Description

Passive electronic paper shelf label system

Technical Field

The invention relates to the technical field of electrophoretic display, in particular to a passive electronic paper shelf label system.

Background

Shelf labels are generally installed near goods corresponding to shelves and used for marking prices of the goods and other information of the goods, and paper labels are mostly adopted in the market at present. Under the condition of using paper, when commodity information is frequently changed, a large amount of human resources and time resources are consumed, and the error rate is high. According to statistics, the time for manually replacing one price tag is at least two minutes, the tag loss rate is 2%, and the error rate is one ten thousandth to five ten thousandth. Paper price tags also involve labor costs for paper, ink, printing, and the like. In addition, in the case of paper price tags, the price change efficiency leads to price "fraud" caused by the price tag of the goods and the price of the cash register system not being uniform.

Electronic Shelf labels (ESL, electronic Shelf Label System) are used as an Electronic display device for replacing traditional paper price labels, each Electronic Shelf Label is connected with a data base of a computer in a shopping mall through a wired or wireless network, and latest commodity prices are displayed through a screen on the Electronic Shelf labels. The electronic shelf label brings the shelf into a computer program, so that the condition of manually replacing the price label is avoided, and the price consistency between the cashier desk and the shelf is realized. The electronic shelf label system is quick and timely in price change, can finish price change of tens of thousands of price tags in a short time, can increase the price change promotion frequency by simultaneously finishing the butt joint with the cash register system, increases 3% of sales amount after replacing the electronic price tags according to statistics, and has the price change error rate of 0.00001%. The electronic paper applies electrophoresis technology, namely, the principle of electrophoresis in colloid chemistry is utilized, charged pigment particles are stably dispersed in a non-aqueous dispersion medium containing dye, so that the dispersed phase and the dispersion medium present contrast, and charged pigment ions move to the surface of an electrode under the action of an electric field to display an image. Compared with a liquid crystal display shelf label, the electronic paper shelf label application manufactured by the electronic paper technology has a bistable characteristic (bi-stable), namely, the electronic paper shelf label application needs to consume power only when a picture is changed and does not consume power when a static picture is displayed. And has the characteristics of high contrast, wide viewing angle of 180 degrees, light and thin module thickness, reusability, environmental protection and the like.

However, there are still many problems with most electronic shelf labels on the market: first, these electronic shelf labels require batteries to supply power, and when the batteries are exhausted, they need to be manually replaced, thereby increasing the cost. If the replacement is not performed in time, the electronic tag is corroded by the outflow of the battery liquid, and the discarded battery causes environmental pollution if not properly disposed. Secondly, base stations are needed, which are limited by the coverage distance of the base stations, and are installed every 5 or 6 meters, and the base stations also need to be maintained, which further increases the cost. Moreover, easily receive electromagnetic interference, today of the high-speed development of science and technology, electromagnetic environment is complicated, and the 2.4GHz frequency channel is easily caused by signal interference such as WIFI to lose the antithetical couplet, and then the condition that the label content lost or can't in time update takes place easily. Finally, the debugging takes a long time, the system needs about one week for installation and debugging, and the base station, the tag and the system need to be tracked and maintained for a long time, which increases the labor cost. The above problems need to be solved.

Accordingly, it is highly desirable to provide a passive electronic paper shelf label system that does not require either a battery or a base station. In order to solve the above problems, the related manufacturers have tried to solve the problems without diligent attention, but it has not been known that suitable designs have been developed and completed for a long time, and there is no appropriate method for solving the above problems in general, which is obviously a problem that the related manufacturers want to solve. Therefore, how to create a passive electronic paper shelf label system is one of the important research and development issues, and is also an object of improvement in the industry.
