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 present application relates to an organic electroluminescence structure, a manufacturing method thereof, and a display device. Wherein, the organic electroluminescence structure includes: a base substrate; a passivation protection layer formed on one side of the base substrate; a plurality of spaced undercuts are formed on the side of the passivation protection layer away from the base substrate, The cut portion has a first face facing the base substrate and a second face away from the base substrate, the orthographic projection of the first face on the base substrate is located within the orthographic projection of the second face on the base substrate, and the first face There is a non-zero distance between the edge of the anode and the edge of the second surface; the anode layer includes a plurality of anodes arranged at intervals, and each anode is correspondingly formed on the second surface; the organic light-emitting functional layer has a hole injection layer, holes The injection layer includes a plurality of hole injection blocks arranged at intervals, and each hole injection block is correspondingly formed on an anode; the cathode layer is formed on the side of the organic light-emitting functional layer away from the anode layer. The crosstalk problem can be improved in this scheme.
Description
technical field [0001] The present application relates to the field of display technology, and in particular, to an organic electroluminescence structure, a method for manufacturing the same, and a display device. Background technique [0002] As a new type of display technology, OLED (Organic Light-Emitting Diodes, Organic Light Emitting Diodes) display technology has been widely used in smart watches, mobile phones, tablet computers, displays and other fields. Silicon-based OLED displays have excellent characteristics such as high pixel density, high integration, small size, easy portability, good shock resistance, and ultra-low power consumption because they use monocrystalline silicon as the active drive backplane. one. [0003] However, the existing silicon-based OLED is prone to the problem of crosstalk between different sub-pixels. One of the important reasons is that the hole injection layer (HIL) in direct contact with each anode is a common layer set in the whole ...
