Shield efficiency high, not error-prone.
Current electronics paper label, is made, electronic paper technology, electronics of NFC technology and electronic paper screen
Paper is a kind of special display screen, with ultra-thin, it is rewritable, be easy to carry, power off when can also keep display etc. characteristic.Electricity
Sub- paper technology mainly have six kinds of different types of technologies including E-Ink microcapsules technologies, SiPix micro-cups technology,
Bridgestone electronics liquid powder technology, cholesterol liquid crystal Display Technique, micro electro mechanical system (MEMS) technology, electric moistening technology.）
Current electronics paper label is used mostly battery for Electronic Paper is tag-powered, needs within general 3 to five years to change once
Battery, can increase use cost, and the life-span of label is restricted, and then develop the electronic tag of non-contact power, without making
With battery, use time is longer, but, this voltage being powered by single coil is not sufficiently stable, electric current is not big enough, is had
When can cause the label cannot normal work.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of near-field communication and can stabilization continued power supported
NFC electronical display cards.Therefore, the utility model uses following technical scheme：
NFC electronical display cards, including electronic paper screen, Electronic Paper drive module, power supply module, processor；Its feature exists
Coupling coil is additionally provided with the electronical display card；The coupling coil and processor are connected, to transmit signal；The coupling
Coil is also connected with power supply module, to provide power supply；The power supply module and processor and the connection of Electronic Paper drive module, to carry
For operating current, the electronic paper screen is connected with Electronic Paper drive module.
Further, the coupling coil is 13.56 MHz coupling coils, and the 13.56 MHz coupling coils are 4 in
The mode of outer 2 circle of circle is coupled, and interior 4 turn coil carries out matching centre frequency to 13.56MHz by electric capacity C1, outward 2 turn coil
