Finally: ‘The screen of the next iPhone always stays on’ – News

The next new iPhone will have a screen that stays on forever. That is what the usually well-informed tech blogger Max Weinbach claims. The technology would be similar to that of the Apple Watch Series 5, which also has a screen that does not go black.

The advantage of a screen that remains active is that the user can view the clock and some notifications at all times. Incidentally, the technology is far from new: the so-called always-on display already debuted on the Nokia N86 from 2009 and in the following years also found its way to – especially – the top devices from Samsung, LG, Huawei and Motorola. In Android land, these kinds of screens have become commonplace, but iPhone displays remained completely black until you unlocked the device.

OLED blood

To support always-on, a smartphone must have an OLED screen. They are more expensive than traditional LCDs, but have the advantage that each pixel can be controlled separately. As a result, most of the screen can remain off, while a few pixels are activated to show, for example, the time and battery status. That hardly costs battery capacity. This is not possible with an LCD screen, because the backlight immediately switches on for the entire display.

The 2017 iPhone X was Apple’s first smartphone with an OLED screen. Since last year’s iPhone 12 series, the cheaper models also use OLED. It is unknown whether the always-on function will also come to older iPhones via a software update.
