The display retains an image without power; once an image is formed, it can be preserved for extended periods even after power is removed, resulting in near-zero static power consumption.
Power is consumed only during screen refreshes. Static power consumption approaches zero, significantly extending the battery life of portable devices.
Readability improves in strong ambient light, as it relies on reflected ambient light rather than a backlight, offering excellent outdoor performance.
Eye-friendly and fatigue-free, with no backlight flicker or blue light emission, making it suitable for prolonged use.
Full-color e-paper has been achieved, as demonstrated by Samsung's Color E-Paper, with further progress in cholesteric liquid crystal and electrowetting technologies.
Capable of functioning across a broad temperature range, making it suitable for harsh environments; high domestic production rates have contributed to cost reductions.
Pixels are composed of microcapsules containing charged particles.
An applied electric field drives the directional movement of charged particles, thereby achieving black-and-white imaging.
Once particles are positioned, they maintain their state even when the electric field is removed, enabling persistent image display.
Energy is consumed only during the image refresh process; power consumption in static display states is near zero.
Imaging relies on ambient light, eliminating the need for a backlight, and offers excellent visibility under bright light conditions.
