Organic light-emitting diode display panel and manufacturing method thereof and display device

Abstract

The invention discloses an organic light-emitting diode display panel and a manufacturing method thereof and a display device. The organic light-emitting diode display panel includes a first substrate, a second substrate arranged opposite to the first substrate, an organic light-emitting element arranged between the first substrate and the second substrate, a periphery region between the first substrate and the second substrate, and a sealing layer used for packaging the organic light-emitting element between the first substrate and the second substrate in a sealing manner, wherein the sealing layer includes a supporting layer arranged on the first substrate and surrounding the periphery of the organic light-emitting element, and a bonding layer which is arranged between the supporting layer and the second substrate and covers the supporting layer. According to the manufacturing method in the invention, bubbles or a micro-crack phenomenon is not easy to occur in a packaging process of the organic light-emitting diode display panel, thereby simplifying manufacturing technology, reducing production cost, and improving the yield of organic light-emitting diode display panels.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic light emitting diode display panel, a manufacturing method thereof, and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) display has the advantages of good color contrast, high color saturation, active light emission, wide viewing angle, thinning, fast response and low power consumption, etc. popular product. [0003] However, the organic light-emitting layer and electrodes in the organic light-emitting diode device are easily damaged by the intrusion of water vapor and oxygen, resulting in reduced service life. Therefore, the organic light-emitting diode device usually needs to be sealed and packaged. [0004] In the prior art, glass frit (Frit) is generally used as the encapsulation material, and a laser-welded glass technology (Laser-Frit) is used to form an airtight sealing structure, thereby preventing water vapor and oxygen fr...
