Detailed description of the invention
For making those skilled in the art be more fully understood that technical scheme, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Embodiment 1:
The present embodiment provides a kind of display base plate, and this display base plate effectively reduces the region area arranged shared by data wire and public electrode wire, reduces the area needing black matrix occlusion area, increases the aperture opening ratio of pixel region.
The display base plate of the present embodiment, including dot structure, data wire, grid line, data wire is arranged with grid line transposition insulator, dot structure is arranged in arrays, the dot structure being positioned at same column is connected with same data wire, wherein, with in two data line that often adjacent two row dot structures connect respectively gap between these adjacent two row dot structures.
Fig. 4 is the structural representation that the display base plate of the present embodiment is not provided with black matrix, and as shown in Figure 4, data wire 1 is arranged with grid line 2 transposition insulator, and wherein, data wire 1 extends along column direction, and grid line 2 extends in the row direction. Each dot structure is arranged in a pixel region, and each dot structure includes pixel electrode 3, public electrode and thin film transistor (TFT) 4, and the dot structure being positioned at colleague is connected with same grid line 2, arranges a grid line 2 in the gap between every adjacent rows dot structure; The dot structure being positioned at same column is connected with same data wire 1, wherein, with in two data line 1 that often adjacent two row dot structures connect respectively gap between these adjacent two row dot structures, simultaneously, with be provided with data wire 1 gap be close to gap, two, left and right in be then not provided with data wire 1, so, data wire 1 concentrated setting, it is possible to reduce the region area arranged shared by data wire 1.
Data wire 1 and grid line 2 all adopt metal material to make, it is necessary to adopt black matrix to block data wire 1 and grid line 2, in case leak-stopping light, improve display effect. Fig. 5 is the structural representation after the display base plate of Fig. 4 arranges black matrix, as shown in Figure 5, black matrix 6 is arranged in the gap between the often adjacent two row dot structures being provided with data wire 1 and is arranged in the gap between the every adjacent rows dot structure being provided with grid line 2, and the frontal projected area of data wire 1 and grid line 2 falls completely within the area of black matrix 6. Because arranging the region area shared by data wire 1 and compare that existing to arrange form relatively small, thus relatively reducing the area needing black matrix 6 occlusion area, increasing the aperture opening ratio of pixel region.
In addition, dot structure includes public electrode, display base plate also includes public electrode wire 5, and public electrode wire 5 is arranged in the gap between the adjacent two row dot structures being not provided with data wire 1, and public electrode wire 5 is connected respectively with the public electrode of the two row dot structures being arranged in its both sides. It is to say, data wire 1 and public electrode wire 5 are disposed alternately at successively along row to the gap extended. So, compared to the form that arranges of public electrode wire in prior art Fig. 15, the quantity of public electrode wire 5 at least reduces half, simplifies preparation technology, reduces production cost.
Further, public electrode wire 5 adopts transparent material to make, and transparent material includes tin indium oxide (ITO). So, public electrode wire 5 need not adopt black matrix 6 to block, and further reduces the area needing black matrix 6 occlusion area, increases the aperture opening ratio of pixel region.
For reducing the quantity of desired data line 1, thus reducing the area of black matrix 6 occlusion area, the long limit arranging pixel electrode 3 is parallel to grid line 2, and the minor face of pixel electrode 3 is parallel to data wire 1. In size design, the length ratio of the length on the long limit of pixel electrode 3 and the minor face of pixel electrode 3 range for 1��4, it is preferable that the length ratio of the length on the long limit of pixel electrode 3 and the minor face of pixel electrode 3 is 3. So, reduce the quantity of each row pixel electrode 3, increasing the quantity of each column pixel electrode 3, thus decreasing the quantity of data wire 1, increasing the quantity of grid line 2, on the whole, decrease the area of occlusion area needed for black matrix 6, increase the aperture opening ratio of pixel region.
Fig. 6 is the close-up schematic view of the display base plate of Fig. 5, and as shown in Figure 6, the data wire 1 distance apart from black matrix 6 border is A; The width of data wire 1 is D; Minimum technique distance between adjacent data line 1 is S. Therefore, blocking the width of black matrix 6 needed for adjacent two data line 1 is Y=2A+2D+S.
Fig. 6 of the present embodiment Fig. 3 compared to existing technology, needed for blocking adjacent two data line 1, the width of black matrix 6 decreases Z=X-Y=(2A+D+S+C) * 2-(2A+2D+S)=2A+S+2C. As can be seen here, the width of black matrix 6 obtains bigger reduction, and accordingly, the aperture opening ratio of pixel region is greatly improved. According to test determination, the raising scope of the aperture opening ratio of pixel region is 5%��30%.
The display base plate of the present embodiment, first, by being arranged in the gap between these adjacent two row dot structures with two data line 1 that often adjacent two row dot structures connect respectively, decrease the area in region shared by data wire 1, thus decreasing the area needing black matrix 6 occlusion area, improve the aperture opening ratio of pixel region.
Secondly, the long limit arranging pixel electrode 3 is parallel to grid line 2, the minor face of pixel electrode 3 is parallel to data wire 1, decrease the quantity of each row pixel electrode 3, increase the quantity of each column pixel electrode 3, thus decreasing the quantity of data wire 1, increase the quantity of grid line 2, on the whole, further reduce the area of occlusion area needed for black matrix 6, increase the aperture opening ratio of pixel region.
Finally, public electrode wire 5 is arranged in the gap between the adjacent two row dot structures being not provided with data wire 1, and is connected respectively with the public electrode of the two row dot structures being arranged in its both sides. So, relative to prior art, not only the quantity of public electrode wire 5 at least reduces half, decrease production cost, and public electrode wire 5 adopts transparent tin indium oxide to make, make public electrode wire 5 that black matrix 6 need not be adopted to block, further reduce the area of occlusion area needed for black matrix 6, increase the aperture opening ratio of pixel region.
