Embodiment Construction

[0026]Hereinafter, the present invention will be described in detail by explaining embodiments of the invention with reference to the attached drawings.

[0027]First, a Joule heat encapsulating apparatus according to the present invention is an apparatus for performing an encapsulating operation by using Joule heat generated when a current flows in a conductor, and it may have a structure as shown in FIGS. 1 thru 3, for example.

[0028]FIG. 1 is an exploded perspective view of a Joule heat encapsulating apparatus according to an embodiment of the present invention; FIG. 2 is plan view of the Joule heat encapsulating apparatus of FIG. 1; and FIG. 3 is a sectional view taken along a line A-A of FIG. 2.

[0029]Referring to FIGS. 1 thru 3, the Joule heat encapsulating apparatus according to the present embodiment includes a stage 10 to which a panel 100 is mounted, and a cap 20 which covers the stage 10 so as to seal around the panel 100. In other words, a sealed space S (refer to FIG. 3) hou...

Abstract

In a Joule heat encapsulating apparatus and an encapsulating method using the same, a panel is mounted on a stage, the panel including a thermal-hardening type sealant for surrounding and sealing a display unit formed between a first substrate and a second substrate, a heat-generating wiring overlapping the thermal-hardening type sealant, and an electric current application wiring connected to the heat-generating wiring. A cap is employed to form a sealed space, in which the panel is arranged, between the stage and the cap. An exhaustion mechanism for exhausting air in the sealed space, and a power applying mechanism connected to the electric current application wiring for supplying a current to the heat-generating wiring, are provided. As a result, a stable encapsulating structure which prevents permeation of oxygen or moisture may be easily formed.

Description

CLAIM OF PRIORITY[0001]This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C. §119 from an application earlier filed in the Korean Intellectual Property Office on Aug. 18, 2010 and there duly assigned Serial No. 10-2010-0079851.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to an encapsulating apparatus for encapsulating a display unit of a flat panel display device, and more particularly, to an encapsulating apparatus for performing encapsulation by using Joule heat.[0004]2. Description of the Related Art[0005]Flat panel display devices, e.g., an organic light-emitting display device, may be fabricated so as to be thin and flexible due to operating properties, and thus a variety of research is being conducted thereon.[0006]However, such flat panel display devices have a property such that a display unit thereof is deteriorated by permeation of oxygen or moisture. Therefore, t...
