( CNN ) -- Apple is testing iPhone display screens as large as 6 inches , according to a new report . The screens , ranging upward from 4.8 inches , would be a pretty massive leap from the 4-inch display on the iPhone 5 . But do n't expect to see them when Apple rolls out new iPhones next week . Citing `` people familiar with the matter , '' the Wall Street Journal on Friday reported that the bigger screens could signal a future move by Apple to offer iPhones of various sizes . That would put them more in line with their chief rival , Samsung , which has put a dent in the iPhone 's dominance with devices like their Galaxy S and Galaxy Note lines . On Wednesday , Samsung unveiled its Galaxy Note 3 , with a whopping 5.7-inch display that further blurs the boundary between large phone and small tablet . On Tuesday , Apple is expected to roll out two different iPhones -- an update to the iPhone 5 and a cheaper model that would be designed to appeal to buyers in emerging markets like China and India . Apple CEO Tim Cook has knocked Apple 's rivals for making `` trade-offs '' in order to pack larger screens into phones , although he has not ruled out such a move for future iPhones . Opinions are split on whether Apple will also introduce other products , like a new iPad or a much-anticipated smartwatch , next week . The Journal report said the iPhones unveiled next Tuesday will likely have the same size screen as the current model . An Apple spokesperson , predictably , declined to comment .
