Include two row display pixels, each row display pixel includes being displayed in red the three row sub-pixels of R, green G and blue B respectively.
It is high potential in scanning signal Gate it should be noted that as shown in figure 3, during the driving of existing display panel
Time in, be displayed in blue in a display pixel B sub-pixel 40 (i.e. with 116 phase of third data line 113 or the 6th data line
Even sub-pixel 40) charging time it is most short, it is worst so as to be displayed in blue the charging effect of the sub-pixel 40 of B, accordingly, in order to carry
The charging effect for the sub-pixel 40 for being displayed in blue B is risen, in some embodiments of the invention, can also be extended in each display pixel
It is displayed in blue 40 charging time of sub-pixel of B namely so that the opening time of the first switch 211 and second switch 212 is equal
Less than the opening time of third switch 213, the opening time of 214 and the 5th switch 215 of the 4th switch is respectively less than institute
The opening time of the 6th switch 216 is stated, for example, setting first switch 211, the switch of second switch the 212, the 4th 214 and the 5th are opened
The opening time for closing 215 is 4 μ s, and the opening time of 213 and the 6th switch 216 of third switch is 4.5 μ s.
When it is implemented, the first switch 211, second switch 212, third switch 213 can be by changing corresponding to it
First control signal SW1, second control signal SW2 and the third controls of control signal SW3 or the 4th signal SW4, the 5th control
Signal SW5 processed and the 6th controls the pulse duration of signal SW6 to be adjusted.

215 and the 6th switch 216 be thin film transistor (TFT), further, due to the size of the control signal voltage of multiplexer 20
It can't change with the change of the polarity of data-signal, therefore, the data-signal of negative polarity is to the charging effect of sub-pixel
It must be better than the data-signal of positive polarity, reason is the first switch 211, second switch 212, third switch the 213, the 4th
Gate-source voltage difference Vgs during the data-signal of 216 access positive polarity of the 214, the 5th switch 215 of switch or the 6th switch is less than it
Access the gate-source voltage difference Vgs during data-signal of negative polarity.
For the charging effect to sub-pixel of the data-signal of the data-signal and positive polarity of balanced negative polarity, in this hair
In some bright embodiments, it can also reduce the charging time of the display pixel for the data-signal for receiving negative polarity namely be arranged on
In one frame image time, when the first data-signal Data1 is negative polarity, the first switch 211, second switch 212
And third switch 213 opening time be respectively smaller than the 4th switch the 214, the 5th switch 215 and the 6th switch 216 unlatching when
Between；When the first data-signal Data1 is positive polarity, the first switch 211, second switch 212 and third switch 213
Opening time be respectively greater than the 4th switch the 214, the 5th switch 215 and the 6th switch 216 opening time.For example, when described
When first data-signal Data1 is positive polarity, the opening time of first switch 211, second switch 212 and third switch 213 is equal
For 4.5 μ s, the opening time of the 214, the 5th switch 215 of the 4th switch and the 6th switch 216 is 4 μ s.
Meanwhile as shown in Figure 4 and Figure 5, in order to overcome the data-signal of above-mentioned positive-negative polarity and different sub- picture simultaneously
Influence of the length of charging duration between element to the charging effect of sub-pixel, in some embodiments of the invention, can also be
Filling for the display pixel for the data-signal for receiving negative polarity is reduced while extending the charging time of sub-pixel 50 for being displayed in blue B
The electric time, for example, in a frame image time, when the first data-signal Data1 is positive polarity, first switch 211, the
The opening time that two switches 212, third switch 213 is respectively 4.5 μ s, 4.5 μ s and 5 μ s, and the 4th switch the 214, the 5th switchs 215
And the 6th switch 216 opening time be respectively 4 μ s, 4 μ s and 4.5 μ s.
It is understood that described in a frame image time, the first switch 211, second switch 212, third are opened
It closes the 214, the 5th switch 215 of the 213, the 4th switch and the 6th 216 opening times of switch can be adjusted as needed, although on
The opening time for stating 214 and the 5th switch 215 of the first switch 211 illustrated in embodiment and the switch of second switch the 212, the 4th is equal
It is equal, but it is not limitation of the present invention, and actually it can not also be waited.Preferably, in a frame image time, described
One switch 211, second switch 212, third switch the unlatching of the 214, the 5th switch 215 of the 213, the 4th switch and the 6th switch 216
Time can be adjusted in the range of 0 μ s to 5 μ s.
Specifically, the display panel 10 is the display panel using oxide semiconductor thin-film transistor, it is preferable that institute
The large scale display panel that display panel is more than 65 cun for size is stated, is exported in data-signal needed for large scale display panel
The quantity at end 311 is more, can give full play to the present invention and reduce 311 quantity of data signal output and oxide semiconductor thin-film
