  • Patent number: 10804330
    Abstract: A multi-view display device displays a first image, a second image, and a third image generated using the arrangement structure of subpixels and color filters, the gaps between the subpixels, and the arrangement structure of black matrices. The first to third red subpixels of the first to third subpixel groups display a red portion of the first to third images, the first to third green subpixels of the first to third subpixel groups display a green portion of the first to third images, and the first to third blue subpixels of the first to third subpixel groups display a blue portion of the first to third images.

  • Patent number: 8102827
    Abstract: Provided are a peer MR authentication method, a multiple peer CoAs registration method, a failover method for multi-homed mobile networks, and a computer readable recording medium thereof. The registering method includes the steps of: a) determining whether a second MR is around a first MR; b) at the first MR, transmitting a peer request message to the second MR; c) at the first MR, requesting a HA of the first MR to authenticate the second MR; d) at the HA, transmitting a peer registering request message to the second MR with a prefix of the first MR that transmit the authentication request message to perform RR authentication; and e) at the HA, notifying the authentication result of the second MR to the first MR when receiving a RR authentication result message including the prefix of the first MR to be registered as a peer from the second MR.
