According to media reports, if the future iPhone 5S touch screen maintains the original dimensions, then the exponentially growing touch screen pixels means that the resolution will be greatly improved. At present, the Apple iPhone 5 screen number is 727,000 pixels, if the pixels number of iPhone 5S reaches to 1.5 million, then only the 1704*960 pixel resolution can maintain the original aspect ratio, and provides backwards compatibility to the current applications.
However, seen from the current various reports, it seems that only little mentioned iPhone 5S will be doubled upgrade in the touch screen resolution, so even if this argument may become a reality, but it perhaps might appear in the future iPhone 6.
According to other media, Apple is considering to launch a larger size touch screen tablet product than the current 9.7 inches iPad. And the screen size is allegedly to reach 12.9 inches, and it’s tentatively called as iPad maxi, and it’s expected to be released in the first half of next year.
Of course, the authenticity of the two news still needs to be confirmed, but touch screen upgrade including the iPhone and iPad should be the trend, it’s believed that in the near future we should be able to see the larger screen and higher resolution Apple iPhone and iPad.
