Recently, a patent document shows that in November, Apple obtained a new patent technology regarding touch screen buttons.
This technology shows that a screen can be added to the side of the phone to display content and operations. It looks like a virtual touch function screen, which can turn on the camera and display some switching buttons, somewhat similar to the traditional camera’s top operation method.
The patent description indicates that the screen can display virtual buttons, toggle buttons, and even application icons.
Although these patent applications will not immediately appear on new devices in the near future, it may one day become a reality.
