Problems solved by technology

[0003] However, the existing silicon-based OLEDs are prone to the problem of crosstalk between different sub-pixels (Crosstalk). One of the important reasons is that the hole injection layer (HIL) directly in contact with each anode is a common layer set up for the entire layer. And it has low resistivity, therefore, the HIL layer with low resistivity can easily lead to conduction between sub-pixels

Abstract

The invention relates to an organic electroluminescence structure, and a manufacturing method thereof and a display device. The organic electroluminescent structure comprises: a substrate; an anode layer which is formed on the substrate, wherein the anode layer comprises a plurality of anodes which are arranged at intervals, each anode is provided with a first surface facing the substrate and a second surface far away from the substrate, the orthographic projection of the first surface on the substrate is located in the orthographic projection of the second surface on the substrate, the orthographic projection of the first surface on the substrate is located in the orthographic projection of the second surface on the substrate, and a non-zero distance is formed between the edge of the first surface and the edge of the second surface; an organic light-emitting functional layer which is provided with a hole injection layer, wherein the hole injection layer comprises a plurality of hole injection blocks which are arranged at intervals, and each hole injection block is correspondingly formed on the second surface of one anode; and a cathode layer which is formed on one side, deviating from the anode layer, of the organic light-emitting functional layer. According to the scheme, the crosstalk problem caused by low resistivity of the hole injection layer can be improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular, to an organic electroluminescence structure, a manufacturing method thereof, and a display device. Background technique [0002] OLED (Organic Light-Emitting Diodes, Organic Light-Emitting Diodes) display technology, as a new display technology, has been widely used in smart watches, mobile phones, tablet computers, displays and other fields. Silicon-based OLED display uses monocrystalline silicon as the active driving backplane, which has excellent characteristics such as high pixel density, high integration, small size, easy to carry, good shock resistance, and ultra-low power consumption. It is one of the hotspots in current display technology research. one. [0003] However, the existing silicon-based OLEDs are prone to the problem of crosstalk between different sub-pixels (Crosstalk). One of the important reasons is that the hole injection layer (HIL) directly in c...
