  • Page 48 Notes : 1. Contrast ratio(CR) is defined mathematically as :It is measured at center point(1) Surface luminance with all white pixels Contrast ratio = --------------------------------------------------------- Surface luminance with all black pixels 2. Surface luminance is the luminance value at center 1 point(1) across the LCD surface 50cm from the surface with all pixels displaying white.
