Description

Pixel arrangement structure, display panel and display device

[0001] Embodiments of the present disclosure relate to a pixel arrangement structure, a display panel, and a display device.

[0002] Organic Light Emitting Diode (OLED) display devices are actively emitting light, and are one of the hot topics in the field of flat panel display research. Compared with liquid crystal displays, OLED display devices have the advantages of low energy consumption, low production cost, self-luminescence, wide viewing angle, and fast response speed. Currently, in the field of flat panel displays such as mobile phones, tablet computers, and digital cameras, OLED display devices have begun to replace traditional liquid crystal displays (LCD).

[0003] OLED is formed by a glass substrate and a thinner organic material film layer arranged on the glass substrate. When current passes through, the organic material will emit light. Therefore, the OLED display panel can greatly save electricity and can be made thinner and lighter.

The second display unit in a pixel group of the pixel arrangement structure includes two second sub-pixels and two third sub-pixels that are respectively shared with four adjacent pixel groups. By borrowing the second sub-pixels and the third sub-pixels in the adjacent pixel groups, the influence of the central color separation bright spots on the human eye can be reduced.

[0040] At present, in order to save production costs, most automobile manufacturers use liquid crystal display products for devices with display functions such as instruments and central control equipment on automobiles. Due to the advantages of organic light emitting diode (OLED) display devices such as low energy consumption, low production cost, self-luminescence, wide viewing angle and fast response speed, many automobile manufacturers have a strong interest in OLED products. There is a good market prospect for using OLED display products in automobile instruments, central control equipment and co-pilot display screens.

[0041] Compared with the combined structure of the traditional liquid crystal display device (LCD) and the liquid crystal display device lifting component (LCF), the design of using the OLED display device as the basis of the vehicle-mounted product to replace the LCD can solve the problems of moiré and insufficient display brightness when displaying images. However, the use of OLED as a vehicle-mounted display device still has the following problems that need to be improved: Considering the particularity of vehicle-mounted products, the pixel structure adopts a real RGB ternary pixel design, which will greatly affect the dark state display effect, so there is an urgent need for a pixel arrangement structure design that can solve the above problems of OLED devices in vehicle-mounted products. In addition, with the rapid development of display technology, consumers have higher and higher requirements for the resolution of display screens. At present, the pixel arrangement method with high resolution is the sub-pixel color borrowing method (SPR, Sub Pixel Rendering). For example, adjacent pixel units will share at least one of the red sub-pixel R and the blue sub-pixel B.

[0042] The inventors of the present disclosure have noticed that a pixel arrangement structure can be designed so that two second sub-pixels and two third sub-pixels included in a second display unit in a pixel group of the pixel arrangement structure are shared with four adjacent pixel groups respectively, and the influence of the central color separation bright spots on the human eye can be reduced by borrowing the second sub-pixels and the third sub-pixels in the adjacent pixel groups. When the display panel with the pixel arrangement structure is used in a vehicle-mounted system, the ambient light will not affect the driver's line of sight during the dark display process, thereby improving driving safety.

[0043] At least one embodiment of the present disclosure provides a pixel arrangement structure, which includes: a plurality of pixel groups arranged in an array, each pixel group includes a first display unit and a second display unit, and the first display unit and the second display unit both include a first sub-pixel, a second sub-pixel and a third sub-pixel that emit light of different colors; the first display unit includes a first sub-pixel, a second sub-pixel and a third sub-pixel, the second display unit includes a first sub-pixel and two second sub-pixels and two third sub-pixels arranged around the first sub-pixel, and the first display unit and the second display unit share a first sub-pixel, a second sub-pixel in the first display unit is one of the two second sub-pixels in the second display unit, and a third sub-pixel in the first display unit is one of the two third sub-pixels in the second display unit; the two second sub-pixels and two third sub-pixels included in the second display unit in a pixel group are respectively shared with four pixel groups adjacent thereto. The pixel arrangement structure makes a pixel group include a total of 5 sub-pixels, each pixel group includes a first display unit and a second display unit, and the three sub-pixels of three colors included in the first display unit are shared with three of the five sub-pixels included in the second display unit, thereby reducing the number of sub-pixels, and the first image display or the second image display can be performed under the drive of different driving circuits. Therefore, the sub-pixels in a pixel group achieve a high-resolution display effect from a low-resolution physical resolution through the principle of borrowing colors, thereby solving the technical problem of limited pixel resolution. In addition, the two second sub-pixels and the two third sub-pixels included in the second display unit in a pixel group are shared with the four adjacent pixel groups respectively, thereby further reducing the number of sub-pixels, making the structure of each pixel group simple, thereby simplifying the structural design of the entire display panel.

[0044] For example, when the pixel arrangement structure is used in the display area of ​​a display product in the automotive field, the influence of the central color separation bright spot on the human eye can be reduced by borrowing sub-pixels, and the ambient light will not affect the driver's vision during the dark display process.

[0045] For example, FIG1 is a schematic diagram of a planar structure of a pixel arrangement structure provided by at least one embodiment of the present disclosure. As shown in FIG1, the pixel arrangement structure 100 includes: a plurality of pixel groups 101 arranged in an array, each pixel group 101 including a first display unit 102 and a second display unit 103. That is, each pixel group 101 is a repeating unit, and the plurality of repeating units are arranged in an array in a first direction X and a second direction Y that intersect each other. As shown in FIG1, the first direction X and the second direction Y intersect, but are not perpendicular to each other, and the angle between the first direction X and the second direction Y is an obtuse angle.

[0046] For example, FIG. 2 is a schematic diagram of a planar structure of a first display unit provided in at least one embodiment of the present disclosure, and FIG. 3 is a schematic diagram of a planar structure of a second display unit provided in at least one embodiment of the present disclosure. As shown in FIG. 2 and FIG. 3, the first display unit 102 and the second display unit 103 both include a first sub-pixel 104, a second sub-pixel 105, and a third sub-pixel 106 that emit light of different colors, except that the number and arrangement of the sub-pixels in the first display unit 102 and the second display unit 103 are different. The first display unit 102 includes a first sub-pixel 104, a second sub-pixel 105, and a third sub-pixel 106, and the second display unit 103 includes a first sub-pixel 104 and two second sub-pixels 105 and two third sub-pixels 106 arranged around the first sub-pixel 104, and the first display unit 102 and the second display unit 103 share a first sub-pixel 104, a second sub-pixel 105 in the first display unit 102 is one of the two second sub-pixels 105 in the second display unit 103, and the first display unit 102 One of the third sub-pixels 106 is one of the two third sub-pixels 106 in the second display unit 103, that is, each pixel group 101 includes 5 sub-pixels, the second display unit 103 includes 5 sub-pixels in one pixel group 101, the first display unit 102 located in the same pixel group 101 as the second display unit 103 includes 3 sub-pixels in one pixel group 101, and the two second sub-pixels 105 and two third sub-pixels 106 included in the second display unit 103 in one pixel group 101 are shared with the four adjacent pixel groups 101 respectively.

[0047] For instance, in one example, the first sub-pixel 104, the second sub-pixel 105 and the third sub-pixel 106 may be a blue sub-pixel B, a green sub-pixel G and a red sub-pixel R, respectively, that is, the first display unit 102 includes a blue sub-pixel B, a green sub-pixel G and a red sub-pixel R, and the second display unit 103 includes a blue sub-pixel B and two green sub-pixels G and two red sub-pixels R arranged around the blue sub-pixel B. Of course, the embodiments of the present disclosure are not limited to this, and the first sub-pixel 104, the second sub-pixel 105 and the third sub-pixel 106 may be a green sub-pixel G, a blue sub-pixel B and a red sub-pixel R, respectively, that is, the first display unit 102 includes a green sub-pixel G, a blue sub-pixel B and a red sub-pixel R, and the second display unit 103 includes a green sub-pixel G and two blue sub-pixels B and two red sub-pixels R arranged around the one green sub-pixel G; it may also be that the first sub-pixel 104, the second sub-pixel 105 and the third sub-pixel 106 are red sub-pixels R, green sub-pixels G and blue sub-pixels B, respectively, that is, the first display unit 102 includes a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B, and the second display unit 103 includes a red sub-pixel R and two blue sub-pixels B and two green sub-pixels G arranged around the one red sub-pixel R.

[0048] For example, as shown in Figures 2 and 3, the area of ​​each first sub-pixel 104 is larger than the area of ​​each second sub-pixel 105, and larger than the area of ​​each third sub-pixel 106. Since the blue sub-pixel B has the lowest luminous brightness, in order to ensure the uniformity of the white light displayed by the final display panel, it is usually necessary to define the first sub-pixel 104 with the largest area as the blue sub-pixel B, and one of the second sub-pixel 105 and the third sub-pixel 106 with smaller areas as the red sub-pixel R, and the other as the green sub-pixel G.

[0049] For example, as shown in FIG. 2 , the first display unit 102 is shown in a plane formed by a horizontal direction and a direction perpendicular to the horizontal plane, the third sub-pixel 106 is located on the horizontal plane, the plane where the first sub-pixel 104 is located is perpendicular to the horizontal plane, and the plane where the second sub-pixel 105 is located is perpendicular to the horizontal plane. The first sub-pixel 104, the second sub-pixel 105, and the third sub-pixel 106 included in the first display unit 102 are half-rectangular parallelepiped structures. The plane where the first sub-pixel 104 is located, the plane where the second sub-pixel 105 is located, and the plane where the third sub-pixel 106 is located intersect at a point, the plane where the first sub-pixel 104 is located and the plane where the second sub-pixel 105 is located share an edge, the plane where the second sub-pixel 105 is located and the plane where the third sub-pixel 106 is located share an edge, and the plane where the first sub-pixel 104 is located and the plane where the third sub-pixel 106 is located also share an edge, but the embodiments of the present disclosure are not limited thereto.

[0050] It should be noted that, although in FIG. 1, FIG. 2 and FIG. 3, a box is set around the first sub-pixel 104, the second sub-pixel 105 and the third sub-pixel 106, in fact, these boxes are virtual boxes, in order to more clearly show the relationship between the sub-pixels. For example, a side shared by the plane where the first sub-pixel 104 is located and the plane where the second sub-pixel 105 is located is a side shared by the box surrounding the first sub-pixel 104 and the box surrounding the second sub-pixel 105. A side shared by the plane where the second sub-pixel 105 is located and the plane where the third sub-pixel 106 is a side shared by the box surrounding the second sub-pixel 105 and the box surrounding the third sub-pixel 106. A side shared by the plane where the first sub-pixel 104 is located and the plane where the third sub-pixel 106 is a side shared by the box surrounding the first sub-pixel 104 and the box surrounding the third sub-pixel 106.

[0051] For example, when the pixel driving circuit drives the first display unit 102 to display, a first sub-pixel 104, a second sub-pixel 105 and a third sub-pixel 106 constitute a pixel point, and perform conventional R, G, B three primary colors display.

[0052] For example, the second display unit 103 adopts Pentile display, which is a method of reducing the number of sub-pixels by sharing sub-pixels between adjacent pixels, thereby achieving the effect of simulating high resolution with low resolution, and then achieving the effect of higher visual brightness of the viewer under the same brightness. In addition, this pixel arrangement structure also makes the cost of manufacturing the display panel lower. When the pixel driving circuit drives the second display unit 103 to display, a pixel of the Pentile display will "borrow" another color of the pixel adjacent to it to form three primary colors. Pentile arrangement appeared with the birth of OLED display materials. For actively luminous OLED display devices, OLED RGB corresponds to organic materials that emit red light, organic materials that emit green light, and organic materials that emit blue light. Current displays have high requirements for resolution, which requires each luminescent material to be made very small and integrated with high density, which is difficult in terms of process and has high production costs. Using Pentile arrangement, adjacent display units use sub-pixel borrowing, which can make the area of ​​the luminous layer of each sub-pixel larger, thereby reducing the process difficulty in the preparation process and reducing production costs. In addition, the Pentile display has a higher pixel density, so it can better display high-resolution images and colorful images, and can also display images clearly under direct sunlight.

[0053] For example, FIG4 is a schematic diagram of a planar structure of another first display unit provided by at least one embodiment of the present disclosure. As shown in FIG4, the first display unit 102 is shown in a plane formed by a horizontal direction and a direction perpendicular to the horizontal plane. The third sub-pixel 106 is located on the horizontal plane. The plane where the first sub-pixel 104 is located is perpendicular to the horizontal plane. The plane where the second sub-pixel 105 is located is perpendicular to the horizontal plane. The plane where the first sub-pixel 104 is located, the plane where the second sub-pixel 105 is located, and the plane where the third sub-pixel 106 is located intersect at a point. The plane where the first sub-pixel 104 is located and the plane where the second sub-pixel 105 is located share an edge. The plane where the first sub-pixel 104 is located and the plane where the third sub-pixel 106 is located also share an edge. However, the plane where the second sub-pixel 105 is located and the plane where the third sub-pixel 106 is located do not share an edge. However, the embodiment of the present disclosure is not limited thereto.

[0054] For example, FIG. 5 shows the connection structure of the geometric centers of the first sub-pixel, the second sub-pixel, and the third sub-pixel included in the first display unit in FIG. 2. As shown in FIG. 5, the triangle ABC formed by connecting the geometric center A of a first sub-pixel 104, the geometric center B of a second sub-pixel 105, and the geometric center C of a third sub-pixel 106 included in the first display unit 102 is an acute triangle. For example, <ABC, <ACB, and <BAC in this acute triangle are all acute angles, that is, all less than 90o. This kind of setting can make the structure of the first display unit 102 more compact, making the display screen more uniform when the finally formed first display unit 102 is displaying.

[0055] For example, as shown in FIG. 5, in a first display unit 102, there is a first pitch L1 between the first sub-pixel 104 and the second sub-pixel 105, a second pitch L2 between the second sub-pixel 105 and the third sub-pixel 106, and a third pitch L3 between the first sub-pixel 104 and the third sub-pixel 106. The first pitch L1, the second pitch L2, and the third pitch L3 are all equal. This can make the distance between any two of the first sub-pixel 104, the second sub-pixel 105, and the third sub-pixel 106 equal, and can further ensure the uniformity of the display screen when the first display unit 102 is displaying.

[0056] For example, FIG. 6 shows the connection structure of the geometric centers of a first sub-pixel, two second sub-pixels, and two third sub-pixels included in the second display unit in FIG. 3. As shown in FIG. 6, the quadrilateral formed by connecting the geometric centers M, N of the two second sub-pixels 105 and the geometric centers P, Q of the two third sub-pixels 106 included in the second display unit 103 is a parallelogram MNPQ, and the geometric center K of a first sub-pixel 104 included in the second display unit 103 coincides with the intersection of the two diagonals MN and PQ of the parallelogram MNPQ. This kind of structural design makes the structure of a first sub-pixel, two second sub-pixels, and two third sub-pixels included in the second sub-pixel 105 more compact, so that the display screen is more uniform when the finally formed second display unit 103 is displaying, and it can make the pixel arrangement structure adopt as few sub-pixels as possible to realize two different display modes.

[0057] For example, as shown in FIG. 6, in the second display unit 103, there is a fourth pitch L4 between the first sub-pixel 104 and any second sub-pixel 105, a fifth pitch L5 between the second sub-pixel 105 and the adjacent third sub-pixel 106, and a sixth pitch L6 between the first sub-pixel 104 and any third sub-pixel 106. The fourth pitch L4, the fifth pitch L5, and the sixth pitch L6 are all equal. This kind of design can make the display screen more uniform when the second display unit 103 is displaying an image.

[0058] For example, in one example, in a pixel group 101, the two second sub-pixels 105 included in the second display unit 103 are equal in area and shape, and the two second sub-pixels 105 are arranged opposite to each other on both sides of the first sub-pixel 104. For example, one of the two second sub-pixels 105 is on the left side of the first sub-pixel 104, and the other is on the right side of the first sub-pixel 104. The minimum distance between the second sub-pixel 105 located on the left side of the first sub-pixel 104 and the first sub-pixel 104 is equal to the minimum distance between the second sub-pixel 105 located on the right side of the first sub-pixel 104 and the first sub-pixel 104. The two third sub-pixels 106 have equal areas and the same shape, and the two third sub-pixels 106 are arranged opposite to each other on both sides of the first sub-pixel 104. For example, one of the two third sub-pixels 106 is on the upper side of the first sub-pixel 104, and the other is on the lower side of the first sub-pixel 104. The minimum distance between the third sub-pixel 106 located on the upper side of the first sub-pixel 104 and the first sub-pixel 104 is equal to the minimum distance between the third sub-pixel 106 located on the lower side of the first sub-pixel 104 and the first sub-pixel 104.

[0059] For example, in the structure shown in FIG6, the first sub-pixel 104 is a blue sub-pixel B, the second sub-pixel 105 is one of a red sub-pixel R and a green sub-pixel B, and the third sub-pixel 106 is the other of a red sub-pixel R and a green sub-pixel G. For example, the first sub-pixel 104 is a blue sub-pixel B, the second sub-pixel 105 is a red sub-pixel R, and the third sub-pixel 106 is a green sub-pixel G. The second sub-pixel 105 located on the left side of the first sub-pixel 104 in the pixel group shown in FIG6 is shared with the adjacent pixel group located on the left side of the pixel group, and the second sub-pixel 105 located on the right side of the first sub-pixel 104 in the pixel group shown in FIG6 is shared with the adjacent pixel group located on the right side of the pixel group. The third sub-pixel 106 located on the upper side of the first sub-pixel 104 in the pixel group shown in FIG6 is shared with the adjacent pixel group located on the upper side of the pixel group, and the third sub-pixel 105 located on the lower side of the first sub-pixel 104 in the pixel group shown in FIG6 is shared with the adjacent pixel group located on the lower side of the pixel group.

[0060] For example, in combination with FIG. 1 and FIG. 6 , a plurality of pixel groups 101 are arranged in an array in a first direction X and a second direction Y, the first direction X and the second direction Y intersect and are not perpendicular, and a plurality of geometric centers K of the second display units 103 are arranged in an array in the first direction X and the second direction Y.

[0061] For example, in the structure shown in FIG6 , the planar shape of the first sub-pixel 104 is a rectangle, the planar shapes of the two second sub-pixels 105 and the two third sub-pixels 106 are all parallelograms, the area of ​​the first sub-pixel 104 is larger than the area of ​​any second sub-pixel 105, and the area of ​​the first sub-pixel 104 is larger than the area of ​​any third sub-pixel 106, and the shape of the arrangement structure of the five sub-pixels forming the second display unit is an irregular hexagon.

[0062] For example, Figure 7 is a schematic diagram of the planar structure of another second display unit provided by at least one embodiment of the present disclosure. As shown in Figure 7, the planar shape of the first sub-pixel 104, the planar shape of the second sub-pixel 105, and the planar shape of the third sub-pixel 106 are all rectangular. The two second sub-pixels 105 included in the second display unit 103 are equal in area and shape, and are arranged opposite to each other on both sides of the first sub-pixel 104. For example, one of the two second sub-pixels 105 is on the left side of the first sub-pixel 104, and the other is on the right side of the first sub-pixel 104. The minimum distance between the second sub-pixel 105 on the left and the first sub-pixel 104 is equal to the minimum distance between the second sub-pixel 105 on the right and the first sub-pixel 104. The two third sub-pixels 106 have the same area and the same shape, and are arranged in pairs on both sides of the first sub-pixel 104. For example, one of the two third sub-pixels 106 is on the upper side of the first sub-pixel 104, and the other is on the lower side of the first sub-pixel 104. The minimum distance between the third sub-pixel 106 located on the upper side and the first sub-pixel 104 is equal to the minimum distance between the third sub-pixel 106 located on the lower side and the first sub-pixel 104. The length of the long side of the first sub-pixel 104 is greater than the length of the long side of the third sub-pixel 106, and the length of the long side of the third sub-pixel 106 is greater than the length of the long side of the second sub-pixel 105. The length of the short side of the first sub-pixel 104 is greater than the length of the short side of the second sub-pixel 105, and the length of the short side of the second sub-pixel 105 is greater than the length of the short side of the third sub-pixel 106. As can be seen from FIG. 7, the area of ​​the first sub-pixel 104 is greater than the area of ​​each third sub-pixel 106, and the area of ​​each third sub-pixel 106 is greater than the area of ​​each second sub-pixel 105. In Figure 7, there is a fourth spacing L4 between the first sub-pixel 104 and any second sub-pixel 105, there is a fifth spacing L5 between the second sub-pixel 105 and the third sub-pixel 106 adjacent thereto, and there is a sixth spacing L6 between the first sub-pixel 104 and any third sub-pixel 106. The fourth spacing L4, the fifth spacing L5 and the sixth spacing L6 are all equal. This design can make the picture displayed by the second display unit 103 more uniform when displaying.

[0063] For example, FIG8 is a schematic diagram of a planar structure of another second display unit provided by at least one embodiment of the present disclosure. As shown in FIG8 , the planar shape of the first sub-pixel 104 is a rhombus, the planar shapes of the second sub-pixel 105 and the planar shapes of the third sub-pixel 106 are both parallelograms, and the maximum distance between the opposite sides of the first sub-pixel 104 is greater than the maximum distance between the opposite sides of the second sub-pixel 105, and the maximum distance between the opposite sides of the second sub-pixel 105 is greater than the maximum distance between the opposite sides of the third sub-pixel 106. It can also be seen from FIG8 that the area of ​​the first sub-pixel 104 is greater than the area of ​​each third sub-pixel 106, and the area of ​​each third sub-pixel 106 is greater than the area of ​​each second sub-pixel 105. In Figure 8, there is a fourth spacing L4 between the first sub-pixel 104 and any second sub-pixel 105, there is a fifth spacing L5 between the second sub-pixel 105 and the third sub-pixel 106 adjacent thereto, and there is a sixth spacing L6 between the first sub-pixel 104 and any third sub-pixel 106. The fourth spacing L4, the fifth spacing L5 and the sixth spacing L6 are all equal. This design can make the picture displayed by the second display unit 103 more uniform when displaying.

[0064] For example, in the pixel arrangement structure provided in at least one embodiment of the present disclosure, the planar shapes of the first sub-pixel 104, the second sub-pixel 105 and the third sub-pixel 106 may all include arc-shaped portions, which make the edges of the pixel openings smoother, thereby reducing the jaggedness of the displayed image.

[0065] For example, FIG9 is a schematic diagram of a planar structure of another second display unit provided by at least one embodiment of the present disclosure. As shown in FIG9, the planar shapes of a first sub-pixel 104, two second sub-pixels 105, and two third sub-pixels 106 are all ellipses, and the short diameter of the ellipse corresponding to the first sub-pixel 104 is greater than the short diameter of the ellipse corresponding to the second sub-pixel 105 and the short diameter of the ellipse corresponding to the third sub-pixel 106, and the short diameter of the ellipse corresponding to the second sub-pixel 105 is greater than or equal to the short diameter of the ellipse corresponding to the third sub-pixel 106; the long diameter of the ellipse corresponding to the first sub-pixel 104 is greater than or equal to the long diameter of the ellipse corresponding to the third sub-pixel 106, and the long diameter of the ellipse corresponding to the third sub-pixel 106 is greater than the long diameter of the ellipse corresponding to the second sub-pixel 105. Setting the planar shapes of the first sub-pixel 104, the two second sub-pixels 105, and the two third sub-pixels 106 to ellipses can make the edge of each pixel opening smoother, thereby reducing the jagged feeling of the displayed image. It can also be seen from FIG9 that the area of ​​the first sub-pixel 104 is larger than the area of ​​each third sub-pixel 106, and the area of ​​each third sub-pixel 106 is larger than the area of ​​each second sub-pixel 105. In FIG9, there is a fourth spacing L4 between the first sub-pixel 104 and any second sub-pixel 105, a fifth spacing L5 between the second sub-pixel 105 and the third sub-pixel 106 adjacent thereto, and a sixth spacing L6 between the first sub-pixel 104 and any third sub-pixel 106. The fourth spacing L4, the fifth spacing L5, and the sixth spacing L6 are all equal. This design can make the second display unit 103 display a more uniform picture when displaying.

[0066] For example, FIG10 is a schematic diagram of a planar structure of another second display unit provided by at least one embodiment of the present disclosure. As shown in FIG10, the planar shapes of a first sub-pixel 104, two second sub-pixels 105, and two third sub-pixels 106 are all circular, and the diameter of the circle corresponding to the first sub-pixel 104 is greater than the diameter of the circle corresponding to the second sub-pixel 105, and the diameter of the circle corresponding to the second sub-pixel 105 is greater than the diameter of the circle corresponding to the third sub-pixel 106, that is, the area of ​​the first sub-pixel 104 is greater than the area of ​​the second sub-pixel 105, and the area of ​​the second sub-pixel 105 is greater than the area of ​​the third sub-pixel 106. As shown in FIG10, there is a fourth spacing L4 between the first sub-pixel 104 and any second sub-pixel 105, and there is a fifth spacing L5 between the second sub-pixel 105 and the third sub-pixel 106 adjacent thereto. Any two of the fourth spacing L4, the fifth spacing L5, and the sixth spacing L6 are not equal.

[0067] For example, in the embodiment shown in FIG. 10 , a sixth interval L6 is provided between the first sub-pixel 104 and any third sub-pixel 106 , the fifth interval L5 is greater than the fourth interval L4 , and the fourth interval L4 is greater than the sixth interval L6 .

[0068] Of course, the embodiments of the present disclosure are not limited thereto. In the structure shown in FIG. 10 , any two of the fourth interval L4 , the fifth interval L5 , and the sixth interval L6 may also be equal.

[0069] It should be noted that, in the embodiment of the present disclosure, the embodiment in which the planar shapes of the first sub-pixel 104, the second sub-pixel 105 and the third sub-pixel 106 all include arc-shaped portions is not limited to the embodiments shown in Figures 9 and 10 above, as long as the planar shapes of the first sub-pixel 104, the second sub-pixel 105 and the third sub-pixel 106 all include arc-shaped portions. For example, the planar shapes of the first sub-pixel 104, the second sub-pixel 105 and the third sub-pixel 106 all include fan-shaped portions, arc-shaped portions or semicircular portions, etc.

[0070] For example, in the embodiments shown in Figures 6 to 10, the geometric centers M and N of the two second sub-pixels 105 included in the second display unit 103, and the geometric centers P and Q of the two third sub-pixels 106 form a quadrilateral MNPQ, and the geometric center K of a first sub-pixel 104 included in the second display unit 103 coincide with the intersection of the two diagonals MN and PQ of the parallelogram MNPQ.

[0071] For example, in the embodiments shown in FIGS. 6 to 10, the second display unit 103 includes a first sub-pixel 104, two second sub-pixels 105, and two third sub-pixels 106 located in a special-shaped hexagon. For example, FIG. 11 is a schematic diagram of the structure of a special-shaped hexagon in at least one embodiment of the present disclosure. The special-shaped hexagon is shown in FIG. 11, and two adjacent sides in the special-shaped hexagon are perpendicular to each other. For example, setting the outer contour of each pixel group to a special-shaped hexagon can make the overall structure of the pixel group uniform, and at the same time, the three primary colors of red, green, and blue can be more evenly distributed, so that the display effect is stable.

[0072] At least one embodiment of the present disclosure further provides a display panel. FIG12 is a schematic diagram of a planar structure of a display panel provided by at least one embodiment of the present disclosure. As shown in FIG12, the display panel 200 includes a display area 201 and a non-display area 202. The display area 201 is provided with a plurality of pixel openings 203. The plurality of pixel openings 203 have a pixel arrangement structure 100 as in any of the above embodiments. Peripheral wiring is provided in the non-display area 202. The display panel 200 can have a high resolution and a high display PPI by sharing a sub-pixel in a pixel group with a sub-pixel in an adjacent pixel group. When a pixel group having the pixel arrangement structure is applied to a display panel, the edge of the display panel is displayed more uniformly and with less jaggedness. Moreover, when driven by different driving circuits, the display can be respectively displayed by the first display unit and the second display unit.

[0073] At least one embodiment of the present disclosure further provides a display device. For example, FIG13 is a block diagram of a display device provided by at least one embodiment of the present disclosure. As shown in FIG13 , the display device 300 includes a display panel 200 in any of the above embodiments and a driving circuit 400 for providing a driving signal to the display panel 200. The display device may be any product or component with a display function, such as a mobile phone, a tablet computer, a television, a monitor, a laptop computer, a digital photo frame, a navigator, or the like.

[0075] (1) In at least one embodiment of the present disclosure, a pixel arrangement structure is provided, in which two second sub-pixels and two third sub-pixels included in a second display unit of a pixel group are respectively shared with four adjacent pixel groups. By borrowing the second sub-pixels and the third sub-pixels in the adjacent pixel groups, the influence of the central color separation bright spots on the human eye can be reduced. When a display panel having the pixel arrangement structure is used in a vehicle-mounted system, the ambient light will not affect the driver's vision during the dark display process.

[0076] (2) In the pixel arrangement structure provided by at least one embodiment of the present disclosure, the three sub-pixels of three colors included in the first display unit and three of the five sub-pixels included in the second display unit are shared, thereby reducing the number of sub-pixels, and the first image display or the second image display can be performed under the drive of different driving circuits. Therefore, the sub-pixels in a pixel group can achieve a high-resolution display effect from a low-resolution physical resolution through the principle of borrowing colors, thereby solving the technical problem of limited pixel resolution.
