Methods and devices employing circuitry for reducing power usage of a touch-sensitive display are provided. In one example, a method includes receiving power for a display of an electronic device. The method also includes powering a touch subsystem and a display subsystem of the display. The method includes, in a standard display mode, storing a frame of data in pixels of the display subsystem during a first period of time. The method also includes, in a low power display mode, storing a frame of data in pixels of the display subsystem during a second period of time. The second period of time is not equal to the first period of time. The method includes detecting a touch of the display via the touch subsystem between each synchronization signal of a plurality of synchronization signals received by the display. |
