Stating the pixel that odd-numbered line grid line 125 is correspondingly connected with is the first pixel 115, and the even number line grid line 126 is correspondingly connected with
The pixel be the second pixel 116.
The corresponding pixel of odd-numbered line grid line 125 is the first pixel 115, and even number line grid line 126 is corresponding described
Pixel is the second pixel 116, i.e. the first pixel 115 and the setting of the second pixel 116 interval.Further away from data drive circuit 120
The gate drive voltage of pixel, corresponding grid line is bigger, and the remoter compensation of the distance whole displays for making display panel equal more

The side of beam.First side, 123 outermost end is the first row grid line, and 124 outermost end of second side is line n grid line.It certainly can also
To be set as, the first side 123 is the side of the grid line end of scan, and second side 124 is the side that grid line starts scanning.
Specifically, the odd-numbered line grid line 125 is remoter apart from first data drive circuit 121, the odd-numbered line
The gate drive voltage of grid line 125 is bigger；It is coupled in odd-numbered line grid described in every a line of first data drive circuit 121
The gate drive voltage of polar curve 125 is all different；The even number line grid line 126 is apart from second data drive circuit 122
Remoter, the gate drive voltage of the even number line grid line 126 is bigger；It is coupled in the every of second data drive circuit 122

Together.As long as specifically, odd-numbered line grid line 125 and the first data drive circuit 121, even number line grid line 126 and the second data
The distance one of driving circuit 122 increases a bit, and a bit thanks to damage, corresponding gate drive voltage is increased by some data-signal,
I.e. a little corresponding gate drive voltage compensates for a bit for data-signal loss.Such as 960 grid lines, distance is divided into
960 distances, each distance carry out the compensation of different amplitudes, and how much data-signal loss compensates for how many, accomplished high-precision
Degree is adjusted.All increase relative to by the gate drive voltage of corresponding odd-numbered line grid line 125 and even number line grid line 126 in this way
It is determined for the scheme of value to some biggish voltage, to make the display picture brightness of display panel more evenly.
As shown in Figure 8, naturally it is also possible to be set as, the odd-numbered line grid line 125 drives according to far from first data
The distance difference of dynamic circuit 121 is at least divided into two odd-numbered line scanning groups 127；The odd-numbered line scanning group 127 is apart from described
First data drive circuit 121 is remoter, the gate driving of the odd-numbered line grid line 125 in the odd-numbered line scanning group 127
Voltage is bigger；The gate drive voltage phase of all odd-numbered line grid lines 125 in the same odd-numbered line scanning group 127
Together.The even number line grid line 126 is at least divided into two according to the distance difference far from second data drive circuit 122

The gate drive voltage of the even number line grid line 126 in scanning group 128 is bigger；The same even number line scanning group 128
In all even number line grid lines 126 gate drive voltage it is identical.
This programme divides different grid lines at a distance from the first data drive circuit 121, the second data drive circuit 122
It is not divided into different odd-numbered line scanning group and even number line scanning group, each odd-numbered line scanning group, even number line scanning group difference
A distance is calculated, the gate drive voltage of the more remote corresponding compensation of scanning group range data driving circuit 120 is bigger, needs in this way
The quantity of the different value for the gate drive voltage wanted controls in suitable range；Realizing the remote compensation gate drive voltage of distance
While realizing display panel brightness uniformity greatly, the realization difficulty of technique and circuit is reduced, production cost is advantageously reduced.
For example, by taking odd-numbered line grid line 125 as an example, the gate driving circuit 117 according to used by display panel
Driving capability is different, and it is an odd-numbered line scanning group or 50 or 100 every every that every five odd-numbered line grid lines 125, which are arranged,
Odd-numbered line grid line 125 be an odd-numbered line scanning group, odd-numbered line grid line 125 divide odd-numbered line scanning group quantity, with
The driving capability (quantity for the different gate drive voltages that can be exported) of gate driving circuit 117 is corresponding, sets respectively in this way
Set a gate drive voltage.

The corresponding first grid driving voltage of grid line 125 is bigger；The even number line grid line 126 is apart from the second data-driven electricity
Road 122 is remoter, and the corresponding second grid driving voltage of the even number line grid line 126 is bigger.
In the present solution, corresponding first pixel 115 of odd-numbered line grid line 125 is controlled by first grid driving circuit 118
System is opened, and corresponding second pixel 116 of even number line grid line 126 is opened by the control of second grid driving circuit 119, due to the
One pixel 115 and the second pixel 116 are by different data drive circuits 120, and thus, gate driving circuit 117 can be set respectively
The left and right side in display panel is set, to be scanned respectively to grid line, then by timing controller come when controlling
Ordered pair is answered, this advantageously reduces the requirement of 117 driving capability of gate driving circuit and the requirement of circuit design difficulty；Specifically, right
