Abstract: Optical sensors including a light-impeding pattern are provided. The optical sensors may include a plurality of photoelectric conversion regions, a plurality of lenses on the plurality of photoelectric conversion regions, and a light-impeding layer extending between the plurality of photoelectric conversion regions and the plurality of lenses. The light-impeding layer may include an opening between a first one of the plurality of photoelectric conversion regions and a first one of the plurality of lenses. The optical sensors may be configured to be assembled with a display panel such that the plurality of lenses are disposed between the light-impeding layer and the display panel.

Abstract: An image sensor includes a normal pixel, a first auto-focus (AF) pixel, and a second AF pixel, each of the normal pixel, the first AF pixel and the second AF pixel including a photodiode. The image sensor further includes a normal microlens disposed on the normal pixel, and a first AF microlens disposed on the first AF pixel and the second AF pixel. The photodiode of the normal pixel, the photodiode of the first AF pixel, and the photodiode of the second AF pixel are respectively disposed in photo-detecting areas of a semiconductor substrate. A height of the first AF microlens in a vertical direction from a top surface of the semiconductor substrate is greater than a height of the normal microlens in the vertical direction from the top surface of the semiconductor substrate.

Abstract: An image sensor includes: a chip structure including normal pixels and auto focus pixels; a grid structure disposed on the chip structure; and color filter regions defined by the grid structure over the chip structure. The color filter regions include normal filter regions and auto focus filter regions. The normal filter regions correspond to the normal pixels. The chip structure includes a first region at a first distance, and a second region a second distance greater than the first distance. The auto focus filter regions include a first auto focus filter region on the first region and a second auto focus filter region on the second region. A first width of a first grid portion disposed adjacent the first auto focus filter region among the grid structure is narrower than a second width of a second grid portion disposed adjacent the second auto focus filter region among the grid structure.

Abstract: An image sensor includes a pixel array in which a plurality of normal pixels and a plurality of autofocus (AF) pixels are disposed, and a logic circuit. The logic circuit provides an autofocus function using a phase difference between pixel signals obtained from each of the plurality of AF pixels. Each of the AF pixels includes a single AF lens disposed on a pair of pixel areas. An AF lens of the AF pixel spaced apart from a center of the pixel array may have an area larger than an area of the AF lens of the AF pixel adjacent to the center.
