To adopt crystal grain-glass bond (Chip On Glass, COG) technology, and adopting indium tin oxide is example as the transparency conducting layer on glass substrate (not illustrating), and sweep trace S1～S4 and data line D1～D4 on display panel 130 carry out construction by indium tin oxide.And, because in the position relationship of display panel 130 and gate driver circuit 122 and source electrode drive circuit 124, sweep trace S1～S4 can be not identical with live width and the length of data line D1～D4.Also therefore, can produce the not identical phenomenon of resistance value had between not identical sweep trace S1～S4 and not identical data line D1～D4.
In the present embodiment, the deviser can be by the sweep trace S1～S4 on detection display panel 130 and the resistance value on data line D1～D4, and the signal that comes corresponding setting to be stored in memory cell 140 is adjusted data SMD.And adjust data SMD by signal and order about gate driver circuit 122 and produce scanning drive signal SDS1 with different electrical specifications～SDS4 to be sent to sweep trace S1～S4, and order about source electrode drive circuit 124 and produce data drive signal DDS1 with different electrical specifications～DDS4 to be sent to data line D1～D4.At this, the present embodiment can be adjusted at least electrical specification of one of them of driving activation time, driving voltage value and the drive current of scanning drive signal SDS1～SDS4, and adjust the gamma driving voltage value of data drive signal DDS1～DDS4 and drive the activation time at least one of them comes compensated scanning line S1～S4 and the upper reduction phenomenon because of inhomogeneous the caused demonstration usefulness of resistance value of data line D1～D4.
Below please refer to Fig. 1 and Fig. 2 A ~ Fig. 2 D, wherein, Fig. 2 A ~ Fig. 2 D illustrates respectively the schematic diagram of the adjustment waveform of the scanning drive signal SDS1 of the embodiment of the present invention～SDS4.In Fig. 2 A, scanning drive signal SDS1 wherein and SDS3 at it during scanning activation under respectively driving voltage when SEN1 and SEN3 equal turntable driving voltage VGH1, and scanning drive signal SDS2 and SDS4 at it during scanning activation under respectively driving voltage when SEN2 and SEN4 equal turntable driving voltage VGH2, wherein, turntable driving voltage VGH1 not identical with turntable driving voltage VGH2 (for example: turntable driving voltage VGH1 is higher than turntable driving voltage VGH2).In addition, scanning drive signal SDS1 and SDS3 at it during scanning activation under respectively the driving voltage of the time interval outside SEN1 and SEN3 equal turntable driving voltage VGL1, scanning drive signal SDS2 and SDS4 at it during scanning activation under respectively the driving voltage of the time interval outside SEN2 and SEN4 equal turntable driving voltage VGL2, wherein, turntable driving voltage VGL1 and turntable driving voltage VGL2 also can not identical (for example: turntable driving voltage VGL1 be lower than turntable driving voltage VGL2).
That is to say, continue above-mentioned example, when during correspondence receives the scanning activation, the resistance value of the sweep trace S1 of SEN1 and SEN3 and S3 is large with respect to the resistance value of other sweep trace (sweep trace S2 and S4), can be by the driving voltage that provides when SEN1 and SEN3 respectively relatively high turntable driving voltage VGH1 to using as scanning drive signal SDS1 and SDS3 during the scanning activation.Relatively, for sweep trace S2 and S4 with relative low impedance value, can during the scanning activation under respectively, in SEN2 and SEN4, provide the turntable driving voltage VGH2 that scanning drive signal SDS2 and SDS4 are relatively low to using as driving voltage at it.
In Fig. 2 B, during SEN1 during the scanning activation of scanning drive signal SDS1 wherein～SDS4 under respectively～SEN4, the current driving ability that is pulled up to turntable driving voltage VGH1 be endowed can be not identical.With present embodiment, during the scanning activation of scanning drive signal SDS1～SDS4 under respectively in SEN1～SEN4, it is not identical that scanning drive signal SDS1～SDS4 is pulled up to the needed time of turntable driving voltage VGH1, wherein, be pulled up to sooner the scanning drive signal that equals turntable driving voltage VGH1, its current driving ability be endowed is higher.
