Ugreen's Magic E-Ink Case brings color e-ink back display

Ugreen has unveiled the Magic E-ink Screen Case for iPhone Pro models, a protective shell with a 3.7-inch color electronic-ink back panel that can display a user-selected image without consuming continuous power.

Display panel and image transfer

The case uses a 3.7-inch color e-ink panel Ugreen says supports six particle colors and retains readability under strong, direct light. Users select or design an image in a companion app and transfer it to the case via NFC. Ugreen states the initial data transfer takes about 20 seconds and the panel refresh requires about 20 seconds, so replacing an image takes roughly 40 seconds in total.

According to Ugreen, NFC-based transfers consume negligible energy and, once an image is fixed, the e-ink panel requires no power to preserve that image, so the display remains even if the phone is switched off. A long press of the right-side button disables the case's NFC antenna, which Ugreen says prevents interference with the phone's electronic payment functions.

Materials, controls and protection

Ugreen describes the case construction as a combination of thermoplastic polyurethane, polycarbonate and microfiber. It is offered in matte black, mist white and burgundy finishes. Metal buttons are provided for camera operation, and a separate NFC button is located on the case edge.

Protective features include air-cushion corners and raised edges designed to reduce scratches. The case edge stands about 1 millimeter above the phone's display and about 0.7 millimeters above the camera lenses.

Price, availability and context

Ugreen priced the Magic E-ink Screen Case at 279 yuan (about 40 dollars). The company says the product is on sale in China and is not yet available outside that market.

Second-screen accessories for iPhones are becoming more common. Earlier examples include DockCase's Selfix case, which adds a second display for selfies on the iPhone 17 Pro, and small e-reader accessories from Xteink that attach via MagSafe. Ugreen's approach focuses on a simple, persistent image display rather than camera previews or reading functions.
