[0031] The following further describes in detail the specific embodiments of the present disclosure in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present disclosure, but are not used to limit the scope of the present disclosure. It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments can be arbitrarily combined with each other.

[0032] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should have the ordinary meanings understood by those with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar terms used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as "including" or "comprising" 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. Words such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0033] 3D displays have gradually become popular in recent years. The main principle of 3D display technology is to enable the viewer's left and right eyes to receive different images respectively. The two images of the left and right eyes are analyzed and overlapped by the human brain, so that the viewer can perceive the sense of hierarchy of the image screen and thus generate a sense of three-dimensionality. Among them, the naked-eye 3D display technology is a research hotspot of 3D display technology.

[0034] The naked-eye 3D display technology mainly includes holographic 3D display technology, volumetric 3D display technology, autostereoscopic 3D display technology, etc. Among them, the autostereoscopic 3D display technology has always been considered to be the naked-eye 3D display technology that may be commercialized the fastest because it can obtain dynamic, color, and large viewing angle three-dimensional display effects. The autostereoscopic 3D display technology includes naked-eye 3D display technology based on geometric optics, such as lenticular lens array technology, parallax barrier technology, microlens array technology, etc. Such technologies are mainly based on the principles of linear propagation, reflection, refraction, etc. of light. Through the design of the structure, the outgoing direction of each pixel in the display screen is changed, and the images of each viewing angle are projected onto different viewing point positions, so that the left and right eyes of a person can view different viewing angle images and form a stereoscopic visual sense.

[0035] Currently, naked-eye 3D displays generally adopt the Super Multi View technology, that is, multiple viewpoints are set so that users can view the 3D display screen at multiple positions. Currently, among the light field display exhibits at major exhibitions, large-size naked-eye 3D display exhibits are basically based on Liquid Crystal Display (LCD) technology, and small-size naked-eye 3D display exhibits are usually based on either LCD or Organic Light-Emitting Diode (OLED) display technology. There are basically no light field display exhibits based on Mini Light Emitting Diode (MiniLED) display technology or Micro Light Emitting Diode (Micro LED) display technology. Large-size Mini or Micro LED display panels are generally formed by splicing. A large-size display panel requires a large viewing angle. However, the current capabilities of 3D devices are not sufficient to achieve large viewing angle displays.

[0036] An embodiment of the present disclosure provides a display component, including a display panel, a dynamic grating layer, and a lens structure layer. Among them, the display panel includes multiple pixel islands, at least one pixel island includes multiple pixel units, and the multiple pixel islands include a first pixel island and a second pixel island; the dynamic grating layer is disposed on one side of the light-emitting surface of the display panel and includes multiple grating periods. Each grating period includes an opening area in the middle and light-shielding areas on both sides of the opening area. The opening area is configured to cause the light emitted by the pixel units of the first pixel island to form the first viewpoint to the m-th viewpoint, and the light emitted by the pixel units of the second pixel island to form the (m + 1)-th viewpoint to the n-th viewpoint. m is a natural number greater than 1, and n is a natural number greater than (m + 1); the lens structure layer is disposed on the side of the dynamic grating layer away from the display panel and includes multiple lenses.

[0037] For the display component provided by the embodiment of the present disclosure, the deflection angles of the light beams emitted by the first pixel island and the second pixel island are controlled by the dynamic grating layer, so that the light beams emitted by the first pixel island form the first viewpoint to the m-th viewpoint, and the light beams emitted by the second pixel island form the (m + 1)-th viewpoint to the n-th viewpoint. The first viewpoint to the m-th viewpoint and the (m + 1)-th viewpoint to the n-th viewpoint are jointly spliced to form a large viewing angle light field display, and the light is collimated by the lens structure layer, reducing the crosstalk between the light beams, and can meet the requirements of large viewing angle light field display and multi-person viewing of large-size display panels.

[0038] Figure 1 It is a schematic three-dimensional structure diagram of a display component provided according to an exemplary embodiment of the present disclosure. Figure 2 It is a schematic plan view of a display component provided according to an exemplary embodiment of the present disclosure. AsFigure 1 and Figure 2 As shown in and

[0039] , an exemplary embodiment of the present disclosure provides a display component, including a display panel 10, a dynamic grating layer 20, and a lens structure layer 30.

[0039] Among them, the display panel 10 includes a plurality of pixel islands 101. At least one pixel island 101 includes a plurality of pixel units P arranged continuously along a set direction. The plurality of pixel islands 101 include a first pixel island 1011 and a second pixel island 1012.

[0040] The dynamic grating layer 20 is disposed on one side of the light-emitting surface of the display panel 10 and includes a plurality of grating periods T. Each grating period T includes an opening area 201 in the middle and light-shielding areas 202 on both sides of the opening area 201. The opening area 201 is configured to make the light emitted by the pixel units P of the first pixel island 1011 form the first view point to the m-th view point, and make the light emitted by the pixel units P of the second pixel island 1012 form the (m + 1)-th view point to the n-th view point, where m is a natural number greater than 1, and n is a natural number greater than (m + 1).

[0041] The lens structure layer 30 is disposed on the side of the dynamic grating layer 20 away from the display panel 10 and includes a plurality of lenses.

[0042] The display component provided by the present disclosure includes a display panel 10, a dynamic grating layer 20, and a lens structure layer 30 which are stacked. Among them, the display panel 10 includes a light-emitting surface and a backlight surface arranged opposite to each other, and the light emitted by the display panel 10 exits from the light-emitting surface; the dynamic grating layer 20 is disposed on the light-emitting surface of the display panel 10 and can dynamically change the width and position of its opening area 201 to control the light emission direction; the lens structure layer 30 is disposed on the side of the dynamic grating layer 20 away from the display panel 10 to project the light of different pixel islands 101 to different areas away from the display panel 10. The side of the lens structure layer 30 away from the display panel 10 is the display side of the display component.

[0043] If a single-layer lens structure layer 30 is used for view angle stitching, the slope angle of the lens is limited by the process, resulting in a limited angle of deflection of the light that the lens can deflect. The display component of the present disclosure embodiment controls the deflection angle of the light beams emitted from the first pixel island 1011 and the second pixel island 1012 by setting the dynamic grating layer 20, and can deflect the light beams to a large angle. Therefore, stitching of a larger view angle can be achieved. The light passing through the opening area 201 of the display component of the present disclosure embodiment propagates according to the principle of linear light propagation. Therefore, the opening area 201 can capture the large-angle light emitted by multiple pixel units P, forming a large view angle. However, if the lens structure layer 30 is not provided, the crosstalk between adjacent viewpoints will be too large due to excessive beam expansion of adjacent pixel units P. Therefore, the display component of the present disclosure embodiment sets the lens structure layer 30 to contract and collimate the light beams diverging from each pixel unit P through the opening area 201, so as to reduce the crosstalk between the viewpoints formed by adjacent pixel units P.

[0044] In some exemplary embodiments, the display panel 10 may further include a pixel definition layer 102. The pixel definition layer 102 is formed with pixel openings corresponding to each pixel island 101 one by one, and any one pixel opening can expose the opening of the corresponding pixel island 101. In some embodiments, the pixel definition layer 102 may be used to define the light-emitting area of the pixel island 101, that is, the pixel definition layer 102 defines the opening of the pixel island 101. In other embodiments of the present disclosure, the pixel definition layer 102 may be used to isolate the light of different pixel islands 101 to avoid crosstalk between different pixel islands 101.

[0045] In some exemplary embodiments, the display panel 10 may further include a circular polarizer, and the circular polarizer may be disposed on the side of the multiple pixel units P away from the substrate to reduce the influence of ambient light on the display effect.

[0046] In some exemplary embodiments, each pixel island 101 may include the effective display areas of multiple pixel units P. Exemplarily, the first pixel island 1011 may include the effective display areas of m pixel units P, and the second pixel island 1012 may include the effective display areas of (n - m) pixel units P. That is, the first pixel island 1011 includes the first pixel unit to the mth pixel unit, and the second pixel island 1012 includes the (m + 1)th pixel unit to the nth pixel unit. m is a natural number greater than 1, and n is a natural number greater than (m + 1). The effective display areas of the multiple pixel units in each pixel island 101 can emit light of different viewpoints respectively. In the present disclosure embodiment, the "effective display area" refers to the area where the pixel unit can emit light or transmit light and perform display.

[0047] For the area where the first pixel island 1011 is located, in the effective display areas of the first pixel unit to the m-th pixel unit, the effective display area of the first pixel unit can emit light of the first viewing angle through the projection of the opening area 201 and the lenticular lens 301, the effective display area of the second pixel unit can emit light of the second viewing angle through the projection of the opening area 201 and the lenticular lens 301,......, the effective display area of the m-th pixel unit can emit light of the m-th viewing angle through the projection of the opening area 201 and the lenticular lens 301; for the area where the second pixel island 1012 is located, in the effective display areas of the (m + 1)-th pixel unit to the n-th pixel unit, the effective display area of the (m + 1)-th pixel unit can emit light of the (m + 1)-th viewing angle through the projection of the opening area 201 and the lenticular lens 301, the effective display area of the (m + 2)-th pixel unit can emit light of the (m + 2)-th viewing angle through the projection of the opening area 201 and the lenticular lens 301,......, the effective display area of the n-th pixel unit can emit light of the n-th viewing angle through the projection of the opening area 201 and the lenticular lens 301. In the embodiments of the present disclosure, the "light of different viewing angles" may refer to pixel points of the same point on the same object under different viewing angles, or pixel points of different points on the same object under different viewing angles.

[0048] To achieve autostereoscopic 3D display, the display device having this display component can be driven according to the following driving method: obtain the positions of both eyes; according to the positions of both eyes, determine the image sub-pixels of each pixel island 101 from the pixel units P of each pixel island 101, and the determined image sub-pixels include left-eye sub-pixels for displaying the left-eye image and right-eye sub-pixels for displaying the right-eye image; by performing specific image rendering on the pixel unit P, drive each left-eye sub-pixel to display the left-eye image and drive each right-eye sub-pixel to display the right-eye image. In this way, the light of one viewing angle among the n viewing angles is received by the left eye, and the light of one viewing angle is received by the right eye. The left eye can see the left-eye image displayed by each left-eye sub-pixel, and the right eye can see the right-eye image displayed by each right-eye sub-pixel, thereby enabling the viewer to see a 3D picture and achieving 3D display.

[0049] In some exemplary embodiments, m can be a natural number between 8 and 15, and n can be a natural number between 16 and 30. Exemplarily, as Figure 4 shown, m = 10 and n = 20.

[0050] In some exemplary embodiments, as Figure 2 shown, the lens structure layer 30 may include a substrate layer 302 and lenticular lenses 301 provided on the side of the substrate layer 302 away from the display panel 10. Preferably, the material of the substrate layer 302 may be the same as that of the lenticular lenses 301, and the substrate layer 302 and the lenticular lenses 301 may be an integral structure.

[0051] In some exemplary embodiments, the multiple lenses are divided into multiple groups, and each group of lenses includes at least two cylindrical lenses 301 arranged in a set direction. Each group of cylindrical lenses 301 can be correspondingly arranged with a pixel island 101.

[0052] In this embodiment, by arranging at least two cylindrical lenses in each group of lenses, the divergence angle of light can be increased, and finally large-angle splicing can be achieved.

[0053] In some exemplary embodiments, as Figure 3 shown, the multiple pixel islands 101 can be arranged non-uniformly.

[0054] In this embodiment, each pixel island 101 is correspondingly arranged with an opening area 201 in the dynamic grating layer 20 and a group of cylindrical lenses 301 in the lens structure layer 30 one by one. The light emitted by each pixel island 101 needs to be projected into the human eye observation range through the correspondingly arranged opening area 201 and cylindrical lenses 301. Therefore, the relative positional relationship between each pixel island 101 located at different positions on the display panel 10 and the correspondingly arranged opening area 201 and cylindrical lenses 301 is different, and the multiple pixel islands 101 can be arranged non-uniformly.

[0055] Exemplarily, when the orthographic projection of the human eye observation range on the display panel 10 is located in the middle area of the display panel 10, the pixel islands 101 located at the edges of the display panel 10 need to deviate from the centers of the correspondingly arranged opening area 201 and cylindrical lenses 301 to ensure that the light emitted by them can be projected into the human eye observation range. In the embodiments of the present disclosure, the specific positions of the areas where each pixel island 101 is located on the display panel 10 can be set according to the size of the display panel 10 and the position and size of the human eye observation range.

[0056] In some exemplary embodiments, as Figure 3 shown, the multiple first pixel islands 1011 are uniformly arranged, and the multiple second pixel islands 1012 are uniformly arranged. In the set direction, the distance between adjacent first pixel islands 1011 is d1, and the distance between adjacent second pixel islands 1012 is d2. d1 may not be equal to d2, or d1 may be equal to d2.

[0057] In some exemplary embodiments, as Figure 5 shown, each pixel island 101 includes an effective display area of multiple pixel units P. The distance between adjacent pixel units P in the first pixel island 1011 is d3, the distance between adjacent pixel units P in the second pixel island 1012 is d4, and the distance between adjacent pixel islands 101 is d5. d3 is less than d5, and d4 is less than d5.

[0058] In some exemplary embodiments, d5 is greater than x times of d3, where x is greater than or equal to 3.

[0059] In some exemplary embodiments, d5 is greater than y times d4, where y is greater than or equal to 3.

[0060] In some exemplary embodiments, the display panel 10 further includes a spacer region disposed around the plurality of pixel islands 101; the spacer region may be a non-display region, that is, no pixel unit P or no effective display area of the pixel unit P is provided in the spacer region, and no light emission or light transmission display is performed. No effective display area of the pixel unit P is provided in the spacer region of the display panel 10 according to the embodiment of the present disclosure. On the one hand, the utilization rate of the pixel unit P can be improved, and on the other hand, materials and costs can be saved.

[0061] In this embodiment, the effective display areas of all the pixel units P of the display panel 10 are distributed in the regions where the plurality of pixel islands 101 of the display panel 10 are located. No pixel unit P or no effective display area of the pixel unit P may be provided between the plurality of pixel islands 101. Each pixel island 101 is correspondingly provided with an opening area 201 of the dynamic grating layer 20 and a group of lenticular lenses 301 of the lens structure layer 30. At this time, the plurality of pixel islands 101 can be used for display, while the spacer region between the plurality of pixel islands 101 is not used for display and no pixel unit P or no effective display area of the pixel unit P is provided, so that while realizing integral imaging, the pixel utilization rate of the display panel can be improved. For example, the pixel utilization rate of the display panel can reach 100%.

[0062] In some exemplary embodiments, as Figure 5 shown, each pixel unit P may include a driving element 103; the driving element 103 may be located in the spacer region and is connected to the effective display area of the corresponding pixel unit P through a wire, that is, the driving element 103 may be disposed outside the pixel island 101. Thus, more effective display areas of the pixel unit P can be provided in the pixel island 101, and thus the resolution or PPI of the region where each pixel island 101 is located can be improved.

[0063] In this embodiment, since no pixel unit P is provided in the spacer region between the plurality of pixel islands 101, and each pixel island 101 may only include the effective display areas of the plurality of pixel units P, some driving elements of the pixel unit P (exemplarily, the driving elements may include thin film transistors) may be disposed in the spacer region between the plurality of pixel islands 101 instead of in the pixel island 101, so that more effective display areas of the pixel unit P can be provided in the pixel island 101, and thus the resolution or PPI of the region where each pixel island 101 is located can be improved.

[0064] In some exemplary embodiments, the display panel 10 provided by the embodiments of the present disclosure may be an organic light-emitting device (OLED) display panel, a micro light-emitting diode (Micro LED) display panel, a mini light-emitting diode (Mini LED) display panel, a liquid crystal display (LCD) display panel, or other types of display panels.

[0065] Micro light-emitting diode display panels and mini light-emitting diode display panels have characteristics such as small sub-pixels, high brightness, and low placement height. In the display assembly of the embodiments of the present disclosure, the micro light-emitting diode display panel or the mini light-emitting diode display panel is arranged in a pixel island pattern. Since the deflection angle of the light at the edge of the display panel is very large, the dislocation between each pixel island and the opening area corresponding to the dynamic grating layer is unequal.

[0066] In some exemplary embodiments, the first pixel island 1011 and the second pixel island 1012 are alternately arranged along the first direction D1 or the second direction D2, and the first direction D1 intersects the second direction D2.

[0067] In some exemplary embodiments, the opening of at least one pixel island 101 may be arranged in a parallelogram. The long side direction of the opening of the pixel island 101 may be the first direction D1, and the short side direction may be the second direction D2, where both the first direction D1 and the second direction D2 are directions parallel to the light-emitting surface of the display panel 10. In other words, the short side direction of the opening of the pixel island 101 may be parallel to the extending direction of the cylindrical lens 301. In some embodiments, the second direction D2 is perpendicular to the set direction, and the first direction D1 is the same as the set direction. Thus, the opening of the pixel island 101 may be rectangular. In another embodiment of the present disclosure, the set direction intersects the first direction D1.

[0068] In some exemplary embodiments, the first direction D1 is the same as the row direction of the display panel 10, and the second direction D2 is the same as the column direction of the display panel 10. Wherein, the row direction of the display panel 10 may be the extending direction of the scanning signal lines of the display panel 10, and the column direction of the display panel 10 may be the extending direction of the data signal lines of the display panel 10.

[0069] In some exemplary embodiments, such as Figure 6As shown, multiple pixel islands 101 can be arranged in multiple columns, and any pixel island column includes multiple pixel islands 101 arranged along the second direction D2. In this way, crosstalk between the left-eye view and the right-eye view can be reduced, and the display effect of naked-eye 3D can be improved. Moreover, this also facilitates determining the image sub-pixels of each pixel island 101 in the same pixel island column simultaneously, and simplifies the driving method of the display component.

[0070] In some exemplary embodiments, multiple pixel islands 101 can also be arranged in multiple rows, where any pixel island row includes multiple pixel islands 101 arranged along the first direction D1.

[0071] In some exemplary embodiments, as Figure 6 shown, multiple pixel islands 101 are arranged in multiple pixel island rows and multiple pixel island columns. Among them, any pixel island column includes multiple first pixel islands 1011 or second pixel islands 1012 arranged along the second direction D2, any pixel island row includes multiple first pixel islands 1011 or second pixel islands 1012 arranged along the first direction D1, and one pixel island column in any two adjacent pixel island columns includes multiple first pixel islands 1011 arranged along the second direction D2, and the other pixel island column includes multiple second pixel islands 1012 arranged along the second direction D2; one pixel island row in any two adjacent pixel island rows includes multiple first pixel islands 1011 arranged along the first direction D1, and the other pixel island row includes multiple second pixel islands 1012 arranged along the first direction D1. Among them, two adjacent pixel islands 101 in the same pixel island column are respectively located in two pixel island rows separated by one pixel island row, and two adjacent pixel islands 101 in the same pixel island row are respectively located in two pixel island columns separated by one pixel island column.

[0072] In some other exemplary embodiments, as Figure 7 shown, pixel islands 101 are arranged in multiple pixel island rows and multiple pixel island columns. Among them, any pixel island column includes multiple first pixel islands 1011 or second pixel islands 1012 arranged along the second direction D2, and any pixel island row includes multiple first pixel islands 1011 and second pixel islands 1012 arranged alternately along the first direction D1. Among them, two adjacent pixel islands 101 in the same pixel island column are located in two adjacent pixel island rows.

[0073] In some exemplary embodiments, the light-emitting position of the opening region 201 is located on the focal plane of the cylindrical lens 301. Thus, crosstalk between the left-eye image seen by the left eye and the right-eye image seen by the right eye can be reduced, thereby improving the 3D display effect. Moreover, this also facilitates determining the farthest viewing limit and the nearest viewing limit of the display component, and facilitates determining the left-eye sub-pixels for displaying the left-eye image and the right-eye sub-pixels for displaying the right-eye image, which helps reduce the complexity of the driving method of the display device applying this display component. In the embodiments of the present disclosure, the focal plane of the cylindrical lens 301 is the plane where the foci on the same side of each cylindrical lens 301 are located, that is, the plane passing through the focus of the cylindrical lens 301 and perpendicular to the principal optical axis of the cylindrical lens 301.

[0074] In some exemplary embodiments, the alignment positions of the plurality of opening regions 201 and the plurality of pixel islands 101 are different, and the alignment positions of the plurality of sets of cylindrical lenses 301 and the plurality of pixel islands 101 are different, but the plurality of opening regions 201 and the plurality of sets of cylindrical lenses 301 can make the respective visible regions of the first pixel island 1011 and the second pixel island 1012 equivalent to a closely connected state on the display side.

[0075] In some exemplary embodiments, the size of each pixel island 101 in the set direction is between 10 micrometers and 100 micrometers.

[0076] In some exemplary embodiments, there is no overlap between the visible regions corresponding to the plurality of pixel units P of the first pixel island 1011 and the visible regions corresponding to the plurality of pixel units P of the second pixel island 1012. Therefore, in the 3D visible space, the pupil of one eye will not see the same pixel unit P in the first pixel island 1011 or the second pixel island 1012 through two different sets of cylindrical lenses 301. Based on this, when 2D display is required, each pixel unit P can be made to display a 2D picture, and then the viewer can see the 2D picture, and there will be no defect of fluctuating display brightness in the set direction. In other words, the display component of this embodiment can also achieve uniform-brightness 2D display by simultaneously driving each pixel unit P to display a 2D picture.

[0077] In some exemplary embodiments, the dynamic grating layer 20 can be any one of the following: liquid crystal grating, electro-wetting grating, electrochromic (ECD) grating, etc. The dynamic grating layer in the embodiments of the present disclosure is not limited to the above three, as long as it is a device that can achieve variable widths of the light-shielding region and the opening region 201 (light-transmitting region). By controlling the voltage, the position and width of the opening region 201 of the dynamic grating layer can be controlled, thereby adjusting the viewing angle of the display device.

[0078] In some exemplary embodiments, a plurality of grating periods T are set in one-to-one correspondence with a plurality of pixel islands 101. As the distance between the grating period and the center line of the display panel increases, the opening region 201 of the grating period is gradually offset from the center line of the corresponding pixel island 101, and the opening region 201 of each grating period is located between the center line of the corresponding pixel island 101 and the center line of the display panel.

[0079] In some exemplary embodiments, as the distance between the grating period and the center line of the display panel increases, the offset distance between the opening region 201 of the grating period and the center line of the corresponding pixel island 101 increases.

[0080] In some exemplary embodiments, adjacent two sets of cylindrical lenses 301 can be connected to each other. That is, in the lens structure layer 30, the filling rate of the cylindrical lenses 301 is 100%. In this way, not only can the width of the cylindrical lenses 301 in the set direction be increased to facilitate the preparation of the cylindrical lenses 301, but also the light-shielding strips located between the cylindrical lenses 301 can be avoided in the lens layer 200, and further, the display component can have a greater light-emitting efficiency and display brightness.

[0081] In some other exemplary embodiments, the lens structure layer 30 may further include a plurality of light-shielding strips arranged along a set direction, and each light-shielding strip is alternately arranged with each group of cylindrical lenses 301. In other words, there is a gap between adjacent two sets of cylindrical lenses 301, and a light-shielding strip for light shielding is arranged in the gap to avoid the influence of stray light emitted from the gap on the display effect.

[0082] The embodiments of the present disclosure further provide a display device, including: the display component described in any of the above embodiments. The display device can be any product or component with a display function, such as a smart phone, a tablet computer, a television, a monitor, a notebook computer, a digital photo frame, a navigator, etc.
