What is E-ink?
Electronic Ink
It is a display technology that offers a paper-like appearance and consumes energy only when the page changes.
Overview
E-ink is based on the principle of black and white particles inside tiny capsules on the screen moving via an electric field. Unlike traditional screens, it does not emit constant light, so it is readable like paper even in daylight and does not strain the eyes. Its biggest advantage is that it consumes no energy while the image is static.
How it works
Inside each pixel on the screen, there are charged particles. When an electric current is applied, these particles rise to the surface to create black or white colors. Once the image is formed, it remains there even if you cut off the screen's power.
Where it is used
It is frequently used in e-book readers, digital price tags, and some low-energy smartwatch screens.
Commonly confused with
It is confused with LCD or OLED screens; they constantly emit light and consume energy, whereas e-ink only consumes energy at the moment of change.
Frequently asked questions
Why are E-ink screens not in color?
Its technology is fundamentally based on black and white particles; although color e-ink screens exist, they are more complex and costly.
Why is the response time of an E-ink screen slow?
Because the particles need to physically displace, it is not suitable for rapid changes such as playing video.
