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. Accordingly, the contact defect between the connection electrode and the contact spacer can be prevented and the structural strength of the OLED device can be greatly improved.

Organic electro-luminescence display device and manufacturing method thereof

The method for bonding a glass cap according to the present invention comprises the steps of, forming a plurality of recesses on a side of a glass corresponding to a substrate; forming a plurality of light non-transmittable layers on a surface of the glass opposite to a surface corresponding to the substrate; dispensing a sealant on a substrate-bonding region of the glass or on a cap-bonding region of the substrate; bonding the glass to the substrate in the state that each active area formed on the substrate is received in each recess of the glass; curing the sealant dispensed on the sealing-dispensing region by irradiating ultraviolet rays to a side of the glass to which the substrate is not bonded; and dicing the bonded glass and substrate to make the individual devices. The present invention intercepts the ultraviolet rays irradiated to the active areas of the substrate to protect the active areas, and so can cure completely the sealant dispensed on the metal lines.

Method for bonding a glass cap and mask for curing sealant

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.

Glass encapsulation cap, organic electroluminescent device having the same, mother glass substrate for producing multiple glass encapsulation caps, and manufacturing method thereof

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.
