  • Patent number: 8796920
    Abstract: Disclosed is an organic light emitting display which avoids an occurrence of Newton's rings in coalesced substrate and sealing substrate. A first substrate includes a pixel region and a non-pixel region. An array of organic light emitting pixels including a first electrode, an organic layer, and a second electrode is formed at the pixel region. A second substrate opposes the first substrate. A frit is disposed between the non-pixel region of the first substrate and the second substrate for interconnecting the first substrate and the second substrate. The second electrode of the array directly contacts a region corresponding to a pixel region of the second substrate.

  • Patent number: 8688739
    Abstract: A system and method for data matching are disclosed. A user terminal included in the system includes a data provider, a data consumer, and a mapper. The data provider receives life log data of a user which is collected by at least one life log collecting apparatus. The data consumer receives the life log data from the data provider, and compares the life log data and reference data received from a service server to determine whether a difference between the life log data and the reference data exceeds a predetermined threshold value. The mapper maps the service server which provides the reference data corresponding to information of the life log data received from the data provider. Accordingly, the usability to of life log apparatuses can increase.

  • Patent number: 8253686
    Abstract: Provided are a pointing apparatus capable of providing haptic feedback, and a haptic interaction system and method using the same. The pointing apparatus includes a wireless communication unit, a controller, and a haptic stimulator. The wireless communication unit receives an event including haptic output information through wireless communication with the outside. The controller generates a control signal for reproducing a haptic pattern corresponding to the haptic output information. The haptic stimulator reproduces the haptic pattern by means of the control signal. Thus, it is possible to increase the performance and usability of a user interface of a user terminal including a touch screen.
