2/8/2026 · Displays · 8 min

TL;DR

• E-Ink excels in readability, battery life, and simplicity, making it ideal for avid readers and minimalists.
• E-Ink Color adds versatility with color for annotations, PDFs, and creative tasks, but at the cost of higher prices and slightly reduced battery performance.

What is E-Ink Technology?

E-Ink, also known as electronic paper display (EPD), is a display technology designed to mimic the appearance of traditional ink on paper. Unlike LCD or OLED screens, E-Ink relies on electronic ink particles that reflect ambient light, reducing eye strain and providing a more natural reading experience.

E-Ink Color is the next evolution, introducing color capabilities to traditional monochrome EPDs. By layering a color filter array (CFA) over the standard E-Ink display, these devices can show a range of colors without sacrificing the core benefits of E-Ink technology.
