Samsung Display is said to be developing new pixel layouts for its well-known Super AMOLED smartphone display panels, according to sources close to the situation. Produced by a Laser-induced thermal imaging process (LITI), the new hexagon and diamond-shaped layouts, as opposed to the current side-by-side squared layout, would increase the pixel density in Samsung’s upcoming 5-inch mobile display to well above the 440ppi mark. That would actually cross the impressive boundary set by recently announced Android smartphones with 5″ 1080p screens, like the Sony Xperia Z / ZL, HTC Droid DNA / Butterfly, Huawei Ascend D2, ZTE Grand S, LG Optimus G Pro, Panasonic ELUGA X P-02E, Oppo Find 5 and Fujitsu ARROWS X F-02E.
The source also claims the Galaxy S IV will be the first to debut with such a display, which conflicts with earlier rumors that the handset would feature a 4.99-inch 1080p FHD Super AMOLED display with standard 440ppi. The next-generation Galaxy S device is rumored to be announced on March 22 and released in April, so we may have to wait a couple months before hearing anything official.
Preliminary Galaxy S IV specs: Exynos 5 Octa 1.8GHz 8-core processor, 4.99-inch 1080p full HD Super AMOLED display, 13 megapixel rear camera, 2MP front-facing camera, 2GB of RAM, 4G LTE connectivity, a micro SD slot, 2600mAh battery, wireless charging functionality, and Android 4.2.1 Jelly Bean.
