Waveshare 4.2" 400x300 ePaper display module BW

Product detailed description

E-Ink (or E-Paper) is a so-called electrophoretic display, i.e. a display containing white particles in microcapsules dispersed in a thin layer of dark viscous solution. By applying a short impulse, these white particles will move, possibly tilting towards the front side of the display, which causes the given pixel to appear white. By applying an impulse of opposite polarity, the given pixel appears black. High viscosity of the solution causes micro-particles to remain in their position without change practically permanently.

Unlike conventional displays, ePaper does not glow but reflects light, just like ordinary paper. It's an ideal display for battery-powered devices because it only needs electricity to change the displayed content.
