According to the patent details, when the liquid produces false input on the screen, it will be detected and filtered by the system. In other words, the system will detect screen misoperation caused by liquid, and then automatically filter out these misoperation.
The capacitive touch screen of iPhone can automatically change to pressure-sensitive input mode, similar to ForceTouch and 3DTouch technology, which can detect whether there is water on the screen. When the moisture on the screen exceeds the predetermined threshold, the system will automatically adjust it so that the finger pressing force at this time is greater than the dynamic threshold.
In addition, the iPhone also has an intimate design-when users use it underwater, the App chart in the UI interface of the mobile phone will become larger, making it easier for users to press it.
