Shown in Figure 3, be the schematic diagram 300 according to the pel array in the dot structure of the application's embodiment.
The dot structure of the present embodiment, comprises pel array as shown in Figure 3.Wherein, pel array comprises along spaced first pixel sequence 31 and the second pixel sequence 32 of first direction.
The first sub-pixel 311, first sub-pixel 311 that first pixel sequence 31 comprises along second direction repeated arrangement has the first color.
Second pixel sequence 32 comprises the second sub-pixel 322 and the 3rd sub-pixel 323 that replace repeated arrangement along second direction.
Two second sub-pixels 322,325 adjacent along first direction are alternatively set as the second color and the 3rd color, and are alternatively set as the second color and the 3rd color along two the second sub-pixels 322,324 that second direction is adjacent.It should be noted that, " adjacent " herein does not refer to that two the second sub-pixels 322,324 are interconnected, but represents the second nearest sub-pixel.
3rd sub-pixel 323 has the 4th color.And second direction is vertical with first direction.
It should be noted that, in the description after Fig. 3 and the application, same shape represents same class sub-pixel, and same shade represents same color.In figure 3, each first sub-pixel 311 has identical color; Any two adjacent the second sub-pixels (322 and 324,322 and 325) have mutually different color; Each 3rd sub-pixel 323 has identical color.
In addition, the shape of each sub-pixel shown in Fig. 3 is only schematic.In actual application, the shape of each sub-pixel can be designed as the case may be to meet concrete demand.
In addition, although the first direction shown in Fig. 3 is vertical direction, second direction is horizontal direction.But horizontal direction and vertical direction are only schematic, as long as first direction and second direction meet orthogonal relation, within the protection domain being just considered as fall into the present embodiment.

Then, in step 820, the brightness value obtaining each sub-pixel in intermediate pixel array based on original array forms intermediate luminance array, and intermediate pixel array comprises four color pixel groups, four color pixel groups and the three-color pixel group one_to_one corresponding of the arrangement of multiple matrix.
Such as, intermediate pixel array can comprise the RGBW pixel groups of multiple matrix arrangement.After the brightness value obtaining each sub-pixel in intermediate pixel array, an intermediate luminance array [X corresponding with the brightness value of each sub-pixel in intermediate pixel array can be formed

Then, in step 830, based on the brightness center of original pixel array, from the pel array of dot structure as above, display unit is determined.
In each pixel groups of original pixel array, all there is a brightness center.Such as, if original pixels group is rgb pixel group, so, because the brightness of G sub-pixel is higher than R sub-pixel and B sub-pixel, the brightness of this pixel groups is centrally located at the geometric center of G sub-pixel.In order to ensure that the display effect of dot structure disclosed in the embodiment of the present application is identical with the display effect with RealRGB (true RGB) pel array, the pel array of dot structure disclosed in the embodiment of the present application, should have the brightness center identical with RealRGB pel array.In other words, the quantity at the brightness center that the pel array of dot structure disclosed in the embodiment of the present application has and arrangement mode are all identical with arrangement mode with the quantity at the brightness center of RealRGB pel array.In other words, when original pixel array comprises m × n brightness center O '
ijtime, the pel array in the dot structure of the present embodiment comprises m × n brightness center O
ij.
Determine brightness center in pel array after, just can choose display unit based on the position at this brightness center.Here, display unit has different physical significances from pixel cell each in RealRGB.In RealRGB, be separate between each pixel cell.And between each adjacent display cell, there is the sub-pixel that a part shares mutually.

In fig .9, the empty frame of each broken line closed all represents a display unit.In other words, each display unit comprises the 3rd sub-pixel, two adjacent with the 4th sub-pixel in a first direction the first sub-pixels, and two adjacent with the 3rd sub-pixel in a second direction the second sub-pixels.Two display units adjacent along first direction share first sub-pixel, and two display units adjacent along second direction share second sub-pixel.
In addition, each display unit all comprises a brightness center O
ij, brightness is centrally located at the geometric center of the 3rd sub-pixel of this display unit.
As shown in Figure 9, two display units 910,930 adjacent along first direction share one first sub-pixel 91, and two display units 910,920 adjacent along second direction share one second sub-pixel 92.
Here, it should be noted that, the structure of the display unit shown in Fig. 9 and shared relation are only schematic, in actual applications, can choose the structure of display unit according to real needs and determine the shared relation between each display unit.
In addition, although some of them sub-pixel is divided into several part by the broken line in Fig. 9, which is only schematic.In actual applications, each sub-pixel that each display unit comprises is whole sub-pixel, but not a wherein part for certain sub-pixel.
Referring back to Fig. 8, in step 840, based on the brightness value of each sub-pixel in intermediate pixel array, determine the brightness value of each sub-pixel in display unit.
Due in each display unit that the pel array of the dot structure of the embodiment of the present application comprises, each adjacent display unit has the sub-pixel that a part shares, thus in order to reach the display effect of the RealRGB as original pixel array, need the sub-pixel for each display unit to carry out luminance distribution (namely sub-pixel is played up), thus reach the display effect of RealRGB.
Such as, first original brightness array [X can be passed through
