Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a liquid crystal display field, more particularly, to a Film-type Patterned Retarder (FPR) liquid crystal display panel and a liquid crystal display device for 3D display. 
         [0003]    2. Description of the Prior Art 
         [0004]    With continuous development for display technology, 3D display technology is maturing. 3D image devices, such as 3D TV, 3D projection, 3D camera, etc, are invented. Compared with 2D display technique, 3D display technique displays images more lifelike to have a better vision effect and becomes mainstream development for display devices in the future. 
         [0005]    Film-type Patterned Retarder (FPR) display is one of imaging mode for 3D liquid crystal display in the prior art. As  FIG. 1  shows,  FIG. 1  is an operating principle diagram of a conventional FPR 3D display system. The FPR 3D display system comprises a liquid crystal display panel  11 , a patterned retarder film  12  and a pair of patterned retarder glasses  13 . The liquid crystal display panel  11  comprises pixels  16  showing left-eye signals, pixels  17  showing right-eye signals and a black matrix  18  therebetween. The FPR 3D display system separates a 3D image into a left-eye image  14  and a right-eye image  15  by the patterned retarder film  12  adhering onto the liquid crystal display panel  11 . The left-eye image  14  and the right-eye image  15  are viewed by the user&#39;s left eye and right eye respectively via the patterned retarder glasses  13 . Finally, user&#39;s brain synthesizes 3D image according to two sets of the images from the left and right eye. 
         [0006]    The operating principle of the liquid crystal display panel  11  is illustrated in  FIGS. 2A and 2B .  FIG. 2A  is a structure diagram of a conventional liquid crystal display panel, and  FIG. 2B  is a timing diagram of driving signals applied in the conventional liquid crystal display panel. When the liquid crystal display panel is operating, a thin-film transistor (TFT)  22  turns on in response to a scan signal  21 , and pixels in each row are charged by data signals  23 . Therefore, each pixel  24  incorporating with backlight and a patterned retarder film shows various grey levels according to rotation of the liquid crystal. The scan signal  21  is triggered by a CKV clock signal  25 . Each scan signal  21  in  FIG. 2A  controls one row of pixels  24  to turn on or off. The data signal  23  is triggered by a TP (triggering pulse) signal  26 . Each data signal  23  in  FIG. 2A  controls grey level displayed by one column of pixels  24 , whereas the display pixels  24  in odd rows display left-eye signal images (the data signal  23  is left-eye image signal  231 ), the display pixels  24  in even rows display right-eye signal images (the data signal  23  is right-eye image signal  232 ). The left-eye and right-eye signal images are respectively received by user&#39;s left eye and right eye via the patterned retarder film  12  and the patterned retarder glasses  13 . Finally, the brain synthesizes 3D image according to the received left-eye and right-eye signal images. Since two display pixels in adjacent rows of the liquid crystal display panel  11  is very close as  FIG. 1  shows, it occurs crosstalk between the left-eye signal image and the right-eye signal image when viewing at a larger viewing angle, which means the right-eye images is viewed by the left eye, to influence a display effect of the liquid crystal display panel.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0040]    Spatially relative terms, such as “beneath”, “below”, “lower”, “above”, “upper” and the like, may be used herein for ease of description to describe one element or feature&#39;s relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. 
         [0041]    Please note, the same components are labeled by the same number. 
         [0042]    Please refer to  FIG. 3A ,  FIG. 3A  is a structure diagram of a liquid crystal display panel according to a preferred embodiment of the present invention. The FPR liquid crystal display panel for 3D display comprises a plurality of display pixels  34 , data lines  37 , scan lines  38  and TFTs  32 . The data lines  37  are used for inputting data signals to the display pixels  34 , the scan lines  38  are used for inputting scan signals to the display pixels  34 , and the TFTs  32  are used for charging liquid crystal in display pixels by the data signal in response to the scan signal. The display pixels  34  comprise first display pixels and second display pixels. The first display pixels and the second display pixels are arranged alternatively in row (for instance, the first display pixels are the display pixels  34  in odd rows, and the second display pixels are the display pixels  34  in even rows, or the first display pixels are the display pixels  34  in even rows, and the second display pixels are the display pixels  34  in odd rows). The first and second display pixels are fed with data signal upon receiving scan signals. The second display pixels display black images while the first display pixels display signal images, or the first display pixels display black images while the second display pixels display signal images. In hence, the display pixels displaying signal images are separated by the display pixels displaying black images, thereby increasing intervals between display pixels displaying display signal images. Therefore, it effectively prevents from crosstalk between signal images and assures a display effect of a liquid crystal display panel. 
         [0043]    The following illustrates a driving process of the liquid crystal display panel according to the present invention in  FIG. 3B to 6B . 
         [0044]    Please refer to  FIG. 3B ,  FIG. 3B  is a timing diagram of driving signals applied on a liquid crystal display panel according to a first preferred embodiment of the present invention. In the preferred embodiment, the liquid crystal display panel stops inputting the data signals  33  to the second display pixels through the scan signals  31  and inputs the left-eye image signal  331  and the right-eye image signal  332  alternatively to the first display pixels in the same frame when displaying signal images through the first display pixels. The liquid crystal display panel stops inputting the data signals  33  to the first display pixels through the scan signals  31  and inputs the left-eye image signal  331  and the right-eye image signal  332  alternatively to the second display pixels in the same frame when displaying signal images through the second display pixels. 
         [0045]    As  FIG. 3  shows, the scan signals  31  are triggered by the CKV signal  35 , each of the scan signals  31  controls one row of display pixels to turn on or off, the data signals  33  are triggered by the TP signal  36 , each of the data signals  33  controls one column of signal images of display pixels. When the liquid crystal display panel of the preferred embodiment works, the scan signals  31  turn correspondent display pixels on, and in the same frame, the scan signals  31  turn all display pixels in odd rows on in order and all display pixels in even rows off while inputting the left-eye image signal  331  and the right-eye image signal  332  alternatively. Therefore, the display pixels in the first row of the liquid crystal display panel display the left-eye image signal  331 , those in the second row display none, those in the third row display the right-eye image signal  332 , those in the fourth row display none, . . . those in the (4n+1) row display the left-eye image signal  331 , those in the (4n+2) row display none, those in the (4n+3) row display the right-eye image signal  332 , and those in the (4n+4) row display none. In hence, it makes the display pixels in the (4n+1) row displaying the left-eye image signal  331  and the display pixels in the (4n+3) row displaying the right-eye image signal  332  being separated by the display pixels displaying none, which prevents from crosstalk between the left-eye image signal  331  and the right-eye image signal  332 , and it improves the display effect of the liquid crystal display panel thus. 
         [0046]    In the preferred embodiment, it also allows that display pixels in the (4n+1) row and in the (4n+3) row display none, display pixels in the (4n+2) row and in the (4n+4) row respectively display the left-eye image signal  331  and the right-eye image signal  332 . It is the same way to improve the display quality of the liquid crystal display panel. 
         [0047]    The FPR liquid crystal display panel for 3D display prevents from crosstalk between a left-eye image signal and a right-eye image signal by inputting black image signals to partial pixels. 
         [0048]    Please refer to  FIGS. 4A and 4B ,  FIG. 4A  is a timing diagram of driving signals in odd frames according to a second preferred embodiment of the present invention, and  FIG. 4B  is a timing diagram of driving signals in even frames according to the second preferred embodiment of the present invention. In the preferred embodiment, the liquid crystal display panel stops inputting the data signals  43  to the second display pixels through the scan signals  41  and inputs the left-eye image signal  431  to the first display pixels in odd frames and the right-eye image signal  432  to the first display pixels in even frames, or the liquid crystal display panel inputs the right-eye image signal  432  to the first display pixels in odd frames and the left-eye image signal  431  to the first display pixels in even frames when displaying signal images through the first display pixels. 
         [0049]    The liquid crystal display panel stops inputting the data signals  43  to the first display pixels through the scan signals  41  and inputs the left-eye image signal  431  to the second display pixels in odd frames and the right-eye image signal  432  to the second display pixels in even frames, or the liquid crystal display panel inputs the right-eye image signal  432  to the second display pixels in even frames and the left-eye image signal  431  to the second display pixels in odd frames when displaying signal images through the second display pixels. 
         [0050]    As  FIGS. 4A and 4B  show, the scan signals  41  are triggered by the CKV signal  45 , each of the scan signals  41  controls one row of display pixels to turn on or off, the data signals  43  are triggered by the TP signal  46 , each of the data signals  43  controls signal images in one column of display pixels. When the liquid crystal display panel of the preferred embodiment works, the scan signals  41  turn correspondent display pixels on, and in odd frames (as shown in  FIG. 4A ), the scan signals  41  turn all display pixels in odd rows on in order and all display pixels in even rows off while inputting the left-eye image signal  431 . In even frames (as shown in  FIG. 4B ), the scan signals  41  turn all display pixels in odd rows on in order and all display pixels in even rows off while inputting the right-eye image signal  432 . Therefore, in the end, the odd frames of the liquid crystal display panel only display left-eye images, the even frames of the liquid crystal display panel only display right-eye images, and image signals in each frame are separated by the display pixels displaying none. It prevents from crosstalk between image signals because left-eye images and right-eye images are displayed by different frames. 
         [0051]    Besides that, it also allows that it inputs the right-eye image signal  432  to the second display pixels in even frames and stops inputting data signals to the first display pixels if it inputs the left-eye image signal  431  to the first display pixels in odd frames and stops inputting data signals to the second display pixels. Therefore, it is also under protection of the preferred embodiment that display of the left-eye and the right-eye images by separating frames and dividing display pixels. 
         [0052]    The FPR liquid crystal display panel for 3D display of the preferred embodiment prevents from crosstalk between the left-eye and right-eye image signals by displaying separated frames. 
         [0053]    Please refer to  FIG. 5 ,  FIG. 5  is a timing diagram of driving signals applied on the liquid crystal display panel according to a third preferred embodiment of the present invention. In the preferred embodiment, the liquid crystal display panel displays black images through the second display pixels and alternatively inputs the left-eye image signal  531  and the right-eye image signal  532  to the first display pixels in the same frame when displaying signal images through the first display pixels. The liquid crystal display panel displays black images through the first display pixels and alternatively inputs the left-eye image signal  531  and the right-eye image signal  532  to the second display pixels in the same frame when displaying signal images through the second display pixels. As  FIG. 5  shows, the scan signals  51  are triggered by the CKV signal  55 , each of the scan signals  51  controls one row of display pixels to turn on or off, the data signals  53  are triggered by the TP signal  56 , each of the data signals  53  controls signal images in one column of display pixels. When the liquid crystal display panel of the preferred embodiment works, the scan signals  51  turn correspondent display pixels on, and in the same frame, the scan signals  51  turn all display pixels in order while inputting the left-eye image signal  531 , the black image signal  533 , the right-eye image signal  532  and the black image signal  533  alternatively, which means it inputs the left-eye signal  531  and the right-eye signal  532  alternatively to the first display pixels (i.e. the display pixels in odd rows) while inputting only the black image signal  533  to the second display pixels (i.e. the display pixels in even rows). Therefore, in the end, the display pixels in the first row of the liquid crystal display panel display the left-eye image signal  531 , those in the second row display the black image signal  533 , those in the third row display the right-eye image signal  532 , those in the fourth row display the black image signal  533 , in the (4n+1) row display the left-eye image signal  531 , those in the (4n+2) row display the black image signal  533 , those in the (4n+3) row display the right-eye image signal  532 , and those in the (4n+4) row display the black image signal  533 . In hence, it makes the display pixels in the (4n+1) row displaying the left-eye image signal  531  and the display pixels in the (4n+3) row displaying the right-eye image signal  532  being separated by the display pixels displaying none, which prevents from crosstalk between the left-eye image signal  531  and the right-eye image signal  532 , and it improves the display effect of the liquid crystal display panel thus. 
         [0054]    In the preferred embodiment, it also allows that display pixels in the (4n+1) row and in the (4n+3) row display the black image signal  533 , display pixels in the (4n+2) row and in the (4n+4) row respectively display the left-eye image signal  531  and the right-eye image signal  532 . It is the same way to improve the display quality of the liquid crystal display panel. 
         [0055]    The FPR liquid crystal display panel for 3D display of the embodiment prevents from crosstalk between a left-eye image signal and a right-eye image signal by inputting black image signals to partial pixels. 
         [0056]    Please refer to  FIGS. 6A and 6B ,  FIG. 6A  is a timing diagram of driving signals when showing odd frames according to a fourth preferred embodiment of the present invention, and  FIG. 6B  is a timing diagram of driving signals when showing even frames according to the fourth preferred embodiment of the present invention. In the preferred embodiment, the liquid crystal display panel displays black images through the second display pixels, inputs the left-eye image signal  631  to the first display pixels in odd frames and the right-eye image signal  632  to the first display pixels in even frames, or the liquid crystal display panel inputs the right-eye image signal  632  to the first display pixels in odd frames and the left-eye image signal  631  to the first display pixels in even frames when displaying signal images through the first display pixels. 
         [0057]    The liquid crystal display panel displays black images through the second display pixels, inputs the left-eye image signal  631  to the second display pixels in odd frames and the right-eye image signal  632  to the second display pixels in even frames, or the liquid crystal display panel inputs the left-eye image signal  631  to the second display pixels in even frames and the right-eye image signal  632  to the second display pixels in odd frames when displaying signal images through the second display pixel. As  FIGS. 6A and 6B  show, the scan signals  61  are triggered by the CKV signal  65 , each of the scan signals  61  controls one row of display pixels to turn on or off, the data signals  63  are triggered by the TP signal  66 , each of the data signals  63  controls signal images in one column of display pixels. When the liquid crystal display panel of the preferred embodiment works, the scan signals  61  turn correspondent display pixels on, and in odd frames (as shown in  FIG. 6A ), the scan signals  61  turn all display pixels on in order while inputting the left-eye image signal  631  and the black image signal  633  alternatively to the turn-on display pixels. In even frames (as shown in  FIG. 6B ), the scan signals  61  turn all display pixels on in order while inputting the right-eye image signal  632  and the black image signal  633  alternatively to the turn-on display pixels, which means it inputs the right-eye image signal  632  to the first display pixels (the display pixels in odd rows) and only inputs the black image signal  633  to the second display pixels (the display pixels in even rows). Therefore, in the end, the odd frames of the liquid crystal display panel only display left-eye images, the even frames of the liquid crystal display panel only display right-eye images, and image signals in each frame are separated by the display pixels displaying black images. It prevents from crosstalk between image signals because left-eye images and right-eye images are displayed by different frames. 
         [0058]    Besides that, it also allows that it inputs the left-eye image signal  632  to the second display pixels and inputs the black image signal  633  to the first display pixels in even frames if it inputs the left-eye image signal  631  to the first display pixels and inputs the black image signal  633  to the second display pixels in odd frames. Therefore, it is also under protection of the preferred embodiment that display of the left-eye and the right-eye images by separating frames and dividing display pixels. 
         [0059]    The FPR liquid crystal display panel for 3D display of the preferred embodiment based on the third preferred embodiment prevents from crosstalk between the left-eye and right-eye image signals by separating frames. 
         [0060]    The present invention further provides a liquid crystal display device using the above-mentioned liquid crystal display panel. The operating principle of the liquid crystal display panel is identical to that of the above-mentioned liquid crystal display panel of the preferred embodiment, and the detail is demonstrated in the relative description of the above-mentioned liquid crystal display panel of the preferred embodiment. 
         [0061]    In sum, the FPR liquid crystal display panel and the liquid crystal display device for 3D display in the present invention prevent from crosstalk between the left-eye signal image and the right-eye signal image by inputting a black image signal to partial pixels so that it solves a serious technical problem of mutual crosstalk between left-eye signal images and right-eye images of the liquid crystal display panel and the FPR liquid crystal display device for 3D display in the prior art. 
         [0062]    While the present invention has been described in connection with what is considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements made without departing from the scope of the broadest interpretation of the appended claims.
