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.
