Samsung working on ultra high resolution displays for selected future tablets7
To give you an idea how much 400 pixels per inch is, we have to mention that the Samsung Galaxy Tab has an LCD standing at only 170 DPI, while the screens on both generations of the iPad sport the modest 132 DPI. The iPhone 4, in comparison, has a pixel density of 326 dots per inch, which is what makes its screen look so sharp and beautiful. Samsung promises that its next generation high resolution displays will not have a negative effect on battery life as they will most probably consume just as much power as their present-day counterparts. It was also mentioned that a glasses-free 3D display may also find its way to a future Samsung tablet as long as market demand for such technology grows high enough.
Of course, it will probably take at least a year until Samsung's ultra high resolution displays finally make an appearance on a tablet since nowadays the technology behind them is still anything but cost-efficient. Who knows, maybe another company is planning on beating Samsung to it?
