Abstract

The invention discloses a display panel, a packaging method thereof, and a display device, and belongs to the field of display technology. The method includes: providing a base substrate; sequentially forming a thin film transistor TFT, a light-emitting device, and a first inorganic barrier layer on the base substrate; forming an organic material layer doped with a foaming agent; performing a foaming treatment on the organic material layer doped with a foaming agent to form a bubble structure inside the organic material layer to obtain an organic scattering layer; The side of the scattering layer away from the base substrate forms a second inorganic barrier layer. The invention solves the problem in the related art that the light coupling efficiency of the OLED display panel is low, resulting in low light extraction efficiency of the OLED display panel. The invention is used for packaging of display panels.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a packaging method thereof, and a display device. Background technique [0002] Since the organic light-emitting material in the organic light-emitting diode (Organic Light-Emitting Diode, OLED) device contacts with water and oxygen, it will affect the light-emitting effect of the organic light-emitting material, and then affect the quality and service life of the OLED device. Therefore, the packaging of the OLED device very important. [0003] In related technologies, flexible OLED devices are usually packaged with laminated films to obtain an OLED display panel. The OLED display panel obtained after packaging includes: a base substrate, a thin film transistor (ThinFilm Transisto, TFT) sequentially arranged on the base substrate, An OLED device, an inorganic barrier layer, and an organic buffer layer and an inorganic barrier layer that are stacked and staggere...
