ADVANTAGE OF E-INK SCREEN

The electronic ink screen uses a technique called "microcapsule electrophoresis display" to display images. It works because charged nanoparticles suspended in a liquid are transported by an electric field and reflected under ambient light to produce a display effect similar to that of traditional printed paper. E-Ink screens can display images clearly in ambient light, natural light and so on, without backlighting, and can be seen from an angle of almost 180°. Because of its comparable display effect to traditional paper, it is often used in applications such as readers.

 

APPLICATION
 

The electronic paper display supports user's custom setting to display text, pictures, QR code and other information. Compared with the traditional LCD electronic price tag which is less than 120°, the visual angle of electronic paper is more than 170°. Moreover, compete with LCD products, the electronic paper display has a higher screen contrast, which brings higher use experience to customers in practical application.

 

Due to the screen engineering characteristics, the electronic paper price tag only generates power consumption when refreshing the screen content, and daily display does not consume energy. Longer service life adapts to all kinds of long-time standby mode working environment, supports 7*24H*365 days of uninterrupted work. As one of the major technologies of the IOT, e-paper is bound to receive more attention in the future. You're going to see more and more products based on electronic paper screens in the near future.

 

ABOUT TFT LCD DISPLAY

E Ink displays are referred to as "reflective displays."In an LCD, or "emissive display", light from a backlight is projected through the display towards your eyes. In an E Ink display, no backlight is used; rather, ambient light from the environment is reflected from the surface of the display back to your eyes. As with any reflective surface, the more ambient light, the brighter the display looks. This attribute mimics traditional ink and paper, and users of E Ink displays have said that they do not have the same eye fatigue as with LCDs when reading for long periods of time.
Therefore, eliminating the need for a backlight significantly increases the battery life versus using a traditional LCD.
