Image processing unit, image processing apparatus and image display system

An image processing unit, comprising:

• an always on circuit block, configured to receive a first bias voltage from a power supply unit;
• and
• a non-always on circuit block, wherein when the non-always on circuit block operates under a first operation mode, the non-always on circuit block receives a second bias voltage from the power supply unit, and when the non-always on circuit block operates under a second operation mode, the non-always on circuit block stops receiving the second bias voltage from the power supply unit;
• wherein the always on circuit block outputs an operation stop signal to the non-always on circuit block according to a first event trigger signal, the non-always on circuit block outputs a power down signal to the always on circuit block according to the operation stop signal, the always on circuit block controls the power supply unit to stop supplying the second bias voltage to the non-always on circuit block according to the power down signal, such that the non-always on circuit block enters the second operation mode from the first operation mode.
