The patent is introduced

Technical field

The utility model belongs to the electronic equipment technical field, particularly relates to a kind of passive light-emitting circuit and electronic label。

Technical background

Because of the difference of antenna design, circuit design and circuit components selection and matching, the existing electronic tags are active luminescence, set with an external power supply or batteries, the circuit structure complicated, the production cost is high, bulky, unfavorable to the user to carry and use。 

Utility model content

In view of this, the utility model example provides a passive light-emitting circuit and electronic label, in order to realize the electronic label of passive power supply, simplify the circuit structure of the electronic label, reduces the production cost of the electronic label.
