ORGANIC ELECTROLUMINESCENT DIODE AND DIODE PANEL WITH ANTI-REFLECTIVE COATING CONDUCIVE TO THE EMISSION OF LIGHT

摘要

The invention relates to a diode comprising an electroluminescent organic layer (6), interposed between a lower electrode and a partially-transparent and semi-reflective upper electrode which itself comprises a transparent conductive sub-layer (4) and a metallic sub-layer (3) for distribution of current, for example, an opaque grille. An anti-reflective dielectric layer (2) is deposited on the grille to improve the contrast of the emission in ambient light, which, in an advantageous embodiment, is embodied to optimise the semi-reflective properties of the upper electrode which permits an improvement in the passage of emitted light by means of the effect of optical cavities.
