  • Publication number: 20240137511
    Abstract: Disclosed herein are a video decoding method and apparatus and a video encoding method and apparatus. In video encoding and decoding, multiple partition blocks are generated by splitting a target block. A prediction mode is derived for at least a part of the multiple partition blocks, among the multiple partition blocks, and prediction is performed on the multiple partition blocks based on the derived prediction mode. When prediction is performed on the partition blocks, information related to the target block may be used, and information related to an additional partition block, which is predicted prior to the partition block, may be used.

  • Patent number: 7968882
    Abstract: A flexible display device adapted to prevent a disconnection of pad electrode and a line short-circuit is disclosed. The flexible display device and the manufacturing method thereof according to the present embodiments forms only the barrier film or no layer on the mother substrate in the vicinity of the cut line which divides the mother substrate into the TFT substrate. Even when the mother substrate is pressed using a press machine, cracks or lifts of layers are not generated in the TFT substrate unlike the conventional technology so that a disconnection is not generated in the gate pad electrode or the data pad electrode. Thus, line short-circuits generated as the layers are separated and attached to the TFT substrate can be prevented.
