Problems solved by technology

[0007] Therefore, the object of the present invention is to provide a new method and device for sealing an organic light-emitting diode, to improve the problem that the sealing operation becomes complicated and the manufacturing cost increases due to the special shape of the cover. The sealing method and the sealing device are worked hard, and by using a flat plate-shaped sealing plate with a simple structure instead of the cover on the sealing member, the function that the cover should have is not damaged, and the sealing operation is simple and the manufacturing cost is low.

Embodiment Construction

[0081] Various embodiments of the sealing structure, sealing method and sealing device of the organic light-emitting diode of the present invention will be described below with reference to the accompanying drawings. figure 1 is a flow chart illustrating the organic light-emitting diode sealing method of the present invention, showing an upside-down state in relation to the sealing device. exist figure 1 The process of the organic light emitting diode 3 is to form an organic light emitting layer and a metal electrode layer on the bottom of the glass substrate 2 in a vacuum chamber (not shown) for manufacturing the organic light emitting diode device. The sealing process is performed by moving the substrate 2 into the sealing vacuum chamber 1 which is a part of the vacuum chamber with the organic light emitting diode 3 facing downward. The sealing plate 4 for sealing the organic light emitting diode 3 is made of transparent glass, but as will be described later, other material...

Abstract

The present invention provides one kind of sealing structure, sealing method and sealing for organic LED. The sealing plate with simple structure for sealing member has the same function as a protecting cover and the sealing job is simple and low in cost. To reach the said aim, the sealing plate of transparent glass has several pre-formed raised strips, which are combined with the base plate to enclose the organic LED. Adhesive is painted into grooves formed by the sealing raised strips to adhere the sealing plate to the base plate and maintained in the grooves to seal the LED without contact and damage to the LED.

Description

technical field [0001] The present invention relates to a new sealing structure for organic light-emitting diodes, which uses a sealing plate to seal organic light-emitting diodes in order to protect organic light-emitting diodes formed on a substrate from contact with oxygen or moisture contained in the air, Sealing method and sealing device. Background technique [0002] Organic light-emitting diodes used in organic light-emitting diode displays are thin, all-solid-state flat-panel light-emitting display elements. Because they do not require backlights, consume less power, have high reliability, and can display high-definition, high-contrast, high-quality images, in recent years Come to attract attention in the display field. The method of organic light-emitting diodes is to pre-form a transparent electrode that will become an anode when it is completed on an indium tin oxide (Indium Tin Oxide, ITO) glass substrate, evaporate an organic thin film on it to form a light-emi...
