This refers to the built-in illumination feature found in certain electronic reading devices. The purpose of this feature is to provide consistent and adjustable lighting, allowing users to comfortably read digital texts in low-light or completely dark environments. For example, a user might utilize this illumination in bed at night without needing a bedside lamp.
The significance of this feature lies in its enhancement of the reading experience. It reduces eye strain by providing a uniform light source directly on the screen, minimizing the contrast between the screen and the surrounding darkness. Historically, early e-readers relied on external light sources. The integrated illumination represents a technological advancement focused on user convenience and reading comfort.
