Display contrast

Physics Concepts and Laws

In physics and digital imaging, contrast is a quantifiable property describing differences in appearance within a visual field. It is linked to perceived brightness and may be defined using luminance-based formulas, including Weber contrast and a high-luminance ratio. Contrast can also result from chromaticity differences. In electronic displays, it is affected by the signal driving mechanism, ambient illumination and the viewer's direction of observation.

Definition: A quantifiable property describing differences in appearance between elements in a visual field.
Luminance measures: It can be quantified as ΔL/L near the luminance threshold or as LH/LL at higher luminances.
Display influences: Ambient illumination and viewing direction affect perceived contrast.
