What is the E paper Display?

E-Paper Display is an innovative method and technology for information display. Also known as an e-paper display or e-ink display, it is a reflective display technology that mimics the visual effects of paper, featuring low power consumption, eye protection, and clear readability even under strong light.

The structure of an E-Ink Display is composed of two substrates coated with an electronic ink composed of countless tiny transparent particles. The particles are formed by sealing many black and white particles with positive and negative charges inside liquid micro-capsules. Different colored charged particles will move in different directions due to the application of different electric fields, presenting a black or white effect on the surface of the display screen.

The working principle of EPD display

The E-paper screen is composed of a large number of micro-capsules, each containing positively charged white particles and negatively charged black particles (or colored particles)

When different voltages are applied, white particles move to the surface and display white; Black particles moving to the surface will display black; After the particle position stabilizes, the image can remain unchanged even if the power is turned off.

The Key Advantages of E-Paper Display

1. Ultra Low Power Consumption

Only consumes power when refreshing the screen, and the static screen can last for weeks or even months, making it very suitable for battery powered and wireless devices

2. Comfortable Eye Protection

No self luminous, no blue light, reading experience close to paper, not easily fatigued after long-term viewing

3. Excellent Visibility Under Strong Light

Reflective display, still clear and readable under direct sunlight, superior to traditional LCD and OLED

4. Power off Without Losing the Screen

Maintaining the final display content even after a power outage enhances system reliability and information security

5. Wide Working Temperature, Stable and Reliable

Suitable for indoor and outdoor environments, resistant to vibration, long lifespan, and low maintenance costs

Typical Applications of Ink Screen

1. E-Book Reader

2. Electronic Price Tag (ESL)

3. Smart meters (water meters, electricity meters)

4. Industrial instrument display

5. Smart Home Information Screen

E-ink display, with their significant advantages such as low power consumption, eye protection, strong light visibility, and power-off retention, have become an ideal choice for fields like e-reading, smart retail, industrial Internet of Things, and public information display. EDP are particularly suitable for application scenarios with low information update frequencies, long-term display requirements, and high battery life demands.
