  • Publication number: 20090142489
    Abstract: Linear deposition sources are disclosed. In one embodiment, the linear deposition source includes a container accommodating evaporation material and a heater configured to generate heat energy such that vaporized material is discharged uniformly onto a substrate on which a deposition layer is formed. The heater is provided on the container, wherein a portion of the heater positioned at a center portion of the container in the longitudinal direction generates more heat energy than the other portion of the heater. The heater includes a coil configured in a sinusoidal pattern, wherein the curvature pitch or height of the portion of the coil positioned at the center portion of the container in the longitudinal direction is set to be different from that of the other portion of the coil. Further, the resistance of the portion of the coil positioned at the center portion of the container in the longitudinal direction may be set to be greater than that of the other portion of the coil.

  • Publication number: 20090066214
    Abstract: Disclosed are light emitting display and method of manufacturing the same. The light emitting display according to the present embodiments includes a first substrate including a plurality of light emitting devices and a pad portion, all of which are formed therein; a second substrate disposed to face the light emitting devices; and a bonding layer bonded to the light emitting devices and the second substrate, wherein a stepped portion is formed at a predetermined depth in an edge of the second substrate that is adjacent to the pad portion, and the bonding layer is extended to the stepped portion. Since the bonding layer is not bonded to the pad portion due to the depth of the stepped portion when the second substrate is bonded to the first substrate, poor electrical contact may be prevented, and it easy to remove the encapsulation substrate to expose the pad portion.

  • Publication number: 20090058294
    Abstract: Disclosed are a light emitting display device and a method for fabricating the same. The light emitting display device according to the present embodiments includes a first substrate including a pixel region and a non-pixel region surrounding the pixel region; a plurality of light emitting diodes disposed in the pixel region of the first substrate, and each including a first electrode, a light emitting layer, and a second electrode; and a second substrate disposed to face the first substrate. Also, the light emitting display device according to the present embodiments includes a sealant by coupling the first substrate to the second substrate to encapsulate the pixel region; and a spacer disposed between the first substrate and the second substrate and provided in a non-light emission region arranged between the adjacent light emitting diodes. In this case, the spacer is disposed on the second electrode of the non-light emission region to be in contact with the second substrate.

  • Publication number: 20090039760
    Abstract: Disclosed is a light emitting display device including a seal and a method of fabricating the same. The light emitting display device includes a first substrate composed of a pixel region and a non-pixel region disposed around the pixel region; a pad portion formed in the non-pixel region to supply a signal to the pixel region; a second substrate disposed to face the first substrate; and a seal provided between the first substrate and the second substrate and disposed to surround the pixel region. Here, the seal is disposed on a first side between the pixel region and the pad portion, on a second side facing the first side, and on an outer ring of third sides contacting both ends of the first side and the second side, and the seal disposed in the outer ring of the third sides is filled up to contour lines of the first substrate and the second substrate.
