OLED (organic light emitting devices) screen body capable of preventing lead corrosion and OLED screen body packaging method

Abstract

The invention provides a method for packaging an OLED (organic light emitting diode) screen body comprising the following steps: a) preparing packaging sheets, arranging a plurality of through holes on the packaging sheets, forming a plurality of packaging holes; b) dispensing on the packaging sheets, dispensing zone being arranged at one side of the through hole which is housed by a notch; c) preparing the substrate, preparing an anode layer, an organic layer and a cathode layer on the substrate; d) under the inert gas or vacuum environment, packaging the packaging sheets on the substrate by using a packaging glue; and e) incising along an edge of the through hole of the packaging sheet far away from a packaging pit, and obtaining the OLED screen body. By using the OLED screen body with the packaging structure, liquid oxygen can be effectively prevented to be sealed in a corresponding space in a packaging process, thus leads are prevented from electrocorrosion, and the service life of the screen body is prolonged.

Description

technical field [0001] The invention relates to the technical field of organic light-emitting displays, in particular to an OLED screen body capable of preventing corrosion of lead wires and a method for encapsulating the OLED screen body. Background technique [0002] With the development of multimedia technology and the advent of the information society, the performance requirements of flat panel displays are getting higher and higher. In recent years, three new displays have emerged: plasma displays, field emission displays, and organic electroluminescent displays, all of which have made up for the shortcomings of cathode ray tubes and liquid crystal displays to a certain extent. Among them, organic electroluminescent displays have a series of advantages such as self-illumination, low-voltage DC drive, full curing, wide viewing angle, and rich colors. Compared with liquid crystal displays, organic electroluminescent displays do not require a backlight source, have a large...

Problems solved by technology

[0004] In the prior art, in the way of electrical connection, the electrical connection space of the screen body is completely exposed on one side, and after the IC or FPC is bonded, it is covered with various glues. The problem with this is that the covering During the process of various glues, water and oxygen may be sealed into the corresponding space at the same time, and the lead wires used for conducting electricity on the screen are not only small, but also easily corroded by water and oxygen. During use, the water and oxygen in the sealed space may cause Galvanic Corrosion of Leads
