Abstract

The invention discloses a display panel and a fabrication method. The display panel comprises a substrate, a display component and a thin film package layer, wherein the display component is arranged on the substrate, the thin film package layer is arranged on the display component and comprises at least one first package material layer and at least one second package material layer, the refractive indexes of the first package material layer and the second package material layer are different, a plurality of grooves are formed in the at least one first package material layer, and the grooves are filled with the second package material layer arranged above the first package material layer provided with the plurality of grooves. Through the technical scheme, the luminous efficiency of the display panel is improved, and the service lifetime of the display panel is prolonged.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a display panel and a manufacturing method thereof. Background technique [0002] With the rapid growth of demand for portable mobile devices and wearable devices, flexible display technology has been greatly developed. Among the display technologies that can realize flexible display, OLED (Organic Light-Emitting Display, organic light-emitting diode display) is considered to be the most promising flexible display technology because of its advantages such as bending resistance, fast response speed, wide viewing angle, and light weight. One of the promising technologies. [0003] OLED devices are very sensitive to water vapor and oxygen, and OLED devices exposed to water vapor and oxygen will have poor working stability and reduced lifespan. Therefore, adopting an effective packaging structure to prevent the intrusion of water vapor and oxygen can prol...
