Samsung is looking to come up with a rival for Retina Display?
Samsung is ready to beat Apple at another topic, one that has been almost denied to all Android fans until the moment: the pixel density of the display. It seems that the Korean company has managed to obtain a far more superior PPI coefficient (pixel per inch) in their latest lab session, one that tops Apple’s Retina Display by using a rather-new technology for development.
Since Apple came up with a catchy nickname for their superior pixel resolution, Retina Display has been hunted by other manufacturers but without success, at least for now. Fortunately, Samsung has made an important step in that direction, by producing a prototype AMOLED screen that uses Fine Metal Mask technology, known as FMM, instead of laser-induced thermal imaging (LITI).
Basically, Samsung will actually renounce at using laser-induced thermal imaging, a technology focused by the Korean department of research and development since ages and adopted instead of FMM in 2011. Almost one year later, Samsung gets back to its call and considering the latest advances in Fine Metal Mask technology, the company now poses the means to produce touch-screen panels of greater quality.
In a few words, the Fine Metal Mask technology is used to deposit pixels on a substrate, by placing a metal mask with small grooves and then spraying the composition with an organic substance.
Although an AMOLED display offers great colors, they fall short in terms of resolution. Using FMM principles, Samsung is going to resolve the issues and as the prototype panel shows, future smartphones will be packing panels with 350 PPI or even more. As a comparison, the latest Galaxy model has a 306 pixel density, while the iPhone 4S comes with 326, rendering the visual difference between the two models noticeable.
According to industry sources, Samsung achieved the performance only in lab tests and the actual consumer result may vary. But if we were to speak of options, the Korean company may actually release these new-age panels in future creations as the next Galaxy S phone or even the third-generation Tab, with pixel densities closely orbiting around the 350 mark and out-of-the space resolutions.
Another possible option would be the Galaxy Note 2, which is supposed to have a 5.5-inch wide display and a 1650 by 1050 pixel resolution. If you do the math, this gives you a density of almost 355 PPI, strangely close to the latest lab results.[Via] ETNews
