Signal wire, the first subsignal connecting wire 2131 can be data-signal connecting wires, and the second subsignal connecting wire 2132 is
Dummy lines (line simulator), may be referred to Fig. 3, viewing area 21 in Fig. 3 a (longitudinal direction) and second direction b (transverse direction) in the first direction
Resolution ratio is different, i.e., the number of pixel in the two directions is different, and viewing area 21 includes 4 pixel columns, 3 pixel columns, when
So, the pixel in Fig. 3 sets and is only used as a kind of example, and any limit is made in the not pixel setting to array base palte proposed by the present invention
It is fixed.With continued reference to Fig. 3, now, the number that the data-signal connecting wire 2131 of driving voltage is provided to data signal line 212 is
4, because the columns of longitudinal direction is 3, so certain side for having a pixel column (a extends in the first direction) needs to set two single datas
Signal connecting wire 2131, because the side of the pixel column is provided with more data-signal connecting wire 2131, the i.e. pixel column
Being had a great influence by electric field caused by data-signal connecting wire 2131, its display effect will differ from other pixel columns,
It is likely to cause colourity or brightness is inconsistent, reduce overall display effect, in order to prevent the problem, there is provided as dummy
Second subsignal connecting wire 2132 of line so that the electric field environment residing for each pixel is as consistent as possible, so as to improve display
Effect, specifically, can be with pixel column (a extends in the first direction) for unit so that the signal being distributed in each pixel column connects
It is identical to connect the number of wire 213, can also be and array base palte is divided into several identical repeat units, and each repeats list
The number of signal connecting wire 213 in member is identical.But if dummy lines are used merely to equilibrium electric field environment, on the one hand its
Idle state is chronically at, can be produced between another aspect dummy lines and data signal line 212 or public voltage signal line need not
The coupled capacitor wanted, increase the capacitive load of array base palte, the second subsignal connection therefore, in the present invention at least be present and lead
Line 2132 electrically connects with public voltage signal line 214, is powered to public voltage signal line 214 so that and both potentials are identical, so as to
The coupled capacitor between the second subsignal connecting wire 2132 and public voltage signal line 214 can be reduced, reduce capacitive load,
Improve display effect, in addition, in the prior art, upside non-display area 22 (namely upper side frame) or downside it is non-
Viewing area 22 (namely lower frame) is provided with the integrated circuit for controlling display, in order to be supplied to each public voltage signal line 214
Electricity is, it is necessary to which the non-display area 22 (namely left frame and left frame) in the left and right sides sets the power supply of public voltage signal line 214
Circuit, so that integrated circuit can be applied common electric voltage to common electric voltage by the supply line of public voltage signal line 214
Signal wire, in the present invention, it is used as by the second subsignal connecting wire 2132 positioned at viewing area to public voltage signal line
The supply line of 214 power supplies, viewing area, Ke Yijin are also disposed at by the supply line of at least part public voltage signal line 214
Reduce to one step the size of non-display area, expand the area of viewing area, improve screen accounting.
