Problems solved by technology

[0004] However, there are many defects in the existing method. On the one hand, the water and oxygen barrier of the flexible substrate 1 is poor, and it is easily corroded, which leads to the problem of weak durability; on the other hand, the current inorganic ceramic film 4 is made by sputtering ( Sputtering) and plasma enhanced chemical vapor deposition (PECVD) technology, this process will cause damage to the device layer (such as thin film transistor layer 2 and organic light emitting layer 3)
The above two problems affect the performance and lifespan of OLED display devices

Abstract

The invention discloses a display device and a manufacturing method thereof. The manufacturing method of the display device includes providing a substrate; forming a first inorganic film layer on the substrate; forming a device layer on the first inorganic film layer; A thin-film encapsulation layer is formed on the device layer, and the thin-film encapsulation layer includes alternately laminated organic film layers and second inorganic film layers; wherein, the first inorganic film layer and the second inorganic film layer are spin-coated with a precursor solution and obtained by solidification. This method has simple manufacturing process and low cost, can improve the water and oxygen barrier performance of the substrate, reduce the film stress of the thin film packaging layer, and improve the durability of the substrate and the overall display device.

Description

technical field [0001] The invention relates to the display field, in particular to a display device and a manufacturing method thereof. Background technique [0002] With the development of the information society, people's demand for display devices is increasing day by day. Flexible display devices are becoming more and more popular due to their thinness, bendability or even curling, and good mechanical properties. At present, flexible display devices are more and more widely used in daily life. Flexible display devices include flexible liquid crystal displays (LCDs) and flexible organic light emitting diode displays (OLEDs). Flexible display devices are usually made on flexible carriers. Due to their unique bendable characteristics, flexible display devices have many special user experiences, and also bring great challenges to their design and production. [0003] Such as figure 1 As shown, the current encapsulation technology of flexible OLED display devices mostly ...
