  • Patent number: 11949881
    Abstract: The present invention discloses an encoding apparatus using a Discrete Cosine Transform (DCT) scanning, which includes a mode selection means for selecting an optimal mode for intra prediction; an intra prediction means for performing intra prediction onto video inputted based on the mode selected in the mode selection means; a DCT and quantization means for performing DCT and quantization onto residual coefficients of a block outputted from the intra prediction means; and an entropy encoding means for performing entropy encoding onto DCT coefficients acquired from the DCT and quantization by using a scanning mode decided based on pixel similarity of the residual coefficients.

  • Publication number: 20100214309
    Abstract: A method of generating a common voltage for driving a display panel includes; comparing image data of a previous frame with image data of a present frame to determine whether the image data of the previous frame, which is received during a first setting time, is substantially the same as the image data of the present frame, determining a voltage level of the common voltage applied to the display panel in accordance with whether the image data of the previous frame is substantially the same as the image data of the present frame, generating the common voltage corresponding to the determined voltage level, and providing the display panel with the common voltage.

  • Publication number: 20080174932
    Abstract: A capacitor assembly includes a first electrode, a second electrode, a dielectric portion, a body and a conductive cover. The second electrode overlaps the first electrode. The dielectric portion is interposed between the first and second electrodes. The body surrounds an outer surface of the dielectric portion, the first electrode and the second electrode, and partially exposes end portions of the first and second electrodes. The conductive cover covers a side surface of the body, and has a greater width than a width of each of the end portions of the first and second electrodes. Therefore, yield of the capacitor assembly is increased, and defects are decreased.
