First embodiment

Please with reference to Fig. 3, it shows the process flow diagram according to the FRC driving method of the first embodiment of the present invention.In step S310, in first frame, time schedule controller 240 optionally trembles processing to these pixel datas D1～Dm according to first fundamental matrix, to produce many FRC data FRC1～FRCn.In step S320, data driver 260 exports a plurality of FRC positive polarity pixel voltage VP1～VPk according to these FRC data FRC1～FRCn and a plurality of FRC negative polarity pixel voltage VN1～VNk drives these pixels of part P1～Pm at least.

In step S330, in second frame, time schedule controller 240 optionally trembles processing to these pixel datas D1～Dm according to second fundamental matrix, to produce many FRC data FRC1 '～FRCn '.Then; In step S340, data driver 260 drives these pixels of part P1～Pm at least according to these FRC data FRC1 '～FRCn ' output a plurality of FRC positive polarity pixel voltage VP1 '～VPk ' and a plurality of FRC negative polarity pixel voltage VN1 '～VNk '.Second frame and first frame are adjacent.Above-mentioned first and second adjacent frame is for can show two frames of two pictures in regular turn.

In first embodiment, if will make display panel 220 in first and second frame, can avoid producing phenomenon of picture flicker, these pixels of the part at least P1～Pm that is then driven meets following condition.In first frame; The number of the first color sub-pixel of these pixels P1～Pm that is driven by these FRC positive polarity pixel voltages VP1～VPk is equal to the number by these FRC reverse voltages VN1～VNk institute first color sub-pixels driven in fact.And; In second frame; By the number of these FRC positive polarity pixel voltages VP1 '～VPk ' institute first color sub-pixels driven, be equal to number in fact by these FRC negative polarity pixel voltages VN1 '～VNk ' institute first color sub-pixels driven.Above-mentioned condition also is applicable to the second color sub-pixel of these pixels P1～Pm, so do not repeat at this.

Be example with the three primary colors sub-pixel now, and how calculate these numbers with first example and second example shows.

First frame :+RD ,+GD, and+BD is defined as red sub-pixel that these FRC positive polarity pixel voltages VP1～VPk drives, green sub-pixels, and the number of blue subpixels respectively;-RD ,-GD, and-BD is defined as red sub-pixel that these FRC negative polarity pixel voltages VN1～VNk drives, green sub-pixels, and the number of blue subpixels respectively.

Second frame :+RD ' ,+GD ', and+BD ' is defined as red sub-pixel that these FRC positive polarity pixel voltages VP1 '～VPk ' drives, green sub-pixels, and the number of blue subpixels respectively;-RD ' ,-GD ' ,-BD ' is defined as red sub-pixel that these FRC negative polarity pixel voltages VN1 '～VNk ' drives, green sub-pixels, and the number of blue subpixels respectively.

First example shows is following.Please with reference to Fig. 4 A and 4B, it shows these pixels P1～Pm of first embodiment of the invention respectively, first frame according to fundamental matrix M2, and in second frame according to fundamental matrix M2, with the synoptic diagram of the example that pixel voltage was driven that receives opposed polarity.

In Fig. 4 A and 4B, pixel P1～Pm for example comprises three primary colors sub-pixel R, G and the B that strip (stripe) is arranged.Data driver 260 is to carry out polar switching with the mode of 2 counter-rotatings (two-dotinversion), and wherein, point (dot) corresponds to sub-pixel.Fundamental matrix M1 and M2 for example are stored among the time schedule controller 240.Fundamental matrix M1 and M2 for example respectively have 4 * 4 points, and respectively comprise a plurality of vibration process points (space shown in oblique line) and a plurality of non-vibration process points (like the space of blank).The pixel data that sub-pixel received of corresponding vibration process points will be trembleed processing by time schedule controller 240, and on the contrary, the pixel data that sub-pixel received of corresponding non-vibration process points will can not trembleed processing by time schedule controller 240.

In first example, these process points of two fundamental matrix M1 and M2 are base unit (pixel-based) with the pixel, to correspond to these pixels P1～Pm.That is, in Fig. 4 A, the three primary colors sub-pixel of non-vibration process points A2 respective pixel P1, vibration process points A1 is the three primary colors sub-pixel of respective pixel P2 then.The old friend, in first frame, the pixel data that this three primary colors sub-pixel of pixel P1 is received will can not tremble processing, and the pixel data that this three primary colors sub-pixel of pixel P2 is received will tremble processing.And the fundamental matrix M1 with 4x4 point corresponds to 48 subpixels, shown in Fig. 4 A.Similarly, the corresponding relation of the fundamental matrix M2 of Fig. 4 B and pixel P1～Pm is also similar.

Shown in Fig. 4 A, in first frame, this 48 subpixels+the RD value is 4, and the value of-RD also is 4, and similarly ,+GD is all 4 with the value of-GD, and+BD also is all 4 with the value of-BD.Shown in Fig. 4 B, in second frame, this 48 subpixels+value of RD ' is 4, and the value of-RD ' also is 4, and similarly ,+GD ' is all 4 with the value of-GD ', and+BD ' also is all 4 with the value of-BD '.

Can know ground by inference, in first and second frame, the number of each color sub-pixel R, G and the B that is driven by FRC positive polarity pixel voltage will be same as the number of each the color sub-pixel R, G and the B that are driven by FRC negative polarity pixel voltage respectively.So, the phenomenon of flicker will be reduced.

Please be simultaneously with reference to Fig. 5 A and 5B.Fig. 5 A shows display device and is carrying out traditional FRC driving method, and the raw pixel data d0 homogeneous phase of all pixels simultaneously, an example of the oscillogram of the average voltage V0 of the pixel voltage that all pixels received.Indicate the square frame of " trembling ", the magnitude of voltage that the representative vibration is increased and decreased when handling.Fig. 5 B shows according to the first embodiment of the present invention and is carrying out the FRC driving method, and the raw pixel data d0 homogeneous phase of all pixels simultaneously, an example of the oscillogram of the average voltage V1 of the pixel voltage that all pixels received.In practical operation, the applicant finds that when pixel data being trembleed processing, if can let the average voltage of first frame and second frame close in fact, the phenomenon that can avoid glimmering takes place.

That is to say, in traditional FRC driving method of Fig. 5 A, if in the first frame F1, tremble processing the negative polarity pixel number and positive polarity pixel number as many, then average voltage V0 has an accurate L1 in the first frame F1.If in the second frame F2, the number of trembleing the negative polarity pixel of processing is less than the number of positive polarity pixel, and then average voltage V0 then has the accurate L2 in position in the second frame F2, and two accurate L1 and L2 differ a difference.And because average voltage corresponding to the mean flow rate of display frame, so the mean flow rate of the display frame of display panel 220 will change at this two frames F1 and F2 to some extent, and produces the phenomenon of glimmering.

Accordingly; In Fig. 5 B, the FRC driving method of the first embodiment of the present invention, tremble among the first frame F1 processing the negative polarity pixel number and positive polarity pixel number as many; And the negative polarity pixel of in the second frame F2, trembleing processing also with the number of positive polarity pixel as many; So average voltage V1 can have approaching in fact position standard at the first frame F1 and the second frame F2, for example both all have the accurate L1 in position, therefore; Display panel 220 will be identical in fact in the mean flow rate of the display frame that this two frame F1 and F2 are shown, and can avoid the phenomenon of glimmering.

Now that second example shows is following.What second example was different with first example is, each process points of two fundamental matrix M1 and M2 is elementary cell (dot-based) with the sub-pixel, to correspond to these pixels P1～Pm.Please with reference to Fig. 6 A and 6B; It shows these pixels P1～Pm of the first embodiment of the present invention respectively; In first frame according to fundamental matrix M1, and in second frame according to fundamental matrix M2, with the synoptic diagram of another example that pixel voltage was driven of receiving opposed polarity.

Shown in Fig. 6 A, in first frame, this 48 subpixels+value of RD is 4, and the value of-RD also is 4, and similarly ,+GD is all 4 with the value of-GD, and+BD also is all 4 with the value of-BD.Shown in Fig. 6 B, in second frame, this 48 subpixels+value of RD ' is 4, and the value of-RD ' also is 4, and similarly ,+GD ' is all 4 with the value of-GD ', and+BD ' also is all 4 with the value of-BD '.

Therefore, in second example, also can avoid phenomenon of picture flicker to take place effectively.

Second embodiment

What second embodiment was different with first embodiment is that if will make display panel 220 can show the effect with lightness stabilized picture, these pixels P1～Pm of part at least that is then driven meets the following stated condition.In first and second frame; Number by these FRC positive polarity pixel voltage VP1～VPk and VP1 '～VPk ' institute first color sub-pixels driven is essentially zero, or is essentially zero by the number of these FRC reverse voltage VN1～VNk and VN1 '～VNk ' institute first color sub-pixels driven.And above-mentioned condition also is applicable to the second color sub-pixel, so do not repeat at this.

Following with first example shows now.Please with reference to Fig. 7 A and 7B, it shows these pixels P1～Pm of second embodiment of the invention respectively, in first frame according to fundamental matrix M1, and in second frame according to basic square M2, with the synoptic diagram of the example that pixel voltage was driven that receives opposed polarity.Similar in Fig. 4 A and 4B, in Fig. 7 A and 7B, these process points of two fundamental matrix M1 and M2 are base unit with the pixel, to correspond to these pixels P1～Pm.

Shown in Fig. 7 A, in first frame, this 48 subpixels-value of GD is 0, shown in Fig. 7 B, and in second frame, this 48 subpixels-value of GD ' also is 0.Can know ground by inference, in first and second frame, the number of these green sub-pixels G that is driven by these FRC negative polarity pixel voltages is essentially zero.Substituting ground, these bluenesss that driven by these FRC negative polarity pixel voltages or the number of red sub-pixel B or R also are essentially zero.So, can reduce phenomenon of picture flicker effectively.

Please be simultaneously with reference to Fig. 5 C, it shows according to a second embodiment of the present invention and is carrying out the FRC driving method, and the raw pixel data d0 homogeneous phase of all pixels is simultaneously, an example of the oscillogram of the average voltage V2 of the pixel voltage that all pixels received.Because in the first frame F1 and the second frame F2, the number of the sub-pixel that these FRC negative polarity pixel voltages are driven is all zero in fact, therefore, in Fig. 5 C, can have approaching in fact position standard at the first frame F1 and the second frame F2 average voltage V2, like the accurate L2 in position.So the phenomenon that can avoid glimmering takes place.

Now that second example shows is following.In second example, different with first example is, each process points of two fundamental matrix M1 and M2 is elementary cell with the sub-pixel, to correspond to these pixels P1～Pm, shown in Fig. 8 A and 8B.Similarly, in second example, the number of these sub-pixels R, G and the B that is driven by these FRC negative polarity pixel voltages can be essentially zero.So, the phenomenon that also can avoid glimmering takes place.

In addition, the applicant has also disclosed other two fundamental matrix M3 and M4, and shown in Fig. 9 A and 9B, it can be applicable among second embodiment.In addition, it is the example explanation that second embodiment exports two pictures with display device 200 according to two fundamental matrixs, so also is not limited thereto.Time schedule controller 240 also can tremble processing according to four fundamental matrix M1～M4, to avoid film flicker.

In the described display device 200 of the above embodiment of the present invention.Display panel 220 is three primary colors sub-pixel R, G and the B with stripe-arrangement, and data driver 260 is to carry out polar switching with the mode of 2 counter-rotatings.Yet also be not limited thereto.As long as can utilize corresponding fundamental matrix, let display panel in adjacent frame, have close average voltage, take place with the phenomenon of avoiding glimmering, all in protection scope of the present invention.
