During the presentation of the new iPhone XS on the screen behind the senior vice president of marketing for Apple Phil Schiller appeared the inscription “120 Hz touch-sensing”.
Many gasped, believing that the display of the iPhone XS has a refresh rate of 120 Hz. the image will be twice as smooth as the standard for the industry at 60 Hz.
Apple already has a device that supports 120 Hz. This is an iPad Pro 10.5. The frequency of updating the frames is really 120 Hz.
But what did the new iPhones receive? The answer to this question lies in what happened after the notorious “120 Hz”: the touch layer. That is, the screens of the iPhone XS will not be updated with this frequency – it remains at 60 Hz.
But the finger movement of the user’s sensor will process much faster: if the usual “ten” sensor read them every 16.6 milliseconds, then the new models – twice as often. Thus, the delay between touching and processing the action will take less time. But that’s just interesting, how noticeable?
