Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display substrate, a display device, and a display control method. Background Technology

[0002] With technological advancements, some display devices can support both 2D and 3D display modes. For example, in 3D display mode, multi-view light field display devices use optical elements such as microlens arrays or gratings to segment and directionally project multiple sets of parallax images, allowing eyes at different horizontal and vertical positions to capture the corresponding viewpoint. Thus, the viewer's left eye receives only the left-eye view, and the right eye receives only the right-eye view, creating a 3D image effect by separating the visible images for the left and right eyes. In 2D display mode, the viewer's left and right eyes receive the same image, and its operating mode is the same as existing conventional 2D display devices. In related technologies, display devices only support unidirectional viewing, but users also have a need for stereoscopic viewing on flexible display devices such as mobile phones and tablets. In this case, it is necessary to meet both horizontal and vertical viewing requirements. Summary of the Invention

Detailed Implementation

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] The terms "first," "second," etc., used in the embodiments of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or devices. Additionally, the use of "and / or" in this application indicates at least one of the connected objects, such as A and / or B and / or C, representing seven possibilities: including A alone, B alone, C alone, and the presence of both A and B, both B and C, both A and C, and the presence of A, B, and C.

[0023] This application provides a display substrate.

[0024] like Figure 1 and Figure 2 As shown, in one embodiment, the display substrate includes a substrate, a light-controlling element 101 and a plurality of sub-pixels 102 disposed on the substrate. The display substrate can be a passive display device, such as a liquid crystal display (LCD), or an active display device, such as an OLED (Organic Light Emitting Diode).

[0025] The plurality of sub-pixels 102 include a first sub-pixel and a second sub-pixel, and the light control element 101 is used to project the light from the first sub-pixel and the light from the second sub-pixel in different directions.

[0026] Traditional two-dimensional display devices can only provide a single planar image. To present a three-dimensional effect, automatic stereoscopic display technology that utilizes the principle of parallax has emerged, namely naked-eye 3D (three-dimensional) display.

[0027] This type of technology typically involves setting a light control element 101 on the display panel. The light control element 101 is generally a grating or a cylindrical lens, which projects two slightly different images corresponding to the left and right eyes onto the viewer's left and right eyes respectively, and then merges them in the brain to form stereoscopic vision.

[0028] Currently, many applications, such as smartphones, tablets, and public information displays, require display devices to present good 3D display effects in both landscape and portrait modes simultaneously. However, in traditional designs, the extension direction of the light control element 101 (such as a grating or lens array) is usually parallel to the row or column direction of the display substrate. When such a display device rotates between landscape and portrait modes, the optical system, originally optimized for one direction, will experience severe crosstalk, brightness reduction, and narrow viewing angle in the other direction, resulting in a significant decrease in 3D display quality.

[0029] In one embodiment of this application, the display substrate has a first observation direction and a second observation direction, wherein the first observation direction and the second observation direction are different directions.

[0030] Generally speaking, the first observation direction is the horizontal direction of the display substrate, which is... Figure 1 and Figure 2 The horizontal direction shown in the diagram, and the second observation direction, are the vertical directions of the display substrate. Figure 1 and Figure 2 The image shows the longitudinal direction. These two directions are also the two most common viewing directions for display devices in practical applications. Therefore, this embodiment will only be described by way of example, with the first viewing direction being the horizontal direction of the display substrate and the second viewing direction being the longitudinal direction of the display substrate.

[0031] The light-controlling element 101 primarily functions to guide light. It converges or guides light from the first sub-pixel to a specific angular range, while simultaneously guiding light from the second sub-pixel to another angular range. These two angular ranges differ slightly, resulting in a difference between the images received by the user's left and right eyes. The user's brain then merges these two images with parallax, creating a sense of depth.

[0032] In the technical solution of this embodiment, the extension direction of the light control element 101 intersects with the first observation direction and also with the second observation direction.

[0033] In this embodiment, the extension direction of the light control element 101 refers to the basic direction axis of the light control element 101. For example, when the light control element 101 is a lens, the extension direction refers to the axial direction of the lens.

[0034] Because the extension direction of the light-controlling element 101 is inclined relative to the horizontal and vertical directions, its physical structure is no longer biased towards either viewing direction. Therefore, when the display device is placed horizontally, the light-controlling element 101 can effectively guide light to the horizontally aligned eyes; when the display device is placed vertically, the same structure of the light-controlling element 101 can effectively guide light to the vertically aligned eyes. This achieves the goal of obtaining high-quality 3D display effects in both horizontal and vertical modes.

[0035] In the embodiments of this application, the light control element 101 may be selected, but is not limited to, a barrier and a lens array.

[0036] By setting the extension direction of the light control element 101 to intersect with both the horizontal and vertical directions of the display substrate, the traditional design's reliance on a single viewing direction is broken. This enables the 3D display device to provide a stereoscopic viewing experience with moderate width, low crosstalk, and uniform brightness in both the horizontal and vertical main usage modes, greatly improving the product's practicality and user experience.

[0037] In some embodiments, the angle between the first observation direction and the extension direction of the light control element 101 is 30° to 60°, and the angle between the second observation direction and the extension direction of the light control element 101 is also 30° to 60°.

[0038] Furthermore, in some embodiments, the first observation direction and the second observation direction are perpendicular to each other, and the angle between the first observation direction and the extension direction of the light control element 101 is 45°, and the angle between the second observation direction and the extension direction of the light control element 101 is also 45°.

[0039] It's important to understand that the first viewing direction (horizontal) and the second viewing direction (vertical) represent the two most frequently viewed directions of a display device. In most applications, these two directions are perpendicular to each other, corresponding to the device's horizontal (landscape) mode and vertical (portrait) mode, respectively. For example, watching videos in landscape mode and browsing web pages in portrait mode on a smartphone are typical applications of these two modes.

[0040] In this embodiment, the extension direction of the light control element 101 determines the directionality of its light splitting or guiding capability. The angle between the extension direction of the light control element 101 and the observation direction is specified to be between 30° and 60°, which means that the light control element 101 is significantly "tilted" relative to the horizontal and vertical borders of the screen, rather than the traditional parallel or vertical layout, thereby breaking the "dependence" of the light control element 101 on a single observation direction.

[0041] It is important to understand that if the angle is 0° or 90°, meaning the light control element 101 is completely parallel to one observation direction, while this is beneficial for parallax separation in that direction, it will severely sacrifice the viewing effect in the vertical direction, leading to a sharp increase in crosstalk and a narrowing of the viewing angle in the other observation direction. The purpose of setting the tilt angle is to make the adjustment methods of the light control element 101 in the two directions more similar, thereby achieving effective control of light in both the horizontal and vertical directions.

[0042] Furthermore, when the angle between the light control element 101 and both the horizontal and vertical directions is 45°, the adjustment levels of the optical characteristics of the horizontal and vertical observations, such as the viewing angle, the optimal viewing distance, and the crosstalk level, are more similar, which can balance the observation effect of the display device in both the horizontal and vertical directions.

[0043] Furthermore, the tilted arrangement of the light-controlling elements 101 creates conditions for the arrangement of the underlying sub-pixels 102, which helps to hide the gaps between the sub-pixels 102, suppress moiré patterns, and potentially achieve higher perceived visual resolution at the same physical pixel density. At the same time, this layout may also provide more layout space for metal traces such as gate lines and data lines, which is beneficial for achieving a higher aperture ratio design, thereby improving display brightness or reducing power consumption.

[0044] Please also refer to Figure 2 and Figure 3 In this embodiment, a 7-viewpoint view with the light-controlling element 101 at 45° angles to both the horizontal and vertical directions is used for illustrative purposes. Figure 2 The image shows one two-dimensional display pixel 11 and six three-dimensional display pixels 12. Because the light-controlling element 101 has equal angles with both the horizontal and vertical directions, the viewpoint images of each of the three-dimensional display pixels 12 are uniformly modulated and split in all directions. When viewed horizontally, the left eye sees 5 viewpoints and the right eye sees 2 viewpoints; when viewed vertically, the left eye sees 2 viewpoints and the right eye sees 5 viewpoints. With the viewpoints of both eyes spaced the same, and the viewpoint images adjusted, the resolution and depth of field of the stereoscopic image are the same when viewed horizontally and vertically.

[0045] In some embodiments, a plurality of sub-pixels 102 are arranged in an array, the sub-pixels 102 are rectangular, and the length direction of the sub-pixels 102 intersects with a first observation direction and a second observation direction. Further, in some embodiments, the length direction or width direction of the sub-pixels 102 is set along the extension direction of the light control element 101.

[0046] In this embodiment, the pixels are arranged along the extension direction of the light control element 101, which enables the light control element 101 to adjust the light of each sub-element more accurately, reducing the possibility of light leakage to the wrong viewing angle, and thus effectively reducing crosstalk between the left and right eye images.

[0047] Furthermore, this arrangement achieves optimal matching between the effective light-emitting area of ​​the sub-pixels 102 and the light-collecting area of ​​the light-controlling element 101, reducing light waste caused by the internal circuitry of the pixels or the light-controlling element 101 itself. Simultaneously, it ensures that all sub-pixels 102 serving the same viewing angle have consistent optical paths and light-emitting characteristics, effectively avoiding brightness differences in different areas of the screen and providing stable, uniform, high-quality 3D images for both horizontal and vertical viewing modes.

[0048] like Figure 4 As shown, in some embodiments, along the length direction of sub-pixels 102, the bottom edge of the Nth row of sub-pixels 102 and the top edge of the (N+1)th row of sub-pixels 102 are on the same straight line, where N is a positive integer. It should be understood that a pixel row along the length direction of sub-pixels 102 refers to... Figure 4 The diagonal pixel rows can also be understood as along... Figure 4 The pixel row in the direction of the top left corner line. For example... Figure 4 As shown, the straight line coincides with the bottom edge of the pixel to its upper left and the top edge of the pixel to its lower right.

[0049] In this embodiment, the sub-pixels 102 within a row are strictly aligned, and the rows are closely adjacent but do not overlap, ensuring a regularity in the position of the light-emitting center of each sub-pixel 102. When used in conjunction with the light-controlling element 101, it ensures that light from different views is separated more precisely. The directionality of the light is more accurate, and interference between different viewing angles is reduced, thereby significantly reducing crosstalk and providing viewers with a pure and stable stereoscopic visual effect.

[0050] like Figure 5 As shown, in some embodiments, along the length direction of sub-pixels 102, the straight line containing the top edge of the (N+1)th row of sub-pixels 102 intersects the Nth row of sub-pixels 102, and the straight line containing the bottom edge of the (N+1)th row of sub-pixels 102 intersects the (N+2)th row of sub-pixels 102, where N is a positive integer.

[0051] Please continue reading. Figure 5 , Figure 5 The dashed line along the top and bottom edges of one diagonal pixel row intersects with the other two pixel rows. In the technical solution of this embodiment, when the light control element 101 guides the light, the light beams from different views may partially overlap; however, the higher aperture ratio of the display substrate helps to improve resolution and display effect.

[0052] Please see Figure 6 and Figure 7 , Figure 6The horizontal axis represents the observer's viewing angle (horizontal offset angle relative to the screen), and the vertical axis represents light intensity, specifically the light intensity received by the human eye from a certain viewpoint (or sub-pixel) at a specific horizontal viewing angle. The peak of the curve represents the optimal viewing angle of that viewpoint, and the width of the curve represents the viewing angle range of that viewpoint.

[0053] like Figure 6 As shown, overlapping sub-pixels occur along the lens axis, which increases crosstalk between viewpoints. Figure 7 As shown, for small-sized mobile phones, multiple viewpoints can be combined into two viewpoints, which can effectively improve the stereoscopic resolution of the combined viewpoints and enhance the display effect. Therefore, Figure 5 The solution shown is more suitable for small-sized display devices.

[0054] like Figure 2 and Figure 4 As shown, in some embodiments, the display substrate includes a two-dimensional display pixel 11, which is composed of a plurality of sub-pixels 102 of different colors, and the sub-pixels 102 included in the two-dimensional display pixel 11 are arranged in a square. In some embodiments, the number of sub-pixels 102 of each color included in the two-dimensional display pixel 11 is the same. In some embodiments, the sub-pixels 102 of different colors are of the same size.

[0055] In this embodiment, the two-dimensional display pixels 11 are arranged in a square pattern, meaning that the two-dimensional display pixels 11 have essentially the same physical size and spatial frequency in both the horizontal and vertical directions. After light is emitted from the square pixel unit, the controlled light element 101 guides the optical path in both the horizontal and vertical directions, and the modulation method is essentially symmetrical. This ensures that key optical parameters such as viewing angle, optimal viewing distance, and color mixing uniformity obtained in both the horizontal and vertical observation directions are essentially the same.

[0056] Furthermore, in this embodiment, the number of sub-pixels 102 for each color is equal, and the size of each sub-pixel 102 is the same. This provides a cleaner and more stable image in both viewing directions when displaying the image. The attenuation behavior of each color of light is synchronous and consistent in both horizontal and vertical viewing angles. This avoids color drift caused by premature attenuation of a certain color in one viewing direction, thus ensuring that the horizontal and vertical viewing directions have almost the same viewing angle width and color stability. This reduces the difference in visual effects between horizontal and vertical viewing angles, thereby providing users with a better display experience.

[0057] like Figure 2As shown, in some embodiments, the display substrate includes a three-dimensional display pixel 12, and each sub-pixel 102 of the three-dimensional display pixel 12 is arranged along the extension direction of the light control element 101.

[0058] In this embodiment, the sub-pixels 102 of the three-dimensional display pixel 12 are arranged along the direction of the inclined light-controlling element 101, forming a "sub-pixel chain" in physical space at a specific angle to the observation direction. For both the horizontal and vertical observation directions, the geometric relationship of this "sub-pixel chain" is quite close. Furthermore, when the horizontal and vertical angles of the display substrate are both 45°, the angles between the "sub-pixel chain" and the horizontal and vertical angles of the display substrate are the same. This means that when the light-controlling element 101 guides light, the light path acting on the horizontal observation and the light path acting on the vertical observation have similar or even identical physical constraints and optical efficiencies. Thus, the three-dimensional viewing angle width, optimal viewing distance, and overall brightness obtainable from the two viewing angles are very close, eliminating the inherent defect of a wide viewing angle in one direction and a narrow viewing angle in the other in traditional designs.

[0059] Furthermore, this design avoids the problem of subpixels 102 being too densely arranged in one viewing direction, leading to increased crosstalk, while being too sparse in another direction, resulting in a loss of optical efficiency. Therefore, whether viewed horizontally or vertically, the level of stereoscopic image crosstalk perceived by the viewer is controlled within a low and similar range, thus ensuring a clear and comfortable 3D visual experience in both main usage modes.

[0060] In some embodiments, the display substrate also includes: A gate bus matrix arranged along a first observation direction of the display substrate and extending along a second observation direction of the display substrate; and a source bus matrix extending along the first observation direction of the display substrate and arranged along the second observation direction of the display substrate.

[0061] In this embodiment, the gate line and the source line form an orthogonal grid, which can make the most efficient use of the wiring space on the substrate. This solution is similar to related technologies and can effectively reduce design and development costs, creating favorable conditions for increasing the aperture ratio.

[0062] This application provides a display device including the display substrate described in any of the above embodiments.

[0063] The display device in this embodiment includes all the technical solutions of the above-described display substrate embodiments, and therefore can achieve at least all of the above-described technical effects, which will not be repeated here.

[0064] This application provides a display control method applied to the display device described above, the method comprising: Detect the target orientation of the user relative to the display device; The interlacing diagram corresponding to the target direction is invoked to display the image.

[0065] like Figures 8 to 10 As shown, when a user views the display device from different angles, the corresponding viewpoints for each eye are different.

[0066] by Figure 9 As shown, when viewing from direction A, the left eye corresponds to viewpoint 2 and the right eye corresponds to viewpoint 5; when viewing from direction B, the left eye corresponds to viewpoint 5 and the right eye corresponds to viewpoint 2; when viewing from direction C, the left eye corresponds to viewpoint 5 and the right eye corresponds to viewpoint 2; when viewing from direction D, the left eye corresponds to viewpoint 2 and the right eye corresponds to viewpoint 5.

[0067] At this point, when the user views from points A and D, the depth of field in the stereoscopic view is displayed normally. However, when the user views from points B and C, the stereoscopic view is not displayed correctly, and the depth of field is reversed.

[0068] To further improve the display effect, this embodiment further adjusts the image display according to the relative position of the user and the display device.

[0069] For example, Figure 8 CTV Figures 1 to 6 These are images taken / created from a left-to-right perspective, when the user... Figure 10 When viewing from direction A or direction D, use Figure 8 The diagram shown illustrates the interlacing of data when the user... Figure 10 When viewing from direction B or C, use Figure 9 The interlacing pattern shown ensures a relatively uniform visual effect when viewed from different directions.

[0070] In one exemplary embodiment, this solution is applied to a stereoscopic display device, such as... Figure 11 As shown, during implementation, the motion state of the display screen is first detected by devices such as speed sensors and acceleration sensors to calculate the angle of the display screen relative to the user. After determining the angle of the display screen relative to the user, the corresponding view interleaving is adopted according to the user's position to ensure the visual effect of the image observed by the user.

[0071] This application also provides a readable storage medium storing a program or instructions.
