Problems solved by technology

Because the light-emitting devices of OLED display panels are very sensitive to water vapor and oxygen, they will be corroded and damaged when exposed to the atmospheric environment. Therefore, the packaging of OLED display panels is very important, but the packaging effect of existing OLED display panels is poor.

Abstract

The invention provides a display device, a display panel and a packaging method of a display substrate, and relates to the technical field of display. The packaging method comprises that: a display substrate is provided, the display substrate comprises a driving backboard and a light-emitting function layer which are arranged in a laminated mode, and the light-emitting function layer comprises a plurality of light-emitting units distributed in an array mode and a pixel definition layer for separating the light-emitting units; at least one packaging layer is formed on the side, deviating from the driving backboard, of the light-emitting function layer, each packaging layer comprises a first inorganic layer, an organic layer and a second inorganic layer, the organic layer is located on the side, deviating from the driving backboard, of the first inorganic layer, and the organic layer is provided with a through hole right opposite to the pixel definition layer; and the second inorganic layer is located on the side, away from the light-emitting function layer, of the organic layer and connected with the first inorganic layer through the through hole. According to the display device, the display panel and the packaging method of the display substrate, stripping of the packaging layer can be avoided, and the packaging effect is improved.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a packaging method for a display device, a display panel, and a display substrate. Background technique [0002] With the development of display technologies, OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display panels have been widely used due to their advantages of high response, high contrast, and flexibility. Since the light-emitting device of the OLED display panel is very sensitive to water vapor and oxygen, it will be corroded and damaged when exposed to the atmospheric environment. Therefore, the packaging of the OLED display panel is very important, but the packaging effect of the existing OLED display panel is poor. [0003] It should be noted that the information disclosed in the above background section is only for enhancing the understanding of the background of the present disclosure, and therefore may include information that doe...
