Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, the embodiment of the present invention provides a kind of array base palte, comprise longitudinal data line 5 and horizontal grid line 6, data line 5 and the multiple pixel cell of grid line 6 intersection definition, each pixel cell comprises pixel electrode 1 and public electrode 2, in Fig. 1, point-like fill area is public electrode 2, also public electrode 2 is had to be communicated with the public electrode in each pixel cell in data line 5 and the position of grid line 6, pixel electrode 1 in each pixel cell and public electrode 2 are tabular and slit-shaped respectively, this array base palte also comprises: be positioned at the metal wire 3 of different layers with public electrode 2, particularly, metal wire 3 can be line longitudinal as shown in Figure 1, also can be horizontal line, metal wire 3 place layer and public electrode 2 are provided with insulation course between layers, insulation course is provided with multiple via hole 4 in the region of metal wire 3, and metal wire 3 is connected with public electrode 2 by via hole 4, and multiple via hole 4 is positioned at viewing area.
It should be noted that, except the pixel electrode 1 shown in Fig. 1 in each pixel cell is tabular, public electrode 2 is situations of slit-shaped, and can also be slit-shaped for pixel electrode 1, public electrode 2 be situations of tabular.
Array base palte in the embodiment of the present invention, owing to being interconnected by multiple positions of multiple via hole by metal wire and public electrode, be equivalent to metal wire and public electrode parallel connection, not only reduce the resistance of public electrode, and improve the homogeneity of public electrode voltages.
Further, metal wire 3 can between adjacent pixel cell.Metal wire 3 can be blocked by the black matrix at data line and grid line place, can not transmitance be affected.
Further, as shown in Figure 2, via hole 4 can be arranged at the position in grid line 6 region overlapping with metal wire 3, is convenient to block via hole 4 by the black matrix at grid line 6 place.
Further, metal wire 3 is arranged between two adjacent row pixel cells.The number that metal wire 3 is concrete and distribution mode can be arranged according to the uniformity requirements of cost and public electrode voltages.
Further, one row metal wire 3 is set every two row pixel cells.
As shown in Figure 2, particularly, above-mentioned array base palte can be double grid (Dual Gate) array base palte, is namely driven the pixel of same a line by two grid lines 6, the quantity of data line 5 can be reduced by half like this, thus decrease the number of data IC joint.In double grid array base palte, often row pixel cell is divided into multiple pixel cell group 8, and each pixel cell group 8 is made up of adjacent two pixel cells; Often be provided with the first grid line above row pixel cell, often be provided with the second grid line below row pixel cell, first grid line and the second grid line are used for driving two pixel cells in each pixel cell group 8 respectively, and two pixel cells in each pixel cell group 8 are connected to same data line 5; Be provided with virtual data line (Dummy Data Line) between adjacent pixel cell group 8, virtual data line does not have actual effect in the process driven.Above-mentioned metal wire 3 can be virtual data line.Effectively can utilize like this and in driving process, originally there is no the virtual data line of practical function as metal wire 3 to reduce the resistance of public electrode and to improve the homogeneity of public electrode voltages.
Accordingly, in double grid array base palte, between two adjacent row pixel cells, be provided with two row grid lines 6; Via hole 4 is arranged at the first grid line adjacent between adjacent rows pixel cell and the region of the second grid line and virtual data line overlap.This is because virtual data line is thinner, too large-sized black matrix is not needed to block, and make the larger size of via hole needs, if make via hole 4 in other positions of virtual data line, the black matrix of large-size is then needed to block, thus reduce transmitance, and the size of two row grid lines 6 is enough large to cover via hole 4, therefore can not reduce transmitance.
It should be noted that, a line via hole 4 can be all set at every a line pixel cell, or a line via hole 4 is just set in every line.Above-mentioned via hole 4 does not need extra mask (Mask) manufacturing process, because the viewing area periphery of array base palte just needs to make via hole usually, only needs the figure increasing above-mentioned via hole 4 in original mask plate to realize.Array base palte in the embodiment of the present invention is applicable to variously all be arranged in the display device on array base palte by public electrode and pixel electrode, such as adopt the screen of ADS technology or adopt plane conversion (In-Plane Switching, be called for short IPS) screen of technology, for different application, the improvement opportunity of ADS technology has high permeability I-ADS technology, high aperture H-ADS and high resolving power S-ADS technology etc., and the array base palte that the embodiment of the present invention provides is the array base palte adopting HADS technology display device.
