screen brightness

Screen brightness refers to the level of illumination emitted by a display screen, such as those found on computers, smartphones, tablets, and televisions. It indicates how light or dark the visual content appears on the screen and is measured in nits or candelas per square meter (cd/m²). High screen brightness can enhance visibility in well-lit environments and improve the overall viewing experience, while lower brightness settings can reduce eye strain and conserve battery power in portable devices. Users can typically adjust screen brightness through device settings or physical buttons to suit their preferences and environmental conditions.
