Samsung Debuts Thin New Tablets With Killer Screens

Samsung's claim that the Galaxy Tab S line has the most advanced display technology is true, said IHS iSuppli's Sweta Dash. Its 8.4-inch tablet offers 359 ppi, compared to the Kindle Fire HDX's 339 ppi. The 10.5-inch Galaxy Tab S offers 288 ppi compared to the iPad Air's 264 ppi. OLED tech enables thinner devices than LCD and a better contrast ratio. However, it costs more to produce, too.
