Over the past few decades, electronic display technology has seen a significant evolution. LCD and infrared communication or RFID labels are no longer only used in the industry. Nowadays, electronic display technology is used in electronic shelf displays to showcase pricing, product features, etc.
We're going to examine the difference between E-ink , LCD, and RFID labels.
E-ink Labels (ESL)
Electronic Shelf Labels (ESL) are used by retailers to show product pricing on shelves. Every time a price is altered under the management of a central server, thus product pricing is automatically updated. Electronic display modules are frequently fastened to the leading edge of store shelves.
With technological advancement, ESL modules use electronic papers because it offers a clear display, support complete graphic imagery, and require no power to store images. When a product's price changes, the price display can be immediately updated thanks to a communication network.
This network of contact is what truly sets ESL apart and makes it a workable alternative. The wireless connection must be reliable and have a respectable range, speed, and battery life.
LCD Labels
ESL tags are displayed on liquid crystals in a manner akin to how numbers are shown on a calculator. Each number is represented by seven bars and segments on an ESL tag with a liquid crystal display. Based on activating various combinations of these seven bars and segments, the numerical value displayed on the tags themselves is subsequently displayed.
The difficulty of showing some letters on a liquid crystal display tag is a drawback. Diffused infrared communication is the method of connection between the transmitter and the label. Infrared is bounced off of surfaces to establish the values on the LCD tags. However, because each data packet from the transmitter is compressed, the transmission speed is severely hampered.
Radio Frequency Identification Labels (RFID)
Radio waves are used by RFID technology to transmit and receive data between a tag and a reader. At its most basic level, an RFID reader transmits a signal to an RFID tag, and the tag responds with a signal that carries information. Depending on the application, each individual RFID tag can be loaded with specific data, such as a GS1 Electronic Product CodeTM (EPC), before being attached to goods, cartons, pallets, or even expensive machinery.
Comparing RFID tags to barcodes makes them easier to understand. RFID tags are frequently used to quickly obtain product- or pallet-level information, much like barcodes. However, because RFID tags work with radio wave technology rather than a direct line of sight, they can read entire pallets or truckloads of goods at a rate of 700 goods per second.
Due to this, RFID tags have a distinct advantage when it comes to increasing supply chain visibility and efficiency, called smart label tracking. Beyond distribution and supply chain advantages, several brands are using RFID tags to interact personally with their customers, enabling them to scan the label to access product-specific landing sites and/or educational content.
ESL Vs LCD Vs RFID- Which is better?
To most retailers, e-ink shelf label is the best choice to invest in. The retail sector accounts for the majority of ESL's end users. Users span a wide range of industries, including grocery stores, hardware stores, sporting goods, furniture, home appliances, and electronics and gadgets. This anticipated growth can be attributed to the retail sector's growing use of ESL, which has been more widely available to chains of stores as a result of ESL's declining price over time.
So, what's your approach now?
