Problems solved by technology

At present, display panels usually have front-facing cameras and other devices in the display area. In order to realize a full screen, it is often necessary to open light-transmitting areas such as through holes or blind holes on the display panel to realize the settings of cameras and other equipment. Due to the structural limitation of the light-transmitting area of ​​the panel, water and oxygen can easily invade the light-transmitting area, causing device failure in the display panel

Abstract

The invention discloses a display panel and a display device. The display panel comprises a substrate, an array layer and a light-emitting device layer which are arranged in a stacked mode, and the substrate comprises a first substrate body, a composite inorganic layer and a second substrate body which are arranged in a stacked mode in the film layer stacking direction of the display panel; an opening penetrating through the array layer and the light-emitting device layer and extending to the second substrate is formed in the light-transmitting area, the light-emitting device layer comprises an organic light-emitting layer, and the organic light-emitting layer comprises a main body part arranged in the display area and an extending part falling into the opening. In other words, the extending part in the organic light-emitting layer in the hole is in contact with the second substrate. In order to prevent water and oxygen from being transmitted to a display area through the extension part in contact with the second substrate, the inner film layer of the display panel is prevented from deteriorating, and the display device is prevented from losing efficacy. Therefore, the composite inorganic layer comprises at least one water and oxygen blocking layer which can prevent water and oxygen from intruding into the second substrate from the light-transmitting area, so that the water and oxygen blocking capability of the display panel is improved, and the packaging effect of the display panel is ensured.

Description

technical field [0001] The invention belongs to the technical field of electronic products, and in particular relates to a display panel and a display device. Background technique [0002] With the gradual escalation of user needs, smart display devices are rapidly developing in the direction of full screens. Compared with ordinary displays, full screens have a larger screen-to-body ratio and ultra-narrow bezels, which can significantly improve the display effect. and received widespread attention. At present, display panels usually have front-facing cameras and other devices in the display area. In order to realize a full screen, it is often necessary to open light-transmitting areas such as through holes or blind holes on the display panel to realize the settings of cameras and other equipment. Due to the structural limitation of the light-transmitting area of ​​the panel, water and oxygen can easily invade into the light-transmitting area, resulting in failure of devices...
