  • Publication number: 20250119566
    Abstract: A method of decoding a picture frame from a bitstream includes grouping N tiles of the picture frame into P sub-pictures, the P sub-pictures being non-overlapping with each other, a first sub-picture of the P sub-pictures comprising Q columns of tiles, N being an integer exceeding 1, P, Q being positive integers, and partitioning a first column of tiles of the Q columns of tiles into M sub-slices, the M sub-slices being non-overlapping with each other, M being an integer exceeding 1. The method further includes obtaining first tile information from a memory prior to decoding a current sub-slice of the M sub-slices, a first processor decoding the current sub-slice of the M sub-slices according to the first tile information, and storing second tile information in the memory upon completion of decoding the current sub-slice of the M sub-slices.

  • Publication number: 20150077687
    Abstract: A liquid crystal display device includes a first substrate, a second substrate opposite the first substrate, a fence structure, a plurality of cholesteric liquid crystals having mutually different color, and a medium layer. The fence structure is disposed between the first substrate and the second substrate to divide a space between the first substrate and the second substrate into different sub-pixel channels. The cholesteric liquid crystals are disposed into the sub-pixel channels to form different liquid crystal cells having mutually different colors. The medium layer is disposed in at least one of the sub-pixel channels to allow the liquid crystal cells to have mutually different cell gaps.
