Organic luminous component and manufacturing method therefor

Abstract

The invention provides an organic luminous component together with the related processing method, which is characterized in that on a transparent substrate, at least one dielectric material with low refractive index and a transparent conducting material or a dielectric material with high refractive index are in vapor deposition in order to form a single-layered gradual changing layer of refractive index on the transparent substrate and the gradual changing layer of refractive index is provided with a transparent conducting layer as anode that is provided with an organic luminous layer which is provided with a metal conducting layer as cathode. As the refractive index value of upper surface and lower surface of the gradual changing layer of refractive index is the same with that of the transparent substrate and the transparent conducting layer, and the refractive index value of lower surface of the gradual changing layer of refractive index increases following the vertical height and reaches the refractive index value of upper surface of the gradual changing layer of refractive index, the refractive index value of gradual changing layer of refractive index is a smoothing and continuous refractive index to effectively reduce interface reflection and improve luminous efficiency, luminous brightness, and prolong the service life of the organic luminous component.

Description

technical field [0001] The invention relates to an organic light-emitting component and a manufacturing method thereof, in particular to an organic light-emitting component with a single-layer refractive index gradient layer and a manufacturing method thereof. Background technique [0002] In 1987, C.W.Tang and S.A.Vanslyke developed a double-layer amorphous structure organic light-emitting component (U.S. Pat. No. 4,885,211) by thermal evaporation technology. The luminous efficiency of the organic light-emitting component directly affects the luminous brightness and service life of the component. [0003] As shown in the prior art (U.S.Pat.No. 6,586,876), two kinds of dielectric materials with high and low refractive index are used to form a variety of mixed materials under different volume fractions, and the refractive index is between 1.52 to 1.9. These mixed materials are sequentially deposited between the glass substrate and the transparent conductive layer to obtain a...

Problems solved by technology

[0005] Among them, r m，m+1 is the interface reflection coefficient (Fresnel reflection coefficient) between the mth layer and the m+1th layer, is the optical complex refractive index ( n ~ = n - ik ) , And n is the refractive index (refractive index), k is the extinction coefficient (extinction coefficient), too high interface reflection will affect the external luminous efficiency of the module

Although this kind of multilayer structure with refractive index distribution can effectively improve the luminous efficiency of organic light-emitting components, the multilayer structure is not only quite complicated to manufacture, but also increases the manufacturing cost.
