Working Principle Using NFC and electronic ink screen technology, use the APP which provided by QR code in the package to edit and transmit to the back screen of the mobile phone case.

Technology UpgradeThe previous smart ink NFC mobile phone case screen only has 3 colors of pigments, black, white, and red. The pigments of our 4-color ink screen are black, white, red, and yellow, which has significantly improved the clarity and fineness of the photo display

Good PointsThe reason why choose the ink screen as the display is because its display does not require continuous power supply, does not generate heat, radiation-free,and can be displayed for a long time ,wireless transmission is faster using NFC for ink screen

ShortcomingsOf course,the 4-color ink screen technology is more realistic and delicate than the traditional 3-color technology.However,we hope you can understand the shortcomings of the ink screen(Similar products that already exist or will be available in the future).The ink screen we use can display simple black and white pictures better, Obviously,it cannot compare the color,Pixel and clarity with LCD screen
