Embodiment 1

[0039] figure 1 It is a top view of a display panel disclosed in Embodiment 1 of the present invention, such as figure 1 As shown, the display panel has a preset hole 101 for setting a camera module, an area 102 between the preset hole and the effective display area, and an effective display area 103 . figure 1 The shaded pattern filled area in is the area 102 between the preset hole and the effective display area.

[0040] The devices provided in the above-mentioned camera module include but are not limited to at least one of a distance sensor, a light sensor, a camera and an infrared sensor. The preset hole 101 in this embodiment is circular, which is not limited in the present invention. The preset hole 101 may also be a quadrilateral or other shapes, which can be set by those skilled in the art as required.

Abstract

The invention provides a display panel, a manufacturing method thereof, and a display device. The display panel comprises: a substrate; a barrier layer which is formed on the first side of the substrate, and the patterned barrier layer is a plurality of barrier wall bodies which are arranged at intervals and distributed in a concentric circle mode with the preset hole as the center; an organic membrane group which is formed in the side, deviating from the substrate, of the barrier layer, wherein a first barrier through groove is exposed out of the surface of the barrier layer; a first buffer layer which is formed on one side, deviating from the barrier layer, of the organic film group, wherein the a second barrier through groove exposes the side wall of the first barrier through groove andthe surface of the barrier layer; a first light-emitting layer which is formed on the surface of one side, deviating from the organic film group, of the first buffer layer; and a packaging layer which is formed on the side, deviating from the first buffer layer, of the first light-emitting layer, wherein the packaging layer covers the side wall of the second barrier through groove, the side wallof the first barrier through groove and the surface of the barrier layer. According to the invention, OLED devices around the holes in a perforated screen are effectively prevented from being invadedby water and oxygen to fail, and the service life of the display panel is prolonged.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the development of organic light-emitting display devices, the continuous reduction in weight and volume has expanded the application range of organic light-emitting display devices. With the current increasing demand for large screen-to-body ratio of display devices, many manufacturers adopt the technology of punching holes in the screen to accommodate essential front functional components such as cameras and sensors. Therefore, the punching technology of display panels has received widespread attention. [0003] Since organic light-emitting displays are very sensitive to oxygen and water vapor, water and oxygen infiltrating into the light-emitting layer from the perforated area will seriously affect the luminous life of the device. Therefore, after the disp...
