Apple is expected to bring its True Tone display to more products this year. According to investment bank Barclays, and reported by MacRumors, Apple will include the new display technology in the next crop of iPhones.

The True Tone display was first announced alongside the 9.7-inch iPad Pro last year, but it never made its way into other devices, including the bigger 12.9-inch iPad Pro or iPhone 7. The report states the True Tone display will be available in three models: iPhone 7s, iPhone 7s Plus and iPhone 8. The naming scheme for the next iPhones hasn’t been confirmed, so this detail is subject to change.

The display feature isn’t high profile, but it was always expected Apple would add the feature to more products and use it as a selling point.

What exactly does the True Tone display do?

The main function of the True Tone display is to adapt the display according to the ambiance of a room. Here’s Apple’s official description of the feature:

[The feature] uses advanced four-channel ambient light sensors to automatically adapt the color and intensity of the display to match the light in your environment. Which means reading is more natural and comfortable — almost like looking at a sheet of paper.

In our testing of the 9.7-inch iPad Pro, the True Tone display really does make a difference. The True Tone display feature is different from Apple’s Night Shift, which makes a device’s display warmer.
