Samsung has introduced two devices featuring high-res SuperAMOLED displays with 2,560 x 1,600 resolution. The 10.4in Galaxy Tab S and the 8.4in 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 1Q14 to try and reach or surpass Apple's control on the market with 33 per cent share during the same period. Apple's share slid from 40 per cent in the previous quarter.

The Samsung tablets compare favourably to Apples iPad Air and iPad Mini specifications in terms of weight, screen size, pixel density and slimness, the company stated.

The Galaxy Tab S boasts a display that claims to rival iPad's 'retina' display. Samsung said the company's screen technology offers better colour and deeper contrast while consuming less power than the LCDs 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 Apples latest iPads.

The Tab S devices have a slightly higher pixel density than existing iPads. Samsung's 10.5in model offers 287ppi as compared to the iPad Airs 264ppi and the 8.4in Tab S has a 359ppi screen that compares to the iPad Minis 326ppi display.

Both Samsung tablets are available in a 16GB capacity and for now, the Tab S will be WiFi-only. The 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 10.5in model has a 7,900mAh battery on board while the 8.4in 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 SVP at Samsung Electronics America.
