  • Publication number: 20160268352
    Abstract: An organic light emitting diode display includes a stretchable substrate, a plurality of pixel forming plates, first and second pixels, and a cut-out groove. The pixel forming plates are on the substrate and spaced apart from each other. The first and second pixels are on respective first and second pixel forming plates of the plurality of the pixel forming plates adjacent in a first direction. The first and second pixel forming plates are connected by a first bridge. The cut-out groove are in the first and second pixel forming plates and adjacent to an area connected to the first bridge.

  • Patent number: 9367739
    Abstract: A proximity of a second user is sensed while a first user who is a registered user views an iris recognition portable device. Whether the second user is registered is checked according to whether an iris of the second user is recognized. The displayed screen may be altered when the second user is determined to be a non-registered user.

  • Publication number: 20140312321
    Abstract: An organic light emitting display device includes a first substrate having a plurality of organic light emitting structures thereon, a second substrate facing the first substrate to encapsulate the organic light emitting structures, an aperture under a lower surface of the first substrate, and an aperture controller under the lower surface of the first substrate. The organic light emitting structures define a pixel area. The second substrate has a light absorption area. The aperture corresponds to the light absorption area. The aperture controller is adjacent to the aperture.
