In this, Fig. 5 that is disclosed in first embodiment and the drive waveforms figure of Fig. 6 can be used for driving display panel 701 equally.In this second embodiment, when the drive waveforms figure that utilizes Fig. 5 drives display panel 701, since in the display panel 701 each indigo plant (B) pixels be in the number of times that is subjected to the influence of corresponding sweep signal forbidden energy after the hold mode be three times, each green (G) pixel to be in the number of times that is subjected to the influence of corresponding sweep signal forbidden energy after the hold mode be twice, and the number of times that each red (R) pixel is in the influence that is subjected to corresponding sweep signal forbidden energy after the hold mode is for once.In this, for convenience of explanation, the spy indicates a numeral in each red (R), green (G) and blue (B) pixel in Fig. 8, and this numeral represents that promptly each red (R) in the display panel 701, green (G) and indigo plant (B) pixel are subjected to presenting the number of times of the influence of wearing effect.
Hence one can see that, and the number of times that the same color pixel is subjected to presenting the influence of wearing effect is all identical.Also also because of like this, the number of times that is subjected to presenting the influence of wearing effect owing to the same color pixel is all identical, so the brightness meeting of the image frame that display panel 701 is presented is even relatively, thereby improves the shortcoming that prior art is addressed.In addition, when the drive waveforms figure that utilizes Fig. 6 drives display panel 701, because to be in the number of times of the influence that is subjected to corresponding sweep signal forbidden energy after the hold mode identical in fact for all pixels in the display panel 701, the image frame that so can avoid display panel 701 to be presented produces colour cast.
In sum, because being three minutes one source pole, the array of pixels structure of the display panel of LCD proposed by the invention drives (0TSD) framework, so can cause the driving number of channel of source electrode driver can also be still less for semi-source pole driving architecture.More accurate, the driving number of channel of source electrode driver can lack three minutes two.In addition, though the array of pixels structure of the display panel of LCD proposed by the invention is the OTSD framework, but drive the words (being the drive waveforms figure that Fig. 5 and Fig. 6 illustrate) of display panel by the two kinds of different driving modes of arranging in pairs or groups, it is identical in fact then can to cause same color pixel in the display panel or all pixels to be subjected to presenting the number of times of the influence of wearing effect, thereby improve the shortcoming that prior art is addressed, and the image frame that more can avoid display panel to present produces colour cast.
Though the present invention discloses as above with embodiment; right its is not in order to limit the present invention; have in the technical field under any and know the knowledgeable usually; without departing from the spirit and scope of the present invention; when doing a little change and retouching, so protection scope of the present invention is as the criterion when looking accompanying the claim person of defining.
