Abstract

The invention provides a display device, a display panel and a preparation method thereof. The display panel includes: a substrate and a thin film encapsulation layer arranged on the substrate, wherein the display panel includes a display area and a non-display area, and the thin film encapsulation layer includes an organic layer and at least one dam, the organic layer covers the display area, at least one dam is arranged on the non-display area for blocking the overflow of the organic layer, and the surface of at least one dam has an uneven structure. In the embodiment of the present invention, by providing an uneven structure on at least one dam, the adhesion area between at least one dam and the thin film encapsulation layer is increased, the overflow of the organic layer is better blocked, and the damage caused by the erosion of water and oxygen on electronic components is further reduced. The encapsulation fails, thereby increasing the service life of the display panel.

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...
