Problems solved by technology

When the laser beam is used to melt the glass powder, it is easy to cause the melting speed of the glass powder in the center of the packaging area to be inconsistent with the melting speed of the glass powder at the edge of the packaging area, resulting in stress in the packaging area, which easily causes defects such as cracks in the packaging material. cause package failure

Abstract

The invention discloses an organic light-emitting display panel and a production method thereof and a display device. The organic light-emitting display panel comprises a display area and a packagingarea surrounding the display area; in the display area, multiple organic light-emitting devices are arranged between a substrate and a packaging cover plate, and in the packaging area, a packaging material used for adhering and sealing the substrate and the packaging cover plate is arranged between the substrate and the packaging cover plate; the substrate comprises a substrate body, a metal layerlocated in the packaging area, a first insulation layer located between the metal layer and the packaging material and multiple diffuse reflection protrusions also located between the metal layer andthe packaging material, and particularly, the diffuse reflection protrusions are located on one side of the first insulation layer and away from the packaging cover plate. By the arrangement, energyof laser beam transmission can be evenly distributed in the packaging area, melting rate of glass powder in the center of the packaging area and glass powder at the edge of the packaging area is relatively uniform, stress caused by nonuniform melting rate of the glass powder in the center of the packaging area and the glass powder at the edge of the packaging area can be reduced, and reliability of the organic light-emitting display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an organic light emitting display panel, a display device and a manufacturing method thereof. Background technique [0002] Organic Light Emitting Display (OLED) panels use organic materials that can emit light, and have excellent properties such as ultra-thin, fast response, wide viewing angle, light weight, low power consumption, and high brightness. One of the most promising technologies. [0003] The OLED device itself is very sensitive to water vapor and oxygen, and OLEDs exposed to water vapor and oxygen will have poor working stability and reduced lifespan. Therefore, the packaging of the organic light emitting display panel requires water vapor and oxygen barriers. [0004] One form of packaging for organic light-emitting display panels is cover-type packaging, such as figure 1 The schematic diagram of the encapsulation process between the substrate and the ...
