As the cost of liquid crystal display and controller drops significantly, under the promotion of the concept of green environmental protection, supermarkets in developed countries begin to use electronic labels to replace the traditional paper labels. So far, about 25 million supermarkets around the world have put electronic labels into practical use. It is mainly distributed in Europe, America, Australia, Turkey in the Middle East, Japan and South Korea in Asia, etc. The introduced retailers include Metro, Migros, 7-ELEVEN and so on. China's huge retail supermarkets also have huge market potential.

      European supermarkets require that the battery cannot be changed for 3 to 5 years, while the domestic requirement is that the battery cannot be changed for 1 year. Ordinary LCD screen with backlight, a button battery in less than 3 months will run out, do not play the backlight is completely invisible. If you use E ink, the effect is very good, but the price is too high.

      At present, the supermarket electronic label technology mainly has infrared ray, microwave radio, low frequency radio, fluorescent lamp modulation transmission four forms. The radio frequency used is in the range of 15×15 as a transfer base station, which is usually in a dormant state. When there are data changes, the radio frequency circuit is opened to receive signals.

      Now the cost of electronic labels, to calculate the amount of 50K, electronic ink program is about $15, the general liquid crystal program is about $10, compared with the traditional paper label, the cost is still higher. Due to the cost, it is still not possible for ordinary hypermarkets in China to use electronic labels. However, it will be more acceptable in some high-end convenience stores, imported commodity supermarkets, hotel supermarkets and other retail outlets that are not so sensitive to prices, which will be of great help to the image and brand of supermarkets. In addition to the environmental protection factor of saving wood, the most advantage of electronic shelf labels is that a computer system can be used to control the content of the product name and price display, which eliminates the problem of manual writing errors. At present, the government still imposes heavy penalties on the wrong price labels. Paper labels typically have a 6% replacement error rate and a 2% label loss rate, and the administrative penalties associated with these errors are actually a hidden administrative cost. The supermarket wirelessly transmits the product information and price to the electronic label through the management system in the store, which can reduce a large amount of labor, which is very attractive in developed countries with high labor cost. Due to the low labor cost in China, the demand for automatic system is not high enough, but due to the substantial rise in domestic labor price in recent years, The demand for automated systems will rise dramatically.

     In addition to the product name, price and bar code, there is also an identification area, which is reserved for the supermarket merchants to develop advertising space, because the cost of electronic labels is still relatively high. If advertising can be used to share the cost of electronic labels, or even make profits, a new business model can be generated. At this time, the value of the electronic label is far more than a tool to prompt the name and price of the product, but become a window for brand display. If you can take this step, the cost disadvantage will be negligible.

      Low cost will be the goal that all ESL manufacturers always pursue in the future. The competition among all manufacturers is mainly reflected in the competition of core technology. The company that breaks the bottom line of cost will have the greatest advantage in the future ESL market.

Although ESL is close to its cost bottom line, it is expected to fall further with the spread of applications and the development of related technologies and processes.

      Weifeng Technology company through the introduction of relevant equipment, improve the relevant process, expand the production capacity of ESL, for the application of ESL opened the door to popularity.
