An Always-On Display

One of the great things about an OLED display, is that each individual pixel can be turned on or off, and even emit a different level of brightness than the others. This helps create stunning contrasts and dazzling bursts of light as needed, truly bringing content to life. But another great side effect of this is battery conservation.

If you’re only using a handful of pixels, you’re using less power. Hypothetically speaking, Apple could upgrade iOS to allow OLED devices to display information, such as the clock, at all times without draining the battery too quickly.

They could do this by having text or simple graphics displayed at a low brightness in a small portion of the display. In addition to the time, iOS could display the weather, upcoming appointments, and your most important notifications without you ever having to tap your display.
