Frequently Asked Questions (FAQs)

Q1. What is the difference between e-paper and LCD?
A1. E-paper uses reflective technology, mimicking the appearance of paper, while LCD displays emit light. E-paper offers higher contrast and power efficiency, but LCDs have faster refresh rates and can display a wider range of colors.

Q2. Can e-paper displays be used in direct sunlight?
A2. Yes, e-paper displays are designed to be readable in direct sunlight due to their reflective nature.

Q3. Are e-paper displays harmful to the eyes?
A3. No, e-paper displays emit very low levels of blue light, which is known to contribute to eye strain. E-paper is generally considered safe and comfortable for extended reading sessions.

Tablet Computer with Electronic Paper Screen

Tablet computers with electronic paper (e-ink) screens offer advantages over traditional tablets with LCD or OLED screens. These e-ink screens provide a more paper-like reading experience with high contrast and low power consumption, making them ideal for extended reading sessions without eye strain. Additionally, they are less reflective and better suited for use in bright outdoor environments. While e-ink screens refresh slower than traditional screens, their low power consumption allows for longer battery life. Tablet computers with e-ink screens are often used for reading electronic books, textbooks, and other text-heavy content.
