2.1-A - Contrast Ratio for Display
For displays on products, at least one mode must exist where the
contrast ratio between the luminance at light state compared to
luminance at dark state shall be 5:1.
Note: Light (or high) state typically refers to the lighter condition
for the display. For example, white content/background on an LCD. Dark
(or low) state typically refers to the darker condition for the display.
For example, black content/background on an LCD.
