13. The Lifebook P1510D's Display: A Study In Virtuosity, Continued

Unfortunately, the P1510D's blacks are not as black as those of the other computers we tested, leaving it with a contrast ratio score of only 71. However, the P1510D still delivers a sharp, bright picture with enough contrast for most viewing environments.

Based on both its adjusted standard deviation score for 64 brightness measures taken across its display (87) and the plot of these measures shown above, the Lifebook P1510D exhibits decent though not spectacular spatial uniformity of brightness. In a dark room, with the display set to pure white (Red=255, Blue=255, Green=255), the distribution of brightness can be seen as patches of darker and lighter areas on the screen. In practical use the P1510D's spatial uniformity of brightness had little impact on the quality of screen images.

The P1510D's spatial uniformity of display contrast ratios, shown in the chart above, is OK, but not great. As with spatial uniformity of brightness differences in contrast ratio distribution tend not to visibly degrade image quality in real world use.
