Methods and devices employing circuitry for reducing power usage of a touch-sensitive display are provided. In one example, a method for reducing power usage of a touch-sensitive display may include receiving power for the display of an electronic device. The method may also include powering a touch subsystem and a display subsystem of the display. The method may include, in a standard display mode, receiving synchronization signals at a first rate. A frame of data is stored on pixels of the display subsystem between each synchronization signal. The method may also include, in a low power display mode, receiving synchronization signals at a second rate. The second rate is less than the first rate. The method may include detecting a touch of the display via the touch subsystem between each synchronization signal. |
