Epaper Applications and advantages:
The application scenarios of e-ink screen in B-end are mainly manifested in various e-paper label products and information bulletin boards, and the application scenarios cover smart retail, smart office, smart warehousing, smart factory, smart medical, digital finance, etc., which can meet the needs of paperless, intelligent, digital, energy conservation and emission reduction, and have continued to grow rapidly in recent years. At present, e-paper labels are the products with the largest shipments of e-paper applications, and according to Lotu technology data, the shipment growth of e-paper label modules is expected to exceed 100% in 2022. From the perspective of downstream applications, smart retail will be the largest application scenario in 2021, accounting for 87%.
►Smart retail: Electronic shelf label (ESL) is an important application of electronic paper in the field of smart retail, which can replace the traditional paper price tag to achieve information display function, and can remotely modify price and other information with one click. Benefiting from the increase in the number of convenience stores brought about by new retail, as well as the improvement of the intelligence of newly opened convenience stores, we expect the demand for ESLs to continue to grow in the future.
►Smart office: The application of e-ink screen in the office field mainly includes e-seat cards, e-paper door numbers, e-paper office cards, e-paper handwritten conference books, etc. During the Beijing Winter Olympics, the badges worn by volunteers were made of e-paper materials, and BOE supplied a 3.7-inch black, white and red e-ink screen, which can be connected to the mobile app through NFC to quickly modify the graphic content. With the increase in the demand for paperless office and the demand for intelligent IoT, there is an obvious alternative space for e-paper in the field of traditional paper office materials.
►Smart logistics: The application of e-paper in the field of logistics is mainly express delivery bills. From 2020 to 2021, e-paper was applied in batches in SF's cage tracking and positioning management system, and E Ink also launched The Box, which uses e-paper as the information display interface for packaging boxes, which can effectively reduce the use of paper labels, and at the same time, with standardized recyclable logistics boxes, it can significantly promote the digital upgrade of environmental protection and logistics. In addition, the e-paper sheet enables better tracking and management of goods through the integration of accelerometers and mobile communication.
►Smart factory: Similar to the retail field, the use of e-paper in the factory is dominated by electronic price tags. In 2020, Chuanqi Optoelectronics created an e-paper production demonstration project based on UWB indoor positioning technology, providing a new digital and paperless intelligent workshop solution, which promoted the improvement of factory efficiency.
►Smart medical: The application of e-paper in the field of smart medical care is mainly e-paper bedside cards, bed cards, nursing cards, infusion cards, ward door cards, drug inventory management labels, etc. The application of e-paper plays an important role in the digital transformation of smart wards and wards, and is an important part of digital transformation, which can improve the efficiency of information release and interaction.
►Smart transportation: the typical application is the bus electronic stop board and information display board, which is the same as the traditional LCD screen electronic bus stop board, can realize the line, vehicle real-time station, but compared with the traditional LCD screen stop board, the use of electronic paper stop sign can meet the energy supply demand through solar energy, road management and low-carbon emission reduction are of great help.
►Electronic billboards: According to Yuantai Technology, if 30 million 10-inch electronic billboards are used worldwide for 5 years, the electricity consumption of e-paper billboards can be reduced by 12,000 times compared with the electricity consumption used by LCD billboards. Compared to single-use printing paper, CO2 emissions can be reduced by 60,000 times.
►Digital finance: Typical applications are digital currencies, such as card-type digital wallets, which are similar to the visual UnionPay cards launched by UnionPay in the early days.
The application of electronic ink screen has room for promotion, and the application field of e-paper has been further expanded under the joint development of multiple manufacturers. We expect that in the future, with the acceleration of cooperation between e-paper manufacturers, e-paper is expected to break the application bottleneck in some fields and further expand the commercial market share.
Consumption: Mainly consumer electronics, involving a variety of devices such as readers, tablets, computers, and wearables
Consumer electronics terminal applications are an important market revenue for e-ink screens. In 2021, the revenue share of the e-ink screen market was split by end user, with consumer electronics terminals accounting for 53.7%, retail terminals accounting for 23.9%, institutional terminals accounting for 13.8%, and other terminal users accounting for 8.6%. We believe that consumer electronics terminal applications may continue to maintain an important position in the revenue of the e-ink screen market in the next few years.
