Abstract

The invention discloses a display panel and a manufacturing method thereof. According to the display panel, a hollow part is arranged on a first inorganic packaging layer, a structure for filling andpackaging the anti-cracking piece in the hollow part is combined, and the stress of the packaging film of the display panel in the cutting process or the bending process is well dispersed, therefore,the tearing risk of the inorganic layer part in the packaging film is reduced, the packaging performance of the packaging film is improved, the narrow bezel of the OLED display panel is better facilitated. In addition, the manufacturing method of the display panel adopts a mature process for manufacturing the hollow part and the packaging anti-cracking piece, and the manufacturing method is suitable for batch manufacturing.

Description

technical field [0001] The present application relates to the technical field of display panels, in particular to a display panel and a manufacturing method thereof. Background technique [0002] With the development of display technology, OLED display panels have been widely used for their advantages of fast response speed, wide temperature range, self-illumination, and flexible display. With the increasing market demand, the research and development of flexible OLED And production has become a hot field for the development of the display industry at present, among which thin film packaging technology is the key technology to ensure the reliability of flexible OLED display panels. Usually flexible packaging films are composed of inorganic / organic / inorganic laminated films, so during the cutting process and bending (bending) process, the inorganic film layer at the edge of the panel (panel border) has the risk of cracking, causing Cracks or even peeling off of the encapsula...
