4.2-inch for 4 E-Paper Module E-Ink Display B Description
No backlight required; the last screen display can remain visible for a long time after a power outage.
Very low power consumption; basically only draws power when updating.
The E-Ink screen uses "microcapsule electrophoresis display" technology for image display. The operating principle is that nanoparticles suspended in liquid migrate under the influence of an electric field and, through reflection in ambient light, create a display effect similar to that of conventional printed paper.
The E-Ink screen can clearly display images in ambient light such as bright light and without backlighting, and the viewing angle is almost 180. Due to its display effect comparable to conventional paper, it is frequently used in applications such as… used.
Application scenarios: Applicable to price tags in shopping malls, equipment labels, electronic shelf labels, conference name badges, etc.
