The element includes a transparent substrate; a dielectric material layer configured on the transparent substrate; a semi-transparent metal layer configured on the dielectric material layer, wherein the dielectric material layer and the semi-transparent The transparent metal layer constitutes a half-lens structure; a transparent anode is arranged on the semi-transparent metal layer; a light-emitting layer is arranged on the transparent anode; and a metal cathode is arranged on the light-emitting layer.

Description

technical field [0001] The present invention relates to a flat panel lighting device (Flat Panel Lighting Device) and a manufacturing method thereof, and in particular to a flat panel lighting device with a metal microcavity structure and a manufacturing method thereof. Background technique [0002] Among all kinds of materials that can emit light by themselves, organic electroluminescent materials are one of the most promising materials developed in recent years. The organic electroluminescent element is one of the planar light emitting elements, which not only has the advantages of simple process structure and low driving voltage, but more importantly, it can be used in plastic (Rigid Plastic) in addition to glass substrates. ) substrate and flexible (Flexible) substrate, so the organic electroluminescent element can be more widely used in optoelectronic products. [0003] For all light-emitting elements used in lighting, in addition to the requirements of high brightness...
