BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to an interface card with a control chip located on a side opposite to a side where a connector is located, and more particularly, to a display card with a graphics processing unit located on a side opposite to a side where a connector is located.  
         [0003]     2. Description of the Prior Art  
         [0004]     In modern information society, computer systems are becoming necessities, such as desktops, notebook computers, servers, and so on. The operation speed of computers is getting faster and faster so that the computer is becoming powerful and is utilized in a wide variety of fields. Therefore, components of the computer generate more heat when processing operations than before. If the heat generated by the components of the computer cannot be dissipated effectively, the stability and operation speed of the computer will be reduced.  
         [0005]     Please refer to  FIG. 1 .  FIG. 1  is a diagram of a display card  10  inserting into a motherboard  12  according to the prior art. The motherboard  12  includes a plurality of slots  14  which can conform to a standard of Peripheral Component Interface-Express (PCI-E), Peripheral Component Interface (PCI), and so on. A plurality of interface cards  16  is inserted into the slots  14 . The interface card  16  can be a sound card, a SCSI card, a network card, and so on. The motherboard  12  further includes a display slot  18  which can conform to a standard of Peripheral Component Interface-Express, Peripheral Component Interface, Accelerated Graphics Port interface, and so on, and the display card  10  is inserted into the display slot  18  for processing image signals.  
         [0006]     Please refer to  FIG. 1 ,  FIG. 2 , and  FIG. 3 .  FIG. 2  is a front view of the display card  10  shown in  FIG. 1  according to the prior art.  FIG. 3  is a back view of the display card  10  shown in  FIG. 1  according to the prior art. The display card  10  includes a circuit board  20  which can be a printed circuit board, and a bracket  22  connected to the circuit board  20  for wedging in an opening of a casing (not shown in figures). The bracket  22  can be an L-shaped bracket. A plurality of connectors  24  is positioned on the bracket  22  for outputting or receiving image signals. The connectors  24  are positioned on the front side A 1  of the circuit board  20  of the display card  10 , wherein the front side A 1  is a front side of the circuit board  20  when the bracket  22  is on the left of the circuit board  20 , and a back side A 2  is a front side of the circuit board  20  when the bracket  22  is on the right of the circuit board  20 . The display card  10  further includes a graphics processing unit  26  installed on the front side A 1  of the circuit board  20  for controlling operation of the display card  10 , and golden fingers  28  for inserting in the display slot  18  of the motherboard  12 . The golden fingers  28  can conform to a standard of Peripheral Component Interface-Express (PCI-E), Peripheral Component Interface (PCI), Accelerated Graphics Port interface, and so on. The interface of the golden fingers  28  needs to match the interface of the display slot  18 . The golden fingers  28  include a front side  28   a  and a back side  28   b  defined according to the specification of the golden fingers  28 , such as PCI, PCI-E, AGP, and so on. The front side  28   a  of the golden fingers  28  and the front side A 1  of the circuit board  20  are located on the same side, and the back side  28   b  of the golden fingers  28  and the back side A 2  of the circuit board  20  are located on the same side. The display card  10  further includes a plurality of video memories  30  installed on the circuit board  20 . The video memories  30  can be installed on the front side A 1  or the back side A 2  of the circuit board  20 .  
         [0007]     As shown in  FIG. 1 , conventionally the graphics processing unit  26  is positioned on the front side A 1  of the circuit board  20 , that is, on the same side as the front side  28   a  of the golden fingers  28 . Hence the graphics processing unit  26  is located between the circuit board  20  and a neighboring interface card  16 . Especially for a motherboard of ATX specification, the front side A 1  of the circuit board  20  of the display card  10  is close to the neighboring interface card  16 . When the graphics processing unit  26  processes complicated operations, such as 3D image processing, so as to generate lots of heat, the heat cannot be dissipated easily due to the narrow space between the display card  10  and the neighboring interface card  16  because of the short gap between the slot  14  of the motherboard  12  and the display slot  18 , so that the temperature of the display card  20  will increase and the stability of the computer and the service life of the display card  10  will be reduced.  
         [0008]     For solving the heat-dissipating problem of the graphics processing unit  26  of the display card  10 , a fan can be installed on the display card  10  and a heat pipe can be applied to transmit heat generated by the graphics processing unit  26  to a heat sink (not shown in figures) positioned on the back side A 2  of the circuit board  20 . But the above-mentioned solutions can not solve the heat-dissipating problem effectively and the cost of the display card  10  will increase.

The motherboard  52  further includes a display slot  58  which can conform to a standard of Peripheral Component Interface-Express, Peripheral Component Interface, Accelerated Graphics Port interface, and so on, and the display card  50  inserts in the display slot  58  for processing image signals.  
         [0021]     Please refer to  FIG. 4 ,  FIG. 5 , and  FIG. 6 .  FIG. 5  is a front view of the display card  50  shown in  FIG. 4  according to the present invention.  FIG. 6  is a back view of the display card  50  shown in  FIG. 4  according to the present invention. The display card  50  includes a circuit board  60  which can be a printed circuit board, and a bracket  62  connected to the circuit board  60  for wedging in an opening of a casing (not shown in figures). The bracket  62  can be an L-shaped bracket. A plurality of connectors  64  is positioned on the bracket  62  for outputting or receiving image signals. The connectors  64  are positioned on the front side A 1  of the circuit board  60  of the display card  50  wherein the front side A 1  is a front side of the circuit board  60  when the bracket  62  is on the left of the circuit board  60 , and a back side A 2  is a front side of the circuit board  60  when the bracket  62  is on the right of the circuit board  60 . The display card  50  further includes a graphics processing unit  66  installed on the back side A 2  of the circuit board  60  for controlling operation of the display card  50 , and golden fingers  68  for inserting in the display slot  58  of the motherboard  52 . The golden fingers  68  can conform to a standard of Peripheral Component Interface-Express (PCI-E), Peripheral Component Interface (PCI), Accelerated Graphics Port interface, and so on. The interface of the golden fingers  68  needs to match the interface of the display slot  58 . The golden fingers  68  includes a front side  68   a  and a back side  68   b  defined according to the specification of the golden fingers  68 , such as PCI, PCI-E, AGP, and so on. The front side  68   a  of the golden fingers  68  and the front side A 1  of the circuit board  60  are located on the same side, and the back side  68   b  of the golden fingers  68  and the back side A 2  of the circuit board  60  are located on the same side. The display card  50  further includes a plurality of video memories  70  installed on the circuit board  60 . The video memories  70  can be installed on the front side A 1  or the back side A 2  of the circuit board  60 .  
         [0022]     The graphics processing unit  66  is positioned on the back side A 2  of the circuit board  60 , that is, on the same side as the back side  68   b  of the golden fingers  68  instead of being located between the circuit board  60  and a neighboring interface card  60 . Especially for a motherboard of ATX specification, the front side A 1  of the circuit board  60  of the display card  50  is close to the neighboring interface card  56  and the back side A 2  of the circuit board  60  of the display card  50  is not close to any interface card so that there is enough space for dissipating heat. That is, because the graphics processing unit  66  is positioned on the back side A 2  of the circuit board  60 , the heat generated by the graphics processing unit  66  can be dissipated effectively instead of being blocked by other interface card  56 .  
         [0023]     Besides the above-mentioned embodiment, the present invention discloses that a control chip can be installed on the back side of the interface card, such as a sound card, a SCSI card, a network card, and so on.  
         [0024]     In contrast to the conventional display card, the graphics processing unit of the display card according to the present invention is installed on the back side of the display card so that there is enough space for dissipating heat generated by the graphics processing unit instead of being blocked by other interface card. Therefore, heat generated by components of the computer can be dissipated effectively so that the stability of the computer and the service life of the display card will increase. Additionally, the present invention does not need to utilize additional thermal modules for dissipating heat generated by the graphics processing unit so that the cost of the display card can be reduced.  
         [0025]     Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
