In display mode in the present example embodiment, the white sub-pixels can be as the bright of the display unit
Degree center.When the default spacing being staggered is 1/2 sub-pixel spacing, it is ensured that brightness center is located in display unit
Heart point.Brightness center be display unit in become clear center, human eye is most strong to the perception at brightness center, can be used for regarding
Display unit is distinguished in feel, the resolution ratio of display panel can usually be defined by calculating the quantity at brightness center.In Fig. 4
It is shown, due to white sub-pixels in the present exemplary embodiment quantity compared with the prior art in standard RGB display devices simultaneously
It does not reduce, therefore under comparable size, the display list that visually can have quantity essentially identical with standard RGB display devices
Member, i.e., can visually have with standard RGB display devices essentially identical PPI (pixels per inch, per inch
Number of pixels).
The display brightness of each sub-pixel can pass through sub-pixel Rendering algorithms (Sub Pixel in above-mentioned display device
Rendering, SPR) it determines.In the present exemplary embodiment, the display device can also include a sub-pixel rendering module, son
Pixel rendering module can be according to sub-pixel Rendering algorithms by each son in corresponding first virtual pixel array of an image to be displayed
The brightness value of pixel is converted to the brightness value of each sub-pixel in the pel array.
With reference to shown in figure 5, in the present exemplary embodiment, first virtual pixel array may include array distribution and
The first virtual display formed by the color sub-pixel of red, green and blue, as image to be displayed data information
Corresponding standard rgb pixel matrix.It is terrible since the pel array in the present exemplary embodiment further includes white sub-pixels
To the transition convenient for brightness transition, one second virtual pixel array can also be provided, including array distribution and by white sub-pixels
And the second virtual display that the color sub-pixel of red, green and blue is formed, can be foregoing standard
RGBW picture element matrixs.As shown in Figure 5, sub-pixel rendering module can be first by each first virtual display neutron picture
The brightness value corresponding conversion of element is the brightness value of each second virtual display sub-pixel；It then, can will be each described
The brightness value of second virtual display sub-pixel is converted to the brightness value of the display unit sub-pixel.It needs to illustrate
It is that, if above-mentioned first virtual pixel matrix is RGBW picture element matrixs, can also be not necessarily to provide the second virtual pixel matrix.
In the present exemplary embodiment, the brightness value corresponding conversion by each first virtual display sub-pixel is each
The brightness value of the second virtual display sub-pixel may comprise steps of：
S1. a white brightness value is extracted from the brightness value of any first virtual display；With y4, y5, y6 group
At the first virtual display for, white brightness value w is：
W=kmin (y4, y5, y6)
Wherein, k is predetermined coefficient, and y4, y5, y6 are the brightness of sub-pixel y4, y5, y6.
S2. the sub- picture in the white brightness value is deducted from the brightness value of each sub-pixel in first virtual display
The part that element is contributed obtains red, green and blue intensity values；For example, after deducting white brightness value w in y4, y5, y6
Brightness be：Y4-w, y5-w and y6-w.
S3. it is virtual aobvious the white brightness value and red, green and blue intensity values to be corresponded to one described second
Show the brightness value of each sub-pixel in unit；For example, the brightness of second obtained virtual display sub-pixel Y5, Y6, Y7, Y8
Value Y5, Y6, Y7, Y8 are respectively：
Y5=α (y4-w)
Y6=α (y5-w)
Y7=α (y6-w)
Y8=w
Wherein, α is conversion factor.
Shown in Fig. 5, wherein in the picture element matrix (Fig. 5 bottoms) provided in this example embodiment,
Each color sub-pixel is shared by four display units, and four display units for as sharing the color sub-pixel respectively correspond to
Second virtual display in the brightness of sub-pixel identical with the color sub-pixel color contribute.Based on this,
It can be superimposed to obtain the brightness value of each color sub-pixel.Such as：
In any display unit, the brightness value of any color sub-pixel is L1：
L1=p (x0l0+x1l1+x2l2+x3l3)；
Wherein, the l0~l3And x0~x3All display units for respectively sharing the color sub-pixel respectively correspond to
Second virtual display in sub-pixel identical with the color sub-pixel color brightness value and wherein by the colour
The brightness ratio that sub-pixel is contributed, p be regulation coefficient and p≤1, regulation coefficient be mainly used for the brightness value to being calculated into
Row decaying, overflows to avoid brightness.
White sub-pixels by other display share, in any display unit, any white sub-pixels it is bright
Angle value L2=qn；Wherein, the n is the bright of white sub-pixels in corresponding second virtual display of the display unit
Angle value, q are regulation coefficient and q≤1, and regulation coefficient is mainly used for decaying to the brightness value being calculated, to avoid brightness
It overflows, meanwhile, regulation coefficient q can be also used for the adjustment of brightness and saturation degree etc. to showing picture.
Since there are four color sub-pixels in a display unit, and include three kinds of colors with reference to shown in figure 5, because
This have a kind of color sub-pixel can there are two, and then in second virtual display, the brightness of part sub-pixel is by picture
A sub-pixel is provided separately in prime matrix, and the brightness of part sub-pixel is provided jointly by two sub-pixels in picture element matrix.Base
In this, in the present exemplary embodiment, if sub-pixel identical with the color sub-pixel color in second virtual display
