GoKawiilHow E-Ink Technology Enables Ereaders' Paper-Like Displays and Long Battery Life
E-ink technology uses electromagnetic principles to create paper-like screens that can display static images without drawing power, giving ereaders battery life that can span weeks or months compared to days for tablets like the iPad. The underlying mechanism is rooted in basic physics, though the precise chemistry and electronics involved are complex and limit how competitive e-ink devices can be against mainstream tablets.
