Factory best selling Supermarket Price Tag Holder - Shelf price label holder supermarket tag holder clear PVC – Zkong

As the core of the system, the electronic price tag is favored by the combination of BLE module and electronic ink screen.

Electronic price tags, also called electronic shelf labels (ESL), are electronic display devices with information sending and receiving functions, and are mainly used in supermarkets, convenience stores, pharmacies, and other electronic labels that display price information.

In short, the electronic price tag is the part that the customer sees, the display material chooses the electronic ink screen, the network communication chooses the low energy consumption BLE module is the mainstream choice of the manufacturer at present.

In the selection of display materials, electronic ink screens are generally selected, not only because of the low cost of electronic ink screens, but also one of the main reasons for the material advantages of electronic ink screens. Take the zkong electronic price tag as an example to explain

First, zkong ESL is light in weight and small in thickness. The electronic ink screen is light in weight, small in thickness, and more robust and durable compared with ordinary LCD displays. This also determines that the electronic ink screen label has a certain degree of wear resistance and anti-collision performance, and has a long service life.

Second, high reflectivity and ultra-low power consumption. Normal displays need to use backlights to illuminate the pixels in order to see more clearly, and the electronic ink screen (electronic paper) is just like ordinary paper, it can reflect the light in the surrounding environment, and the reflectivity and contrast are very high. Use backlight, which greatly reduces energy consumption. At the same time, e-paper can retain the original text and pictures without the need for continuous power. This makes the static display of the electronic ink screen label no power consumption, long battery life, and power failure will not affect the price display.

Third, ZKONG uses a dot matrix electronic ink screen with high visual sensory comfort. It is generally believed that electronic ink screens are more suitable for reading than ordinary monitors, because the text displayed on electronic paper is fixed and does not need to be continuously refreshed. Just like ordinary paper products, the viewing angle is large. It is ideal for electronic paper to read in the sun. It will not darken because of the strong light map. Maintaining a stable and excellent display effect and creating a highly comfortable visual sense for consumers is also one of the reasons why electronic ink screen labels are favored by merchants.

In terms of network communication, taking into account the cost and application effect, zkong uses BLE protocol 5.0, and the range of communication modules is not large. Due to the high power consumption of WiFi, using BLE (BLE Low Energy Module) is a good choice, and it can run for several years with a button battery.

Therefore, the core components of zkong ESL are mainly electronic ink screens and control processors integrated with low-power BLE modules. This combination is cost-effective and functional.
