Rev.1.2 RVT28AEFNWR00 Note 1. Contrast Ratio(CR) is defined mathematically as below, for more information see Figure 1 Contrast Ratio = Average Surface Luminance with all white pixels (P1, P2, P3, P4, P5) Average Surface Luminance with all black pixels (P1, P2, P3, P4, P5) Note 2. Surface luminance is the LCD surface from the surface with all pixels displaying white. For more information see Figure 2. Lv = Average Surface Luminance with all white pixels (P1, P2, P3, P4, P5) Note 3.
