ePaper Digital Smart Bus Stop Sign
AMT Green ePaper Display Solutions
27 Aug, 2025To mitigate global warming and ensure the sustainable use of Earth’s resources, energy saving and carbon reduction have become top priorities for many enterprises. Green displays (ePaper or EPD) feature low power consumption. Unlike traditional LCDs, ePaper only consumes power when changing images, while static images can remain for a long time without energy use. This makes them ideal for applications requiring long-term display of fixed information. At the same time, ePaper uses reflective display technology, which allows it to be clearly visible without a backlight—the stronger the ambient light, the clearer the screen. With the maturity of color ePaper technology, the application scope has expanded to outdoor information boards, medical equipment, bus stop signs, and digital signage. AMT’s ePaper solutions provide diverse customization options to help customers overcome challenges in adopting ePaper products and meet the needs of different industries.
Pain Points of ePaper Products
AMT provides multiple countermeasures and value-added protections for ePaper displays, enabling them to be successfully applied in various fields. Common challenges of ePaper include:
- Insufficient UV resistance: Months of UV exposure can cause ePaper to yellow or crack.
- Poor night visibility: Without a backlight, ePaper is difficult to read at night or in low-light environments.
- Structural fragility: ePaper panels are relatively thin and can be easily damaged by pressure or impact.
- Moisture Ingress: If moisture penetrates the internal materials of the ePaper, it may cause ghosting and slow down the response time.
- Inconvenient operation in wet environments: When integrated with touch functions, PCAP buttons on ePaper can easily cause false touches in wet conditions.
AMT’s Technical Highlights
AMT provides value-added technologies for ePaper to overcome these challenges, expand application areas, and deliver comprehensive solutions:
- UV protection: Long-term shielding against UV damage, compliant with ASTM G154 Cycle 1 - 1,000 hours and MIL-STD-810H Pro 1 - 1,000 hours test standards.
- Front light guide: While typical front light guides offer about 50% uniformity, AMT’s front light guide achieves up to 70% uniformity. Combined with low-power light bars, it ensures visibility in low-light conditions with uniform brightness.
- Optical bonding technology: We use silicone-based OCA to bond cover glass or touch panels on top of ePaper, protecting the panel from damage and preventing moisture ingress.
- Water-resistant button integration: Aqua Switch touch buttons can be integrated into the display frame, allowing accurate operation even in rain or humid environments.
Innovation and Features
AMT’s ePaper display solutions combine optical bonding, touch integration, and highly durable materials to deliver stability and reliability:
- Optical bonding sizes up to 42 inches, meeting large public information display needs.
- Complete touch solutions: Integration of touch panels, controllers, firmware, and drivers with ePaper for one-stop customer support.
- Optical bonding using Lucent Gel OCA, highly weather- and UV-resistant, suitable for harsh environments.
- Advanced ink printing on cover glass prevents peeling or discoloration during long-term outdoor use.
