Specific embodiment
The feature and exemplary embodiment of various aspects of the invention is described more fully below.In following detailed description
In, many details are proposed, in order to provide complete understanding of the present invention.
The present invention provides a kind of pixel arrangement structure, display panel and display device, can be used for making PAD or mobile phone etc.
The display screen of electronic equipment can be improved the space utilization rate of pixel by rationally designing to pixel arrangement structure, thus
The PPI for improving display panel, so that picture seems to be more clear.
Fig. 1 is that the schematic diagram for the display panel pixel arrangement that first embodiment of the invention provides (illustrates only part
Dot structure).As shown in Figure 1, display panel includes the repetitive unit 100 of multiple rectangles of array arrangement, each repetitive unit
100 include color different the first sub-pixel, the second sub-pixel and third sub-pixel.First sub-pixel, the second sub-pixel and
The quantity of three sub-pixels is 1:2:2 than meeting.
Wherein, the first sub-pixel is quadrangle, the first sub-pixel is placed in the middle in each repetitive unit 100, the second sub-pixel and
Third sub-pixel is distributed around the first sub-pixel.Dash area in Fig. 1 is schematically divided into 4 sub-regions, makees respectively
For the corresponding region of two the second sub-pixels and two third sub-pixels.Those skilled in the art can close according to actual needs
Reason ground divides the corresponding region of two the second sub-pixels and two third sub-pixels, herein without limiting.
In actual use, it can be realized by matching above-mentioned pixel arrangement structure with corresponding pixel-driving circuit
Two the second sub-pixels and two third sub-pixels share the display effect of the first sub-pixel.
In embodiments of the present invention, each rectangle repetitive unit includes the first different sub-pixel of color, the second sub-pixel
With third sub-pixel, the first sub-pixel, the second sub-pixel, third sub-pixel quantity ratio be 1:2:2, wherein the first sub-pixel
For quadrangle, positioned at the middle part of repetitive unit, the second sub-pixel and third sub-pixel are distributed around the first sub-pixel, therefore, weight
Multiple second sub-pixels and multiple third sub-pixels in multiple unit can realize multiple pixel lists based on the first sub-pixel is shared
Member, for example, 2 the second sub-pixels and 2 third sub-pixels can form 2 pixel lists based on 1 the first sub-pixel is shared
Member improves the PPI of display panel to improve the space utilization rate in repetitive unit.
In addition, compared with multiple sub-pixels are only in arrangement mode transversely or longitudinally, due in the embodiment of the present invention
Repetitive unit uses centered on the first sub-pixel, and the second sub-pixel and third sub-pixel are around the arrangement mode being distributed, therefore,
The shapes and sizes of other sub-pixels can be changed according to the shapes and sizes of the first sub-pixel, to reduce adjacent subpixels
Gap, further increase the space utilization rate in repetitive unit, and can be avoided the display effect for jagged edge occur.
It should be noted that being each formed with micro gap between adjacent subpixels in Fig. 1, it is contemplated that the gap will not
The display effect of each sub-pixel is influenced, whole resolution will not be influenced, omits the signal to micro gap part.
It further, is the space utilization rate in raising repetitive unit, the first sub-pixel, two the second sub-pixels and two
The sum of area of third sub-pixel should be as far as possible close to the area of entire repetitive unit.
In each pixel unit of the embodiment of the present invention, the first sub-pixel, the second sub-pixel and third sub-pixel shine
Color can be respectively red (R), green (G), any one in blue (B).
Preferably, the first sub-pixel can be B sub-pixel, since the luminous efficiency of blue emitting material and service life are minimum, B
The area of sub-pixel can be greater than the area of R sub-pixel and G sub-pixel.
Below with the first sub-pixel for B sub-pixel, the second sub-pixel is R sub-pixel, and third sub-pixel is that G sub-pixel is
The second sub-pixel and third sub-pixel are described in detail around the mode of the first sub-pixel distribution for example.

Two R sub-pixels or two G sub-pixel alignment in repetitive unit 100 and 112.
For entire display panel, the repetitive unit in even column can be revolved relative to the repetitive unit in odd column
It turn 90 degrees, so that two R sub-pixels of adjacent repeat unit or two G sub-pixels is shared a Mask in vapor deposition and open
Mouthful, so as to reduce Mask technology difficulty, make R sub-pixel or G sub-pixel not by under mask plate opening area specification
The limitation of limit.
Fig. 9 is that the schematic diagram for the display panel pixel arrangement that ninth embodiment of the invention provides (illustrates only part
Dot structure).As shown in figure 9, repetitive unit 112 has rotated 90 degree (including left-handed and dextrorotation) relative to repetitive unit 100, weight
Multiple unit 121 has rotated 90 degree (including left-handed and dextrorotation) relative to repetitive unit 100, and repetitive unit 121 is single relative to repeating
Member 100 does not rotate, makes four R sub-pixels or four G sub-pixel alignment in repetitive unit 100,112,121 and 122.
For entire display panel, it can will be in the repetitive unit of even column odd-numbered line, and odd in even number line
The repetitive unit of ordered series of numbers, the initial repetitive unit 100 relative to (1,1) position are rotated by 90 °, adjacent to repeat list after rotation arrangement
The four R sub-pixels or four G sub-pixels of member are arranged in a square, and can share one in vapor deposition in this way has just
The Mask of square structure is open, to further decrease Mask technology difficulty, makes R sub-pixel or G sub-pixel not by for covering
