スマートバス停に電子ペーパーソリューションを適用
AMT屋外用電子ペーパーソリューションの成功事例
22 Jan, 2025環境保護と省エネルギーへの世界的な関心の高まりに伴い、電子ペーパー（EPD）は公共機器用途でますます普及しています。電子ペーパーの最大の特長は低消費電力です。画像が変化する時だけ電力を消費し、静止表示時には電力を一切消費しません。この特性により、電子ペーパーディスプレイはスマートシティや屋外情報ディスプレイに最適な選択肢となっています。AMT顧客と協力して数々の課題を克服し、スマートバス停への電子ペーパーディスプレイソリューションの導入に成功しました。
Challenges of Outdoor Applications
ePaper displays installed outdoors are susceptible to weather and environmental factors, presenting several challenges to address:
- If air bonding is used between the cover glass and the ePaper display, outdoor reflections can affect the display performance of color ePaper.
- The operating temperature range of ePaper is 0°C to 50°C. Under outdoor conditions, prolonged sunlight exposure can cause the temperature to rise, preventing the ePaper display from refreshing properly.
- ePaper displays are not UV-resistant. Prolonged UV exposure over several months can cause the ePaper to yellow or crack.
- Since ePaper displays do not have a backlight, screen content becomes unreadable at night.
Comprehensive ePaper Solutions
To address these issues, AMT has developed a complete ePaper display solution with optimized technology and design:
- 光学貼合 is used between the ePaper display and the cover glass, reducing reflectivity and enhancing display performance.
- IR cut films are applied to reduce the temperature under sunlight, ensuring the ePaper display remains functional.
- UV-resistant designs are incorporated to protect the ePaper display from UV damage, meeting ASTM G154 Cycle 1 - 1,000 hours and MIL-STD-810H Pro 1 - 1,000 hours testing standards.
- Front light guides are added to make screen content visible even in environments without light sources.
