Without going into technical details, Samsung posted an infographic that shows why Super AMOLED screens are superior to LCD ones. Among the listed reasons you’ll find a higher contrast ratio, wider viewing angles, and more accurate colors.
With Super AMOLED screens that feature 1600 x 2560 pixel resolutions, the Galaxy Tab S 10.5 and Tab S 8.4 certainly have a place among this year’s best tablets. Of course, they offer many other attractive features besides nice displays, including Exynos 5 Octa processors, 3 GB of RAM, expandable internal memory, 8 MP rear cameras, and Android 4.4 KitKat. You can read our Galaxy Tab S 10.5 review here, and our Galaxy Tab S 8.4 review here.
The 8.4-inch Galaxy Tab S can currently be bought for $399, while the 10.5-inch model costs a bit more: $499. Both are widely available around the world, and could become Samsung's best-selling high-end slates yet.
