Samsung to Try to Beat Apple to Market with a "Retina" Display Tablet
BGR reports that Samsung is preparing to launch its own high resolution tablet that will carry a 2560 x 1600 resolution screen that would beat the 2048x1536 display that the iPad 3 has been rumored to have.
Even though the tablet features a larger display than Samsung’s Galaxy Tab 10.1, we’re told that the tablet is “barely larger” due to the fact the slate will have a thinner bezel with a whopping 2560 x 1600 resolution, 11.6-inch screen with a 16:10 aspect ratio.
Samsung introduced a similar 2560x1600 screen that uses the less conventional PenTile technology to achieve its high resolution back in May at SID Display Week 2011 International Symposium.
The PenTile display uses a series of local filter operations to convert the underlying image into display intensities, including convolution, thresholding, color curve adjustment, and postprocessing with locally-adaptive filters. In practice, this means the display blurs the red and blue channels by dispersing these color intensities to the nearest subpixel element of the right color, and then also implements subpixel positioning to increase the apparent resolution again. However, subpixel spacing is not constant across the display, making the real apparent resolution complicated to estimate.
Rumors that Apple has been working on the high resolution display have been circulating about a year. Apple's iPad 3 is expected to carry a resolution of 2048x1536 both vertical and horizontal ones. Rumors have suggested that there have been production constrains on creating these high resolution screens in quantities that are enough to satisfy Apple’s needs.
