   BACKGROUND OF INVENTION 
   1. Field of Invention 
   The present invention relates to a display panel, and more particularly, to a display panel with the integrated driver circuit composed of the Low Temperature Poly-Silicon (LTPS) Thin Film Transistor (TFT). 
   2. Description of Related Art 
   The Liquid Crystal Display (LCD) is one kind of the panel display. It is classified into the static driving, simple matrix driving, and the active matrix driving types based on various LCD driving methods. The TFT is the mainstream active matrix driving technique and is mainly applied in the notebook computer as well as in the camcorder and image processing products. The Twisted Nematic (TN) and the Super Twisted Nematic (STN) are the mainstream simple matrix driving techniques mainly applied in word processors and consumer products. The active matrix driving LCD is an ideal display apparatus for providing the display effect with high data density. 
   With the LTPS technique, the horizontal driver circuit and the vertical driver circuit are disposed on the peripheral areas of the display panel,therefore the number of the panel driver ICs and the space occupied by the panel peripheral areas are both reduced, thus the product is advantageous in its low cost and slim edge size. Since the LTPS technique intragrates the driver circuit on the panel peripheral areas, the resolution of such panel is much higher than the resolution provided by the currently used a-Si TFT-LCD. 
     FIG. 4  schematically shows a conventional display panel with the integrated driver circuit. As shown in  FIG. 4 , the display panel with the integrated driver circuit  400  comprises an array substrate  402  and further comprises a liquid crystal injection hole  410 , a display area  420 , a gate driver circuit  430 , a data driver circuit  440 , a first peripheral area  456 , a second peripheral area  454 , a third peripheral area  458 , and a forth peripheral area  452 . 
   In conventional display panel with the integrated driver circuit  400 , the liquid crystal injection hole  410  is disposed on the forth peripheral area  452  of the array substrate  402 , the gate driver circuit  430  is disposed on the third peripheral area  458  of the array substrate  402 , and no driver circuit is disposed on both the first peripheral area  456  and the second peripheral area  454  of the array substrate  402 . The data driver circuit  440  is disposed within a range formed by the liquid crystal injection hole  410  and the display area  420 , in other words, the data driver circuit  440  is disposed under the liquid crystal injection hole  410 . When the designer of the display panel  400  is designing the integrated driver circuit, the impact caused by the poor configuration of the liquid crystal injection hole  410  and the data driver circuit  440  has to be considered, as, for example, the damage caused by the sealing process of injection hole  410  to the data driver circuit  440  after liquid crystal injection has to be avoided. 
   In summary, since the liquid crystal injection hole and the data driver circuit of the conventional display panel with integrated driver circuit are disposed on the same side, it is rather inconvenient for the designer when it is under designed. 
   SUMMARY OF INVENTION 
   To solve the problem mentioned above, the present invention provides a display panel with the integrated driver circuit. The present invention changes the original design where the liquid crystal injection hole and the data driver circuit are originally disposed on the same peripheral area of any array substrate in the display panel to a new design where the data driver circuit is disposed on the adjacent edge of the first peripheral area and the second peripheral area of the array substrate, and the liquid crystal injection hole is disposed on the fourth peripheral area of the array substrate, so as to avoid inconvenience when the display panel is under design.

The injection hole is a hole where the liquid crystal is injected into and is disposed on the fourth peripheral area of the array substrate, and after the injecting liquid crystal process is completed; the injection hole is sealed with a sealing material. 
   In accordance with the preferred embodiment of the present invention, the display area mentioned above is composed of a plurality of data lines and a plurality of gate lines that are perpendicularly crossed with each other, and the display area is an active matrix driving display area.

Optionally, the second driver circuit is disposed on the third peripheral area of the array substrate and part of the first peripheral area where the first driver circuit is not disposed on, wherein the second driver circuit is a gate driver circuit. 
   In accordance with the preferred embodiment of the present invention, the first driver circuit mentioned above is disposed on either all of the first peripheral area and part of the second peripheral area or part of the first peripheral area and part of the second peripheral area. When the second driver circuit is disposed on the third peripheral area of the array substrate and the part of the first peripheral area where the first driver circuit is not disposed on, it can be partially disposed or fully disposed on the third peripheral area. 
   The display panel with the integrated driver circuit provided by the present invention disposes the first driver circuit on the first peripheral area and the second peripheral area of the array substrate, and disposes the liquid crystal injection hole on the fourth peripheral area, so as to facilitate the designer of the display panel when designing the circuit.

The first driver circuit  140  is disposed on the adjacent edge of the first peripheral area  156  and the second peripheral area  154  of the array substrate  102 . As shown in  FIG. 1 , the first driver circuit  140  on the second peripheral area  154  is only partially disposed on the second peripheral area  154 . It will be apparent to one of the ordinary skill in the art that the first driver circuit  140  may be a data driver circuit or a gate driver circuit. However, it is not necessarily limited to it.
