The luminescent layer of the Organic Light Emitting Diode of row.Therefore, Fig. 7 mask arrangement is corresponding with the structure of above-mentioned pel array.
For example, the angle in the present embodiment between each first area Rb1 of mask arrangement long side Lb1 and X-direction is θ,
Angle between each second area Rb2 long side Lb2 and X-direction is θ, every one the 3rd region Rb3 long side Lb3 and X-direction
Between angle be 90- θ, wherein θ is more than 0 and less than 90 degree, and the θ of Fig. 6 mask arrangements is the θ phases with above-mentioned pel array
Together.In addition, the ratio between each first area Rb1 long side Lb1 and short side Wb1 is 2:1, each second area Rb2 length
Ratio between side Lb2 and short side Wb2 is 2:1, and the ratio between every one the 3rd region Rb3 long side Lb3 and short side Wb3 is
2:1, but be not limited.For example, the dimension scale of the mask arrangement be can be according to the dimension scale of pel array
It is adjusted, so that both structures are corresponding (such as can be adjusted to corresponding with the pel array of Fig. 6 embodiments).Change speech
It, the first area Rb1 of mask arrangement is the structure setting for the first area R1 that can for example correspond to above-mentioned pel array, second
Region Rb2 is the structure setting for the second area R2 that can for example correspond to above-mentioned pel array, and the 3rd region Rb3 is for example may be used
With the 3rd region R3 of corresponding above-mentioned pel array structure setting.
In the present embodiment, mask arrangement is to form the organic of different colours in pel array for arranging in pairs or groups evaporation process
Layer.Specifically, when red sub-pixel to be formed, the 3rd region Rb3 of mask arrangement patterns of openings Op position is passed through
And red organic layer is formed in corresponding region in a manner of evaporation;Meanwhile first in the first area Rb1 of mask arrangement
The second masking pattern M2 in masking pattern M1 and second area Rb2 can cover other regions.In the same manner, it is other to be formed
The sub-pixel of color, then as described above, patterns of openings Op is formed in the opposed area of the color sub-pixels in alignment with being intended to, and with
The mode of evaporation forms the color sub-pixels.Therefore, the mask arrangement using the present embodiment and the evaporation step by repeating,
The organic layer of the pel array such as above-mentioned Figure 1A, 1B, Fig. 4 A, 4B and Fig. 5 A, 5B can then be formed.
In summary, in pel array of the invention in the first area on substrate, second area and the 3rd region
It is respectively provided with least two first color sub-pixels, at least two second color sub-pixels and at least two the 3rd colors
Pixel, and angle, Yi Ji between angle between the long side and X-direction of first area, the long side of second area and X-direction
Angle between the long side and X-direction in three regions is controlled in certain limit.In addition, first area, second area and
There is contact point between three regions, and it is close in the first color sub-pixels, second area of this contact point in first area
The 3rd color sub-pixels in second color sub-pixels of this contact point and the 3rd region close to this contact point are to form a picture
Plain unit.Therefore, pel array of the present invention makes under the size limitation of fine metal mask.In addition, with traditional
Pixel arrangements are compared, and pel array of the invention can further improve the picture element density (ppi) and resolution ratio of panel.
