Technical Field
[0001] Embodiments of the present disclosure relate to a display device, a method for manufacturing the display device, and an electronic product. Background Art
[0002] With the continuous development of display technology, three-dimensional (3D) display technology has attracted more and more attention. Three-dimensional display technology is a technology that can present stereoscopic images, allowing users to perceive depth, layers and stereoscopic effects on a two-dimensional screen, making the display image three-dimensional and realistic. Three-dimensional display technology can be widely used in many fields such as movies, television, games, medical care, and education. The basic principle of three-dimensional display technology is usually based on the stereoscopic vision characteristics of the human eye, that is, when the human eye observes an object through the left and right eyes, it can perceive the depth, layers and stereoscopic effects of the object due to the slight difference in viewing angle. Therefore, three-dimensional display technology uses various methods to enable the left and right eyes of a person to receive the left eye image and the right eye image with a certain parallax respectively. When the left eye image and the right eye image with a certain parallax are received by the left and right eyes of a person, the image information is superimposed and fused by the brain, and a three-dimensional visual display effect can be constructed.
[0003] On the other hand, we live in a three-dimensional space, and most of human experience comes from the perception of depth information. 3D display can achieve many functions that 2D display does not have because of its depth information. However, looking at most electronic products today, many of them are still at the level of 2D display. This is related to the level of previous image processing technology. With the development of science and technology, image processing technology has made great progress. The current image processing hardware has achieved the characteristics of miniaturization, high efficiency and low heat generation. At the same time, various optical solutions for 3D display have emerged in an endless stream, laying the foundation for the popularization of 3D display technology. Summary of the invention
[0004] The disclosed embodiments provide a display device, a method for manufacturing a display device, and an electronic product. In the display device, the size of the light 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 light splitting unit on the display panel covers Q pixel islands, so that the light emitted by the pixel units in the Q pixel islands is split by the light splitting unit above, so that the left eye image enters the user's left eye, and the right eye image enters the user's right eye, so that the display device can achieve 3D display; and, since the first angle α satisfies tanα=M / K, the pixel units in the same pixel unit row are located at the same light splitting position of the same light splitting structure, and multiple light splitting units can be continuously arranged, so that the display device can form a continuous light-emitting area. In addition, since each light splitting unit extends along the 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 K value for different sizes, thereby adjusting the extension direction of the light splitting structure in the light splitting unit while satisfying that the light splitting unit can cover M pixel units at different positions, so that display devices of different sizes 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, the first angle α between the third direction D3 and the second direction D2 satisfies the formula: tanα=M / K, so when the Q pixel islands covered by the light splitting unit display a straight line, the extension direction of the straight line is the same as the extension direction of each light splitting structure, thereby avoiding the generation of moiré and other defects.

[0088] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.
[0089] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The words "first", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. The words "include" or "comprise" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.
[0090] 3D display technologies include: glasses-type 3D display technology, naked-eye 3D display technology, holographic 3D display technology and volumetric 3D display technology. Glasses-type 3D display technology uses glasses to make the user's left eye receive the left-eye image and the user's right eye receive the right-eye image, thereby synthesizing a 3D image in the user's brain; naked-eye 3D display technology uses only the screen to make the user's left eye receive the left-eye image and the user's right eye receive the right-eye image, thereby synthesizing a 3D image in the user's brain; holographic 3D display technology records and reproduces the amplitude and phase information of the object's light wave to form a realistic 3D stereoscopic image; volumetric 3D display technology uses body scanning or static body imaging and other technologies to directly generate 3D images in space.
[0091] Glasses-type 3D display technology can be divided into color separation 3D, polarized 3D and active shutter 3D. Color difference 3D uses glasses formed by filters of different colors to provide different color images for the left and right eyes, and produces a three-dimensional sense through color differences. However, this method easily causes color cast at the edge of the picture, and the 3D effect is relatively poor. Polarized 3D uses the principle that light has a "polarization direction" to decompose the original image into two groups of pictures with different polarization directions (for example, two groups of pictures of vertically polarized light and horizontally polarized light), and then cooperates with polarized glasses to make the left and right eyes receive the above two groups of pictures with different polarization directions respectively, so as to synthesize a three-dimensional image in the brain. This technology has moderate cost and good image effect, but it has high requirements on the brightness of the display device. Active shutter 3D increases the refresh rate of the picture, divides the image into two frames by frame, forms two groups of pictures corresponding to the left eye and the right eye, and cooperates with active shutter 3D glasses to make the left and right eyes see the corresponding pictures at the right time. This technology can maintain the original resolution of the picture and achieve a true full HD 3D effect, but the glasses are expensive and have certain requirements on the refresh rate of the device. It can be seen that the glasses-type 3D display technology not only requires users to wear glasses, but also has various disadvantages.
[0092] Naked-eye 3D display technology can be divided into light barrier 3D, cylindrical lens 3D and directional light source 3D. Light barrier 3D separates the left and right eye images by setting 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 sequence, creating parallax and forming a three-dimensional sense. Cylindrical lens 3D adds a layer of cylindrical lens in front of the LCD screen so that the image plane of the LCD screen is located on the focal plane of the cylindrical lens. In this way, when both eyes view the LCD screen from different angles, they can see different sub-pixels, thus forming a three-dimensional sense.
[0093] For the cylindrical lens 3D display technology, by forming a continuously luminous display panel and combining it with a cylindrical lens, a better three-dimensional display effect can be achieved. On the other hand, for mobile terminal products, both the horizontal and vertical screen directions are commonly used by users, so the terminal product needs to be able to achieve 3D display at different viewing angles. To this end, the purpose of achieving 3D display at multiple viewing angles can be achieved by forming inclined pixels and prisms. However, in the above design, defects such as rainbow patterns and moiré patterns are prone to occur.
[0094] In this regard, an embodiment of the present disclosure provides a display device, which includes a display panel and a light splitting component; 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 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 the pixel island in the second direction, the first direction and the second direction are perpendicular to each other, each pixel island includes M pixel unit rows arranged in sequence along the second direction, each pixel unit row includes N pixel units arranged along the third direction, and M and N are positive integers greater than or equal to 1; the light splitting component The device is located on the light-emitting side of the display panel and includes a plurality of light-splitting units, each of the light-splitting units includes P light-splitting structures, each of the light-splitting structures extends along the third direction, P is a positive integer greater than or equal to 1, the size of the light-splitting unit in the second direction is equal to the width of the pixel island in the second direction, the orthographic projection of each of the light-splitting units on the display panel covers Q pixel islands, Q is a positive integer greater than or equal to 1, in each of the pixel islands, the line connecting the brightness centers of the N pixel units included in each pixel unit row also extends along the third direction, and a first angle between the third direction and the second direction is greater than 0 degree and less than 90 degrees.
[0095] In the display device provided by the embodiment of the present disclosure, the size of the light 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 light 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 light splitting unit above, so that the left eye image enters the user's left eye and the right eye image enters the user's right eye, so that the display device can realize 3D display; and, since the connecting line of 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 light splitting position of the same light splitting structure, and multiple light splitting units can be arranged continuously, so that the display device can form a continuous light-emitting area. In addition, since each light splitting unit extends along the third direction, the display device can realize 3D display in different orientations. For example, the user can realize 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 the Q pixel islands covered by the spectroscopic unit display a straight line, the extension direction of the straight line is the same as the extension direction of each spectroscopic structure, thereby avoiding the generation of defects such as moiré.
[0096] At least one embodiment of the present disclosure further provides an electronic product, which includes the above-mentioned display device. Since the display device can realize 3D display, the electronic product can also realize 3D display; and the electronic product has a good 3D display effect in different directions. On the other hand, the electronic product can also avoid the generation of defects such as moiré.
[0097] The present disclosure also provides a method for manufacturing a display device, which includes: 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 pixel unit rows arranged in sequence along the second direction, each pixel unit row including N pixel units arranged along the third direction, M and N being positive integers greater than or equal to 1; in the display A spectroscopic component is arranged on the light-emitting side of the panel, and the spectroscopic component includes a plurality of spectroscopic units, each of the spectroscopic units includes P spectroscopic structures, each of the spectroscopic structures extends along the third direction, P is a positive integer greater than or equal to 1, the size of the spectroscopic unit in the second direction is equal to the size of the pixel island in the second direction, and the orthographic projection of each of the spectroscopic units on the display panel covers Q pixel islands, Q is a positive integer greater than or equal to 1, and in each of the pixel islands, a line connecting the brightness centers of the N pixel units included in each pixel unit row also extends along the third direction, and a first angle between the third direction and the second direction is greater than 0 degree and less than 90 degrees.
[0098] In the manufacturing method of the display device provided in the embodiment of the present disclosure, the size of the splitter unit in the second direction is equal to the size of the pixel island in the second direction, and the orthographic projection of each splitter 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 splitter unit above, so that the left eye image enters the user's left eye and the right eye image enters the user's right eye, so that the display device can realize 3D display; and, since the connecting line of 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 splitting position of the same splitter structure, and multiple splitter units can be arranged continuously, so that the display device can form a continuous light-emitting area. In addition, since each splitter unit extends along the third direction, the display device can realize 3D display in different orientations. For example, the user can realize 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 the Q pixel islands covered by the spectroscopic unit display a straight line, the extension direction of the straight line is the same as the extension direction of each spectroscopic structure, thereby avoiding the generation of defects such as moiré.
[0099] Hereinafter, the display device, the method for manufacturing the display device, and the electronic product provided by the embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.
[0100] Figure 1 A schematic plan view of a display device provided by an embodiment of the present disclosure; Figure 2 A partial cross-sectional schematic diagram of a display device provided in one embodiment of the present disclosure.
[0101] like Figure 1 and Figure 2 As shown, the display device 300 includes a display panel 100 and a light 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 the second direction D2, each pixel island 120 includes M pixel unit rows 131 arranged in sequence along the second direction D2, each pixel unit 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, the third direction D3 is different from the first direction D1, and therefore each pixel unit row is tilted. It should be noted that the above-mentioned pixel unit refers to a unit that can be independently controlled for light emission, which can usually be used as a sub-pixel.
[0102] For example, Figure 1As shown, since each pixel island 120 includes M pixel unit rows 131 arranged in sequence along the second direction D2, and each pixel unit row 131 includes N pixel units 110 arranged along the third direction D3; therefore, 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.
[0103] For example, Figure 1 As shown, in order to clearly show the arrangement of the pixel units in the pixel island, each pixel island 120 includes 6 pixel unit rows 131 arranged in sequence along the second direction D2, and each pixel unit row 131 includes 3 pixel units 110 arranged along the third direction D3; that is, the value of M is 6, and the value of N is 3. However, Figure 1 The situation shown is only exemplary, and the embodiments of the present disclosure include but are not limited to this, and M and N can also be set to other values.
[0104] For example, the first direction D1 may be a row direction or a gate line extension direction, and the second direction D2 may be a column direction or a data line extension direction. In addition, when the display device is approximately rectangular, the first direction D1 and the second direction D2 may also be the length direction and the width direction of the display device. Of course, the embodiments of the present disclosure include but are not limited to this, and the first direction and the second direction may be set according to the situation, as long as the first direction and the second direction are perpendicular to each other.
[0105] like Figure 1 and Figure 2 As shown, the light splitting component 200 is located on the light emitting side of the display panel 100, and includes a plurality of light splitting units 210, each light splitting unit 210 includes P light splitting structures 220, each light splitting structure 200 extends along the third direction D3, P is a positive integer greater than or equal to 1; that is, the extension direction of each light splitting structure 200 is consistent with the arrangement direction of the pixel unit row 131. The size of the light splitting unit 210 in the second direction D2 is equal to the size of the pixel island 120 in the second direction D2, and the orthographic projection of each light splitting unit 210 on the display panel 100 covers Q of the pixel islands, Q is a positive integer greater than or equal to 1.
[0106] For example, Figure 2 As shown, each light splitting unit 210 includes one light splitting structure 220, that is, P = 1. However, the embodiments of the present disclosure include but are not limited to this, and each light splitting unit 210 may also include 2, 3, 4, 5, or 6 light splitting structures 220, and the value of P may be set as required.
[0107] like Figure 1 and Figure 2As shown, 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.
[0108] In the display device provided by the embodiment of the present disclosure, the size of the light 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 light 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 light splitting unit above, so that the left eye image enters the user's left eye and the right eye image enters the user's right eye, so that the display device can realize 3D display; and, since the connecting line of 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 light splitting position of the same light splitting structure, and multiple light splitting units can be arranged continuously, so that the display device can form a continuous light-emitting area. In addition, since each light splitting unit extends along the third direction, the display device can realize 3D display in different orientations. For example, the user can realize 3D display when using the display device vertically and horizontally.
[0109] 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 the Q pixel islands covered by the spectroscopic unit display a straight line, the extension direction of the straight line is the same as the extension direction of each spectroscopic structure, thereby avoiding the generation of defects such as moiré.
[0110] In some examples, the first angle between the third direction D3 and the second direction D2 is greater than 0 degrees and less than 90 degrees, and the first 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 K value for different sizes, so as to adjust the extension direction of the light splitting structure in the light splitting unit while satisfying that the light splitting unit can cover M pixel units at different positions, so that display devices of different sizes have good 3D display effects in different orientations.
[0111] It is worth noting that in the display device provided in the embodiment of the present disclosure, 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. In other words, the display device can switch between a 2D display mode and a 3D display mode. When the display device is used for 2D display, its resolution is high. In some examples, the above-mentioned light splitting structure 220 may be a cylindrical lens, and each light splitting unit 210 may include a plurality of cylindrical lenses arranged in parallel.
[0112] For example, the above-mentioned cylindrical lens is a liquid crystal lens. In specific implementation, when the cylindrical lens is a liquid crystal lens that can be zoomed, it is possible to achieve different curvature radii of the cylindrical lens at different viewing angles, and relatively small adjacent viewpoint crosstalk that does not change significantly with the fluctuation of the curvature radius, as well as a larger left-right eye zero crosstalk viewing range. Of course, the embodiments of the present disclosure include but are not limited to this, and the light splitting structure can also be a geometric lens, a diffraction lens, a liquid lens, and other structural devices that can realize the control of the light emitting direction of the sub-pixel.
[0113] In some examples, such as Figure 1 As shown, the size of each pixel island 120 in the first direction D1 ranges from 60 microns to 180 microns. 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 microns to 150 microns, such as 106 microns, 136 microns, 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 microns to 180 microns, such as 152 microns, 175 microns, 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 microns to 90 microns, such as 60 microns, 80 microns, etc.
[0114] In some examples, such as Figure 1 As shown, the size of each pixel island 120 in the second direction D2 is substantially equal to the size of each pixel island 120 in the first direction D1 , and thus the size of each pixel island 120 in the second direction D2 also ranges from 60 micrometers to 180 micrometers.
[0115] In some examples, such as Figure 1 As shown, in each pixel island 120, the size of each pixel unit 110 in the first direction D1 ranges from 25 microns to 40 microns, such as 30 microns and 35 microns; the size of each pixel unit 110 in the second direction D2 ranges from 5 microns to 10 microns, such as 8 microns. Figure 1 and Figure 2 As shown, each pixel unit 110 includes a strip pixel electrode 112 extending along the fourth direction D4, and 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 extension directions of the N strip pixel electrodes 112 of the N pixel units 110 included in each pixel unit row 131 are the same, and the second angle between the fourth direction D4 and the second direction D2 is greater than 0 degrees and less than 90 degrees.
[0116] In the display device provided in this example, since the connecting line of the centers of the N strip pixel electrodes of the N pixel units included in each pixel unit row also extends along the 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 overlapped with the strip pixel electrode in the same row by translation, thereby further avoiding the generation of moiré and other defects. It should be noted that the pixel electrode is one of the main electrodes for 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.
[0117] In some examples, such as Figure 1 and Figure 2 As shown, 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 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, and the black matrix 150 is located on both sides of the strip pixel light-emitting area 140 in the first direction D1.
[0118] 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 provided between the effective light-emitting areas of the adjacent pixel units in the second direction, the pixel density of the display device is greatly improved, and thus it is suitable for 3D display. It should be noted that, although no black matrix is provided between the adjacent pixel units in the second direction, a gate line extending along the first direction is provided in the strip-shaped pixel light-emitting area.
[0119] In some examples, since no black matrix is provided between the effective light-emitting areas of the adjacent pixel units in the second direction, the number of pixel units arranged along the second direction in one pixel island may be 11, 12, 13, or 16, that is, the value of M may be 11, 13, or 16. It should be noted that in order to more clearly illustrate the pixel electrode, Figure 1 The number of pixel unit rows in a pixel island is relatively small, but the embodiments of the present disclosure include but are not limited to this. The number of pixel unit rows in a pixel island may be 11, 12, 13, 16, or even more, thereby improving the pixel density and being suitable for 3D display.
[0120] For example, when the value of 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).
[0121] For example, when the value of 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).
[0122] For example, when the value of 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).
[0123] For example, when the value of 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).
[0124] In some examples, such as Figure 1 As shown, in a pixel island 120, each pixel unit row 131 includes three pixel units 110 arranged along the third direction D3; that is, the value of N is 3. For example, the three pixel units 110 included in each pixel unit row 131 may be three pixel units 110 emitting light of different colors, 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 the present disclosure include but are not limited to this, and the value of N may also be other suitable values.
[0125] In some examples, in the formula tanα=M / K satisfied by the first angle α, the value of K is a positive integer greater than or equal to 1. The display device can select the K value for different sizes, so as to adjust the extension direction of the light splitting structure in the light splitting unit while satisfying that the light splitting unit can cover M pixel units at different positions, so that display devices of different sizes have good 3D display effects in different orientations.
[0126] In some examples, such as Figure 1As shown, the fourth direction D4 is the same as the third direction D3, and the first angle and the second angle are the same. That is, the extension direction of the pixel unit row in each pixel island, the extension direction of the light splitting structure and the extension direction of the strip pixel electrode in each pixel unit are the same. Thus, the display device can further avoid the generation of moiré. Of course, the embodiments of the present disclosure include but are not limited to this, and the fourth direction and the third direction may also be different.
[0127] In some examples, such as Figure 2 As shown, 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 above-mentioned pixel electrode 112 can be arranged on the array substrate 100A, and the above-mentioned black matrix 150 can be arranged on the array substrate 100A or the opposing substrate 100B.
[0128] Figure 3 FIG. 1 is a plan view of another display device provided by an embodiment of the present disclosure. Figure 3 As shown, the display device 300 includes a display panel 100 and a light 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 the second direction D2, each pixel island 120 includes M pixel unit rows 131 arranged in sequence along the second direction D2, each pixel unit 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, the third direction D3 is different from the first direction D1, and therefore each pixel unit row is tilted. It should be noted that the above-mentioned pixel unit refers to a unit that can be independently controlled for light emission, which can usually be used as a sub-pixel.
[0129] like Figure 3 As shown, the light splitting component 200 is located on the light emitting side of the display panel 100, and includes a plurality of light splitting units 210, each light splitting unit 210 includes P light splitting structures 220, each light splitting structure 200 extends along the third direction D3, P is a positive integer greater than or equal to 1; that is, the extension direction of each light splitting structure 200 is consistent with the arrangement direction of the pixel unit row 131. The size of the light splitting unit 210 in the second direction D2 is equal to the size of the pixel island 120 in the second direction D2, and the orthographic projection of each light splitting unit 210 on the display panel 100 covers Q of the pixel islands, Q is a positive integer greater than or equal to 1.
[0130] like Figure 3As shown, 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, and the first angle between the third direction D3 and the second direction D2 is greater than 0 degree and less than 90 degrees.
[0131] like Figure 3 As shown, each pixel unit 110 includes a strip pixel electrode 112 extending along the fourth direction D4, and 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 extension directions of the N strip pixel electrodes 112 of the N pixel units 110 included in each pixel unit row 131 are the same, and the second angle between the fourth direction D4 and the second direction D2 is greater than 0 degrees and less than 90 degrees.
[0132] like Figure 3 As shown, the fourth direction D4 is different from the third direction D3.
[0133] In the display device provided by the embodiment of the present disclosure, in the display device provided by the embodiment of the present disclosure, the size of the 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 splitting unit on the display panel covers Q pixel islands, so the light emitted by the pixel units in the Q pixel islands is split by the splitting unit above so that the left eye image enters the user's left eye and the right eye image enters the user's right eye, so that the display device can realize 3D display; and, since the connecting line of 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 splitting position of the same splitting structure, and multiple splitting units can be arranged continuously, so that the display device can form a continuous light-emitting area. In addition, since each splitting unit extends along the third direction, the display device can realize 3D display in different orientations. For example, the user can realize 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 the Q pixel islands covered by the spectroscopic unit display a straight line, the extension direction of the straight line is the same as the extension direction of each spectroscopic structure, thereby avoiding the generation of defects such as moiré.
[0134] 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 the Q pixel islands covered by the spectroscopic unit display a straight line, the extension direction of the straight line is the same as the extension direction of each spectroscopic structure, thereby avoiding the generation of defects such as moiré patterns.
[0135] In some examples, the first angle between the third direction D3 and the second direction D2 is greater than 0 degrees and less than 90 degrees, and the first 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 K value for different sizes, so as to adjust the extension direction of the light splitting structure in the light splitting unit while satisfying that the light splitting unit can cover M pixel units at different positions, so that display devices of different sizes have good 3D display effects in different orientations.
[0136] For example, Figure 3 As shown, in order to clearly show the arrangement of the pixel units in the pixel island, each pixel island 120 includes 5 pixel unit rows 131 arranged in sequence along the second direction D2, and each pixel unit row 131 includes 3 pixel units 110 arranged along the third direction D3; that is, the value of M is 5, and the value of N is 3. However, Figure 1 The situation shown is only exemplary, and the embodiments of the present disclosure include but are not limited to this, and M and N can also be set to other values.
[0137] During the study, the inventor of the present application also noticed that: since there are also grid lines in the strip pixel luminous area, the grid lines have a certain blocking effect on light. At this time, if the integrated brightness of the virtual straight line extending along the third direction in the strip pixel luminous area is different, it will also produce moiré patterns of light and dark. In this regard, the embodiment of the present disclosure also makes a targeted design for the above problem to avoid moiré patterns caused by the grid lines. It should be noted that for the sake of clarity, Figure 1 The grid lines are not shown. Figure 1 The position of the middle grid line can be referenced Figure 4 .
[0138] Figure 4 FIG. 1 is a partial plan view of a pixel island in a display device provided by an embodiment of the present disclosure. Figure 4 As shown, in each pixel island 120, the strip pixel light emitting area 140 includes a plurality of gate lines 142 arranged along the second direction D2, and the dimension c of the black matrix 150 in the first direction D1 satisfies the following formula:
[0139] [a-tan(90-α) / X*d]-3 <c<[a-tan(90-α) / X*d]+3,
[0140] Among them, 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 centerlines of two adjacent gate lines.
[0141] 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 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, 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 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.
[0142] 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.
[0143] It should be noted that Figure 3 The settings and relative positional relationships of the pixel islands, strip-shaped light-emitting areas, and black matrices in the shown embodiments can be the same as those in Figure 1 or Figure 3 the shown embodiments. Therefore, the settings of the above pixel islands, strip-shaped pixel light-emitting areas, and black matrices can be referred to in Figure 1 or Figure 3 the relevant descriptions, which will not be elaborated here.
[0144] In some examples, when [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.
[0145] In some examples, as Figure 4 shown, two pixel units 110 adjacent 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.
[0146] In some examples, as Figure 4 shown, the gate lines 142 in each pixel light-emitting region 140 extend along the first direction D1; that is, the display device provided in this example does not change the extension direction of the gate lines.
[0147] Figure 5A is a partial plan view of a pixel island in another display device provided by an embodiment of the present disclosure; Figure 5B is a partial plan view of a pixel island in another display device provided by an embodiment of the present disclosure. As Figure 5A and Figure 5B shown, 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:
[0148] arctan[(|X*d - (a - c)tan(90 - α)|) / (a - c)] - 3 < β < arctan[(|X*d - (a - c)tan(90 - α)|) / (a - c)] + 3,
[0149] 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.
[0150] In the display device provided in this example, by changing the extending direction of the gate lines in the strip-shaped pixel light-emitting region, 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 region. At this time, the integrated brightness of any two virtual straight lines extending along the third direction in the strip-shaped pixel light-emitting region 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 region. At this time, the integrated brightness of any two virtual straight lines extending along the third direction in the strip-shaped pixel light-emitting region 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 region. At this time, the integrated brightness of any two virtual straight lines extending along the third direction in the strip-shaped pixel light-emitting region is the same, and so on. Thus, since 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 region is always the same, thereby avoiding the generation of brightness differences and thus avoiding the generation of moiré patterns with alternating light and dark. In addition, since the display device provided in this example does not need to change the width of the black matrix, it is possible to avoid the generation of moiré patterns with alternating light and dark while ensuring a relatively high aperture ratio.
[0151] 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 region extend along the fifth direction, while the gate lines in the region where the black matrix is located can extend in other directions. In addition, in the formula satisfied by the second included angle β above, 3 is the process error, and its unit is degree. Therefore, in the case of a relatively small process error, 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)].
[0152] For example, as Figure 5AAs shown, X=1, any virtual straight line extending along the third direction will overlap with a gate line 142 in the strip 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 pixel light-emitting area 140 is the same, thereby avoiding brightness differences and thus avoiding the generation of moiré patterns of alternating light and dark.
[0153] For example, Figure 5B As shown, X=2, any virtual straight line extending along the third direction will overlap with two gate lines 142 in the strip 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 pixel light-emitting area 140 is the same, thereby avoiding brightness differences and thus avoiding the generation of moiré patterns of alternating light and dark.
[0154] Figure 6 FIG. 1 is a partial plan view of another pixel island in a display device provided by an embodiment of the present disclosure. Figure 6 As shown, in each pixel island 120, the strip pixel light-emitting area 140 includes a plurality of gate lines 142 arranged along the second direction, and each strip pixel light-emitting area 140 also includes a shading structure 145, which is located between two adjacent gate lines 142, and the total length of any two virtual straight lines extending along the third direction D3 and the overlapping portion of the gate lines 142 and the shading structure 145 in the strip pixel light-emitting area 140 is equal. Thus, by adding a shading structure between adjacent gate lines, the integrated brightness of any two virtual straight lines extending along the third direction in the strip pixel light-emitting area is always the same, thereby avoiding the generation of brightness differences, thereby avoiding the generation of moiré patterns of light and dark alternations. In addition, since the display device provided in this example does not need to change the width of the black matrix, it is possible to avoid the generation of moiré patterns of light and dark alternations while ensuring a high aperture ratio.
[0155] In some examples, such as Figure 6 As shown, the display panel 100 includes a base substrate 101, an orthographic projection of a light shielding structure 145 on the base substrate 101 is connected to an orthographic projection of a black matrix 150 on the base substrate 101, and a dimension z1 of the light shielding structure 145 in a first direction D1 satisfies the following formula:
[0156] 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:
[0158] T*d-(a–c)tan(90-α)-3 <z2<T*d-(a–c)tan(90-α)+3,
[0159] Wherein, 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.
[0160] 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 thus avoiding the generation of moiré patterns with light and dark intervals.
[0161] 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).
[0162] For example, as Figure 6 shown, the light-shielding structure 145 and the black matrix 150 can be provided on 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. 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.
[0163] Figure 7 This is a partial plan view of a pixel island in another display device provided by an embodiment of the present disclosure. Different from Figure 6 the integral light-shielding structure 145 in Figure 7As shown, the light shielding structure 145 includes a plurality of sub-light shielding structures 1450, and the size of each sub-light shielding structure 1450 in the first direction D1 is the same as the size of the light shielding structure 145 in the first direction D1, and the size of the light shielding structure 145 in the second direction D2 is equal to the sum of the sizes of the plurality of 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 where the virtual straight line overlaps with the light shielding structure and the gate line is always the same, so that the total length of the portion where any two virtual straight lines extending along the third direction overlap with the gate line and the light shielding structure in the strip-shaped pixel light-emitting area is equal. Therefore, 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, thereby avoiding the generation of moiré patterns of light and dark alternations.
[0164] For example, Figure 7 As shown, the light shielding structure 145 may include two sub-light shielding structures 1450, and the 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.
[0165] In some examples, such as Figure 7 As shown, the shading structure 145 and the black matrix 150 can be arranged in the same layer. For example, the shading 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 the present disclosure include but are not limited to this, and the shading structure can also be formed in other film layers, as long as the orthographic projection of the shading structure on the substrate is connected to the orthographic projection of the black matrix on the substrate.
[0166] Figure 8 A partial plan view of a pixel island in another display device provided by an embodiment of the present disclosure. Figure 7 The shading structure shown is different from that shown in FIG. Figure 8 As shown, the display panel 100 includes a base substrate 101, an orthographic projection of a light shielding structure 145 on the base substrate 101 is connected to an orthographic projection of a gate line 142 on the base substrate 101, and a dimension z1 of the light shielding structure 145 in a first direction D1 satisfies the following formula:
[0167] e*tan(α)-3 <z1<e*tan(α)+3,
[0168] The dimension z2 of the light shielding structure 145 in the second direction D2 satisfies the following formula:
[0169] T*d - (a – c)tan(90 - α) - 3 < z2 < T*d - (a – c)tan(90 - α),
[0170] Wherein, 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.
[0171] 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 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 light and dark intervals.
[0172] 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).
[0173] In some examples, as Figure 8 shown, the light-shielding structure 145 and the gate line 142 are arranged 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, 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 gate line on the substrate.
[0174] Fig. 9 This is a partial plan view of a pixel island in another display device provided by an embodiment of the present disclosure. Different from the Figure 8 shown light-shielding structure, as Fig. 9As shown, the display panel 100 further includes a light shielding layer 190, which is located on the base substrate 101; in this case, the light shielding structure 145 is located on the light shielding layer 190. In other words, the light shielding layer is used to form the above-mentioned light shielding structure. It should be noted that pixel driving circuits are arranged on both sides of the strip-shaped pixel light-emitting area, and a light shielding layer is usually arranged between the pixel driving circuit and the base substrate to prevent external light from causing adverse effects on the pixel driving circuit.
[0175] During the study, the inventors of the present application also noticed that although there is no black matrix in the strip pixel light-emitting area, since the pixel electrodes in the strip 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 pixel light-emitting area. This regular uneven brightness is easily amplified by the spectroscopic structure to form moiré patterns.
[0176] For example, Fig.10 The schematic diagram is a principle diagram of how a display device generates moiré patterns. Fig.10 As shown, the light-splitting structure 220 covers a plurality of pixel electrodes 112; since the pixel electrodes 112 in the strip pixel light-emitting area 140 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 pixel light-emitting area 140, and this regular brightness unevenness is easily amplified by the light-splitting structure 220 to form moiré patterns.
[0177] Fig.11 FIG. 1 is a plan view of another display device provided by an embodiment of the present disclosure. Fig.11 As shown, 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 the third direction D3 form a pixel group 180, and the pixel group 180 includes Y*N pixel unit columns 132; in the pixel group 180, the pixel electrodes 112 of the N pixel unit columns 132 in the i+1th pixel island 120 are shifted 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 i-th pixel island 120, and 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.
[0178] In the display device provided in this example, the pixel group can be regarded as a repeating unit, and the Q pixel islands covered by the light-splitting unit can form Q / Y repeating units; in each pixel group, the pixel electrodes of the N pixel unit columns in the i+1th 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 i-th pixel island, and when the virtual straight line extending along the third direction passes through each pixel island, the overlap between the virtual straight line and the pixel electrode in the pixel island is different, thereby avoiding the situation where one virtual straight line overlaps with the N pixel electrodes in the pixel island, while the other virtual straight line overlaps with the 0 pixel electrodes in the pixel island. As described 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-mentioned setting, the display device can reduce the brightness difference between any two virtual straight lines extending along the third direction, so that the light output brightness at different positions of the light-splitting structure is more uniform, thereby preventing regular brightness unevenness and thus avoiding the generation of moiré.
[0179] For example, Fig.11 As shown, 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 a virtual straight line extending along the third direction passes through 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.
[0180] In some examples, the value of Y may be 3, 4 or 5. Of course, the embodiments of the present disclosure include but are not limited to this.
[0181] Fig. 12A A partial plan view of a pixel island in another display device provided by an embodiment of the present disclosure; Fig. 12B FIG. 1 is a schematic diagram of an extension direction of a pixel electrode in a display device provided by an embodiment of the present disclosure. Fig. 12A and Fig. 12B As shown, each pixel island includes M pixel unit rows arranged in sequence along the second direction D2, and each pixel unit row includes N pixel units 110 arranged along the third direction D3; each splitting structure 200 extends along the third direction D3, and each pixel unit 110 includes a strip pixel electrode 112 extending along the fourth direction D4.
[0182] 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:
[0183] arctan[(f - b) / (a - c)] - 3 < γ < arctan[(f - b) / (a - c)] + 3,
[0184] 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.
[0185] 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 moiré patterns.
[0186] 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, and even γ = arctan[(f - b) / (a - c)] + 3.
[0187] Fig.13 FIG. is a partial plan view of a pixel island in another display device provided by an embodiment of the present disclosure. As Fig.13 shown, 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:
[0188] arctan[(a - c) / X*d] - 3 < α < arctan[(a - c) / X*d] + 3,
[0189] 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.
[0190] In the display device provided in this example, if X = 1, any virtual straight line extending in the third direction will overlap with a 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 light and dark intervals.
[0191] It should be noted that if the first angle α that satisfies 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 misaligned, 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 the 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].
[0192] In some examples, such as Fig.13 shown, in the pixel island 120, the pixel electrode 112 of the (i + 1)-th pixel unit column 132 is displaced by a first distance in the second direction relative to the pixel electrode 112 of the i-th pixel unit column 132, so that the boundary line between adjacent two light splitting units can be located on the diagonal of the whole formed by K pixel units arranged in the second direction.
[0193] 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 and avoid moiré patterns caused by uneven brightness between pixel islands.
[0194] Fig.14FIG. 1 is a partial plan view of another pixel island in a display device provided by an embodiment of the present disclosure. When the first angle satisfies the above formula tanα=M / [K+(H / J)], Fig.14 As shown, each pixel island 120 includes N pixel unit columns 132, each pixel unit column 132 includes M pixel units 110, and the pixel electrode 112 of the i+1th pixel unit column 132 is shifted by 1 / N pixel pitch along the second direction D2 relative to the pixel electrode 112 of the i-th pixel unit column 132, and the pixel pitch is the distance between the geometric centers of two adjacent pixel electrodes 112 in the second direction, and 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 obliquely, for clarity, Fig.14 The complete pixel island is not shown. The complete pixel island can be found in Figure 1 or Figure 3 .
[0195] In the display device provided in this example, in the pixel island, the pixel electrode of the i+1th pixel unit column is displaced by 1 / N pixel pitch along the second direction relative to the pixel electrode of the ith pixel unit column. The display substrate can make the connection line of the brightness centers of the N pixel units included in each pixel unit row also extend along the third direction through the displacement of the pixel unit column, so that each pixel unit in the pixel unit row can be located at the same position of the same light splitting structure, so as to better perform 3D display. For example, Fig.14 As shown, 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 connection line of the brightness centers of the N pixel units included in each pixel unit row extend along the third direction through the displacement of the pixel unit column, so that each pixel unit in the pixel unit row can be located at the same position of the same splitting structure, thereby better performing 3D display.
[0196] At least one embodiment of the present disclosure also provides an electronic product. Fig.15 Schematic diagram of an electronic product provided by an embodiment of the present disclosure. Fig.15 As shown, the electronic product 500 includes the above-mentioned display device 300. Since the electronic product includes the above-mentioned display device, the electronic product can realize 3D display. Moreover, the electronic product has a good 3D display effect in different directions. On the other hand, the electronic product can also avoid the generation of defects such as moiré.
[0197] In some examples, the electronic products mentioned above may be electronic devices with display functions, such as televisions, laptop computers, desktop computers, tablet computers, navigators, electronic picture frames, and smart phones.
[0198] At least one embodiment of the present disclosure further provides a method for manufacturing a display device. Fig.16 Flow chart of a method for manufacturing a display device provided by an embodiment of the present disclosure. Fig.16 As shown, the manufacturing method of the display device includes:
[0199] Step S101: forming a display panel, the display panel comprising 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 of the pixel islands comprising M pixel unit rows arranged in sequence along the second direction, each of the pixel unit rows comprising N pixel units arranged along the third direction, and M and N being positive integers greater than or equal to 1;
[0200] Step S102: a light-splitting component is arranged on the light-emitting side of the display panel, the light-splitting component includes a plurality of light-splitting units, each of the light-splitting units includes P light-splitting structures, each of the light-splitting structures extends along the third direction, P is a positive integer greater than or equal to 1; the size of the light-splitting unit in the second direction is equal to the size of the pixel island in the second direction, the orthographic projection of each of the light-splitting units on the display panel covers Q pixel islands, Q is a positive integer greater than or equal to 1, in each of the pixel islands, a 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 a first angle between the third direction and the second direction is greater than 0 degrees and less than 90 degrees,
[0201] In the manufacturing method of the display device provided by the embodiment of the present disclosure, in the display device provided by the embodiment of the present disclosure, the size of the 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 splitting unit on the display panel covers Q pixel islands, so the light emitted by the pixel units in the Q pixel islands is split by the splitting unit above so that the left eye image enters the user's left eye and the right eye image enters the user's right eye, so that the display device can realize 3D display; and, since the connecting line of 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 splitting position of the same splitting structure, and multiple splitting units can be arranged continuously, so that the display device can form a continuous light-emitting area. In addition, since each splitting unit extends along the third direction, the display device can realize 3D display in different orientations. For example, the user can realize 3D display when using the display device vertically and horizontally.
[0202] 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 the Q pixel islands covered by the spectroscopic unit display a straight line, the extension direction of the straight line is the same as the extension direction of each spectroscopic structure, thereby avoiding the generation of defects such as moiré.
[0203] In some examples, the first 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 K value for different sizes, so as to adjust the extension direction of the light splitting structure in the light splitting unit while satisfying that the light splitting unit can cover M pixel units at different positions, so that display devices of different sizes have better 3D display effects in different orientations.
[0204] In some examples, the first angle α may 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.

[0256] For example, the material of the planar layer 103 may be an organic insulating material, such as resin. Of course, the embodiments of the present disclosure include but are not limited to this.
[0257] like Fig.34I and Fig.43 As shown, the display panel 100 further includes a second sub-common electrode 114B located on a side of the planar layer 103 away from the base substrate 101 .
[0258] like Fig.34J and Fig.44 As shown, the display panel 100 further includes a first sub-common electrode 114A located on a side of the second sub-common electrode 114B away from the base substrate 101 , and the first sub-common electrode 114A is electrically connected to the second sub-common electrode 114B.

[0268] like Fig.47A and Fig.48 As shown, the display panel 100 includes a base substrate 101 and a light shielding layer 190 located on the base substrate 101; the light shielding layer 190 can be used to prevent a driving transistor formed subsequently from being affected by external light.
[0269] For example, the material of the substrate 101 includes a flexible substrate and a rigid substrate; the material of the flexible substrate may include polyimide; the material of the rigid substrate may include glass, quartz, sapphire, plastic, etc.
[0270] For example, the material of the light shielding layer 190 includes a light shielding metal.
[0271] like Fig.47B and Fig.49 As shown, the display panel 100 includes a semiconductor layer 401 located on a side of the light shielding layer 190 away from the base substrate 101; the semiconductor layer 401 includes an active layer of transistors of a pixel driving circuit of a plurality of pixel units 110. It should be noted that an insulating layer is provided between the semiconductor layer 401 and the light shielding layer 190, but the insulating layer is not shown for simplicity; in addition, in the subsequent description, an insulating layer is also provided between the two conductive layers.
[0272] For example, the material of the semiconductor layer 401 may include single crystal silicon, polycrystalline silicon or oxide semiconductor material.
[0273] like Fig.47C and Fig.50 As shown, the display panel 100 further includes a gate layer 402 located on a side of the semiconductor layer 401 away from the base substrate 101 ; the gate layer 402 may include the above-mentioned gate line 142 and gates of transistors of the pixel driving circuit of the plurality of pixel units 110 .
[0274] For example, the material of the gate layer 402 may include copper, molybdenum, aluminum, silver, magnesium, or their alloys. The gate layer 402 may adopt a single-layer structure or a multi-layer composite structure.
[0275] As Fig.47A , Fig.47C and Fig.50 shown, 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:
[0276] e * tan(α) - 3 < z1 < e * tan(α) + 3,
[0277] The dimension z2 of the light-shielding structure 145 in the second direction D2 satisfies the following formula:
[0278] T * d - (a – c)tan(90 - α) - 3 < z2 < T * d - (a – c)tan(90 - α),
[0279] where a is the dimension of the pixel unit 110 in the first direction D1, c is the dimension 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 dimension of the gate line 142 in the second direction D2, T is the maximum number of gate lines 142 that a virtual straight line can overlap, and the units of a, c, d, and e are micrometers.
[0280] In the display device provided in this example, by making the dimension of the light-shielding structure in the first direction satisfy the formula e * tan(α) - 3 < z1 < e * tan(α) + 3, and the dimension of the light-shielding structure in the second direction satisfy 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 lines 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 alternating light and dark.
[0281] It should be noted that in the above formula, 3 is the process error. Therefore, when the process error is small, the dimension 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 dimension 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).
