What is the refresh rate of iPhone 11?

The screen refresh rate of iPhone11 is 60Hz, but it supports 120Hz touch sampling rate. At a 120Hz touch sampling rate, the time interval for the screen to detect your finger operations is 8.3 milliseconds, while for Android phones it is 16.6 milliseconds. So in daily use, at the same 60Hz, you will feel that iPhone animations and touches are smoother than Android.

#The operating environment of this tutorial: IOS 15 system, iphone11 mobile phone.

The iPhone 11 screen refresh rate is 60Hz, not 120Hz. However, it supports 120Hz touch sampling rate. At the 120Hz touch sampling rate, the time interval for the screen to sense finger operations is 8.3 milliseconds; while for Android phones, it is 16.6 milliseconds. Therefore, in daily use, if it is also 60Hz, you will feel that iPhone animations and The touch is smoother than Android.

The most significant effect of the increase in screen refresh rate is the enhancement of picture smoothness. The lower the screen refresh rate, the image will have problems such as flickering and jitter. 60Hz is a critical point, which is just enough. . Compared with Android phones, at the same 120Hz touch sampling rate, the time interval between Android phone screens sensing finger operations is 16.6 milliseconds. This is why most people think iPhone animations and touches are smoother than Android phones. But if it is increased to 90Hz or 120Hz, the gap is still obvious.

#The iPhone 11 display can adjust the white balance to match the color temperature of the surrounding ambient light. Supports tapping or lifting to wake. The screen display supports P3 wide color gamut and original color display.
