IMAGE SENSING DEVICE AND METHOD FOR MANUFACTURING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18365423 titled 'IMAGE SENSING DEVICE AND METHOD FOR MANUFACTURING THE SAME
The patent application describes an image sensing device with multiple color filters and a grid structure to block light between them.
- The device has first, second, third, and fourth color filters for different colors.
- A grid structure is placed between the color filters to prevent light leakage.
- Some color filters are shorter than the grid structure, while others are taller.
- This design helps in better light filtering and color accuracy.
Potential Applications: This technology can be used in digital cameras, smartphones, and other imaging devices for improved color reproduction and image quality.
Problems Solved: The device addresses issues related to color cross-talk and light leakage between different color filters, resulting in more accurate color reproduction.
Benefits: Enhanced color accuracy, improved image quality, and better overall performance of imaging devices using this technology.
Commercial Applications: This technology can be beneficial for companies manufacturing digital cameras, smartphones, and other devices with image sensors, enhancing their product quality and competitiveness in the market.
Prior Art: There may be existing patents or technologies related to color filter arrays in image sensors, but this specific combination of color filters and grid structure may be unique.
Frequently Updated Research: Stay updated on advancements in image sensor technology, color filter arrays, and light-blocking structures to enhance the performance of image sensing devices.
Questions about the Technology:
- Question 1: How does the grid structure prevent light leakage between different color filters?
- Question 2: What are the potential commercial implications of this technology in the imaging industry?
Original Abstract Submitted
An image sensing device includes a plurality of first color filters configured to transmit light corresponding to a first color, a plurality of second color filters configured to transmit light corresponding to a second color, a plurality of third color filters configured to transmit light corresponding to a third color, a plurality of fourth color filters configured to transmit light corresponding to a fourth color, and a grid structure disposed between the first to fourth color filters and structured to block light from one color filter to another color filter. Some color filters from among the first to fourth color filters are formed to have a lower height than the grid structure, and the remaining color filters are formed to have a higher height than the grid structure.
