SAN FRANCISCO —Apple is expected to unveil its biggest and most expensive iPhone on Sept. 12, as part of a lineup of three new models aimed at widening the product’s appeal amid slowing sales growth.
Most of the buzz is swirling around a rumored iPhone that is supposed to boast a 6.5-inch OLED screen, up from 5.8 inches on the existing iPhone X. OLED is a step up from traditional LCD technology in offering a display without a backlight, so black is truly black rather than simply dark.
