Description:
1. FIELD OF THE INVENTION  
       [0001]     The present invention relates to a display, and more particularly, to a display having a non-rectangle display panel.  
       2. BACKGROUND OF THE INVENTION  
       [0002]     Nowadays, flat panel displays are widely used in various products such as computers, mobile phones, TVs, digital cameras, digital video cameras, watches, personal stereos, car/motorcycle instrument panels, signboards, and so on. However, shapes of conventional liquid crystal panels are always limited to be rectangular, which limits the use of such display. By virtue of this, the visual figure of a common video wall, which is made up of a plurality of rectangular displays, is also limited to be rectangular.  
         [0003]     Referring to  FIGS. 1A, 1B ,  1 C and  1 D that if the display panel is nonrectangular, the use of such display panel will be widened and thus the economic value of the display panel is increased. For example, a display panel functioned as a mirror can be designed to be elliptic (now shown), a display panel  11  of a mobile phone  1  can be shaped as an octagonal display panel  12  (shown in  FIG. 1A ), a display panel  21  of a digital camera  2  can be shaped as a circular display panel  22  (shown in  FIG. 1B ), a car instrument panel  3  can be shaped as a semicircular display panel  31  (shown in  FIG. 1C ), and a traffic signboard  4  can be shaped as a triangular display panel  41  (shown in  FIG. 1D ).  
         [0004]     Due to limitation of technology and material, the conventional display panel is inflexible and thus products employing such display panel are mostly in a simply rectangular shape. It is desired to design a non-rectangle display enabling a display wall to be combined by a plurality of non-rectangle displays for meeting the more versatile demands of the future while flexible display panel becoming popular.  
       SUMMARY OF THE INVENTION  
       [0005]     It is the primary object of the present invention to provide a non-rectangle display having a non-rectangle shaped display panel for meeting the demands of versatile usage.  
         [0006]     It is another object of the present invention to provide a display wall composed of a plurality of non-rectangle displays, which is capable of enlarging video display by a specific means of signal transmission and distribution and functioning similar to a common TV wall.  
         [0007]     To achieve the above objects, the present invention provides a non-rectangle display, comprising: a circuit substrate, and a display panel connected with the circuit substrate. The circuit substrate has a driving device for driving the display panel to display video. The driving device includes at least one data line driver and at least one scan line driver. Each data line driver and each scan line driver are respectively disposed at least one side of the display panel. The data line driver and the scan line driver cooperatively drive the display panel. The display panel has a peripheral profile of at least one specific function curve.  
         [0008]     Other objects, advantages and novel features of the present invention will become apparent upon study of the remaining portions of the specification and drawings.

     DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0019]     Referring to  FIGS. 2A, 2B  and  2 C, which are schematic views of panels of non-rectangle displays with different shapes according to the present invention. As shown in  FIG. 2A , an octagonal display panel  6  is pasted with a color filter (not shown), having a plurality of evenly arranged pixels  61 , wherein each pixel  61  employs the red-green-blue (RGB) additive color system. As shown in  FIG. 2B , a circular display panel  7  is pasted with a color filter (not shown), having a plurality of evenly arranged pixels  71 , wherein each pixel  71  employs the red-green-blue (RGB) additive color system. As shown in  FIG. 2C , a triangular display panel  8  is pasted with a color filter (not shown), having a plurality of evenly arranged pixels  81 , wherein each pixel  71  employs the red-green-blue (RGB) additive color system. Currently a base panel fabricated by a common panel factory is simply a large piece of rectangular panel, which is already pasted with a color filter and has pixels evenly arranged therein.  
         [0020]     Referring to  FIG. 3 , a flow chart shows a fabricating process of a common LCD (liquid crystal display) a cutting step for forming a non-rectangle display of the present invention. The fabricating process  30  includes the steps of: 
        step  301 : providing a thin film transistor (TFT) substrate and a color filter (CF) substrate;     step  302 : cleaning/coating/curing/aligning the TFT substrate and the CF substrate before PI (polyimide) processing;     step  303   a : spraying spacers on/dispensing a silver glue on/cleaning the TFT substrate after alignment;     step  303   b : coating the CF substrate with a sealant and then cleaning the CF substrate after alignment;     step  304 : aligning the TFT substrate and the CF substrate for integrating the two by hot pressing;     step  305 : proceeding with a shape cutting process;     step  306 : injecting liquid crystal and sealing/cleaning and realigning/grinding, cleaning and pasting/inspecting electrically and visually; and     step  307 : proceeding with a module installing process.        
 
         [0029]     In the present invention, the display panels can be cut in accordance with actual demands and so result in different shapes of display panels. The cutting process is generally processed at the posterior of cell processing, that is, after the process of aligning the TFT substrate (i.e. step  304 ) and the CF substrate for integrating the two by hot pressing and before the process of liquid crystal injection and seal (i.e. step  306 ). As to a glass substrate, the process of shape cutting can be processed using a laser or diamond blade. As to a plastic substrate, the process of shape cutting can be processed by a method of stamping.  
         [0030]     Referring to  FIG. 4 , a top plan view of a non-rectangle display in accordance with an embodiment of the present invention is shown. The non-rectangle display  5  includes a circuit substrate  51  and a display panel  52 . The circuit substrate  51  has a scan line driver  53  and a data line driver  54 , wherein the scan line driver  53  includes scan line ICs  531 ,  532 ,  533  configured at one side of the display panel  52 , and the data line driver  54  includes data line ICs  541 ,  542 ,  543  configured at another side of the display panel  52 . In this embodiment, the display panel  52  is an octagonal display panel. Of cause, the display panel  52  may be in any of other geometrical shapes except for rectangle.  
         [0031]     As shown in  FIG. 4 , a plurality of horizontal lines  521  formed on the display panel  52  are scan lines and respectively connected with the scan line ICs  531 ,  532 ,  533 , and a plurality of vertical lines  522  formed on the display panel  52  are data lines and respectively connected with the data line ICs  541 ,  542 ,  543 .  
         [0032]     In operation, a signal S is transmitted through the circuit substrate  51  to both the scan line driver  53  and the data line driver  54 , such that the scan line driver  53  and the data line driver  54  are enabled for respectively driving the scan line ICs  531 ,  532 ,  533  and the data line ICs  541 ,  542 ,  543  to activate the horizontal lines  521  and the vertical lines  522  for start scanning respectively. In this regard, the display panel  52  is driven to display video through cooperative operation of the horizontal lines  521  and the vertical lines  522 .  
         [0033]      FIG. 5  is a schematic view of a display wall combined by a plurality of non-rectangle displays of the present invention. The display wall  9  is composed of four triangular displays  91 ,  92 ,  93 ,  94  of the same shape, wherein the triangular display  91  has a scan line driver  911  arranged at one side thereof; the triangular display  92  has scan line drivers  921 ,  922  respectively arranged at opposite sides thereof; the triangular display  93  has a scan line driver  931  arranged at one side thereof; and the triangular display  94  has a scan line driver  941  arranged at one side thereof.  
         [0034]     When the display wall  9  is in operation while focusing only on the operation of the scan lines herein, the scanning order of the scan lines is described as follows. The scan line driver  941  firstly emits a horizontal scan line  9411 . When the scan line  9411  is about to finish scanning, the scan line driver  911  subsequently emits another horizontal scan line  9111  at the same horizontal position. Then when the scan line  9111  is about to finish scanning, the scan line driver  921  subsequently emits another horizontal scan line  9211  at the same horizontal position. Therefore, the combined horizontal scanning operation of the scan line drivers  941 ,  911 ,  921  may be regarded as a continuous scanning operation. Similarly, display signal emission operation (not shown) of the vertical lines is also regarded as a continuous emission operation. Thus, the displayed videos of the triangular displays  91 ,  92 ,  93 ,  94 , can match each other through the scan lines and the data lines to cooperatively drive the triangular displays  91 ,  92 ,  93 ,  94 , that is, the display wall  9  can enlarge single video display thereby having an effect of a video wall.  
         [0035]     However, the above-mentioned triangular display wall is only one embodiment of application of the non-rectangle display of the present invention for illustration but not limitation. A display wall combined by any quantity of the non-rectangle displays in any shapes should fall within the scope of the present invention as long as the scan line driver and the data line driver can cooperatively work.  
         [0036]     In the embodiment of the present invention, the circuit substrate may be a flexible print circuit (FPC) with a circuit layout formed therein, or a chip on film (COF). In addition, the circuit layout may be directly formed at the display panel (e.g. glass) through a low temperature polysilicon (LTPS) process.  
         [0037]     While the preferred embodiment of the invention has been set forth for the purpose of disclosure, modifications of the disclosed embodiment of the invention as well as other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
