Problems solved by technology

For example, a micro lens array or microstructure is formed on the surface of the substrate. However, this method requires additional processing of the substrate, and problems such as adhesion and poor alignment between the substrate and the microstructure are likely to occur. , so it is less conducive to making
In addition, for example, a photonic crystal structure or a low-refractive index grating is arranged between the substrate and the light-emitting layer. However, this method also affects the uniformity of the film layer of the organic light-emitting unit, making the local electric field too large. reduce the lifetime of organic light-emitting devices

Abstract

The invention provides an organic light-emitting device including a first substrate, a second substrate arranged in parallel with the first substrate and an organic light-emitting unit arranged between the first substrate and the second substrate. The first substrate is provided with a plurality of first light-guiding microstructures, distribution density of which is between 100units / mm to 2000units / mm, wherein the first light-guiding microstructures are positioned in the first substrate and materials of the first substrate include photosensitivity materials.

Description

technical field [0001] The present invention relates to a light-emitting device, and in particular to an organic light-emitting device. Background technique [0002] Organic light emitting device (Organic light emitting device, OLED) has great application potential due to its advantages of self-illumination, no viewing angle dependence, power saving, simple manufacturing process, low cost, low temperature operating range, high response speed and full color , It is expected to become the mainstream of the lighting source for the new generation of flat panel displays. [0003] Generally speaking, an organic light-emitting device includes a first substrate, an organic light-emitting unit disposed on the first substrate, and a second substrate encapsulating the organic light-emitting unit, wherein the organic light-emitting unit includes two electrodes sandwiching a light-emitting layer. Generally speaking, when the light emitted by the light-emitting layer is emitted toward th...
