Samsung S tablets boast display rivaling Retina

The battle for ascendancy in the thriving tablet market between Samsung and Apple heats up as the South Korean giant revealed two devices that feature SuperAMOLED displays boasting 2,560px by 1,600px resolution.

The 10.4-inch Galaxy Tab S and the 8.4-inch Galaxy Tab S will comprise the company's flagship 'S' series of tablets and will aim to boost Samsung's global tablet market share from 22 per cent in the first quarter of 2014 to try and reach or surpass Apple's stranglehold on the market which saw the U.S. giant attain 33 per cent share during the same period. Apple's share slid from 40 per cent in the previous quarter.

The new Samsung tablets compare favourably to Apple's iPad Air and iPad Mini specifications in terms of weight, screen size, pixel density, and slimness.

The Galaxy Tab S boasts a high-res SuperAMOLED display with 2,560px by 1,600px resolution to rival iPad's Retina display. Samsung claims the company's screen technology provides better colour and deeper contrast while consuming less power than the LCD displays in most tablets. Samsung had kept its SuperAMOLED display technology only for the company's smartphones.

Both wafer-thin tablets measure 6.6mm as compared to the 7.5mm set by Apple's latest iPads.

The 10.5-inch and the 8.4-inch Tab S have a slightly higher pixel density than existing iPads. The model with the bigger display offers 287ppi as compared to the iPad Air's 264ppi, while the other Tab S model has a 359ppi screen which compares to the iPad Mini's 326ppi display.

Both Samsung tablets are available in a 16GB capacity and for now, the Tab S will be Wi-Fi-only.

Both Samsung tablets are equipped with Android 4.4 KitKat running on a Samsung Exynos 5 Octa CPU with 3GB RAM. The eight-core CPU can jump back and forth between a 1.9GHz quad-core processor and a 1.3GHz quad-core processor depending on the task. The 10.5-inch model has a 7,900mAh battery on board while the 8.4-inch model features a 4,900mAh battery.

To optimise the viewing experience, Samsung has also equipped the Tab S with an adaptive display, which will change the white balance of the tablet based on the ambient light. The screen claims to have less reflectivity in bright sunlight.

Samsung's Adaptive Display technology changes the screen's saturation and brightness while certain apps are being used, and an RGB sensor detects ambient light to adjust white balance on the fly. The Tab S also claims to be capable of supporting 11 hours of 1080p video playback.

Samsung also claims to have pumped up the picture quality by bringing a wider colour range to the screen than the company's preceding devices. HD quality has also been announced to address the burgeoning Netflix and YouTube generation.

"It portrays the true colours that content creators intended," Michael Abary, a senior vice president at Samsung Electronics America.
