  • Publication number: 20250040343
    Abstract: A display device includes a display panel including an antireflection layer on a light emitting element layer which includes a first pixel defining layer in which an opening defining a light emitting area of a first pixel is defined, and a second pixel defining layer in which an opening defining a light emitting area of a second pixel is defined. The antireflection layer includes first and second light blocking layers respectively overlapping the first and second pixel defining layers, and includes a first gap defined by a length of a predetermined direction from an edge of the opening to an edge of an opening of the first light blocking layer, and a second gap defined by a length from an edge of the opening to an edge of an opening of the second light blocking layer in the predetermined direction. The first gap is less than the second gap.

  • Patent number: 12206894
    Abstract: Disclosed herein are a method, an apparatus, and a storage medium for image encoding/decoding. An intra-prediction mode for the target block is derived, and intra-prediction for the target block that uses the derived intra-prediction mode is performed. The intra-prediction mode for the target block is derived using an artificial neural network, and an MPM list for the target block is derived using information about the target block, pieces of information about blocks adjacent to the target block, and the artificial neural network. The artificial neural network outputs one or more available intra-prediction modes. Further, the artificial neural network outputs match probabilities for one or more candidate intra-prediction modes, and each of the match probabilities for the candidate intra-prediction modes indicates a probability that the corresponding candidate intra-prediction mode matches the intra-prediction mode for the target block.

  • Patent number: 11301127
    Abstract: Methods and apparatus are provided for correcting an input error in an input apparatus capable of touch inputs of a first touch input scheme and a second touch input scheme. Upon detecting a touch input of the first touch input scheme, an activity corresponding to the detected touch input is executed and activity execution information corresponding to the activity is stored. The activity executed in accordance with the touch input of the first touch input scheme is cancelled, when a touch input of the second touch input scheme occurs before the touch input of the first touch input scheme is released or before a preset timer expires. The first touch input scheme and the second touch input scheme are different schemes.
