The Advantages of E Ink Displays


		E Ink displays use electrophoretic imaging technology, reflecting ambient light to create a paper-like appearance without the need for a backlight, providing a glare-free, energy-efficient reading experience. Since the display doesn't require constant power to maintain the image, it is highly energy-efficient. E Ink screens offer nearly 170° viewing angles and high contrast, making them ideal for smart devices applications focused on eco-friendly, eye-friendly readability.
