heijastinnäytävät

Heijastinnäytöt, known in English as reflective displays or e-paper displays, are a type of electronic visual display that mimics the appearance of ordinary ink on paper. Unlike backlit displays such as LCD or OLED, heijastinnäytöt do not emit light themselves. Instead, they rely on ambient light to reflect off the display surface, making them highly readable in bright sunlight and consuming very little power.

The technology behind heijastinnäytöt typically involves microcapsules containing charged particles of different colors, often black and white. When an electric field is applied, these particles move to the surface of the microcapsule, forming an image. This process is bistable, meaning the display retains its image even when power is removed, further contributing to its low energy consumption. This makes them ideal for applications where power efficiency is paramount, such as e-readers, digital signage, and price tags.

While heijastinnäytöt excel in readability and power saving, they generally have slower refresh rates compared to emissive displays. This can result in a less fluid viewing experience for rapidly changing content like videos or fast-paced games. However, advancements in technology are continuously improving their performance, making them increasingly versatile for a wider range of applications. Their eye-friendly nature and resemblance to physical paper are significant advantages in many use cases.
