Advantages of E-Paper (E-Ink) Display Technology
The E-Paper Display uses microcapsule electrophoretic technology to display content. This technology works by applying an electric field to charged particles suspended in clear fluid, causing the microcapsule to become visible by reflecting ambient light, just like traditional printed paper. Some of the benefits of this technology are:
- Clear display without electricity: Display content is clearly visible under lamplight or natural light without a backlight
- Wide viewing angle: Offers nearly up to 180° viewing angle
- Paper-like effect: Often used as an e-reader due to its resemblance to traditional printed paper
Possible Applications
- Shelf label: Suitable for displaying product information, pricing, and promotions
- Industrial instrument: Ideal for displaying measurements and data in a wide range of industrial applications
- E-reader: Perfect for reading e-books and other digital content with a paper-like effect
- Smartwatch: Can be used to display notifications, time, and other relevant information on a smartwatch screen
