Printed E-Paper Displays

The Lowest Power Displays In The World?

Printed e-paper displays utilize electrochromic reflective technology, offering excellent visibility with very low angle dependency. These displays are ultra-low power, characterized by semi-bistability. This means that power is primarily consumed during display transitions, with only occasional refresh pulses required, typically occurring once every 2 minutes.

What is a Printed E-Paper Display?

A printed e-paper display, also known as a printed electronic paper display or simply e-paper display, is a type of electronic display technology that mimics the appearance of ink on paper. It utilizes electronic ink (e-ink) or similar materials to create text and images that are highly readable and can be updated electronically.

Key Features

  • Low Power Consumption: E-paper displays consume power only when the image changes. Once an image is displayed, it can be maintained without any power consumption, unlike traditional LCD or LED displays that require continuous power.

  • High Contrast and Readability: E-paper displays mimic the appearance of ink on paper, providing high contrast and readability even in bright sunlight. This makes them ideal for e-readers and outdoor signage.

  • Flexible and Lightweight: Printed e-paper displays can be made on flexible substrates, allowing them to be lightweight and potentially foldable or conformable. This flexibility opens up possibilities for new form factors and applications.

  • Wide Viewing Angle: E-paper displays typically offer a wide viewing angle, similar to paper. This means the content remains visible and readable from various angles without distortion.

  • Bi-Stable Technology: E-paper displays are based on bi-stable technology, meaning they retain the displayed image without continuous power. This makes them energy-efficient and suitable for applications where power conservation is crucial.

  • Durable and Long-lasting: E-paper displays are durable and can withstand a high number of image updates over their lifetime. They are also resistant to image burn-in, a common issue with traditional display technologies.

  • Reflective Display Technology: E-paper displays use reflected light rather than emitting light like traditional displays. This reduces eye strain and makes them suitable for prolonged reading.

  • Customizable Designs: Printed e-paper displays can be easily customized in terms of size, shape, and colour. They can be integrated into various products and surfaces, enabling innovative design possibilities.

Recommended Driving Scheme

Fundamentally the displays are very straightforward to drive. A positive voltage (in reference to the counter electrode) turns ON the display segment, while a negative voltage (or shortening the work and counter electrode) turns OFF the segment. A higher voltage level enables a faster switching speed, while a lower voltage enables a longer lifetime. Typically, a good trade-off between lifetime and switch speed is to use ±1,5V across the segment. However, the displays achieve full contrast down to 1V.

If switching speed is not an issue, it is recommended to keep the voltage to a minimum. Higher voltage is optional for devices with shorter lifetime requirements. Turn OFF voltage should typically be kept the same as turn ON voltage (but with the opposite polarity) but if a longer switching time is acceptable, it is possible to shorten (≈0V) the counter electrode and the work electrode to turn the segment OFF (Driving scheme E). Below follows a few different driving schemes suggestions.
