In the related art, as shown in fig. 1, a designer may set a first area a and a second area B on an array substrate as shown in fig. 1 according to requirements of different display areas on display effects and light transmission performance, and the pixel densities of the first area a and the second area B are different. However, since the pixel densities of the first area B and the second area B are different, a complete pixel repeating unit cannot be designed for the width of the connecting area between the first area a and the second area B, so that an area which cannot emit light exists between the first area a and the second area B, and for the display panel, the area is shown as a dark line and cannot be used for displaying, so that a display gap is caused, and the display effect is poor.
Based on this, the present application proposes an array substrate as shown in fig. 2 to solve the problem of dark lines in the related art. Specifically, as shown in fig. 2 and 3, the array substrate 100 may include a light emitting layer 101, and the light emitting layer 101 may include a first light emitting region 1, a second light emitting region 2, and a third light emitting region 3, where the second light emitting region 2 is located between the first light emitting region 1 and the third light emitting region 3. The first light emitting region 1 may include a plurality of first pixel repeating units 11, the second light emitting region 2 may include a plurality of second pixel repeating units 21, and the third light emitting region 3 may include a plurality of third pixel repeating units 31. Further, the first pixel repeating unit 11, the second pixel repeating unit 21, and the third pixel repeating unit 31 may include n pixels, respectively, n ≧ 1 and n is an integer. For example, as shown in fig. 3, when the first pixel repeating unit 11, the second pixel repeating unit 21, and the third pixel repeating unit 31 are respectively configured to include three kinds of sub-pixels of red, green, and blue, one pixel repeating unit may be arranged. Of course, only the pixel repeating unit including three colors is taken as an example for description, and in other embodiments, four or more than four pixels with different colors may be included, which is not limited in the present application.
In the present embodiment, the pixel density of the first light emitting region 1 may be set to be greater than the pixel density of the third light emitting region 3. Therefore, in order to solve the dark line problem in the related art, the pitch between the adjacent second pixel repeating units 21 may be made smaller than the pitch between the adjacent third pixel repeating units 31. The pitch may be a distance between central axes of adjacent pixel repeating units. For example, as shown in fig. 3, taking the second pixel repeating unit 21A, the second pixel repeating unit 21B, the third pixel repeating unit 31A and the third pixel repeating unit 31B as an example, the distance between the second pixel repeating unit 21A and the second pixel repeating unit 21B is D1, the distance between the third pixel repeating unit 31A and the third pixel repeating unit 31B is D2, and D2 is greater than D1, so that the distance between each second pixel repeating unit can be reduced, and a complete pixel unit can be arranged between the first light emitting area 1 and the third light emitting area 3, so as to solve the problem of displaying dark lines.
According to the embodiment, the second light emitting area 2 is arranged between the first light emitting area 1 and the third light emitting area 3, the distance between the central axes of the adjacent second pixel repeating units 21 is smaller than the distance between the central axes of the adjacent third pixel repeating units 31, the area occupied by the second pixel repeating units 21 is reduced, the integral second pixel repeating units 21 can be arranged in the second light emitting area 2, dark lines are avoided, and the display effect is improved. The first light-emitting area 1 may be set as a non-transparent area, and the third light-emitting area 3 may be set as a transparent area, based on which, when the array substrate 100 is configured to an electronic device, the image pickup head or the photosensitive structure may be set corresponding to the third light-emitting area 3, so that light can be transmitted while display is ensured, which is beneficial to improving screen occupation ratio.
The reduction of the pitch between the adjacent second pixel repeating units may be, as shown in fig. 3, that the size of the sub-pixels in the second pixel repeating unit is smaller than the size of the sub-pixels in the third pixel repeating unit; alternatively, as shown in fig. 4, the pitch between adjacent sub-pixels in the second pixel repeating unit may be smaller than the pitch between adjacent sub-pixels in the third pixel repeating unit; in another embodiment, the size of the sub-pixels in the second pixel repeating unit may be smaller than the size of the sub-pixels in the third pixel repeating unit, and the distance between adjacent sub-pixels in the second pixel repeating unit may be smaller than the distance between adjacent sub-pixels in the third pixel repeating unit, which is not limited in this application. In the above embodiments, the pixel arrangement on the first light emitting region 1, the second light emitting region 2, and the third light emitting region 3 in the direction indicated by the arrow a on the array substrate 100 is exemplified. In fact, in the direction perpendicular to the arrow a, the arrangement of the pixels can also be referred to as shown in fig. 3 and 4, and will not be described again here.
In the above-described respective embodiments, the pitches between the sub-pixels in the adjacent second pixel repeating units 21 may be set to be equal. In other words, the second pixel repeating units 21 in the second light emitting region 2 are uniformly arranged. In another embodiment, further to dispose an integer number of second pixel repeating units 21 in the second light emitting region 2, as shown in fig. 5, the pitches between the sub-pixels in the adjacent second pixel repeating units 21 may be set to be unequal, which is beneficial to adjust the pitch between the central axes of the adjacent second pixel repeating units 21. When the distances between the central axes of the adjacent second pixel repeating units 21 are not equal, the minimum value of the central axes of the adjacent second pixel repeating units 21 may be smaller than the distance between the central axes of the adjacent third pixel repeating units 31.
For example, as shown in fig. 5, the sizes of the sub-pixels in the adjacent second pixel repeating units 21 may be set to be unequal and the pitches between the sub-pixels may be equal, so that the pitches between the central axes of the adjacent second pixel repeating units 21 are unequal. For example, as shown in fig. 5, taking the second pixel repeating unit 21A, the second pixel repeating unit 21B and the second pixel repeating unit 21C as an example, the size of the sub-pixels in the second pixel repeating unit 21A is smaller than the size of the sub-pixels in the second pixel repeating unit 21B, and the size of the sub-pixels in the second pixel repeating unit 21B is smaller than the size of the sub-pixels in the second pixel repeating unit 21C. Therefore, a spacing D11 between the central axes of the second pixel repeating unit 21A and the second pixel repeating unit 21B is smaller than a spacing D12 between the second pixel repeating unit 21B and the second pixel repeating unit 21C. Alternatively, in another embodiment, the sizes of the sub-pixels in the adjacent second pixel repeating units 21 may be set to be equal, and the pitches between the sub-pixels may be different, so that the pitches between the axes of the adjacent second pixel repeating units 21 may be different. And will not be described in detail herein.
In this embodiment, the size inequality of the second pixel repeating unit 21 may be irregularly changed or may be regularly changed. For example, since the pixel density of the first light emitting region 1 is less than the pixel density of the third light emitting regions 3 and 1, that is, the size of the first pixel repeating unit is less than the size of the third pixel repeating unit 31, as shown in fig. 5, the sizes of the second pixel repeating units sequentially increase in a direction from a side close to the first light emitting region 1 to a side close to the third light emitting region 3, that is, in a direction indicated by an arrow a in fig. 5, so that the transition between the first light emitting region 1 and the third light emitting region 3 is gradual, thereby avoiding a sudden change in display and improving the display effect. Further, the lengths of the plurality of second pixel repeating units increase in the direction indicated by the arrow a, and the sizes of the plurality of second pixel repeating units are equal in the direction perpendicular to the arrow a.
Based on the above embodiments, the light emitting structures in the plurality of first pixel repeating units 11, the plurality of second pixel repeating units 21, and the plurality of third pixel repeating units 31 may be manufactured in the same process by using the same mask, thereby reducing the number of process steps. Or, since the pixel densities of the first light emitting region 1 and the third light emitting region 3 are different, when the first pixel repeating unit 11 and the third pixel repeating unit 3 are prepared by using the same mask, the opening specifications of the mask region corresponding to the first pixel repeating unit 11 and the mask region corresponding to the third pixel repeating unit 3 are different, so that the amount of deformation is increased during screening, and a color mixing risk is generated. Therefore, in another embodiment, the plurality of first pixel repeating units 11 may be formed by an evaporation process and a plurality of third pixel repeating units may be formed by an inkjet printing process, so that on one hand, the risk of color mixing can be reduced, and on the other hand, the number of mask plates can be reduced, thereby reducing the production cost. In this embodiment, the plurality of second pixel repeating units 21 may be formed in the same manner as the plurality of first pixel repeating units 11, i.e., also by using an evaporation process; alternatively, the plurality of second pixel repeating units 21 may be formed in the same manner as the plurality of third pixel repeating units 31, i.e., by using an inkjet process, which is not limited in this application.
Based on the technical solution of the present application, as shown in fig. 6, the array substrate 100 may further include a substrate 102, a first electrode layer 103, and a second electrode layer 104. Here, the first electrode layer 103 is formed on the substrate 102, the light emitting structures of the first light emitting region 1, the second light emitting region 2, and the third light emitting region 3 are formed on the first electrode layer 103, and the second electrode layer 104 is formed on the light emitting layer 101. As shown in fig. 7, the first electrode layer 103 may include a plurality of rows of first electrode groups 4 disposed corresponding to the third light emitting areas 3, the first electrode groups 4 being arranged along a third direction X, the third direction X being perpendicular to a fourth direction Y, the fourth direction Y being an extending direction of the first electrode groups 4.
Referring to fig. 7, in an embodiment, each first electrode group 4 includes one first electrode 41, and each first electrode 41 extends along the fourth direction Y, and of course, the first electrode group 4 also extends along the fourth direction. Optionally, the third direction X is perpendicular to a fourth direction Y, the fourth direction Y is defined as a length direction of the first electrode 41, and the third direction is defined as a width direction of the first electrode. Each first electrode 41 corresponds to a plurality of light emitting structures 5, and optionally, the color of the light emitting structures on one first electrode is the same (for example, the light emitting structures 5A corresponding to the first electrode 41A are all red), and the color of the light emitting structures on the plurality of first electrodes 41 of one first electrode group 4 is also the same. For example, the first electrode 41A corresponds to the plurality of red light emitting structures 5A, the first electrode 41B corresponds to the plurality of green light emitting structures 5B, the first electrode 41C corresponds to the plurality of blue light emitting structures 5C, and the first electrode 41D corresponds to the plurality of red light emitting structures 5D.
In the third direction X, the first electrodes 41A of the first electrode group 4A and the first electrodes 41B of the first electrode group 4B are arranged in a staggered manner, i.e., two first electrodes of adjacent first electrode groups are arranged in a staggered manner. Optionally, the offset distance is 0.5 times the width of the first electrode. In the third direction X, the distances between the first electrode groups (for example, the first electrodes 41A and the first electrodes 41D) corresponding to the two adjacent light-emitting structures of the same color are reduced, and accordingly, the distances between the adjacent light-emitting structures of the same color are also reduced. For example, the distance between the red light emitting structure 5A corresponding to the first electrode 41A and the green light emitting structure 5B corresponding to the first electrode 41B is decreased, and the distance between the red light emitting structure 5A corresponding to the first electrode 41A and the red light emitting structure 5C corresponding to the first electrode 41D is decreased or eliminated when the third light emitting region 3 is a transparent region, so as to improve the display effect by reducing or eliminating the vertical stripes generated between the light emitting structures of the same color corresponding to the adjacent first electrode groups.
The distance between the central axis L1 of the first electrode group 4A (also the central axis of the first electrode 41 in this embodiment, the same applies hereinafter) and the central axis L2 of the adjacent first electrode group 4B is D, the distance between the central axis L1 of the first electrode group 4A and the central axis L3 of the first electrode group 4D corresponding to the adjacent red light-emitting structure is less than 3D, as can be seen by analogy, the distance between the central axes of the first electrode groups corresponding to the adjacent two light-emitting structures of the same color is less than n × D, and n is the number of colors of the light-emitting structures. Wherein the respective central axes L1, L2, L3 extend in the fourth direction Y. It is noted that the first electrode may be of an asymmetric configuration and the central axis may represent an approximate bisector of the first electrode group.
In two adjacent first electrode groups, taking the first electrode group 4A and the first electrode group 4B as an example, the first electrode group 4A and the first electrode group 4B (i.e., the first electrode 41A and the first electrode 41B) are spaced apart from each other, and the distances between the two are always the same, which is beneficial to simplifying the patterning process of the first electrode layer; in other embodiments, the two may be spaced apart unequally to reduce the effects of diffraction. In this embodiment, since the gap between the first electrode group 4A and the first electrode group 4B is not a straight line, it is advantageous to further reduce diffraction.
Alternatively, in this embodiment, each first electrode 41 includes an electrode block 411, and in this embodiment, the first electrode 41 may be understood as a monolithic electrode block. Each electrode block 411 corresponds to a plurality of light emitting structures 5, so that the electrode blocks 411 corresponding to the plurality of light emitting structures can be driven by the same driving circuit, thereby simplifying the structure of the driving circuit and reducing the cost.
In this embodiment, the projection of the electrode block 411 on the substrate is gourd-shaped, and the projection of the light emitting structure on the substrate 1 is circular. The gourd shape can be understood as: the shape of the electrode block 411 that is alternately increased and decreased in size in the extending direction (i.e., the extending direction of the first electrode 41, i.e., the fourth direction Y) is similar to the shape of a gourd, and of course, the gourd shape here corresponds to the shape of one or more gourds connected end to end and connected in series. The projection of the light emitting structure on the substrate 1 may be a circle (as shown in fig. 7), or may be a square (as shown in fig. 8), and in other embodiments, the projection may also be an ellipse or a dumbbell, which is not described in detail.
In another embodiment, referring to fig. 9, each first electrode group includes a first electrode 42, the first electrode 42 includes a plurality of electrode blocks 421 and a connection portion 422 connecting adjacent electrode blocks, and the connection portion 422 may be formed on the same layer as the first electrode 42 or may be a connection line routed through other film layers. Each first electrode block 421 corresponds to one light-emitting structure 5, and the projections of the electrode blocks 421 on the substrate 1 are all circular. Of course, in other embodiments, the projection of the electrode block 421 on the substrate 1 may also be in the shape of a circle, a square, an ellipse, etc. The structure other than the connection portion is substantially the same as that of the embodiment shown in fig. 5, and will not be described in detail.
Referring to fig. 10, in an embodiment, projections of the first electrode layer 103 and the light emitting layer 101 on the substrate are as shown in fig. 10, the first electrode layer includes a plurality of first electrode groups 6 arranged along a third direction X1, and the first electrode groups 6 extend along a fourth direction Y1. It should be noted that the third direction X1 and the fourth direction Y1 are different from the third direction X and the fourth direction Y in the above embodiments.
In the present embodiment, each first electrode group 6 includes two first electrodes 61, and in other embodiments, the first electrode group 6 may include a plurality of first electrodes 61. The first electrodes 61 extend in the fourth direction Y1, and the first electrode group 6 also extends in the fourth direction Y1. Each of the first electrodes 61 includes a plurality of electrode blocks 611 and a connection portion 612 connecting adjacent electrode blocks 611, and the connection portion 612 connects electrode blocks of different first electrodes (for example, the first electrode 61A and the first electrode 61B). Each first electrode 61 corresponds to a plurality of light emitting structures, each electrode block 611 corresponds to one light emitting structure, the light emitting structures corresponding to the same first electrode 61 are of the same color, and the light emitting structures corresponding to the same first electrode group 6 are of the same color.
Referring to fig. 10, in the third direction X1, the first electrodes of two adjacent first electrode groups are staggered, for example, the first electrodes 61B of the first electrode group 6A and the first electrodes 61C of the second electrode group 6B are staggered, and in the third direction X1, the distance between the first electrode groups (for example, the first electrodes 61B and the first electrodes 61E) corresponding to two adjacent light emitting structures of the same color is reduced, and correspondingly, the distance between the adjacent light emitting structures of the same color is also reduced, so that when the third light emitting region 3 is a transparent display region, the vertical stripes between the light emitting structures of the same color corresponding to the adjacent first electrode groups are reduced or eliminated. Alternatively, in the third direction X1, adjacent first electrodes are staggered from each other, for example, the first electrode 61B and the first electrode 61C, and the staggered distance is 1.5 times the width of the first electrode 61B (or 61C). The first electrode 61B and the first electrode 61A are aligned in the third direction in the prior art, and the first electrode 61B and the first electrode 61A are located at the positions shown in fig. 10 in this embodiment, so the offset distance is 1.5 times the width of the first electrode.
Due to the staggered arrangement of the first electrodes (e.g., the first electrode 61B and the first electrode 61C) of the two first electrode groups, the distance between the first electrode 21B of the corresponding first electrode group 6A and the first electrode 61E of the first electrode group 6C is correspondingly reduced, the distance between the red pixel 51 corresponding to the first electrode 61B and the red pixel 52 corresponding to the first electrode 61E is also correspondingly reduced, and the streaks of the red pixel 51 and the red pixel 52 are reduced or eliminated when the third light-emitting region 3 is a transparent region. In this embodiment, the central axis of the first electrode group is located between the two first electrodes. The distance between the central axis L4 of the first electrode group 6A and the central axis L5 of the first electrode group 6B is d1, the distance between the central axis L4 of the first electrode group 6A and the central axis L6 of the first electrode group 6C is less than 3 × d1, corresponding to the analogy, the distance between the central axes of the first electrode groups corresponding to two adjacent light emitting structures of the same color is less than n × d1, and n is the number of colors of the light emitting structures.
