Computer system and control method thereof
First Claim
1. A computer system comprising:
- an input part;
a computer main body; and
a display having a backlight, wherein the computer main body comprising, a video card provided with a data transmitter to transmit data to the display, a system operating part to check whether an input event is generated through the input part and to generate an input event-generating signal and an input event not-generating signal, an event checker to receives the input event not-generating signal if the system operating part generates the input event not-generating signal, and a computer controller to transmit the input event not-generating signal to the display through the data transmitter when the input event not-generating signal is received from the event checker; and
the display comprising, a display controller to control the backlight to be turned off if the input event not-generating signal is transmitted to the display controller.

Abstract
The general inventive concept relates to a computer system comprising an input part, a computer main body and a display having a backlight, the computer main body comprising a video card provided with a data transmitter to transmit data to the display, a system operating part to check whether an input event is generated through the input part and to generate an input event-generating signal and an input event not-generating signal, an event checker to catch the input event not-generating signal if the system operating part generates the input event not-generating signal; and a computer controller to make the input event not-generating signal transmit to the display through the data transmitter when the input event not-generating signal is transmitted from the event checker, the display comprising a display controller to make the backlight keep turned off if the input event not-generating signal is transmitted to the display controller.

7. A control method of a computer system comprising an input part, a display having a backlight and a computer main body having a video card provided with a data transmitter to transmit data to the display, the control method comprising:
-
checking whether an input event is performed at the input part;
generating an input event not-generating signal when an input event is not performed within a predetermined period of time;
receiving a generated input event not-generating signal;
transmitting the input event not-generating signal to the display through the data transmitter; and
controlling the backlight to be turned off when the input event not-generating signal is transmitted. - View Dependent Claims (8, 9, 10)

11. A computer system comprising an input part, a computer main body, and a display, wherein:
-
the computer main body selectively generates an input event not-generating signal; and
the display stops displaying a picture upon receiving the input event not-generating signal while the computer main body is turned on. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
