Abstract: A method of video decoding includes determining whether a maximum number of merge candidates is signaled in a coded video bitstream for a current block of a current picture. The method further includes, in response to a determination that the maximum number of merge candidates is signaled for the current block, setting a maximum number of intra block copy (IBC) candidates for the current block to a value of the signaled maximum number of merge candidates, and, in response to a determination that the maximum number of merge candidates is not signaled for the current block, setting the maximum number of IBC candidates to a predetermined value. The method further includes constructing a candidate list of vector predictors based on at least one of the maximum number of merge candidates or the maximum number of IBC candidates for the current block.

Abstract: Aspects of the disclosure provide method and apparatus for video coding. In some examples, an apparatus includes processing circuitry for video decoding. The processing circuitry decodes prediction information of a current block from a coded video bitstream. The prediction information is indicative of an intra block copy mode. The processing circuitry selects, from a set of multiple candidate resolutions, a resolution of a block vector difference for the current block, and determines a block vector of the current block according to the selected resolution of the block vector difference and a block vector predictor of the current block. Then, the processing circuitry reconstructs at least one sample of the current block according to the block vector.

Abstract: A color-filter-on-array (COA) type liquid crystal panel and a manufacturing method thereof are disclosed. An alignment film in the COA type liquid crystal panel is formed by a photo-alignment technology of an ultraviolet induced multi-domain vertical alignment (UV2A). Also, a problem of image sticking of an existing COA type liquid crystal display is improved by controlling the dielectric constant (??) of the liquid crystal molecules of a liquid crystal layer in the COA type liquid crystal panel.
