The Samsung Galaxy Tab S is the new market leader when it comes to screen technology, according to research company DisplayMate Technologies. The Korean company's latest slate pushes the Amazon Kindle Fire HDX and Apple iPad Air into second and third place, respectively. The Tab S, which comes in 10.5- and 8.4-inch versions, is the "best performing tablet display that we have ever tested," wrote Raymond Soneira, president of DisplayMate, in a review posted Tuesday. Areas that the Tab S displays are rated tops include highest color accuracy, lowest screen reflectance, and smallest brightness variation with viewing angle. The gadget starts at $500 in the US and £450 in the UK, with Australian prices yet to be announced. The technical review underscores the ascendency of OLED over LCD technology.
