NFC E ink Screen DIY iPhone Case for 13 14 15 13pro 14pro 15pro 13pm 14pm 15pm

      external connection wires or tail plugs are needed. By using NFC coil coupling technology, the main control program can be driven to achieve data transmission and clear display of the transmitted content. No built-in battery or Bluetooth connection is required, and the pictures on the phone case can be changed at any time, truly achieving wireless transmission.

      case, ink screen back panel, and phone frame are designed with a separate structure, allowing users to not only change the pattern on the ink screen at will, but also change the frame of the phone case according to their personal preferences. This truly enables "endless customization."

      phone case only absorbs a small amount of power from the phone through NFC when transmitting new pictures, and the ink screen display pattern does not require power to maintain after transmission. The working principle of the ink screen: the ink capsule molecules are pushed to different positions by the control of positive and negative charges, and when the current stops, the ink capsule molecules are fixed in the current position. Therefore, the screen shows that there is no need for power maintenance, and the overall demand for mobile phone power is very small, almost negligible.
