Abstract

The invention relates to the technical field of illumination and display, and discloses a light-emitting panel, a preparation method thereof and a light-emitting device. The light-emitting panel is provided with a light-emitting area and an isolation area adjacent to the light-emitting area. The light-emitting panel comprises a substrate and a barrier structure. The barrier structure is arranged on one side of the substrate and located in the isolation region and comprises a first isolation pattern, a second isolation pattern, a third isolation pattern and a fourth isolation pattern which are sequentially stacked, and the first isolation pattern is closer to the substrate than the fourth isolation pattern; the orthographic projection of the first isolation pattern on the substrate is located in the orthographic projection of the second isolation pattern on the substrate, and the orthographic projection of the third isolation pattern on the substrate is located in the orthographic projection of the fourth isolation pattern on the substrate. The orthographic projection of the third isolation pattern on the substrate is located in the orthographic projection of the second isolation pattern on the substrate. The blocking structure of the light-emitting panel forms a double-layer I-shaped structure, and the blocking effect is good.

Description

technical field [0001] The present disclosure relates to the technical field of lighting and display, and in particular, to a light-emitting panel, a method for preparing the light-emitting panel, and a light-emitting device including the light-emitting panel. Background technique [0002] With more and more requirements for special-shaped light emission, the shape of the light-emitting area is different from the regular rectangular light-emitting area. It is necessary to design the isolation part to block and isolate the light-emitting functional layer and the cathode to achieve light emission in the special-shaped area; however, the current isolation part The isolation effect is not ideal. [0003] It should be noted that the information disclosed in the above background section is only for enhancing the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to those of ordinary skill in...
