There will be a larger successor to the iPhone X in 2018.
Apple apparently sent out an order to Samsung Display, the iPhone X's OLED display manufacturer, for 5.28, 5.85, and 6.46-inch OLED displays, but the order for the smaller 5.28-inch display has been cancelled, according to ET News.
The rumor suggests that Apple may be adding a larger 6.46-inch iPhone X successor to its lineup next year. The iPhone X, coming in November, will have a 5.8-inch OLED display.
If the 2018 iPhones do have near bezel-less displays, that could mean the end of the iPhone 6-era hardware designs.
This is purely our own speculation based on the rumor that Apple will use Full Active LCD displays, one of which is reported to be larger than the current 5.5-inch iPhone 8 Plus display.
The 2018 iPhone will likely look different, if not totally redesigned, if Apple uses Full Active LCDs for the iPhones, and use near bezel-less front panels. For one, the 2018 iPhones wouldn't have bezels as large as they are on the iPhone 8, and the iPhone 8's design is essentially the same as the 2014 iPhone 6, with similar bezels around the display.
One of the 2018 iPhones will have a large screen measuring over 6 inches.
Apple has made orders for an LCD display panel that's over six inches large, according to The Korea Herald. The order was made to Japan Display, which is the same company that's supposedly providing the aforementioned Full Active LCDs for Apple's iPhone 8 successors.
Since the display order is apparently for LCD panels, it doesn't seem likely that the order is designed for a successor to Apple's new iPhone X, which has an OLED panel. Instead, it seems more likely that the large LCD panels will be destined for the successor to the iPhone 8 Plus.
The successors to the iPhone 8 will have near bezel-less front panels.
Apple's next "mid-range" iPhones could have a similar bezel-less front as the iPhone X in 2018, according toThe Wall Street Journal.
Specifically, Apple is supposedly looking into an advanced type of LCD display called "Full Active LCD," made by Japan Display. You can actually get an idea of what Full Active LCDs look like by checking out the Essential Phone (below) and the Xiaomi Mix 2. One thing to note about phones that use Full Active LCDs is that, unlike phones with OLED displays like the iPhone X, they all have at least one larger bezel, usually on the bottom.
This type of LCD display would be less expensive and would most likely run into fewer supply issues than the OLED display used in the iPhone X, two factors that surely contribute to the iPhone X's higher cost. The iPhone 8 starts at $699, the iPhone 8 Plus starts at $799, and the iPhone X starts at $999.
