E-ink display is a type of digital display technology that makes a screen look-like paper with ink. It uses electronic ink to create a black-and-white image.

When a voltage is applied, the particles move to the top or bottom layer. This movement creates an image.

When the particles are at the top, it appears white because the particles reflect the light to the viewer.

When the particles are at the bottom, it appears black because the colored dye absorbs the light.

It can form a desired image by controlling the voltage applied to each pixel.

E-ink displays offer several advantages over traditional LCD and OLED displays. They include the following:

1. Use Lower Power
2. Easy to read
3. No Harm to the eyes
4. Wide viewing angle
5. A Long Lifetime
