Abstract
The invention provides a notebook computer with an external display card. When 3D processing ability is acquired, the notebook computer can externally connected with the display card of a common desktop computer, which greatly improves the 3D processing ability of the notebook computer; when the notebook computer is used outdoor or only common application is needed, the external display card can be removed, like a common notebook computer. The external display card is added to the common notebook computer, which connects with an output interface for the external display card and an input interface for display signals, the notebook computer without the external display card can operate with an internal integrated display card, and the notebook computer with the external display card being connected with the output interface switched to the external display card to operate.
Description
The present invention relates to a kind of notebook computer, mainly be suitable for the recreation and the amusement of family, also can be used for the professional user that video card is had relatively high expectations.
At present, the video card great majority of notebook computer are integrated, can reduce power consumption like this and reduce cost, but the 3D processing power of integrated graphics card a little less than, can not move recreation and program that some are had relatively high expectations to 3D, sell though also have with the notebook computer of independent video card, it is higher that it sells lattice, the 3D processing power is also less than the desktop-use graphics chip with class, and upgrading is very inconvenient.
In order to overcome existing notebook computer deficiency, the invention provides a kind of notebook computer with external video card, when this notebook computer needs the higher application of 3D processing power, video card that can external common desktop computer, significantly improve the 3D processing power of notebook computer, when this notebook computer is gone out and only need common application, can remove external video card part, the same with common notebook computer.
The technical solution adopted for the present invention to solve the technical problems is: increase an external video card and connect output interface and a shows signal input interface on the basis of common notebook computer, when not having external video card, notebook computer can be with built-in integrated graphics card work, be connected to video card as external video card and connect output interface, notebook computer is transferred to external video card work.
The present invention is easy to use, and the 3D performance of notebook computer is had bigger lifting, can with the video card compatibility of common desktop computer, and upgrading is convenient.
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a circuit block diagram of the present invention.
Fig. 2 is an embodiment of the invention notebook computer interface schema behind.
Fig. 3 is the structural drawing of the external video card adapter of the embodiment of the invention.
Fig. 4 is the connection layout of embodiment of the invention notebook computer and external video card adapter.
Fig. 1 is a circuit block diagram of the present invention.By central processing unit 1, north bridge chips 2, internal memory 3, integrated graphics card 4, switch 5, display screen 6, show input interface 7, independent video card interface 8, external independent video card 9, external video card power supply 10, South Bridge chip 11, BIOS 12, external interface 13, and hard disk 14, CD-ROM drive 15, sound card 16 and network interface card 17 are formed.Wherein central processing unit 1, north bridge chips 2, and internal memory 3, integrated graphics card 4, display screen 6, South Bridge chip 11, BIOS 12, external interface 13, hard disk 14, CD-ROM drive 15, sound card 16 is identical with common notebook computer with network interface card 17.Independent video card interface 8 is independent video card interfaces of north bridge chips 2, can be PCI-E, it also can be the video card interface of other type, the video card that external independent video card 9 is common desktop computers adds external video card adapter, because the power consumption of the video card of common desktop computer is all bigger, notebook computer can not satisfy power supply, so need external video card power supply 10 to come to external independent video card 9 power supplies.What show that input interface 7 inserts external independent video card 9 outputs signal to switch 5, switch 5 is when detecting when showing that input interface 7 has the signal input, just switch is transferred to demonstration input interface 7, when showing that input interface 7 does not have the signal input, then switch is forwarded to integrated graphics card 4.Switch 5 also can be by manually being transformed into needed position.
Fig. 2 is an embodiment of the invention notebook computer interface schema behind, and wherein 210 is notebook computers, the 220th, and the shows signal input interface, the 230th, external video card connects output interface, the 240th, video output interface, the 250th, USB interface.
Fig. 3 is the structural drawing of the external video card adapter of the embodiment of the invention, the 310th, and the power unit of external video card adapter, the 320th, electric power connection line is used for power supply to external independent video card, the 330th, the connection input interface of external video card.The 340th, fixed screw.The 350th, common desktop-use graphics chip socket.The 360th, the pcb board of usefulness is installed, have above to be used for the circuit that is connected with notebook computer, the 370th, the shows signal output interface of common desktop-use graphics chip.The 380th, the video card of common desktop computer, the 390th, the external power supply interface of common desktop-use graphics chip.
Fig. 4 is the connection layout of embodiment of the invention notebook computer and external video card adapter, the 410th, and the power lead of external independent video card adapter and power supply adapter for notebook computer 420 is used for connecting the civil power input.The 210th, notebook computer, the 450th, external video card adapter, the 440th, signal connecting line, be used for connecting the shows signal output interface 370 of common desktop-use graphics chip and the shows signal input interface 220 of notebook computer, the 430th, connecting line is used for connecting the external video card connection output interface 230 of notebook computer and the external video card of video card adapter is connected input interface 330.
