Brightness is the luminance of a display, measured in candelas per square meter (cd/m², or “nits”). It quantifies the amount of light the screen emits per unit area. Higher brightness values improve image visibility in bright environments (e.g. outdoors). Typical consumer screens range from about 200–400 cd/m², whereas industrial, medical, or outdoor displays can exceed 1000 cd/m². Very high brightness is critical for “sunlight-readable” devices, though it also increases power consumption and heat output.
