[embodiment]
Please refer to shown in Figure 1ly, be system's block schematic diagram of the computer system of disclosed the first embodiment of the present invention.
The disclosed computer system 10 of first embodiment of the invention includes a circuit board 100, a display card 400 and a power-supply control unit 500.Electrically be provided with a processing unit 200, a display chip 300 and a connecting interface 110 on circuit board 100, and processing unit 200 is electrically connected at respectively display chip 300 and connecting interface 110, wherein processing unit 200 is controlled signal to display chip 300 and display card 400 in order to produce corresponding power supply, therefore processing unit 200 can be but be not limited to central processing unit (central processing unit, CPU), or, processing unit 200 can be also a power management chip, is not limited with the embodiment revealer of institute.
In addition, dispose a power switch 410 on display card 400.Power-supply control unit 500 namely is electrically connected at 200 of the processing units of the power switch 410 of display card 400 and circuit board 100, make processing unit 200 when optionally activation (enable) display chip or display card, can transmit power supply by power-supply control unit 500 and control signal to display card 400, for example transmit a forbidden energy signal (disable signal) or an activation signal (enable signal) to display card 400, close or open the power switch 410 of display card 400 with correspondence.
For example, when processing unit 200 optionally during activation display chip 300, make display chip 300 produce running by the driving power that processing unit 200 receives from circuit board 100, simultaneously, processing unit 200 produces forbidden energy (disable) signal, and by power-supply control unit 500, the forbidden energy signal is sent to display card 400, with powered-down switch 410.And when processing unit 200 activation display card 400, the enable signal that processing unit 200 produces is to be sent to display card 400 by power-supply control unit 500, with power-on switch 410.
Wherein, in the running of computer system 10, processing unit 200 can be but be not limited to activation display chip 300 normally, closes simultaneously the power switch 410 of display card 400, makes display chip 300 become the default image output of computer system 10 and originates.Then, processing unit 200 determines whether carrying out according to the use state of other application software in computer system 10 again and switches at display chip 300 and 400 of display cards.For example, when computer system 10 is carried out the application software of the low demonstration performance requirements such as normal words process software or web page browsing software, processing unit 200 is namely selected with the image output source of the display chip 110 on circuit board 100 as computer system 10, and close the power switch 410 of display card 400, with the power supply of the consumption calculations machine system 10 that avoids that display card 400 continues.In addition, when computer system 10 execution mapping softwares or computer game software etc. need the application software of higher demonstration usefulness, processing unit 200 transmits enable signal to display card 400 by power-supply control unit 500, to open the power switch 410 of display card 400, computer system 10 can be originated by display card 400 as the image output of computer system 10.Therefore, by this optionally power supply switching mode, allow the image output usefulness of computer system 10 can reach optimized application.
In addition, in order further to allow the power supply of computer system 10 obtain effectively to utilize, open the power switch 410 of display card 400 when processing unit 200, when waking display card 400 up, processing unit 200 can synchronously cut off the driving power that circuit board 100 is supplied to display chip 300, with forbidden energy display chip 300, and then the loss of the image output power supply of reduction computer system 10.
It should be noted that, the display card 400 of the computer system 10 of the present embodiment can be an external display card, or, the display card 400 of the computer system 10 of the present embodiment can be also another computer peripheral apparatus with display chip, and the pattern of above-mentioned display card 400 is not limited to the disclosed enforcement aspect of the present invention.
