ABSTRACT:
A graphics controller can operate in a working state and a low power-consumption state. The graphics controller includes a register and a logic unit. The register is used to control the operating state of the logic unit. The graphics controller further includes a state controller configured to invalidate the state control data stored in the register and designating the low power-consumption state, thereby to maintain the logic unit in the working state.
