Abstract
A method for power-efficient touch input, in which touch sensor data from a touch input is obtained by touch circuitry. Touch sensor data is obtained from touch input at touch circuitry included in a device that also includes a system-on-a-chip (SOC) and a display controller stack outside of the SOC. The touch sensor data is stored in a buffer. When the SOC is in a low-power state, the touch sensor data is communicated to the display controller stack for immediate display.
