Abstract

The invention provides a display device, a display panel and a preparation method thereof. The display panel comprises a substrate and a thin film packaging layer arranged on the substrate, wherein the display panel comprises a display area and a non-display area, and the thin film packaging layer comprises an organic layer and at least one dam. The organic layer covers the display area, the at least one dam is arranged on the non-display area and used for preventing the organic layer from overflowing, and an uneven structure is arranged on the surface of the at least one dam. An uneven structure is arranged on the at least one dam, the adhesion area of the at least one dam and the thin film packaging layer is increased, overflowing of the organic layer is better blocked, packaging failures caused by erosion of water oxygen to electronic elements are further reduced, and then the service life of the display panel is prolonged.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a display device, a display panel and a preparation method thereof. Background technique [0002] The use and fabrication of flexible displays has gained popularity in recent years. However, the encapsulation layer in the display panel will fail due to moisture and oxygen easily invading the components, and even cause the components to be corroded, reducing the service life of the display device. Therefore, the research on flexible display panel packaging has been paid attention to. [0003] In the encapsulation layer of the display panel, the inkjet printing process is generally used to prepare the organic layer in the encapsulation layer, and at the same time, a dam is also provided to avoid problems such as poor encapsulation effect caused by the overflow of the organic ink material. However, during the bending process of the flexible panel, the design of the traditional dam is pr...
