A method and a device for power management regarding an integrated display unit including a video display and at least one peripheral device, wherein the video display uses horizontal and vertical sync signals for the synchronization of the display images, and the peripheral device uses a peripheral signal to carry out its function. The peripheral device can be an audio unit using audio signals to produce sound. The peripheral device can be a USB connector using a +5 V voltage to indicate a connection being made to the integrated display unit. In the integrated display unit, a single power supply is used to provide electrical power to the video display and the peripheral device. In order to reduce the power consumption by the integrated display unit, a number of power consumption states, based on the presence of the video sync signals and the peripheral signals, are implemented. The presence of the video sync signals can be detected by a micro-controller in the integrated display unit. Alternatively, the presence of the video sync signals or data indicating power save states is signaled to the integrated display unit via USB BUS or other digital communication mean. Likewise, audio signals can be sent as digital data via USB BUS to the integrated display unit.
In an integrated display unit having a video display for displaying images, at least one peripheral device having a first signal associated therewith, and a power supply to supply electrical power to both the video display and said at least one peripheral device, wherein the video display uses a horizontal sync signal and a vertical sync signal for the synchronization of the displayed images, a method for reducing the power consumption of the integrated display unit by implementing a plurality of power consumption states, each state having a different level of power consumption, said method comprising the steps of:
In an integrated display unit having a video display for displaying images, at least one peripheral device, and a power supply to supply electrical power to both the video display and said at least one peripheral device, wherein the video display uses a horizontal sync signal and a vertical sync signal for the synchronization of the displayed images and wherein said at least one peripheral device uses a first signal to carry out a function associated with said peripheral device, a method for reducing the power consumption of the integrated display unit by causing the power supply to enter different output modes comprising the steps of:
In an integrated display unit having a video display for displaying images, at least one peripheral device, and a power supply to supply electrical power to both the video display and said at least one peripheral device, wherein the display uses a horizontal sync signal and a vertical sync signal for the synchronization of the displayed images and wherein said at least one peripheral device has a first signal associated with said peripheral device, wherein the power supply is caused to enter different output modes for reducing power consumption of the integrated display unit, a device for effecting the reduction of the power consumption comprising:
