As shown in Figure 2, the embodiment of the present invention is described for liquid crystal display, the display base plate that the present embodiment provides, comprise the multiple pixel cells in array distribution, pixel cell comprises the first sub-pixel adjacent one another are, the second sub-pixel and the 3rd sub-pixel, and three sub-pixels are all rectangle.Namely these three sub-pixels are red (R), green (G), blue (B) three sub-pixels, and the color of three sub-pixels can be distributed arbitrarily, and three sub-pixels in the present embodiment are corresponding green, red, blue respectively.
Wherein, preferred green sub-pixels is transversely arranged as the first sub-pixel, and the line direction namely along pixel unit array is arranged, and namely the long limit of green sub-pixels is parallel to line direction.Red sub-pixel and blue subpixels are all longitudinally arranged respectively as the second sub-pixel and the 3rd sub-pixel, and the column direction namely along pixel unit array is arranged, and namely the long limit of red sub-pixel and the long limit of blue subpixels are parallel to column direction; And the long limit of red sub-pixel and blue subpixels is adjacent.The minor face of the long limit of green sub-pixels and red sub-pixel, blue subpixels is adjacent.
As can be seen from Figure 2, green sub-pixels is disposed across the top of red sub-pixel, blue subpixels, and three sub-pixels are put in the mode of similar triangle disposition.Like this, just reduce the size of pixel cell transverse direction, and increase the size of pixel cell longitudinal direction, therefore when the overall dimensions of display panel is constant, just can increase the quantity n of display panel at the pixel cell of transverse direction, decrease the quantity m of display panel at the pixel cell of longitudinal direction simultaneously.
Suppose that the shape of each sub-pixel is identical, the wide and long of each sub-pixel is respectively a and b, then the horizontal and vertical length of existing pixel cell is respectively 3a and b(as shown in Figure 1), former display panel is respectively n and m in the quantity of horizontal and vertical pixel cell.And can find out according to Fig. 2, in the present embodiment, the horizontal and vertical length of pixel cell is respectively b and a+b, and so when the overall dimensions of display panel is constant, in the present embodiment, display panel is in the quantity of the pixel cell of transverse directionin the quantity of the pixel cell of longitudinal direction
As a preferred version, the length breadth ratio of each sub-pixel is all less than 3:1, and the present embodiment is described for length breadth ratio b:a=2:1, thenif it is in the display panel of 1280 × 800 that the present embodiment is applied in former resolution n × m, then, after the display base plate that the application embodiment of the present invention provides, can place in the transverse direction of display panelindividual pixel cell, in longitudinal placementindividual pixel cell, substitutes into formulacan calculate the pixel-intensive degree PPI ' made new advances, new PPI ' is 1.32 with the ratio of former PPI, improves 32% by pixel-intensive degree.Therefore, display base plate provided by the invention has higher pixel-intensive degree, thus meets the high-resolution requirement of product.In addition, as shown in Figure 3 a and Figure 3 b shows, compared with the arrangement mode of existing display base plate sub-pixel, when in the present embodiment, three colors show jointly, the region of synthesis light is larger, and color is more even, for white light (W) in Fig. 3 a and Fig. 3 b.
