Fig. 2 is a schematic structural diagram of an array substrate according to an embodiment of the present invention. Fig. 3 is a schematic structural diagram of another array substrate according to an embodiment of the present invention. As shown in fig. 2 and 3, the array substrate includes a plurality of pixel unit rows 100 extending along a first direction X, each pixel unit row 100 includes a plurality of first pixel units 110, a plurality of second pixel units 120, and a plurality of third pixel units 130, each first pixel unit 110 includes two first sub-pixels 111 arranged along a second direction Y, each second pixel unit 120 includes two second sub-pixels 112 arranged along the second direction Y, each third pixel unit 130 includes one third sub-pixel 113 extending along the second direction Y, or two third sub-pixels 113 arranged along the second direction Y, the first sub-pixels 111, the second sub-pixels 112, and the third sub-pixels 113 have different emission colors, and a minimum included angle between the second direction Y and the first direction X is a, and 0 ° < a ≦ 90 °. The plurality of pixel units in the pixel unit row 100 are circularly arranged according to the sequence of the first pixel unit 110, the second pixel unit 120, the third sub-pixel unit 130 and the second pixel unit 120, and the odd pixel unit row and the even pixel unit row are arranged in a staggered manner.

It should be noted that, in this embodiment, the types of the pixel units located at the head and the tail of the row in each pixel unit row 100 are not specifically limited, and may be the first pixel unit 110, the second pixel unit 120, or the third pixel unit 130.
Compared with the structure of the array substrate in the prior art shown in fig. 1, the number of the first sub-pixels 111 in the first pixel unit 110 in fig. 2 is increased, but the occupied area of the first pixel unit 110 is not changed, so that the total number of the sub-pixels in a unit area is increased, the physical resolution is increased, the display picture is finer, and when the sub-pixels are the pixels recognizable by the human eye, the structure of the array substrate provided in fig. 2 can increase the number of the pixels recognizable by the human eye, and the viewing experience of a user is improved.
On the other hand, compared with the structure of the array substrate in the prior art shown in fig. 1, the array substrate provided in fig. 3 has an increased number of sub-pixels in the first pixel unit 110 and the third pixel unit 130, which can achieve the above-mentioned benefits of the array substrate shown in fig. 2, and the number of the third sub-pixels 131 in the third pixel unit 130 is also increased, so that the effect is better. In addition, as shown in fig. 3, two sub-pixels with the same color in the same pixel unit are arranged in a staggered manner, so that the sub-pixels with the same color are not distributed in a concentrated manner, and the sub-pixels with different colors can be distributed in a penetrating manner, which is beneficial to better color mixing of light emitted by the sub-pixels with three different colors.
In the technical scheme provided by this embodiment, by arranging the pixel unit row 100 extending along the first direction X, the first pixel unit 110 includes two first sub-pixels 111 arranged along the second direction Y, the second pixel unit 120 includes two second sub-pixels 121 arranged along the second direction Y, and the third pixel unit 130 includes one third sub-pixel 131 or two third sub-pixels 131 arranged along the second direction Y, wherein a minimum included angle a between the second direction Y and the first direction X is in a range of 0 ° < a ≦ 90 °, so that the number of the first sub-pixels 111 in at least the first pixel unit 110 is increased, the size is small, the physical resolution of the display panel is increased, the granular sensation problem of the display screen is improved, the distribution uniformity of each sub-pixel is improved, and the display effect of the display panel is further improved.
Fig. 4 is a schematic sectional view along a broken line BC in fig. 2. Fig. 5 is a schematic sectional view along a broken line DE in fig. 3. As shown in fig. 5, the first sub-pixel 111, the second sub-pixel 121, and the third sub-pixel 131 each include a first electrode 201, an organic light emitting function layer 202, and a second electrode 203, which are sequentially stacked along the light emitting direction Z of the array substrate, as shown in fig. 4 and 5, two first sub-pixels 111 in the same first pixel unit 110 share the same organic light emitting function layer 202, and two second sub-pixels 121 in the same second pixel unit 120 share the same organic light emitting function layer 202.
It should be noted that, on one hand, the distance between two first sub-pixels 111 in the first pixel unit 110 and the distance between two second sub-pixels 121 in the second pixel unit 120 are no longer limited by the process limit size of the bridge between the adjacent openings of the corresponding mask, and the distance between two first sub-pixels 111 in the same first pixel unit 110 and the distance between two second sub-pixels 121 in the same second pixel unit 120 can be set smaller than the process limit size of the corresponding bridge, thereby achieving the beneficial effect of increasing the pixel density and the pixel aperture ratio of the display panel. On the other hand, an opening of a mask plate for preparing the light-emitting functional layer 202 of the first sub-pixel 111 is arranged corresponding to one first pixel unit 110, and is not arranged corresponding to one first sub-pixel 111 any more; the opening of the mask for preparing the light-emitting functional layer 202 of the second sub-pixel 121 corresponds to one second pixel unit 120, and is no longer arranged corresponding to one second sub-pixel 121, and the distance between the adjacent same-color pixel units is obviously greater than the distance between the adjacent same-color sub-pixels, so that the distance between the adjacent openings of the corresponding mask is increased by the arrangement mode, and the preparation difficulty of the mask is reduced.
On this basis, as shown in fig. 5, when the third pixel unit 130 includes two third sub-pixels 131, the two third sub-pixels 131 in the same third pixel unit 130 may share the same organic light emitting function layer 202.
The above arrangement further enables the distance between the two third sub-pixels 131 in the third pixel unit 130 to be no longer limited by the process limit size of the bridge between the adjacent openings of the corresponding masks, and the distance between the two third sub-pixels 131 in the same third pixel unit 130 can be set smaller than the process limit size of the bridge, thereby increasing the pixel density and the pixel aperture ratio of the display panel. And the opening of the mask for preparing the light-emitting functional layer 202 of the third sub-pixel 131 is arranged corresponding to one third pixel unit 130, and is not arranged corresponding to one third sub-pixel 131, so that the distance between the adjacent openings corresponding to the mask is increased, and the preparation difficulty of the mask is reduced.
Specifically, fig. 6 is a schematic structural diagram of an organic light emitting functional layer of the pixel array in the array substrate in fig. 2. Fig. 7 is a schematic structural diagram of an organic light emitting functional layer of a pixel array in the array substrate in fig. 3.
Illustratively, as shown in fig. 2, a is 90 °, and the third pixel unit 130 includes a third sub-pixel 111, so as to reduce the change to the related manufacturing process of the array substrate in the prior art and increase the compatibility with the prior art while achieving the effect of improving the display effect of the display panel, and thus, the related process in the prior art can be partially used to achieve the beneficial effects of reducing the difficulty of the array substrate manufacturing technology and the manufacturing cost.
Fig. 8 is a schematic cross-sectional view taken along a dashed line BC in fig. 2. As shown in fig. 8, the array substrate further includes a plurality of pixel circuits, the pixel circuits are used for driving the corresponding sub-pixels to emit light, and two first sub-pixels 111 in the same first pixel unit 110 share the same pixel circuit. It should be noted that fig. 8 only illustrates the driving transistor 300 in the pixel circuit to simplify the structure of the drawing, and it is understood that the pixel circuit includes other circuit elements besides the driving transistor.
The arrangement mode can enable the first pixel unit 110 to correspond to only one pixel circuit, so that the occupied space of the pixel circuit corresponding to the first pixel unit 110 is reduced, the layout difficulty of the pixel circuit is further reduced, the distance between the adjacent pixel circuits is increased, and the probability of mutual interference between the adjacent pixel circuits is reduced.
Optionally, as shown in fig. 3, a is greater than 0 ° < 90 °, and the third pixel unit 130 includes two third sub-pixels 131, so as to increase the physical pixel density of the array substrate more effectively, and make the image display finer and finer.
Fig. 9 is a schematic view of another cross-sectional structure along the dashed line DE in fig. 3. As shown in fig. 9, the array substrate further includes a plurality of pixel circuits, the pixel circuits are used for driving the corresponding sub-pixels to emit light, two first sub-pixels 111 in the same first pixel unit 110 share the same pixel circuit, and two third sub-pixels 131 in the same third pixel unit 130 share the same pixel circuit. To simplify the structure of the drawing, fig. 9 only illustrates the driving transistor 300 in the pixel circuit, and it is understood that the pixel circuit includes other circuit elements in addition to the driving transistor.
The arrangement mode can enable the first pixel unit 110 and the third pixel unit 130 to correspond to only one pixel circuit, so that the occupied space of the pixel circuits corresponding to the first pixel unit 110 and the third pixel unit 130 is reduced, the display effect of the display panel is effectively improved, meanwhile, the layout difficulty of the pixel circuits is reduced, the distance between the adjacent pixel circuits is increased, and the probability of mutual interference between the adjacent pixel circuits is reduced.
Fig. 10 is a schematic view of another cross-sectional structure taken along the dashed line DE in fig. 3. As shown in fig. 10, two first sub-pixels 111 in the same first pixel unit 110 share the same pixel circuit, two third sub-pixels 131 in the same third pixel unit 130 share the same pixel circuit, and two second sub-pixels 121 in the same second pixel unit 120 share the same pixel circuit, so as to further reduce the difficulty of layout of the pixel circuits, increase the pitch between adjacent pixel circuits, and reduce the probability of mutual interference between adjacent pixel circuits.
Illustratively, with continued reference to fig. 3, a is 45 °.
It should be noted that when a is too large, the distance between two sub-pixels in the same pixel unit in the first direction X is small, and the two sub-pixels are distributed more intensively, which is not favorable for color mixing of light emitted by the sub-pixels with three different colors; when a is too small, the distance between two sub-pixels in the same pixel unit in the first direction X is large, and the distance between two sub-pixel columns where the two sub-pixels are located is large, so that on one hand, the pixel density is reduced, and on the other hand, the distance between adjacent sub-pixels is large, which is not favorable for color mixing of light emitted by sub-pixels with different colors. Experiments prove that when A is 45 degrees, the distance between two sub-pixels in the same pixel unit in the first direction X is proper, the distance between the sub-pixel columns where the two sub-pixels are located is proper, and light emitted by the adjacent sub-pixels with different colors can be well mixed.
Fig. 11 is a schematic structural diagram of another array substrate according to an embodiment of the present invention. On the basis of the structure of the array substrate shown in fig. 3, the pixel unit row 100 further includes a first sub-pixel 101 and a second sub-pixel 102, the first sub-pixel 101 and the second sub-pixel 102 are respectively disposed at the head and the tail of the row of the pixel unit row 100, the pixel unit disposed adjacent to the first sub-pixel 101 in the same row is a first pixel unit 140, the sub-pixels far from the second sub-pixel 102 in the first sub-pixel 101 and the first pixel unit 140 are arranged along a third direction W, the pixel unit disposed adjacent to the second sub-pixel 102 in the same row is a second pixel unit 150, and the sub-pixels far from the first sub-pixel 101 in the second sub-pixel 102 and the second pixel unit 150 are arranged along the third direction W, wherein the third direction W is perpendicular to the first direction X.
The conventional display panel is rectangular, the arrangement of the first sub-pixel 101 and the second sub-pixel 102 enables the overall shape of a pixel array in the array substrate to be closer to a rectangle, the irregularity of the edges of the left side and the right side in a display picture is reduced, and the display effect of the display panel is improved.
Further, referring to fig. 11, along the third direction W, the length of the third pixel unit 130 is a, the length of the first pixel unit 110 is b, and the length of the second pixel unit 120 is c, where a is b is c.
It should be noted that, when the lengths of the first pixel unit 110, the second pixel unit 120, and the third pixel unit 130 in the third direction W are equal, the edge of each pixel unit row 100 close to any adjacent pixel unit row 100 is located on a straight line extending along the first direction X, which is beneficial to improving the linearity of the display screen and effectively improving the sawtooth problem of the display screen.
Fig. 12 is a schematic structural diagram of another array substrate according to an embodiment of the present invention. The structure of the array substrate shown in fig. 12 is similar to that of the array substrate shown in fig. 11, except that in fig. 12, the first sub-pixel 111, the second sub-pixel 121, and the third sub-pixel 131 are all equal in shape and area, and thus the plurality of first sub-pixels 111 and the plurality of third sub-pixels 131 can be formed by using the same mask plate in any case where two sub-pixels share the same light-emitting function layer in each pixel unit; and in the second case, the sub-pixels correspond to the light-emitting functional layers one to one.
In addition, in the present embodiment, the light emission colors of the first sub-pixel, the second sub-pixel, and the third sub-pixel are any one of red, green, and blue, and are different from each other.
Since red, green, and blue are three primary colors of light, and red, green, and blue with different intensities can be mixed to obtain light of various colors, the emission colors of the first sub-pixel, the second sub-pixel, and the third sub-pixel are set to be any one of red, green, and blue, respectively, and are different from each other, so that the display colors of the display panel can be varied, and the display colors of the display panel can be enriched.
Further, the emission color of the third sub-pixel is blue.
Specifically, referring to fig. 2, in the technical solution provided in this embodiment, the size of the third sub-pixel 131 may be larger than that of the first sub-pixel 111 and the second sub-pixel 121, and in consideration of the influence of the characteristics of the forming material, the lifetime of the blue sub-pixel is shorter than the lifetimes of the red sub-pixel and the green sub-pixel, so as to avoid the lifetime of the blue sub-pixel from being reduced, the light emitting color of the third sub-pixel 131, which may be relatively larger in size, is set to be blue, thereby reducing the current density of the blue sub-pixel and improving the lifetime thereof.
