Abstract: Provided is an image decoding method including determining a plurality of coding units in a chroma image by hierarchically splitting the chroma image, based on a split shape mode of blocks in the chroma image of a current image, and decoding the current image, based on the plurality of coding units in the chroma image. In this regard, the determining of the plurality of coding units in the chroma image may include, when a size or an area of a chroma block from among a plurality of chroma blocks to be generated by splitting a current chroma block in the chroma image is equal to or smaller than a preset size or a preset area, not allowing splitting of the current chroma block based on a split shape mode of the current chroma block, and determining at least one coding unit included in the current chroma block.

Abstract: Disclosed are a display device and a display panel including a substrate, a first subpixel array including first subpixels arranged in a first region on the substrate, a second subpixel array including second subpixels arranged in a second region on the substrate, and a third subpixel array including third subpixels arranged in a third region on the substrate. The first region, the second region, and the third region are spatially separated and provided side by side on a same surface of the substrate. The first subpixels are grouped by a first primary color and are patterned as the first subpixel array in the first region. The second subpixels are grouped by a second primary color and are patterned as the second subpixel array in the second region. The third subpixels are grouped by a third primary color and patterned as the third subpixel array in the third region.
