Basic Display Metrology

For display devices to present information clearly and accurately, its performance and quality are of utmost importance. The display must be capable of presenting information that is readable under different visual conditions. If the display is intended to be used in a dark or low-level lighting environment, it must emit enough light to reduce adaptation strain and discomfort glare while maintaining legibility. If they are to be used under bright ambient light environment, the display must have enough contrast to be readable.

In display metrology, CIE 1931 Yxy Chromaticity Diagram and CIE 1976 Yu’v’ Color Space are commonly used to describe colors in numbers. Some of the common display performance parameters includes white balance, color gamut, gamma, contrast ratio, uniformity, and flicker.

Konica Minolta sensing instruments and solutions are widely used to characterize display. Spectroradiometers, Color Analyzers, and Luminance Color Meters help ensure display performance and quality standards are met with ease.
