How Samsung’s semiconductor science popularization allows mobile phones to have 108 million pixels, breaking the limit

In recent years, 100-megapixel mobile phones have been loved by many people, and Samsung has actually contributed to it. Recently, Samsung released an image sensor called “ISOCELL HM3”. It has 108MP pixels and is equipped with high-sensitivity shooting technology. So how does it make the phone have 108 million pixels?

To develop an image sensor with 108 million pixels, some limitations must be broken. First, the pixel size must be greatly reduced, so that 108 million pixels can be integrated into an image sensor chip that is only the size of a small nail; and as the pixels become smaller, the pixels There will be a problem that it is difficult to receive light, and there will also be pixel interference. To this end, Samsung has developed a pixel isolation technology called “isocell”, which reduces interference between pixels by installing an insulating layer on each pixel.

   solves the problem of pixel interference, but also needs to solve the problem of noise in low light environment or night shooting. To this end, Samsung has developed a pixel synthesis technology called “Nonacell”, which receives more light by synthesizing 9 adjacent pixels into one large pixel. The light information of 9 pixels is merged into one, and the amount of light input will be significantly increased. Even in a dark light environment, pure and clear photos and videos can be taken.>>>>>>>>>>>>>>>>>>>>Mobile phone battery
