As described in background, it is colored aobvious to carry out as primary colours to mostly use greatly three sub-pixels for current display panel
Show, it is especially the most universal using RGB as three primary colours.The colorization method of OLED screen body there are many kind, now it is more mature simultaneously
The OLED colorization technology of a large amount of volume productions is OLED evaporation coating technique, and traditional RGB stripe shape arrangement mode is used to be deposited.Its
In, the mode of display picture effect most preferably juxtaposition (side-by-side), specifically in pixel (Pixel) unit
There are three sub-pixels (sub-pixel) of red, green, blue (R, G, B), each sub-pixel is rectangle, and is respectively had independent
Organic light emission component, it is using evaporation film-forming technology through fine metal mask version (Fine Metal Mask, FMM)
Corresponding location of pixels forms organic light emitting component on array (array) substrate, and the fine metal mask version is usual
Mask plate is referred to as deposited.Make the OLED display screen of high PPI (Pixel Per Inch, the number of pixels that per inch is possessed)
Technology focus on the FMM of tractability and good mechanical stability and the arrangement mode of pixel.Specifically, FMM mask plate
The problems such as warpage, fracture should occur as little as possible, avoids the dizzy defect influences such as opening, deviate and quality is deposited of vapor deposition film layer.
The arrangement mode of pixel is to determine whether FMM is easy to happen warpage and major cause of failure.That is, the arrangement of pixel and sub-pixel
Mode largely determines that the mechanical performance of FMM, the mechanical performance of FMM largely determine the quality of vapor deposition.
Dot structure in the prior art shown in FIG. 1 generallys use FMM shown in Fig. 2 and is deposited, this kind of FMM includes
Blocked area between several vapor depositions opening B and blocked area C, two adjacent vapor deposition opening B of same row is referred to as connecting bridge
(bridge).Since the sub-pixel of same color in the arrangement mode of Fig. 1 is upper and lower contraposition setting, the vapor deposition of FMM is opened
Mouth B must also align setting, this connecting bridge (bridge) that longitudinally adjacent two are deposited between opening B has broken string

100 include the first pixel group 10 and the second pixel group 20 along first direction arranged adjacent.
Each pixel group includes multiple first sub-pixels 1, multiple second sub-pixels 2 and multiple third sub-pixels 3.Specifically
Ground, the first sub-pixel 1, the second sub-pixel 2 and third sub-pixel 3 have different luminescent colors, first the 1, second son of sub-pixel
Pixel 2 and the color of third sub-pixel 3 can be the first color, the second color and third color, the first color, the second color and
Third color is respectively one of red, blue and green, certainly, in some other embodiment, the first sub-pixel 1, the
Two sub-pixels 2 or third sub-pixel 3 can also be other colors except red, blue and green, be not limited thereto.
In each pixel group, multiple first sub-pixels 1 and multiple second sub-pixels 2 are arranged alternately and line of centres shape
At virtual polygon, multiple third sub-pixels 3 are arranged in virtual polygon.In other words, in each pixel group, multiple thirds
Sub-pixel 3 is surrounded by multiple first sub-pixels 1 and 2 institute of multiple second sub-pixels.Wherein, the first son in each pixel group
The quantity ratio of pixel 1, the second sub-pixel 2 and third sub-pixel 3 is 1:1:1, that is to say, that not homochromy in each pixel group
Sub-pixel quantity it is identical, second sub-pixel is equipped between the first sub-pixel of every two, correspondingly, of every two second

Very little pixel unit to increase the PPI of display panel, and then improves the resolution ratio of display panel.At the same time, same picture
Mirror symmetry is arranged in a first direction for the first pixel group 10 and the second pixel group 20 in plain big group 100, to make to appoint
The luminescent color of adjacent sub-pixel is identical in the Liang Ge pixel group for anticipating adjacent, and then can make adjacent two or more same
Sub-pixels share the Mask opening an of mask plate, improve the PPI of display panel.
It may be noted that since the arrangement mode of the first sub-pixel 1 and the second sub-pixel 2 in pixel group is different,
Therefore arrangement mode above-mentioned is used, the Mask that adjacent two or more same sub-pixels can be made to share a mask plate is opened
Mouthful, it is subsequent this to be illustrated with specific embodiment, therefore this will not be repeated here.
It is readily appreciated that, pixel arrangement more evenly, advantageously reduces the manufacture craft difficulty of fine metal mask version and opens
Net difficulty, to improve evaporation effect and production yield.In addition, pixel arrangement is uniformly conducive to improve what pixel unit divided
