  • Publication number: 20240074235
    Abstract: A display apparatus is provided. The display apparatus may include a light-emitting device and a pixel driving circuit electrically connected to the light-emitting device. The pixel driving circuit may supply a driving current corresponding to a data signal to the light-emitting device according to a gate signal. For example, the pixel driving circuit may include at least one thin film transistor. The thin film transistor may include an active pattern comprising an oxide semiconductor. A source region of the active pattern overlaps a source semiconductor pattern, and a drain region of the active pattern overlaps a drain semiconductor pattern. The source semiconductor pattern and the drain semiconductor pattern may include n-type impurities. A channel region of the active pattern may be outside the source semiconductor pattern and the drain semiconductor pattern. Thus, in the display apparatus, reliability of the pixel driving circuit may be improved.

  • Publication number: 20240073445
    Abstract: Disclosed is a method of decoding an image and a method of encoding an image. The method of decoding an image includes: obtaining motion-constrained tile set information; determining, on the basis of the motion-constrained tile set information, a first boundary region of a collocated tile set within a reference picture, which corresponds to a motion-constrained tile set; padding a second boundary region corresponding to the first boundary region; and performing inter prediction on the motion-constrained tile set by using a collocated tile set that includes the padded second boundary region.

  • Patent number: 6910872
    Abstract: A variable rotary compressor with a capacity being variable as desired includes a drive device generating a rotating force, a rotating shaft connected to the drive device at a first end thereof and rotated by the drive device, and a cylinder through which a second end of the rotating shaft passes. Two or more compressing chambers are provided in the cylinder such that the two or more compressing chambers are sequentially arranged along an axial direction of the rotating shaft. Rollers are eccentrically installed on the rotating shaft such that the rollers are arranged, respectively, in the two or more compressing chambers. A one-way clutch is installed on the rotating shaft to selectively transmit the rotating force to at least one of the rollers in accordance with a rotating direction of the rotating shaft. During operation of the rotary compressor, only one of the rollers is selectively rotated.

  • Patent number: 6860724
    Abstract: A rotary compressor having a plurality of compression chambers and adapted to vary a compression capacity according to a direction of rotation of roller pistons within the compression chambers. A rotating shaft provided with a plurality of eccentric parts drives the roller pistons to compress refrigerant in the compression chambers by eccentric rotations of the eccentric parts. A reversible motor selectively rotates the rotating shaft in opposite directions, and a clutch engages the roller pistons such that the roller pistons perform a compressing action or an idle action according to a rotating direction of the rotating shaft, thus varying the compression capacity of the compressor according to a rotating direction of the rotating shaft. Thus, the compression capacity may be varied without using an inverter circuit.

  • Patent number: 5828647
    Abstract: A disk changer for shortening the time required for the extraction of a disk from a magazine portion and the performance of the recording/reproducing operation is provided. First and second extracting members for extracting a disk from the magazine portion, and first and second deck members including recording and reproducing elements thereon, are simultaneously moved to the vicinity of a selected disk. Then, the disk is extracted from the magazine portion, and the recording/reproducing operation is carried out. The recording/reproducing operation can also be performed with respect to a disk from outside the disk changer via a tray member.
