Embodiment Construction

[0029] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown.

[0030] figure 1 is a plan view of an organic light emitting display device according to an embodiment of the present invention.

[0031] refer to figure 1 , the organic light emitting display device according to the embodiment of the present invention includes a substrate 110 having an image display unit 130 . Organic light emitting diodes (OLEDs) are disposed on the image display unit 130 of the substrate 110 . The substrate 110 may be a glass substrate or a flexible substrate. The organic light emitting display device includes a flexible display device using a flexible substrate as the substrate 110 .

[0032] The flexible substrate can be made of a polymer plastic film, preferably a film with high heat resistance to withstand the temperature during the manufacture of the display device. The flexible substr...

Abstract

A sealant pattern for sealing a sealing member for sealing a light-emitting diode formed on a substrate, and a flat display device having the sealant pattern includes: a substrate having an image display unit in A display device is disposed on the image display unit; and a sealing member for sealing the substrate with a sealant. The sealant includes a main pattern formed to surround the image display unit and a protruding portion protruding from the main pattern at a corner of the substrate. The main pattern of the sealant includes a frame pattern surrounding the image display unit along the edge of the substrate. The protruding portion of the encapsulant includes at least one bar or block pattern protruding from the main pattern at one corner of the substrate.

Description

[0001] This application claims all of the application No. 10-2004-0095942, filed with the Korean Intellectual Property Office on Nov. 22, 2004, entitled "Sealant Pattern for Flat Panel Display and Flat Panel Display Using the Same" rights and interests, this application cites and includes this application. technical field [0002] The present invention relates to a flat display panel, and more particularly, to a sealant having protrusions on corners of a substrate and an organic light emitting diode (OLED) using the sealant. Background technique [0003] Light emitting diodes are classified into inorganic light emitting diodes (LEDs) and organic light emitting diodes (OLEDs) according to the kind of light emitting compounds used to form an organic film layer between a positive electrode and a negative electrode. Inorganic LEDs have a long lifetime, but have low luminous efficiency and high driving voltage. On the other hand,...
