IMAGING DEVICE AND ELECTRONIC APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18682978 titled 'IMAGING DEVICE AND ELECTRONIC APPARATUS

Simplified Explanation:

This patent application describes an imaging device that can reduce size in in-plane directions without sacrificing operation capability. The device includes a base body, a pixel array unit, a first inter-identical color pixel wall member, and an inter-pixel light shielding film.

  • The pixel array unit contains first color pixels and second color pixels on the base body.
  • The first color pixels have a first color filter and a first photoelectric conversion unit, while the second color pixels have a second color filter and a second photoelectric conversion unit.
  • A first inter-identical color pixel wall member with a lower refractive index than the first color filter is positioned among the first color filters.
  • An inter-pixel light shielding film is placed between the first color pixels and the second color pixels to block light transmission.

Key Features and Innovation:

  • Reduction in size in in-plane directions without compromising operation capability.
  • Pixel array unit with first and second color pixels for image capture.
  • First inter-identical color pixel wall member with lower refractive index for improved light transmission.
  • Inter-pixel light shielding film to prevent unwanted light transmission between pixels.

Potential Applications:

This technology can be used in various imaging devices such as cameras, smartphones, and medical imaging equipment.

Problems Solved:

The technology addresses the challenge of reducing the size of imaging devices without affecting their performance.

Benefits:

  • Compact design without sacrificing functionality.
  • Improved image quality due to enhanced light transmission control.
  • Enhanced portability and usability in various applications.

Commercial Applications:

Potential commercial applications include consumer electronics, medical imaging devices, surveillance systems, and industrial inspection equipment.

Prior Art:

Readers can explore prior art related to this technology by researching patents in the field of imaging devices, pixel array units, and light shielding films.

Frequently Updated Research:

Questions about Imaging Device Technology:

1. How does the lower refractive index of the first inter-identical color pixel wall member improve light transmission? 2. What are the specific advantages of using an inter-pixel light shielding film in imaging devices?


Original Abstract Submitted

An imaging device that makes it possible to achieve a reduction in size in in-plane directions without sacrificing its operation capability is provided. The imaging device includes: a base body; a pixel array unit; a first inter-identical color pixel wall member; and an inter-pixel light shielding film. The pixel array unit is one where a plurality of first color pixels and a plurality of second color pixels are disposed on the base body. The plurality of first color pixels lie adjacent to each other and each include a first color filter and a first photoelectric conversion unit that receives first color light passed through the first color filter and performs photoelectric conversion on the first color light. The plurality of second color pixels lie adjacent to each other and each include a second color filter and a second photoelectric conversion unit that receives second color light passed through the second color filter and performs photoelectric conversion on the second color light. The first inter-identical color pixel wall member is positioned in a gap among the plurality of first color filters, and has a refractive index lower than a refractive index of the first color filter. The inter-pixel light shielding film is positioned in a gap between the plurality of first color pixels and the plurality of second color pixels, and suppresses transmission of light entering the pixel array unit.
