In retail stores, electronic shelf labels are becoming prevalent. ESLs let stores easily update product prices, stock levels, and other info digitally. It’s done remotely from a main control system instead of having to print and swap out paper labels by hand. There are two basic types of ESLs – ones using e-paper displays and LCD ESLs. E-paper display ESLs use electronic ink technology to show info and run on batteries, while LCD electronic shelf label systems have liquid crystal display screens and need outside power.
How E-paper and LCD ESLs Work
E-paper ESLs work using electronic ink technology. Tiny microcapsules inside contain either negatively charged or positively charged particles suspended in a liquid. During updates, an electric field is applied, and the particles either rise or sink, displaying certain colors. This achieves the desired image. Without power, the image stays due to mechanical color change within each capsule. This allows e-paper displays to use little energy and stay visible indoors or outdoors.
LCD ESLs use liquid crystal display technology. Two glass panels arrange liquid crystal molecules. The panels contain electrodes that apply electric currents. During operation, the currents control molecular orientation to allow light through in various intensities. Behind the crystal layer lies a backlighting unit. Together, these projects color images onto the label.
E-paper and LCD ESLs: The Comparison
Electronic shelf label solutions based on E-paper display and LCD screens have their own advantages and limitations. The following aspects highlight their key differences:
- Technology
As described above, E-paper ESLs use electronic ink technology powered by batteries, while LCD ESLs use liquid crystal displays requiring external power. This fundamental difference impacts other factors such as size, energy use, and capabilities.
- Size
E-paper electronic shelf label solutions available in the market are smaller in size owing to their battery operation, typically ranging from 2-6 inches. LCD ESLs can be bigger as they are externally powered and available in sizes from 4 inches up to 15 inches or larger.
- Display Options
E-paper ESLs only support static displays of limited colors, typically white and black, whereas LCD ESLs enable full-color graphics and animations. This allows LCD models to showcase products and marketing messages in a more vivid and visually appealing manner.
- Energy Consumption
E-paper ESLs consume very little power as they only draw power during content updates, while LCD screens constantly use power whenever switched on. For locations where external power is inconvenient, e-paper electronic shelf label models may be preferable to minimize ongoing energy costs.
- Readability
Both are generally very clear to read. E-paper reflects ambient light better for readability in bright surroundings. LCD screens can sacrifice visibility at extreme viewing angles depending on location and purpose.
Comparison Highlights
| Specification | E-paper Display ESLs | LCD ESLs |
| Technology | Electronic ink/Passive matrix | Liquid crystal displays/Active matrix |
| Size | Generally smaller (<6 inches) | Can be larger (6-15 inches) |
| Display | Black and white/Two color | Full color |
| Power Consumption | Very low | Moderate to high |
| Readability | Excellent outdoor readability | Good, but visibility reduces at extreme angles |
