Method and device for sealing with frit and frit

Abstract

The embodiment of the invention provides a method and a device for sealing with frit and frit. The light absorption of the frit is improved, the reject ratio of an OLED substrate is reduced, and the quality of the OLED substrate is improved. The frit comprises sealing glass and filler, wherein the filler comprises an inorganic quantum dot material. The embodiment of the invention relates to the field of sealing technology.

Description

technical field [0001] The invention relates to the field of sealing technology, in particular to a sealing method, device and glass frit using glass frit. Background technique [0002] OLED (Organic Light-Emitting Diode), as a new type of flat-panel display, has the characteristics of active luminescence, high luminance, high resolution, wide viewing angle, fast response, low energy consumption and flexibility. , has received more and more attention, and has become a next-generation display technology that may replace liquid crystal displays. [0003] Organic layer materials that are extremely sensitive to water vapor and oxygen exist in current OLED devices, which greatly reduces the lifespan of OLED display devices. In order to solve this problem, in the prior art, various materials are mainly used to isolate the organic layer material of the OLED from the outside world, so that the sealing performance can be achieved: the water vapor content is less than 10 -6 g / m 2 / ...

AI Technical Summary

Problems solved by technology

However, materials such as Cu and Fe have limited ability to absorb light. In the process of melting the sealing glass, a high-power laser needs to be applied, which causes the upper and lower glass substrates to be heated too high and prone to the risk of cracking.
