Application of electronic ink screen in modern logistics and warehousing

 

 

The general process of logistics transportation: the consignor—the distribution center where the consignor is located—road/air/water transportation—the distribution center where the consignee is located—the secondary distribution center in the area where the consignee is located—the consignee.

After the goods arrive at the logistics storage center at the receiving place, the sorting personnel need to first check the quantity of the arriving goods, then classify the goods according to the type, and finally sort the goods according to the administrative district or street where the receiving place is located. After the secondary classification, it is temporarily placed on the shelf.

At present, most logistics centers are still managed by making material cards on each shelf, sticking printed labels, or even matching numbers with inspection forms. This traditional approach has many drawbacks. First, handwritten or printed material cards and labels need to go through two manual processes of manual input and manual posting, which greatly increases the incidence of errors. Second, because the material of the printed card is mostly paper, the text on it is easily contaminated or damaged. Once the display is unclear or the reading is wrong, the goods will be wrongly sorted, causing a series of troubles in subsequent transportation. Third, the logistics and storage center usually covers a large area. When there are goods in and out of the warehouse, such information registration method causes the staff to run back and forth all the time to do information identification and modification work. security risks.

After some attempts by modern logistics centers, it has been proved that the use of electronic ink screens instead of traditional labels, checklists and other forms has many advantages:


Simple construction, cheap and durable

The phenomenon principle of the electronic ink screen is much simpler than that of the electronic display screen. It does not require a high-density array of light-emitting diodes, and only needs a combination of microcapsules, ink and screen film. Therefore, the electronic ink screen must be cheaper than the ordinary electronic display screen. According to statistics, a city-level modern logistics storage center in a first-tier city can handle as many as one million pieces of goods a day. These goods require tens of thousands of shelves. Generally speaking, each shelf is divided into three to four parts. Layers, each layer requires two labels, and the total demand for labels will reach the level of 100,000. If the cost of such a large demand is too high, it will be unbearable for the operators of the logistics and storage center. In addition, e-ink screens with simple structural principles will also last longer in terms of service life. Ordinary electronic display screens use light-emitting diodes as the basic structure, and their lifespan is limited. When they are used for display in storage centers, they need to maintain continuous light, and the lifespan will be reduced. And this problem does not exist for the e-ink screen, because the e-ink screen can completely cut off the power supply after applying an electric field to display the image, and theoretically can maintain the image for several years, during which no structure and ink will occur. loss. To sum up, compared with electronic display screens, electronic ink screens can greatly save equipment procurement and use costs as shelf labels in logistics and storage centers.

Easy installation and reliable display

The demand for label displays in modern logistics and warehousing centers is huge, and ordinary electronic displays usually need to provide power because they require continuous power supply, and large-scale power supply not only consumes a lot of costs in the early construction and design stage, The exposed power cord will also cause great trouble for the past staff to sort and sort out the goods. In addition, another very big hidden danger is that the electronic display screen requires continuous power supply. Once the power supply failure or power outage occurs in the warehouse, the display screen will not be able to display any information immediately, resulting in the stagnation of sorting work or even The paralysis of the entire logistics system has unimaginable consequences. In order to avoid such a situation, some storage centers that use small electronic video screens have to use traditional labeling methods for shelf identification or set up backup power sources or batteries, resulting in the burden of the system. However, the display principle of the e-ink screen can well avoid this risk. The display principle determines that the e-ink screen only needs to consume power at the beginning of imaging, and can be displayed for a long time without power in the future. Therefore, the e-ink display usually Only one battery needs to be installed to work normally for months or even years, completely solving the problem of power supply.

Protect eyesight and save energy

The advantages of the e-ink display and the ordinary electronic display have been explained in the descriptions of the previous two paragraphs. However, at the beginning of its invention, the electronic ink display screen has been recognized by the market because of its non-eye-injuring characteristics. Therefore, it has to be mentioned that its display effect close to that of paper can protect human eyesight. In addition, another advantage of the e-ink screen is energy saving. As mentioned above, the image display of the e-ink screen only needs to consume electricity during the initial application of the electric field, and the subsequent display is a pure physical process that does not consume any electricity, which requires tens of thousands of modern warehousing and logistics centers for the display. It is also a small cost. At the same time, the use of the electronic ink screen also saves a lot of equipment maintenance and debugging during the use process, and saves labor costs.

Application development trend of electronic ink screen in logistics and warehousing industry

Production cost and display quality are further optimized

The core of the structure of the e-ink screen is the ink and the microcapsule. The ink is the conventional dye ink. There is no technical breakthrough point at present, but the size of a single microcapsule of the e-ink display has been continuously optimized. The size of this microcapsule can be The size of a single light-emitting tube in an electronic display is analogous. The smaller the size of the microcapsule, the higher the density of the microcapsule in the display of the same size, and the higher the fineness of the image display. Therefore, with the continuous development of nanotechnology today, the future electronic The size of the ink display microcapsules will also become smaller and smaller, and the display effect will become more and more delicate. At the same time, with the further advancement of industrial production intelligence and automation, the production efficiency of e-ink screens will be further improved to solve the low-yield problem that causes the current high prices of e-ink screens.

At the same time, the refresh rate of the e-ink screen will also be greatly improved. The display principle of the electronic ink screen is to apply an electric field to the microcapsules that need to be displayed, so that the charged ink in it moves to the surface of the film to complete the coloring. In this process, the operation unit of the display screen needs to firstly rasterize the image to be displayed according to the screen microcapsule density, and then transmit the command to each microcapsule, and wait for the electric field to finally complete the image display. Compared with the optical signal transmission of the electronic display screen, the development process of the electronic ink screen is complicated and slow, which leads to the low refresh rate of the electronic ink screen. This is also the reason why the reading experience of the early electronic reader has been criticized. one of the main factors. However, with the improvement of the computing power of electronic chips and the reduction of production costs, coupled with the innovation of electrophoresis technology, the refresh rate of the electronic ink screen in the future can completely reach a level comparable to that of the electronic display screen.

Further strengthening of application breadth and depth

At present, the application of e-ink screens in modern logistics warehousing and freight centers is almost entirely concentrated in the single field of logistics shelf label display. will be further expanded.

In terms of application depth, with the development of e-ink screen technology, color e-ink screens and handwritten e-ink screens have officially entered the market, giving the modern logistics and warehousing industry more possibilities for use. For example, the color e-ink screen is used to intuitively divide the area of ​​the goods through different colors, so as to improve the efficiency of sorting and identification. Another example is to add a handwritten electronic ink screen next to the ink screen that displays the label for sorting personnel to mark when sorting or checking goods to improve work efficiency.

In terms of application breadth, under the background of the country's increasing requirements for energy saving and emission reduction in the logistics industry, with the emergence and development of color e-ink screens, a large area of ​​e-ink screens will be used in the future logistics and storage centers to replace the original ones used to display logistics. The electronic display of information has become the general trend [3]. Even placing e-ink screens in promotional locations such as logistics distribution vehicles and billboards saves energy from losses caused by frequent replacement and reduces costs.

E-ink screen display information interconnection is more intelligent

The combination of e-ink screen and logistics Internet will be an important trend in the future. Speed ​​and accuracy are the life of today's logistics industry. For this reason, the logistics centers of some large-scale leading logistics companies have begun to build a comprehensive network of logistics centers, using the powerful computing power of electronic computers to sort and schedule goods. Under such a trend, the e-ink screen labels on the shelves are bound to need to connect and communicate with the Internet system of the logistics center. By implanting wireless receivers that receive information in the e-ink screen, the Internet of Things industrial labels can replace paper labels. While displaying the information, the display screen and the information system can be seamlessly connected. Through the Internet of Things industrial electronic label, the material information in the production process can directly interact with the enterprise information management system. Simultaneously update and modify shelf label management information, which is simple and convenient, improves work efficiency, reduces labor costs and the probability of human error.
