Pervasive Displays E2741FS081 7.4" 800x480 ePaper red display

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.

This is a 7.4-inch electronic paper display with a resolution of 800x480, an SPI interface, and the ability to display black and white red images, logos, and icons. The image you display will last indefinitely without power - display the image and then turn off the power. Once these electronic paper display modules are updated, they do not require any power and can actually be completely disconnected, with the content remaining on the display for an unlimited time. This ePaper display is ideal for devices with low energy consumption powered by solar sources or batteries.

If the display does not refresh every 24 hours, it may lead to a phenomenon known as "Ghosting" or "Image Sticking". In case of use, it is recommended to refresh the display every 24 hours.
