Problems solved by technology

[0005] For OLED substrates with touch functions, it is usually necessary to prepare touch electrodes and sensing electrodes on the substrates on which OLED devices have been formed. However, the integration of such substrates is relatively low and the thickness is relatively thick, which is not conducive to thinner display panel

Abstract

The invention provides an organic electroluminescence diode substrate and a preparation method and a display apparatus thereof, and belongs to the field of display technology. The organic electroluminescence diode substrate includes a substrate, an organic electroluminescence unit arranged on the substrate, and N groups of film sets which are arranged on the organic electroluminescence unit. N is an integer which is equal to or greater than 2. Each group of film set includes an inorganic film layer and an organic film layer which are successively arranged away from the direction of the organic electroluminescence unit, and one layer of the organic film layers is provided with a plurality of first grooves, and the other layer of the organic film layers is provided with a plurality of second grooves. The plurality of first grooves and the plurality of second grooves are intersected in orthographic projection on the substrate. Each first groove is filled with a first lead. Each second groove is filled with a second lead. According to the invention, the organic electroluminescence diode substrate is suitable for flexible display panels.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to an organic electroluminescence diode substrate, a preparation method thereof, and a display device. Background technique [0002] In the field of optoelectronic display technology, Organic Light Emitting Diode (OLED) has many advantages such as active light emission, high brightness, high contrast, ultra-thin, low power consumption, large viewing angle and wide operating temperature range. An advanced new flat panel display device with a wide range of applications. [0003] However, due to the inherent characteristics of organic materials, it is easy to absorb water and oxygen, and it is easy to wear and deteriorate after being eroded by water and oxygen, which greatly affects the life of the device. Therefore, OLED devices have high requirements for packaging. [0004] At present, the encapsulation technology of OLED devices is becoming more and more mature, includ...
