A little over a week ago it was suggested that Samsung could be introducing a 4.99” Full HD display on its upcoming Galaxy S4, giving it a pixel density of 440 PPI. There is no doubt that this density is incredibly sharp but at the same time, apart from its AMOLED display, there’s not much else separating it from the likes of HTC and Sony who both have 5” phones with similar pixel densities. That being said, a report from Digitimes has suggested that Samsung is currently exploring a new pixel layout for their AMOLED displays which could result in higher pixel densities and could also be making an appearance in the upcoming Galaxy S4 (and future Galaxy devices). The report has indicated that the South Korean company is looking at different layouts and are experimenting with hexagonal and diamond shaped pixels which will allow Samsung to achieve pixel densities greater than 440 PPI.
This is possible thanks to the use of Laser-induced Thermal Imaging which is said to be not only cheaper but allows for smaller subpixels. However it would seem that this technique could not be used earlier as R&D had problems scaling the process for mass production, but apparently the issues have already been resolved and that production could be underway or is set to begin. If anything this would be a great way to trump the competition in addition to the possibility that the Galaxy S4 could also be utilizing the newly announced Samsung 8-core Exynos 5 chipset. We wouldn’t get our hopes up too high just yet, but with the Galaxy S4 supposedly launching in the next few months, we expect more rumors and leaks to make their way onto the internet.
