Apple expected to unveil iphone with 6.5-inch screen

Apple is expected to unveil its biggest and most expensive iphone on Wednesday 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.

If the speculation pans out, the even-bigger iphone would represent Apple’s attempt to feed consumers’ appetite for bigger screens as they rely on smartphones to watch and record video, as well as take photos wherever they are.

The iphone X, a dramatically redesigned model released last fall, was the first mass-market smartphone to demand a $1,000 starting price.
