Embodiment
Fig. 5 illustrates the source electrode driving device schematic diagram in order to drive display panel of one embodiment of the invention.Fig. 6 illustrates the flow chart of steps of the driving method of the display panel of one embodiment of the invention.Please refer to Fig. 5 and Fig. 6, the source electrode driving device 100 of the present embodiment is in order to drive display panel 200.Source electrode driving device 100 comprises data operation circuit 110 and pixel-driving circuit 120.Pixel-driving circuit 120 is coupled to data operation circuit 110.Data operation circuit 110 in order to receive pixel data Sp1 (step S200), and carries out a polarity decision computing, to determine the polarity distributed intelligence Sp2 (step S210) of the multiple pixels 210 on display panel 200 to pixel data Sp.In the present embodiment, polarity determines that the mode of computing is such as, in same driving passage, the grey decision-making of pixel data of rear a line (line) and the grey decision-making of the pixel data of previous row are subtracted each other the polarity deciding the pixel being positioned at rear a line.Then, pixel-driving circuit 120 drives display panel 200 (step S220) according to pixel data Sp1 and polarity distributed intelligence Sp2 again.It should be noted, in the present embodiment, for the purpose of brief description, Fig. 5 only illustrate 4 row pixels on display panel 200 and 12 drive passages to illustrate, only have in art and usually know that the knowledgeable is when know that the polarity distribution scenario of its quantity and pixel is not in order to limit the present invention.
Therefore, in the present embodiment, the polarity distribution scenario of the multiple pixels 210 on display panel 200 be by the data operation circuit 110 of source electrode driving device 100 according to the actual display frame of wanting of display panel 200, dynamically come to be determined.That is, source electrode driving device 100 dynamic adjusts each pixel size to the coupling effect that common electrode voltage produces when discharge and recharge, to reduce the skew of common electrode voltage, thus therefore the caused picture of improvement shows bad situation, to provide good display quality.
Specifically, Fig. 7 illustrates the polarity distribution scenario of multiple pixels of the some reversion relevant routine display panel 300 of the present invention one presenting change type, and Fig. 8 illustrates in Fig. 7 in order to drive the waveform schematic diagram of the driving voltage respectively driving passage to export during the second row pixel.Please refer to Fig. 7 and Fig. 8, on the display panel 300 of Fig. 7, the polarity distribution scenario of pixel is identical with Fig. 3, and be all the distribution scenario presenting level 2 reversion, only both display patterns are not identical.In figure 3, the row pixel (column pixels) that the display pattern of display panel 20 drives for driving passage R1, B1, G2, R3, B3, G4 shows the brightest GTG that grey decision-making is 255, the row pixel display grey decision-making driving passage G1, R2, B2, G3, R4, B4 to drive is the most dull gray rank of 0, and the display pattern defining display panel 20 is herein the second display pattern.In the figure 7, the row pixel display grey decision-making that the display pattern of display panel 300 drives for driving passage R1, G2, B3 is the brightest GTG of 255, the row pixel display grey decision-making driving passage G1, B1, R2, B2, R3, G3, R4, G4, B4 to drive is the most dull gray rank of 0, and the display pattern defining display panel 300 is herein the second display pattern.From the waveform of the driving voltage of Fig. 8, each driving voltage driving passage to export, the effect of its overall sum total will cause common electrode voltage Vcom upwards to offset.Therefore, for the second display pattern, the mode utilizing level 2 to reverse is to drive display panel 300, and common electrode voltage Vcom still can upwards offset, and effectively cannot improve picture and show bad situation.
The polarity distribution scenario of multiple pixels that the display panel 400 that Fig. 9 illustrates one embodiment of the invention drives with the reversion of adaptability point, Figure 10 illustrates in Fig. 9 in order to drive the waveform schematic diagram of the driving voltage respectively driving passage to export during the second row pixel.Please refer to Fig. 9 and Figure 10, in fig .9, the pattern shown by display panel 400 is identical with display panel 300, is all the second display pattern.In the present embodiment, on display panel 400, the distribution scenario of pixel polarity is such as show pattern by the data operation circuit 110 of Fig. 5 according to second, dynamically comes to be determined.Further, pixel-driving circuit 120 drives display panel 400 according to determined polarity distributed intelligence Sp2 again.Therefore the polarity distribution scenario of its pixel as shown in Figure 9, is to be reversed to basis with level 2, and the polarity distribution of the row pixel only driving passage G2, B2 to drive has carried out adaptive dynamic conditioning according to the second display pattern.Therefore the waveform of driving voltage from Figure 10, when discharge and recharge, each pixel can cancel each other to the coupling effect that common electrode voltage Vcom causes, and therefore common electrode voltage Vcom can not offset, thus improves picture and show bad situation.
Generally speaking, the type of drive of common reversal of poles, except above-mentioned some reversion and level 2 reversion, even comprise the type of drive of single line reversion (1-line inversion).The driving method of display panel of the present invention is equally also applicable to the polarity distribution scenario of dynamic conditioning panel pixel single line reversion.
The polarity distribution scenario of multiple pixels that the display panel 500 that Figure 11 illustrates another embodiment of the present invention drives with the reversion of adaptability single line, Figure 12 illustrates in Figure 11 in order to drive the waveform schematic diagram of the driving voltage respectively driving passage to export during the second row pixel.Please refer to Figure 11 and Figure 12, show the second display pattern equally for display panel 500, data operation circuit 110 can carry out polarity to pixel data Sp and determine computing, to determine the polarity distributed intelligence Sp2 of the multiple pixels 510 on display panel 500.Then, pixel-driving circuit 120 drives display panel 500 according to pixel data Sp1 and polarity distributed intelligence Sp2 again.Therefore the pixel polarity distribution scenario on display panel 500 as shown in figure 11, is be reversed to basis with single line, and the polarity distribution of the row pixel only driving passage R1, G2, B3 to drive has carried out adaptive adjustment according to the second display pattern to display.
Under the 3rd display pattern of an any random picture is described, under the type of drive of different reversal of poles, on the impact that common electrode voltage Vcom offsets, and the driving method applying display panel of the present invention is by this impact of reduction.
The polarity distribution scenario of multiple pixel on the display panel 600,700 that Figure 13 and Figure 15 illustrates pairwise correlation example of the present invention respectively, Figure 14 and Figure 16 illustrates in Figure 13 and Figure 15 respectively in order to drive the waveform schematic diagram of the driving voltage respectively driving passage to export during the second row pixel.Please refer to Figure 13 to Figure 16, display panel 600 drives with a reversion, and display panel 600 drives with level 2 reversions.In this two example, display panel 600,700 is when display the 3rd shows pattern, each pixel all can produce coupling effect to common electrode voltage Vcom when discharge and recharge, its result will make common electrode voltage Vcom produce suitable skew, respectively as shown in Figure 14 and Figure 16, wherein the degree that upwards offsets of the common electrode voltage Vcom of display panel 600 is large compared with display panel.
The polarity distribution scenario of multiple pixels that the display panel 800 that Figure 17 illustrates another embodiment of the present invention drives with adaptability reversal of poles, Figure 18 illustrates in Figure 17 in order to drive the waveform schematic diagram of the driving voltage respectively driving passage to export during the second row pixel.Please refer to Figure 17 and Figure 18, in fig. 17, the pattern shown by display panel 800 and display panel 600,700 identical, be all the 3rd display pattern.In the present embodiment, on display panel 800, the distribution scenario of pixel polarity is such as show pattern by the data operation circuit 110 of Fig. 5 according to the random the 3rd, dynamically comes to be determined.Further, pixel-driving circuit 120 drives display panel 800 according to determined polarity distributed intelligence Sp2 again.Therefore the polarity distribution scenario of its pixel as shown in figure 17, and on display panel 800, the polarity distribution of each pixel has carried out adaptive dynamic conditioning according to the 3rd display pattern.Therefore the waveform of driving voltage from Figure 18, when discharge and recharge, each pixel can cancel each other to the coupling effect that common electrode voltage Vcom causes, and can reduce the degree that common electrode voltage Vcom offsets, thus improves picture and show bad situation.
Referring again to Fig. 5 and Fig. 6.In this exemplary embodiment, data operation circuit 110 is such as sequentially carry out polarity to the pixel data of the entire row of pixels of each row pixel to determine computing, to determine the polarity distributed intelligence of multiple pixel 210 on display panel 200.For example, the data operation circuit 110 of the present embodiment first can carry out polarity decision computing, to determine the polarity distribution scenario of the first row entire row of pixels to the pixel data of the first row pixel full line.Then, the data operation circuit 110 of the present embodiment carries out polarity decision computing, to determine the polarity distribution scenario of the second row entire row of pixels to the pixel data of the second row pixel full line again.Afterwards, data operation circuit 110 can follow this rule, successively carries out polarity to the pixel data of the full line of next line and determines computing, thus determine the polarity distributed intelligence of all pixels on display panel 200.
In the present invention, data operation circuit 110 also sequentially can carry out polarity to the pixel data of at least part of pixel of each row pixel and determine computing, to determine the polarity distributed intelligence of at least part of pixel on display panel, is described as follows.
