material with volume-diffuse scattering and reflective coating applied to its lower side; it has a number of transparent or partially transparent areas.

EFFECT: improving brightness and uniformity of lighting.
