The Measurements section below has details of all of the lab measurements and tests with lots of additional background information and explanations including the display's
Maximum Brightness and Peak Luminance, Black Brightness, Contrast Ratio, Screen Reflectance, Bright Ambient Light Contrast Rating, Dynamic
Color and Contrast,
Color Temperature and White Chromaticity,
Color Gamut,
Intensity Scale and Gamma, the variation of Brightness, Contrast Ratio and
Color Shift with Viewing Angle, Backlight Power Consumption, and Light Spectrum of the display.
Among all existing Tablets of any size, the iPad mini 4 takes first place and breaks performance records in many of the most important test categories including: lowest screen Reflectance (2.0 percent), highest contrast rating in high ambient light (225), a near perfect log - straight
intensity scale and gamma of 2.22, and the highest absolute
color accuracy (average /
maximum color errors of 1.9 and 4.2 JNCD — tied for first place with the Microsoft Surface Pro 4).
