Description

Display devices and their manufacturing methods and electronic products

[0001] This application claims priority to Chinese Patent Application No. 202411487842.4, filed on October 23, 2024, the disclosure of which is incorporated herein by reference in its entirety. Technical Field

[0002] This disclosure relates to a display device, a method of manufacturing the display device, and an electronic product. Background Technology

[0003] With the continuous development of display technology, three-dimensional (3D) display technology is receiving increasing attention. 3D display technology is a technology capable of presenting stereoscopic images, allowing users to perceive depth, layers, and stereoscopic effects on a two-dimensional screen, making the displayed image more realistic and lifelike. 3D display technology can be widely used in film, television, games, medicine, education, and many other fields. The basic principle of 3D display technology is generally based on the stereoscopic vision characteristics of the human eye. That is, when the human eye observes an object through its left and right eyes, due to the slight difference in viewing angle, it can perceive the depth, layers, and stereoscopic effects of the object. Therefore, 3D display technology uses various methods to allow the left and right eyes to receive left-eye and right-eye images with a certain parallax. After these images are received by the left and right eyes, the brain superimposes and fuses the image information to construct a three-dimensional visual display effect.

[0004] On the other hand, we live in a three-dimensional space, and most of human experience comes from the perception of depth information. Because 3D displays possess depth information, they can achieve many functions that 2D displays lack. However, most electronic products today still operate at the 2D display level. This is related to the level of image processing technology in the past. With technological advancements, image processing technology has progressed rapidly. Current image processing hardware has achieved miniaturization, high efficiency, and low heat generation. Simultaneously, various optical solutions for 3D displays are emerging, laying the foundation for the widespread adoption of 3D display technology. Summary of the Invention

[0005] This disclosure provides a display device, a method for manufacturing the display device, and an electronic product. In this display device, the size of the beam-splitting unit in the second direction is equal to the size of the pixel island in the second direction. The orthographic projection of each beam-splitting unit on the display panel covers Q pixel islands. Therefore, the light emitted by the pixel units in the Q pixel islands is split by the beam-splitting unit above, allowing the left-eye image to enter the user's left eye and the right-eye image to enter the user's right eye, thereby enabling the display device to achieve 3D display. Furthermore, since the first included angle α satisfies tanα=M / K, the pixel units in the same pixel unit row are located at the same beam-splitting position in the same beam-splitting structure, and multiple beam-splitting units can be continuously arranged, thereby enabling the display device to form a continuous light-emitting area. In addition, since each beam-splitting unit extends along a third direction, the display device can achieve 3D display in different orientations. Furthermore, since the first angle between the third direction and the second direction is greater than 0 degrees and less than 90 degrees, and the first angle α satisfies the following formula: tanα=M / K, the display device can select the value of K for different sizes, thereby adjusting the extension direction of the beam-splitting structure in the beam-splitting unit while ensuring that the beam-splitting unit can cover M pixel units at different positions. This allows display devices of different sizes to have good 3D display effects in different orientations. On the other hand, since the line connecting the brightness centers of the N pixel units included in each pixel unit row also extends along the third direction D3, and the first angle α between the third direction D3 and the second direction D2 satisfies the formula: tanα=M / K, when a straight line is displayed on the Q pixel islands covered by the beam-splitting unit, the extension direction of the straight line is the same as the extension direction of each beam-splitting structure, thereby avoiding defects such as moiré patterns.

[0006] At least one embodiment of this disclosure provides a display device, comprising:

[0007] A display panel includes: a plurality of pixel units arranged in an array along a first direction and a second direction; the plurality of pixel units are divided into a plurality of pixel islands arranged in an array along a third direction and the second direction; the size of each pixel island in the first direction is equal to the size of each pixel island in the second direction; and the first direction and the second direction are perpendicular to each other.

[0008] Each pixel island includes M rows of pixel units arranged sequentially along the second direction, and each row of pixel units includes N pixel units arranged along the third direction, where M and N are positive integers greater than or equal to 1;

[0009] A beam-splitting component is located on the light-emitting side of the display panel and includes multiple beam-splitting units. Each beam-splitting unit includes P beam-splitting structures, and each beam-splitting structure extends along the third direction, where P is a positive integer greater than or equal to 1.

[0010] In this configuration, the size of the beam-splitting unit in the second direction is equal to the size of the pixel island in the second direction, and the orthographic projection of each beam-splitting unit on the display panel covers Q pixel islands, where Q is a positive integer greater than or equal to 1.

[0011] In each of the pixel islands, the line connecting the brightness centers of the N pixel units included in each of the pixel unit rows also extends along the third direction, and the first angle between the third direction and the second direction is greater than 0 degrees and less than 90 degrees.

[0012] For example, in a display device provided in an embodiment of this disclosure, the first included angle α satisfies the following formula tanα=M / K, where K is a positive integer greater than or equal to 1.

[0013] For example, in a display device provided in an embodiment of this disclosure, each pixel unit includes a strip-shaped pixel electrode extending along a fourth direction, and the line connecting the centers of the N strip-shaped pixel electrodes of the N pixel units included in each row of pixel units also extends along the third direction. The N strip-shaped pixel electrodes of the N pixel units included in each row of pixel units extend in the same direction, and the second included angle between the fourth direction and the second direction is greater than 0 degrees and less than 90 degrees.

[0014] For example, in a display device provided in one embodiment of this disclosure, each pixel unit includes an effective light-emitting area and black matrix portions located on both sides of the effective light-emitting area in the first direction.

[0015] In each of the pixel islands, the M effective light-emitting areas of the M pixel units arranged along the second direction form a strip-shaped pixel light-emitting area extending along the second direction, and the M black matrix portions of the M pixel units arranged along the second direction form a black matrix extending along the second direction, with the black matrix located on both sides of the strip-shaped pixel light-emitting area in the first direction.

[0016] For example, in a display device provided in one embodiment of this disclosure, the value of M can be 11, 12, 13 or 16.

[0017] For example, in a display device provided in one embodiment of this disclosure, the fourth direction is the same as the third direction, and the first included angle and the second included angle are the same.

[0018] For example, in a display device provided in one embodiment of this disclosure, in each of the pixel islands, the strip-shaped pixel light-emitting area includes a plurality of gate lines arranged along the second direction, and the dimension c of the black matrix in the first direction satisfies the following formula: [a-tan(90-α) / X*d]-3 <c<[a-tan(90-α) / X*d]+3,

[0019] Where a is the size of the pixel unit in the first direction, d is the distance between two adjacent gate lines in the second direction, X is a positive integer greater than or equal to 1, and the units of a, c, and d are micrometers.

[0020] For example, in a display device provided in one embodiment of this disclosure, the value of X is 1, 2 or 3.

[0021] For example, in a display device provided in an embodiment of this disclosure, in each of the pixel islands, the strip-shaped pixel light-emitting area includes a plurality of gate lines arranged along the second direction, each of the gate lines extending along the fifth direction, and the second included angle β between the fifth direction and the first direction satisfies the following formula: arctan[(|X*d-(ac)tan(90-α)|) / (ac)]-3<β <arctan[(|X*d-(a-c)tan(90-α)|) / (a- c)]+3,

[0022] Where a is the size of the pixel unit in the first direction, c is the size of the black matrix in the first direction, d is the distance between two adjacent gate lines in the second direction, and X is a positive integer greater than or equal to 1.

[0023] For example, in a display device provided in one embodiment of this disclosure, in each of the pixel islands, the strip-shaped pixel light-emitting area includes a plurality of gate lines arranged along the second direction, and each of the strip-shaped pixel light-emitting areas further includes a light-shielding structure located between two adjacent gate lines.

[0024] The total length of the portion where any two virtual straight lines extending along the third direction intersect with the grid line and the light-shielding structure in the strip-shaped pixel light-emitting area is equal.

[0025] For example, in a display device provided in one embodiment of this disclosure, the display panel includes a substrate, the orthographic projection of the light-shielding structure on the substrate is connected to the orthographic projection of the black matrix on the substrate, and the dimension z1 of the light-shielding structure in the first direction satisfies the following formula: e*tan(α)-3 <z1<e*tan(α)+3,

[0026] The dimension z2 of the light-shielding structure in the second direction satisfies the following formula: T*d-(a–c)tan(90-α)-3 <z2<T*d-(a–c)tan(90-α)+3,

[0027] Where a is the size of the pixel unit in the first direction, c is the size of the black matrix in the first direction, d is the distance between two adjacent gate lines in the second direction, e is the size of the gate line in the second direction, T is the maximum number of gate lines that the virtual straight line can overlap, and the units of a, c, d, and e are micrometers.

[0028] For example, in a display device provided in an embodiment of this disclosure, the light-shielding structure includes a plurality of sub-light-shielding structures, the size of each sub-light-shielding structure in the first direction is the same as the size of the light-shielding structure in the first direction, and the size of the light-shielding structure in the second direction is equal to the sum of the sizes of the plurality of sub-light-shielding structures in the second direction.

[0029] For example, in a display device provided in one embodiment of this disclosure, the display panel includes a substrate, the orthographic projection of the light-shielding structure on the substrate is connected to the orthographic projection of the grating line on the substrate, and the dimension z1 of the light-shielding structure in the first direction satisfies the following formula: e*tan(α)-3 <z1<e*tan(α)+3,

[0030] The dimension z2 of the light-shielding structure in the second direction satisfies the following formula: T*d-(a–c)tan(90-α)-3 <z2<T*d-(a–c)tan(90-α)+3,

[0031] Where a is the size of the pixel unit in the first direction, c is the size of the black matrix in the first direction, d is the distance between two adjacent gate lines in the second direction, e is the size of the gate line in the second direction, T is the maximum number of gate lines that the virtual straight line can overlap, and the units of a, c, d, and e are micrometers.

[0032] For example, in a display device provided in one embodiment of this disclosure, the light-shielding structure is disposed on the same layer as the grating lines.

[0033] For example, in a display device provided in one embodiment of this disclosure, the display panel further includes a light-shielding layer located on the substrate, and the light-shielding structure is located on the light-shielding layer.

[0034] For example, in a display device provided in one embodiment of this disclosure, each pixel island includes N pixel unit columns, each pixel unit column includes M pixel units, and Y pixel islands arranged along the third direction form a pixel group, the pixel group including Y*N pixel unit columns.

[0035] In the pixel group, the pixel electrode of the N pixel unit column in the (i+1)th pixel island is displaced by 1 / Y pixel pitch along the second direction relative to the pixel electrode of the N pixel unit column in the ith pixel island. The pixel pitch is the distance between the geometric centers of two adjacent pixel electrodes in the second direction, where Y is a positive integer greater than or equal to 3 and i is a positive integer greater than or equal to 1 and less than or equal to Y.

[0036] For example, in a display device provided in one embodiment of this disclosure, the value of Y is 3, 4 or 5.

[0037] For example, in a display device provided in one embodiment of this disclosure, the fourth direction is different from the third direction, the strip-shaped pixel light-emitting area includes a plurality of gate lines arranged along the second direction, and the third included angle γ between the fourth direction and the second direction satisfies the following formula: arctan[(fb) / (ac)]-3<γ <arctan[(f-b) / (a-c)]+3,

[0038] Where a is the size of the pixel unit in the first direction, b is the size of the pixel unit in the second direction, c is the size of the black matrix in the first direction, f = (ac) / tanα, and the units of a, b, and c are micrometers.

[0039] For example, in a display device provided in one embodiment of this disclosure, the first included angle α between the third direction and the second direction also satisfies the following formula: arctan[(ac) / X*d]-3<α <arctan[(a-c) / X*d]+3,

[0040] Where a is the size of the pixel unit in the first direction, d is the distance between two adjacent gate lines in the second direction, c is the size of the black matrix in the first direction, X is a positive integer greater than or equal to 1, and the units of a, d, and c are micrometers.

[0041] For example, in a display device provided in an embodiment of this disclosure, the first included angle α satisfies the following formula: tanα=M / [K+(H / J)], where K is a positive integer greater than or equal to 1, J is a natural number greater than or equal to 2, and H is a natural number greater than or equal to 1 and less than or equal to J.

[0042] For example, in a display device provided in one embodiment of this disclosure, each pixel island includes N pixel unit columns, and each pixel unit column includes M pixel units.

[0043] In the pixel island, the pixel electrode of the (i+1)th pixel unit column is displaced by 1 / N pixel pitch relative to the pixel electrode of the ith pixel unit column along the second direction. The pixel pitch is the distance between the geometric centers of two adjacent pixel electrodes in the second direction, and i is a positive integer greater than or equal to 1 and less than or equal to N.

[0044] At least one embodiment of this disclosure also provides an electronic product that includes the display device described in any of the preceding claims.

[0045] At least one embodiment of this disclosure also provides a method for manufacturing a display device, which includes:

[0046] A display panel is formed, the display panel including a plurality of pixel units arranged in an array along a first direction and a second direction, the plurality of pixel units being divided into a plurality of pixel islands arranged in an array along a third direction and the second direction, the size of each pixel island in the first direction being equal to the size of the pixel island in the second direction, the first direction and the second direction being perpendicular to each other, each pixel island including M rows of pixel units arranged sequentially along the second direction, each row of pixel units including N pixel units arranged along the third direction, where M and N are positive integers greater than or equal to 1;

[0047] A beam-splitting component is disposed on the light-emitting side of the display panel. The beam-splitting component includes multiple beam-splitting units, and each beam-splitting unit includes P beam-splitting structures. Each beam-splitting structure extends along the third direction, where P is a positive integer greater than or equal to 1.

[0048] In this configuration, the size of the beam-splitting unit in the second direction is equal to the size of the pixel island in the second direction, and the orthographic projection of each beam-splitting unit on the display panel covers Q pixel islands, where Q is a positive integer greater than or equal to 1.

[0049] In each of the pixel islands, the line connecting the brightness centers of the N pixel units included in each of the pixel unit rows also extends along the third direction, and the first angle between the third direction and the second direction is greater than 0 degrees and less than 90 degrees.

[0081] 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. Based on the described embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0082] 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.

[0083] 3D display technologies include: glasses-based 3D display technology, glasses-free 3D display technology, holographic 3D display technology, and volumetric 3D display technology. Glasses-based 3D display technology uses glasses to allow the user's left eye to receive the left-eye image and the right eye to receive the right-eye image, thus synthesizing a 3D image in the user's brain. Glasses-free 3D display technology uses only a screen to allow the user's left eye to receive the left-eye image and the right eye to receive the right-eye image, thus synthesizing a 3D image in the user's brain. Holographic 3D display technology records and reproduces the amplitude and phase information of light waves from an object to form a realistic 3D image. Volumetric 3D display technology uses volume scanning or static volume imaging techniques to directly generate 3D images in space.

[0084] Glasses-based 3D display technology can be divided into color-separation 3D, polarized 3D, and active shutter 3D. Color-separation 3D uses glasses with different colored filters to provide different colors for the left and right eyes, creating a sense of depth through color differences. However, this method is prone to color distortion at the edges of the image, and the 3D effect is relatively poor. Polarized 3D utilizes the principle that light has a "polarization direction," decomposing the original image into two sets of images with different polarization directions (e.g., vertically polarized light and horizontally polarized light). Polarized glasses then allow the left and right eyes to receive these two sets of images with different polarization directions, thus synthesizing a stereoscopic image in the brain. This technology has a moderate cost and good image quality, but it requires high brightness from the display device. Active shutter 3D increases the refresh rate, splitting the image in half frame by frame to create two sets of images corresponding to the left and right eyes. Combined with active shutter 3D glasses, this ensures that the left and right eyes see the corresponding image at the correct time. This technology can maintain the original resolution of the image and achieve a true full HD 3D effect, but the glasses are expensive and have certain requirements for the device's refresh rate. It is clear that glasses-based 3D display technology not only requires users to wear glasses, but also has various drawbacks.

[0085] Glasses-free 3D display technology can be divided into three types: parallax barrier 3D, lenticular lens 3D, and directional light source 3D. Parallax barrier 3D separates the image for the left and right eyes by placing a parallax barrier composed of a liquid crystal layer and a polarizing film in front of the display screen, allowing the viewer to see 3D images. Directional light source 3D uses two sets of LEDs and a fast-response LCD panel to allow 3D content to enter the viewer's left and right eyes in a sequential manner, creating parallax and thus a sense of depth. Lens-based 3D adds a lenticular lens in front of the liquid crystal display, placing the image plane of the liquid crystal display on the focal plane of the lenticular lens. This allows each eye to see different sub-pixels when viewing the liquid crystal display from different angles, thus creating a sense of depth.

[0086] For lenticular lens 3D display technology, a good 3D display effect can be achieved by forming a continuously emitting display panel and combining it with lenticular lenses. On the other hand, for mobile terminal products, both horizontal and vertical screen orientations are commonly used by users, therefore, the terminal product needs to achieve 3D display from different viewing angles. This can be achieved by forming tilted pixels and prisms, thus enabling 3D display from multiple viewing angles simultaneously. However, the above design is prone to defects such as rainbow patterns and moiré patterns.

[0087] In response, this disclosure provides a display device including a display panel and a beam-splitting assembly. The display panel includes: a plurality of pixel units arranged in an array along a first direction and a second direction, the plurality of pixel units being divided into a plurality of pixel islands arranged in an array along a third direction and the second direction, the size of each pixel island in the first direction being equal to the size of the pixel island in the second direction, the first direction and the second direction being perpendicular to each other, each pixel island including M rows of pixel units arranged sequentially along the second direction, and each row of pixel units including N pixel units arranged along the third direction, where M and N are positive integers greater than or equal to 1; the beam-splitting assembly... The component is located on the light-emitting side of the display panel and includes multiple beam-splitting units. Each beam-splitting unit includes P beam-splitting structures, and each beam-splitting structure extends along the third direction, where P is a positive integer greater than or equal to 1. The size of the beam-splitting unit in the second direction is equal to the width of the pixel island in the second direction. The orthographic projection of each beam-splitting unit on the display panel covers Q pixel islands, where Q is a positive integer greater than or equal to 1. In each pixel island, the line connecting the brightness centers of N pixel units included in each pixel unit row also extends along the third direction. The first angle between the third direction and the second direction is greater than 0 degrees and less than 90 degrees.

[0088] In the display device provided in this embodiment, the size of the beam-splitting unit in the second direction is equal to the size of the pixel island in the second direction. The orthographic projection of each beam-splitting unit on the display panel covers Q pixel islands. Therefore, the light emitted by the pixel units in the Q pixel islands is split by the beam-splitting unit above, causing the left-eye image to enter the user's left eye and the right-eye image to enter the user's right eye, thereby enabling the display device to achieve 3D display. Furthermore, since the line connecting the brightness centers of the N pixel units included in each pixel unit row also extends along the third direction, the pixel units in the same pixel unit row are located at the same beam-splitting position in the same beam-splitting structure, and multiple beam-splitting units can be continuously arranged, thereby enabling the display device to form a continuous light-emitting area. In addition, since each beam-splitting unit extends along the third direction, the display device can achieve 3D display in different orientations. For example, the user can achieve 3D display when using the display device vertically and horizontally. On the other hand, since the line connecting the brightness centers of the N pixel units included in each pixel unit row also extends along the third direction D3, when a straight line is displayed on the Q pixel islands covered by the beam splitting unit, the extension direction of the straight line is the same as the extension direction of each beam splitting structure, thereby avoiding defects such as moiré patterns.

[0089] At least one embodiment of this disclosure also provides an electronic product including the aforementioned display device. Since the display device can achieve 3D display, the electronic product can also achieve 3D display; furthermore, the electronic product exhibits good 3D display effects from different orientations. On the other hand, the electronic product also avoids defects such as moiré patterns.

[0090] This disclosure also provides a method for manufacturing a display device, comprising: forming a display panel, the display panel including a plurality of pixel units arranged in an array along a first direction and a second direction, the plurality of pixel units being divided into a plurality of pixel islands arranged in an array along a third direction and the second direction, the size of each pixel island in the first direction being equal to the size of the pixel island in the second direction, the first direction and the second direction being perpendicular to each other, each pixel island including M rows of pixel units arranged sequentially along the second direction, each row of pixel units including N pixel units arranged along the third direction, where M and N are positive integers greater than or equal to 1; in the display... A beam-splitting component is provided on the light-emitting side of the panel. The beam-splitting component includes multiple beam-splitting units, each beam-splitting unit includes P beam-splitting structures, each beam-splitting structure extends along the third direction, where P is a positive integer greater than or equal to 1. The size of the beam-splitting unit in the second direction is equal to the size of the pixel island in the second direction. The orthographic projection of each beam-splitting unit on the display panel covers Q pixel islands, where Q is a positive integer greater than or equal to 1. In each pixel island, the line connecting the brightness centers of N pixel units included in each pixel unit row also extends along the third direction. The first angle between the third direction and the second direction is greater than 0 degrees and less than 90 degrees.

[0091] In the manufacturing method of the display device provided in this disclosure embodiment, the size of the beam-splitting unit in the second direction is equal to the size of the pixel island in the second direction. The orthographic projection of each beam-splitting unit on the display panel covers Q pixel islands. Therefore, the light emitted by the pixel units in the Q pixel islands is split by the beam-splitting unit above, causing the left-eye image to enter the user's left eye and the right-eye image to enter the user's right eye, thereby enabling the display device to achieve 3D display. Furthermore, since the line connecting the brightness centers of the N pixel units included in each pixel unit row also extends along the third direction, the pixel units in the same pixel unit row are located at the same beam-splitting position in the same beam-splitting structure, and multiple beam-splitting units can be continuously arranged, thereby enabling the display device to form a continuous light-emitting area. In addition, since each beam-splitting unit extends along the third direction, the display device can achieve 3D display in different orientations. For example, the user can achieve 3D display when using the display device vertically and horizontally. On the other hand, since the line connecting the brightness centers of the N pixel units included in each pixel unit row also extends along the third direction D3, when a straight line is displayed on the Q pixel islands covered by the beam splitting unit, the extension direction of the straight line is the same as the extension direction of each beam splitting structure, thereby avoiding defects such as moiré patterns.

[0092] The display device, the method of manufacturing the display device, and the electronic product provided in the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0093] Figure 1 is a plan view of a display device provided in an embodiment of the present disclosure; Figure 2 is a partial cross-sectional view of a display device provided in an embodiment of the present disclosure.

[0094] As shown in Figures 1 and 2, the display device 300 includes a display panel 100 and a beam splitting assembly 200. The display panel 100 includes a plurality of pixel units 110 arranged in an array along a first direction D1 and a second direction D2. The plurality of pixel units 110 are divided into a plurality of pixel islands 120 arranged in an array along a third direction D3 and a second direction D2. Each pixel island 120 includes M rows 131 of pixel units arranged sequentially along the second direction D2, and each row 131 includes N pixel units 110 arranged along the third direction D3. The size of each pixel island 120 in the first direction D1 is equal to the size of the pixel island 120 in the second direction D2. M and N are positive integers greater than or equal to 1. The first direction D1 and the second direction D2 are perpendicular to each other, and the third direction D3 is different from the first direction D1. Therefore, each row of pixel units is tilted. It should be noted that the above-mentioned pixel unit refers to a unit that can be independently controlled for light emission, and can usually be considered as a sub-pixel.

[0095] For example, as shown in Figure 1, since each pixel island 120 includes M pixel unit rows 131 arranged sequentially along the second direction D2, and each pixel unit row 131 includes N pixel units 110 arranged along the third direction D3, each pixel island 120 can also be regarded as including N pixel unit columns 132, and each pixel unit column 132 includes M pixel units 110 arranged along the second direction.

[0096] For example, as shown in Figure 1, to clearly illustrate the arrangement of pixel units within a pixel island, each pixel island 120 includes six rows 131 of pixel units arranged sequentially along the second direction D2, and each row 131 of pixel units includes three pixel units 110 arranged along the third direction D3; that is, M is 6 and N is 3. However, the situation shown in Figure 1 is merely exemplary, and the embodiments of this disclosure include, but are not limited to, M and N, which may also be set to other values.

[0097] For example, the first direction D1 mentioned above can be a row direction or the extension direction of the grid lines, and the second direction D2 mentioned above can be a column direction or the extension direction of the data lines. Additionally, when the display device is generally rectangular in shape, the first direction D1 and the second direction D2 can also be the length and width directions of the display device. Of course, the embodiments disclosed herein are not limited to these, and the first and second directions can be set as appropriate, as long as they are perpendicular to each other.

[0098] As shown in Figures 1 and 2, the beam-splitting assembly 200 is located on the light-emitting side of the display panel 100 and includes multiple beam-splitting units 210. Each beam-splitting unit 210 includes P beam-splitting structures 220. Each beam-splitting structure 200 extends along a third direction D3, where P is a positive integer greater than or equal to 1. That is, the extension direction of each beam-splitting structure 200 is consistent with the arrangement direction of the pixel unit row 131. The size of the beam-splitting unit 210 in the second direction D2 is equal to the size of the pixel island 120 in the second direction D2. The orthographic projection of each beam-splitting unit 210 on the display panel 100 covers Q of the pixel islands, where Q is a positive integer greater than or equal to 1.

[0099] For example, as shown in Figure 2, each beam splitting unit 210 includes one beam splitting structure 220, that is, P = 1. However, the embodiments of this disclosure include, but are not limited to, that each beam splitting unit 210 may also include 2, 3, 4, 5, or 6 beam splitting structures 220, and the value of P can be set as needed.

[0100] As shown in Figures 1 and 2, in each pixel island 120, the line connecting the brightness centers of the N pixel units 110 included in each pixel unit row 131 also extends along the third direction D3.

[0101] In the display device provided in this embodiment, the size of the beam-splitting unit in the second direction is equal to the size of the pixel island in the second direction. The orthographic projection of each beam-splitting unit on the display panel covers Q pixel islands. Therefore, the light emitted by the pixel units in the Q pixel islands is split by the beam-splitting unit above, causing the left-eye image to enter the user's left eye and the right-eye image to enter the user's right eye, thereby enabling the display device to achieve 3D display. Furthermore, since the line connecting the brightness centers of the N pixel units included in each pixel unit row also extends along the third direction, the pixel units in the same pixel unit row are located at the same beam-splitting position in the same beam-splitting structure, and multiple beam-splitting units can be continuously arranged, thereby enabling the display device to form a continuous light-emitting area. In addition, since each beam-splitting unit extends along the third direction, the display device can achieve 3D display in different orientations. For example, the user can achieve 3D display when using the display device vertically and horizontally.

[0102] On the other hand, since the line connecting the brightness centers of the N pixel units included in each pixel unit row also extends along the third direction D3, when a straight line is displayed on the Q pixel islands covered by the beam splitting unit, the extension direction of the straight line is the same as the extension direction of each beam splitting structure, thereby avoiding defects such as moiré patterns.

[0103] In some examples, the first included angle between the third direction D3 and the second direction D2 is greater than 0 degrees and less than 90 degrees, and the first included angle α satisfies the following formula: tanα=M / K, where K is a positive integer greater than or equal to 1. On the one hand, by satisfying the above formula, the line connecting the brightness centers of the N pixel units 110 included in each pixel unit row 131 also extends along the third direction D3. On the other hand, the display device can select the value of K for different sizes, thereby adjusting the extension direction of the beam-splitting structure in the beam-splitting unit while ensuring that the beam-splitting unit can cover M pixel units at different positions, so that display devices of different sizes can have good 3D display effects in different orientations.

[0104] It is worth noting that in the display device provided in this embodiment, since the pixel units are arranged in an array along the first direction D1 and the second direction D2, the display device can also be used for 2D display. That is, the display device can switch between 2D display mode and 3D display mode. When the display device is used for 2D display, its resolution is higher. In some examples, the beam splitting structure 220 described above can be a cylindrical lens, and each beam splitting unit 210 can include multiple parallel cylindrical lenses.

[0105] For example, the cylindrical lens mentioned above is a liquid crystal lens. In specific implementations, when the cylindrical lens is a zoomable liquid crystal lens, the radius of curvature of the cylindrical lens can be different at different viewing angles, resulting in relatively small crosstalk between adjacent viewpoints without significant changes due to fluctuations in the radius of curvature, and a large viewing range with zero crosstalk between the left and right eyes. Of course, the embodiments of this disclosure include, but are not limited to, this; the beam-splitting structure can also be a geometric lens, a diffractive lens, a liquid lens, or other structural devices capable of controlling the light emission direction of sub-pixels.

[0106] In some examples, as shown in Figure 1, the size of each pixel island 120 in the first direction D1 ranges from 60 micrometers to 180 micrometers. For example, when the display device is a medium-sized display, the size of each pixel island 120 in the first direction D1 can range from 90 micrometers to 150 micrometers, such as 106 micrometers, 136 micrometers, etc.; when the display device is a large display, the size of each pixel island 120 in the first direction D1 can range from 150 micrometers to 180 micrometers, such as 152 micrometers, 175 micrometers, etc.; when the display device is a small display, the size of each pixel island 120 in the first direction D1 can range from 60 micrometers to 90 micrometers, such as 60 micrometers, 80 micrometers, etc.

[0107] In some examples, as shown in Figure 1, the size of each pixel island 120 in the second direction D2 is approximately equal to the size of each pixel island 120 in the first direction D1. Therefore, the size of each pixel island 120 in the second direction D2 ranges from 60 micrometers to 180 micrometers.

[0108] In some examples, as shown in Figure 1, in each pixel island 120, the size of each pixel unit 110 in the first direction D1 ranges from 25 micrometers to 40 micrometers, for example 30 micrometers or 35 micrometers; the size of each pixel unit 110 in the second direction D2 ranges from 5 micrometers to 10 micrometers, for example 8 micrometers.

[0109] In some examples, as shown in Figures 1 and 2, each pixel unit 110 includes a strip pixel electrode 112 extending along the fourth direction D4. The line connecting the centers of the N strip pixel electrodes 112 of the N pixel units 110 included in each pixel unit row 131 also extends along the third direction D3. The N strip pixel electrodes 112 of the N pixel units 110 included in each pixel unit row 131 extend in the same direction. The second included angle between the fourth direction D4 and the second direction D2 is greater than 0 degrees and less than 90 degrees.

[0110] In the display device provided in this example, since the line connecting the centers of the N strip pixel electrodes of the N pixel units included in each pixel unit row also extends along a third direction, and the N strip pixel electrodes of the N pixel units included in each pixel unit row extend in the same direction, each strip pixel electrode can be aligned with the strip pixel electrode in the same row by translation, thereby further avoiding defects such as moiré patterns. It should be noted that the pixel electrode is one of the main electrodes controlling light emission, and the shape and extension direction of the pixel electrode can determine the shape and extension direction of the effective light-emitting area of ​​the pixel unit.

[0111] In some examples, as shown in Figures 1 and 2, each pixel unit 110 includes an effective light-emitting area 110A and black matrix portions 110B located on both sides of the effective light-emitting area 110A in the first direction D1; in each pixel island 120, the M effective light-emitting areas 110A of the M pixel units 110 arranged along the second direction D2 form a strip-shaped pixel light-emitting area 140 extending along the second direction D2, and the M black matrix portions 110B of the M pixel units 110 arranged along the second direction D2 form a black matrix 150 extending along the second direction D2, with the black matrix 150 located on both sides of the strip-shaped pixel light-emitting area 140 in the first direction D1.

[0112] In the display device provided in this example, since the M effective light-emitting areas of the M pixel units arranged along the second direction form a strip-shaped pixel light-emitting area extending along the second direction D2, that is, no black matrix is ​​set between the effective light-emitting areas of adjacent pixel units in the second direction, the pixel density of the display device is greatly improved, thus making it suitable for 3D display. It should be noted that although no black matrix is ​​set between adjacent pixel units in the second direction, a grid line extending along the first direction is provided in the strip-shaped pixel light-emitting area.

[0113] In some examples, since no black matrix is ​​set between the effective light-emitting areas of adjacent pixel units in the second direction, the number of pixel units arranged along the second direction in a pixel island can be 11, 12, 13, and 16, that is, the value of M can be 11, 13, or 16. It should be noted that, in order to show the pixel electrodes more clearly, the number of pixel unit rows in the pixel island in FIG1 is relatively small, but the embodiments of this disclosure include, but are not limited to, that the number of pixel unit rows in a pixel island can be 11, 12, 13, and 16, or even more, thereby increasing the pixel density and making it suitable for 3D display.

[0114] For example, when M is 11, according to the formula tanα=M / K, the first angle α between the third direction D3 and the second direction D2 can be: Arctan(11 / 15), Arctan(11 / 12), Arctan(11 / 9), Arctan(11 / 6), Arctan(11 / 3).

[0115] For example, when M is 12, according to the formula tanα=M / K, the first angle α between the third direction D3 and the second direction D2 can be: Arctan(4 / 5), Arctan(1), Arctan(4 / 3), Arctan(2), Arctan(4).

[0116] For example, when M is 13, according to the formula tanα=M / K, the first angle α between the third direction D3 and the second direction D2 can be: Arctan(13 / 15), Arctan(13 / 12), Arctan(13 / 9), Arctan(13 / 6), Arctan(13 / 3).

[0117] For example, when M is 16, according to the formula tanα=M / K, the first angle α between the third direction D3 and the second direction D2 can be: Arctan(16 / 15), Arctan(16 / 12), Arctan(16 / 9), Arctan(16 / 6), Arctan(16 / 3).

[0118] In some examples, as shown in Figure 1, in a pixel island 120, each pixel unit row 131 includes three pixel units 110 arranged along a third direction D3; that is, the value of N mentioned above is 3. For example, the three pixel units 110 included in each pixel unit row 131 can be three pixel units 110 that emit different colors of light, such as a pixel unit emitting red light, a pixel unit emitting green light, and a pixel unit emitting blue light. Of course, the embodiments of this disclosure include, but are not limited to, the value of N mentioned above can also be other suitable values.

[0119] In some examples, in the formula tanα=M / K satisfied by the first included angle α, K takes the value of a positive integer greater than or equal to 1. The display device can select the value of K for different sizes, thereby adjusting the extension direction of the beam-splitting structure in the beam-splitting unit while ensuring that the beam-splitting unit can cover M pixel units at different positions, so that display devices of different sizes can have good 3D display effects in different orientations.

[0120] In some examples, as shown in Figure 1, the fourth direction D4 and the third direction D3 described above are the same, and the first included angle and the second included angle are the same. That is, the extension direction of the pixel unit row in each pixel island, the extension direction of the beam-splitting structure, and the extension direction of the strip pixel electrode in each pixel unit are the same. Therefore, the display device can further avoid the generation of moiré patterns. Of course, embodiments of this disclosure include, but are not limited to, the fourth direction and the third direction described above may also be different.

[0121] In some examples, as shown in FIG2, the display panel 100 includes an array substrate 100A, an opposing substrate 100B, and a liquid crystal layer 100C located between the array substrate 100A and the opposing substrate 100B. The pixel electrode 112 described above may be disposed on the array substrate 100A, and the black matrix 150 described above may be disposed on the array substrate 100A or the opposing substrate 100B.

[0122] Figure 3 is a plan view of another display device provided in an embodiment of this disclosure. As shown in Figure 3, the display device 300 includes a display panel 100 and a beam splitting component 200; the display panel 100 includes a plurality of pixel units 110 arranged in an array along a first direction D1 and a second direction D2. The plurality of pixel units 110 are divided into a plurality of pixel islands 120 arranged in an array along a third direction D3 and a second direction D2. Each pixel island 120 includes M rows 131 of pixel units arranged sequentially along the second direction D2, and each row 131 of pixel units includes N pixel units 110 arranged along the third direction D3. The size of each pixel island 120 in the first direction D1 is equal to the size of the pixel island 120 in the second direction D2. M and N are positive integers greater than or equal to 1. The first direction D1 and the second direction D2 are perpendicular to each other, and the third direction D3 is different from the first direction D1. Therefore, each row of pixel units is tilted. It should be noted that the above-mentioned pixel unit refers to a unit that can be independently controlled for light emission, and can usually be considered as a sub-pixel.

[0123] As shown in Figure 3, the beam splitting component 200 is located on the light-emitting side of the display panel 100 and includes multiple beam splitting units 210. Each beam splitting unit 210 includes P beam splitting structures 220. Each beam splitting structure 200 extends along a third direction D3, where P is a positive integer greater than or equal to 1. That is, the extension direction of each beam splitting structure 200 is consistent with the arrangement direction of the pixel unit row 131. The size of the beam splitting unit 210 in the second direction D2 is equal to the size of the pixel island 120 in the second direction D2. The orthographic projection of each beam splitting unit 210 on the display panel 100 covers Q of the pixel islands, where Q is a positive integer greater than or equal to 1.

[0124] As shown in Figure 3, in each pixel island 120, the line connecting the brightness centers of the N pixel units 110 included in each pixel unit row 131 also extends along the third direction D3. The first included angle between the third direction D3 and the second direction D2 is greater than 0 degrees and less than 90 degrees.

[0125] As shown in Figure 3, each pixel unit 110 includes a strip pixel electrode 112 extending along the fourth direction D4. The line connecting the centers of the N strip pixel electrodes 112 of the N pixel units 110 included in each pixel unit row 131 also extends along the third direction D3. The N strip pixel electrodes 112 of the N pixel units 110 included in each pixel unit row 131 extend in the same direction. The second included angle between the fourth direction D4 and the second direction D2 is greater than 0 degrees and less than 90 degrees.

[0126] As shown in Figure 3, the fourth direction D4 mentioned above is different from the third direction D3 mentioned above.

[0127] In the display device provided in this embodiment, the size of the beam-splitting unit in the second direction is equal to the size of the pixel island in the second direction. The orthographic projection of each beam-splitting unit on the display panel covers Q pixel islands. Therefore, the light emitted by the pixel units in the Q pixel islands is split by the beam-splitting unit above, causing the left-eye image to enter the user's left eye and the right-eye image to enter the user's right eye, thereby enabling the display device to achieve 3D display. Furthermore, since the line connecting the brightness centers of the N pixel units included in each pixel unit row also extends along the third direction, the pixel units in the same pixel unit row are located at the same beam-splitting position in the same beam-splitting structure, and multiple beam-splitting units can be continuously arranged, thereby enabling the display device to form a continuous light-emitting area. In addition, since each beam-splitting unit extends along the third direction, the display device can achieve 3D display in different orientations. For example, the user can achieve 3D display when using the display device vertically and horizontally. On the other hand, since the line connecting the brightness centers of the N pixel units included in each pixel unit row also extends along the third direction D3, when a straight line is displayed on the Q pixel islands covered by the beam splitting unit, the extension direction of the straight line is the same as the extension direction of each beam splitting structure, thereby avoiding defects such as moiré patterns.

[0128] On the other hand, although the fourth direction is different from the third direction, since the line connecting the brightness centers of the N pixel units included in each pixel unit row also extends along the third direction D3, when a straight line is displayed in the Q pixel islands covered by the beam splitting unit, the extension direction of the straight line is the same as the extension direction of each beam splitting structure, thereby avoiding defects such as moiré patterns.

[0129] In some examples, the first included angle between the third direction D3 and the second direction D2 is greater than 0 degrees and less than 90 degrees, and the first included angle α satisfies the following formula: tanα=M / K, where K is a positive integer greater than or equal to 1. On the one hand, by satisfying the above formula, the line connecting the brightness centers of the N pixel units 110 included in each pixel unit row 131 also extends along the third direction D3. On the other hand, the display device can select the value of K for different sizes, thereby adjusting the extension direction of the beam-splitting structure in the beam-splitting unit while ensuring that the beam-splitting unit can cover M pixel units at different positions, so that display devices of different sizes can have good 3D display effects in different orientations.

[0130] For example, as shown in Figure 3, to clearly illustrate the arrangement of pixel units within a pixel island, each pixel island 120 includes five rows 131 of pixel units arranged sequentially along the second direction D2, and each row 131 of pixel units includes three pixel units 110 arranged along the third direction D3; that is, M is 5 and N is 3. However, the situation shown in Figure 1 is merely exemplary, and the embodiments of this disclosure include, but are not limited to, this, and M and N may also be set to other values.

[0131] In the research, the inventors of the present application also noticed that: since there are still gate lines in the strip-shaped pixel light-emitting area, and the gate lines have a certain blocking effect on light. At this time, if the integral brightness of the virtual straight line extending in the third direction in the strip-shaped pixel light-emitting area is different, moiré patterns with light and dark intervals will also be generated. In response to this, the embodiments of the present disclosure also perform targeted design on the above problems to avoid moiré patterns caused by gate lines. It should be noted that for clarity, the gate lines are not shown in FIG. 1, and the position of the gate lines in FIG. 1 can be referred to FIG. 4.

[0132] FIG. 4 is a partial plan schematic view of a pixel island in a display device provided by an embodiment of the present disclosure. As shown in FIG. 4, in each pixel island 120, the strip-shaped pixel light-emitting area 140 includes a plurality of gate lines 142 arranged along the second direction D2, and the size c of the black matrix 150 in the first direction D1 satisfies the following formula: [a - tan(90 - α) / X * d] - 3 < c < [a - tan(90 - α) / X * d] + 3,

[0133] where a is the size of the pixel unit 110 in the first direction D1, d is the distance between two adjacent gate lines 142 in the second direction D2, X is a positive integer greater than or equal to 1, and the units of a, c, and d are micrometers. It should be noted that the distance between two adjacent gate lines mentioned above refers to the distance between the center lines of two adjacent gate lines.

[0134] In the display device provided in the above example, since the size of the black matrix in the first direction satisfies the above formula [a - tan(90 - α) / X * d] - 3 < c < [a - tan(90 - α) / X * d] + 3, if X = 1, any virtual straight line extending in the third direction in the strip-shaped pixel light-emitting area will overlap with one gate line. At this time, the integral brightness of any two virtual straight lines extending in the third direction in the strip-shaped pixel light-emitting area is the same; if X = 2, any virtual straight line extending in the third direction in the strip-shaped pixel light-emitting area will overlap with two gate lines. At this time, the integral brightness of any two virtual straight lines extending in the third direction in the strip-shaped pixel light-emitting area is the same; if X = 3, any virtual straight line extending in the third direction in the strip-shaped pixel light-emitting area will overlap with three gate lines. At this time, the integral brightness of any three virtual straight lines extending in the third direction in the strip-shaped pixel light-emitting area is the same, and so on. Thus, since the size of the black matrix in the first direction satisfies the above formula [a - tan(90 - α) / X * d] - 3 < c < [a - tan(90 - α) / X * d] + 3, the integral brightness of any two virtual straight lines extending in the third direction in the strip-shaped pixel light-emitting area is always the same, thereby avoiding the generation of brightness differences and thus avoiding the generation of moiré patterns with light and dark intervals.

[0135] It should be noted that in the above formula, 3 is the process error range. Therefore, when the process error is small, the size c of the black matrix 150 in the first direction D1 can satisfy: [a - tan(90 - α) / X * d] - 1 < c < [a - tan(90 - α) / X * d] + 1, and even c = a - tan(90 - α) / X * d.

[0136] It should be noted that the settings and relative positional relationships of the pixel islands, strip-shaped light-emitting regions, and black matrices in the embodiments shown in FIG. 3 can be the same as those in the embodiments shown in FIG. 1 or FIG. 3. Therefore, the settings of the above-mentioned pixel islands, strip-shaped pixel light-emitting regions, and black matrices can be referred to the relevant descriptions in FIG. 1 or FIG. 3, and will not be elaborated here.

[0137] In some examples, in [a - tan(90 - α) / X * d] - 3 < c < [a - tan(90 - α) / X * d] + 3, the value of X can be 1, 2, or 3. Of course, the embodiments of the present disclosure include but are not limited to this.

[0138] In some examples, as shown in FIG. 4, two adjacent pixel units 110 in the first direction D1 share the black matrix 150 between the two pixel units 110. Therefore, the size of the pixel unit 110 in the first direction D1 is equal to the sum of the size of the effective light-emitting region 110A in the first direction D1 and half of the size of the two black matrices 150 in the first direction, that is, the size of the pixel unit 110 in the first direction D1 is equal to the sum of the size of the effective light-emitting region 110A in the first direction D1 and the size of one black matrix 150 in the first direction.

[0139] In some examples, as shown in FIG. 4, the gate lines 142 in each pixel light-emitting region 140 extend along the first direction D1; that is to say, the extension direction of the gate lines in the display device provided in this example is not changed.

[0140] FIG. 5A is a partial plan view of a pixel island in another display device provided by an embodiment of the present disclosure; FIG. 5B is a partial plan view of a pixel island in another display device provided by an embodiment of the present disclosure. As shown in FIG. 5A and FIG. 5B, in each pixel island 120, the strip-shaped pixel light-emitting region 140 includes a plurality of gate lines 142 arranged along the second direction D2, and each gate line 142 extends along the fifth direction D5. The second included angle β between the fifth direction D5 and the first direction D1 satisfies the following formula: arctan[(|X * d - (a - c)tan(90 - α)|) / (a - c)] - 3 < β < arctan[(|X * d - (a - c)tan(90 - α)|) / (a - c)] + 3.

[0141] Where, a is the size of the pixel unit 110 in the first direction D1, c is the size of the black matrix 150 in the first direction D1, d is the distance between two adjacent gate lines 142 in the second direction D2, and X is a positive integer greater than or equal to 1.

[0142] In the display device provided in this example, by changing the extending direction of the gate lines in the strip-shaped pixel light-emitting area and making the second included angle β between the fifth direction and the first direction satisfy arctan[(|X*d-(a-c)tan(90-α)|) / (a-c)]-3 < β < arctan[(|X*d-(a-c)tan(90-α)|) / (a-c)]+3. If X = 1, any virtual straight line extending along the third direction will overlap with one gate line in the strip-shaped pixel light-emitting area. At this time, the integrated brightness of any two virtual straight lines extending along the third direction in the strip-shaped pixel light-emitting area is the same. If X = 2, any virtual straight line extending along the third direction will overlap with two gate lines in the strip-shaped pixel light-emitting area. At this time, the integrated brightness of any two virtual straight lines extending along the third direction in the strip-shaped pixel light-emitting area is the same. If X = 3, any virtual straight line extending along the third direction will overlap with three gate lines in the strip-shaped pixel light-emitting area. At this time, the integrated brightness of any two virtual straight lines extending along the third direction in the strip-shaped pixel light-emitting area is the same, and so on. Thus, because the second included angle β between the fifth direction and the first direction satisfies arctan[(|X*d-(a-c)tan(90-α)|) / (a-c)]-3 < β < arctan[(|X*d-(a-c)tan(90-α)|) / (a-c)]+3, the integrated brightness of any two virtual straight lines extending along the third direction in the strip-shaped pixel light-emitting area is always the same, thereby avoiding the generation of brightness differences and thus avoiding the generation of bright and dark alternating moiré patterns. In addition, because the display device provided in this example does not change the width of the black matrix, it is possible to avoid the generation of bright and dark alternating moiré patterns while ensuring a relatively high aperture ratio.

[0143] It should be noted that in the display device provided in the above example, it is only required that the gate lines in the strip-shaped pixel light-emitting area extend along the fifth direction, while the gate lines in the area where the black matrix is located can extend in other directions. In addition, in the formula satisfied by the above second included angle β, 3 is the process error, and its unit is degree. Therefore, when the process error is small, the second included angle β between the fifth direction and the first direction can also satisfy arctan[(|X*d-(a-c)tan(90-α)|) / (a-c)]-1 < β < arctan[(|X*d-(a-c)tan(90-α)|) / (a-c)]+1, or even β = arctan[(|X*d-(a-c)tan(90-α)|) / (a-c)].

[0144] For example, as shown in Figure 5A, when X = 1, any virtual straight line extending along the third direction will overlap with a gate line 142 in the strip-shaped pixel light-emitting area 140. At this time, the integrated brightness of any two virtual straight lines extending along the third direction in the strip-shaped pixel light-emitting area 140 is the same, thereby avoiding brightness differences and thus avoiding the generation of alternating bright and dark moiré patterns.

[0145] For example, as shown in Figure 5B, when X = 2, any virtual straight line extending along the third direction will overlap with two gate lines 142 in the strip-shaped pixel light-emitting area 140. At this time, the integrated brightness of any two virtual straight lines extending along the third direction in the strip-shaped pixel light-emitting area 140 is the same, thereby avoiding brightness differences and thus avoiding the generation of alternating bright and dark moiré patterns.

[0146] Figure 6 is a partial planar schematic diagram of pixel islands in another display device according to an embodiment of this disclosure. As shown in Figure 6, in each pixel island 120, the strip-shaped pixel light-emitting area 140 includes a plurality of gate lines 142 arranged along a second direction. Each strip-shaped pixel light-emitting area 140 also includes a light-shielding structure 145 located between two adjacent gate lines 142. The total length of the overlapping portion of any two virtual straight lines extending along the third direction D3 with the gate lines 142 and the light-shielding structure 145 in the strip-shaped pixel light-emitting area 140 is equal. Thus, by adding a light-shielding structure between adjacent gate lines, the integrated brightness of any two virtual straight lines extending along the third direction in the strip-shaped pixel light-emitting area is always the same, thereby avoiding brightness differences and thus avoiding the generation of alternating bright and dark moiré patterns. In addition, since the display device provided in this example does not need to change the width of the black matrix, it can avoid the generation of alternating bright and dark moiré patterns while ensuring a high aperture ratio.

[0147] In some examples, as shown in Figure 6, the display panel 100 includes a substrate 101. The orthographic projection of the light-shielding structure 145 on the substrate 101 is connected to the orthographic projection of the black matrix 150 on the substrate 101. The dimension z1 of the light-shielding structure 145 in the first direction D1 satisfies the following formula: e*tan(α)-3 <z1<e*tan(α)+3,

[0148] The dimension z2 of the light-shielding structure 145 in the second direction D2 satisfies the following formula: T*d-(a–c)tan(90-α)-3 <z2<T*d-(a–c)tan(90-α)+3,

[0149] Where, a is the size of pixel unit 110 in the first direction D1, c is the size of the black matrix 150 in the first direction D1, d is the distance between two adjacent gate lines 142 in the second direction D2, e is the size of gate line 142 in the second direction D2, T is the maximum number of gate lines 142 that the virtual line can overlap, and the units of a, c, d, and e are micrometers.

[0150] In the display device provided in this example, by making the size of the light shielding structure in the first direction satisfy the formula e*tan(α) - 3 < z1 < e*tan(α) + 3, and the size of the light shielding structure in the second direction satisfy the formula T*d - (a – c)tan(90 - α) - 3 < z2 < T*d - (a – c)tan(90 - α) + 3, when the virtual line extending along the third direction D3 moves in the second direction in the strip-shaped pixel light-emitting area, the overlapping area of the virtual line with the light shielding structure and the gate line is always the same, so that the total length of the overlapping parts of any two virtual lines extending along the third direction with the gate line and the light shielding structure in the strip-shaped pixel light-emitting area is equal. Thus, the integral brightness of any two virtual lines extending along the third direction in the strip-shaped pixel light-emitting area is always the same, thereby avoiding the generation of brightness differences and avoiding the generation of moiré patterns with alternating light and dark.

[0151] It should be noted that in the above formula, 3 is the process error. Therefore, when the process error is small, the size of the light shielding structure in the first direction can satisfy e*tan(α) - 1 < z1 < e*tan(α) + 1, or even z1 = e*tan(α); the size of the light shielding structure in the second direction can satisfy T*d - (a – c)tan(90 - α) - 1 < z2 < T*d - (a – c)tan(90 - α) + 1, or even z2 = T*d - (a – c)tan(90 - α).

[0152] For example, as shown in FIG. 6, the light shielding structure 145 and the black matrix 150 can be provided in the same layer. For example, the light shielding structure 145 and the black matrix 150 can be formed through the same patterning process using the same film layer. Of course, the embodiments of the present disclosure include but are not limited to this, and the light shielding structure can also be formed in other film layers, as long as the orthographic projection of the light shielding structure on the substrate is connected to the orthographic projection of the black matrix on the substrate.

[0153] Figure 7 is a partial planar schematic diagram of a pixel island in another display device provided in an embodiment of this disclosure. Unlike the monolithic light-shielding structure 145 in Figure 6, as shown in Figure 7, the light-shielding structure 145 includes multiple sub-light-shielding structures 1450. The dimensions of each sub-light-shielding structure 1450 in the first direction D1 are the same as the dimensions of the light-shielding structure 145 in the first direction D1. The dimensions of the light-shielding structure 145 in the second direction D2 are equal to the sum of the dimensions of the multiple sub-light-shielding structures 1450 in the second direction D2. Therefore, when a virtual straight line extending along the third direction D3 moves along the second direction in the strip-shaped pixel light-emitting area, the area of ​​overlap between the virtual straight line and the light-shielding structure and the gate line is always the same, making the total length of the overlapping portions of any two virtual straight lines extending along the third direction with the gate line and the light-shielding structure in the strip-shaped pixel light-emitting area equal. Thus, the integrated brightness of any two virtual straight lines extending along the third direction in the strip-shaped pixel light-emitting area is always the same, thereby avoiding brightness differences and thus avoiding alternating bright and dark moiré patterns.

[0154] For example, as shown in Figure 7, the light-shielding structure 145 may include two sub-light-shielding structures 1450. These two sub-light-shielding structures 1450 are arranged in the second direction D2, that is, the two sub-light-shielding structures 1450 do not overlap in the second direction D2. In addition, one of the two sub-light-shielding structures 1450 is connected to the black matrix 150 on the left side of the strip-shaped pixel light-emitting area 140, and the other is connected to the black matrix 150 on the right side of the strip-shaped pixel light-emitting area 140.

[0155] In some examples, as shown in FIG7, the light-shielding structure 145 and the black matrix 150 can be disposed in the same layer. For example, the light-shielding structure 145 and the black matrix 150 can be formed by the same film layer through the same patterning process. Of course, the embodiments of this disclosure include, but are not limited to, the light-shielding structure can also be formed in other film layers, as long as the orthographic projection of the light-shielding structure on the substrate is connected to the orthographic projection of the black matrix on the substrate.

[0156] Figure 8 is a partial planar schematic diagram of a pixel island in another display device provided in an embodiment of this disclosure. Unlike the light-shielding structure shown in Figure 7, as shown in Figure 8, the display panel 100 includes a substrate 101. The orthographic projection of the light-shielding structure 145 on the substrate 101 is connected to the orthographic projection of the gate line 142 on the substrate 101. The dimension z1 of the light-shielding structure 145 in the first direction D1 satisfies the following formula: e*tan(α)-3 <z1<e*tan(α)+3,

[0157] The dimension z2 of the light-shielding structure 145 in the second direction D2 satisfies the following formula: T*d-(a–c)tan(90-α)-3 <z2<T*d-(a–c)tan(90-α),

[0158] Where, a is the size of the pixel unit 110 in the first direction D1, c is the size of the black matrix 150 in the first direction D1, d is the distance between two adjacent gate lines 142 in the second direction D2, e is the size of the gate line 142 in the second direction D2, T is the maximum number of gate lines 142 that the virtual line can overlap, and the units of a, c, d, and e are micrometers.

[0159] In the display device provided in this example, by making the size of the light-shielding structure in the first direction satisfy the formula e*tan(α)-3 < z1 < e*tan(α)+3, and the size of the light-shielding structure in the second direction satisfy the formula T*d-(a–c)tan(90-α)-3 < z2 < T*d-(a–c)tan(90-α), when the virtual line extending along the third direction D3 moves in the second direction in the strip-shaped pixel light-emitting area, the overlapping area of the virtual line with the light-shielding structure and the gate line is always the same, so that the total length of the overlapping parts of any two virtual lines extending along the third direction with the gate line and the light-shielding structure in the strip-shaped pixel light-emitting area is equal. Thus, the integral brightness of any two virtual lines extending along the third direction in the strip-shaped pixel light-emitting area is always the same, thereby avoiding the generation of brightness differences and thus avoiding the generation of moiré patterns with alternating light and dark.

[0160] It should be noted that in the above formula, 3 is the process error. Therefore, when the process error is small, the size of the light-shielding structure in the first direction can satisfy e*tan(α)-1 < z1 < e*tan(α)+1, or even z1 = e*tan(α); the size of the light-shielding structure in the second direction can satisfy T*d-(a–c)tan(90-α)-1 < z2 < T*d-(a–c)tan(90-α)+1, or even z2 = T*d-(a–c)tan(90-α).

[0161] In some examples, as shown in FIG. 8, the light-shielding structure 145 and the gate line 142 are provided on the same layer. For example, the light-shielding structure 145 and the gate line 142 are formed by the same patterning process using the same film layer. Of course, the embodiments of the present disclosure include but are not limited to this. The light-shielding structure can also be formed in other film layers, as long as the orthographic projection of the light-shielding structure on the substrate is connected to the orthographic projection of the gate line on the substrate.

[0162] Figure 9 is a partial planar schematic diagram of a pixel island in another display device provided in an embodiment of this disclosure. Unlike the light-shielding structure shown in Figure 8, as shown in Figure 9, the display panel 100 further includes a light-shielding layer 190 located on the substrate 101; in this case, the light-shielding structure 145 is located on the light-shielding layer 190. That is, a light-shielding layer is used to form the aforementioned light-shielding structure. It should be noted that pixel driving circuits are disposed on both sides of the strip-shaped pixel light-emitting area, and a light-shielding layer is typically disposed between the pixel driving circuit and the substrate to prevent external light from adversely affecting the pixel driving circuit.

[0163] In the research, the inventors of this application also noted that although the strip-shaped pixel light-emitting area does not have a black matrix, since the pixel electrodes in the strip-shaped pixel light-emitting area are arranged at intervals rather than continuously, there are areas with high light-emitting brightness and areas with low light-emitting brightness in the strip-shaped pixel light-emitting area. After being amplified by the beam-splitting structure, this regular uneven brightness is prone to forming moiré patterns.

[0164] For example, Figure 10 is a schematic diagram of the principle of generating moiré patterns in a display device. As shown in Figure 10, the beam-splitting structure 220 covers multiple pixel electrodes 112. Since the pixel electrodes 112 in the strip-shaped pixel light-emitting area 140 are spaced apart and not continuously arranged, there are areas with high light-emitting brightness and areas with low light-emitting brightness in the strip-shaped pixel light-emitting area 140. This regular uneven brightness is easily amplified by the beam-splitting structure 220, which can easily form moiré patterns.

[0165] Figure 11 is a plan view of another display device provided in an embodiment of the present disclosure. As shown in Figure 11, each pixel island 120 includes N pixel unit columns 132, each pixel unit column 132 includes M pixel units 110, and Y pixel islands 120 arranged along a third direction D3 form a pixel group 180, which includes Y*N pixel unit columns 132; in the pixel group 180, the pixel electrode 112 of the N pixel unit columns 132 in the (i+1)th pixel island 120 is displaced by 1 / Y pixel pitch relative to the pixel electrode 112 of the N pixel unit columns 132 in the ith pixel island 120 along a second direction D2, where the pixel pitch is the distance between the geometric centers of two adjacent pixel electrodes 112 in the second direction, Y is a positive integer greater than or equal to 3, and i is a positive integer greater than or equal to 1 and less than or equal to Y.

[0166] In the display device provided in this example, a pixel group can be considered as a repeating unit, and the Q pixel islands covered by the beam-splitting unit can form Q / Y repeating units. In each pixel group, the pixel electrodes of the N pixel unit columns in the (i+1)th pixel island are displaced by 1 / Y pixel pitch along the second direction D2 relative to the pixel electrodes of the N pixel unit columns in the ith pixel island. When a virtual straight line extending along the third direction passes through each pixel island, the overlap between the virtual straight line and the pixel electrodes in the pixel island is different, thereby avoiding the situation where one virtual straight line overlaps with N pixel electrodes in the pixel island, while another virtual straight line overlaps with 0 pixel electrodes in the pixel island. As mentioned above, the brightness of the area where the pixel electrode is located is higher, and the brightness of the edge of the pixel electrode or the area between the pixel electrodes is lower. Therefore, through the above settings, the display device can reduce the brightness difference between any two virtual straight lines extending along the third direction, which makes the light output brightness at different positions of the beam-splitting structure more uniform, thereby preventing regular brightness unevenness and avoiding moiré patterns.

[0167] For example, as shown in Figure 11, when Y = 3, the pixel electrodes 112 of the N pixel unit columns 132 in the second pixel island 120 are displaced by 1 / Y pixel pitch along the second direction D2 relative to the pixel electrodes 112 of the N pixel unit columns 132 in the first pixel island 120; the pixel electrodes 112 of the N pixel unit columns 132 in the third pixel island 120 are displaced by 1 / Y pixel pitch along the second direction D2 relative to the pixel electrodes 112 of the N pixel unit columns 132 in the second pixel island 120; when the virtual straight line extending along the third direction passes through the three pixel islands, the overlap between the virtual straight line and the pixel electrodes in the three pixel islands is different, thereby avoiding the situation where one virtual straight line overlaps with N pixel electrodes in the pixel island, while another virtual straight line overlaps with 0 pixel electrodes in the pixel island.

[0168] In some examples, the value of Y mentioned above can be 3, 4, or 5. Of course, embodiments of this disclosure include, but are not limited to, these.

[0169] Figure 12A is a partial planar schematic diagram of a pixel island in another display device provided in an embodiment of the present disclosure; Figure 12B is a schematic diagram of the extension direction of a pixel electrode in a display device provided in an embodiment of the present disclosure. As shown in Figures 12A and 12B, each pixel island includes M rows of pixel units arranged sequentially along the second direction D2, and each row of pixel units includes N pixel units 110 arranged along the third direction D3; each beam splitting structure 200 extends along the third direction D3, and each pixel unit 110 includes a strip-shaped pixel electrode 112 extending along the fourth direction D4.

[0170] As shown in FIG. 12, the above-mentioned fourth direction D4 is different from the above-mentioned third direction D3; the strip-shaped pixel light-emitting area 140 includes a plurality of gate lines 142 arranged along the second direction D2, and the third included angle γ between the fourth direction D4 and the second direction D2 satisfies the following formula: arctan[(f - b) / (a - c)] - 3 < γ < arctan[(f - b) / (a - c)] + 3,

[0171] where a is the size of the pixel unit 110 in the first direction D1, b is the size of the pixel unit 110 in the second direction D2, c is the size of the black matrix 150 in the first direction D1, f = (a - c) / tanα, and the units of a, b, and c are micrometers.

[0172] In the display device provided in this example, the virtual straight line extending along the third direction passes through the diagonal of a pixel unit. Therefore, this virtual straight line passes through the bright and dark areas of the entire pixel unit, that is, this virtual straight line passes through the area with higher brightness and the area with lower brightness of this pixel unit. Thus, the display device can reduce the brightness difference between any two virtual straight lines extending along the third direction, and also make the light-emitting brightness at different positions of the light-splitting structure more uniform, thereby preventing regular brightness non-uniformity and avoiding the generation of moiré patterns.

[0173] It should be noted that in the above formula, 3 is the process error. Therefore, when the process error is small, the third included angle γ between the fourth direction D4 and the second direction D2 can also satisfy: arctan[(f - b) / (a - c)] - 1 < γ < arctan[(f - b) / (a - c)] + 1, or even γ = arctan[(f - b) / (a - c)] + 3.

[0174] FIG. 13 is a partial plan view of a pixel island in another display device provided by an embodiment of the present disclosure. As shown in FIG. 13, in each pixel island 120, the strip-shaped pixel light-emitting area 140 includes a plurality of gate lines 142 arranged along the second direction D2, and the first included angle α between the third direction D3 and the second direction D2 also satisfies the following formula: arctan[(a - c) / X * d] - 3 < α < arctan[(a - c) / X * d] + 3,

[0175] where a is the size of the pixel unit in the first direction, d is the distance between two adjacent gate lines in the second direction, c is the size c of the black matrix in the first direction, X is a positive integer greater than or equal to 1, and the units of a, d, and c are micrometers.

[0176] In the display device provided in this example, if X = 1, any virtual straight line extending in the third direction will overlap with one gate line in the strip-shaped pixel light-emitting area. At this time, the integrated brightness of any two virtual straight lines extending in the third direction in the strip-shaped pixel light-emitting area is the same; if X = 2, any virtual straight line extending in the third direction will overlap with two gate lines in the strip-shaped pixel light-emitting area. At this time, the integrated brightness of any two virtual straight lines extending in the third direction in the strip-shaped pixel light-emitting area is the same; if X = 3, any virtual straight line extending in the third direction will overlap with three gate lines in the strip-shaped pixel light-emitting area. At this time, the integrated brightness of any three virtual straight lines extending in the third direction in the strip-shaped pixel light-emitting area is the same, and so on. Thus, if the angle can be freely selected, the first included angle α between the third direction D3 and the second direction D2 can be set to satisfy the above formula, so that the integrated brightness of any two virtual straight lines extending in the third direction in the strip-shaped pixel light-emitting area is always the same, thereby avoiding the generation of brightness differences and thus avoiding the generation of moiré patterns with alternating light and dark.

[0177] It should be noted that if the first angle α satisfying arctan[(a - c) / X*d] - 3 < α < arctan[(a - c) / X*d] + 3 does not satisfy tanα = M / K, the pixel unit columns in the pixel island can be arranged with a dislocation, so that the pixel units in the same pixel unit row are located at the same light splitting position of the same light splitting structure. In addition, in the above formula, 3 is a process error. When the process error is small, the above first angle can also satisfy: arctan[(a - c) / X*d] - 1 < α < arctan[(a - c) / X*d] + 1, or even α = arctan[(a - c) / X*d]. [[ID=^]]

[0178] In some examples, as shown in FIG. 13, in the pixel island 120, the pixel electrode 112 of the (i + 1)-th pixel unit column 132 is displaced a first distance along the second direction relative to the pixel electrode 112 of the i-th pixel unit column 132, so that the boundary line between two adjacent light splitting units can be located on the diagonal of the whole formed by K pixel units arranged along the second direction.

[0179] In some examples, the above first included angle α can also satisfy the following formula: tanα = M / [K + (H / J)], where K is a positive integer greater than or equal to 1, J is a natural number greater than or equal to 2, and H is a natural number greater than or equal to 1 and less than or equal to J. Thus, the display substrate can achieve compensation between pixel islands, avoiding moiré patterns caused by uneven brightness between pixel islands.

[0180] Figure 14 is a partial planar schematic diagram of a pixel island in another display device provided in an embodiment of this disclosure. When the first included angle satisfies the above formula tanα=M / [K+(H / J)], as shown in Figure 14, each pixel island 120 includes N pixel unit columns 132, and each pixel unit column 132 includes M pixel units 110. The pixel electrode 112 of the (i+1)th pixel unit column 132 is displaced by 1 / N pixel pitch relative to the pixel electrode 112 of the ith pixel unit column 132 along the second direction D2. The pixel pitch is the distance between the geometric centers of two adjacent pixel electrodes 112 in the second direction, where i is a positive integer greater than or equal to 1 and less than or equal to N. It should be noted that, since the pixel unit rows in the pixel island are arranged at an angle, for clarity, Figure 14 does not show the complete pixel island; the complete pixel island can be found in Figure 1 or Figure 3.

[0181] In the display device provided in this example, within the pixel island, the pixel electrode of the (i+1)th pixel unit column is displaced relative to the pixel electrode of the ith pixel unit column along a second direction by 1 / N pixel pitch. This displacement of the pixel unit columns allows the line connecting the brightness centers of the N pixel units in each pixel unit row to extend along a third direction, thereby enabling each pixel unit in a pixel unit row to be located at the same position within the same beam-splitting structure, thus achieving better 3D display. For example, as shown in Figure 14, when N=3, the pixel electrode 112 of the second pixel unit column 132 is displaced by 1 / N pixel pitch along the second direction D2 relative to the pixel electrode 112 of the first pixel unit column 132; the pixel electrode 112 of the third pixel unit column 132 is displaced by 1 / N pixel pitch along the second direction D2 relative to the pixel electrode 112 of the second pixel unit column 132; the display substrate can make the line connecting the brightness centers of the N pixel units included in each pixel unit row extend along the third direction by the displacement of the pixel unit columns, so that each pixel unit in the pixel unit row can be located at the same position of the same beam splitting structure, thereby better performing 3D display.

[0182] At least one embodiment of this disclosure also provides an electronic product. Figure 15 is a schematic diagram of an electronic product provided in one embodiment of this disclosure. As shown in Figure 15, the electronic product 500 includes the aforementioned display device 300. Because the electronic product includes the aforementioned display device, it can achieve 3D display. Furthermore, the electronic product has a good 3D display effect in different orientations. On the other hand, the electronic product can also avoid defects such as moiré patterns.

[0183] In some examples, the aforementioned electronic products may include electronic devices with display functions such as televisions, laptops, desktop computers, tablets, navigators, electronic picture frames, and smartphones.

[0184] At least one embodiment of this disclosure also provides a method for manufacturing a display device. Figure 16 is a flowchart of a method for manufacturing a display device according to an embodiment of this disclosure. As shown in Figure 16, the method for manufacturing the display device includes:

[0185] Step S101: Form a display panel, the display panel including a plurality of pixel units arranged in an array along a first direction and a second direction, the plurality of pixel units being divided into a plurality of pixel islands arranged in an array along a third direction and the second direction, the size of each pixel island in the first direction and the size of the pixel island in the second direction being equal, the first direction and the second direction being perpendicular to each other, each pixel island including M rows of pixel units arranged sequentially along the second direction, each row of pixel units including N pixel units arranged along the third direction, where M and N are positive integers greater than or equal to 1;

[0186] Step S102: A beam-splitting component is disposed on the light-emitting side of the display panel. The beam-splitting component includes multiple beam-splitting units, each beam-splitting unit includes P beam-splitting structures, and each beam-splitting structure extends along the third direction, where P is a positive integer greater than or equal to 1. The size of the beam-splitting unit in the second direction is equal to the size of the pixel island in the second direction. The orthographic projection of each beam-splitting unit on the display panel covers Q pixel islands, where Q is a positive integer greater than or equal to 1. In each pixel island, the line connecting the brightness centers of the N pixel units included in each pixel unit row also extends along the third direction. The first angle between the third direction and the second direction is greater than 0 degrees and less than 90 degrees.

[0187] In the manufacturing method of the display device provided in this disclosure embodiment, the size of the beam-splitting unit in the second direction is equal to the size of the pixel island in the second direction. The orthographic projection of each beam-splitting unit on the display panel covers Q pixel islands. Therefore, the light emitted by the pixel units in the Q pixel islands is split by the beam-splitting unit above, causing the left-eye image to enter the user's left eye and the right-eye image to enter the user's right eye, thereby enabling the display device to achieve 3D display. Furthermore, since the line connecting the brightness centers of the N pixel units included in each pixel unit row also extends along the third direction, the pixel units in the same pixel unit row are located at the same beam-splitting position in the same beam-splitting structure, and multiple beam-splitting units can be continuously arranged, thereby enabling the display device to form a continuous light-emitting area. In addition, since each beam-splitting unit extends along the third direction, the display device can achieve 3D display in different orientations. For example, the user can achieve 3D display when using the display device vertically and horizontally.

[0188] On the other hand, since the line connecting the brightness centers of the N pixel units included in each pixel unit row also extends along the third direction D3, when a straight line is displayed on the Q pixel islands covered by the beam splitting unit, the extension direction of the straight line is the same as the extension direction of each beam splitting structure, thereby avoiding defects such as moiré patterns.

[0189] In some examples, the first included angle α satisfies the following formula: tanα = M / K, where K is a positive integer greater than or equal to 1. On one hand, by satisfying the above formula, the line connecting the brightness centers of the N pixel units 110 included in each pixel unit row 131 also extends along the third direction D3. On the other hand, the display device can select the value of K for different sizes, thereby adjusting the extension direction of the beam-splitting structure in the beam-splitting unit while ensuring that the beam-splitting unit can cover M pixel units at different positions, so that display devices of different sizes can have good 3D display effects in different orientations.

[0190] In some examples, the first included angle α mentioned above can also satisfy the following formula: tanα=M / [K+(H / J)], where K is a positive integer greater than or equal to 1, J is a natural number greater than or equal to 2, and H is a natural number greater than or equal to 1 and less than or equal to J.

The planarization layer 103 includes a plurality of vias 103H. The plurality of vias 103H are used for electrical connections between the subsequently formed pixel defining layer and the second source / drain metal layer.

[0242] For example, the material of the planarization layer 103 described above can be an organic insulating material, such as resin. Of course, embodiments of this disclosure include, but are not limited to, this.

[0243] As shown in Figures 34I and 43, the display panel 100 also includes a second sub-common electrode 114B located on the side of the planarization layer 103 away from the substrate 101.

[0244] As shown in Figures 34J and 44, the display panel 100 also includes a first sub-common electrode 114A located on the side of the second sub-common electrode 114B away from the substrate 101, and the first sub-common electrode 114A is electrically connected to the second sub-common electrode 114B.

[0245] For example, the first sub-common electrode 114A is a metal electrode, the second sub-common electrode 114B is a transparent conductive oxide electrode, such as an indium tin oxide (ITO) electrode, and the pixel electrode 112 is also a transparent conductive oxide electrode, such as an indium tin oxide (ITO) electrode.

[0249] For example, the material of the strip pixel electrode 112 can be a transparent conductive oxide, such as indium tin oxide (ITO).

[0250] In the display device provided in the above embodiments, the first included angle α can also satisfy the following formula: tanα=M / [K+(H / J)], where K is a positive integer greater than or equal to 1, J is a natural number greater than or equal to 2, and H is a natural number greater than or equal to 1 and less than or equal to J. Therefore, the display substrate can achieve compensation between pixel islands, avoiding moiré patterns caused by uneven brightness between pixel islands.

[0251] For example, M is set to 16, K to 3, H to 1, and J to 3. Therefore, tanα = 16 / [9 + (1 / 3)], which effectively avoids moiré patterns.

[0252] In the display device provided in the above embodiments, the extension direction of the pixel electrode is the same as the extension direction of the beam splitting structure; and since the design of the first included angle has already taken into account the compensation between pixel islands, there is no need to perform compensation between pixel islands. In addition, the display device provided in this embodiment can achieve grid line moiré compensation by adjusting the width of the black matrix, and perform intra-pixel island compensation by shifting the different pixel unit columns within the pixel island (see the relevant description in Figure 14), which can be referred to the relevant description above, and will not be repeated here.

[0253] Figures 47A-47L are schematic diagrams of multiple structural layers of a display panel in another display device provided in an embodiment of the present disclosure; Figures 48-59 are schematic diagrams of different film layers stacked on a display panel in a display device provided in an embodiment of the present disclosure.

[0254] As shown in Figures 47A and 48, the display panel 100 includes a substrate 101 and a light-shielding layer 190 located on the substrate 101; the light-shielding layer 190 can be used to prevent the driving transistors formed subsequently from being affected by external light.

[0255] For example, the substrate 101 may be made of flexible substrate or rigid substrate; the flexible substrate may be made of polyimide; the rigid substrate may be made of glass, quartz, sapphire, plastic, etc.

[0256] For example, the material of the light-shielding layer 190 includes light-shielding metal.

[0257] As shown in Figures 47B and 49, the display panel 100 includes a semiconductor layer 401 located on the side of the light-shielding layer 190 away from the substrate 101; the semiconductor layer 401 includes an active layer of transistors for pixel driving circuits of a plurality of pixel units 110. It should be noted that an insulating layer is disposed between the semiconductor layer 401 and the light-shielding layer 190, which is not shown for simplicity; furthermore, in the following description, an insulating layer is also disposed between two conductive layers.

[0258] For example, the material of the semiconductor layer 401 mentioned above may include monocrystalline silicon, polycrystalline silicon, or oxide semiconductor materials.

[0259] As shown in Figures 47C and 50, the display panel 100 also includes a gate layer 402 located on the side of the semiconductor layer 401 away from the substrate 101; the gate layer 402 may include the gate lines 142 described above and the gates of the transistors of the pixel driving circuits of the plurality of pixel units 110.

[0260] For example, the material of the gate layer 402 may include copper, molybdenum, aluminum, silver, magnesium, or alloys thereof. The gate layer 402 may be a single-layer structure or a multi-layer composite structure.

[0261] As shown in Figures 47A, 47C, and 50, the light-shielding layer 190 includes a light-shielding structure 145. The orthographic projection of the light-shielding structure on the substrate 101 is connected to the orthographic projection of the gate line 142 on the substrate 101. The dimension z1 of the light-shielding structure 145 in the first direction D1 satisfies the following formula:

[0262] e*tan(α)-3 <z1<e*tan(α)+3,

[0263] The dimension z2 of the light-shielding structure 145 in the second direction D2 satisfies the following formula:

[0264] T*d-(a–c)tan(90-α)-3 <z2<T*d-(a–c)tan(90-α),

[0265] Where, a is the size of the pixel unit 110 in the first direction D1, c is the size of the black matrix 150 in the first direction D1, d is the distance between two adjacent gate lines 142 in the second direction D2, e is the size of the gate line 142 in the second direction D2, T is the maximum number of gate lines 142 that the virtual straight line can overlap, and the units of a, c, d, and e are micrometers.

[0266] In the display device provided in this example, by making the size of the light-shielding structure in the first direction satisfy the formula e*tan(α)-3<z1<e*tan(α)+3, and the size of the light-shielding structure in the second direction satisfy the formula T*d-(a–c)tan(90-α)-3<z2<T*d-(a–c)tan(90-α), when the virtual straight line extending along the third direction D3 moves in the second direction in the strip-shaped pixel light-emitting area, the overlapping area of the virtual straight line with the light-shielding structure and the gate line is always the same, so that the total length of the overlapping parts of any two virtual straight lines extending along the third direction with the gate line and the light-shielding structure in the strip-shaped pixel light-emitting area is equal. Thus, the integral brightness of any two virtual straight lines extending along the third direction in the strip-shaped pixel light-emitting area is always the same, thereby avoiding the generation of brightness differences and thus avoiding the generation of moiré patterns with light and dark intervals.

[0267] It should be noted that in the above formula, 3 is the process error. Therefore, when the process error is small, the size of the light-shielding structure in the first direction can satisfy e*tan(α)-1<z1<e*tan(α)+1, or even z1 = e*tan(α); the size of the light-shielding structure in the second direction can satisfy T*d-(a–c)tan(90-α)-1<z2<T*d-(a–c)tan(90-α)+1, or even z2 = T*d-(a–c)tan(90-α).

It should be noted that, while forming the vias in the second interlayer insulating layer, vias also need to be formed in the first interlayer insulating layer to enable electrical connections between the subsequent second source / drain metal layer and the semiconductor layer.
