Description

Dot matrix passive electronic label system

technical field

The utility model belongs to the industry of electronic technology and equipment manufacturing, in particular to a dot-matrix passive electronic label system.

Background technique

Most of the existing supermarkets, warehouses and other occasions use paper labels. Paper labels have the disadvantages of consuming manpower, material resources and error-prone, and are not environmentally friendly. The e-paper display has bi-stable characteristics (bi-stable), that is, it only consumes power when changing images, but does not need to consume any power when displaying still images. The e-paper display uses reflected ambient light to allow viewers to see the displayed image clearly. It has a high contrast ratio and a wide viewing angle of 180 degrees. It is ultra-thin, reusable, and environmentally friendly. It is very suitable for replacing paper labels.

A small number of supermarkets have adopted 2.4GHz wireless, active electronic paper display electronic labels with dot matrix display mode to replace paper labels, but the cost of the labels is very high.

Wireless tags usually use two to three button batteries. After one or two years, the battery power of the tag is gradually exhausted and needs to be replaced by a special person, and the discarded batteries are not environmentally friendly. In addition, wireless tags must be controlled by a base station, and the base station covers a limited distance. A base station needs to be installed every 5 or 6 meters, and the cost is relatively high. In addition, the electromagnetic environment is complex now, and the 2.4GHz frequency band is easily interfered by signals such as WIFI, which often causes the wireless tag to lose connection with the base station, resulting in the failure to update the product price. The installation and commissioning of the entire system using the wireless tag is also relatively long, usually about a week. After that, professional and technical personnel are also required for long-term maintenance. As a result, wireless tags cannot be popularized on a large scale. Small supermarkets, convenience stores, etc. are even more unaffordable.
