Comparison of Display Effect Between LCD and ePaper Screens

Compared with traditional digital screens, the ePaper display is a healthier option. LCDs often radiate bright light, specifically blue light, which has negative effects on the eyes and health. According to reports, brighter, bluer (or cooler) light from LCDs causes higher levels of stress on retinal cells, and ePaper is up to three times healthier for the eyes.
