2. Contrast Ratio (CR) is defined mathematically as:
Surface Luminance with all white pixels
Contrast Ratio = _____________________________________
Surface Luminance with all black pixels
4. Response time
TrR measures the transition time of L1 relative luminance from white to black state, from 90% to 10% (see graph below)

TrD measures the transition time of L1 relative luminance from black to white state, from 10% to 90% (see graph below)
5. Flicker is measured at cyan dot pattern of Forground RGB (0,0,0) and Background RGB (0,31,31).
