10. Screen Brightness, Contrast And Uniformity

Here are our measures of screen brightness, contrast and uniformity of brightness.

Screen Brightness, Contrast And Uniformity Conclusions

With maximum brightness scores of 94 and 99 candelas per square meter respectively the Fujitsu Lifebook B6110D and the Toshiba Portege R200 have more than enough brightness for use indoors and outdoors in deep shade. The difference in the contrast ratios of the two laptops is attributable to the Fujitsu's darker blacks. Darker blacks result in lower candelas per square meter readings for black and thus lower denominators when the Fujitsu's contrast ratio is computed.

Based on both standard deviation scores for 64 brightness measures taken across their displays and plots of these brightness measures, Toshiba's Portege R200 exhibits the best spatial uniformity of brightness we have measured in our tests so far. The Fujitsu comes in closer to our reference Acer notebook computer. It is quite easy to see these differences in the spatial uniformity of brightness graphs in the previous section.
