HIDDEN ORGANIC OPTOELECTRONIC DEVICES WITH A LIGHT SCATTERING LAYER

摘要

An optoelectronic device (100) comprising at least one optoelectronic active region (101) comprising at least a rear electrode (102) and a front electrode (103) between which an organic optoelectronic material (104) is sandwiched, said rear electrode (102) being reflective, and a cover layer (105) arranged in front of said front electrode (103). The cover layer (105) comprises a material with light-scattering particles (110) of a first material dispersed in a transparent matrix (111) of at an least partly hydrolyzed silica sol. Due to the highly scattering propertied of the cover layer, the device is essentially concealed behind the cover layer when not in its operative state.
