True Tone is an important function of the leading competitors of iPhone and iPad. It uses a multi-channel ambient light sensor to intelligently adjust the color of the screen display to achieve a more comfortable eye.
True Tone was first applied to the 9.7-inch iPad, and now the technology of the iPhone and MacBook screens has been launched.
A new patent published by the US Patent and Trademark Office on Tuesday showed that True Tone was extended to the keyboard of the MacBook Pro to intelligently adjust the brightness of the keyboard.
Apple describes how to finely control the white brightness of keyboard letters/symbols, including adjusting the color temperature, making the keyboard more attractive to users, or more comfortable to use.
In other words, Apple not only wants users to turn on the keyboard backlight in dark light to solve the problems that can be seen and seen, but also to enjoy the eyes.
In addition, Apple does not directly rely on the True Tone sensor that supports the screen, it may be that they have different judgment mechanisms for color and color temperature.
