Problems solved by technology

However, because the Frit material is brittle after curing, it is easily damaged by force, resulting in package failure, which in turn leads to the intrusion of water and oxygen from the damaged position, corroding the pixels, and affecting the display effect.

Abstract

The invention discloses a display panel and a display device. The display panel comprises a thin film packaging screen body, a cover plate and a packaging adhesive packaging layer. The thin film packaging screen body comprises a substrate and a thin film packaging layer. The substrate and the thin film packaging layer form a closed space. A light emitting layer is arranged in the closed space. Thethin film packaging screen body is provided with a display area and a non-display area located on the outer peripheral side of the display area. The cover plate is located on the side of the thin film package layer away from the substrate. The packaging adhesive packaging layer adheres the cover plate and the substrate in the non-display area. According to the display panel, the light emitting layer of the display panel is arranged in the closed space formed by the substrate and the thin film packaging layer, and the substrate and the cover plate are adhered and packaged by the packaging adhesive packaging layer arranged in the non-display area of the thin film packaging screen body so that double-layer packaging of the light emitting layer can be realized, doubly protection of the lightemitting layer can be realized and the packaging reliability can be enhanced.

Description

technical field [0001] The invention belongs to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) display has the advantages of low cost, wide viewing angle, low driving voltage, fast response speed, rich luminous color, simple preparation process, and large-area flexible display. It is considered to have the most development prospects. One of the display technologies. [0003] Since the organic light-emitting material of the OLED display panel is susceptible to water and oxygen intrusion and affects the display effect, the packaging requirements are relatively high. In the related art, glass glue (Frit) is often used to package the array substrate and cover plate of the OLED display panel. However, since the Frit material is brittle after curing, it is easily damaged by force, resulting in package failure, which in turn leads to the intrusion of water and oxygen from the...
