Abstract: The present invention relates to an encapsulation cap, an organic electroluminescent device having the same, and a manufacture method thereof. The encapsulation cap protects each of elements in a device formed on a substrate from outside, comprising a sealing surface adhering to the substrate , wherein at least one groove is formed at an edge of the sealing surface. The encapsulation cap protecting each of elements in a device formed on a substrate from outside comprises a sealant surface adhering to the substrate and a holding part holding each of elements of the device, wherein a concave part is formed on the sealant surface along an edge that the sealing surface and the holding part meet. The encapsulation cap, the organic electroluminescent device having the same, and the manufacturing method thereof according to the present invention can prevent overflowing of a sealant because of the structure capable of holding extra-sealant applied to the sealing surface.

Abstract: An OLED device is disclosed. The OLED device includes a first substrate including a driver element and a connection electrode connected to the driver element, a second substrate including an organic light emission diode element, a contact spacer electrically connected to the connection electrode, and a sealant disposed into a cavity which is formed by the first and second substrates, the connection electrode, the organic light emission diode element, and the contact space. Herein, the sealant is bonded to the contact spacer and the connection electrode and maintains the electric connection between the contact spacer and the connection electrode. In this manner, the driver element and the organic light emission diode element are protected from external oxygen and/or moisture, and the electric connection between the connection electrode and the contact spacer is reinforced.

Abstract: An organic electro-luminescence device including a substrate, a first electrode, a light-emitting layer and a second electrode which are sequentially formed on the substrate, a packaging plate facing the substrate, and barcodes formed on the substrate and the packaging plate.

Abstract: Disclosed is an organic light emitting display device. The exemplary organic light emitting display device according to an exemplary embodiment of the present invention comprises a substrate, a displaying area located on the substrate, the displaying area comprising a plurality of sub pixels, each of which has an emission area; and a dummy area located on an area of the substrate other than the displaying area, the dummy area comprising a plurality of dummy patterns, wherein the dummy pattern contains the same material as that of the emission area.

Abstract: The invention relates to a barcode marking method and apparatus for an electro-luminescence display device. According to the barcode marking method and apparatus for an electro-luminescence display device of the present invention includes, an information barcode is marked on the electro-luminescence display devices by using the ink jetted from the ink-jet head while moving at least any one of the stage and the ink-jet head.
