Description

Control device of power for monitor and computer system and the method

The present invention relates to a power control device and a method of the monitor and the computer system, and more specifically to the power control of the monitor and computer system in which both sides are off at the same time even when only one of the power off each other by interlocking the power of the monitor and the computer system An apparatus and a method thereof are provided.

In general, DDC-CI (Display Data Channel Command Interface) transmission method is applied to a computer system. DDC-CI defines a communication channel between a peripheral device such as a monitor and the main body of a computer, for example, and monitor information stored in a monitor. Is a communication protocol for transmitting the information to the computer system body or changing the monitor information through a keyboard or a mouse.

According to the DCS-CI's Monitor Control Command Set (MCCS) specification, four power saving modes are supported from S0 to S3 as the power saving mode associated with the monitor. It corresponds to the Standby, Suspend, and Off phases. The On stage means a normal use environment, and the Standby phase shuts off power to some circuits of the monitor, allowing the monitor to wake up within three seconds. In addition, the suspend stage means the minimum power consumption, and the off stage means the monitor is turned off.

On the other hand, power consumption in the general office, according to US market researcher Gartner statistics, monitors are the highest at 39%, requiring a solution.

However, in the display properties of a general computer system, power off of the monitor, system standby mode, system hibernation mode, etc. of the power option properties are divided by time, and the setting information can only be stored and controlled, which causes a lot of power loss.

In addition, since the monitor and the computer system cannot be controlled separately, it is inconvenient to turn off the power at the same time in order to shut down the power.

That is, even after shutting down the operating system, the monitor had to be turned off separately, and when the computer system was started and the operating system was started, there was a problem in that the monitor was turned off again.
