Embodiment
Please refer to Fig. 2, Fig. 2 is the schematic diagram of the embodiment of the present invention one display system 20.Display system 20 can be a thin film transistor (TFT) (Thin Film Transistor, TFT) liquid crystal display, and its detailed building form or framework look different application and different.For asking simple declaration, Fig. 2 only shows panel 200, gate drive apparatus 202 and a control module 204 of display system 20, and all the other elements being relevant to concept of the present invention as non-immediate such as housing, source electrode driving device, connecting interfaces then slightly do not show.Panel 200 comprises sweep trace SL1 ~ SLn, data line DL1 ~ DLm.Wherein, for the sake of clarity, sweep trace SL4 ~ SLn and data line DL4 ~ DLn does not illustrate in FIG.Each intersection of sweep trace SL1 ~ SLn and data line DL1 ~ DLm is respectively coupled to transistor MN, and transistor MN is coupled to electric capacity CS, CL.The operation principles of panel 200 should be known by those skilled in the art, for the sake of clarity, is not repeated herein.Gate drive apparatus 202 comprises grid electrode drive module GDM1 ~ GDMn, is used for producing gate drive signal Y1 ~ Yn, to drive sweep trace SL1 ~ SLn.Control module 204 is used for according to gate drive signal Y1 ~ Yn, adjust the resistance value of the output resistance of grid electrode drive module GDM1 ~ GDMn respectively, to lower the impact of the upper signal of data line DL1 ~ DLm for sweep trace SL1 ~ SLn, thus avoid display system 20 malfunction.
Specifically, grid electrode drive module GDM1 ~ GDMn comprises drive element of the grid GDU1 ~ GDUn and variable resistor RSW1 ~ RSWn.Drive element of the grid GDU1 ~ GDUn is respectively coupled to variable resistor RSW1 ~ RSWn, is used for producing gate drive signal Y1 ~ Yn, with sequentially activation sweep trace SL1 ~ SLn.When during gate drive apparatus 202 is for activation sweep trace SL1 ~ SLn during scan line SLa, in drive element of the grid GDU1 ~ GDUn, gate drive signal Ya can be adjusted to a noble potential VGH by a drive element of the grid GDUa, and remaining gate drive signal can be adjusted to an electronegative potential VGL by remaining drive element of the grid.Now, in order to allow drive element of the grid GDUa rapidly gate drive signal Ya is adjusted to noble potential VGH, the resistance value of the variable resistor RSWa being coupled to drive element of the grid GDUa can be adjusted to a resistance value R1(as the resistance value close to short circuit by control module 204).Now, in order to lower the impact of the signal on data line DL1 ~ DLm for electronegative potential VGL on remaining gate drive signal, the variable-resistance resistance value being coupled to all the other drive element of the grid can be adjusted to a resistance value R2(as the resistance value close to open circuit by control module 204).Subsequently, when gate drive apparatus 202 is for being changed into scan line SLb under activation by activation sweep trace SLa, because the current potential of gate drive signal Ya need be adjusted to electronegative potential VGL rapidly by noble potential VGH, the resistance value of variable resistor RSWa is maintained resistance value R1 by control module 204.In other words, control module 204 is when gate drive signal Ya is converted to noble potential VGH by electronegative potential VGL, the resistance value of the output resistance (i.e. variable resistor RSWa) producing the drive element of the grid GDUa of gate drive signal Ya is adjusted to resistance value R1, to improve the driving force of drive element of the grid GDUa, thus allow drive element of the grid GDUa can change gate drive signal Ya rapidly.Now, the resistance value that control module 204 also can adjust the output resistance being coupled to all the other drive element of the grid is adjusted to resistance value R2, to lower the impact of the signal on data line DL1 ~ DLm for gate drive apparatus 202.Should be noted, if now have a drive element of the grid GDUx namely to indicate for a gate drive signal Yx is converted to electronegative potential VGL(by noble potential VGH the sweep trace stopping activation gate drive signal Yx to drive), after the resistance value of the output resistance (i.e. variable resistor RSWx) being connected to drive element of the grid GDUx can be maintained resistance value R1 a period of time by control module 204, again the resistance value of the output resistance being connected to drive element of the grid GDUx is adjusted to resistance value R2, to guarantee that gate drive signal Yx promptly can be converted to electronegative potential VGL by noble potential VGH by drive element of the grid GDUx.Accordingly, control module 204 changes according to the current potential of gate drive signal Y1 ~ Yn, and the resistance value of adjustment variable resistor RSW1 ~ RSWn, to avoid display system 20 malfunction.
For the operation workflow of above-mentioned display system 20, illustrate as follows.Please refer to Fig. 3, Fig. 3 is the sequential chart of coherent signal when the display system 20 shown in Fig. 2 operates.For asking simple declaration, Fig. 3 only illustrates gate drive signal Y1 ~ Y3 representatively.As shown in Figure 3, when drive element of the grid GDU1 is for being increased to noble potential VGH at time point T1 by gate drive signal Y1, the resistance value that control module 204 adjusts variable resistor RSW1 is resistance value R1, to strengthen the driving force of drive element of the grid GDU1.Now, the resistance value of variable resistor RSW2 ~ RSWn also can be adjusted to resistance value R2 by control module 204, to reduce the driving force of drive element of the grid GDU2 ~ GDUn, thus reduces the impact of the signal on data line DL1 ~ DLm for scanning linear SL2 ~ SLn.Next, at time point T2, drive element of the grid GDU1 for gate drive signal Y1 is reduced to electronegative potential VGL and drive element of the grid GDU2 for gate drive signal Y2 is increased to noble potential VGH.The resistance value of variable resistor RSW2 can be adjusted to resistance value R1 at time point T2 by control module 204, and the resistance value of variable resistor RSW3 ~ RSWn is still maintained resistance value R2.Should be noted, control module 204 is that the resistance value of variable resistor RSW1 is just adjusted to resistance value R2, to guarantee that drive element of the grid GDU1 has enough driving forces at time point T2 and rapidly gate drive signal Y1 is reduced to electronegative potential VGL by noble potential VGH by a time point T3 after time point T2.Accordingly, the driving force of drive element of the grid GDU2 can be enhanced, and the driving force of drive element of the grid GDU1, GDU3 ~ GDUn can be lowered, reduce the object of the signal on data line DL1 ~ DLm for scanning linear SL1, SL3 ~ SLn impact to reach, all the other by that analogy.In other words, control module 204 is that (the time interval TP1 as between signal time point T1 and time point T2) and gate drive signal indicate and stop in an activation sweep trace time interval subsequently (time interval as between time point T2 and time point T3) in a time interval of gate drive signal instruction activation sweep trace, the variable-resistance resistance value that adjustment is coupled to this gate drive signal is resistance value R1, can be driven normally to make sweep trace.Now, it is resistance value R2 that control module 204 maintains remaining variable-resistance resistance value, to alleviate the interference of the signal on data line DL1 ~ DLm for scanning linear SL1 ~ SLn, thus avoids display system 20 malfunction.
According to different designs theory and application, display system 20 can utilize different signals to adjust the output resistance of drive element of the grid GDU1 ~ GDUn.Please refer to Fig. 4, Fig. 4 is the sequential chart of coherent signal when the display system 20 shown in Fig. 2 operates.For asking simple declaration, Fig. 4 only illustrates gate drive signal Y1 ~ Y3 representatively.As shown in Figure 4, cause in sweep trace SL1 ~ SLn in order to avoid gate drive signal Y1 ~ Yn delay has two sweep traces to be enabled simultaneously, display system 20 utilizes a signal OE control gate drive unit 202, with make gate drive signal (as gate drive signal Y1, Y2) adjacent in gate drive signal Y1 ~ Yn indicate activation time (being namely maintained the time of noble potential VGH) to be separated by a time interval TP2.When drive element of the grid GDU1 is for being increased to noble potential VGH at time point T1 by gate drive signal Y1, the resistance value that control module 204 adjusts variable resistor RSW1 is resistance value R1, to strengthen the driving force of drive element of the grid GDU1, thus allow gate drive signal Y1 promote rapidly to cause noble potential VGH.Now, the resistance value of variable resistor RSW2 ~ RSWn also can be adjusted to resistance value R2 by control module 204, to reduce the driving force of drive element of the grid GDU2 ~ GDUn, thus reduces the impact of the signal on data line DL1 ~ DLm for scanning linear SL2 ~ SLn.Next, gate drive signal Y1 can be reduced to electronegative potential VGL at time point T2 by drive element of the grid GDU1.In order to allow gate drive signal Y1 be adjusted to electronegative potential VGL by noble potential VGH rapidly, the resistance value that control module 204 maintains variable resistor RSW1 in time interval TP2 is resistance value R1 and the resistance value maintaining variable resistor RSW2 ~ RSWn is resistance value R2.In brief, control module 204 starts (time interval TP1 as shown in Figure 4 adds time interval TP2) in an activation scanning linear SL1 time interval subsequently at gate drive signal Y1, the resistance value of variable resistor GSW1 is adjusted to resistance value R1, and the resistance value of variable resistor GSW2 ~ GSWn is adjusted to resistance value R2.
Similarly, when drive element of the grid GDU2 is at a time point T3, when gate drive signal Y2 is increased to noble potential VGH, the resistance value that control module 204 adjusts variable resistor RSW2 is resistance value R1, to strengthen the driving force of drive element of the grid GDU2, thus allow gate drive signal Y2 promote rapidly to cause noble potential VGH.Now, the resistance value of variable resistor RSW1 also can be adjusted to resistance value R2 and the resistance value of variable resistor RSW3 ~ RSWn is maintained resistance value R2 by control module 204, to reduce the driving force of drive element of the grid GDU1, GDU3 ~ GDUn, thus reduce the impact of the signal on data line DL1 ~ DLm for scanning linear SL1, SL3 ~ SLn.Next, gate drive signal Y2 can be reduced to electronegative potential VGL at time point T4 by drive element of the grid GDU2.In order to allow gate drive signal Y2 be adjusted to electronegative potential VGL by noble potential VGH rapidly, the resistance value that control module 204 maintains variable resistor RSW2 is resistance value R1, and the resistance value maintaining variable resistor RSW1, RSW3 ~ RSWn is maintained resistance value R2.All the other by that analogy.Accordingly, the signal on data line DL1 ~ DLm can be lowered for the impact of gate drive apparatus 202, thus avoids display system 20 malfunction.
Please refer to Fig. 5, Fig. 5 is the sequential chart of coherent signal when the display system 20 shown in Fig. 2 operates.For asking simple declaration, Fig. 5 only illustrates gate drive signal Y1 ~ Y3 representatively.Be similar to Fig. 4, cause in sweep trace SL1 ~ SLn in order to avoid gate drive signal Y1 ~ Yn delay has two sweep traces to be enabled simultaneously, display system 20 utilizes a signal OE control gate drive unit 202, with make adjacent in gate drive signal Y1 ~ Yn gate drive signal instruction activation time to be separated by a time interval TP2.When drive element of the grid GDU1 is for being increased to noble potential VGH at time point T1 by gate drive signal Y1, the resistance value that control module 204 adjusts variable resistor RSW1 is resistance value R1, to strengthen the driving force of drive element of the grid GDU1, thus allow gate drive signal Y1 promote rapidly to cause noble potential VGH.Now, the resistance value of variable resistor RSW2 ~ RSWn also can be adjusted to resistance value R2 by control module 204, to reduce the driving force of drive element of the grid GDU2 ~ GDUn, thus reduces the impact of the signal on data line DL1 ~ DLm for scanning linear SL2 ~ SLn.With Fig. 4 unlike, when drive element of the grid GDU1 is for being reduced to electronegative potential VGL at time point T2 by gate drive signal Y1, control module 204 is another according to a clock signal CKV, after time point T2, count a cycle at a time interval TP3(such as clock signal CKV) in maintain variable resistor RSW1 resistance value be resistance value R1, be adjusted to electronegative potential VGL by noble potential VGH rapidly to allow gate drive signal Y1.
Next, when drive element of the grid GDU2 is at time point T3, when gate drive signal Y2 is increased to noble potential VGH, the resistance value that control module 204 adjusts variable resistor RSW2 is resistance value R1, to strengthen the driving force of drive element of the grid GDU2, thus allow gate drive signal Y2 promote rapidly to cause noble potential VGH.Now, the resistance value of variable resistor RSW3 ~ RSWn can be maintained resistance value R2 by control module 204, to reduce the driving force of drive element of the grid GDU3 ~ GDUn, thus reduces the impact of the signal on data line DL1 ~ DLm for scanning linear SL3 ~ SLn.It is noted that be arranged in the time interval TP3 after time point T2 due to time point T3, therefore the resistance value of variable resistor RSW1 is still maintained resistance value R1 at time point T3.Until the time interval TP3 after time point T2 terminates, the resistance value of variable resistor RSW1 is just adjusted to resistance value R2 by control module 204.All the other by that analogy.Thus, the signal on data line DL1 ~ DLm can be lowered for the interference of gate drive apparatus 202, thus avoids display system 20 malfunction.
It should be noted that above embodiment is by adjusting in display system for driving the output resistance of the gate drive apparatus of sweep trace adaptively, to alleviate the interference of data line signal for gate drive apparatus, thus avoids display system malfunction.According to different application and design concept, those skilled in the art should implement suitable change and amendment according to this.For example, please refer to Fig. 2, when gate drive signal Ya in gate drive signal Y1 ~ Yn is converted to noble potential VGH by electronegative potential VGL and gate drive signal Yx is converted to electronegative potential VGL by noble potential VGH, the output resistance (i.e. variable resistor RSWa, RSWx) that control module 204 can adjust drive element of the grid GDUa, the GDUx producing gate drive signal Ya, Yx is resistance value R1.Now, according to different application, the number that the resistance value of the variable resistor (namely variable resistor RSW1 ~ RSWn deducts variable resistor RSWa, RSWx) being coupled to all the other drive element of the grid is adjusted to resistance value R2 can change by control module 204 according to this.For example, the variable-resistance half being coupled to all the other drive element of the grid can be adjusted to resistance value R2 by control module 204, also can reach and alleviate the object of data line signal for the interference of gate drive apparatus.
Please refer to Fig. 6, Fig. 6 is the schematic diagram of the embodiment of the present invention one drive element of the grid 60.Drive element of the grid 60 is another implementation of the GDU1 ~ GDUn of drive element of the grid shown in Fig. 2, is used for producing gate drive signal Y1 ~ Yn wherein one (showing it with gate drive signal Yi in figure 6).As shown in Figure 6, drive element of the grid 60 comprises control module 600, output stage 602.Control module 600 is used for controlling output stage 602, drives corresponding sweep trace to produce gate drive signal Yi at an output terminal OUT.In addition, control module 600 can according to the control signal of outside (control signal that control module 204 as shown in Figure 2 exports), the output resistance of adjustment output stage 602, thus reaches and alleviate the impact of data line signal on drive element of the grid 60.For example, control module 600 can comprise an a current source ICS and transistor MN1, and output stage 602 comprises transistor MN2, MP1.Wherein transistor MN1, MN2 forms a current mirror (current mirror), with the electric current I produced at output terminal OUT current source ICS.Be coupled to the control signal VGP of the grid G P1 of transistor MP1 by adjustment, control module 600 can control the voltage level of gate drive signal Yi.In addition, control module 600 also according to external control signal (not being illustrated in Fig. 6), can change the current value of the electric current I that current source ICS produces, to adjust the output resistance of output stage 602.For example, when control module 600 reduces the current value of the electric current I that current source ICS produces, the electric conduction resistive of transistor MN1 is large, causes the output resistance of output stage 602 to increase.Relatively, when control module 600 increases the current value of the electric current I that current source ICS produces, the conducting resistance of transistor MN1 diminishes, and causes the output resistance of output stage 602 to reduce.Thus, drive element of the grid 60 can be used to produce gate drive signal Yi, and the output resistance of drive element of the grid 60 can be properly adjusted, thus reaches the object alleviating data line signal and affect for drive element of the grid 60.
The mode that in above-described embodiment, control module 204 adjusts grid control device 202 can be summarized as a driving method 70.Driving method 70 can be used for the display system comprising a gate drive apparatus and a panel, and comprises the following steps:
Step 700: start.
