Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a display panel, a display module and an electronic device. Background Art

[0002] In the field of naked-eye 3D display, the relatively mature display solution is to directly attach a spectroscopic device to the display screen. The light emitted by the sub-pixels on the display screen is staggered in space after being acted upon by the spectroscopic device to form viewpoints. Each viewpoint contains different parallax information, which is fused into a 3D picture with a stereoscopic effect after entering the human eye. Currently, naked-eye 3D has the problem of poor display effect. Summary of the invention

[0003] The embodiments of the present application provide a display panel, a display module and an electronic device to solve the technical problem of poor naked-eye 3D display effect in the prior art.

[0004] In a first aspect, an embodiment of the present application provides a display panel, the display panel includes a pixel unit, the pixel unit includes N*2M sub-pixels, the N*2M sub-pixels have N colors in total, the N*2M sub-pixels are arranged into N first sub-pixel groups extending along a first direction and 2M second sub-pixel groups extending along a second direction, N and M are both positive integers, N≥3, M≥2, and the first direction and the second direction intersect each other;

[0005] The arrangement of N*2M sub-pixels in a pixel unit satisfies the following rules:

[0006]

[0007] Wherein, i and j are both positive integers, (i, j) represents a subpixel located in the i-th first subpixel group and the j-th second subpixel group in the pixel unit; C(i, j) = 0, 1, to N-1, representing N colors of the subpixel.

[0008] The pixel unit in the display panel provided in the embodiment of the present application includes sub-pixels of N colors, and the arrangement of N*2M sub-pixels in the pixel unit is designed so that the sub-pixels of the same color in the display panel are arranged in a zigzag shape. When applied to naked-eye 3D display products, the arrangement direction of the sub-pixels of the same color is not parallel to the bonding direction of the spectroscopic device, so that the interference effect between the periodic arrangement of the spectroscopic device and the periodic arrangement of the sub-pixels can be broken, thereby weakening or even eliminating the moiré caused by the periodic arrangement of the spectroscopic device and the periodic arrangement of the sub-pixels, thereby improving the depth of field of the naked-eye 3D display and enhancing the viewing experience.

[0009] In some embodiments, the pixel unit includes a light-emitting area and a non-light-emitting area between adjacent light-emitting areas, and one sub-pixel includes one light-emitting area; the spacing between two adjacent light-emitting areas along the first direction is d1, there is a misalignment between two adjacent light-emitting areas along the second direction, and the length of the misalignment distance between the two along the first direction is l1, l1≤d1; or, the spacing between two adjacent light-emitting areas along the second direction is d2, there is a misalignment between two adjacent light-emitting areas along the first direction, and the length of the misalignment distance between the two along the second direction is l2, l2≤d2. When the display panel provided by this embodiment is used in a naked-eye display product, it can further break the interference effect between the periodic arrangement of the light-splitting device and the periodic arrangement of the sub-pixels, thereby further eliminating the moiré caused by the periodic arrangement of the light-splitting device and the periodic arrangement of the sub-pixels, improving the depth of field of the naked-eye 3D display and enhancing the viewing experience.

[0010] In some embodiments, the sub-pixel includes a light-emitting area; at least one edge of the light-emitting area extends along the first direction, and / or at least one edge of the light-emitting area extends along the second direction. Such a configuration can facilitate the design of the bonding direction of the spectrometer when applied. The bonding direction of the spectrometer is parallel to the first direction, or parallel to the second direction, or there is a small angle between the bonding direction of the spectrometer and the first direction (or the second direction), which can avoid mixing other viewpoint sub-pixels into the sampling line of the spectrometer and causing the overlap area between adjacent viewpoints to increase, thereby reducing crosstalk between viewpoints and improving the naked eye 3D display effect. Optionally, the shape of the light-emitting area can be rectangular or triangular.

[0011] In some embodiments, the first direction and the second direction are perpendicular to each other. In this embodiment, the sub-pixels in the pixel unit are arranged in a relatively regular array, which can facilitate the periodic arrangement design of the pixel unit to adapt to the shape of the display panel.

[0012] In some embodiments, there is an acute angle between the first direction and the second direction. In this embodiment, the sub-pixels in the pixel unit are arranged roughly in an inclined shape, so that the extension direction of the pixel unit can be inclined relative to the edge of the display panel, and the horizontal screen display effect and the vertical screen display effect of the 3D display can be balanced, and the crosstalk between the horizontal screen viewing and the vertical screen viewing can be reduced, so that the 3D display effect with a large depth of field and high stereoscopic degree can be achieved in both the horizontal screen mode and the vertical screen mode.

[0013] In some embodiments, the acute angle between the first direction and the second direction is 45°. When used in 3D display products, it can ensure that the angle between the bonding direction of the light splitting device and the horizontal direction is the same in the horizontal display mode and the vertical display mode, so that a balance can be achieved between the horizontal display effect and the vertical display effect, and the crosstalk between horizontal and vertical viewing can be reduced, so that a 3D display effect with a large depth of field and high stereoscopic degree can be achieved in both the horizontal and vertical modes.

[0014] In some embodiments, the display panel includes a first edge extending along a third direction and a second edge extending along a fourth direction, the third direction and the fourth direction are perpendicular to each other; at least one of the first direction and the second direction has a non-zero angle with both the third direction and the fourth direction. In this embodiment, the display panel is rectangular, and at least one of the first direction and the second direction has a non-zero angle with the edge of the display panel, so that the extension direction of the pixel unit can be tilted relative to the edge of the display panel, and the horizontal screen display effect and the vertical screen display effect of the 3D display can be balanced, and the crosstalk between horizontal and vertical screen viewing can be reduced, so that the 3D display effect with large depth of field and high stereoscopic degree can be achieved in both horizontal and vertical modes.

[0015] In the second aspect, based on the same application concept, the embodiment of the present application further provides a display module, the display module includes a stacked display panel and a spectroscopic device; the display panel is the display panel provided by any embodiment of the present application. The display module provided by the embodiment of the present application can achieve that the arrangement direction of sub-pixels of the same color is not parallel to the bonding direction of the spectroscopic device, so that the interference effect between the periodic arrangement of the spectroscopic device and the periodic arrangement of the sub-pixels can be broken, thereby weakening or even eliminating the moiré caused by the periodic arrangement of the spectroscopic device and the periodic arrangement of the sub-pixels, improving the depth of field of the naked-eye 3D display and enhancing the viewing experience.

[0016] In some embodiments, the sub-pixel includes a light-emitting area, and the angle between at least one side of the light-emitting area and the alignment direction of the light-splitting device is α, 0°≤α≤5°. There may be a smaller angle between the alignment direction of the light-splitting device and one side of the light-emitting area of ​​the sub-pixel sp. In practice, the method of rotating the light-splitting device may be used to determine the optimal angle α to ensure the best effect of reducing the influence of moiré.

[0017] In some embodiments, the spectroscopic device includes a grating, and the fitting direction is the extension direction of the slits of the grating; or, the spectroscopic device includes a lens, and the fitting direction is the extension direction of the optical axis of the lens.

[0018] In some embodiments, the light-emitting area includes a first side, and the angle between the first side and the bonding direction of the spectrometer is α; the first side extends along the first direction, or the first side extends along the second direction. When the light-emitting area is rectangular, the first side can be the long side of the light-emitting area, or the first side can be the short side of the light-emitting area. Such a setting can prevent the mixing of other viewpoint sub-pixels into the sampling line of the spectrometer, resulting in an increase in the overlapping area between adjacent viewpoints, causing crosstalk between viewpoints.

[0019] In a third aspect, based on the same inventive concept, an embodiment of the present application further provides an electronic device, comprising a display module provided by any embodiment of the present application.

[0020] The display panel, display module and electronic device provided by the embodiments of the present application have the following beneficial effects: the pixel unit in the display panel includes sub-pixels of N colors, and the arrangement of N*2M sub-pixels in the pixel unit is designed so that the sub-pixels of the same color in the display panel are arranged in a zigzag shape. When applied to naked-eye 3D display products, the arrangement direction of the sub-pixels of the same color is not parallel to the bonding direction of the spectroscopic device, so that the interference effect between the periodic arrangement of the spectroscopic device and the periodic arrangement of the sub-pixels can be broken, thereby weakening or even eliminating the moiré caused by the periodic arrangement of the spectroscopic device and the periodic arrangement of the sub-pixels, thereby improving the depth of field of the naked-eye 3D display and enhancing the viewing experience.

[0035] In the current naked-eye 3D technology, the spectroscopic devices attached to the display panel mainly include lenses or gratings. There are two main limiting factors in this technology that affect the display effect of naked-eye 3D.

[0036] The first limiting factor is the restrictive relationship between moiré and crosstalk. Interference effects will occur between the periodically arranged stripes of the spectroscopic device and the periodically arranged sub-pixels of the display panel, causing obvious moiré. The presence of moiré will damage the display effect of naked-eye 3D, causing discomfort, weakened stereoscopic effect and other adverse effects. Taking the spectroscopic device as a cylindrical lens as an example, when the cylindrical lens and the display panel are bonded, the method of rotating the cylindrical lens is often used to find the bonding angle with the slightest moiré to achieve the purpose of eliminating moiré. However, too large a lens bonding angle will introduce too much crosstalk between viewpoints. The larger the angle between the optical axis of the lens and the sub-pixel, the larger the area of ​​other viewpoint sub-pixels mixed in the lens sampling line, resulting in an increase in the overlapping area between adjacent viewpoints and an increase in crosstalk between viewpoints. Large crosstalk between viewpoints will limit the depth of field range of naked-eye 3D display, and images exceeding the depth of field range will have adverse phenomena such as blur and ghosting. Therefore, it can be said that in the prior art, the display panel superimposed with a spectroscopic device to achieve naked-eye 3D display eliminates moiré at the expense of the stereoscopic effect.

[0037] The second limiting factor is the restrictive relationship between the horizontal screen display effect and the vertical screen display effect. Taking a conventional rectangular display panel, such as a mobile phone, as an example, the default display mode of the mobile phone is generally the vertical screen display mode. When you want to play games, you can rotate the phone 90 degrees and switch to the horizontal screen display mode. From the description of the first limiting factor, it can be seen that the larger the lens fitting angle, the greater the crosstalk between viewpoints, and the worse the stereoscopic display effect. However, for horizontal and vertical screen displays, the lens fitting angles are complementary. That is, if the crosstalk of the horizontal screen display is small, the crosstalk of the vertical screen display must be large, and vice versa. At present, the naked-eye 3D display made with conventional display panels cannot achieve a good stereoscopic display effect in both horizontal and vertical screens. The display effect in another viewing direction can only be improved at the expense of the stereoscopic display effect in one viewing direction.

[0038] It can be seen that eliminating the restrictive relationship between moiré and crosstalk, and the restrictive relationship between horizontal screen display effect and vertical screen display effect is currently the key to improving naked-eye 3D display effect and product competitiveness.

[0039] In order to solve the problems of the prior art, the present application provides a display panel, designs the pixel arrangement in the display area, arranges the sub-pixels of the same color into a zigzag shape, and is applied to naked-eye 3D display products to eliminate the moiré caused by the interference between the periodic arrangement of the spectroscopic device and the periodic arrangement of the sub-pixels, thereby improving the depth of field of the naked-eye 3D display and the viewing experience. In the prior art, sub-pixels are generally arranged in a horizontal and vertical array, and the present application further sets the arrangement direction of the sub-pixels to be tilted relative to the vertical direction, wherein the vertical direction refers to the vertical direction when the user holds the display panel. In this way, it is possible to balance the horizontal and vertical display effects of the 3D display, reduce the crosstalk between horizontal and vertical viewing, and achieve a 3D display effect with a large depth of field and high stereoscopic degree in both horizontal and vertical modes.

[0040] An embodiment of the present application provides a display panel, the display panel includes a pixel unit, the pixel unit includes N*2M sub-pixels, and the N*2M sub-pixels have a total of N colors. The sub-pixels in the present application include organic light-emitting devices, or inorganic light-emitting devices, or liquid crystal molecules. The N*2M sub-pixels in the pixel unit are arranged into N first sub-pixel groups extending along a first direction and 2M second sub-pixel groups extending along a second direction, N and M are both positive integers, N≥3, M≥2, and the first direction and the second direction intersect each other;

[0041] The arrangement of N*2M sub-pixels in a pixel unit satisfies the following rules:

[0042]

[0043] Wherein, i and j are both positive integers, (i, j) represents the sub-pixel located in the i-th first sub-pixel group and in the j-th second sub-pixel group in the pixel unit; C(i, j) = 0, 1, to N-1, representing N colors of the sub-pixel. mod is the remainder function.

[0044] Figure 1 A schematic diagram of a display panel provided in an embodiment of the present application. Figure 1 Taking N=3 and M=3 as an example, a plurality of sub-pixels at local positions in the display area are illustrated.

[0045] like Figure 1 As shown, the display panel includes a pixel unit 10, and the area where the multiple pixel units 10 are located is divided by dotted lines that cross horizontally and vertically. The pixel unit 10 includes 3*6 sub-pixels sp, and the pixel unit 10 includes three color sub-pixels sp, namely, a first sub-pixel sp1, a second sub-pixel sp2, and a third sub-pixel sp3 with different colors. Optionally, the first sub-pixel sp1, the second sub-pixel sp2, and the third sub-pixel sp3 are respectively one of the three colors of red, green, and blue. The pixel unit 10 includes three first sub-pixel groups Z1 extending along a first direction a and six second sub-pixel groups Z2 extending along a second direction b, and the first direction a and the second direction b intersect each other.

[0046] Figure 1 In the figure, the first direction a and the second direction b are perpendicular to each other, wherein at least one side of the sub-pixel sp is parallel to the first direction a or parallel to the second direction b. The sub-pixel sp includes a light-emitting area (i.e., a light-emitting region), Figure 1 The shape of the sub-pixel sp shown in the figure is the shape of the light-emitting area, so it can be said that at least one side of the light-emitting area of ​​the sub-pixel sp is parallel to the first direction a or parallel to the second direction b. In some embodiments, the light-emitting area of ​​the sub-pixel sp may include two types of sides, one side is parallel to the first direction a, and the other side is parallel to the second direction b. Figure 1 The sub-pixel sp is illustrated as a rectangle, the long side of the sub-pixel sp is parallel to the first direction a, and the short side of the sub-pixel sp is parallel to the second direction b, wherein the length of the long side is greater than the length of the short side. Optionally, the ratio of the length of the long side to the short side of the sub-pixel sp is 3:1. In other words, the light-emitting area of ​​the sub-pixel sp is a rectangle, the long side of the light-emitting area is parallel to the first direction a, and the short side of the light-emitting area is parallel to the second direction b. In other embodiments, the shape of the sub-pixel sp is a triangle, and one side of the sub-pixel sp is parallel to the first direction a or parallel to the second direction b. The case where the shape of the sub-pixel sp is a triangle will be schematically illustrated in the following embodiments.

[0047] The present application provides a sub-pixel sp arrangement rule in the pixel unit 10, C(i, j)=0, 1, 2, representing three colors of the sub-pixel sp, wherein C(i, j)=0 represents the color of the first sub-pixel sp1, C(i, j)=1 represents the color of the second sub-pixel sp2, and C(i, j)=2 represents the color of the third sub-pixel sp3.

[0048] In the pixel unit 10, from top to bottom, they are the 1st second sub-pixel group Z2, the 2nd second sub-pixel group Z2, to the 6th second sub-pixel group Z2, and from left to right, they are the 1st first sub-pixel group Z1, the 2nd first sub-pixel group Z1, and the 3rd first sub-pixel group Z1.

[0049] In the pixel unit 10, the arrangement of the sub-pixels sp in the first to third second sub-pixel groups Z2 follows formula ①: C(i,j)=mod((mod(j-1,N)+i-1),N), N=3, M=3. For example:

[0050] (1, 1) represents the sub-pixel sp located in the first first sub-pixel group Z1 and the first second sub-pixel group Z2 in the pixel unit 10. According to formula ①, C(1, 1) = 0, that is, the first sub-pixel sp1 is at the position (1, 1).

[0051] (2, 1) represents the sub-pixel sp located in the second first sub-pixel group Z1 and the first second sub-pixel group Z2 in the pixel unit 10. According to formula ①, C(2, 1) = 1, that is, the second sub-pixel sp2 is at the position (2, 1).

[0052] (3, 1) represents the sub-pixel sp located in the third first sub-pixel group Z1 and the first second sub-pixel group Z2 in the pixel unit 10. According to formula ①, C(3, 1)=2, that is, the third sub-pixel sp3 is at the position (3, 1).

[0053] (2, 2) represents the sub-pixel sp located in the second first sub-pixel group Z1 and the second second sub-pixel group Z2 in the pixel unit 10. According to formula ①, C(2, 2)=2, that is, the third sub-pixel sp3 is at the position (2, 2).

[0054] (1, 3) represents the sub-pixel sp located in the first sub-pixel group Z1 and the third second sub-pixel group Z2 in the pixel unit 10. According to formula ①, C(1, 3)=2, that is, the third sub-pixel sp3 is at the position (1, 3).

[0055] In the pixel unit 10, the arrangement of the sub-pixels sp in the 4th to 6th second sub-pixel groups Z2 follows formula ②: C(i,j)=mod((mod(2M-j-1,N)+i),N), N=3, M=3. For example:

[0056] (1, 4) represents the sub-pixel sp located in the first sub-pixel group Z1 and the fourth second sub-pixel group Z2 in the pixel unit 10. According to formula ②, C(1, 4)=2, that is, the third sub-pixel sp3 is at the position (1, 4).

[0057] (2,5) represents the sub-pixel sp located in the second first sub-pixel group Z1 and the fifth second sub-pixel group Z2 in the pixel unit 10. According to formula ②, C(2,5)=2, that is, the third sub-pixel sp3 is at the position (2,5).

[0058] (1,6) represents the sub-pixel sp located in the first sub-pixel group Z1 and the sixth second sub-pixel group Z2 in the pixel unit 10. According to formula ②, C(1,6)=0, that is, the first sub-pixel sp1 is at the position (1,6).

[0059] The pixel unit 10 obtained according to the sub-pixel sp arrangement rule provided in the embodiment of the present application is as follows Figure 1 As shown, in Figure 1 In the pixel unit 10 shown separately in the figure, the positions (3, 1), (2, 2), (1, 3), (1, 4), (2, 5) and (3, 6) are all third sub-pixels sp3. It can be seen that the third sub-pixels sp3 in the pixel unit 10 are not arranged along the first direction a or the second direction b, but are arranged along an oblique direction intersecting the first direction a and the second direction b, and in a certain regularity. Figure 1 It can be seen that the third sub-pixel sp3 is arranged in a zigzag pattern, with a zigzag having two arms arranged periodically as a unit, and the arm length is 3 (when M=3) sub-pixels. Figure 1 It can also be seen that the first sub-pixel sp1 and the second sub-pixel sp2 are also arranged in a zigzag pattern, and the arrangement rule of the first sub-pixel sp1 and the second sub-pixel sp2 is the same as the arrangement rule of the third sub-pixel sp3.

[0060] In the display panel, a plurality of pixel units 10 are repeatedly arranged. Figure 1 It can be seen that the sub-pixels sp of the three colors are arranged in a zigzag pattern, and the arm length of the zigzag pattern is 3 sub-pixels. That is, the display panel provided in the embodiment of the present application includes sub-pixels sp of N colors, wherein the sub-pixels sp of the same color are arranged in a zigzag pattern, and the arm length of the zigzag pattern is M sub-pixels sp. The display panel provided in the embodiment of the present application can be stacked with a spectroscopic device and applied to naked-eye 3D products.

[0061] Figure 2 A schematic diagram of a display module provided in an embodiment of the present application is shown in FIG. Figure 3 for Figure 2A schematic cross-sectional view at the midline AA′. Figure 2 and Figure 3 From the perspective of the display module, the display module includes a stacked display panel 01 and a light splitting device 02, and the light splitting device 02 includes a cylindrical lens as an example. In the present application, the light splitting device 02 includes but is not limited to cylindrical lenses, micro lenses, barrier gratings, a combination structure of cylindrical lenses and barrier gratings, liquid crystal lenses, liquid crystal gratings, a combination structure of liquid crystal lenses and liquid crystal gratings, and diffusers, etc., which are optical devices that can achieve light splitting. Figure 3 The display panel 01 is only simplified in the figure, and the sub-pixels sp in the display panel 01 are not shown. The display panel 01 can be a liquid crystal display panel, an organic light emitting display panel, or an LED (light-emitting diode) display panel.

[0062] Figure 2 The arrangement of sub-pixels sp in the display panel 01 is similar to Figure 1 The sub-pixels sp in the display panel provided by the embodiment are arranged in the same manner. Figure 2 The shape of the sub-pixel sp is rectangular, and the shape of the light-emitting area of ​​the sub-pixel sp is also rectangular. When the display panel 01 is a liquid crystal display panel, the display panel 01 includes a black matrix, the black matrix has an opening, and one sub-pixel sp includes an opening, and the opening is the light-emitting area of ​​the sub-pixel sp. When the display panel 01 is an organic light-emitting display panel, the opening area of ​​the pixel definition layer in the display panel 01 is the light-emitting area of ​​the sub-pixel sp.

[0063] Figure 2 The optical axis F of the cylindrical lens is schematically shown, and the extending direction of the optical axis F of the cylindrical lens is the bonding direction of the light splitting device 02. Figure 2 It is indicated that the bonding direction of the spectrometer 02 is the same as the extension direction of the long side of the sub-pixel sp. In other words, the bonding direction of the spectrometer 02 is the same as the extension direction of the long side of the light-emitting area of ​​the sub-pixel sp. It can also be said that the light-emitting area includes a first edge, the first edge extends along a first direction a, and the extension direction of the first edge is the same as the bonding direction of the spectrometer 02. Since the arrangement of the sub-pixels sp of the same color in the display panel 01 is serrated, the arrangement direction of the sub-pixels sp of the same color is not parallel to the bonding direction of the spectrometer 02. Compared with the prior art, the present application can break the interference effect between the periodic arrangement of the spectrometer 02 and the periodic arrangement of the sub-pixels, thereby eliminating the moiré caused by the interference between the periodic arrangement of the spectrometer and the periodic arrangement of the sub-pixels.

[0064] The display panel provided in the embodiment of the present application includes a pixel unit 10, and the pixel unit 10 includes sub-pixels sp of N colors. The arrangement of N*2M sub-pixels sp in the pixel unit 10 is designed so that the sub-pixels sp of the same color in the display panel are arranged in a zigzag shape. When applied to naked-eye 3D display products, the arrangement direction of the sub-pixels sp of the same color is not parallel to the bonding direction of the spectroscopic device 02, so that the interference effect between the periodic arrangement of the spectroscopic device 02 and the periodic arrangement of the sub-pixels can be broken, thereby weakening or even eliminating the moiré caused by the interference between the periodic arrangement of the spectroscopic device and the periodic arrangement of the sub-pixels, thereby improving the depth of field of the naked-eye 3D display and enhancing the viewing experience.

[0065] In such Figure 2 In the illustrated display module, at least one side of the light-emitting area of ​​the sub-pixel sp is extended in the same direction as the bonding direction of the light splitter 02, which can prevent the mixing of other viewpoint sub-pixels sp into the sampling line of the light splitter 02, thereby increasing the overlapping area between adjacent viewpoints and causing crosstalk between viewpoints. Figure 2 The solution of the embodiment can reduce the crosstalk between viewpoints of 3D display while reducing the moiré pattern.

[0066] Figure 2 The direction in which the long side of the light-emitting region of the sub-pixel sp extends is the same as the direction in which the light-splitting device 02 is attached. In another embodiment, Figure 4 Another display module schematic diagram provided in the embodiment of the present application is as follows: Figure 4 As shown, the display panel ( Figure 4 The arrangement of sub-pixels sp in (not shown) is similar to Figure 1 The arrangement of the sub-pixels is the same. The spectroscopic device 02 includes a cylindrical lens, and the optical axis F of the cylindrical lens extends along the second direction b, that is, the bonding direction of the spectroscopic device 02 is the second direction b. The bonding direction of the spectroscopic device 02 is the same as the extension direction of the short side of the light-emitting area of ​​the sub-pixel sp. In other words, the short side of the light-emitting area is the first side, the first side extends along the second direction b, and the extension direction of the first side is the same as the bonding direction of the spectroscopic device 02.

[0067] The spectrometer 02 has a certain fitting angle relative to the display panel 01, and the fitting angle range is 0° to ±90°. The fitting angle is explained by taking a rectangular display panel as an example. For example, in conventional applications, the short side direction of the rectangular display panel is horizontal and the long side direction is vertical. When the fitting direction of the spectrometer 02 is parallel to the long side direction, the spectrometer can be considered to be vertically fitted and the fitting angle is 0°. When the fitting direction of the spectrometer 02 has a non-zero angle with both the long side direction and the short side direction, the spectrometer 02 is tilted and fitted, and the fitting angle is not 0°. The specific fitting angle during application is determined according to the specific application scenario.

[0068] Figure 2 In the embodiment, the spectroscopic device 02 is only used as a lens for illustration, and the pitch, radius of curvature, and refractive index of the lens can be any value without special restrictions. In other embodiments, the spectroscopic device 02 is a grating, and the extension direction of the slit of the grating is the bonding direction of the spectroscopic device 02.

[0069] Figure 2 In the embodiment, the angle between at least one side of the light-emitting area of ​​the sub-pixel sp and the bonding direction of the light-splitting device 02 is 0° for illustration. In the embodiment of the present application, the angle α between at least one side of the light-emitting area of ​​the sub-pixel sp and the bonding direction of the light-splitting device 02 is 0°≤α≤5°, that is, there can be a smaller angle between the bonding direction of the light-splitting device 02 and an edge of the light-emitting area of ​​the sub-pixel sp. In practice, the method of rotating the light-splitting device 02 can be used to determine the optimal angle α to ensure the best effect of reducing the influence of moiré. The side of the light-emitting area with an angle α between the bonding direction of the light-splitting device 02 is the first side, and the first side can extend along the first direction a, or the first side extends along the second direction b.

[0070] In some other embodiments, the sub-pixel sp is in a triangular shape. Figure 5 A schematic diagram of another display panel provided in an embodiment of the present application, Figure 5 Take N=3 and M=3 as an example. Figure 5 As shown, the sub-pixel sp is in a triangular shape, one side of the light emitting region of the sub-pixel sp extends along a first direction a, and a second direction b is substantially perpendicular to the first direction a. Figure 5 The dotted lines that intersect horizontally and vertically divide a plurality of pixel units 10. The pixel unit 10 includes 3*6 sub-pixels sp. The arrangement rules of the sub-pixels sp in the pixel unit 10 satisfy the above formulas ① and ②. When the display panel provided in this embodiment is used in a 3D display product, the bonding direction of the spectrometer 02 can be set to the first direction a, that is, the bonding direction of the spectrometer 02 is the same as the extension direction of one side of the light-emitting area of ​​the sub-pixel sp, so as to avoid mixing other viewpoint sub-pixels sp into the sampling line of the spectrometer 02, resulting in an increase in the overlapping area between adjacent viewpoints and causing crosstalk between viewpoints. That is, while reducing the moiré pattern, the crosstalk between viewpoints of the 3D display can also be reduced.

[0071] Figure 5 In the embodiment, one side of the triangular sub-pixel sp light-emitting area extends along the first direction a for illustration. In other embodiments, the sub-pixel sp light-emitting area is triangular, and one side of the light-emitting area extends along the second direction b, which is not illustrated here. When applied in a 3D display product, the bonding direction of the light-splitting device 02 can be set to the second direction b, so that the bonding direction of the light-splitting device 02 is the same as the extension direction of one side of the sub-pixel sp light-emitting area.

[0072] In other embodiments, the sub-pixel sp in the display panel is a square, the square includes two first sides and two second sides, the first side and the second side are perpendicular to each other, the first side extends along the first direction a, and the second side extends along the second direction b, which is not illustrated in the drawings here.

[0073] In some other implementations, taking N=3 and M=4 as an example, Figure 6 A schematic diagram of another display panel provided in an embodiment of the present application, Figure 6 Only a plurality of sub-pixels at local positions within the display area are shown schematically. Figure 6 As shown, the area where the plurality of pixel units 10 are located is divided by the dotted lines that cross horizontally and vertically. The pixel unit 10 includes 3*8 sub-pixels sp, and the pixel unit 10 includes three color sub-pixels sp, namely, the first sub-pixel sp1, the second sub-pixel sp2 and the third sub-pixel sp3, which have different colors. The pixel unit 10 includes 3 first sub-pixel groups Z1 extending along the first direction a and 8 second sub-pixel groups Z2 extending along the second direction b, and the first direction a and the second direction b intersect each other. In the pixel unit 10, the first second sub-pixel group Z2, the second second sub-pixel group Z2, to the eighth second sub-pixel group Z2 are counted from top to bottom, and the first first sub-pixel group Z1, the second first sub-pixel group Z1 and the third first sub-pixel group Z1 are counted from left to right.

[0074] According to the sub-pixel sp arrangement rule in the pixel unit 10 given in the present application, C(i, j) = 0, 1, 2, representing the three colors of the sub-pixel sp, wherein C(i, j) = 0 represents the color of the first sub-pixel sp1, C(i, j) = 1 represents the color of the second sub-pixel sp2, and C(i, j) = 2 represents the color of the third sub-pixel sp3. In the pixel unit 10, the arrangement of the sub-pixels sp in the first to fourth second sub-pixel groups Z2 follows the formula ①: C(i, j) = mod((mod(j-1, N) + i-1), N), and the arrangement of the sub-pixels sp in the fifth to eighth second sub-pixel groups Z2 follows the formula ②: C(i, j) = mod((mod(2M-j-1, N) + i), N), N = 3, M = 4.

[0075] The application of the above formulas ① and ② is explained by taking the arrangement position of the third sub-pixel sp3 in the pixel unit 10 as an example.

[0076] (3, 1) represents the sub-pixel sp located in the third first sub-pixel group Z1 and the first second sub-pixel group Z2 in the pixel unit 10. According to formula ①, C(3, 1)=2, that is, the third sub-pixel sp3 is at the position (3, 1).

[0077] (3, 4) represents the sub-pixel sp located in the third first sub-pixel group Z1 and the fourth second sub-pixel group Z2 in the pixel unit 10. According to formula ①, C(3, 4)=2, that is, the third sub-pixel sp3 is at the position (3, 4).

[0078] (3, 5) represents the sub-pixel sp located in the third first sub-pixel group Z1 and the fifth second sub-pixel group Z2 in the pixel unit 10. According to formula ②, C(3, 5)=2, that is, the third sub-pixel sp3 is at the position (3, 5).

[0079] (1,6) represents the sub-pixel sp located in the first sub-pixel group Z1 and the sixth second sub-pixel group Z2 in the pixel unit 10. According to formula ②, C(1,6)=2, that is, the third sub-pixel sp3 is at the position (1,6).

[0080] Combination Figure 6 Come and see, Figure 6 In the pixel unit 10 shown separately in the figure, the positions (3, 1), (2, 2), (1, 3), (3, 4), (3, 5), (1, 6), (2, 7) and (3, 8) are all third sub-pixels sp3. The positions of the first sub-pixel sp1 and the second sub-pixel sp2 can also be determined according to the arrangement rule formulas ① and ② of the sub-pixels sp, which are not listed here one by one. Figure 6 It can be seen that the third sub-pixel sp3 in the display panel is not arranged along the first direction a or the second direction b, and the third sub-pixel sp3 is arranged in a zigzag shape, and the zigzag of the third sub-pixel sp3 has two arms, and the arm length is 4 (when M=4) sub-pixels. It can also be seen that the first sub-pixel sp1 and the second sub-pixel sp2 are arranged in a zigzag shape. That is, when N=3 and M=4, the sub-pixels sp of the three colors are arranged in a zigzag shape, and the arm length of the zigzag arrangement is 4 sub-pixels.

[0081] In some other implementations, taking N=4 and M=3 as an example, Figure 7 A schematic diagram of another display panel provided in an embodiment of the present application, Figure 7 Only a plurality of sub-pixels at local positions within the display area are shown schematically. Figure 7 As shown, the area where the plurality of pixel units 10 are located is divided by the dotted lines crossing horizontally and vertically. The pixel unit 10 includes 4*6 sub-pixels sp, and the pixel unit 10 includes four color sub-pixels sp, namely, a first sub-pixel sp1, a second sub-pixel sp2, a third sub-pixel sp3 and a fourth sub-pixel sp4, which have different colors. Optionally, the four color sub-pixels sp are respectively one of red, green, blue and white. The pixel unit 10 includes four first sub-pixel groups Z1 extending along a first direction a and six second sub-pixel groups Z2 extending along a second direction b, and the first direction a and the second direction b intersect each other.

[0082] Figure 7 In the embodiment, the sub-pixels sp in the pixel unit 10 meet the sub-pixel sp arrangement rule proposed in the embodiment of the present application: C(i, j) = 0, 1, 2, 3, representing the 4 colors of the sub-pixel sp, wherein C(i, j) = 0 represents the color of the first sub-pixel sp1, C(i, j) = 1 represents the color of the second sub-pixel sp2, C(i, j) = 2 represents the color of the third sub-pixel sp3, and C(i, j) = 3 represents the color of the fourth sub-pixel sp4. In the pixel unit 10, the arrangement of the sub-pixels sp in the first to third second sub-pixel groups Z2 follows the formula ①: C(i, j) = mod((mod(j-1, N) + i-1), N), and the arrangement of the sub-pixels sp in the fourth to sixth second sub-pixel groups Z2 follows the formula ②: C(i, j) = mod((mod(2M-j-1, N) + i), N), N = 4, M = 3. Figure 7 In the embodiment, the sub-pixels sp of the four colors are arranged in a zigzag pattern, and the arm length of the zigzag pattern is 3 sub-pixels.

[0083] In some embodiments, adjacent sub-pixels sp in the pixel unit 10 are misaligned in the first direction a or the second direction b.

[0084] Take N=3, M=3 as an example, Figure 8 A schematic diagram of another display panel provided in an embodiment of the present application, Figure 8 Only one pixel unit 10 is shown in FIG. Figure 8 As shown, the sub-pixel sp is in a rectangular shape, the long side of the sub-pixel sp extends along the first direction a, and the short side of the sub-pixel sp extends along the second direction b. The pixel unit 10 includes three first sub-pixel groups Z1 extending along the first direction a and six second sub-pixel groups Z2 extending along the second direction b. The sub-pixels sp in the first sub-pixel group Z1 are arranged in a staggered manner along the first direction a. Figure 8 The sub-pixel sp shown in the figure is the light-emitting area of ​​the sub-pixel sp, and the spacing between two adjacent light-emitting areas along the second direction b is d2. The sub-pixels sp in the first sub-pixel group Z1 are arranged in a staggered manner along the first direction a, that is, there is a stagger between two adjacent light-emitting areas along the first direction a, wherein the length of the staggered distance between the two adjacent light-emitting areas along the second direction b is l2, and l2≤d2. When the display panel provided by this embodiment is applied to a naked-eye 3D display product, it can further break the interference effect between the periodic arrangement of the light-splitting device 02 and the periodic arrangement of the sub-pixels, thereby further eliminating the moiré caused by the periodic arrangement of the light-splitting device and the periodic arrangement of the sub-pixels, thereby improving the depth of field of the naked-eye 3D display and enhancing the viewing experience.

[0085] Take N=3, M=3 as an example, Fig. 9A schematic diagram of another display panel provided in an embodiment of the present application, Fig. 9 Only one pixel unit 10 is shown in FIG. Fig. 9 As shown, the sub-pixel sp is in a rectangular shape, the long side of the sub-pixel sp extends along the first direction a, and the short side of the sub-pixel sp extends along the second direction b. The pixel unit 10 includes three first sub-pixel groups Z1 extending along the first direction a and six second sub-pixel groups Z2 extending along the second direction b. The sub-pixels sp in the second sub-pixel group Z2 are arranged in a staggered manner along the second direction b. Fig. 9 The sub-pixel sp shown in the figure is the light-emitting area of ​​the sub-pixel sp, for example, the spacing between two adjacent light-emitting areas along the first direction a is d1. The sub-pixels sp in the second sub-pixel group Z2 are arranged in a staggered manner along the second direction b, that is, there is a stagger between two adjacent light-emitting areas along the second direction b, wherein the length of the staggered distance between the two adjacent light-emitting areas along the first direction a is l1, l1≤d1. When the display panel provided by this embodiment is applied to a naked-eye 3D display product, it can further break the interference effect between the periodic arrangement of the light-splitting device 02 and the periodic arrangement of the sub-pixels, thereby further eliminating the moiré caused by the interference between the periodic arrangement of the light-splitting device and the periodic arrangement of the sub-pixels, thereby improving the depth of field of the naked-eye 3D display and enhancing the viewing experience.

[0086] In the above embodiments, the first direction a and the second direction b are perpendicular to each other. In other embodiments, the first direction a and the second direction b have an acute angle. Taking N=3 and M=3 as an example, Fig.10 Another display panel schematic diagram provided in the embodiment of the present application is as follows: Fig.10 As shown, there is an acute angle β between the first direction a and the second direction b. The shape of the sub-pixel sp is a rectangle, wherein the long side of the sub-pixel sp extends along the first direction a, the short side of the sub-pixel sp is perpendicular to the first direction a, and there is a non-zero angle between the short side of the sub-pixel sp and the second direction b, that is, one side of the light-emitting area of ​​the sub-pixel sp is parallel to the first direction a. The sub-pixel sp in the pixel unit 10 satisfies the above-mentioned sub-pixel arrangement rule proposed in the present application. Taking the display panel as a rectangular display panel as an example, when the long side of the rectangular display panel is Fig.10 The horizontal extension of the middle paper and the short edge Fig.10 When extending in the vertical direction of the paper, the pixel unit 10 is equivalent to being inclined relative to the edge of the rectangular display panel. In other words, there is a non-zero angle between the extending direction of the pixel unit 10 and the edge of the rectangular display panel. The display panel provided in this embodiment can be used in 3D display products.

[0087] Fig.11 A simplified schematic diagram of another display module provided by an embodiment of the present invention, Fig.11 The display module includes Fig.10The display panel provided in the embodiment. Fig.11 As shown, the display module includes a stacked display panel 01 and a light splitting device 02. Optionally, the display panel 01 is a rectangular display panel, and the display panel 01 includes a first edge 011 extending along a third direction c and a second edge 012 extending along a fourth direction d, and the third direction c and the fourth direction d are perpendicular to each other. The length of the first edge 011 is less than the length of the second edge 012. Fig.11 The display module provided in the embodiment has a horizontal display mode and a vertical display mode. When the user uses it, the second edge 012 is parallel to the horizontal direction in the horizontal display mode, and the first edge 011 is parallel to the horizontal direction in the vertical display mode.

[0088] The angle between the first direction a and the third direction c is not zero, and the second direction b is parallel to the fourth direction d, that is, the first direction a is not parallel to the third direction c. Taking the beam splitter 02 as a cylindrical lens as an example, Fig.11 , the optical axis F of the cylindrical lens is schematically shown. It can be seen that the extension direction of the optical axis F is approximately the first direction a, and the extension direction of the optical axis F is also the bonding direction of the spectrometer 02. Fig.11 In the embodiment, the sub-pixel sp is rectangular in shape, and the shape of the sub-pixel sp is the same as the shape of its light-emitting area. In this embodiment, the long side extension direction of the light-emitting area of ​​the sub-pixel sp is the same as the bonding direction of the light-splitting device 02, that is, the extension direction of at least one side of the light-emitting area of ​​the sub-pixel sp is the same as the bonding direction of the light-splitting device 02. Fig.11 In the embodiment, the arrangement of the pixel unit 10 makes the arrangement direction of the sub-pixels sp of the same color non-parallel to the bonding direction of the spectroscopic device 02, so that the interference effect between the periodic arrangement of the spectroscopic device 02 and the periodic arrangement of the sub-pixels can be broken, thereby reducing or even eliminating the moiré caused by the periodic arrangement of the spectroscopic device and the periodic arrangement of the sub-pixels, improving the depth of field of the naked eye 3D display and enhancing the viewing experience. Moreover, the extension direction of at least one side of the light-emitting area of ​​the sub-pixel sp is the same as the bonding direction of the spectroscopic device 02, which can avoid the mixing of other viewpoint sub-pixels sp in the sampling line of the spectroscopic device 02 and increase the overlapping area between adjacent viewpoints, so that the crosstalk between viewpoints can be reduced. In addition, the extension direction of the pixel unit 10 is inclined relative to the edge of the display panel 01, which can balance the horizontal screen display effect and the vertical screen display effect of the 3D display, reduce the crosstalk of horizontal screen viewing and vertical screen viewing, and have a large depth of field and high stereoscopic 3D display effect in both horizontal screen mode and vertical screen mode.

[0089] In addition, combined Figure 8 and Fig. 9 The description in Fig.10 In the embodiment, the pixel unit 10 is understood. Fig.10The pixel unit 10 includes a first sub-pixel group Z1 extending along a first direction a and a second sub-pixel group Z2 extending along a second direction b, and an acute angle β is formed between the first direction a and the second direction b. The long side of the sub-pixel sp light-emitting area extends along the first direction a, and the short side of the sub-pixel sp light-emitting area is not parallel to the second direction b. The short side of the sub-pixel sp light-emitting area extends along a fifth direction e, and the fifth direction e is perpendicular to the first direction a. Fig.10 It can be seen that there is a misalignment between two adjacent sub-pixels sp along the fifth direction e, and the misalignment distance between the two is less than or equal to d3, where d3 is the distance between the light-emitting areas of two adjacent sub-pixels sp along the first direction a. In this embodiment, the arrangement of the sub-pixels sp in the pixel unit 10 can ensure that the second direction b is the same as the extension direction of at least one side of the display panel. Fig.11 The second direction b is shown to be the same as the extension direction of the long side of the display panel. This is beneficial for periodically arranging the pixel units 10 to adapt to the shape of the display panel. In some embodiments, the acute angle β between the first direction a and the second direction b is 45°, which can be used in 3D display products to ensure that the angle between the fitting direction of the light splitting device and the horizontal direction is the same in the horizontal display mode and the vertical display mode. In this way, a balance can be achieved between the horizontal display effect and the vertical display effect, reducing the crosstalk between horizontal and vertical viewing, so that both the horizontal mode and the vertical mode have a 3D display effect with a large depth of field and a high degree of stereo. Fig.11 In the embodiment, the first direction a and the second direction b have an acute angle, the second direction b is parallel to the long side of the display panel, and the first direction a is not parallel to the short side of the display panel. In other embodiments, the arrangement of the sub-pixels sp in the pixel unit 10 of the display panel is similar to Fig.11 The arrangement of neutron pixels sp is the same as Fig.11 The difference between the embodiments is that the first direction a is parallel to the long side of the display panel, and the second direction b is not parallel to the short side of the display panel, which is not illustrated in the drawings here.

[0090] In another embodiment, Fig.12 Another display panel schematic diagram provided in the embodiment of the present application is still illustrated with N=3 and M=3. Fig.12As shown, the display panel includes a first edge 011 extending along a third direction c and a second edge 012 extending along a fourth direction d, and the third direction c and the fourth direction d are perpendicular to each other. The length of the first edge 011 is less than the length of the second edge 012. When the user uses it, the second edge 012 is parallel to the horizontal direction in a horizontal screen display mode, and the first edge 011 is parallel to the horizontal direction in a vertical screen display mode. The display panel includes a plurality of pixel units 10, and the pixel unit 10 includes a first sub-pixel group Z1 extending along a first direction a and a second sub-pixel group Z2 extending along a second direction b. The first direction a and the second direction b intersect each other, wherein the first direction a has a non-zero angle with the third direction c and the fourth direction d, and the second direction b has a non-zero angle with the third direction c and the fourth direction d. Optionally, the acute angles formed by the first direction a and the third direction c and the fourth direction d are 45°, and the acute angles formed by the second direction b and the third direction c and the fourth direction d are 45°. Fig.12 The display panel provided in the embodiment can also be applied to 3D display products. For example, when assembling the display module, the bonding direction of the splitter device is set to be approximately the first direction a. In this way, a balance can be achieved between the horizontal screen display effect and the vertical screen display effect, and the crosstalk between horizontal screen viewing and vertical screen viewing can be reduced, so that the 3D display effect with large depth of field and high stereoscopic degree can be achieved in both horizontal screen mode and vertical screen mode.

[0091] Some of the above embodiments are illustrated by using the display panel as a rectangular display panel. In other embodiments, the display panel provided in the embodiments of the present application may also be a circular, elliptical or other special-shaped display panel. The first direction a and the second direction b of the arrangement of the sub-pixels sp in the pixel unit are designed in combination with the application scenario of the display panel. This can break the interference effect between the periodic arrangement of the spectrometer 02 and the periodic arrangement of the sub-pixels, thereby weakening or even eliminating the moiré caused by the periodic arrangement of the spectrometer and the periodic arrangement of the sub-pixels, thereby increasing the depth of field of the naked-eye 3D display and improving the viewing experience. When the display panel has two display modes, the two display modes require the display panel to be rotated 90 degrees to switch. For example, if the two display modes are horizontal and vertical display modes, you can refer to Fig.11 and Fig.12 The pixel unit 10 is designed to balance the display effects in the two display modes and reduce crosstalk, so that both display modes have a 3D display effect with a large depth of field and high stereoscopic degree.
