einkskärmar

Einkskärmar, often referred to as e-ink displays or electronic paper, are a type of display technology designed to mimic the appearance of ordinary ink on paper. Unlike traditional LCD or OLED screens that emit light, e-ink displays reflect ambient light, making them highly readable in direct sunlight and significantly reducing eye strain during prolonged viewing. This reflective nature also contributes to their extremely low power consumption, as the display only requires power when changing the image, not to maintain it.

The core technology behind e-ink involves microcapsules containing positively charged white particles and negatively charged black particles suspended in a fluid. When an electric field is applied, either the white or black particles are moved to the surface of the microcapsule, creating the desired image. This bistable nature means the image remains visible even after the power is removed.

E-ink technology is most commonly found in e-readers like Amazon Kindle and Kobo devices, where its paper-like quality enhances the reading experience. It is also used in digital signage, smart cards, and some electronic shelf labels due to its low power needs and excellent readability. While e-ink offers advantages in readability and power efficiency, it typically has slower refresh rates and a more limited color palette compared to other display technologies, making it less suitable for applications requiring fast motion or vibrant, dynamic color.
