The arbitrary and all combination of list of items.
One embodiment provides a kind of OLED display screen.The OLED display screen includes OLED pixel structure.Wherein, the OLED
Dot structure is to insert extra sub-pixel on the basis of dot structure shown in Fig. 7 to put forward high-resolution effect so as to reach.Tool
Body realization principle is as follows.
As shown in Figure 1 and Figure 2, OLED pixel structure includes some row pixel cell groups 100.Each pixel cell group 100 includes
It is repeated in some pixel cells 110 of arrangement.It should be noted that Fig. 1 is only a kind of example of OLED pixel structure, its
In, pixel cell group 100 and the number with the pixel cell 110 included altogether in one-row pixels unit group 100 are not limited to Fig. 1 institutes
A kind of situation shown.
Meanwhile each pixel cell 110 includes 113, two the first sub-pixels 111 of the 3rd sub-pixel group and two the second sub- pictures
Element 112.The color of 3rd sub-pixel group 113, the first sub-pixel 111 and the second sub-pixel 112 is different.With reference to Fig. 2, each
In pixel cell 110, a line of one pair of which the first sub-pixel 111 and the second sub-pixel 112 along the 3rd sub-pixel group 113
Form a line, and combine the 3rd sub-pixel group 113 and form a colour element 120.Of the first sub-pixel of another pair 111 and second
Article 2 side of the pixel 112 along the 3rd sub-pixel group 113 forms a line, and combines the 3rd sub-pixel group 113 and form another coloured silk
Color pixel 120.
Wherein, colour element 120 refers to that by what R sub-pixels, G sub-pixel, B sub-pixels were formed a variety of colors can be shown
Pixel.Therefore, the first sub-pixel 111, the second sub-pixel 112, the color of the 3rd sub-pixel group 113 are sub with R sub-pixels, G respectively
Pixel, B sub-pixels one kind therein are identical.In addition, a line of the 3rd sub-pixel group 113 and Article 2 side are put down with arranging
OK, and the relative two articles of sides of respectively the 3rd sub-pixel group 113, so that two pair of first sub-pixel of sub-pixel 111 and second
112 form a line respectively in the both sides of the 3rd sub-pixel group 113.In the present embodiment, adjacent two the first sub-pixels 111 utilize
Same opening is deposited, and is separated two sub-pixels by anode pattern.Two adjacent the second sub-pixels 112 are same
It is deposited using same opening, and is separated two sub-pixels by anode pattern.
In addition, the shape of the first sub-pixel 111, the second sub-pixel 112 and the 3rd sub-pixel group 113 is rectangle, so as to
It is easy to be arranged in a manner of row, column.It is understood that the first sub-pixel 111, the second sub-pixel 112 and the 3rd sub- picture
The shape of element group 113 is not limited to a kind of situation of rectangle, is also possible to make corresponding deformation in actual applications, such as rectangle is fallen
Angle is set, so that four angles of rectangle have certain radian.
Therefore, in above-mentioned OLED pixel structure, 110 need of each pixel cell by two the first sub-pixels 111,
Two the second sub-pixels 112 and the 3rd sub-pixel group 113 may make up two colour elements 120, and in conventional pixel configuration,
It is generally necessary to which two R sub-pixels, two G sub-pixels, two B sub-pixels just may make up 2 colour elements, therefore the present embodiment carries
The OLED pixel structure of confession can improve resolution ratio.
Specifically, the area of the 3rd sub-pixel group 113 is respectively greater than the first sub-pixel 111, the face of the second sub-pixel 112
Product, consequently facilitating making two pair of first sub-pixel 111, the second sub-pixel 112 be in adjacent shape with the 3rd sub-pixel group 113 respectively
State, and form corresponding colour element 120 with the 3rd sub-pixel group 113 respectively.Meanwhile the 3rd sub-pixel group 113 in column direction
Length be respectively greater than the first sub-pixel 111, the second sub-pixel 112 column direction length.Therefore, for any to the first son
For pixel 111, the second sub-pixel 112, the first sub-pixel 111 and the second sub-pixel 112 can be with the 3rd sub-pixel groups 113
In adjacent state, so that the first sub-pixel 111, the second sub-pixel 112, the 3rd sub-pixel group 113 are in immediate shape
State, so as to improve the effect for being mixed into colour.
In addition, in each pixel cell 110, the 3rd sub-pixel group 113 includes a sub-pixel, and the 3rd sub-pixel group
113 are shared by two pair of first sub-pixel 112 of sub-pixel 111 and second.Therefore, in a pixel cell 110, one is used
Three sub-pixel groups 113 and by way of multiplexing, i.e., two couples the first sub-pixel 111, the structure of the second sub-pixel 112 that can be with both sides
Into two colour elements 120.Therefore, the pixel arrangement structure will can at least divide for the dot structure shown in Fig. 7
Resolution improves 4/3 times.
It is understood that the structure setting side of the first sub-pixel 111, the second sub-pixel 112 and the 3rd sub-pixel group 113
Formula is not limited to a kind of above-mentioned situation, as long as can form each pixel cell 110 by way of being multiplexed the 3rd sub-pixel group 113
Two colour elements 120.
Further, as shown in figure 3, the first sub-pixel 111 of the first sub-pixel 111 of any row and adjacent lines is along row side
To Heterogeneous Permutation.Second sub-pixel 112 of any row and the second sub-pixel 112 of adjacent lines are along line direction Heterogeneous Permutation.It is any
3rd sub-pixel group 113 of capable 3rd sub-pixel group 113 and adjacent lines is along line direction Heterogeneous Permutation.Wherein, it is dislocation arrangement,
Refer to not line up in vertical direction (i.e. column direction).Therefore, can be by odd-line pixels unit group 100 relative to even rows
(i.e. line direction) translates certain distance to unit group 100 to the left or to the right in the horizontal direction, or by even rows unit group 100
Relative to odd-line pixels unit group 100, (i.e. line direction) translates certain distance to the left or to the right in the horizontal direction, so as in mistake
Position arrangement mode.
The mode of above-mentioned Heterogeneous Permutation, expand between adjacent first sub-pixel 111, between adjacent second sub-pixel 112,
The distance between adjacent 3rd sub-pixel group 113, under the conditions of same process, it is possible to produce smaller pixel cell
110, further increase resolution ratio.
Specifically, in each pixel cell 110, the arrangement mode phase of two pair of first sub-pixel 112 of sub-pixel 111 and second
Together.Because every a pair of first sub-pixels 111 and the second sub-pixel 112 are arranged in a manner of row, therefore one-row pixels list in office
In tuple 100, the first sub-pixel 111 is respectively positioned on the top of the second sub-pixel 112, or the first sub-pixel 111 is respectively positioned on second
The lower section of sub-pixel 112.
So, based on above-mentioned arrangement mode, each first sub-pixel 111 and adjacent lines in any row pixel cell group 100
The second sub-pixel 112 between each first sub-pixel 111 in pixel cell group 100 be present.Meanwhile any row pixel cell group
Have first between each second sub-pixel 112 in each second sub-pixel 112 and adjacent lines pixel cell group 100 in 100
Sub-pixel 111.Therefore in whole OLED pixel structure, have one between immediate two the first sub-pixels 111 of line direction
Individual 3rd sub-pixel group 113, and second sub-pixel be present between immediate two the first sub-pixels 111 of column direction
112, therefore the distance between each first sub-pixel 111 is larger.Second sub-pixel 112 similarly, i.e., each second sub-pixel 112 it
Between distance it is also larger.Therefore, based on the larger advantage in the interval between the first sub-pixel 111, the second sub-pixel 112, it is more easy to
In producing smaller pixel cell 110.
Further, for the 3rd sub-pixel group 113, the present embodiment takes following measures to increase each 3rd son
Spacing between pixel groups 113.The 3rd sub-pixel group 113 in odd-line pixels unit group 100 is relative to even rows list
The 3rd sub-pixel group 113 in tuple 100 arranges along the distance of line direction translation first, or in even rows unit group 100
The 3rd sub-pixel group 113 relative to the 3rd sub-pixel group 113 in odd-line pixels unit group 100 along line direction translate first
Distance arrangement.Wherein, the first distance is equal in colleague's pixel cell group 100 between the two neighboring center of 3rd sub-pixel group 113
The half of distance.Therefore, each 3rd sub-pixel group 113 in any row pixel cell group 100 is respectively positioned on adjacent lines pixel cell
On vertical center line in group 100 between immediate two the 3rd sub-pixel groups 113.
Therefore, above-mentioned dot structure causes the 3rd sub-pixel group 113 and neighbouring even-numbered in odd-line pixels unit group 100
The distance between the 3rd sub-pixel group 113 in row pixel cell group 100, which is realized, to be maximized, so as to meet the feelings of process conditions
The size of pixel cell 110 can be accomplished to minimize under condition, to be put into greater number in the certain OLED display screen of area
Pixel cell 110, and then meet high-resolution demand.
It is understood that the arrangement mode of adjacent rows pixel cell group 100 is not limited to a kind of above-mentioned situation, as long as energy
Enough improve resolution ratio.For example, in pixel cell 110 two pair of first sub-pixel 112 of sub-pixel 111 and second arrangement mode
Opposite direction is may be alternatively provided as, while different pixels unit 110 is sub by the first sub-pixel 111 and second according to location
Pixel 112 is arranged to corresponding different arrangement mode, so that the distance between each first sub-pixel 111 in OLED pixel structure,
The distance between each second sub-pixel 112 meets the needs of resolution ratio.
Specifically, the color of the 3rd sub-pixel group 113 is blueness, therefore in the present embodiment, the 3rd sub-pixel group 113 is
For blue (B) sub-pixel.So the first sub-pixel 111, the second sub-pixel 112 are respectively then red (R) sub-pixel, green (G)
Sub-pixel is respectively green (G) sub-pixel, red (R) sub-pixel.
Another embodiment provides another OLED pixel structure, and the OLED pixel structure can equally improve resolution ratio.
As shown in Figure 4, Figure 5.
OLED pixel structure includes some row pixel cell groups 200.Each pixel cell group 200 includes being repeated in arrangement
Some pixel cells 210.It should be noted that in Fig. 4 be only OLED pixel structure a kind of example, pixel cell group 200
And it is not limited to a kind of situation shown in Fig. 4 with the number of the pixel cell 210 included altogether in one-row pixels unit group 200.
Meanwhile each pixel cell 210 includes the 3rd sub-pixel group, two the first sub-pixels 211 and two the second sub-pixels
212.The color of 3rd sub-pixel group, the first sub-pixel 211 and the second sub-pixel 212 is different.With reference to Fig. 5, in each pixel
In unit 210, a line of one pair of which the first sub-pixel 211 and the second sub-pixel 212 along the 3rd sub-pixel group lines up one
Row, and combine the 3rd sub-pixel group and form a colour element 220.Another pair the first sub-pixel 211 and the edge of the second sub-pixel 212
The Article 2 side of 3rd sub-pixel group forms a line, and forms another colour element 220 with reference to the 3rd sub-pixel group.
Wherein, colour element 220 refers to that by what R sub-pixels, G sub-pixel, B sub-pixels were formed a variety of colors can be shown
Pixel.Therefore, the first sub-pixel 211, the second sub-pixel 212, the 3rd sub-pixel group color respectively with R sub-pixels, G pictures
Element, B sub-pixels one kind therein are identical.In addition, a line of the 3rd sub-pixel group and Article 2 side are parallel with column direction,
And two articles of sides that respectively the 3rd sub-pixel group is relative, so that two pair of first sub-pixel 212 of sub-pixel 211 and second is
The both sides of three sub-pixel groups form a line respectively.
In addition, the first sub-pixel 211, the second sub-pixel 212 and the 3rd sub-pixel group are shaped as rectangle, consequently facilitating with
The mode of row, column is arranged.It is understood that the first sub-pixel 211, the second sub-pixel 212 and the 3rd sub-pixel group
Shape is not limited to a kind of situation of rectangle, is also possible to make corresponding deformation in actual applications, such as rectangle is carried out into chamfering setting, from
And make four angles of rectangle that there is certain radian.
Therefore, in above-mentioned OLED pixel structure, 210 need of each pixel list pass through two the first sub-pixels 211, two
Individual second sub-pixel 212 and the 3rd sub-pixel group may make up two colour elements 220, and in conventional pixel configuration,
Two R sub-pixels, two G sub-pixels, two B sub-pixels are needed just to may make up 2 colour elements, therefore the present embodiment provides
OLED pixel structure can improve resolution ratio.
Specifically, in each pixel cell 210, the 3rd sub-pixel group include first module 214 and second unit 215 this two
Individual sub-pixel.Meanwhile first module 214 forms a color images with one pair of which the first sub-pixel 211 and the second sub-pixel 212
Element 220.Second unit 215 forms another colour element 220 with another pair the first sub-pixel 211 and the second sub-pixel 212.
Therefore, compared with the dot structure shown in Fig. 1, although the 3rd sub-pixel group in the present embodiment is not multiplexed,
Due to the 3rd sub-pixel group is split as into the less first module 214 of two areas and second unit 215, that is, reduce color images
Area shared by element 220, so as to form greater number of colour element 220 in the limited area of OLED display screen,
Improve resolution ratio.Meanwhile compared with the dot structure shown in Fig. 7, resolution ratio can at least improve 4/3.
In the present embodiment, adjacent two the first sub-pixels 211 are deposited using same opening, and pass through anode pattern
Change separates two sub-pixels.Two adjacent the second sub-pixels 212 are deposited also with same opening, and pass through anode
Graphically two sub-pixels are separated.Adjacent first module 214 and second unit 215 are also deposited using same opening,
And two sub-pixels are separated by anode pattern.
Further, first module 214 and second unit 215 are arranged in a manner of row, equivalent to by the 3rd sub-pixel group
It is two parts along the line segmentation parallel with row.Meanwhile in each pixel cell 210, first module 214 and one pair of which first
The line of centres of the sub-pixel 212 of sub-pixel 211 and second forms virtual triangle.Second unit 215 and of another pair first
The line of centres of the sub-pixel 212 of pixel 211 and second forms virtual triangle.
It should be noted that first module 214 and a pair of first sub-pixels 211 and the second sub- picture positioned at right side in Fig. 5
The composition colour element 220 of element 212, and second unit 215 and a pair of first sub-pixels 211 and the second sub-pixel positioned at left side
212 form colour element 220.Other modes can also be taken to form colour element 220, such as first module 214 with being located at
A pair of first sub-pixels 211 in left side and the second sub-pixel 212 form colour element 220, and second unit 215 is with being located at right side
Another pair the first sub-pixel 211 and the second sub-pixel 212 form colour element 220.
It is understood that the structure setting mode of the first sub-pixel 211, the second sub-pixel 212 and the 3rd sub-pixel group
A kind of above-mentioned situation is not limited to, as long as resolution ratio can be improved by reducing the area of colour element 220.
Further, as shown in fig. 6, the first sub-pixel 211 of the first sub-pixel 211 of any row and adjacent lines is along row side
To Heterogeneous Permutation.Second sub-pixel 212 of any row and the second sub-pixel 212 of adjacent lines are along line direction Heterogeneous Permutation.It is any
Capable the 3rd sub-pixel group and the 3rd sub-pixel group of adjacent lines are along line direction Heterogeneous Permutation.Wherein, it is dislocation arrangement, refers to
Vertical direction (i.e. column direction) does not line up.Therefore, can be by odd-line pixels unit group 200 relative to even rows unit group
200 in the horizontal direction (i.e. line direction) translate certain distance to the left or to the right, or by even rows unit group 200 relative to
(i.e. line direction) translates certain distance to odd-line pixels unit group 200 to the left or to the right in the horizontal direction, so as to be dislocation arrangement
Mode.
The mode of above-mentioned Heterogeneous Permutation, expand between adjacent first sub-pixel 211, between adjacent second sub-pixel 212,
The distance between adjacent 3rd sub-pixel group, under the conditions of same process, it is possible to produce smaller pixel cell 210,
Further increase resolution ratio.
Specifically, in each pixel cell 210, the arrangement mode phase of two pair of first sub-pixel 212 of sub-pixel 211 and second
Together.Because every a pair of first sub-pixels 211 and the second sub-pixel 212 are arranged in a manner of row, therefore one-row pixels list in office
In tuple 200, the first sub-pixel 211 is respectively positioned on the top of the second sub-pixel 212, or the first sub-pixel 211 is respectively positioned on second
The lower section of sub-pixel 212.
So, based on above-mentioned arrangement mode, each first sub-pixel 211 and adjacent lines in any row pixel cell group 200
The second sub-pixel 212 between each first sub-pixel 211 in pixel cell group 200 be present.Meanwhile any row pixel cell group
Have first between each second sub-pixel 212 in each second sub-pixel 212 and adjacent lines pixel cell group 200 in 200
Sub-pixel 211.Therefore in whole OLED pixel structure, have one between immediate two the first sub-pixels 211 of line direction
Individual 3rd sub-pixel group, and second sub-pixel 212 between immediate two the first sub-pixels 211 of column direction be present,
Therefore the distance between each first sub-pixel 211 is larger.Second sub-pixel 212 similarly, i.e., between each second sub-pixel 212
Distance is also larger.Therefore, based on the larger advantage in the interval between the first sub-pixel 211, the second sub-pixel 212, it is easier to make
Produce smaller pixel cell 210.
Further, for the 3rd sub-pixel group, the present embodiment takes following measures to increase by the 3rd sub-pixel
Spacing between group.The 3rd sub-pixel group in odd-line pixels unit group 200 is relative in even rows unit group 200
3rd sub-pixel group arranges along the distance of line direction translation first, or the 3rd sub-pixel group in even rows unit group 200
Arranged relative to the 3rd sub-pixel group in odd-line pixels unit group 200 along the distance of line direction translation first.Wherein, first away from
