Detailed description of the invention
The pel array provided in the embodiment of the present invention and the display device including this pel array
Preparation method, can be based on conventional pixel configuration on the basis of, by sub-picture identical for glow color
Element integrates, to constitute a sub-pixel unit, and make each sub-pixel all can and its
The sub-pixel of his glow color is configured to the pixel of luminescence, and then makes preparing this pixel battle array
During row, the sub-pixel that the glow color that integrates is identical can use same mask plate perforate
Carry out evaporation to be formed, while the alignment precision requirement when pel array is prepared in reduction, significantly
The technology difficulty of mask plate is prepared in reduction, can effectively improve the yield of product, reduces technique and becomes
This.
To the pel array of the present invention and this pixel is included below in conjunction with the accompanying drawings with specific embodiment
The preparation method of the display device of array is described in detail.
Fig. 1 be the embodiment of the present invention pel array in the structural representation of pixel cell；Such as figure
Shown in 1, the pel array in the application includes the pixel cell being arranged in order, and each pixel
Unit may each comprise three be disposed adjacent and sub-pixel unit that glow color is different, such as this picture
Element unit can include launching the first pixel cell 1 of HONGGUANG, launching the second pixel cell of green glow
2 and launch the 3rd pixel cell 3 of blue light, and first above-mentioned pixel cell the 1, second picture
Element unit 2 and the 3rd pixel cell 3 all can be white to form a transmitting as a sub-pixel
The pixel of light.
It should be noted that first above-mentioned pixel cell the 1, second pixel cell 2 and
The glow color of three pixel cells 3 can set according to concrete process requirements, if its color
The different pixel that can form a transmitting white light.
Fig. 2 is the structural representation of a pixel cell in Fig. 1, clear in order to show in this Fig. 2
Chu understands, being removed by the Fill Color in each pixel cell figure, the most same icon refers to
It all refers to identical device architecture to show position；Preferably, as in figure 2 it is shown, above-mentioned
One pixel cell 1 can be that the length of side is equal and interior angle is the hexagon of 120 °；Second pixel list
Unit 2 also be that the length of side is equal and the hexagon of evagination, and an opposite side of this second pixel cell 2 is flat
Angle between the hypotenuse that two capable and parallel limits are adjacent is 150 °, and hypotenuse it
Between angle be then 60 °；3rd pixel cell 3 is square, and its length of side is with above-mentioned
The length of side of the first pixel cell 1 and the second pixel cell 2 is the most equal.Arbitrary 3rd pixel cell
One first pixel cell is adjoined respectively on the 3 one each limits of opposite side, and the 3rd pixel cell 3
Adjoin one second pixel cell on each limit of another opposite side the most respectively, and adjacent pixel cell it
Between adjacent limit fit like a glove, to constitute as an overall pel array.
Further, the first above-mentioned pixel cell the 1, second pixel cell 2 and the 3rd picture
Any pixel unit in element unit 3 the most at least includes that two sub-pixels are (such as each pixel list
Unit can arrange the adjacent sub-pixels such as two or four, specifically can be according to the display device of preparation
Resolution requirement set, and in pel array, each sub-pixel is all adjacent has other luminous
Sub-pixel in other pixel cells of color), and each sub-pixel all can be adjacent its
The sub-pixel of his glow color constitutes a pixel that can launch white light.
The application additionally provides a kind of method preparing display device: first, it is provided that if having
The mask plate of dry opening；Use evaporation process, utilize above-mentioned mask plate to prepare as in Fig. 1～2
Shown picture element array structure, and above-mentioned each perforate is used equally to prepare a pixel list
Unit；The most each first the most corresponding interior angle of pixel cell 1 is the length of side of 120 °
Equal hexagon, each second pixel cell 2 then the most corresponding interior angle is respectively 150 °
Each 3rd pixel cell 3 is then pros with the hexagon of the equilateral evagination of 60 °
In shape, i.e. this mask plate, the opening figure of each pixel cell structure can set shown in corresponding diagram 2
Put, thus in above-mentioned evaporation process, if the perforate one_to_one corresponding of each pixel cell
, owing to its size is each sub-pixel unit N (N >=2, and N be positive integer) times,
And then the required precision of alignment is substantially reduced, the most also make the difficulty of the mask plate of preparation
It is greatly reduced (this is because the bore size of mask plate its difficulty prepared the least is the highest).
The most just according to the demand that display device is different to resolution, to the structure shown in Fig. 3～8

And then equilateral hexagons the second sub-pixel unit 2 is divided into four identical (shapes
And length, area, material etc. are the most identical) tool rectangular the first trapezoidal sub-pixel
21、22、23、24；And then make that the sub-pixel periphery of above-mentioned formation is all adjacent has other luminous
The sub-pixel of color, such as, be provided with the first sub-pixel 12 in the 3rd sub-pixel 31 peripheral adjacent
With the second sub-pixel 23, owing to these three sub-pixels are able to launch HONGGUANG, green glow and indigo plant
Light, and then so that it can constitute a dot structure launching white light.
In the present embodiment three, owing to each sub-pixel unit all includes 4 sub-pixels, and then
The resolution making the display device that its pel array constituted formed is above embodiment one He
The resolution of the display device that embodiment two is constituted, but it still can use same mask plate to enter
Row preparation, it may be assumed that
First, it is provided that one is provided with the mask plate of some perforates；Shown in Fig. 2～8, these are some opens
Hole include with the first corresponding first perforate of sub-pixel unit 1 shape, with second as son element single

The dot structure of light.
As it is shown in figure 9, when needs show a white point in pel array, first can be made
Sub-pixel the 12, second sub-pixel 23 and the 3rd sub-pixel for emitting light being adjacent, due to this three
The light of individual sub-pixel emissive is respectively HONGGUANG, green glow and blue light, i.e. this three and collectively forms one
The pixel (i.e. white space shown in Fig. 9) of white light can be launched.
When needs show a white horizontal line, show associated description during white point based on Fig. 9, can
Select to be positioned at the transversely arranged some pixels of same straight line and carry out luminescence, and then formed such as Figure 10
Shown white horizontal line (i.e. white space shown in Figure 10).
Same, when needs show a white vertical line, it is possible to when showing white point based on Fig. 9
Associated description, selects the some pixels being positioned at same straight line longitudinal arrangement to carry out luminescence, and then shape
Become white horizontal line (i.e. white space shown in Figure 11) as shown in figure 11.
In sum, in the above embodiment of the present invention, can be based on conventional pixel array arrangement side
On the basis of formula (such as pentile arrangement mode etc.), by by the sub-picture of identical glow color
Element is integrated into a sub-pixel unit, on the basis of not affecting pel array luminescence, and can be in system
Standby technique utilize a mask plate perforate can form a sub-pixel unit, and then effectively
While reducing the difficulty of making mask plate, moreover it is possible to be substantially reduced in pel array preparation technology
Required precision, and the display device formed also can meet the requirement of resolution, i.e. by one
Mask plate perforate forms multiple sub-pixel being disposed adjacent, and can effectively reduce technology difficulty, carry
The yield of high device, reduces process costs.
