What is an "e ink e paper" display?
An e-paper display, also known as an electronic paper (e paper display) uses electrophoretic microcapsule technology to present data. This means that it mimics the appearance of standard ink found on traditional paper. This type of technology is extremely user-friendly - the screens emit no blue glow, are passively reflective and provide a wide viewing angle. All these features make our eyesight less fatigued during use, and reading gives us even more pleasure than before.
Differences in displaying content on various types of screens.
Image displayed in two colors: black and white.
