BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention is related to a display replicate construct applied in portable information device, especially referring to a replicate construct of display processing device utilized in portable information device. Wherein, the internal of the information device is installed with a connector linked with a high resolution display processing device so as to achieve the purpose of expanding the display efficiency of information device.  
         [0003]     2. Description of the Related Art  
         [0004]     Accordingly, in the busy 21 st  century, the convenient portable information device is a very important work company for the worker, such as notebook computer, which enables the worker to deal with the affairs any time including instantly checking and sending emails, writing reports, and processing general data in the long transport so as to prevent the time-consuming. Moreover, in the long journey, it can relax the exhaustion by playing music or video. In addition, the workers, who frequently have to get out to make a brief presentation or promote the company products, can utilize the portable information device to make the meeting record, brief presentation, or product introduction so that the heavy documentation, presentation data or product advertisement document can be dispensed and further promote the convenience and efficiency on the job.  
         [0005]     Following the people&#39;s demand of computer software, the functions have been becoming ever strong and complete, especially the image processing function. This being the case, the display processing device, installed in the information device, such as display card or display chipset must be high efficiency so as to be compatible with high efficiency computer software, such as 3D graphic software, 3D image processing software, and game software. In comparison, it would take a lot of electricity if using high efficiency display processing device, and if the information device with the high efficiency display processing device runs the low efficiency display software, it would shorten the using life of information device after a long period of time of electricity supply of battery. However, until now, it would cause the inconvenience that the inside of information device can be only installed with just a display processing device.  
         [0006]     In addition, generally the replicate device of portable information device is limited to the externally peripheral storage device such as disk drive, floppy disk, and hard disk. However, all of them would need different interfaces to connect with the portable computer or use a port replicator to achieve the purpose of expanding external peripheral device. Unfortunately, until now, the peripheral devices of replicate pedestal or port replicator in portable information device such as notebook computer don&#39;t include the interface of expanding display processing device, and the user cannot expand and choose the appropriate display processing device according to the desirable display efficiency to enhance the functions of the portable information device and achieve the electricity saving of battery.  
         [0007]     Therefore, to conquer the problem that the portable information device can only have a single display processing device the present invention proposes a kind of display replicate construct applied in the portable information device, wherein there is a connector, which is utilized to install a second display processing device, in the information device, and, according to the running environment of the information device, the user can switch a proper information processing device via a switching module to solve the afore-mentioned problem.  
       SUMMARY OF THE INVENTION  
       [0008]     The purpose of the present invention is to offer a display replicate construct applied in the portable information device, wherein a connector is utilized to connect the chipset of the information device electrically. Further, via the linkage between the connector and another display processing device, it can achieve the purpose of expanding and advancing the display efficiency of information device via the same connector, wherein the connector can be the interface with the dimension of PCI, AGP, or ISA, and is installed internally or externally on the information device.  
         [0009]     Another purpose of the present invention is to offer a display replicate construct applied in the portable information device, wherein the display processing device further comprises a switching module. As the connector is linked with a second display processing device, it can switch the desirable display efficiency via the switching module. For example, when the information device is internally installed with a first display processing device, the user can link a second display processing device via the connector and choose the desirable display processing device through the switching module.

As shown in  FIG. 6 , when the connector  40 ,  44 , or  44 ′ merely link the interface card (such as SCSI card, DVD capture card good TV plus, or TV turner, and etc.), the switching module  30  would be no necessary.  
         [0025]     In conclusion, the present invention is related to a kind of display replicate construct applied in the portable information device, wherein a connector is disclosed to expand the display function of the portable computer. Therefore, the portable computer of low resolution in the conventional art can linked with a high resolution display card via a switching module and a connector to manage the replication of the portable computer. Because of the electrical capacity of the battery, generally the portable computers adopt the display processing devices of low resolution, but it would strongly cause the less practice of the notebook computer than desktop computer because it is unable to switch to the display processing device of high resolution for the notebook computer. Therefore, the present invention is to offer a switching module  30  and a connector  40  so that the user can choose the desirable display processing devices of different resolution via the switching module  30  and the connector  40 .  
         [0026]     In conclusion, this invention definitely achieves creativity, improvement, and more usability for the users in the industry.
