[0123] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Furthermore, the embodiments and features in the embodiments of this disclosure can be combined with each other without conflict. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0124] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as “comprising” or “including” mean that an element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as “connected” or “linked” are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect.

[0125] It should be noted that the dimensions and shapes of the figures in the accompanying drawings do not reflect actual proportions and are intended only to illustrate the content of this disclosure. Furthermore, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0126] This disclosure provides a display device, as shown in Figures 1 to 6, the display device comprising:

[0127] Display panel 1 includes a display area AA and a peripheral area NA surrounding the display area AA; display panel 1 includes: a plurality of pixel strips 2 extending along a first direction a1 and arranged along a second direction a2, and a plurality of light-shielding portions 3; the first direction a1 and the second direction a2 intersect, and the pixel strips 2 include a plurality of sub-pixels 201 arranged along the first direction a1; the orthographic projection of the plurality of light-shielding portions 3 in the direction perpendicular to the display panel 1 onto the display area AA includes: a plurality of opening areas 9 arranged in an array and at least a light-shielding area 8 located between the opening areas 9; the plurality of light-shielding portions 3 include: a plurality of first light-shielding portions 301 extending along the first direction a1, and a plurality of second light-shielding portions 302 whose extension direction intersects the first direction a1; at least a portion of the first light-shielding portions 301 and the area between adjacent pixel strips 2 overlap in the orthographic projection perpendicular to the display panel 1, and at least a portion of the second light-shielding portions 302 overlap in the orthographic projection perpendicular to the display panel 1 with the orthographic projection of the pixel strips 2 in the direction perpendicular to the display panel 1;

[0128] The beam splitting component 4 is located on the display side of the display panel 1. The beam splitting component 4 includes a plurality of beam splitting structures 401 extending along a third direction a3 and arranged along a fourth direction a4. The third direction a3 intersects with the fourth direction a4. The angle θ1 between the third direction a3 and the normal 6 direction of the first direction a1 is greater than or equal to 0° and less than or equal to 90°.

[0129] The display device provided in this disclosure has at least a portion of the first light-shielding portion overlapping the area between adjacent pixel bars in a direction perpendicular to the display panel. This allows the first light-shielding portion to block the area between adjacent pixel bars, preventing interference between pixel bars of different colors. At least a portion of the plurality of second light-shielding portions overlaps with the orthographic projection of the pixel bars in a direction perpendicular to the display panel in a direction perpendicular to the display panel. This disrupts the periodic arrangement of sub-pixels in the pixel bars, which helps to alleviate moiré patterns.

[0130] In some embodiments, as shown in Figures 5 and 6, the total number of opening areas 9 included in the plurality of light-shielding portions 3 is less than the total number of sub-pixels 201 included in all pixel strips 2.

[0131] The display device provided in this embodiment can alleviate moiré patterns while avoiding excessive impact of the light-shielding portion on the aperture ratio, since the number of multiple opening areas is less than the number of sub-pixels in multiple pixel bars, that is, the number of second light-shielding portions is less than the number of sub-pixels included in the pixel bars.

[0132] It should be noted that Figure 6 is an enlarged schematic diagram of region B1 in Figure 5. Figures 2, 4 to 6 illustrate this with the example of the first direction a1 being perpendicular to the second direction a2. The normal direction 6 of the first direction a1 is the second direction a2.

[0133] It should be noted that the included angles appearing in the embodiments of this disclosure are the same as the mathematical definition of included angles, that is, the smaller angle between intersecting straight lines.

[0134] It should be noted that the pattern of the second light-shielding part and the first light-shielding part projected in the direction perpendicular to the display panel divides the display area into multiple opening areas and light-shielding areas arranged in an array.

[0135] In some embodiments, as shown in FIG2, the area between the opening area 9 at the edge of the display area AA and the peripheral area NA is also a light-shielding area 8; the light-shielding area 8 is divided into: a plurality of first light-shielding areas 801 and a plurality of second light-shielding areas 802; the first light-shielding areas 801 extend along a first direction a1, and the second light-shielding areas 802 extend along a direction intersecting the first direction a1; the light-shielding area 8 between two adjacent opening areas 9 in the first direction a1 is the second light-shielding area 802, and the light-shielding area 8 between two adjacent opening areas 9 in the second direction a2 is the first light-shielding area 801. The first light-shielding area 801 corresponds to the area of ​​the first light-shielding part 301 projected in a direction perpendicular to the display panel 1, and the second light-shielding area 802 corresponds to the area of ​​the second light-shielding part 302 projected in a direction perpendicular to the display panel 1.

[0136] In some embodiments, the display panel further includes: bonding pins that are electrically connected to the multiple signal lines;

[0137] As shown in Figure 4, the portion of the signal line 10 located in the display area (not shown) falls into the light-shielding area 8 in the orthographic projection perpendicular to the direction of the display panel 1.

[0138] The display device provided in this disclosure has a smaller number of opening areas than the number of sub-pixels. At least in one direction, the number of opening areas corresponding to a pixel strip is less than the number of sub-pixels included in the pixel strip. Since the signal lines are located in the light-shielding area, the number of signal lines corresponding to a pixel strip is less than the number of sub-pixels included in the pixel strip in at least one direction, thus reducing the number of signal lines. Signal lines typically need to be electrically connected to bonding pins, which also reduces the number of bonding pins, saving costs and simplifying wiring.

[0139] In some embodiments, the display device further includes a driver chip bonded to bonding pins. In specific implementations, the display panel may be bonded to one or more driver chips. When the display panel needs to be bonded to multiple driver chips, reducing the number of bonding pins can also reduce the number of driver chips, thus saving costs.

[0140] In some embodiments, as shown in FIG5, the plurality of pixel strips 2 include a plurality of pixel strips 2 with different light emission colors; the plurality of pixel strips 2 are divided into a plurality of repeating units 16; the repeating unit 16 includes a plurality of pixel strips 2 with different light emission colors; one repeating unit 16 includes a plurality of pixel islands S; in the pixel islands S, a plurality of sub-pixels 201 are included in the first direction a1.

[0141] It should be noted that the display device provided in this disclosure can be applied to three-dimensional (3D) display and can also switch between 3D and two-dimensional (2D) display. A pixel island can serve as a pixel in a 2D display. Since a pixel island includes multiple sub-pixels arranged in an array, it can maintain the same resolution as the 2D display in 3D display mode. Combined with an eye-tracking system, it can achieve multi-view display with a wide field of view, and can also achieve 3D display with higher pixel density (ppi), more information, and lower color crosstalk between adjacent viewpoints.

[0142] In some embodiments, when the display mode of the display device is 3D display mode, the sub-pixels in the pixel bar emit light continuously through the light emitted by the beam splitter.

[0143] Specifically, because the size of the beam-splitting structure in its arrangement direction is small, the human eye cannot distinguish which beam-splitting structure the light is emitted from. The light emitted by the sub-pixels in the pixel bar after passing through the beam-splitting component is continuously emitted, so the human eye will not see "black areas" when moving in the visible space, which can eliminate moiré patterns and improve the display effect.

[0144] In some embodiments, the display panel includes PX1 repeating units, each repeating unit includes PX2 pixel islands, and each pixel strip includes PX2×PX3 subpixels; then the resolution of the 3D display is PX1×PX2×PX3, and the resolution of the 2D display is PX1×PX2.

[0145] In some embodiments, as shown in FIG5, the plurality of pixel bars 2 include a plurality of first pixel bars 2-1, a plurality of second pixel bars 2-2, and a plurality of third pixel bars 2-3; the plurality of pixel bars 2 are periodically arranged with the first pixel bars 2-1, the second pixel bars 2-2, and the third pixel bars 2-3 forming a repeating unit 16;

[0146] The first pixel bar 2-1 includes multiple first sub-pixels 201-1, the second pixel bar 2-2 includes multiple second sub-pixels 201-2, and the third pixel bar 2-3 includes multiple third sub-pixels 201-3.

[0147] For example, the first sub-pixel is a red sub-pixel, the second sub-pixel is a green sub-pixel, and the third sub-pixel is a green sub-pixel.

[0148] In practical implementation, the beam-splitting component is a one-dimensional light-controlling device. The beam-splitting structure has one-dimensional directional light-controlling capability, controlling the emission angle of each sub-pixel to make it emit light in a directional manner. Specifically, the beam-splitting structure does not control light in the third direction, but has light-controlling capability in the fourth direction.

[0149] In some embodiments, the beam-splitting component includes one of a cylindrical lens array, a liquid crystal cylindrical lens array, a parallax barrier, and a liquid crystal dynamic parallax barrier.

[0150] In some embodiments, when the beam splitting assembly includes a cylindrical lens array, as shown in FIG1, the beam splitting structure 401 is a cylindrical lens 4011. As shown in FIG1, the beam splitting assembly 4 includes a first resin layer 402 with protrusions and a planarization resin layer 403 located on the side of the first resin layer 402 facing away from the display panel 1; the refractive index of the planarization resin layer 403 is less than the refractive index of the first resin layer 402.

[0151] In some embodiments, when the beam-splitting component includes a liquid crystal cylindrical lens array, specifically, the beam-splitting component is a liquid crystal cell, the liquid crystal cell is driven to form a liquid crystal cylindrical lens array, and the beam-splitting structure is the formed liquid crystal cylindrical lens.

[0152] In some embodiments, as shown in FIG1, the display device further includes:

[0153] The spacer medium layer 13 is located between the beam splitter 4 and the display panel 1.

[0154] In some embodiments, as shown in FIG3, the display panel 1 is a liquid crystal display panel. The display panel 1, i.e., the liquid crystal display panel, includes:

[0155] As shown in FIG4, the array substrate 101 includes a plurality of pixel strips 2 and a plurality of signal lines 10;

[0156] The opposing substrate 102 is disposed opposite to the array substrate 101; the opposing substrate includes a light-shielding layer 20, and the light-shielding layer 20 includes a first light-shielding portion 301.

[0157] The first liquid crystal layer 103 is located between the array substrate 101 and the opposing substrate 102.

[0158] In some embodiments, the opposing substrate is located on the side of the array substrate facing the beam splitter.

[0159] In some embodiments, as shown in FIG3, sub-pixel 201 includes: pixel electrode 12.

[0160] In some embodiments, as shown in FIG3, the array substrate 101 further includes: a first substrate 1012, a thin film transistor TFT located between the first substrate 1012 and the pixel electrode 12, the thin film transistor TFT including an active layer 1011, a gate G, a source S and a drain D; the pixel electrode 12 is electrically connected to the drain D of the thin film transistor TFT, and the thin film transistor TFT and the pixel electrode 12 are located on the side of the first substrate 1012 facing the first liquid crystal layer 103;

[0161] The opposing substrate 102 further includes: a second substrate 1021 and a plurality of color resists 1022; the first light-shielding portion 301 and the color resists 1022 are located on the side of the second substrate 1021 facing the liquid crystal layer 103; the orthographic projection of the color resists 1022 on the plane perpendicular to the display panel includes at least the portion located in the opening area 9, and the color resists 1022 includes at least the portion located on the same layer as the first light-shielding portion 301.

[0162] In some embodiments, one pixel bar corresponds to one color resist. Multiple color resists include a first color resist corresponding to a first sub-pixel, a second color resist corresponding to a second sub-pixel, and a third color resist corresponding to a third sub-pixel.

[0163] It should be noted that in related technologies, the opening area of ​​the light-shielding layer is usually the same as the area of ​​the sub-pixel. However, in the display device provided in this disclosure, the number of sub-pixels is less than the number of opening areas of the light-shielding layer, and the area of ​​the sub-pixel is no longer equivalent to the opening area of ​​the light-shielding layer. The area of ​​the sub-pixel corresponds to the area of ​​the pixel electrode, that is, the area of ​​the sub-pixel is the area where the pixel electrode signal drives the liquid crystal in the liquid crystal layer to deflect.

[0164] In some embodiments, as shown in FIG3, the array substrate 101 further includes: a first buffer layer 1013 located between the first substrate 1012 and the active layer 1011; a gate insulating layer 1014 located between the gate G and the active layer 1011; an interlayer insulating layer 1015 located between the gate G and the source S and drain D; and a first insulating layer 1016 located between the pixel electrode 12 and the drain D. It should be noted that FIG3 uses a thin-film transistor (TFT) with a top-gate structure as an example, meaning the gate is located on the side of the active layer 1011 away from the first substrate 1012.

[0165] Of course, in specific implementations, thin-film transistors can also be bottom-gate structures, that is, the active layer is located on the side of the gate away from the first substrate.

[0166] In some embodiments, as shown in FIG3, the array substrate 101 further includes: a light-shielding pattern 1016 and a second buffer layer 1017 located between the light-shielding pattern 1016 and the active layer 1011.

[0167] Specifically, the light-shielding pattern is projected onto the first substrate and covers the channel region of the thin-film transistor.

[0168] In some embodiments, the array substrate 101 may further include a common electrode 1018; FIG3 illustrates this by taking the common electrode 1018 located on the side of the pixel electrode 12 away from the first substrate 1012 as an example. The array substrate 101 may also include a second insulating layer 1019 located between the common electrode 1018 and the pixel electrode 12.

[0169] Of course, in practice, the common electrode can also be located between the pixel electrode and the drain electrode.

[0170] In practice, thin-film transistors, pixel electrodes, and sub-pixels are in a one-to-one correspondence. That is, each sub-pixel corresponds to a set of electrically connected thin-film transistors and pixel electrodes, thus allowing independent control of the display information of each sub-pixel.

[0171] In some embodiments, as shown in FIG4, the plurality of signal lines 10 include: a plurality of first signal lines 1001 and a plurality of second signal lines 1002; at least a portion of the first signal lines 1001 and at least a portion of the second signal lines 1002 are electrically connected to a plurality of pixel strips 2; the plurality of first signal lines 1001 and the plurality of second signal lines 1002 are arranged to cross each other.

[0172] In some embodiments, the first signal line and the second signal line extend to the surrounding area.

[0173] In some embodiments, as shown in FIG4, multiple first signal lines 1001 extend along the horizontal direction X, and multiple second signal lines 1002 extend along the vertical direction Y; the horizontal direction X is perpendicular to the vertical direction Y, and the first direction a1 is either the horizontal direction X or the vertical direction Y.

[0174] It should be noted that the horizontal direction X and vertical direction Y of the display device are fixed horizontal and vertical directions preset from its appearance. These directions do not represent the actual horizontal and vertical directions relative to the user's eyes when viewing the display device, and they do not change with rotation or other operations of the display device. The specific directions X and Y of the display device can be set according to its purpose and shape. For example, when the display panel or display device is rectangular or rounded, and the rectangle or rounded rectangle has a pair of long sides and a pair of short sides, the direction parallel to the long side can be horizontal and the direction parallel to the short side can be vertical, or vice versa. For example, for display devices like mobile phones, the direction parallel to the short side can be set to horizontal, while for display devices like tablets, the direction parallel to the long side can be set to horizontal.

[0175] It should be noted that the multiple first signal lines extending along the horizontal direction X can be either straight lines or non-straight lines, such as zigzag lines, where at least a portion of the first signal lines form an angle greater than 0 with respect to the horizontal direction X. Similarly, the multiple second signal lines extending along the vertical direction Y can be either straight lines or non-straight lines, such as zigzag lines, where at least a portion of the second signal lines form an angle greater than 0 with respect to the vertical direction Y.

[0176] It should be noted that Figure 4 uses the first direction a1 as the vertical direction Y as an example for illustration. The extension direction of the first signal line 1001 is the same as the extension direction of the second light-shielding area 802, and the extension direction of the second signal line 1002 is the same as the extension direction of the first light-shielding area 801. The example is that the orthographic projection of the first signal line 1001 located in the display area (not shown) in the direction perpendicular to the display panel 1 falls into the second light-shielding area 802, and the orthographic projection of the second signal line 1002 located in the display area (not shown) in the direction perpendicular to the display panel 1 falls into the first light-shielding area 801.

[0177] It should be noted that multiple first signal lines extending along the horizontal direction X can be either straight lines or non-straight lines, such as zigzag lines. Similarly, multiple second signal lines extending along the vertical direction Y can be either straight lines or non-straight lines, such as zigzag lines.

[0178] In some embodiments, the first signal line electrically connected to the gate of the thin-film transistor is a scan line, and the second signal line electrically connected to the source of the thin-film transistor is a data line.

[0179] In some embodiments, the light-shielding layer of the opposing substrate further includes a second light-shielding portion. That is, the light-shielding layer includes an opening area.

[0180] Alternatively, in some embodiments, the first signal line or the second signal line is multiplexed as a second light-shielding part. Figures 5 and 6 illustrate this by taking the example of the first signal line 1001 being multiplexed as a second light-shielding part.

[0181] It should be noted that signal lines are typically made of metal, thus providing a light-shielding effect. When the first or second signal line is multiplexed as a second light-shielding component, it serves both signal transmission and light-shielding functions.

[0182] In some embodiments, when the first signal line or the second signal line is multiplexed as a second light-shielding portion, the orthographic projection of the second light-shielding portion in the direction perpendicular to the display panel overlaps with the orthographic projection of the first light-shielding portion in the direction perpendicular to the display panel. In the pattern formed by the interweaving of the orthographic projections of the second light-shielding portion and the first light-shielding portion in the direction perpendicular to the display panel, the blank area (the area without a light-shielding portion) in the display area is an opening area.

[0183] In some embodiments, the first signal line or the second signal line is multiplexed as a second light-shielding portion, located in the light-shielding area between adjacent opening areas in the first direction. The opposing substrate does not include a light-shielding layer, that is, in the portion of the area corresponding to the second light-shielding portion, the opposing substrate does not have a light-shielding layer. In other words, the display panel uses a light-shielding layer in conjunction with the second light-shielding portion to provide light protection.

[0184] Of course, in some embodiments, a light-shielding layer may also be provided on the opposing substrate in the light-shielding area located between adjacent opening areas in the first direction.

[0185] In some embodiments, as shown in Figures 5 and 6, the number of second light-shielding portions 302 is less than the number of sub-pixels 201 included in the pixel strip 2. Specifically, since the region of the pixel electrode corresponds to the region of the sub-pixel, the number of second light-shielding portions 302 is less than the number of pixel electrodes (not shown) included in the pixel strip 2. That is, when the first signal line or the second signal line is multiplexed as a second light-shielding portion, the number of the first signal line or the number of the second signal line is less than the number of sub-pixels and pixel electrodes included in the pixel strip.

[0186] In some embodiments, multiple sub-pixels arranged horizontally form a row of sub-pixels, and multiple sub-pixels arranged vertically form a column of sub-pixels.

[0187] In some embodiments, when the first direction is horizontal, the number of data lines is half the number of sub-pixels included in a pixel bar; one data line corresponds to electrically connecting two columns of sub-pixels.

[0188] In some embodiments, when the first direction is horizontal, the plurality of second signal lines include, in addition to the plurality of data lines, at least one dummy second signal line; the dummy second signal line is not electrically connected to the pixel bar.

[0189] In some embodiments, when the first direction is vertical, the number of scan lines is half the number of sub-pixels included in a pixel bar; a scan line is electrically connected to two adjacent sub-pixels in a pixel bar.

[0190] In some embodiments, as shown in FIG5, when the first direction a1 is the vertical direction Y, the multiple first signal lines 1001 include not only multiple scan lines 10011, but also at least one dummy first signal line 10012; the dummy first signal line 10012 is not electrically connected to the pixel strip 2.

[0191] In some embodiments, the first row of first signal lines and / or the last row of first signal lines in the arrangement direction of multiple first signal lines are dummy first signal lines. Figure 5 illustrates this by taking the first first signal line 1001 (i.e., the topmost first signal line 1001) in the arrangement direction of multiple first signal lines 1001 as an example of a dummy first signal line 10012.

[0192] In some embodiments, as shown in FIG6, sub-pixel 201 includes a pair of first sides 5 whose extension direction intersects the first direction a1.

[0193] In some embodiments, as shown in Figures 5 and 6, the outline shape of the sub-pixel 201 in the direction perpendicular to the display panel 1 is non-rectangular.

[0194] In some embodiments, as shown in Figures 5 and 6, the outline shape of the sub-pixel 201 in the direction perpendicular to the display panel 1 is approximately a parallelogram.

[0195] In some embodiments, as shown in Figures 5 and 6, the sub-pixel 201 further has a pair of sides extending along a first direction a1. The length of the first side 5 is greater than the length of the side of the sub-pixel 201 extending along the first direction a1. That is, the first side 5 is the longer side of the sub-pixel 201.

[0196] In some embodiments, as shown in FIG6, the angle θ2 between the first side 5 and the normal 6 direction of the first direction a1 is greater than 0° and less than 90°, and the angle θ4 between the extension direction of the second light-shielding part 302 and the first side 5 is greater than 0°.

[0197] The orthographic projection of the second light-shielding part 302 in the direction perpendicular to the display panel 1 overlaps with the orthographic projection of the sub-pixel 201 in the direction perpendicular to the display panel 1.

[0198] The display device provided in this embodiment has an angle greater than 0° between the extension direction of the second light-shielding part and the first side, meaning that the extension direction of the second light-shielding part is different from the extension direction of one pair of sides of the sub-pixel, which helps to break the regular arrangement of the sub-pixel area and alleviate moiré patterns.

[0199] In some embodiments, as shown in FIG4, the extending direction of the pixel electrode 12 is the same as the extending direction of the first side (not shown); the orthographic projection of the pixel electrode 12 in the direction perpendicular to the display panel 1 overlaps with the orthographic projection of the second light-shielding portion 302 in the direction perpendicular to the display panel 1, and the opening region 9 overlaps with the orthographic projection of the pixel electrode 12 in the direction perpendicular to the display panel 1.

[0200] In some embodiments, as shown in FIG6, the opening region 9 overlaps with the orthographic projections of the plurality of sub-pixels 2 and the plurality of pixel electrodes (not shown) in the direction perpendicular to the display panel 1; the orthographic projection of the second light-shielding portion 302 in the direction perpendicular to the display panel 1 overlaps with the orthographic projections of the plurality of sub-pixels 2 and the plurality of pixel electrodes (not shown) in the direction perpendicular to the display panel 1.

[0201] The second light-shielding part 302 divides the area of ​​the sub-pixel 2 into multiple parts by projecting its orthographic projection in a direction perpendicular to the display panel 1.

[0202] In some embodiments, any straight line along the third direction a3 passes through the center of the first sub-pixel, the center of the second sub-pixel, and the center of the third sub-pixel. This prevents color separation between different sub-pixels in 3D display mode.

[0203] In some embodiments, as shown in FIG6, the angle θ1 between the third direction a3 and the normal 6 direction of the first direction a1 satisfies:

[0204] Where P1 is the arrangement period of pixel strip 2, P2 is the arrangement period of multiple sub-pixels 201 in pixel strip 2 in the first direction a1, and j is an integer greater than or equal to 0.

[0205] The display device provided in the embodiments of this disclosure This ensures that any straight line along the third direction a3 approximately passes through the center of the first sub-pixel, the center of the second sub-pixel, and the center of the third sub-pixel within a reasonable range of process error, thus preventing color separation between different sub-pixels in 3D display mode.

[0206] In some embodiments, as shown in FIG6 This ensures that any straight line along the third direction a3 passes through the center of the first sub-pixel, the center of the second sub-pixel, and the center of the third sub-pixel, further preventing color separation between different sub-pixels in 3D display mode.

[0207] In some embodiments, the display device shown in FIG. 6 has j = 4. That is, in FIG. 6,

[0208] Of course, in practice, j=1, j=3, etc.

[0209] In some embodiments, as shown in FIG6, when In this case, θ1 = θ2. This can further reduce crosstalk in the displayed view in 3D display mode.

[0210] It should be noted that, This is a setting method from the perspective of avoiding color separation. In actual implementation, if other issues are considered, θ1 and θ2 can also be set in other ways.

[0211] In some embodiments, as shown in FIG7, the total length of the region W1 where the first preset length line segment L1 and the second light-shielding part 302 overlap in the third direction a3 is the first length w1; within a beam splitting structure 401, the first length w1 corresponding to any first preset length line segment L1 is equal.

[0212] The first preset length line segment L1 extends along the third direction a3. The projection length of the first preset length L1 in the direction of the normal 6 of the first direction a1 (the second direction a2 in Figure 7) is the difference between P1 and P4, i.e. (P1-P4). That is, the first preset length L1 is equal to the width of the opening area 9 in the second direction a2. P3 is the arrangement period of the second light-shielding part 302 in the first direction a1; P4 is the width of the first light-shielding part 301 in the direction perpendicular to the first direction a1.

[0213] In some embodiments, as shown in FIG7, the length of the second light-shielding portion 302 on the third direction a3 is a second length w2.

[0214] It should be noted that the number of complete second light-blocking portions 302 passing through any first preset length L1 on the third direction a3 is defined as the integer part of the ratio of the first length w1 to the second length w2. Within a beam splitting structure 401, when the first length w1 corresponding to any first preset length line segment L1 is equal, that is, within a beam splitting structure 401, the number of complete second light-blocking portions 302 passing through any first preset length L1 on the third direction a3 is equal.

[0215] The display device provided in this embodiment has a first length w1 corresponding to any first preset length line segment L1 within a beam-splitting structure. That is, the number of complete second light-shielding parts passing through any first preset length in the third direction is equal, thereby alleviating or even eliminating moiré patterns and improving the display effect.

[0216] In some embodiments, when any first preset length line segment L1 corresponds to the same first length w1, the ratio of the first length w1 to the second length w2 is an integer.

[0217] It should be noted that Figure 7 uses an example where the ratio of the first length w1 to the second length w2 is 1. That is, within a beam splitting structure 401, the number of complete second light-shielding portions 302 passing through any first preset length L1 on the third direction a3 is 1. The first preset length L1 shown in Figure 7 overlaps with only one second light-shielding portion 302, and the first preset length L1 passes through a complete second light-shielding portion 302. However, within a beam splitting structure 401, on the third direction a3, in other unlabeled locations, the first preset length L1 overlaps with two second light-shielding portions 302, but in some locations, the first preset length L1 passes through two incomplete second light-shielding portions 302. However, the first length w1 corresponding to the first preset length L1 is still equal to the second length w2. Therefore, the number of complete second light-shielding portions 302 passing through any first preset length L1 on the third direction a3 is 1.

[0218] In some embodiments, as shown in FIG7, the angle θ1 between the third direction a3 and the normal 6 direction of the first direction a1 satisfies:

[0219] Wherein, P1 is the arrangement period of pixel strip 2; P3 is the arrangement period of second light-shielding part 302 on the first direction a1; P4 is the width of first light-shielding part 301 on the direction perpendicular to the first direction a1; and i is the integer part of the ratio of first length w1 to second length w2.

[0220] The display device provided in the embodiments of this disclosure Thus, within a reasonable range of process error, the number of complete second light-shielding parts passing through any first preset length in the third direction can be equal, thereby alleviating or even eliminating moiré patterns and improving the display effect.

[0221] In some embodiments, as shown in Figure 7

[0222] In some embodiments, in the display device corresponding to FIG7, within a beam-splitting structure 401, the ratio of the first length w1 to the second length w2 is 1, that is, the number of complete second light-shielding portions 302 passing through any first preset length L1 on the third direction a3 is 1, i = 1.

[0223] In some embodiments, the following conditions can be met simultaneously: as well as This can prevent color separation between different sub-pixels in 3D display mode, while also alleviating or even eliminating moiré patterns, further improving the display effect.

[0224] In some embodiments, as shown in Figures 5 to 7, the extension direction of the second light-shielding portion 302 is perpendicular to the first direction a1. In Figures 5 to 7, the first direction a1 is perpendicular to the second direction a2, and the extension direction of the second light-shielding portion 302 is the second direction a2.

[0225] Alternatively, in some embodiments, as shown in FIG8, the angle θ3 between the extension direction of the second light-shielding part 302 and the normal direction 6 of the first direction a1 is greater than 0° and less than 90°.

[0226] It should be noted that when the extension direction of the second light-shielding part is perpendicular to the first direction, and it is impossible to satisfy... In a beam-splitting structure, the first length w1 corresponding to any first preset length line segment L1 is not completely equal. That is, the number of complete second light-shielding portions passing through the first preset length in different regions in the third direction is not completely equal, which poses a risk of moiré patterns. The display device provided in this embodiment, where θ3 is greater than 0° and less than 90° (i.e., the extension direction of the second light-shielding portion is not perpendicular to the first direction a1), can still achieve equal first length w1 corresponding to any first preset length line segment L1 within a beam-splitting structure. This means the number of complete second light-shielding portions passing through the first preset length in any region in the third direction is equal, which helps to alleviate or even eliminate moiré patterns and improve the display effect.

[0227] When not satisfied At that time, that is or In some embodiments, as shown in FIG8, the angle θ1 between the third direction a3 and the normal 6 direction of the first direction a1 satisfies:

[0228] Where P1 is the arrangement period of pixel strip 2; θ3 is the angle between the extension direction of the second light-shielding part 302 and the normal direction 6 of the first direction a1; and i is the rounded ratio of the first length w1 to the second length w2.

[0229] The display device provided in this embodiment has a second light-shielding portion whose extension direction is not perpendicular to the first direction a1, and θ3 and θ1 satisfy the following conditions, taking into account reasonable process errors: This ensures that within a beam-splitting structure, the first length w1 corresponding to any first preset length line segment L1 is equal, meaning that the number of complete second light-shielding parts passing through the first preset length in any region in the third direction is equal. This can further alleviate or even eliminate moiré patterns and improve the display effect.

[0230] In some embodiments,

[0231] In some embodiments, in the display device corresponding to FIG8, within a beam-splitting structure 401, the first length corresponding to any first preset length line segment is 1, that is, the number of complete second light-shielding portions 302 passing through any first preset length L1 on the third direction a3 is 1, i = 1.

[0232] Of course, in specific implementation, when or When the first length w1 corresponding to any first preset length line segment L1 in a beam splitting structure is not completely equal, that is, when the number of complete second light-shielding parts passing through the first preset length in different regions in the third direction is not completely equal, moiré patterns can be alleviated or even eliminated by other means.

[0233] In some embodiments, as shown in Figures 9 to 13, the extension direction of the second light-shielding portion 302 is perpendicular to the first direction a1, and the display panel 1 further includes a plurality of third light-shielding portions 303; the third light-shielding portion 303 includes at least one sub-light-shielding portion 7, and the sub-light-shielding portion 7 includes a first portion 13.

[0234] The orthographic projection of the first part 13 perpendicular to the display panel 1 does not overlap with the orthographic projections of the first light-shielding part 301 and the second light-shielding part 302 perpendicular to the display panel 1, and the orthographic projection of the first part 13 perpendicular to the display panel 1 is adjacent to the orthographic projection of the first light-shielding part 301 or the second light-shielding part 302 perpendicular to the display panel 1.

[0235] When the first length w1 corresponding to any first preset length line segment L1 within a beam splitting structure is not completely equal, in some embodiments, as shown in FIG9, the total length of the area where the first preset length line segment L1 overlaps with the first part 13 of the third light-shielding part 303 in the third direction a3 is the third length (denoted as w3), and w3 is greater than or equal to 0; the total length of all the first parts 13 of the third light-shielding part 303 in the third direction is the fourth length (denoted as w4).

[0236] The ratio of the first length w1 to the second length w2 is rounded up to the first ratio value, and the ratio of the third length w3 to the fourth length w4 is rounded up to the second ratio value;

[0237] Within a beam splitting structure 401, the sum of the first ratio and the second ratio corresponding to any first preset length line segment L1 is equal;

[0238] The first preset length line segment L1 extends along the third direction a3. The projection length of the first preset length L1 in the direction of the normal 6 of the first direction a1 (the second direction a2 in Figure 9) is the difference between P1 and P4 (P1-P4). That is, the first preset length L1 is equal to the width of the opening area 9 in the second direction a2. P3 is the arrangement period of the second light-shielding part 302 in the first direction a1; P4 is the width of the first light-shielding part 301 in the direction perpendicular to the first direction a1.

[0239] It should be noted that within a beam-splitting structure, any first preset length L1 will overlap with the second light-shielding portion. However, at some locations, the first preset length L1 does not overlap with the first portion; in this case, w3 equals 0. The number of complete third light-shielding portions passing through any first preset length L1 on the third direction a3 is defined as the integer part of the ratio of the third length w3 to the fourth length w4. Within a beam-splitting structure, when the sum of the first ratio and the second ratio corresponding to any first preset length line segment L1 is equal, that is, within a beam-splitting structure, the sum of the number of complete third light-shielding portions passing through any first preset length L1 on the third direction a3 is equal to the number of second light-shielding portions.

[0240] The display device provided in this embodiment further includes a third light-shielding part in the display panel. The non-first part of the third light-shielding part is adjacent to the first light-shielding part or the second light-shielding part, so that the opening area is no longer a regular rectangle. Within a beam-splitting structure, the sum of the first ratio and the second ratio corresponding to any first preset length line segment is equal. This can achieve that the sum of the number of third light-shielding parts and second light-shielding parts of the first preset length passing through different areas in a third direction within a beam-splitting structure is equal. This setting can alleviate or even eliminate moiré patterns.

[0241] In some embodiments, when the sum of the first ratio and the second ratio corresponding to any first preset length line segment is equal, the ratio of the first length w1 to the second length w2 is an integer, and the ratio of the third length w3 to the fourth length w4 is an integer.

[0242] In some embodiments, as shown in Figures 9 to 13, the sum S of the orthographic projection areas S of the first portion 13 included in the third light-shielding part 303 in the direction perpendicular to the display panel 1 satisfies:

[0243] in, or P1 is the arrangement period of pixel strip 2; P3 is the arrangement period of second light-shielding part 302 in the first direction a1; P4 is the width of first light-shielding part 301 in the direction perpendicular to the first direction a1; P5 is the width of second light-shielding part 302 in the first direction a1; i is the integer part of the ratio of first length w1 to second length w2, and i' is the sum of the first ratio and the second ratio.

[0244] In some embodiments, This is more conducive to mitigating or even eliminating moiré patterns. However, considering process errors, S satisfies: It can still achieve a good effect of alleviating or even eliminating moiré patterns.

[0245] It should be noted that when the first length w1 corresponding to any first preset length line segment L1 is not exactly equal, the integer value of the ratio of different first length w1 to second length w2 may be the same or different, that is, i can take more than one value. When i can take more than one value, as long as one of the values ​​satisfies or Therefore, it can be assumed that |tanθ1|> or conditions.

[0246] In some embodiments, as shown in Figures 9 and 10, the third light-shielding part 303 includes a plurality of sub-light-shielding parts 7 with equal areas.

[0247] In some embodiments, as shown in Figures 9 to 10, the plurality of sub-shading portions 7 include: a first sub-shading portion 7-1 and a second sub-shading portion 7-2 located on both sides of the second shaded portion 302 in the first direction a1.

[0248] In some embodiments, as shown in FIG9, the first portion 13 of the first sub-shielding portion 7-1 and the second sub-shielding portion 7-2, in a projection perpendicular to the display panel 1, is adjacent to the second sub-shielding portion 302 in a projection perpendicular to the display panel 1.

[0249] In some embodiments, as shown in FIG9, the first sub-shading part 7-1 and the second sub-shading part 7-2 are staggered in the direction of the normal 6 of the first direction a1.

[0250] Therefore, the two sub-shielding parts are not arranged in a regular pattern, which is more conducive to achieving the sum of the first ratio and the second ratio corresponding to any first preset length line segment L1 within a beam splitting structure. That is, the sum of the number of third shielding parts and second shielding parts passing through different regions on the third direction a3 is equal. This setting can further alleviate or even eliminate moiré patterns.

[0251] In some embodiments, as shown in FIG9, the display device is illustrated by taking the sum of the first ratio and the second ratio as 2; the length of the first part 13 in the third direction is w41, and the total length of the two first parts 13 included in the third light-shielding part 303 in the third direction is w41, w4 = 2 × w41; the first preset length L1 shown in FIG9 overlaps with the second light-shielding part 303 and the third light-shielding part 303 in the W2 region, and in the W2 region, w3 = w4 = 2 × w41, w2 = w1; in other unmarked locations, there are also locations where the first preset length L1 and the first part do not overlap. In the overlapping area, w3 equals 0. The first preset length L1 and the two second light-shielding parts 302 have an overlapping area, w2 = 2 × w1. That is, for the display device shown in FIG9, within a beam splitting structure 401, the number of complete second light-shielding parts 302 passing through the first preset length L1 on the third direction a3 is 1 or 2, and the number of complete third light-shielding parts 303 passing through the first preset length L1 on the third direction a3 is 1 or 0. That is, the sum of the number of complete second light-shielding parts 302 and complete third light-shielding parts 303 passing through the first preset length L1 on the third direction a3 is 2, i = 1, 2, i' = 2.

[0252] In some embodiments, as shown in FIG9, in the direction of the normal 6 of the first direction a1, the misalignment distance P9 between the first sub-shading part 7-1 and the second sub-shading part 7-2 satisfies:

[0253] The distance P8 between the first sub-shading part 7-1 or the second sub-shading part 7-2 and the nearest first shading part 301 satisfies: i' is greater than or equal to 2.

[0255] It should be noted that during the display panel manufacturing process, factors such as manufacturing errors may occur, resulting in P9 not being equal to... P8 does not equal Under the condition that, within a reasonable process error range, P8 satisfies: P9 satisfies: It can still alleviate or even eliminate moiré patterns.

[0256] In some embodiments, as shown in FIG9, the first portion 13 of the first sub-shading portion 7-1 and the first portion 13 of the second sub-shading portion 7-2 have the same shape; both are strip-shaped.

[0259] The side length P11 of the first part 13 in the first direction a1 satisfies: i' is greater than or equal to 2.

[0260] When the first sub-shielding part and the second sub-shielding part are located on both sides of the second shielding part in the first direction, and the orthographic projections of the second shielding part are adjacent, the sub-shielding parts meet the above conditions within a reasonable process error range, which can further alleviate or even eliminate moiré patterns, while avoiding affecting the size of the opening area as much as possible.

[0262] In some embodiments, as shown in FIG10, the first portion 13, in its orthographic projection perpendicular to the display panel 1, is adjacent to the first light-shielding portion 301 on both sides of the pixel strip 2 in its orthographic projection perpendicular to the display panel 1.

[0263] In some embodiments, as shown in FIG10, in the direction of the normal 6 of the first direction a1, the distance P12 between the two sides of the first sub-shading part 7-1 and the second sub-shading part 7-2 that are furthest apart satisfies: 0.9×(P1-P4)≤P12≤1.1×(P1-P4).

[0264] In some embodiments, as shown in Figure 10, P12 = (P1 - P4). This can better alleviate or even eliminate moiré patterns.

[0265] It should be noted that during the manufacturing process of the display panel, when factors such as process errors occur, there may be a situation where P12 ≠ (P1-P4). Within a reasonable range of process errors, P12 can still alleviate or even eliminate moiré patterns if it satisfies the condition that 0.9×(P1-P4)≤P12≤1.1×(P1-P4).

[0266] In some embodiments, as shown in FIG10, in the first direction a1, the distance P13 between the two sides of the first sub-shading part 7-1 and the second sub-shading part 7-2 that are furthest apart satisfies: 0.9×(i'×P3-P5)≤P13≤1.1×(i'×P3-P5); where P5 is the width of the second shading part 302 in the first direction a1, and i' is greater than or equal to 1.

[0267] In some embodiments, as shown in Figure 10, P13 = i' × P3 - P5. This can better alleviate or even eliminate moiré patterns.

[0268] It should be noted that during the manufacturing process of the display panel, when factors such as process errors occur, there may be a situation where P13 ≠ i'×P3-P5.

[0275] It should be noted that during the manufacturing process of the display panel, factors such as process errors may occur, resulting in... Under the condition that, within a reasonable process error range, P10 satisfies: P11 satisfies: It can still alleviate or even eliminate moiré patterns.

[0276] In some embodiments, as shown in FIG10, the line connecting the endpoints of the two closest edges extending along the first direction a1 located in the first sub-shading part 7-1 and the second sub-shading part 7-2, respectively, at one of the extension directions, and the normal direction 6 of the first direction a1, the angle θ4 between them is equal to θ1.

[0277] When the first sub-shading part and the second sub-shading part are located on both sides of the second shading part in the first direction, and the orthographic projections of the first shading part are adjacent, the sub-shading parts meet the above conditions, which can further alleviate or even eliminate moiré patterns, while avoiding affecting the size of the opening area as much as possible.

[0278] It should be noted that, in the display device shown in Figure 10, within a beam splitting structure 401, the number of complete second light-shielding portions 302 passing through the first preset length L1 on the third direction a3 is 1 or 2, and the number of complete third light-shielding portions 303 passing through the first preset length L1 on the third direction a3 is 1 or 0. That is, the sum of the number of complete second light-shielding portions 302 and complete third light-shielding portions 303 passing through the first preset length L1 on the third direction a3 is 2, i = 1, 2, i' = 2.

[0279] Alternatively, in some embodiments, as shown in FIG11, when the third light-shielding part 303 includes multiple sub-light-shielding parts 7, the third light-shielding part 303 may also include multiple sub-light-shielding parts 7 with unequal areas. Of course, in specific implementations, as shown in FIG12, the third light-shielding part 303 may also include one sub-light-shielding part 7.

[0280] In some embodiments, as shown in Figures 11 and 12, one pair of sides of the sub-shading portion 7 is parallel to the first direction a1, and the other pair of sides of the sub-shading portion 7 is perpendicular to the first direction a1.

[0281] The sum H of the side lengths H of all the first portions 13 included in the third light-shielding portion 303 in the first direction a1 satisfies:

[0282] In the direction perpendicular to the first direction a1, the side length P10 of the first part 13 satisfies:

[0283] i' is greater than or equal to 1.

[0284] In some embodiments, It can better alleviate or even eliminate moiré patterns.

[0285] It should be noted that during the manufacturing process of the display panel, factors such as process errors may occur, resulting in... Under the condition that H is within a reasonable process error range, H satisfies: P10 satisfies: It can still alleviate or even eliminate moiré patterns.

[0288] In some embodiments, as shown in FIG11, in the direction of the normal 6 of the first direction a1, the distance P12 between the two sides of the first sub-shading part 7-1 and the second sub-shading part 7-2 that are furthest apart satisfies: 0.9×(P1-P4)≤P12≤1.1×(P1-P4);

[0289] In the first direction a1, the distance P13 between the two furthest sides of the first sub-shading part 7-1 and the second sub-shading part 7-2 satisfies: 0.9×(P3-P5)≤P13≤1.1×(P3-P5); where P5 is the width of the second shading part 302 in the first direction a1, and i' is greater than or equal to 1.

[0290] The line connecting the endpoints of the two closest edges extending along the first direction a1 located in the first sub-shading part 7-1 and the second sub-shading part 7-2, respectively, and the normal direction 6 of the first direction a1, has an angle θ4 equal to θ1.

[0291] It should be noted that, in the display device shown in Figures 11 and 12, within a beam splitting structure 401, the number of complete second light-shielding portions 302 passing through the first preset length L1 on the third direction a3 is 1 or 2, and the number of complete third light-shielding portions 303 passing through the first preset length L1 on the third direction a3 is 1 or 0.

[0292] In some embodiments, P12 = P1-P4, P13 = P3-P5. This can better alleviate or even eliminate moiré patterns.

[0293] It should be noted that during the manufacturing process of the display panel, when factors such as process errors occur, there may be situations where P12≠(P1-P4) and P13≠P3-P5.

[0294] In some embodiments, the third light-shielding portion is located in the same layer as the first light-shielding portion. That is, the light-shielding layer also includes the third light-shielding portion.

[0295] Alternatively, in some embodiments, the light-shielding layer does not include a third light-shielding portion.

[0296] In some embodiments, the gate and the first signal line are disposed in the same layer, and the film layer is a metal layer.

[0297] In some embodiments, the source, drain, and second signal line are disposed in the same layer, and the film layer is also a metal layer.

[0298] In some embodiments, the third light-shielding portion is disposed on the same layer as at least one of the light-shielding pattern, the first signal line, and the source electrode. Since both the light-shielding pattern and the metal layer have light-shielding properties, the light-shielding effect can be achieved by disposing the third light-shielding portion on the same layer as at least one of the light-shielding pattern, the gate electrode, and the source electrode.

[0299] In some embodiments, to simplify the wiring of the display panel, the third light-shielding part is disposed on the same layer as the light-shielding pattern.

[0300] In some embodiments, when the first signal line is multiplexed as the second light-shielding part, the third light-shielding part and the second light-shielding part are located on the same layer. When the third light-shielding part and the second light-shielding part are located on the same layer, as shown in Figures 9 to 12, the orthographic projection of the sub-light-shielding part 7 perpendicular to the display panel 1 does not overlap with the orthographic projection of the second light-shielding part 302 perpendicular to the display panel 1. That is, the sub-light-shielding part 7 only includes the first part 13.

[0301] Alternatively, in some embodiments, when the first signal line is multiplexed as the second light-shielding part, the third light-shielding part and the second light-shielding part are located on different layers. When the third light-shielding part and the second light-shielding part are located on different layers, in some embodiments, as shown in Figures 9 to 12, the orthographic projection of the sub-light-shielding part 7 perpendicular to the display panel 1 does not overlap with the orthographic projection of the light-shielding layer 3 perpendicular to the display panel 1. That is, the sub-light-shielding part 7 only includes the first part 13.

[0302] Alternatively, when the third light-shielding part and the second light-shielding part are located on different layers, in some embodiments, as shown in FIG13, the sub-light-shielding part 7 further includes: a second part 14;

[0303] The second part 14 is projected perpendicularly to the display panel 1 and falls into the projection of the light-shielding layer 3 perpendicularly to the display panel 1.

[0304] In some embodiments, as shown in FIG13, the third light-shielding part 303 includes two sub-light-shielding parts 7 with equal areas;

[0305] In the first direction a1, the two sub-light-shielding parts 7 of the third light-shielding part 303 are respectively located on both sides of the second light-shielding part 302 in the orthographic projection perpendicular to the display panel 1 in the orthographic projection perpendicular to the display panel 1 in the orthographic projection perpendicular to the display panel 1 in the first direction a1; the second part 14 overlaps with the second light-shielding part 302 in the orthographic projection perpendicular to the display panel 1 in the first direction a1.

[0306] In some embodiments, as shown in FIG13, the projected area S' of the sub-shielding portion 7 in the direction perpendicular to the display panel 1 satisfies:

[0307] in, or P1 is the arrangement period of pixel strip 2; P3 is the arrangement period of second light-shielding part 302 in the first direction a1; P4 is the width of first light-shielding part 301 in the direction perpendicular to the first direction a1; P5 is the width of second light-shielding part 302 in the first direction a1; i is the number of complete second light-shielding parts 302 passing through the first preset length L1 in the third direction a3 within a beam splitting structure 401, and i is a positive integer.

[0308] In some embodiments, It can better alleviate or even eliminate moiré patterns.

[0309] It should be noted that during the manufacturing process of the display panel, factors such as process errors may occur, resulting in... Under the condition that, within a reasonable range of process error, S' satisfies: It can still alleviate or even eliminate moiré patterns.

[0310] In some embodiments, as shown in FIG13, one pair of sides of the sub-shading portion 7 is parallel to the first direction a1, and the other pair of sides of the sub-shading portion 7 is perpendicular to the first direction a1.

[0311] The side length P15 of the light-shielding part 7 in the first direction a1 satisfies:

[0312] The side length P16 of the light-shielding part 7 perpendicular to the first direction a1 satisfies:

[0313] It should be noted that, in the display device shown in Figure 13, within a beam splitting structure 401, the number of complete second light-shielding portions 302 passing through the first preset length L1 in the third direction a3 is 1 or 2, and the number of complete third light-shielding portions 303 passing through the first preset length L1 in the third direction a3 is 1 or 0. That is, the sum of the number of complete second light-shielding portions 302 and complete third light-shielding portions 303 passing through the first preset length L1 in the third direction a3 is 2, i' = 2.

[0314] In some embodiments, It can better alleviate or even eliminate moiré patterns.

[0315] It should be noted that during the manufacturing process of the display panel, factors such as process errors may occur, resulting in... Under the condition that, within a reasonable process error range, P15 satisfies: P16 satisfies: It can still alleviate or even eliminate moiré patterns.

[0316] In some embodiments, as shown in Figures 10 to 13, the orthographic projection of the first portion 13 in the direction perpendicular to the display panel 1 is also adjacent to the orthographic projection of the second light-shielding portion 302 in the direction perpendicular to the display panel 1.

[0317] In some embodiments, as shown in Figures 7 to 13, θ2 = θ1. This can further reduce crosstalk in the displayed view in 3D display mode.

[0318] It should be noted that Figures 5 to 13 illustrate examples where the sub-pixel is non-rectangular and one pair of its sides is not perpendicular to the first direction a1. Alternatively, in some embodiments, as shown in Figures 14 and 15, the sub-pixel 201 includes a pair of first sides 5 extending perpendicular to the first direction a1, and the second light-shielding portion 302 extends perpendicular to the first direction a1, i.e., θ2 = θ3 = 0°.

[0319] In some embodiments, in FIG14, the first direction a1 is the vertical direction Y. Specifically, the number of scan lines is half the number of sub-pixels included in a pixel bar; one scan line corresponds to two rows of sub-pixels.

[0320] In some embodiments, in FIG15, the first direction a1 is the horizontal direction X. Specifically, the number of data lines is half the number of sub-pixels included in a pixel bar; one data line corresponds to two columns of sub-pixels.

[0321] In some embodiments, when θ2 = θ3 = 0°, the third direction is perpendicular to the first direction.

[0322] Alternatively, in some embodiments, when θ2 = θ3 = 0°, the angle between the third direction and the first direction can also be greater than 0° and less than 90°.

[0323] In some embodiments, within a pixel strip, subpixels emit light uniformly in the direction intersecting with the subpixels. This avoids moiré patterns and improves display quality.

[0324] However, in practice, subpixels often emit light unevenly in the direction they intersect within a pixel strip. When one end of each pixel strip is on the same straight line, moiré patterns can easily appear, affecting the display effect.

[0325] In some embodiments, within a pixel strip, in the direction intersecting with the sub-pixel, the sub-pixel emits light non-uniformly, and θ1 = θ2; the line connecting one end of the multiple pixel bars in the display panel is not a straight line. This helps to alleviate and eliminate moiré patterns.

[0326] In some embodiments, the line connecting one end of any two adjacent pixel strips lies on a different straight line from the normal in the first direction. That is, there is a relative displacement between any two adjacent pixel strips in the first direction, which can periodically compensate for the brightness uniformity of sub-pixels and help alleviate and eliminate moiré patterns.

[0327] In some embodiments, as shown in FIG16, the plurality of pixel strips 2 are divided into a plurality of compensation groups 15; the compensation group 15 includes N repeating units 16; the repeating unit 16 includes a plurality of pixel strips 2 with different emission colors.

[0328] In the first direction a1, the ratio of the distance P14 between the starting point of the first sub-pixel 201 in each pixel strip of the repeating unit 16 and the preset starting point B2 to the arrangement period P2 of the sub-pixel 201. Where k is an integer greater than or equal to 1 and less than or equal to N, C is an integer greater than 0, and E is an integer greater than or equal to 0 and less than N.

[0329] It should be noted that when Vk is not 0 and When Vk is +, it means that the starting point of the first sub-pixel 201 in each pixel strip has a displacement relative to the preset starting point B2 in the positive upward direction of the first direction; when Vk is not 0 and When the value is -, it means that the starting point of the first sub-pixel 201 in each pixel strip has a displacement relative to the preset starting point B2 in the negative direction of the first direction. In Figure 16, the upward direction is defined as the positive direction a1+ of the first direction a1, and the downward direction is defined as the negative direction a1- of the first direction a1.

[0330] In some embodiments, the preset starting point B2 is the starting point of the first sub-pixel 201 in the pixel bar when Vk = 0.

[0331] In some embodiments, C = 1; in each compensation group 15, the multiple Vk corresponding to the N repeating units 16 form an arithmetic sequence, and the common difference of the arithmetic sequence is 1 / N.

[0332] The display device provided in this embodiment divides periodically arranged repeating units into multiple compensation groups. Within each compensation group, the ratio of the distance between the starting point of the first sub-pixel in the pixel bar and a preset starting point to the sub-pixel arrangement period is Vk. The multiple Vk corresponding to N repeating units form an arithmetic sequence. Thus, within each compensation group, any two adjacent pixel bars have a relative displacement in a first direction, which can periodically compensate for the brightness uniformity of the sub-pixels, which is beneficial for alleviating and eliminating moiré patterns.

[0333] Specifically, when C = 1, Vk is one of the following: -(N-1) / N, -(N-2) / N, ..., -1 / N, 0, 1 / N, ..., (N-2) / N, (N-1) / N.

[0334] In some embodiments, as shown in FIG16, N=3, that is, the compensation group 15 includes 3 repeating units 16. Vk is one of the following: -2 / 3, -1 / 3, 0, 1 / 3, 2 / 3. The V1, V2, V3 corresponding to the 3 repeating units 16 form an arithmetic sequence, which can be any of the following: (-2 / 3, -1 / 3, 0), (-1 / 3, 0, 1 / 3), (0, 1 / 3, 2 / 3).

[0335] It should be noted that k does not represent the sequence number of the repeating units in a compensation group in the second direction. The Vk values ​​corresponding to the repeating units in the compensation group only need to satisfy the above-mentioned arithmetic sequence requirement. One type of arithmetic sequence of N values ​​can be arbitrarily assigned to the N repeating units in the compensation group. Taking N=3 as an example, there are 6 ways to assign Vk to the 3 repeating units: It can be Vk=V1 for the pixel strip in the first repeating unit, Vk=V2 for the pixel strip in the second repeating unit, and Vk=V3 for the pixel strip in the third repeating unit; or, it can be Vk=V1 for the pixel strip in the first repeating unit, Vk=V3 for the pixel strip in the second repeating unit, and Vk=V2 for the pixel strip in the third repeating unit; or, it can be Vk=V2 for the pixel strip in the first repeating unit, Vk=V1 for the pixel strip in the second repeating unit, and Vk=V2 for the pixel strip in the third repeating unit. The pixel bar corresponds to Vk = V3; or, it can be the pixel bar in the first repeating unit corresponding to Vk = V2, the pixel bar in the second repeating unit corresponding to Vk = V3, and the pixel bar in the third repeating unit corresponding to Vk = V1; or, it can be the pixel bar in the first repeating unit corresponding to Vk = V3, the pixel bar in the second repeating unit corresponding to Vk = V2, and the pixel bar in the third repeating unit corresponding to Vk = V1; or, it can be the pixel bar in the first repeating unit corresponding to Vk = V3, the pixel bar in the second repeating unit corresponding to Vk = V1, and the pixel bar in the third repeating unit corresponding to Vk = V2.

[0336] In some embodiments, in FIG. 16, in a compensation group 15, in the first direction a1, the distance P14 between the starting point of the first sub-pixel 201 of the pixel strip in the first repeating unit 16 and the preset starting point B2 is 0; the distances P14-2 between the starting point of the first sub-pixel 201 of the pixel strip in the second repeating unit 16 and the preset starting point B2, and the distances P14-3 between the starting point of the first sub-pixel 201 of the pixel strip in the third repeating unit 16 and the preset starting point B2 are both greater than 0, and P14-3 is greater than P14-2. The Vk corresponding to the three pixel strips is (0, 1 / 3, 2 / 3).

[0337] In some embodiments, in a pixel strip 2, in the direction intersecting with sub-pixel 201, sub-pixel 201 emits light non-uniformly, and or θ1 = θ2;

[0338] To mitigate or even eliminate moiré patterns, the angle θ1 between the third direction a3 and the normal 6 direction of the first direction a1 satisfies:

[0339] Where Q is an integer greater than or equal to 2.

[0340] In some embodiments,

[0341] It should be noted that during the manufacturing process of the display panel, factors such as process errors may occur, resulting in... Under the condition that θ1 satisfies the reasonable process error range, It can still alleviate or even eliminate moiré patterns.

[0342] In some embodiments, to further eliminate moiré patterns, when θ1 satisfies At the same time, it can also be set such that: within a beam splitting structure, the number of complete second light-blocking parts 302 passing through any first preset length L1 on the third direction a3 is equal.

[0343] In some embodiments, to avoid color separation, when θ1 satisfies Simultaneously, it can also be set to: the centers of the first sub-pixel, the second sub-pixel, and the third sub-pixel are collinear in the third direction a3. That is, any straight line along the third direction a3 passes through the center of the first sub-pixel, the center of the second sub-pixel, and the center of the third sub-pixel.

[0344] In some embodiments, as shown in FIG17, the ratio of the distance P14 between the starting point of the first sub-pixel 201 in the pixel strip 2 and the preset starting point B2 to the arrangement period P2 of the sub-pixel 201 in the first direction a1 is... Where k is an integer greater than or equal to 1 and less than or equal to 3, C is an integer greater than 0, and E is an integer greater than or equal to 0 and less than 3.

[0345] This ensures that the centers of the first, second, and third sub-pixels are collinear in the third direction, avoiding color separation between different sub-pixels in 3D display mode.

[0346] It should be noted that when Vk is not 0 and When Vk is +, it means that the starting point of the first sub-pixel 201 in each pixel strip has a displacement relative to the preset starting point B2 in the positive upward direction of the first direction; when Vk is not 0 and When the value is -, it means that the starting point of the first sub-pixel 201 in each pixel strip has a displacement relative to the preset starting point B2 in the negative direction of the first direction. In Figure 17, the upward direction is defined as the positive direction a1+ of the first direction a1, and the downward direction is defined as the negative direction a1- of the first direction a1.

[0347] In some embodiments, the preset starting point B2 is the starting point of the first sub-pixel 201 in the pixel bar when Vk = 0.

[0348] In some embodiments, C = 1; in each repeating unit 16, the multiple Vk corresponding to the 3 pixel bars 2 form an arithmetic sequence, and the common difference of the arithmetic sequence is...

[0349] The display device provided in this embodiment is equivalent to treating a repeating unit as a compensation group. Within each repeating unit, the ratio of the distance between the starting point of the first sub-pixel in the pixel bar and the preset starting point to the sub-pixel arrangement period is Vk. Furthermore, the multiple Vk values ​​corresponding to the three pixel bars in the repeating unit form an arithmetic sequence. Thus, within each repeating unit, any two adjacent pixel bars have a relative displacement in the first direction, which can periodically compensate for the brightness uniformity of the sub-pixels, thereby helping to alleviate and eliminate moiré patterns.

[0350] Specifically, when C = 1, Vk is one of the following: -(2) / 3Q, -(1) / 3Q, 0, 1 / 3Q, ..., 2 / 3Q.

[0351] In some embodiments, Q = 3. Vk is one of the following: -2 / 9, -1 / 9, 0, 1 / 9, 2 / 9. The V1, V2, V3 corresponding to the 3 pixel bars form an arithmetic sequence, which can be any of the following: (-2 / 9, -1 / 9, 0), (-1 / 9, 0, 1 / 9), (0, 1 / 9, 2 / 9).

[0352] It should be noted that k does not represent the sequence number of the pixel strip in the repeating unit in the second direction. Within the repeating unit, the Vk values ​​corresponding to the pixel strips only need to satisfy the aforementioned arithmetic sequence requirement. One type of arithmetic sequence of three values ​​can be arbitrarily assigned to the three pixel strips in the repeating unit. Taking Q=3 as an example, there are six possible allocations of Vk corresponding to the three pixel strips: Vk=V1 for the pixel strip in the first repeating unit, Vk=V2 for the pixel strip in the second repeating unit, and Vk=V3 for the pixel strip in the third repeating unit; or, Vk=V1 for the pixel strip in the first repeating unit, Vk=V3 for the pixel strip in the second repeating unit, and Vk=V2 for the pixel strip in the third repeating unit; or, Vk=V2 for the pixel strip in the first repeating unit, Vk=V1 for the pixel strip in the second repeating unit, and Vk=V2 for the pixel strip in the third repeating unit. The pixel corresponding to the pixel strip is Vk = V3; or, it can be Vk = V2 for the pixel strip in the first repeating unit, Vk = V3 for the pixel strip in the second repeating unit, and Vk = V1 for the pixel strip in the third repeating unit; or, it can be Vk = V3 for the pixel strip in the first repeating unit, Vk = V2 for the pixel strip in the second repeating unit, and Vk = V1 for the pixel strip in the third repeating unit; or, it can be Vk = V3 for the pixel strip in the first repeating unit, Vk = V1 for the pixel strip in the second repeating unit, and Vk = V2 for the pixel strip in the third repeating unit.

[0353] In some embodiments, in FIG17, in a repeating unit 16, in the first direction a1, the distance P14 between the starting point of the first sub-pixel 201 in the first pixel strip and the preset starting point B2 is 0, the distance P14-2 between the starting point of the first sub-pixel 201 in the second pixel strip and the preset starting point B2, and the distance P14-3 between the starting point of the first sub-pixel 201 in the third pixel strip and the preset starting point B2 are both greater than 0, and P14-3 is greater than P14-2. The Vk corresponding to the three pixel strips is (0, -1 / 9, -2 / 9).

[0354] In some embodiments, in order to further eliminate moiré patterns, At the same time, it can also be set such that: within a beam splitting structure, the number of complete second light-blocking parts passing through any first preset length L1 on the third direction a3 is equal.

[0355] Alternatively, in some embodiments, within a pixel strip 2, in the direction intersecting with sub-pixel 201, sub-pixel 201 emits light non-uniformly, and As shown in Figure 18, θ2≠θ1;

[0356] To mitigate or even eliminate moiré patterns, the angle θ1 between the third direction a3 and the normal 6 direction of the first direction a1, and the angle θ2 between the first side 5 and the normal 6 direction of the first direction a1 satisfy: 0.9×P2≤P1×(|tanθ1|-|tanθ2|)≤1.1×P2.

[0357] In some embodiments, P1×(|tanθ1|-|tanθ2|)=P2.

[0358] It should be noted that during the manufacturing process of the display panel, when factors such as process errors occur, the situation may occur where P1×(|tanθ1|-|tanθ2|)≠P2. Within a reasonable range of process errors, θ2 satisfies: 0.9×P2≤P1×(|tanθ1|-|tanθ2|)≤1.1×P2, which can still alleviate or even eliminate moiré patterns.

[0359] In some embodiments, in order to further eliminate moiré patterns, while ensuring that 0.9×P2≤P1×(|tanθ1|-|tanθ2|)≤1.1×P2, it can also be set such that within a beam-splitting structure, the number of complete second light-shielding portions passing through any first preset length L1 on a third direction a3 is equal.

[0360] The following example illustrates how the equal number of complete second-shielding sections of arbitrary first-preset length L1 along a third-direction a3 within a beam-splitting structure, satisfying P1×(|tanθ1|-|tanθ2|)=P2, can significantly alleviate moiré patterns. The sub-pixels emit light non-uniformly, as shown in Figure 19. The angular spectrum obtained by fully opening all pixels is shown in Figure 20. Calculations show that, at a viewing distance of 1.5 meters, with an integrated angular brightness scan and comparison based on a pupil distance of 4 mm, the moiré pattern is 6.22%. Based on the above display device, with the left and right eyes open respectively, the left and right eye angular spectra at 0° are shown in Figure 21, at 15° in Figure 23, and at 28° in Figure 24. Crosstalk calculations based on a 65 mm interpupillary distance yielded the following crosstalk rates: 3.22% at 0°, 2.39% at 15°, and 22.43% at 28°. While a low-crosstalk 3D display effect can be achieved, the moiré pattern is relatively large. When P1×(|tanθ1|-|tanθ2|)=P2, and the number of complete second light-blocking parts passing through any first preset length L1 on the third direction a3 within a beam-splitting structure is equal, the angular spectrum of fully opened pixels is obtained as shown in Figure 24. After calculation, at a viewing distance of 1.5 meters, with the pupil size of 4 mm, the angular brightness integral scan comparison shows a moiré pattern of 0.23%, achieving a 3D display effect with low crosstalk and low moiré pattern. Furthermore, as can be seen from Figures 20 to 23, the angle at which no repeated viewpoints appear is 56°. Therefore, the display device provided in this embodiment can also satisfy multiple people watching at the same time, and each person sees different 3D display content.

[0361] In some embodiments, as shown in FIG3, the display panel 1 further includes a plurality of first spacers 104 located between the array substrate 101 and the opposing substrate 102.

[0362] Specifically, the first spacer can be the main spacer, and the display panel can also include a plurality of auxiliary spacers located between the array substrate and the opposing substrate, the thickness of the auxiliary spacers being less than the thickness of the main spacers.

[0375] In the second substrate 1702, the fourth light-shielding portion 18 is located between the fourth substrate 17021 and the fourth insulating layer 17023.

[0390] In summary, the display device provided in this disclosure has a smaller number of opening areas than the number of sub-pixels. At least in one direction, the number of opening areas corresponding to a pixel strip is less than the number of sub-pixels included in the pixel strip. Since the signal lines are located in the light-shielding area, the number of signal lines corresponding to a pixel strip is less than the number of sub-pixels included in the pixel strip in at least one direction, thus reducing the number of signal lines. Signal lines typically need to be electrically connected to bonding pins, which also reduces the number of bonding pins, saving costs and simplifying wiring.
