Structure schematic diagram, it is cheer and bright also for showing in the Fig. 8, also the Fill Color in each pixel unit figure is removed, i.e., together
It also all refers to identical device architecture at the icon indicating positions of sample；As shown in Fig. 7~8, based on knot shown in above-mentioned Fig. 1~6
On the basis of structure, embodiment one and the related elaboration of embodiment two, each sub-pixel unit is divided into four sub-pixels, with
Each sub-pixel is enabled to constitute the pixel of transmitting white light with the sub-pixel of other luminescent colors；Specifically, in this implementation three
In, each pixel unit is made of four sub-pixels, i.e. the first sub-pixel unit includes the first sub-pixel 11,12,13,14,
Second sub-pixel unit includes the second sub-pixel 21,22,23,24, third sub-pixel unit include third sub-pixel 31,32,33,
34。
It is shown in Figure 8, in third sub-pixel unit 3, two third middle lines of square crossing are set (i.e. shown in Fig. 8
The dotted line being set between third sub-pixel 31, third sub-pixel 32, third sub-pixel 33 and third sub-pixel 34), and this two
Middle line is respectively perpendicular on two opposite side of square, and then the third pixel subelement 3 of square is divided into four complete phases
With the third sub-pixel 31,32,33,34 of the square of (shape and length, area, material etc. are identical)；Likewise,
In first sub-pixel unit, be also provided be mutually perpendicular to and crosspoint is overlapped with the first sub-pixel unit central point two first
Middle line (be set to shown in Fig. 8 the first sub-pixel 11, the first sub-pixel 12, the first sub-pixel 13 and the first sub-pixel 14 it
Between dotted line), and first above-mentioned median perpendicular passes through the midpoint on the side adjacent with above-mentioned third sub-pixel unit 3
Place, and then the first sub-pixel unit of equilateral hexagons 1 is divided into four identical (shape and length, area, materials
Deng identical) rectangular the first trapezoidal sub-pixel 11,12,13,14 of tool；Likewise, in the second sub-pixel unit
In, it is also provided with and is mutually perpendicular to and two the second middle lines that crosspoint is overlapped with the second sub-pixel unit central point (i.e. institute in Fig. 8
Show the dotted line being set between the second sub-pixel 21, the second sub-pixel 22, the second sub-pixel 23 and the second sub-pixel 24), and one
The second above-mentioned median perpendicular of item passes through the midpoint on the side adjacent with above-mentioned third sub-pixel unit 3, and then will be equilateral
The second sub-pixel unit of hexagon 2 is divided into four identical (shape and length, area, material etc. are identical)
Has rectangular the first trapezoidal sub-pixel 21,22,23,24；So that the adjoining of the sub-pixel periphery of above-mentioned formation has it
The sub-pixel of his luminescent color, such as 31 peripheral adjacent of third sub-pixel is provided with the first sub-pixel 12 and the second sub-pixel
23, since three sub-pixels are able to transmitting feux rouges, green light and blue light, so that it can constitute a transmitting white light
Dot structure.
In the present embodiment three, since each sub-pixel unit includes 4 sub-pixels, so that the pixel of its composition
The resolution ratio for the display device that array is formed is above the resolution ratio for the display device that embodiment one and embodiment two are constituted, but its
Still it can be prepared using same mask plate, it may be assumed that
Firstly, providing a mask plate for being provided with several apertures；Shown in Fig. 2~8, several apertures include and first son
1 shape of pixel unit corresponds to the first aperture, with second as corresponding second aperture of plain 2 shape of unit of son, with third sub-pixel
3 shape of unit corresponds to third aperture.
Then, it in evaporation process, prepares to form the pixel array knot as shown in Fig. 3~8 using above-mentioned mask plate
Structure, so that being located at setting sub-pixel unit sub-pixel on the same mask plate can be formed simultaneously.
Size due to above-mentioned mask plate aperture relative to single sub-pixel wants greatly more, and then in evaporation process,
Requirement for mask plate alignment precision will reduce very much, and accordingly when preparing mask plate, the difficulty to go into operation also drops
It is much lower.
Further, in order to the technical solution to the application implementation result carry out more in detail illustrate, below just with
For picture element array structure shown in Fig. 7~8, it is illustrated:
In the structure shown in Fig. 7~8, each pixel unit includes four sub-pixels, and each sub-pixel can be with
Its sub-pixel for emitting other color of light abutted constitutes the dot structure of a transmitting white light.
As shown in figure 9, may make first the 12, second son of sub-pixel when needing to show a white point in pixel array
Pixel 23 and the third sub-pixel for emitting light being adjacent, since the light of three sub-pixel emissives is respectively feux rouges, green light and indigo plant
Light, the i.e. three collectively form the pixel (i.e. white space shown in Fig. 9) that can emit white light.
When needing to show a white horizontal line, associated description when white point is shown based on Fig. 9, may be alternatively located at same straight line
Transversely arranged several pixels carry out luminous, and then form white horizontal line (i.e. blank area shown in Figure 10 as shown in Figure 10
Domain).
Likewise, may be based on associated description when Fig. 9 shows white point when needing to show a white vertical line, selecting position
It is carried out in several pixels of same straight line longitudinal arrangement luminous, and then forms white horizontal line (i.e. shown in Figure 11 as shown in figure 11
White space).
In conclusion in the above embodiment of the present invention, it can be based on conventional pixel array arrangement mode (such as pentile row
Column mode etc.) on the basis of, by the way that the sub-pixel of identical luminescent color is integrated into a sub-pixel unit, do not influencing pixel
On the basis of array light-emitting, a sub-pixel unit can be formed using a mask plate aperture in preparation process, in turn
While the difficulty of production mask plate is effectively reduced, moreover it is possible to the required precision in pixel array preparation process is substantially reduced,
And the display device formed is also able to satisfy the requirement of resolution ratio, i.e., forms multiple sons being disposed adjacent by a mask plate aperture
Pixel can effectively reduce technology difficulty, improve the yield of device, reduce process costs.
For a person skilled in the art, after reading above description, various changes and modifications undoubtedly be will be evident.
Therefore, appended claims should regard the whole variations and modifications for covering true intention and range of the invention as.It is weighing
