The U.S. Patent and Trademark Office has granted Apple a patent for displays with multiple refresh rate modes. It was spotted by Patently Apple.
Apple notes that displays may be operable at a native refresh rate that is equal to the highest refresh rate at which the display has full resolution. When operating at the native refresh rate, each row of pixels may be scanned sequentially. Displays may also be operable in a high refresh rate mode with a high refresh rate. In the high refresh rate mode, the display may operate at a refresh rate that is twice the native refresh rate, three times the native refresh rate, or four times the native refresh rate (as examples). The native refresh rate may be 120 Hz and the high refresh rate may be 240 Hz, as one example. The native refresh rate may be 60 Hz and the high refresh rate may be 120 Hz, 180 Hz, or 240 Hz, as another example.
