Ereaders primarily use two display technologies: E Ink and LCD. E Ink displays use electronic ink particles to create text and images, closely resembling the look of ink on paper. They provide a paper-like reading experience, are easy on the eyes, and perform exceptionally well under direct sunlight. On the other hand, LCD displays use a backlight to illuminate the screen, resulting in vibrant colors and the ability to display multimedia content. However, prolonged reading on LCD screens may cause eye strain.
