HIDDEN ORGANIC OPTOELECTRONIC DEVICES HAVING LIGHT-SCATTERING LAYER Russian patent published in 2013 - IPC H05B33/22 H01L51/52 

FIELD: physics.

SUBSTANCE: optoelectronic device (100) has at least one optoelectronic active region (101) having at least a rear electrode (102) and a front electrode (103) between which an organic optoelectronic material (104) is placed, said rear electrode (102) being reflective, and a protective layer (105) is placed in front of said front electrode (103). The protective layer (105) contains a material with light-scattering particles (110) of a first material dispersed in a transparent matrix (111) of at least partially hydrolysed silica sol.

EFFECT: improved scattering properties of the protective layer of the device virtually enables its concealment behind the protective layer when not in its operating state.
