Since human eye is most strong to the perception of green color brightness change, in Real dot structures, brightness center is green
In sub-pixels, and it is usually that can be defined by the quantity at brightness center for the resolution of a display panel.It is right
For each display unit (including three kinds of color sub-pixels of RGB), green sub-pixels are centrally located, therefore Real
The brightness center of dot structure is located at the centre position of display unit, as shown in Figure 9.
And the brightness center in the present embodiment in dot structure is in the center of display unit, as shown in Figure 10, with aobvious
For showing cells D 1, brightness center is located at sub-pixel 11 and 22 adjacent positions, and the brightness center in other display unit similarly may be used
With determination.
In general, pictorial information to be shown is all on the basis of Real dot structures.Using according to embodiments of the present invention
Dot structure show picture when, need to convert pictorial information to be shown, the pixel in Real dot structures is bright
Degree is assigned in the display unit of dot structure according to the ... of the embodiment of the present invention, at this moment the pixel in Real dot structures and this hair
Display unit in bright dot structure has correspondence.
The present embodiment dot structure shown in Figure 12 is converted to the pictorial information to be shown of dot structure shown in Figure 11
Pictorial information for, wherein Figure 11 is the corresponding dot structure schematic diagram of pictorial information to be shown, and each pixel includes

X6 constitutes a pixel, and x7, x8, x9 constitute a pixel.Similarly, y1~y9 of the second row also constitutes three pixels, third
Capable z1~z9 also constitutes three pixels.
The brightness value of the pictorial information to be shown of dot structure in Figure 11 is converted to what the present embodiment Figure 12 was provided
The brightness value of dot structure.For example, each pixel is corresponded with each display unit in Figure 12 in Figure 11, in display unit D2
The first sub-pixel j, the second sub-pixel i, third sub-pixel o and the 4th sub-pixel p brightness value be pair as shown in Figure 11
3*1 pixel (x4, x5, the x6 answered；y4、y5、y6；Z4, z5, z6) constitute pictorial information to be shown brightness value pass through number
Obtained from conversion.For Figure 11 and Figure 12, display unit cdij (the display lists being made of sub-pixel c, d, i, j in Figure 12
Member) it is corresponding with pixel x4x5x6 in Figure 11 (pixel being made of sub-pixel x4, x5, x6), i.e., it is realized by display unit cdij
The display of the corresponding pictorial informations to be shown of pixel x4x5x6, similarly display unit ijop is corresponding with pixel y4y5y6, display
Unit opuv is corresponding with pixel z4z5z6, and therefore, brightness value transformational relation is：
If L (m) is the corresponding brightness values of pixel m, data conversion formula：

The brightness value of sub-pixel x4, x5, x6 of three kinds of different colours in piece information, L (z4), L (z5), L (z6) indicate figure to be shown
The brightness value of sub-pixel z4, z5, z6 of three kinds of different colours in piece information.Sub-pixel x4, x5 in Figure 11 are only shown with Figure 12
Show that the first pixel that sub-pixel c, d in unit cdij is constituted corresponds to, sub-pixel z5, z6 in Figure 11 only with show in Figure 12 singly
The second sub-pixel that sub-pixel o, p in first ijop are constituted corresponds to.
Dot structure provided in this embodiment is rendered by algorithm, can be obtained and Real dot structure same number
PPI, but the number of the sub-pixel actually needed to is reduced.
Array substrate corresponding with the dot structure of Fig. 5 can be as shown in figure 13, accordingly include 3 controlling grid scan line G1,
G2, G3 and data line Data1, Data2, Data3, Data4, Data5, Data6.One skilled in the art will appreciate that 9 corresponding
3 controlling grid scan lines and 9 data lines are needed in the Real structures at brightness center accordingly.It can be seen that changing due to dot structure
Into the data line number of data line ratio Real dot structures can reduce 1/3 in the present embodiment.
In conclusion width of the present embodiment by the certain sub-pixels (such as red sub-pixel and blue subpixels) of increase,
It can effectively improve aperture opening ratio.Since sub-pixel width increases, the technology difficulty of single pixel can be reduced, while in identical faces
Since number of pixels is reduced in long-pending display area, the number of data line can also be reduced, whole difficulty of processing can be also reduced.
It, can by matching the smaller green sub-pixels of size with red sub-pixel and blue subpixels in each display unit
So that green sub-pixels Size Distribution is more uniform, improving optical display effect.The dot structure is in the display effect for keeping high PPI
Under the premise of fruit, data line number can also be reduced.
