Abstract

The invention provides a display substrate, a manufacturing method, and a display device, which relate to the field of display technology, can reduce the probability of a frame sealing glue falling off and breaking, and solve the problem that a display device is corroded by water and oxygen caused by a frame sealing glue falling off and breaking. A display substrate, the display substrate is provided with a functional film layer, and at least one layer of the functional film layer includes a protruding array on the side away from the display substrate; wherein, when the display substrate is boxed with another display substrate, the protruding array corresponds to The protrusions are used to embed the sealant between the display substrate and another display substrate. The embodiments of the present invention are used in the manufacture of display devices.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, a manufacturing method and a display device. Background technique [0002] With the advancement of technology, organic light emitting diodes (English full name: Organic Light Emitting Display, abbreviated: OLED) are more and more widely used in daily life. In the technology of flat panel display and planar light source, the bonding of two pieces of flat glass is a very important technology, and its encapsulation effect will directly affect the performance of the device, which makes it more important to control the quality of the encapsulation effect of OLED display devices. important. [0003] Usually, the packaging of OLED display devices is to use the sealing glue to bond the substrates on both sides; here we take the OLED display device packaged with glass glue (English full name: Frit) packaging technology as an example, which is to make the Frit materi...
