The drive circuit board 10 can include a grid drive circuit board, a source drive circuit board and a compensation unit 11. The substrate 20 is provided with a pixel array 21, and each pixel in the pixel array 21 include a liquid crystal unit, and two poles of an applied electric filed of liquid crystal unit are a pixel electrode and a common electrode respectively. The pixel electrode is connected to a scan line and a data line through a thin film transistor (TFT). The common electrodes corresponding to each liquid crystal unit are connected with each other and form a common electrode wire 30. The drive circuit board 10 can be connected with the substrate 20 through the COF, the grid drive circuit board is connected with each scan line to drive the TFT corresponding to each row of pixel to be turned on or off, and the source drive circuit board is connected with the data line to input data voltage to each pixel, the compensation unit 11 is connected with the common electrode wire 30 for the inverse compensation. A drive architecture of the display panel is different, and a distribution of the common electrode wire 30 is also different. FIG. 1 shows a distribution of the common electrode wire 30 when the display panel is driven in the FFS or IPS display mode. For this kind of display panel, the common electrode wires 30 are all distributed on the array substrate 22 (which is generally called ACOM, a hollow circle as shown in FIG. 1). FIG. 2 shows a distribution of the common electrode wire 30 when the display panel is driven in the TN or VA display mode. For this kind of display panel, the common electrode wire 30 is distributed on the array substrate 22 and the color film substrate 23 (the common electrode wire 30 on the array substrate 22 is generally called ACOM, a hollow circle as shown in FIG. 2; the common electrode wire 30 on the color film substrate 23 is generally called CCOM, a solid circle as shown in FIG. 2). The common electrode wires 30 shown in FIG. 1 and FIG. 2 are only examples, a specific distribution can be provided according to the need.

As shown in FIG. 3 and FIG. 4, FIG. 3 is a schematic connection diagram of a common electrode without an inverse compensation in the FFS/IPS mode of the present disclosure, and FIG. 4 is a schematic connection diagram of a common electrode without an inverse compensation in the TN/VA mode of the present disclosure.

Thus, the compensation unit includes a detection terminal in for accessing to a voltage of the common electrode wire and a feedback terminal out for feeding back a compensation voltage to the common electrode wire.

In this embodiment, at least one common electrode wire 30 is provided with a first connecting wire 50 and at least one common electrode wire 30 is provided with a second connecting wire 60, the first connecting wire 50 is connected with the detection terminal in, the second connecting wire 60 is connected with the feedback terminal out, both the first connecting wire 50 and the second connecting wire 60 are provided with a configuration section 70. When the configuration section 70 is provided with the connector, the connecting wire corresponding to the configuration section 70 is on an on-state. When the configuration section 70 is provided without the connector, the connecting wire corresponding to the configuration section 70 is on an off-state.

The display panel can be provided with more common electrode wires 30, such as 8 or 16 common electrode wires 30. The configuration section 70 of the connecting wire does not exist conducting wire, therefore, the connecting wire on the configuration section 70 is equivalent to be in an off-state. The connecting wires at both ends can be connected by providing a connector on the configuration section 70, so that the common electrode wire 30 forms a circuit with the detection terminal in or the feedback terminal out.

In this embodiment, the debugging personnel can set the configuration section 70 on each connecting wire to adjust the position and quantity of the detection point and the position and quantity of the feedback point when debugging the inverse compensation of the common electrode. Since a circuit is pre-formed between the common electrode wire 30 and the detection terminal in and the feedback terminal out, the debugging personnel can adjust the inverse compensation method flexibly. When the chosen compensation method fails to achieve the expected compensation effect, each configuration section 70 can be adjusted to change the wire to avoid rewiring.

It should be noted that, the connector can be a switch tube in an on-state. The configuration section 70 can be pre-configured with the switch tube. The switch tube can be switched from on-state and off-state under control of the drive circuit board 10. When debugging the inverse compensation of the common electrode, the debugging personnel can directly adjust the state of each switch tube to adjust the position and quantity of the detection point and the position and quantity of the feedback point.
