Preferably, it is identical with the arrangement of all pixels unit in a line, also, each pixel unit is turned over along line direction Arrangement after turnback (itself left and right overturning) is identical as the arrangement of pixel unit adjacent in same row.So One, pixel unit more compact can arrange, and reduce pel spacing, improve PPI.
Here, the pixel unit of the first row first row is denoted as pixel unit (1,1), the pixel unit of the first row secondary series It is denoted as pixel unit (1,2), the pixel unit of the second row first row is denoted as pixel unit (2,1), the pixel of the second row secondary series Unit is denoted as pixel unit (2,2), and so on.As shown in figure 3, the pixel unit (1,1) of the first row first row overturns 180 degree The arrangement of arrangement and the adjacent pixel unit i.e. pixel unit (2,1) of the second row first row afterwards is identical.To, Two pixel units in same repetitive unit, for example, the third sub-pixel phase of pixel unit (1,1) and pixel unit (2,1) Mutually it is staggered arrangement (the third sub-pixel of pixel unit (1,1) and pixel unit (2,1) is not arranged point-blank), because And the vapor deposition opening on the vapor deposition mask plate (FMM) to form third sub-pixel is also the arrangement that is staggered, and can reduce vapor deposition and cover The difficulty of film version manufacture craft and evaporation process.Compared to the sub-pixel pair in adjacent rows pixel unit in Real dot structure Its situation arranged, using the structure of the sub-pixel dislocation arrangement of this adjacent rows, expands in the identical situation of process conditions Utilizable distance between the opening of each identical sub-pixel, it is so as to do the size of pixel unit smaller, favorably In the manufacture for realizing sharpness screen.
First sub-pixel 301, the second sub-pixel 303 and third sub-pixel 305 can it is in the shape of " pin ", fall " product " word Shape, the triangle disposition for rotating to the left 90 degree or rotate to the right 90 degree triangle disposition arrangement, be also possible to it is substantially in the shape of " pin ", Triangle disposition, the triangle disposition for rotating to the left 90 degree of triangle disposition or rotating to the right 90 degree.Arrangement shown in Fig. 3 In, in the pixel unit of odd-numbered line, the first sub-pixel 301, the second sub-pixel 303 and third sub-pixel 305 are in rotate to the right 90 The triangle disposition of degree is arranged, that is, the first sub-pixel 301 and the second sub-pixel 303 are arranged in left side, and third sub-pixel 305 is arranged On right side；In the pixel unit of even number line, the first sub-pixel 301, the second sub-pixel 303 and third sub-pixel 305 are in Xiang Zuoxuan The triangle disposition arrangement turning 90 degrees, that is, third sub-pixel 305 is arranged in left side, the first sub-pixel 301 and the second sub-pixel 303 It is arranged in right side.
Further, point-blank with the first sub-pixel 301 arrangement of all pixels unit in a line, in a line Second sub-pixel 303 of all pixels unit is to arrange point-blank, with the third sub- picture of all pixels unit in a line Element 305 is also to arrange point-blank.
Wherein, each sub-pixel in pixel unit includes luminous zone (viewing area) and non-light-emitting area (non-display area), It include that cathode, anode and electroluminescence layer (organic emission layer), the electroluminescence layer are located in the luminous zone of each sub-pixel Between cathode and anode, for generating predetermined color light to realize display.It usually requires using evaporation process three times with respectively The electroluminescence layer of corresponding color (such as red, green or blue) is formed in the luminous zone of corresponding color pixel region, certainly, If shape is identical with arrangement, the electroluminescence layer of multiple color can also be realized using same mask plate by modes such as deviations Vapor deposition.
First sub-pixel, the second sub-pixel and third sub-pixel by red (R) sub-pixels, green (G) sub-pixels and Blue (B) sub-pixels composition.I.e. in the present embodiment, the first sub-pixel is red (R) sub-pixels, green (G) sub-pixels and indigo plant (B) one of sub-pixels, the second sub-pixel are it in red (R) sub-pixels, green (G) sub-pixels and blue (B) sub-pixels One, third sub-pixel is one of red (R) sub-pixels, green (G) sub-pixels and blue (B) sub-pixels, and the first sub-pixel, The color of second sub-pixel and third sub-pixel is different.For example, first sub-pixel 301 is green in arrangement shown in Fig. 3 Color (G) sub-pixel, the second sub-pixel 303 are red (R) sub-pixel, and third sub-pixel 305 is blue (B) sub-pixel.Correspondingly, First sub-pixel 301 includes the luminous zone G 302 and the non-light-emitting area G, and including the organic emission layer for emitting green light；The Two sub-pixels 303 include the luminous zone R 304 and the non-light-emitting area R, and including the organic emission layer for emitting feux rouges；Third Sub-pixel 305 includes the luminous zone B 306 and the non-light-emitting area B, and including the organic emission layer for emitting blue light.
