  • Publication number: 20230154955
    Abstract: An image sensing device includes a plurality of color filter blocks, each of which includes a plurality of color filters arranged adjacent to each other in a first direction and a second direction perpendicular to the first direction and having the same color, first grid structures including a first air layer and disposed between the color filter blocks adjacent to each other in the first direction; second grid structures including a second air layer and disposed between the color filter blocks adjacent to each other in the second direction, and a third grid structure including a third air layer and disposed between the color filters within each of the color filter blocks. The first to third air layers are structurally separate from each other.

  • Publication number: 20210366969
    Abstract: An image sensing device may include an image sensing pixel array including a plurality of image sensing pixels operable to respond to light and to produce imaging pixel signals, and a first grid structure disposed between image sensing pixels to separate adjacent image sensing pixels. The image sensing pixel array is structured to include a center area located at or near a center of the image sensing pixel array, first and second diagonal edge areas disposed on opposite sides of the center area in a first diagonal direction, and third and fourth diagonal edge areas disposed on opposite sides of the center area in a second diagonal direction that is different from the first diagonal direction. The first grid structure includes a bent portion in at least one of the first to fourth diagonal edge areas to cover one vertex and adjacent parts of each image sensing pixel.
