An electronic information display label and its usage method

Abstract

The invention discloses an electronic information display label, comprising an electronic display module, which is used for receiving information and displaying the information; an information receiving / sending module, the information receiving / sending module and the electronic display module It is used to receive information from the outside and then transmit it to the electronic display module, and the electronic display module performs information display. The information receiving / sending module can send request information periodically or periodically or manually to send information from the outside. The host acquires information; a power supply module, the power supply module is directly or indirectly connected with the electronic display module and the information receiving / transmitting module, respectively, and the power supply module provides necessary power for the electronic information display label; the present invention can It avoids primary and secondary waste of resources, and can get rid of cumbersome manual operations, which improves efficiency and greatly reduces costs.

Description

technical field [0001] The invention belongs to the technical field of electronic information, and relates to an electronic information display label and a using method. Background technique [0002] With the increasing awareness of environmental protection in the world, the resistance to waste of resources has gradually become popular. In many occasions, such as supermarkets, shopping malls, small stores, and places where information is marked, paper or other physical materials are widely used as carriers for information. The phenomenon of marking, on the one hand, this method requires a large amount of physical materials, such as paper materials, metal materials, etc. The use of these physical materials must be obtained through the mining and processing of natural resources, resulting in the use of primary resources and Waste, on the other hand, when the information identification with such physical material as the carrier needs to be modified or replaced, the same amount ...

[0002] With the increasing awareness of environmental protection in the world, the resistance to waste of resources has gradually become popular. In many occasions, such as supermarkets, shopping malls, small stores, and places where information is marked, paper or other physical materials are widely used as carriers for information. The phenomenon of marking, on the one hand, this method requires a large amount of physical materials, such as paper materials, metal materials, etc. The use of these physical materials must be obtained through the mining and processing of natural resources, resulting in the use of primary resources and Waste, on the other hand, when the information identification with such physical material as the carrier needs to be modified or replaced, the same amount of material will be consumed, resulting in further waste, which can be called secondary waste, and this The method of class modification and replacement will inevitably use a lot of labor, which also causes waste in cost. At the same time, the method of modification and replacement is relatively more cumbersome and clumsy, that is, inefficient
