Abstract

The organic light emitting diode display panel provided by the invention comprises the following structures: a substrate; an array layer which is arranged on the substrate, wherein a special groove isformed in the surface of the side, away from the substrate, of the array layer; an electroluminescent layer, wherein the electroluminescent layer is arranged on the array layer; a thin film packaginglayer which is arranged on the electroluminescent layer and covers the electroluminescent layer, wherein the thin film packaging layer extends into the special groove so as to fill the special grooveand a mutually meshed special structure is formed at the position of the special groove. Therefore, in the bending process of the organic light emitting diode display panel, the array layer and the thin film packaging layer are not easy to peel off with the help of the meshing effect between the special structures, so that external water and oxygen are not easy to invade the electroluminescent layer, and the service life of the organic light-emitting diode display panel is further prolonged.

Description

technical field [0001] The present application relates to the display field, in particular to an organic light emitting diode display panel. Background technique [0002] At present, organic light-emitting diode devices have the advantages of light weight, wide viewing angle, fast response time, low temperature resistance, and high luminous efficiency compared with traditional liquid crystal displays, so they have been regarded as the next generation of new display technology in the display industry. [0003] In recent years, current organic light emitting diode devices mainly include substrates, array layers, electroluminescent layers, and thin-film encapsulation layers. The thin-film encapsulation layer often adopts an inorganic / organic / inorganic overlapping film structure, and the inorganic film layer acts as a barrier against water and oxygen. layer, and the organic film layer is used as a buffer layer to slow down the internal stress of the inorganic film layer and enha...
