Abstract
A low-power display control method and associated display controller is provided. The low-power display control method detects a sensing signal to generate a sensing result. A control signal is generated according to the sensing result to control a power conversion controller to operate in a low-power power saving mode. In response to a wake-up event, the control signal is deasserted and an associated auxiliary circuit is also turned off, and then the display controller is woken up to restore to a normal operating mode.
