Embodiment
To make the object, technical solutions and advantages of the present invention clearer, the present invention is made into one below in conjunction with attached drawing
It is described in detail on step ground.
As shown in Figure 1, in the embodiment of the present invention one, there is provided a kind of liquid crystal panel, including for showing the aobvious of image
Show region AA and be arranged at the virtual pixel area BB of display area AA peripheries, the actual pixels unit A of display area AA with
Determinant matrix arrangement is distributed, and among the every a line actual pixels unit both sides set along horizontal line direction at least on side
It is corresponding that at least one virtual pixel cell belonged in virtual pixel area BB is distributed with, and each virtual pixel cell is remote
The side of display area AA is arranged with corresponding virtual data line DDL；
It is specific to set each virtual pixel cell in the AA of display area corresponding to all actual pixels unit rows to be measured
Structure virtual pixel cell B, and main the pixel electrode M and pixel electrode S in each specific structure virtual pixel cell B are same
When be connected in the AA of display area on the data cable DL of a certain row actual pixels unit and also while to be connected to corresponding one virtual
On data cable DDL so that after a certain row to be measured of actual pixels unit is lit in the AA of display area, can be lighted by monitoring capable
The voltage for connecting virtual data line DDL on the specific structure virtual pixel cell B of horizontal distribution corresponding to actual pixels unit comes
Determine to light the optimal public electrode voltages and optimal data-signal input time and level of row fever actual pixels unit
Value.
It is understood that the specific structure of horizontal distribution corresponding to capable actual pixels unit is lighted for the ease of monitoring
Connect the voltage of virtual data line DDL on virtual pixel cell B, can be by the B connections of each specific structure virtual pixel cell
In on an independent virtual data line DDL, so that the specific structure virtual pixel list of virtual voltage can be monitored by increase

Connect, and in voltage course is detected, to light row institute right to observe for the row actual pixels unit for lighting display area AA in batches
The voltage for answering specific structure virtual pixel cell B to reflect.
In one embodiment, as shown in Figures 2 and 3, each actual pixels unit row institute to be measured is right in the AA of display area
The specific structure virtual pixel cell B that should be set is one, and each actual pixels unit row institute to be measured in the AA of display area
The specific structure virtual pixel cell B being correspondingly arranged is while positioned at the side of display area AA（Left side and figure including Fig. 2
3 right side）And be connected to the rule that is spacedly distributed on corresponding virtual data line DDL, thus can be to avoid because specific
Structure virtual pixel cell B is excessively intensive and produces situation about obscuring.
In another embodiment, as shown in figure 4, being set in the AA of display area corresponding to each actual pixels unit row to be measured
The specific structure virtual pixel cell B put is one, and in the AA of display area corresponding to all actual pixels unit rows to be measured
The specific structure virtual pixel cell B of setting is interspersed in the both sides of display area AA；Wherein, the spy of display area AA sides
Determine structure virtual pixel cell B while be connected with corresponding virtual data line DDL, the specific structure virtual pixel list of opposite side
First B is connected with corresponding another virtual data line DDL at the same time, can so be distinguished by two difference virtual data line DDL
The corresponding voltage for lighting row detecting.
