Samsungs new tablet tech could lead to the development of large foldable tablets with super high resolutions…..

Samsung has unveiled two new display technologies that could spur on the advancement of tablet PC technology.

Samsung Hi-Res PenTile RGBW 10 Inch Display.

Firstly, the company has revealed its new 10.1-inch tablet display that packs a whopping 2560 x 1600 resolution, with a pixel density of 300dpi. The super hi-res is supposed to rival; if not better Apple’s famed retina display.

The ultra-high resolution display uses PenTile RGBW technology, the same technology featured in the Nexus One. But many users reported frequent blurry text and occasional color banding on the Android handset; the new super hi-res tablet screen claims to have tackled these problems.

Dr. Sungtae Shin, Senior VP of Samsung Electronics explained that the PenTile display technology is not just visually pleasing, it’s also efficient; it’s the only commercial display that ‘operates at 40 percent less power yet provides twice that of Full HD-viewing performance for consumers compared to legacy RGB stripe LCDs.’

It’s not known exactly when, or in what product the new display will feature, however Samsung says it should be ready later this year, and it would seem reasonable to think that it will feature in the company’s Galaxy Tablet line.

Samsung Flexible AMOLED Display

The company has also unveiled its prototype flexible active matrix organic-light-emitting-diode (AMOLED) display, which could make its way in device such as wrist watches, handheld gaming consoles, notebooks and tablets. The breakthrough with this technology has little to do with hi-resolutions, and more to do with the ability to be folded without damaging the displaying.

Previous flexible AMOLEDs could be flexed and rolled, but 180 degree folds resulted in visible creases on the screen. Samsung’s new technology allows the display to be completely folded in half, and reopened without leaving a crease.

By using a combination of AMOLED panels, silicone rubber (a hyperelastic material), a protective glass cover, and a module case, the company has crafted a design that can be flexed with a folding radius of just 1mm, allowing the screen to sit directly on top of one another.

The Gadgetian speculates that we could see the ‘world’s highest resolution Flexible AMOLED. with a resolution of 480 by 800, a bending radius of <10mm, weighing 2.1 g, thickness of 0.27mm and a brightness of 300 cd/m² early next year.’ Unfortunately the two technologies are being developed separately, however since AMOLED screens can be used as touch screens, it’s likely that we will eventually see flexible AMOLED screens with such high resolutions. This could lead to development of large, hi-res tablet PCs that could be folded up and pocketed to save space on the go.
