IMAGE SENSORS INCLUDING META-STRUCTURE FOR COLOR SEPARATION AND ELECTRONIC DEVICES INCLUDING IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18142219 titled 'IMAGE SENSORS INCLUDING META-STRUCTURE FOR COLOR SEPARATION AND ELECTRONIC DEVICES INCLUDING IMAGE SENSOR
Simplified Explanation
- The patent application describes meta-optical elements and image sensors that utilize a meta-pattern. - The image sensor consists of multiple pixels, each containing a photoelectric conversion layer with at least one photoelectric conversion element. - A color routing meta-structure layer is positioned opposite the photoelectric conversion layer in each pixel. - The color routing meta-structure layer has a symmetrical structure with respect to the center of the pixel. - The meta-structure within the color routing meta-structure layer has a multi-layer structure with a varying refractive index perpendicular to the surface where light is incident. - The purpose of this innovation is to improve the performance and efficiency of image sensors by optimizing the routing of different colors of light within each pixel.
Original Abstract Submitted
The present disclosure provides meta-optical elements and image sensors using a meta-pattern and apparatuses including the image sensors. In an embodiment, an image sensor includes a plurality of pixels. Each pixel of the plurality of pixels includes a photoelectric conversion layer including at least one photoelectric conversion element, and a color routing meta-structure layer provided at a position facing the photoelectric conversion layer. The color routing meta-structure layer includes a meta-structure having a symmetrical structure with respect to a center of a corresponding pixel, and a multi-layer structure having a refractive index that varies in a direction perpendicular to a light-incident surface.
