Description
Technical field
The invention relates to a kind of driving method, and particularly relevant for a kind of driving method of display panel.
Background technology
For liquid crystal display panel of thin film transistor (thin-film transistor liquid crystal display, TFT-LCD), M * N sub-pixel (sub-pixel) need use M bar source electrode line and also have N bar gate line to control traditionally, and wherein M and N are all natural number.But existing at present a kind of new Driving technique, it reduces by half needed source electrode line number, and needed gate line number doubled, control panel with M * N sub-pixel, and adopt the panel of this new technology, be called half source electrode-times gate type panel (half-source-double-gate type panel).
Owing to more than the several times that general M is N, therefore adopt the advantage of this new technology, be the output pin figure place that can reduce the source driver chip of these source electrode lines of control in a large number, its chip area is reduced, and then reduce its manufacturing cost.In addition, this new technology also can reach the advantage that reduces DC current, can also increase the elasticity of panel layout (panel layout) simultaneously, for example chip is placed the left side or the right side of panel.
Yet this novel panel but still adopts the gate line of old profile plate to drive sequential, causes can producing the phenomenon of vertical light and shade line when showing same GTG (gray level), thereby makes picture quality descend.Below respectively to adopt the novel panel of line counter-rotating (line inversion) technology and AC system common electric potential, and adopt the novel panel of some counter-rotating (dot inversion) technology and single flow common electric potential to illustrate, and suppose that cited novel panel all adopts normality to deceive the picture display mode.
Fig. 1 is the synoptic diagram of the half source electrode-times gate type panel of employing line inversion technique.Panel among this figure also adopts the AC system common electric potential, and it has N bar sweep trace, M/2 bar source electrode line and 2N bar gate line, represents with L1～L (N), S1～S (M/2) and G1～G (2N) respectively.All have M sub-pixel (sub-pixel) 101 in each sweep trace, and in same sweep trace, the shown color of adjacent sub-pixel 101 is different, wherein R represents to show the sub-pixel 101 of red primaries, G represents to show the sub-pixel 101 of green primary color, and B represents to show the sub-pixel 101 of blue primary.
Fig. 2 is each signal timing diagram of the described panel of Fig. 1.VCOM among this figure represents common electric potential, indicates the sign that then all corresponds among Fig. 1 as for remaining.By learning among the figure, gate lines G 1～the G (2N) of this panel drives one by one in incremental mode, just adopt old gate line to drive sequential, and the while is according to the opening sequence of gate line, in the extremely corresponding sub-pixel of source electrode line loading picture data.For example, as driving grid line G1, and then open when being coupled to the sub-pixel 101 of gate lines G 1, source electrode line S1～S (M/2) just transmits the required picture data of sub-pixel that is unlocked accordingly; And as driving grid line G2, and then open when being coupled to the sub-pixel 101 of gate lines G 2, source electrode line S1～S (M/2) just transmits the required picture data of sub-pixel that is unlocked accordingly.
Yet, owing to adopt the relation of line inversion technique, during gate line in driving same sweep trace, exchange common electric potential and can present same polarity, as shown in Figure 3.Fig. 3 is the common electric potential of each sweep trace of Fig. 2 and the change in polarity key diagram of each source electrode line.Please refer to Fig. 3, is example with sweep trace L1, because when driving grid line G1, therefore the just firm reverse of common electric potential VCOM just can reach stationary value after after a while, and when driving grid line G2, owing to do not need reverse, so common electric potential remains the stationary value of same polarity.Hence one can see that, the idiostatic together pressure reduction of picture signal when driving grid line G1, the idiostatic together pressure reduction of picture signal when understanding less than driving grid line G2 is so the brightness of the sub-pixel of being opened less than gate lines G 2 is understood in the brightness of the sub-pixel that gate lines G 1 is opened.Certainly, in point of fact, when driving grid line G1, common electric potential VCOM is not a waveform and changing as shown in Figure 3 necessarily, but generally speaking, the idiostatic together pressure reduction of picture signal when driving grid line G1, and the idiostatic together pressure reduction of picture signal when driving grid line G2, the value of the two is different.In like manner, same situation also can take place in sweep trace L2～L (N), so adopt old gate line to drive sequential, can cause the phenomenon that visually produces vertical light and shade line.
Fig. 4 is the synoptic diagram of the half source electrode-times gate type panel of employing point inversion technique.Panel among this figure also adopts the single flow common electric potential,, does not repeat them here as hardware structure shown in Figure 1 as for the hardware structure of this panel.For the convenience that illustrates, below only with source electrode line S1 and S2, also have gate lines G 1～G4 that old mode of operation is described, as shown in Figure 5.Fig. 5 is the key diagram of the sequential of the change in polarity of source electrode line S1, S2 of Fig. 4 and gate lines G 1～G4.N among this figure can be expressed as integer 0, perhaps is expressed as natural number.If N is 0, then 4N+1,4N+2,4N+3 and 4N+4 represent respectively during the 1st, the 2nd, the 3rd and the 4th picture; If N is 1, then 4N+1,4N+2,4N+3 and 4N+4 represent that respectively the rest may be inferred for all the other during the 5th, the 6th, the 7th and the 8th picture.As for gate lines G 1～G4 is to drive one by one in incremental mode, just adopts old gate line to drive sequential.
Can find that by Fig. 5 no matter during which picture, when driving grid line G2 and G4, source electrode line S1, S2 are just reverses, therefore this moment common electric potential VCOM accurate position can be affected.To be example during the 4N+1 picture, when driving grid line G2, the polarity of source electrode line S1, S2 is just just by just changeing negative, so the accurate position of the common electric potential on the liquid crystal panel can be pulled to negative polarity a little; And when driving grid line G4, the polarity of source electrode line S1, S2 has just just turned negative number to positive number, so the accurate position of the common electric potential on the liquid crystal face version can be pulled to positive polarity a little.Thus, source electrode line S1, S2 when driving grid line G2 and G4 and the pressure reduction of common electric potential VCOM, source electrode line S1, S2 when understanding and the pressure reduction of common electric potential VCOM less than driving grid line G1 and G3.In like manner, during the 4N+2 picture～same situation also can take place during the 4N+4 picture, so adopt old gate line to drive sequential, can cause the phenomenon that visually produces vertical light and shade line.

Suppose that half source electrode-times gate type panel adopts line inversion technique and AC system common electric potential, as shown in Figure 1.Solve one of method of vertical light and shade line phenomenon so, just as shown in Figure 6.Fig. 6 is the driving method according to the display panel of one embodiment of the invention, its enumerate sweep trace L1～L3 during the 4N+1 picture～the 4N+4 picture during the time, the polarity of common electric potential VCOM, and gate lines G 1～G6 during the 4N+1 picture～the 4N+4 picture during the time driving order.Wherein N can be expressed as integer 0, perhaps is expressed as natural number.If N is 0, then 4N+1,4N+2,4N+3 and 4N+4 represent respectively during the 1st, the 2nd, the 3rd and the 4th picture; If N is 1, then 4N+1,4N+2,4N+3 and 4N+4 represent that respectively the rest may be inferred for all the other during the 5th, the 6th, the 7th and the 8th picture.In addition, the sign VCOM among Fig. 6 represents common electric potential, as for other sign then all corresponding to the sign among Fig. 1.
In Fig. 6, in the time of during the 4N+1 picture and during the 4N+2 picture, gate lines G 1～G6 drives one by one in incremental mode, yet during the 4N+3 picture and during the 4N+4 picture time, just changes the driving order of the pairing gate line of same sweep trace.Therefore during the 4N+1 picture and in during the 4N+2 picture, the idiostatic together pressure reduction of picture signal when driving grid line G1, G3 and G5, the idiostatic together pressure reduction of picture signal when understanding less than driving grid line G2, G4 and G6, so the brightness of gate lines G 1, sub-pixel that G3 and G5 opened, can be less than the brightness of gate lines G 2, sub-pixel that G4 and G6 opened.
In like manner, during the 4N+3 picture and in during the 4N+4 picture, the idiostatic together pressure reduction of picture signal when driving grid line G2, G4 and G6, the idiostatic together pressure reduction of picture signal when understanding less than driving grid line G1, G3 and G5, so the brightness of gate lines G 2, sub-pixel that G4 and G6 opened, can be less than the brightness of gate lines G 1, sub-pixel that G3 and G5 opened.Therefore as can be known, this kind method of operating can be improved the inhomogeneous and vertical light and shade line phenomenon that causes of system of Himdu logic darkness.
Because the line inversion technique is not the polarity that every renewal one subframe just must change the common electric potential of same sweep trace, its also can be per two picture reversed polarities once.In this case, just available mode shown in Figure 7 solves vertical light and shade line phenomenon.Fig. 7 is the driving method according to the display panel of another embodiment of the present invention, its enumerate equally sweep trace L1～L3 during the 4N+1 picture～the 4N+4 picture during the time, the polarity of common electric potential VCOM, and gate lines G 1～G6 during the 4N+1 picture～the 4N+4 picture during the time driving order.Sign VCOM among Fig. 7 represents common electric potential, as for other sign then all corresponding to the sign among Fig. 1.

In like manner, during the 4N+2 picture and in during the 4N+4 picture, the idiostatic together pressure reduction of picture signal when driving grid line G2, G4 and G6, the idiostatic together pressure reduction of picture signal when understanding less than driving grid line G1, G3 and G5, so the brightness of gate lines G 2, sub-pixel that G4 and G6 opened, can be less than the brightness of gate lines G 1, sub-pixel that G3 and G5 opened.Therefore as can be known, this kind method of operating can be improved the inhomogeneous and vertical light and shade line phenomenon that causes of system of Himdu logic darkness.
In the nature of things, in the middle of above-mentioned two embodiment, source electrode line S1～S3 is when transmitting picture signal accordingly according to the driving order of gate lines G 1～G6, to demonstrate normal picture.
What deserves to be mentioned is, during the 4N+1 picture of Fig. 6 and in during the 4N+3 picture, the polarity of the interchange common electric potential of same sweep trace is identical, and during the 4N+2 picture and in during the 4N+4 picture, the polarity of the interchange common electric potential of same sweep trace is also identical, but the polarity of this moment with during the 4N+1 picture, reach the 4N+3 picture during in polarity opposite.In addition, during the 4N+1 picture of Fig. 7 and in during the 4N+2 picture, the polarity of the interchange common electric potential of same sweep trace is identical, and during the 4N+3 picture and in during the 4N+4 picture, the polarity of the interchange common electric potential of same sweep trace is also identical, but the polarity of this moment with during the 4N+1 picture, reach the 4N+2 picture during in polarity opposite.Hold this principle, the user works as and can understand the rest by analogy according to above-mentioned teaching, and then uses the present invention in the line inversion technique of other each kenels.
Suppose that half source electrode-times gate type panel adopts some inversion technique and single flow common electric potential, as shown in Figure 4.Solve one of method of vertical light and shade line phenomenon so, just as shown in Figure 8.Fig. 8 is the driving method according to the display panel of yet another embodiment of the invention, its enumerate source electrode line S1 and S2 during the 4N+1 picture～the 4N+4 picture during the time polarity, and gate lines G 1～G4 during the 4N+1 picture～the 4N+4 picture during the time the driving order.In addition, the sign VCOM among Fig. 8 represents common electric potential, as for other sign then all corresponding to the sign among Fig. 4.
In Fig. 8, in the time of during the 4N+1 picture and during the 4N+2 picture, gate lines G 1～G4 drives one by one in incremental mode, yet during the 4N+3 picture and during the 4N+4 picture time, just changes the driving order of the pairing gate line of same sweep trace.Therefore in during the 4N+1 picture, reaching during the 4N+2 picture, source electrode line S1, S2 when driving grid line G2 and G4 and the pressure reduction of common electric potential VCOM, source electrode line S1, S2 when understanding and the pressure reduction of common electric potential VCOM less than driving grid line G1 and G3.In like manner, during the 4N+3 picture and in during the 4N+4 picture, source electrode line S1, S2 when driving grid line G1 and G3 and the pressure reduction of common electric potential VCOM, source electrode line S1, S2 when understanding and the pressure reduction of common electric potential VCOM less than driving grid line G2 and G4.Therefore as can be known, this kind method of operating can be improved the inhomogeneous and vertical light and shade line phenomenon that causes of system of Himdu logic darkness.
Because the some inversion technique also has multiple embodiment, be difficult to particularize, yet the user is when being used in the middle of other the some inversion technique according to the described spirit of Fig. 8.Below will enumerate several type of drive of the present invention again, and can more understand the present invention, as Fig. 9～shown in Figure 13 in the hope of the user.Fig. 9～Figure 13 all enumerate source electrode line S1 and S2 during the 4N+1 picture～the 4N+4 picture during the time polarity, and gate lines G 1～G4 during the 4N+1 picture～the 4N+4 picture during the time the driving order.In addition, the sign VCOM among Fig. 9～Figure 13 represents common electric potential, as for other sign then all corresponding to the sign among Fig. 4.Fig. 9～mode of operation shown in Figure 13 and mode of operation shown in Figure 8 are extremely similar, mainly be in four pictures of 4N+1 picture～4N+4 picture, change (or exchanging) source electrode line S1, S2 change in polarity order (need exchange variation) as long as meet liquid crystal two terminal voltages to the pressure reduction of common electric potential VCOM, collocation changes the driving order of gate lines G 1～G4 again, carry out the driving of display panel, so embodiment is as more than Fig. 8～Figure 13, the user just repeats no more at this when understanding the rest by analogy.
By the teaching of the various embodiments described above, roughly can summarize basic operation methods more of the present invention, as shown in figure 14.Figure 14 is the process flow diagram according to the driving method of the display panel of one embodiment of the invention.The method includes the following step, at first, during first picture in, drive earlier the first grid line, drive the second grid line again (as step a).Then, during second picture in, drive earlier the second grid line, drive first grid polar curve again (as step b).
Each embodiment of the above-mentioned employing line inversion technique of enumerating, careful, it all is the common electric potential reversed polarity when finishing a sweep trace that adopts AC system, come for example with Fig. 1 and Fig. 6, finish a sweep trace and must contain the time that drives two gate lines, yet the signal that is transmitted on the common electric potential of some half source electrode-times gate type panel and the source electrode line can promptly reverse once after finishing half bar sweep trace (driving the time of a gate line), the change in polarity of collocation common electric potential and some inversion technique or row (column) inversion technique that the gate line opening sequence can be reached another kind of pattern, even so, the technology of these variations also stands good in the present invention, shown in Figure 15～17.
For convenience of description, Figure 15～17 are example with the panel that adopts the black picture display mode of normality all.Please earlier with reference to Figure 15, Figure 15 lists under wherein a kind of embodiment of above-mentioned another pattern point inversion technique, use an example of the present invention, its illustrate source electrode line S1, S2 and common electric potential VCOM during the 4N+1 picture～the 4N+4 picture during the time polarity, and gate lines G 1～G4 during the 4N+1 picture～the 4N+4 picture during the time the driving order.Certainly, utilizing the source electrode line transmission signals of the common electric potential of AC system and AC system to reach an inversion technique is not to have only mode shown in Figure 15, therefore should not limit the present invention in mode shown in Figure 15.That is to say, during the 4N+1 picture shown in Figure 15～signal waveform during the 4N+4 picture, it is not absolute order according to 4N+1,4N+2,4N+3 and 4N+4, the user can exchange the order of these four pictures arbitrarily, as long as according to during the 4N+1 picture～the 4N+4 picture during in the signal waveform that illustrated operate, just the required polarity commutativity of liquid crystal display can be reached, the inhomogeneous and vertical light and shade line phenomenon that causes of system of Himdu logic darkness can be improved simultaneously.
