Description

An ink screen mobile phone case based on a separate NFC antenna

Technical Field

The utility model relates to the technical field of mobile phone shells, and in particular to an ink screen mobile phone shell based on a separated NFC antenna.

Background Art

Mobile phone cases are decorations that protect or decorate the appearance of mobile phones. Electronic ink screens are a new method and technology that innovates information display. Like most traditional inks, electronic ink and the circuits that change its color can be printed on many surfaces, from curved plastics, polyester films, paper to cloth. The difference from traditional paper is that electronic ink changes color when powered on, and can display changing images like traditional screens. Existing ink screen mobile phone cases usually use a separate power supply method and need to be charged after a period of use. In this way, they have a certain degree of non-deformation during use. At the same time, the charging structure of the mobile phone case will increase the thickness and weight of the mobile phone case. The main purpose of the mobile phone case is to protect the mobile phone. The increase in thickness and weight brings inconvenience to carrying and using, and also affects the aesthetics.
