In response to the global emphasis on corporate ESG and energy conservation and with the rising demand for portable displays, the need for energy-efficient, low-power consumption displays is increasing. WINSTAR is promoting electronic paper display (EPD) technology, which offers high energy efficiency,saving characteristics and a comfortable visual experience, making it a market focal point. EPDs, like regular paper, rely on ambient light reflection, providing a comfortable reading experience and maintaining clarity even under direct sunlight. With a wide viewing angle (theoretically 180 degrees), EPDs offer better contrast than other display technologies, comparable to or better than print quality. There are many types of EPDs, and this article introduces the technology principles, applications, and advantages of WINSTAR electrophoretic EPD.

E-paper Display Technology Principles:

E-paper Display (EPD) technology, also known as electronic ink display technology, relies on microcapsule technology. The basic structure of an EPD includes millions of tiny capsules, each containing two types of electrophoretic particles: negatively charged white particles and positively charged black particles, suspended in a transparent fluid.

• Electrophoresis: When an electric field is applied, the corresponding black or white particles move to the top of the microcapsule, making the area appear black or white to the user. This is achieved by utilizing the charged particles and the principle of attraction under an electric field.
• Bistable Technology: By supplying electrodes with positive and negative electric fields, the charged black and white particles move and align according to the attraction principle of different charges. After removing the electric field, the particle arrangement remains unchanged, keeping the image constant. When updating the image, a different electric field is applied to the electrodes, causing the particles to move again, resulting in a screen refresh. The new electric field pattern rearranges the black and white particles, updating the display.

• Wide Viewing Angle: Provides a better visual experience.
• Multiple Color Options: Including black and white, three-color, and four-color options.
• Sunlight Readable: Suitable for outdoor use.
• Touch Options: Available in touch panel models.
• Front Light Options: Adaptable to different lighting environments with front light options.
• Customization Services: Meets various sizes and custom FPC requirements.
• Technical Services: Professional team offering fast and efficient services.
• After-Sales Service: Comprehensive technical support and after-sales service.

EPD technology focuses on energy-efficient displays, offering significant energy-saving advantages. EPD displays provide advanced technology and diverse applications, delivering efficient, energy-saving, and environmentally friendly solutions. These displays have become a preferred choice in the market for various uses. Whether for everyday applications or professional settings, energy-efficient EPD technology continues to offer valuable and innovative solutions.
