The following describes the pixel structure and the display device provided by the present invention in further detail with reference to the accompanying drawings.
Example one
Fig. 1 is a schematic structural diagram of a pixel structure according to an embodiment of the present invention. For simplicity, only a part of the pixel structure is shown in the drawings, the number of pixels in an actual product is not limited thereto, and the number of pixel units can be changed correspondingly according to actual display requirements.
As shown in fig. 1, the present invention provides a pixel structure, including a plurality of repeating units 10 arranged in a matrix, the repeating units 10 being repeatedly arranged along a first direction and a second direction, each repeating unit 10 including a first sub-pixel 101, two second sub-pixels 102, and two third sub-pixels 103 arranged along the first direction, the first sub-pixel 101 being located in the middle, the second sub-pixel 102 and the third sub-pixels 103 being located on both sides of the first sub-pixel 101, respectively, and one of the three sub-pixels having a luminance greater than the remaining two sub-pixels being divided into two sub-pixels in the second direction.
Preferably, the first direction is perpendicular to the second direction. In this embodiment, as shown in fig. 1, the first direction is a row direction (X direction), and the second direction is a column direction (Y direction).
In the present embodiment, the repeating unit 10 includes a second sub-pixel 102, a third sub-pixel 103, a first sub-pixel 101, a second sub-pixel 102, and a third sub-pixel 103, which are sequentially arranged along the first direction (X direction), the first sub-pixel 101 is respectively shared by the second sub-pixel 102 and the third sub-pixel 103 on two sides to form two pixel unit groups, as shown in fig. 2, the first sub-pixel 101 forms a first pixel unit group P10 with the second sub-pixel 102 and the third sub-pixel 103 on one side (for example, on the left side in fig. 2), and the first sub-pixel 101 forms a second pixel unit group P20 with the second sub-pixel 102 and the third sub-pixel 103 on the other side (for example, on the right side in fig. 2).
The second sub-pixel 102 is divided into two sub-pixels in the second direction (Y direction), and in the first pixel unit P10, the first sub-pixel 101 and the third sub-pixel 103 are shared by the two sub-pixels divided from the second sub-pixel 102 to form two pixel units, specifically, the first sub-pixel 101 and the third sub-pixel 103 and one sub-pixel (for example, the upper side in fig. 2) divided from the second sub-pixel 102 form a first pixel unit P11, and the first sub-pixel 101 and the third sub-pixel 103 and another sub-pixel (for example, the lower side in fig. 2) divided from the second sub-pixel 102 form a second pixel unit P12. Accordingly, in the second pixel unit P20, the first sub-pixel 101, the third sub-pixel 103 and one of the sub-pixels (e.g., the upper side in fig. 2) separated from the second sub-pixel 102 constitute a third pixel unit P21, and the first sub-pixel 101, the third sub-pixel 103 and another of the sub-pixels (e.g., the lower side in fig. 2) separated from the second sub-pixel 102 constitute a fourth pixel unit P22.
In the present embodiment, four pixel units are formed in each repeating unit 10, and the first sub-pixel 101 is shared four times and the third sub-pixel 103 is shared twice. The sharing of the sub-pixels enables more pixel units to be formed in the same area, and is beneficial to improving the resolution of the display device. Optionally, the first sub-pixel 101 may be divided into two or four sub-pixels, each of the two divided sub-pixels shares twice, or each of the four divided sub-pixels and the remaining sub-pixels form a pixel unit, or the third sub-pixel 103 may be divided into two sub-pixels, each of the sub-pixels and the remaining sub-pixels form a pixel unit, or the first sub-pixel 101 and the third sub-pixel 103 may also be divided at the same time, so that the same opening of the evaporation mask may be used to evaporate two or four divided sub-pixels, which may reduce the difficulty of the manufacturing process and the evaporation process of the evaporation mask.
In this embodiment, the first sub-pixel 101 is a red sub-pixel, the second sub-pixel 102 is a green sub-pixel, and the third sub-pixel 103 is a blue sub-pixel, and each pixel unit includes a red sub-pixel, a green sub-pixel, and a blue sub-pixel, so that full color display in a real sense can be realized. Moreover, because the red sub-pixel has the longest service life, the red sub-pixel is shared four times, the red sub-pixel can be used to the maximum extent, the green sub-pixel is brightest, the green sub-pixel is divided into two sub-pixels, the brightness of the display device cannot be influenced, in addition, when the PPI is calculated, the PPI is calculated by the brightest sub-pixel (the green sub-pixel), the PPI is increased, the resolution ratio of the display device is further improved, meanwhile, the two divided sub-pixels can be simultaneously evaporated by adopting the same opening of the evaporation mask plate, and the difficulty of the manufacturing process and the evaporation process of the evaporation mask plate can be reduced.
In other embodiments, the first sub-pixel 101 may be a blue sub-pixel, the second sub-pixel 102 may be a green sub-pixel, and the third sub-pixel 103 may be a red sub-pixel. Thus, the blue sub-pixel is shared four times and the red sub-pixel is shared twice. The blue sub-pixel and the red sub-pixel may be separated according to the number of times of sharing.
In this embodiment, preferably, the first sub-pixel 101 and the third sub-pixel 103 have the same shape and area, and can be formed by vapor deposition using the same vapor deposition mask, so as to save the manufacturing cost of the mask. Of course, the shape and area of the first sub-pixel 101 and the third sub-pixel 103 may also be different, for example, the shape is the same, the area is different, or the shape is different, the area is the same, or the shape and the area are different.
More preferably, the first sub-pixel 101 and the third sub-pixel 103 are rectangular or square, and the second sub-pixel 102 is divided into two sub-pixels: the first green sub-pixel 1021 and the second green sub-pixel 1022 are rectangular, and the long side direction of the first green sub-pixel 1021 and the second green sub-pixel 1022 is parallel to the first direction, and the short side direction is parallel to the second direction. For example, the first subpixel 101 and the third subpixel 103 are square, and the length of the long side of the first green slave subpixel 1021 and the length of the second green slave subpixel 1022 are 2 times the length of the short side. However, it should be understood that the shapes of the first sub-pixel 101, the second sub-pixel 102 and the third sub-pixel 103 are not limited to a rectangle, and may be quadrangles other than a rectangle, or one or any combination of polygons such as a triangle, a pentagon, a hexagon, an octagon, etc., and the shape and/or area of each sub-pixel may be adjusted according to the color matching requirement.
Each sub-pixel includes a light emitting region (display region) and a non-light emitting region (non-display region), and the light emitting region of each sub-pixel includes a cathode, an anode, and an electroluminescent layer (organic light emitting layer) between the cathode and the anode for generating light of a predetermined color to realize display. It is generally necessary to form electroluminescent layers of corresponding colors (e.g., red, green, or blue) in the light-emitting regions of the pixel regions of corresponding colors by using a three-layer evaporation process. When the shapes and areas of the first sub-pixel 101 and the third sub-pixel 103 are the same, the same mask plate can be used to form red and blue electroluminescent layers, so that only two mask plates need to be manufactured, and the manufacturing cost of the mask plates is saved.
Preferably, the repeating units 10 adjacent to each other in the second direction are arranged in a staggered manner in the first direction, specifically, the repeating units 10 in the odd-numbered rows are aligned with each other, that is, the repeating units 10 in the odd-numbered rows are arranged in the same manner, the repeating units 10 in the even-numbered rows are aligned with each other, that is, the repeating units 10 in the even-numbered rows are arranged in the same manner, and the repeating units 10 in the even-numbered rows are arranged in a staggered manner in the row direction with the repeating units 10 in the odd-numbered rows.
Preferably, the repeating unit 10 of the even row is shifted from the repeating unit 10 of the odd row by a distance of at least one sub-pixel in the row direction, in this embodiment, by a distance of at least one green sub-pixel. As shown in fig. 1, a distance H between a leftmost green sub-pixel of the odd-numbered column and a leftmost green sub-pixel of the even-numbered column includes a length of the green sub-pixel in the first direction and also includes a partial gap between the green sub-pixel and the blue sub-pixel in the odd-numbered row. The repeating units 10 in the even-numbered rows and the repeating units 10 in the odd-numbered rows are arranged in a staggered manner in the row direction, so that the pixel arrangement is more uniform, and the display effect of the display device is improved.
It should be noted that two adjacent repeating units in the second direction may also be controlled by timing, so that the pixel unit in one repeating unit realizes left-eye display, and the pixel unit in the other repeating unit realizes right-eye display, thereby enabling the pixel structure to be applied to VR and 3D display technologies. Alternatively, in one repeating unit, the first pixel cell group P10 may be controlled to realize left-eye display, and the second pixel cell group P20 may realize right-eye display, or in the first pixel cell group P10, the first pixel cell P11 may be controlled to realize left-eye display, and the second pixel cell P12 may be controlled to realize right-eye display, so that the pixel structure may be applied to VR and 3D display technologies.
It is understood that, in another embodiment of the present invention, the first direction may be a column direction (e.g., a Y direction in fig. 1), and the second direction may be a row direction (e.g., an X direction in fig. 1), so that the schematic structure diagram of the pixel structure described in fig. 1 needs to be adjusted to obtain the pixel structure described in this embodiment, which is similar to the pixel structure described above and is not repeated herein.
Example two

As shown in fig. 3, the present invention provides a pixel structure, including a plurality of repeating units 10 arranged in a matrix, the repeating units 10 being repeatedly arranged along a first direction and a second direction, each repeating unit 10 including a first sub-pixel 101, two second sub-pixels 102, and two third sub-pixels 103 arranged along the first direction, the first sub-pixel 101 being located in the middle, the second sub-pixel 102 and the third sub-pixels 103 being located on both sides of the first sub-pixel 101, respectively, and one of the three sub-pixels having a luminance greater than the remaining two sub-pixels being divided into two sub-pixels in the second direction.
The difference between the present embodiment and the first embodiment is that, in the present embodiment, the repeating unit 10 includes a third sub-pixel 103, a second sub-pixel 102, a first sub-pixel 101, a third sub-pixel 103, and a second sub-pixel 102, which are sequentially arranged along the first direction.
In the present embodiment, the repeating unit 10 includes a third sub-pixel 103, a second sub-pixel 102, a first sub-pixel 101, a third sub-pixel 103, and a second sub-pixel 102 sequentially arranged along the first direction (X direction), the first sub-pixel 101 is respectively shared by the second sub-pixel 102 and the third sub-pixel 103 on two sides to form two pixel unit groups, as shown in fig. 4, the first sub-pixel 101 forms a first pixel unit group P10 with the second sub-pixel 102 and the third sub-pixel 103 on one side (for example, on the left side in fig. 4), and the first sub-pixel 101 forms a second pixel unit group P20 with the second sub-pixel 102 and the third sub-pixel 103 on the other side (for example, on the right side in fig. 4).
The second sub-pixel 102 is divided into two sub-pixels in the second direction (Y direction), in the first pixel unit P10, the first sub-pixel 101 and the third sub-pixel 103 are shared by the two sub-pixels divided from the second sub-pixel 102 to form two pixel units, specifically, the first sub-pixel 101 and the third sub-pixel 103 and one sub-pixel (for example, the upper side in fig. 4) divided from the second sub-pixel 102 form a first pixel unit P11, and the first sub-pixel 101 and the third sub-pixel 103 and another sub-pixel (for example, the lower side in fig. 4) divided from the second sub-pixel 102 form a second pixel unit P12. Accordingly, in the second pixel unit P20, the first sub-pixel 101, the third sub-pixel 103 and one of the sub-pixels (e.g., the upper side in fig. 4) separated from the second sub-pixel 102 constitute a third pixel unit P21, and the first sub-pixel 101, the third sub-pixel 103 and another of the sub-pixels (e.g., the lower side in fig. 4) separated from the second sub-pixel 102 constitute a fourth pixel unit P22.
In the present embodiment, the repeating unit 10 of the even-numbered row is shifted from the repeating unit 10 of the odd-numbered row by a distance of at least one blue subpixel in the row direction. As shown in fig. 3, a distance H between a leftmost blue sub-pixel of the odd-numbered column and a leftmost blue sub-pixel of the even-numbered column includes a length of the blue sub-pixel in the first direction and also includes a partial gap between the blue sub-pixel and the green sub-pixel in the odd-numbered row. The repeating units 10 in the even-numbered rows and the repeating units 10 in the odd-numbered rows are arranged in a staggered manner in the row direction, so that the pixel arrangement is more uniform, and the display effect of the display device is improved.
It is understood that, in another embodiment of the present invention, the first direction may be a column direction (e.g., a Y direction in fig. 3), and the second direction may be a row direction (e.g., an X direction in fig. 3), so that the schematic structure diagram of the pixel structure illustrated in fig. 3 needs to be adjusted to obtain the pixel structure illustrated in this embodiment, which is similar to the pixel structure described above, and thus, the description of this embodiment is omitted here.

The difference between this embodiment and the first embodiment is that, in this embodiment, the first sub-pixel 101 is a green sub-pixel, the second sub-pixel 102 is a red sub-pixel, and the third sub-pixel 103 is a blue sub-pixel.
In this embodiment, the repeating unit 10 includes a second sub-pixel 102, a third sub-pixel 103, a first sub-pixel 101, a second sub-pixel 102, and a third sub-pixel 103 sequentially arranged along a first direction (X direction), the first sub-pixel 101 is divided into two sub-pixels in the second direction (Y direction), and the two sub-pixels divided by the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 constitute two pixel units. Specifically, the second sub-pixel 102, the third sub-pixel 103 and one of the sub-pixels (e.g., the upper side in fig. 6) separated from the first sub-pixel 101 constitute a first pixel unit P11, and the second sub-pixel 102, the third sub-pixel 103 and another of the sub-pixels (e.g., the lower side in fig. 6) separated from the first sub-pixel 101 constitute a second pixel unit P12.
In this embodiment, the first sub-pixel 101 is a green sub-pixel, the second sub-pixel 102 is a red sub-pixel, the third sub-pixel 103 is a blue sub-pixel, and each pixel unit includes a red sub-pixel, a green sub-pixel, and a blue sub-pixel, so that full color display in a real sense can be realized. Moreover, the green sub-pixel is brightest, the green sub-pixel is divided into two sub-pixels, the brightness of the display device is not affected, the PPI is calculated by the brightest sub-pixel (green sub-pixel), the number of the green sub-pixels is increased, the PPI is increased, the resolution of the display device is further improved, meanwhile, the two divided sub-pixels can be simultaneously evaporated by adopting the same opening of the evaporation mask plate, and the difficulty of the manufacturing process and the evaporation process of the evaporation mask plate can be reduced.
In other embodiments, the first sub-pixel 101 is a green sub-pixel, the second sub-pixel 102 may be a blue sub-pixel, and the third sub-pixel 103 may be a red sub-pixel.
In this embodiment, preferably, the second sub-pixel 102 and the third sub-pixel 103 have the same shape and area, and can be formed by vapor deposition using the same vapor deposition mask, so as to save the manufacturing cost of the mask. Of course, the shapes and areas of the second sub-pixel 102 and the third sub-pixel 103 may be different, for example, the shapes and areas are the same, or the shapes and areas are different, or the areas and the areas are different.
More preferably, the second sub-pixel 102 and the third sub-pixel 103 are rectangular or square in shape, and the first sub-pixel 101 is divided into two sub-pixels: the first green sub-pixel 1021 and the second green sub-pixel 1022 are rectangular, and the long side direction of the first green sub-pixel 1021 and the second green sub-pixel 1022 is parallel to the first direction, and the short side direction is parallel to the second direction. For example, the first subpixel 101 and the third subpixel 103 are square, and the length of the long side of the first green slave subpixel 1021 and the length of the second green slave subpixel 1022 are 2 times the length of the short side. However, it should be understood that the shapes of the first sub-pixel 101, the second sub-pixel 102 and the third sub-pixel 103 are not limited to a rectangle, and may be quadrangles other than a rectangle, or one or any combination of polygons such as a triangle, a pentagon, a hexagon, an octagon, etc., and the shape and/or area of each sub-pixel may be adjusted according to the color matching requirement.
Each sub-pixel includes a light emitting region (display region) and a non-light emitting region (non-display region), and the light emitting region of each sub-pixel includes a cathode, an anode, and an electroluminescent layer (organic light emitting layer) between the cathode and the anode for generating light of a predetermined color to realize display. It is generally necessary to form electroluminescent layers of corresponding colors (e.g., red, green, or blue) in the light-emitting regions of the pixel regions of corresponding colors by using a three-layer evaporation process. When the shapes and areas of the second sub-pixel 102 and the third sub-pixel 103 are the same, the same mask plate can be used to form red and blue electroluminescent layers, so that only two mask plates need to be manufactured, and the manufacturing cost of the mask plates is saved.
The repeating units 10 adjacent to each other in the second direction are arranged in a staggered manner in the first direction, specifically, the repeating units 10 in the odd-numbered rows are aligned with each other, that is, the repeating units 10 in the odd-numbered rows are arranged in the same manner, the repeating units 10 in the even-numbered rows are aligned with each other, that is, the repeating units 10 in the even-numbered rows are arranged in the same manner, and the repeating units 10 in the even-numbered rows and the repeating units 10 in the odd-numbered rows are arranged in a staggered manner in the row direction. Therefore, the pixel arrangement is more uniform, and the display effect of the display device is improved.
Preferably, the repeating unit 10 of the even-numbered row is shifted from the repeating unit 10 of the odd-numbered row by a distance of at least one sub-pixel in the row direction, in this embodiment, by a distance of at least one red sub-pixel. As shown in fig. 5, the distance H between the leftmost red sub-pixel in the odd-numbered column and the leftmost red sub-pixel in the even-numbered column includes the length of the red sub-pixel in the first direction and also includes a partial gap between the red sub-pixel and the green sub-pixel in the odd-numbered row.
It should be noted that two adjacent repeating units in the second direction may also be controlled by timing, so that the pixel unit in one repeating unit realizes left-eye display, and the pixel unit in the other repeating unit realizes right-eye display, thereby enabling the pixel structure to be applied to VR and 3D display technologies. Alternatively, in one repeating unit, the first pixel unit P11 may be controlled to realize left-eye display, and the second pixel unit P12 may realize right-eye display.
It is understood that, in another embodiment of the present invention, the first direction may be a column direction (e.g., a Y direction in fig. 5), and the second direction may be a row direction (e.g., an X direction in fig. 5), so that the schematic structure diagram of the pixel structure described in fig. 1 needs to be adjusted to obtain the pixel structure described in this embodiment, which is similar to the pixel structure described above and is not repeated herein.

The present embodiment is different from the third embodiment in that, in the present embodiment, the repeating unit 10 includes a third sub-pixel 103, a first sub-pixel 101, a second sub-pixel 102, a third sub-pixel 103, and a first sub-pixel 101, which are sequentially arranged along the first direction.

Specifically, the second sub-pixel 102, the third sub-pixel 103 and one of the sub-pixels (e.g., the upper side in fig. 8) separated from the first sub-pixel 101 constitute a first pixel unit P11, and the second sub-pixel 102, the third sub-pixel 103 and another of the sub-pixels (e.g., the lower side in fig. 8) separated from the first sub-pixel 101 constitute a second pixel unit P12.
In the present embodiment, the repeating unit 10 of the even-numbered row is shifted from the repeating unit 10 of the odd-numbered row by a distance of at least one blue subpixel in the row direction. As shown in fig. 7, a distance H between the leftmost blue sub-pixel of the odd-numbered column and the leftmost blue sub-pixel of the even-numbered column includes a length of the blue sub-pixel in the first direction and also includes a partial gap between the blue sub-pixel and the red sub-pixel in the odd-numbered row.
