Embodiment
The explanation of following embodiment is refer to the attached drawing, can be to the specific embodiment implemented to the example present invention.
Refer to shown in Fig. 1, the embodiment of the present invention one provides a kind of pixel arrangement structure of OLED display panel, including：
Multiple first sub-pixels 1, multiple second sub-pixels 2 and multiple 3rd sub-pixels 3, it is the multiple first sub-pixel 1, multiple
Second sub-pixel 2 and multiple 3rd sub-pixels 3 form the virtual octagon of multiple repeated arrangements；
3rd sub-pixel 3 is arranged on the virtual octagonal inside, and each virtual octagonal inside is provided with four
3rd sub-pixel 3, four the 3rd sub-pixels 3 are centrosymmetric arrangement with the virtual octagonal center；
First pixel 1 is spaced apart with the 3rd pixel 3, and with virtual octagonal first apex
The heart；
Second pixel 2 is spaced apart with the pixel 3 of the first pixel 1 and the 3rd, and with it is described virtual octagonal
The center of the second adjacent apex of first summit；
The two neighboring virtual octagon has a common edge.
Specifically, virtual octagon includes eight summits, and adjacent two summit is connected to form on one side, four the first sub-pixels 1
With four the second sub-pixels 2 totally eight sub-pixels respectively on virtual octagonal eight summits, the center of each sub-pixel with
Each summit overlaps.Four the first sub-pixels 1 and four the second sub-pixels 2 are alternately arranged and specifically referred to, the first sub-pixel 1 and second
Sub-pixel 2 is alternately distributed on virtual octagonal each summit, with being the second sub-pixel 2 at the adjacent vertex of the first sub-pixel 1,
Equally, with being the first sub-pixel 1 at the adjacent vertex of the second sub-pixel 2.Include four virtual octagon OC1- shown in Fig. 1 altogether
OC4, as illustrated with the dotted box.
Virtual polygon OC1 and virtual polygon OC2 has a common edge CL1, virtual polygon OC2 and virtual polygon
There is OC3 a common edge CL2, virtual polygon OC3 and virtual polygon OC4 to have a common edge CL3, virtual polygon OC4
There is a common edge CL4 with virtual polygon OC1.The summit at common edge both ends is respectively the first sub-pixel 1 and the second sub-pixel
2, the first sub-pixel 1 and the second sub-pixel 2 at this will be shared by adjacent two virtual octagons, i.e., two adjacent void
Intend octagon includes 14 sub-pixels altogether（7 the first sub-pixels 1 and 7 the second sub-pixels 2）, it is possible thereby to reduce number of sub-pixels
Amount.In each virtual octagon, the first sub-pixel 1, the second sub-pixel 2, the quantity ratio of the 3rd sub-pixel 3 are 1:1:1.
It can further be seen from figure 1 that two neighboring virtual octagon symmetrically arranges using common edge as symmetry axis, for example, empty
Intend polygon OC1 and virtual polygon OC2 using common edge CL1 as symmetry axis symmetric arrays, virtual polygon OC2 and virtual polygonal
Shape OC3 using common edge CL2 as symmetry axis symmetric arrays, virtual polygon OC3 and virtual polygon OC4 using common edge CL3 as pair
Claim axial symmetry arrangement, virtual polygon OC4 and virtual polygon OC1 is using common edge CL4 as symmetry axis symmetric arrays.
Four the 3rd sub-pixels 3 are symmetrical arranged with the virtual octagonal center O, therefore can merge open a FMM
（Fine Metal Mask, fine metal mask plate）Opening, adjacent subpixels are deposited together, reduce FMM manufacture difficulties,
The resolution ratio of panel will not be reduced again simultaneously.
Referring again to shown in Fig. 2, if establishing orthogonal coordinate system as origin using each virtual octagonal center O, it is located at
The first sub-pixel, the second sub-pixel and the 3rd sub-pixel of each quadrant will form base pixel unit.Two phases shown in Fig. 2
Adjacent virtual octagon, coordinate system is established using respective center O as origin, altogether including 8 base pixel unit B P1-BP8, such as
Shown in rectangle frame.Specifically, each base pixel unit includes 1/2 the first sub-pixel, 1,1/2 the second sub-pixel 2,1
3rd sub-pixel 3, the quantity ratio of three sub-pixels is 1/2:1/2:1, namely 1:1:2.In each base pixel unit, first
The sub-pixel 2 of sub-pixel 1 and second only has for 1/2 the reason for be, the first sub-pixel 1 and the second sub-pixel 2 herein are adjacent
Two virtual octagons share, and thus also bring adjacent of two the first sub-pixels of base pixel units shared 1 or second
Pixel 2, for example, base pixel unit B P2 and base pixel unit B P3 shares 1 the first sub-pixel 1, base pixel unit B P2
With being positioned above, unshowned another 1 the second sub-pixel 2 of base pixel units shared, therefore, base pixel unit B P2
Include 1/2 the first sub-pixel, 1,1/2 the second sub-pixel 2 and 1 the 3rd sub-pixel 3 altogether.For another example, base pixel unit B P6
With base pixel unit B P7 share 1 the second sub-pixel 2, base pixel unit B P6 with being disposed below, it is unshowned another
1 the first sub-pixel 1 of base pixel units shared, therefore, base pixel unit B P6 include 1/2 the first sub-pixel 1,1/2 altogether
Individual second sub-pixel 2 and 1 the 3rd sub-pixel 3.Other base pixel units are also same situation.
It should be noted that in the present embodiment, the sub-pixel quantity that each base pixel unit includes is 2.0（1/2
One 2+1 the 3rd sub-pixels 3 of the second sub-pixel of sub-pixel 1+1/2）, shared area is smaller.It is in addition, every in the present embodiment
Though the first sub-pixel 1 and the second sub-pixel 2 are shared in a base pixel unit, the 3rd sub-pixel 3 be it is independent, not with its
His base pixel units shared, therefore more excellent image quality can be brought.
Again as shown in figure 3, the signal of another pixel arrangement structure for a kind of one OLED display panel of the embodiment of the present invention
Figure.Difference compared with the arrangement architecture shown in Fig. 1 is that the adjacent virtual octagon shown in Fig. 3 is adjacent obliquely, Fig. 1
It is shown, it is adjacent in the horizontal direction or on vertical direction, for example, virtual octagon OC5 and virtual octagon OC6 has in Fig. 3
Common edge CL5, it is at an angle with horizontal direction or vertical direction shape（If virtual octagon is octagon, the angle
Spend for 45）.Similarly, the common edge CL6, virtual octagon OC7 that virtual octagon OC6 and virtual octagon OC7 has and void
The common edge CL8 that the common edge CL7, virtual octagon OC8 and virtual octagon OC5 that intending octagon OC8 has have, respectively
It is at an angle with horizontal direction or vertical direction shape.
Virtual octagon shown in Fig. 1-Fig. 3 is octagon, but the embodiment of the present invention is not limited thereto, can be with
It is the non-equilateral octagon with the two Symmetric Orthogonal axles intersected at virtual octagonal center.
Further, the area equation of the first sub-pixel 1, the second sub-pixel 2 and the 3rd sub-pixel 3.
Further, the first sub-pixel 1, the second sub-pixel 2 and the 3rd sub-pixel 3 are three kinds of glow colors of red, green, blue
Any of, and the glow color of the first sub-pixel 1, the second sub-pixel 2 and the 3rd sub-pixel 3 differs.
Corresponding to the embodiment of the present invention one, the embodiment of the present invention two provides a kind of OLED display panel, has such as the present invention
Pixel arrangement structure described in embodiment one.
By described above, the beneficial effect of the embodiment of the present invention is：It is two neighboring virtual octagonal common
First sub-pixel and the second sub-pixel at side both ends are shared by two neighboring virtual octagon, it is possible to reduce sub-pixel quantity,
And make spatial area shared by each base pixel unit smaller；Four the 3rd sub-pixels are located at virtual octagon center, can be with
A FMM opening is shared, evaporation difficulty is reduced, so as to reduce manufacture difficulty, and the 3rd sub- picture in base pixel unit
Element is independent, not with other base pixel units shareds, can bring more excellent image quality, will not reduce the resolution ratio of panel.
Above disclosure is only preferred embodiment of present invention, can not limit the right model of the present invention with this certainly
Enclose, therefore the equivalent variations made according to the claims in the present invention, still belong to the scope that the present invention is covered.
