In this embodiment, be that per two image sections are defined as a group, in the image section of each group, insert a replacement data RST then.Because in a time section T cycle, become and to have three data by originally only having two data, and be the back that replacement data RST is placed on the image section of each group, therefore aforesaid computing unit 301 just must concern the placement location that produces replacement data RST according to such counting.In addition, owing to signal of video signal DATA2 gets through data recombination, so signal of video signal DATA2 can import signal of video signal DATA1 naturally and postpones the Tdelay time.After obtaining signal of video signal DATA2, the signal kenel of the output enable signal that next just needs suitably to control each scanning element and received, so that the data time sequence according to signal of video signal DATA2 correctly drives corresponding scanning line, and then allow pixel energy receive correct loading data.That is to say, present kenel OED at the output enable signal, and when presenting electronegative potential (shown in T1), when video data will be loaded on respective pixel exactly, and present kenel OEB at the output enable signal, and when presenting electronegative potential (shown in T2), be exactly will be with the replacement data load time to respective pixel.
Fig. 6 is the sequential chart of the part signal of Fig. 4 circuit, and it illustrates the sequential of grid impulse signal of output enable signal (OED and OEB), the initial drive signal STV of grid and each bar sweep trace of gate clock signal CPV, two kinds of kenels.Wherein, the initial drive signal STV of grid has two kinds of initial waveforms, represents with STVD and STVB respectively.Please be simultaneously with reference to Fig. 4 and Fig. 6, so that more detailed explanation is done in the operation of Fig. 4 circuit.When time schedule controller 303 transmits initial waveform STVD to scanning element 53, and the output enable signal OE1 of OED kenel provided to scanning element 53, and when providing the output enable signal OE3 of OEB kenel to scanning element 55, just make scanning element 53 beginnings according to the output enable signal OE1 of initial waveform STVD, gate clock signal CPV and OED kenel and move.
Along with the transmission of initial waveform STVD in scanning element 53, scanning element 53 drives the first group's corresponding scanning beam of DATA2 in the signal of video signal in the mode that is divided into 2 times, and drives the sweep traces of adjacent two row at every turn.That is to say, be that scanning element 53 can drive two sweep traces simultaneously when hanging down logic current potential (low) at the output enable signal OE1 of OED kenel.With this example, scanning element 53 is the line of driven sweep simultaneously G53 earlier

4The time, source electrode driver 402 can corresponding output scanning line G54
3The video data of the pixel that is coupled, and source electrode driver 403 can corresponding output scanning line G54
4The video data of the pixel that is coupled.Promote, when driving adjacent two column scan lines, source electrode driver 402 can corresponding output be driven the video data of the pixel that the i column scan line in the sweep trace coupled, and source electrode driver 403 can corresponding output be driven the video data of the pixel that the i+1 column scan line in the sweep trace coupled.
Then, time schedule controller 303 transmits initial waveform STVB to scanning element 53.That is to say that time schedule controller 303 is exported initial waveform STVB after initial waveform STVD one given time of output.Simultaneously, time schedule controller 303 provides the output enable signal OE3 of OED kenel to scanning element 55, and the output enable signal OE1 of OEB kenel is provided to scanning element 53, and initial subsequently waveform STVD also is passed to scanning element 55.Therefore, scanning element 53 just begins to move according to the output enable signal OE1 of initial waveform STVB, gate clock signal CPV and OEB kenel, and scanning element 55 also begins to move according to the output enable signal OE3 of initial waveform STVD, gate clock signal CPV and OED kenel.Certainly, above-mentioned given time is to do setting according to actual needs, is not to be restriction with this embodiment.
Owing to, all be to present low logic current potential at it just can allow sweep trace to be enabled no matter be the OED kenel or the output enable signal of OEB kenel.Therefore, drive the 3rd corresponding scanning beam (G55 of group in the signal of video signal according to the output enable signal OE3 of initial waveform STVD, gate clock signal CPV and OED kenel in scanning element 55

4) time, because the output enable signal OE1 of OEB kenel presents high logic current potential (high), therefore this moment, scanning element 53 can not drive the sweep trace that it couples, and do not transmit in scanning element 54 and 56 because also have any initial waveform this moment, so scanning element 54 and 56 can not drive the sweep trace that it couples yet.
When scanning element 55 drives the sweep trace that it coupled, source electrode driver 402 can corresponding output be driven the video data of the pixel that the i column scan line in the sweep trace coupled, and source electrode driver 403 can corresponding output be driven the video data of the pixel that the i+1 column scan line in the sweep trace coupled.Then, the output enable signal OE3 of OED kenel presents high logic current potential, and the output enable signal OE1 of OEB kenel presents low logic current potential.Therefore, scanning element 53 is convenient for this section period driven sweep simultaneously line G53
