Abstract

The invention provides a thin film package structure of a display panel and a fabrication method of the thin film package structure. The thin film package structure comprises a metal / inorganic passivation layer, a buffer layer and a second passivation layer which are sequentially arranged on a top electrode of a luminous device, wherein the metal / inorganic passivation layer comprises a metal sealing mesh and a plurality of independent inorganic passivation units, the plurality of independent inorganic passivation units are arranged in the metal sealing mesh, the inorganic passivation units completely cover a luminous region of the luminous device, and the metal sealing mesh is arranged on the surface of the top electrode on which the inorganic passivation units are not covered.

Description

technical field [0001] The invention belongs to the field of flat panel display technology, and in particular relates to a thin film packaging structure of a display panel and a preparation method thereof. Background technique [0002] In the present age of the information society, the importance of the display as a visual information transmission medium is further strengthened. In order to dominate in the future, displays are trending toward lighter, thinner, lower power consumption, lower cost, and better image quality. [0003] Organic light-emitting diode (OLED) has the advantages of self-luminescence, fast response, wide viewing angle, high brightness, and thinness. However, OLED devices are sensitive to water and oxygen, and the penetration of water and oxygen has a great impact on the life of the device, so strict packaging is required. At present, the cutting-edge packaging technology is thin-film packaging. In this method, an packaging film is formed by superimpos...
