Problems solved by technology

[0004] However, the inventors of the present application have found that, since the glass glue is viscous, the glass glue will flow outward after being applied to the packaging substrate, which will cause burrs on the edge of the glass glue
When irradiating the glass glue with laser, since the laser can only irradiate the glass glue in the bonding area, the glass glue in the area where the burr is located cannot be cured, and thus cannot play the role of bonding the display substrate and the packaging substrate, resulting in Waste of glass glue; at the same time, the part between the adjacent burrs on the outer edge of the glass glue is more susceptible to the invasion of external water vapor and oxygen, which seriously affects the life of the OLED display device

Abstract

The invention discloses a packaging substrate and a manufacturing method thereof, an OLED display device and a manufacturing method thereof, relates to the technical field of display, and can prevent an outer side edge of glass cement coated on the packaging substrate from generating burrs. The packaging substrate includes a substrate, the substrate includes a bonding area used for coating glass cement, the packaging substrate also includes a first retaining wall located on the substrate, and the first retaining wall is arranged along an outer side edge of the bonding area and is used for stopping the glass cement coated on the bonding area from flowing outwards. The packaging substrate provided by the invention is used for preventing outside moisture and oxygen from entering an OLED display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a packaging substrate and a manufacturing method thereof, an OLED display device and a manufacturing method thereof. Background technique [0002] Organic Light Emitting Display (OLED display for short) has gradually become the main development trend of display devices due to its advantages of self-luminescence, high brightness, high response speed, thinness, full color, and no viewing angle difference. [0003] The OLED display device includes a display substrate, on which a cathode, an anode, and an organic functional layer located between the cathode and the anode are arranged, wherein the organic functional layer is very sensitive to water vapor and oxygen, and is easily oxidized after contacting with water vapor or oxygen. lead to failure, thereby affecting the display effect of the OLED display device. In the prior art, the display substrate is packaged mainly through the...
