It arranges in RGB, RGBG, RGBW or CMYW, wherein R, G, B, C, M, Y, W are respectively red sub-pixel point, green sub-pixels point, indigo plant
Sub-pixels point, cyan sub-pixel point, pinkish red sub-pixels point, yellow sub-pixel point and white sub-pixels point, each sub- picture of colour
Colour is not arranged on white sub-pixels point for the solid colour of the color of colored filter 4 on vegetarian refreshments and each color sub-pixel point
Optical filter 4.RGB arrangement modes are as shown in figure 9, i.e. three R, G, B sub-pixel points are arranged in a minimum weight in horizontal or vertical direction
Multiple unit, namely a pixel is constituted, the sequence of wherein R, G, B are interchangeable, then on the basis of the minimum repetitive unit, along cross
Multiple minimum repetitive units of arranging are repeated to longitudinal.The arrangement mode of RGBG is as shown in figure 8, i.e. four R, G, B, G sub-pixels
The rectangular arrangement of point forms a minimum repetitive unit, namely constitutes a pixel, and two G sub-pixel points are in diagonal line minute
Cloth transversely repeats multiple minimum repetitive units of arranging then on the basis of the minimum repetitive unit with longitudinal.It arranges with RGBG
Mode is similar, and RGBW arrangements are that the rectangular arrangement of the sub- pixels of R, G, B, W tetra- forms a minimum repetitive unit, R, G, B, W
Sequence it is interchangeable, as shown in Figure 3 and Figure 4.CMYW arrangements are then that the rectangular arrangement of the sub- pixels of C, M, Y, W tetra- forms one most
The sequence of small repetitive unit, C, M, Y, W is interchangeable, as shown in Figure 10.
In another preferred embodiment, there is multiple pixels, which part pixel or whole on chromatic display
Pixel is color pixel cell, and each pixel includes 2 to 9 adjacent sub-pixel points 8, corresponding to each color pixel cell
The colored filter of same color is both provided on all sub-pixel points 8, multiple pixels are distributed in matrix form, multiple pixels
Minimum repetitive unit in RGB, RGBG, RGBW or CMYW arrange, wherein R, G, B, C, M, Y, W be respectively red pixel point, it is green
Colour vegetarian refreshments, blue pixel point, cyan pixel point, magenta pixel point, yellow pixel point and white pixel point, white pixel point
Colored filter 4 is not set on corresponding sub-pixel point 8.It, should when each pixel includes two adjacent sub-pixel points 8
Two sub- pixels 8 along display layer 2 transversely or longitudinally distribution, when each pixel includes nine adjacent sub-pixel points 8
When, this nine adjacent sub-pixel points 8 can be in that endian format is distributed.By taking chromatic display shown in Figure 11 as an example, each
Pixel includes the sub-pixel point 8 of four adjacent rectangular distributions, and multiple pixels are distributed in RGBW formulas, each red pixel
Point includes four sub-pixel points 8 for being provided with Red lightscreening plate above, and correspondingly, each green, blue pixel point respectively include
Four are provided with green, blue color filter sub-pixel point 8 above, and white pixel point includes then four and colored filter is not arranged above
The sub-pixel point of mating plate 4.The chromatic display of the embodiment can be applied to the scene of less demanding to pixel precision.
It please refers to Fig.3 to Fig. 6, on the direction of upper surface for being parallel to display layer 2, has between adjacent color optical filter 4
There are gap, display layer 2 to expose from the gap between colored filter 4.When there are one colorized optical filterings for setting on color sub-pixel point 8
When piece 4, there is gap between the colored filter 4 on two neighboring color sub-pixel point 8.It is arranged when on color sub-pixel point 8
When there are multiple colored filters 4, also there is gap between the adjacent color optical filter 4 on the color sub-pixel point 8.
In a preferred embodiment, 2-9 colored filter 4 can be set on each color sub-pixel point 8.Please refer to Fig.3,
Fig. 5 and Fig. 6, when two colored filters 4 are arranged on each color sub-pixel point 8, whens two colored filters 4, can be arranged side by side
Setting, when four colored filters 4 are arranged on each color sub-pixel point 8, four colored filters 4 can be in matrix form point
Cloth, when nine colored filters 4 are arranged on each color sub-pixel point 8, nine colored filters 4 can be in endian format point
Cloth.Due to being provided with multiple colored filters 4 on each color sub-pixel point 8, and between having between adjacent color optical filter 4
Gap, therefore the color that each color sub-pixel point 8 is presented can be made more uniform.
Referring to FIG. 3, each color sub-pixel point 8 includes four rectangle colored filters 4 in matrix form distribution, and four
Gap between a rectangle colored filter 4 forms cross.This arrangement mode can make the color of the color sub-pixel point 8
All more balanced with Luminance Distribution, display effect is preferable.
In a preferred embodiment, the area of the colored filter 4 of each color sub-pixel point 8 and each color sub-pixel point
8 area ratio is 0.13-0.9:1.If the area ratio is too small, the color saturation of chromatic display can be reduced,
If the area ratio is too big, the brightness of chromatic display can be reduced.By area ratio control to 0.13-0.9:1, energy
Ensure that chromatic display has preferable display effect.Preferably, the face of the colored filter 4 of each color sub-pixel point 8
Product and the area ratio of each color sub-pixel point 8 are 0.3-0.8:1.
It please refers to Fig.3, Fig. 5 and Fig. 6, each color sub-pixel point 8 include multiple rectangle colored filters 4, be parallel to
On the direction of the upper surface of display layer 2, there is gap, the length of side (packet of rectangle colored filter 4 between adjacent color optical filter 4
