Ipad how does auto brightness work

Inverting colors is often useful for people who have visual impairments or simply want to reduce eyestrain. Although, to most users, the screen may look a little too strange for everyday usage, others will certainly find this feature very useful.

All you need to do to invert colors on an iOS device is follow the same steps as listed above and toggle on the switch to invert colors. This will immediately change the appearance of the screen. Many smartphones come with an auto-brightness feature that aims to both conserve battery power and make the screen easier to see when you are using it. The iPhone's auto-brightness feature has been on every model since the smartphone was introduced by Apple in Although at least one study has questioned the effectiveness of the auto-brightness feature, it can still help to reduce eye strain and conserve battery power if enabled.

The glass touch-screen LCD display of the iPhone measures 3. It has a resolution of by pixels at ppi pixels per inch. Turn on your iPhone and tap "Settings" on your Home screen. Tap "Brightness" to open the display brightness settings. Slide the "Auto-Brightness" slider until "On" appears. Press the "Home" button to return to the Home Screen.

This is also convenient -- if your iPad can adjust itself, then you don't have to do it. If you turn off the default, you have to make manual adjustments whenever your ambient lighting changes enough to make your screen unreadable.

It can also reduce eye strain and glare, which is useful if you use your iPad for long periods of time. The brightness settings on an iPad may not suit every user all of the time. Some people find that the screen is too bright or too dim in certain lights and may find that glare strains their eyes or that the screen is not as easily readable as it should be.

Some users have reported problems getting the setting to work at all, even though it is turned on by default. If your Auto Brightness setting is working but you aren't comfortable with the set level, you can easily change the setting manually to suit your eyes. It is located in the Settings menu -- if you tap "Brightness and Wallpaper," you can toggle Auto Brightness on and off or use the slider to adjust levels.
