When it comes to always-on display, the type of screen used on your device plays a significant role in how much power it consumes. Here are some of the most common types of screens and their impact on power usage:
- OLED: OLED screens are known for their incredible color reproduction and deep blacks, which means they’re excellent for displaying always-on content. They’re also incredibly efficient, as they only light up the pixels that need to be displayed, resulting in lower power consumption.
- LCD: LCD screens, on the other hand, are backlit, meaning that they consume a significant amount of power even when displaying always-on content. This is because the entire screen needs to be lit up, regardless of what’s being displayed.
- e-Ink: e-Ink screens are most commonly found on e-readers and are incredibly efficient, as they only consume power when the screen needs to be refreshed. However, they’re not well-suited for always-on display, as they can take a few seconds to refresh, which defeats the purpose of having always-on content.
It’s important to note that while OLED screens are the most efficient for always-on display, they’re still not perfect. Always-on content will consume more power than a blank screen, even with an OLED display. However, the difference in power consumption between an OLED display and an LCD display can be significant, so it’s worth considering when choosing a device.
Here’s a comparison table of power consumption for different types of screens displaying always-on content:
| Screen Type | Power Consumption |
|---|---|
