Samsung outguns Apple in Tablet display shoot out
Not quite sure how much to make of this, but it makes interesting reading… Dr. Raymond Soneira of DisplayMate Technologies has run a Display Technology Shoot-Out series, featured on the website Gizmodo.
He provides side-by-side comparisons – based on “detailed lab measurements and extensive viewing tests” of five major new tablets: Apple iPad 2, the Motorola Xoom, the Asus Transformer, the Acer Iconia, and the Samsung Galaxy Tab 10.1.
The headline grabbing material comes in the conclusion, where Soneira writes:
As things stand, based on all of the display tests, the iPad 2 and Galaxy Tab 10.1 are reasonably close in performance in most categories, so it’s almost a tie, but the Galaxy Tab is ahead more often than the iPad 2, so the Galaxy Tab is the Winner, by a nose.
But there is lots of interesting material before the garlands are awarded. For example, one section of their report covers ‘Screen Myths‘:
Most people (and reviewers) seem to believe that the 10.1 inch screens (measured diagonally) on the Android Tablets are larger than the 9.7 inch iPad screen – but they are actually 5 percent smaller than the iPad in terms of the image area of the screen, which is what really counts. This is due to both Aspect Ratio geometry (the screen area decreases as the Aspect Ratio increases) and the Android system bar, which reduces the image area.
The shape of the screens are also significantly different: the iPad has an Aspect Ratio of 4:3 = 1.33 (the ratio of width to height) and the Android Tablets all have an Aspect Ratio of 16:10 = 1.60. But because of the Android system bar the Aspect Ratio of the image area is larger, 1.70, which is rather close to the HDTV 16:9 Aspect Ratio of 1.78. So Android Tablets are very well suited for watching widescreen video in Landscape mode. However, they are generally considered too narrow to be very useful in Portrait mode. On the other hand, the iPad does not have a widescreen, but instead an Aspect Ratio very close to standard 8.5 x 11 inch paper, so it is naturally very good for reading lots of content in Portrait mode. In many cases it is also better for reading content in Landscape mode because the iPad’s image height is 5.8 inches while the Android Tablets have an image height of only 5.0 inches, so you can see more on the iPad before needing to scroll. On the other hand, for watching 16:9 widescreen videos, the iPad image height is only 4.4 inches, which is smaller than the Android height of 4.8 inches for 16:9 widescreen videos. So the best screen shape depends on your intended mix of applications.
One strongly positive point is Soneira noting that there was not a single bad pixel on any of the tested units….
