E-Paper
A reflective display technology that uses the principle of microcapsule electrophoresis. It consumes power only when the page is turned, with extremely low static power consumption, relies on ambient light for display, and is readable in sunlight without causing glare.
Timeline (last 90 days)
Electronic paper only consumes power when turning pages; the image is retained after power is cut, static power consumption is almost zero, and it is a reflective display that relies on ambient light rather than a backlight to emit light.
Electronic shelf labels (ESL) are the largest commercial market for electronic paper besides readers, with a single coin cell battery lasting several years.
The physical working principle of e-paper is controlling the position of black and white charged particles within microcapsules via an electric field.
Temperature significantly affects the movement characteristics of electrophoretic particles; at low temperatures particles move slower and require longer drive pulses, while at high temperatures particles move faster and may cause overshoot.
Temperature significantly affects the movement characteristics of electrophoretic particles, and the driver program needs to select the corresponding waveform table based on the current temperature.
Each frame in an e-paper waveform table refresh lasts approximately 20–30 milliseconds, and a complete full refresh may comprise dozens of frames.
The state-retention characteristic of e-paper displays originates from bistability, whereby the image is retained after the screen is powered off.
E-paper consumes zero power during static display, with a theoretical standby time of months or even years.
A full refresh of e-paper takes 1–3 seconds, while the red/yellow refresh of three-color panels takes 10–15 seconds.
E-paper displays have a bistable property whereby the image is retained on the screen even when power is completely cut and does not disappear.

50%UnverifiedA full refresh of an e-paper display goes through a black-and-white flashing process that thoroughly eliminates ghosting, fast refresh is quicker but may leave slight ghosting, and partial refresh is the most responsive but results in the most pronounced ghost accumulation.
