What is E Ink Display?
E Ink Display is a low-power, bistable display technology that simulates the visual effect of paper. It works by controlling the movement of charged particles inside the micro capsule through an electric field to form stable text or images. It can maintain the content to be displayed without continuous power supply, hence the name “E Ink Display”.

What are the feature of E Ink Display?
- Electronic paper offers awide viewing angle and no color distortion: E Ink Display boasts an ultra-wide viewing angle of nearly 180°, ensuring that the displayed content remains clear and transparent from any angle, with consistent display effects and no color distortion.
- E Ink Display’s paper-like effect reduces eye strain: E-paper uses ambient light reflective display technology, requiring no backlight, emitting no blue light, and flicker-free, producing no glare even in bright light. EPD simulates real paper, making it less likely to cause visual fatigue even after prolonged viewing.
- E Ink Display has low power consumption and long standby time: E-paper only consumes power when refreshing content, and consumes almost no power in static display mode, achieving long standby time.
- Electronic paper display is lightweight, portable, and flexible: E Ink Displayboasts ultra-thin and ultra-light physical characteristics. Some products support flexible bending, allowing E-paper to adapt to complex installation scenarios.
- E InkDisplay boasts strong interface compatibility and convenient development: Electronic paper comes standard with SPI interface support, enabling it to quickly adapt to MCU development platforms and reducing project development difficulty.
- EPD has a wide range of applications: it is widely used in fields such as smart shelf labels, industrial instruments, and medical equipment.
What is the core difference between E Ink Display and traditional screens (LCD/OLED)?
| contrast | E Ink Display | LCD | OLED |
| Display principle | reflective (particle movement) | transmissive | self-luminous |
| Power consumption | Extremely low power consumption (only for refreshing) | medium | medium to high |
| Visual experience | Paper-like, no blue light, clear even in strong light | it has blue light, strong light, and reflection. | the colors are vibrant, but they can easily cause eye strain. |
| Power off display | keep content | black screen | black screen |
| Refresh speed | slower | fast | extremely fast |
In summary, E Ink Display excels in “eye protection + low power consumption + static display”, while traditional screens excel in “color + dynamic display + refresh rate”.
FAQ about E Ink Display
1.Q: Are ghosting and screen flickering on E Ink Display screens a quality issue?
A: No! This is a normal characteristic of E Ink Display.The ghosting is caused by some e-paper particles remaining in their original positions after movement. The flickering is caused by a “full screen reset” during refresh to clear the ghosting; this resets all particles back to their original positions and then rearranges them, resulting in a brief flickering (black or white flicker).
2.Q: Can E Ink Display be used in direct sunlight?
A: No. Direct sunlight will cause the charged particles inside the E Ink Display to dry out and become inactive. This damage is irreversible. Strong light environments must be avoided, and the temperature and humidity requirements in the specifications must be followed.
