Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0024] Please refer to Figure 1 , Figure 1 This is a partial structural schematic diagram of a display device provided in an embodiment of this application. The display device 000 may include: a display panel 100, a control electrode layer 200, and a gel film 300.
[0025] The control electrode layer 200 in the display device 000 is located on the display side of the display panel 100, and the gel film 300 in the display device 000 is located on the side of the control electrode layer 200 away from the display panel 100.
[0026] The display device 000 is configured to control the shape of the gel film 300 away from the display panel 100 by applying an electrical control signal to the control electrode layer 200, so that the display area of the display device 000 is in a two-dimensional (2D) display mode and / or a three-dimensional (3D) display mode.
[0027] like Figure 1 As shown, in two-dimensional display mode, the side of the gel film 300 facing away from the display panel 100 is parallel to the display surface of the display panel 100; as Figure 2 As shown, Figure 2 This is a partial structural schematic diagram of another display device provided in the embodiments of this application. In the three-dimensional display mode, the gel film 300 has a plurality of cylindrical lenses 300a on the side opposite to the display panel 100.
[0028] It should be noted that in this embodiment, the gel film 300 can be a flexible film layer made of polyvinyl chloride (PVC) material with good light transmittance. When the side of the gel film 300 facing away from the display panel 100 is parallel to the display surface of the display panel 100, the gel film 300 has little impact on the transmitted light. Therefore, when the display device 000 is in two-dimensional display mode, even if the gel film 300 is provided on the light-emitting side of the display panel 100, the gel film 300 has little impact on the clarity, brightness, and color of the displayed image, thus avoiding image quality degradation. Furthermore, by applying an electrical control signal to the control electrode layer 200 to form an electric field and adjusting the shape of the side of the gel film 300 facing away from the display panel 100, the display mode of the display device 000 can be adjusted, making the switching between 2D and 3D display modes more flexible.
[0029] In summary, the display device provided in this application includes a display panel, a control electrode layer, and a gel film. The display device is configured to control the shape of the gel film facing away from the display panel by applying an electrical control signal to the control electrode layer, thereby enabling the display area of the display device to be in a two-dimensional display mode and / or a three-dimensional display mode. In the two-dimensional display mode, the side of the gel film facing away from the display panel is parallel to the display surface of the display panel; in the three-dimensional display mode, the side of the gel film facing away from the display panel has multiple cylindrical lenses. When the side of the gel film facing away from the display panel is parallel to the display surface of the display panel, the gel film has less influence on the transmitted light. Therefore, even if a gel film is provided on the light-emitting side of the display panel when the display device is in two-dimensional display mode, the gel film has less influence on the clarity, brightness, and color of the displayed image, thus avoiding image quality degradation. Furthermore, by applying an electrical control signal to the control electrode layer to form an electric field and adjusting the shape of the gel film facing away from the display panel, the display mode of the display device can be adjusted, making the switching between 2D and 3D display modes more flexible.
[0030] The details and functions of the display device 000 provided in the embodiments of this application will be described in more detail below.
[0031] In some embodiments, please refer to Figure 3 , Figure 3This is a partial top view of a display device according to an embodiment of this application. The control electrode layer 200 in the display device 000 may include a plurality of first electrode portions 201a and a plurality of second electrode portions 201b, which are alternately arranged in a first direction X. Here, the first direction X may be parallel to the display surface of the display device 000.
[0032] Please refer to Figure 4 and Figure 5 , Figure 4 This is a partial top view of a gel membrane provided in an embodiment of this application. Figure 5 This is a partial structural schematic diagram of another display device provided in an embodiment of this application. The gel film 300 in the display device 000 may include a plurality of gel portions 301 arranged in a first direction X, the plurality of gel portions 301 corresponding to a plurality of first electrode portions 201a, and each gel portion 301 covering a corresponding first electrode portion 201a. Here, the gel portions 301 may extend along a second direction Y. Here, the second direction Y may be parallel to the display surface of the display device, and the second direction Y may intersect with the first direction X. For example, the second direction Y may be perpendicular to the first direction X.
[0033] Each first electrode portion 201a is configured to cooperate with an adjacent second electrode portion 201b to adjust the shape of the corresponding gel portion 301 on the side facing away from the display panel 100.
[0034] In this way, the multiple gel portions 301 in the gel film 300 can be individually controlled by the corresponding first electrode portion 201a. The display screen can be divided into multiple regions arranged in the first direction X. Each region can have at least one gel portion 301. At the same time that the display device 000 displays a certain screen, the shapes of the multiple gel portions 301 on the side away from the display panel 100 can be different, thereby adjusting the display mode of different areas of the display screen and presenting a better display effect to the viewer.
[0035] Furthermore, 3D display effects can be achieved using gel film 300 for both 3D and 2D image sources.
[0036] In some embodiments, please refer to Figure 6 , Figure 6 This is a partial top view of another display device provided in an embodiment of this application. Multiple first electrode portions 201a and multiple second electrode portions 201b are alternately arranged in a row along a first direction X, and the multiple rows of electrode portions 201 can be arranged along a second direction Y. In this case, please refer to... Figure 7 , Figure 7This is a partial top view of another gel film structure provided in this application embodiment. The gel film 300 may include a plurality of gel portions 301 arranged in an array, that is, the plurality of gel portions 301 are arranged in multiple columns in the first direction X and in multiple rows in the second direction Y. In this way, the display screen can be divided into multiple areas arranged in an array, and each area may have at least one gel portion 301 distributed therein. At the same time that the display device 000 displays a certain screen, the shapes of the multiple gel portions 301 on the side facing away from the display panel 100 may be different, thereby adjusting the display mode of different areas of the display screen and presenting a better display effect to the viewer. Furthermore, in this case, the gel film 300 can adjust the display mode of different areas of the display screen more precisely and flexibly.
[0037] It should be noted that, in the case of multiple gel portions 301 arrays, in three-dimensional display mode, the side of the gel portion 301 facing away from the display panel 100 can be in the shape of a cylindrical lens, or the side of the gel portion 301 facing away from the display panel 100 can also be in the shape of a hemispherical lens. This application does not impose any limitations on this.
[0038] In some embodiments, each first electrode portion 201a in the control electrode layer 200 is configured such that, when an electric field is formed between it and an adjacent second electrode portion 201b, the corresponding gel portion 301 on the side facing away from the display panel 100 is adjusted to have the shape of a cylindrical lens. When no electric field is formed between it and an adjacent second electrode portion 201b, the corresponding gel portion 301 on the side facing away from the display panel 100 is adjusted to be a plane parallel to the display surface of the display panel 100.
[0039] Alternatively, in other embodiments, the first electrode portion 201a may be configured such that, when an electric field is formed between it and the adjacent second electrode portion 201b, the side of the corresponding gel portion 301 facing away from the display panel 100 is adjusted to be a plane parallel to the display surface of the display panel 100. When no electric field is formed between it and the adjacent second electrode, the side of the corresponding gel portion 301 facing away from the display panel 100 is adjusted to have the shape of a cylindrical lens. This application does not impose any limitations on this.
[0040] The morphology of the gel film 300 can be controlled by setting an electric field through the control electrode layer 200. The control method and the structure of the display device 000 can both be relatively simple.
[0041] In some embodiments, please refer to Figure 8 , Figure 8 This is a partial top view of another display device provided in the embodiments of this application, wherein the plurality of first electrode portions 201a can be divided into at least two electrode groups Z ( Figure 8In the Z1-Z3 groups, each electrode group Z contains at least one first electrode portion 201a and is used to receive the same electronic control signal. The first electrode portions 201a in different electrode groups Z can receive the same or different electronic control signals. Here, multiple second electrode portions 201b in the display device 000 can receive the same electronic control signal. Thus, by adjusting only the electronic control signal received by the first electrode portion 201a, the electric field between the first electrode portion 201a and the second electrode portion 201b can be adjusted, thereby adjusting the shape of the corresponding gel portion 301 on the side facing away from the display panel 100.
[0042] In this way, the display screen can be divided into multiple regions Q corresponding to multiple electrode groups Z ( Figure 8 In the case where an electrode group Z includes at least one first electrode portion 201a, at least one gel portion 301 may be distributed in the area Q of the display screen corresponding to this electrode group Z. The gel portion 301 adjusts its shape on the side away from the display panel 100 according to the electronic control signal connected to the first electrode portion 201a, thereby adjusting the display mode of the area Q.
[0043] When the first electrode portion 201a of the same electrode group Z is used to receive the same electronic control signal, the shape of the gel portion 301 corresponding to the same electrode group Z on the side facing away from the display panel 100 is the same. When the first electrode portion 201a in different electrode groups Z receives the same electronic control signal, the shape of the gel portion 301 corresponding to different electrode groups Z on the side facing away from the display panel 100 is the same; when the first electrode portion 201a in different electrode groups Z receives different electronic control signals, the shape of the gel portion 301 corresponding to different electrode groups Z on the side facing away from the display panel 100 is different. Therefore, by dividing the electrode groups Z, the display screen of the display device 000 can be controlled in zones.
[0044] For example, please refer to Figure 9 , Figure 9 This is a partial top view of another display device provided in the embodiments of this application. The display area in the display device 000 may include: a first display partition 001 and a second display partition 002. At least one electrode group Z may be distributed in both the first display partition 001 and the second display partition 002.
[0045] The display device 000 is configured to: apply a first electrical control signal K1 to each first electrode portion 201a in the first display partition 001, and apply a second electrical control signal K2 to each second electrode portion 201b in the first display partition 001, such that each gel portion 301 in the first display partition 001 has a cylindrical lens 300a shape on the side facing away from the display panel 100, so that the first display partition 001 is in a three-dimensional display mode. And / or, apply the second electrical control signal K2 to each first electrode portion 201a and each second electrode portion 201b in the second display partition 002, such that each gel portion 301 in the second display partition 002 has a plane parallel to the display surface of the display panel 100 on the side facing away from the display panel 100, so that the second display partition 002 is in a two-dimensional display mode.
[0046] In related technologies, the display device 000 can only globally switch between two-dimensional and three-dimensional display modes for the entire display area. Compared with related technologies, the embodiments of this application implement zoned control of the display area, which allows different display modes to be applied to different display content on the display screen at a certain moment, in order to meet the viewing needs of different viewers. For example, in an in-vehicle display device, the first display zone 001 can be an entertainment display area near the passenger seat, and the second display zone 002 can be a central control display area near the driver's seat. In this way, a three-dimensional display effect can be presented to passengers when they use the entertainment display area to play images or videos, while a two-dimensional display effect can be presented to the driver when they use the central control display area to view navigation and other information, without interference, which is conducive to ensuring driving safety. For example, in in-vehicle displays, the display area containing vehicle speed information and Advanced Driving Assistance System (ADAS) information in the instrument panel can be presented in three dimensions, while the display area containing other information in the instrument panel can be presented in two dimensions. This makes it easier for drivers to focus on vehicle speed and ADAS information during driving, thereby improving driving convenience and further ensuring driving safety.
[0047] In some embodiments, such as Figure 10 As shown, Figure 10 This is a partial structural schematic diagram of another display device provided in the embodiments of this application. For two different electrode groups Z, the two electrode groups Z can be a first electrode group Z1 and a second electrode group Z2, respectively. The gel portion 301 corresponding to the first electrode portion 201a in the first electrode group Z1 can be a first gel portion 3011, and the gel portion 301 corresponding to the first electrode portion 201a in the second electrode group Z2 can be a second gel portion 3012.
[0048] In the case where both the first gel portion 3011 and the second gel portion 3012 have a cylindrical lens 300a shape on the side facing away from the display panel 100, the height H1 of the cylindrical lens 300a presented by the first gel portion 3011 and the height H2 of the cylindrical lens 300a presented by the second gel portion 3012 can be different. Thus, for the same display screen, the three-dimensional display effect presented by the display area where the first gel portion 3011 is located and the display area where the second gel portion 3012 is located can also be different, thereby making the overall display effect of the screen more three-dimensional. Furthermore, in the three-dimensional display mode, the display device 000 can also cooperate with the AI large model screen prediction function to adjust the height H of the gel portion 301 in the corresponding area according to the content displayed on the screen, thereby improving the three-dimensional display effect of the display device 000.
[0049] Here, the height H of the cylindrical lens 300a presented by the gel portion 301 is positively correlated with the magnitude of the electric field between the first electrode portion 201a corresponding to the gel portion 301 and the adjacent second electrode portion 201b.
[0050] In other embodiments, the height H of the cylindrical lens 300a presented by the gel portion 301 may be negatively correlated with or have other corresponding relationships with the electric field between the first electrode portion 201a corresponding to the gel portion 301 and the adjacent second electrode portion 201b. This application does not impose any restrictions on this.
[0051] In some embodiments, such as Figure 9 As shown, when the same electrode group Z contains at least two first electrode portions 201a, the at least two first electrode portions 201a are arranged consecutively in the same electrode group Z and connected by an electrode connection portion 202. In this way, the at least two first electrode portions 201a in the same electrode group Z can be arranged in parallel, resulting in a simpler circuit and a simpler structure for the control electrode layer 200. This reduces the area of the control electrode layer 200 and minimizes its impact on light transmission and display effects.
[0052] In some embodiments, at least a portion of the control electrode layer 200 may be a conductive structure made of a transparent conductive material to further reduce the impact of the control electrode layer 200 on light transmission and display effects.
[0053] Please refer to Figure 11 , Figure 11This is a partial top view of another display device provided in this application embodiment. Both the first electrode portion 201a and the second electrode portion 201b can be strip-shaped electrode portions extending along the second direction Y. The control electrode layer 200 may further include: a first connecting portion 202a and a second connecting portion 202b disposed opposite to each other in the second direction Y. In the second direction Y, a plurality of first electrode portions 201a are located between the first connecting portion 202a and the second connecting portion 202b, and one end of each first electrode portion 201a is connected to the first connecting portion 202a, while the other end is spaced apart from the second connecting portion 202b. A plurality of second electrode portions 201b are located between the first connecting portion 202a and the second connecting portion 202b, and one end of each second electrode portion 201b is connected to the second connecting portion 202b, while the other end is spaced apart from the first connecting portion 202a.
[0054] The first connecting part 202a is used to receive the first electronic control signal K1 or the second electronic control signal K2, so that the first electrode part 201a can receive the first electronic control signal K1 or the second electronic control signal K2; the second connecting part 202b is used to receive the second electronic control signal K2, so that the second electrode part 201b can receive the second electronic control signal K2.
[0055] Here, as Figure 11 As shown, for the first electrode portion 201a and the second electrode portion 201b, in the first direction X, the width w1 of the first electrode portion 201a and the width w2 of the second electrode portion 201b can be greater than or equal to 5 micrometers and less than or equal to 10 micrometers (i.e., 5 micrometers to 10 micrometers); for the first connecting portion 202a and the second connecting portion 202b, in the second direction Y, the width w3 of the first connecting portion 202a and the width w4 of the second connecting portion 202b can be 5 micrometers to 10 micrometers. For example, the widths of the first electrode portion 201a, the second electrode portion 201b, the first connecting portion 202a, and the second connecting portion 202b can all be 8 micrometers. This avoids both excessively small widths leading to excessively high resistance and excessively large widths, thus saving space.
[0056] The widths w1-w4 can be the same or different; the widths w1 of different first electrode portions 201a can be the same or different (the same applies to w2-w4); the widths w1 of the same first electrode portion 201a at different positions can be the same or different (the same applies to w2-w4). This application does not impose any restrictions on these aspects. For example, when the widths w1-w4 are the same, the distribution of conductive material can be more uniform, the resistance difference is smaller, and the effect of adjusting the shape of the gel film 300 on the side facing away from the display panel 100 by the electronic control signal is also better.
[0057] In the first direction X, the first distance d1 between adjacent electrode portions can be 10 micrometers to 15 micrometers; in the second direction Y, the second distance d2 between the spaced second electrode portion 201b and the first connecting portion 202a, and the third distance d3 between the spaced first electrode portion 201a and the second connecting portion 202b can be 10 micrometers to 15 micrometers. For example, the first distance d1, the second distance d2, and the third distance d3 can all be 12 micrometers. In this way, when laying out the control electrode layer 200, it is possible to ensure safe distances between the first electrode portion 201a and the second electrode portion 201b, between the first electrode portion 201a and the second connecting portion 202b, and between the second electrode portion 201b and the first connecting portion 202a, so as to avoid short circuits or breakdowns, and also to further save space.
[0058] The distances d1-d3 can be the same or different; the first distance d1 between adjacent electrode portions at different positions can be the same or different (the same applies to d2-d3). This application does not impose any restrictions on this. For example, when the distances d1-d3 are the same, the conductive material distribution can be relatively uniform, and the gel film 300 can be divided into multiple gel portions 301 of similar size for switching the display modes of different areas in the display area of the display device and adjusting the display effect. Alternatively, please refer to... Figure 11 and Figure 12 , Figure 12This is a partial top view of another display device provided in an embodiment of this application. For the display area of the display device, the display area can be divided into a central display area 003 and an edge display area 004, with the edge display area 004 distributed around the central display area 003. For the control electrode layer 200, the first distance d1 within the central display area 003 can be smaller than the first distance d1 within the edge display area 004, and / or, the second distance d2 within the central display area 003 can be smaller than the second distance d2 within the edge display area 004, and / or, the third distance d3 within the central display area 003 can be smaller than the third distance d3 within the edge display area 004. Thus, the number of first electrode portions and second electrode portions arranged within the central display area 003 per unit area can be relatively large. Correspondingly, the portion of the gel film 300 located within the central display area 003 can be divided into a plurality of gel portions 301. Since viewers are generally more likely to view the central display area 003 than the edge display area 004, the central display area 003 contains a larger number of gel portions 301. When the display device is in 3D display mode, the height of these multiple gel portions 301 can be flexibly adjusted, resulting in a better 3D effect for the image displayed in the central display area 003. Simultaneously, the number of first and second electrode portions arranged per unit area in the edge display area 004 can be reduced, which helps to ensure a simpler overall structure of the control electrode layer 200 and reduces energy waste.
[0059] In some embodiments, please refer to Figure 13 , Figure 13 This is a partial structural schematic diagram of another display device provided in the embodiments of this application. The display device 000 may further include: an eye-tracking module 400, which can measure the viewing distance ds between the human eye and the display device 000.
[0060] The display device 000 is further configured to: determine the external height H of the lenticular lens 300a in three-dimensional display mode based on the viewing distance ds, and then determine the magnitude of the applied electronic control signal based on this external height H. The external height H is positively correlated with the viewing distance ds. For example, as shown... Figure 13 As shown in (a), in the vehicle-mounted display device, when the viewer adjusts the seat backward, the distance between the viewer and the display device 000 increases, that is, the viewing distance ds increases. At this time, the electronic control signal can be increased to increase the external height H of the cylindrical lens 300a; or, as shown in (a), Figure 13 As shown in (b), when the viewer adjusts the seat forward, the distance between the viewer and the display device 000 decreases, that is, the viewing distance ds decreases. At this time, the electronic control signal can be reduced to reduce the external height H of the cylindrical lens 300a.
[0061] In this way, a better 3D display effect can be presented to the viewer based on their position, avoiding the 3D display being unclear or overly prominent. Furthermore, while ensuring that the viewer can always enjoy a good 3D display effect in 3D mode, when the display device switches from 3D to 2D mode, the dizziness caused by the mode switch can be greatly reduced, improving the user experience.
[0062] In some embodiments, please refer to Figure 14 , Figure 14 This is a partial structural schematic diagram of another display device provided in the embodiments of this application. The human eye tracking module 400 can also be used to identify the direction of human eye rotation and determine the gaze area 00a and the non-gaze area 00b located outside the gaze area in the display area.
[0063] The display device 000 is configured to: apply a first electrical control signal to each first electrode portion 201a within the viewing area 00a, and apply a second electrical control signal to each second electrode portion 201b within the viewing area 00a, such that each gel portion 301 within the viewing area 00a has a cylindrical lens shape on the side facing away from the display panel 100, thereby placing the viewing area 00a in a three-dimensional display mode; and / or, apply a second electrical control signal to each first electrode portion 201a and each second electrode portion 201b within the non-viewing area 00b, such that each gel portion 301 within the non-viewing area 00b has a plane parallel to the display surface of the display panel 100 on the side facing away from the display panel 100, thereby placing the non-viewing area 00b in a two-dimensional display mode. That is, when the display area includes a first display partition 001 and a second display partition 002, the first display partition 001 can be the viewing area 00a, and the second display partition 002 can be the non-viewing area 00b.
[0064] For example, such as Figure 14 As shown, when the eye-tracking module 400 detects that the human eye is turning to the left, at least a portion of the left side of the display area of the display device 000 becomes the gaze area 00a. The gel portions 301 distributed within the gaze area 00a, on the side facing away from the display panel, can be shaped like a cylindrical lens. The gel portions 301 distributed within the non-gaze area 00b, on the side facing away from the display panel, can be parallel to the display surface of the display device. This allows the gaze area 00a to be switched to a 3D display mode in a timely manner, enabling the viewer to see a 3D display image. Simultaneously, the non-gaze area 00b can remain in a 2D display mode, helping to reduce energy waste. The display device 000 can also dynamically adjust parameters such as color temperature, color gamut, and sharpness to enhance image quality and improve the user experience.
[0065] In the embodiments of this application, such as Figure 14As shown, the eye-tracking module 400 may include a camera T. The camera T may be integrated into the display panel 100, and in a direction parallel to the display surface of the display panel 100, the camera T may be located in the light-transmitting area between adjacent pixels P. Alternatively, the camera may also be located on the side of the display panel 100 away from the gel film 300; this application does not impose any limitations on this.
[0066] In some embodiments, the display panel 100 may be a flexible display panel 100. Please refer to [reference needed]. Figure 15 , Figure 15 This is a partial structural schematic diagram of another display device provided in an embodiment of this application. In a three-dimensional display mode, at least a portion of the flexible display panel 100 may have protrusions 500 facing the gel film 300, and the area where the protrusions 500 are located overlaps with the orthographic projection of the cylindrical lens 300a on the display panel 100. In this way, the deformable protrusions 500 of the flexible display panel 100 can cooperate with the gel portion 301, making the presentation of the three-dimensional image more three-dimensional and realistic.
[0067] For example, a mechanical structure can be provided on the side of the flexible display panel 100 facing away from the gel film 300. This mechanical structure can cooperate with the display content and the state of the gel film 300 to push a portion of the flexible display panel 100 towards the gel film 300. The height of the protrusion 500 can be 2-3 millimeters. With the support of AI large model algorithms, the image is predicted, and the position and height of the protrusion 500 on the flexible display panel 100 are accurately determined, thereby achieving a more three-dimensional display effect. For example, 3D mountains can be displayed, making the undulations of the displayed mountains more realistic, or raised buttons can be displayed to help users perform blind operation.
[0068] The substrate of the flexible display panel 100 can be made of an elastic polymer material with high ductility and resistance to repeated deformation, such as polydimethylsiloxane (PDMS) or other flexible materials. During the stretching process of the flexible display panel 100, that is, when the protrusion 500 is formed, the position of pixel P will change accordingly. The display device can reallocate the pixel coordinates in real time through algorithms to ensure that the image content adapts to changes in screen size and avoids deformation or distortion.
[0069] In some embodiments, the display device 000 may further include: an image algorithm chip (not shown in the figure), which is used to extract image features of the display screen of the display panel 100 in real time in a three-dimensional display mode, and calculate the scene complexity factor (SCF) of the display screen in combination with a complexity evaluation model.
[0070] The display device 000 is configured to adjust the optical parameters of the lenticular lens 300a according to the scene complexity factor, thereby presenting a better display effect for different display images and reducing resource waste. Here, the optical parameters may include the lens focal length, grating angle, etc.
[0071] Naked-eye 3D display is viewpoint-based. Multi-viewpoint naked-eye 3D display can form a sequence of parallax images (frames) at different locations in space, so that 3D image pairs with parallax relationships can enter the left and right eyes of the user respectively, thus bringing the user a 3D experience.
[0072] In related technologies, Viewing Point Density (VPD) is typically set with fixed parameters, which can lead to inaccurate display or resource waste in complex scenarios such as high dynamic range images and multi-object interactions. For example, in traditional 3D display systems, viewpoint generation methods rely on a fixed number of viewpoint images and cannot be dynamically adjusted according to scene complexity, resulting in blurred edge areas or over-rendering of the central area.
[0073] Please refer to Figure 16 , Figure 16 This is an architecture diagram of a dynamic viewpoint density adjustment system provided in an embodiment of this application. This application provides a dynamic viewpoint density adjustment system based on an AI model, which can intelligently adjust viewpoint density by analyzing scene complexity in real time, thus solving display defects caused by fixed parameters. The system may include the following core modules: ① Scene Complexity Analysis Module: This module uses deep learning models (such as convolutional neural networks) to process input images in real time, extract scene features (such as object edges, texture complexity, and motion trajectories), and generate a complexity score. For example, in complex scenes (such as multi-person interaction and dynamic backgrounds), the model identifies high-complexity areas and marks them as requiring high-density viewpoint coverage. Figure 16 The AI scene analysis module is the core computing unit of the system. The image algorithm chip in the display device extracts multi-dimensional features of video frames in real time (such as spatial frequency, edge density, motion vector, and depth map dispersion). It combines the AI large model chip and algorithm to calculate a comprehensive scene complexity factor (SCF, with a value range of 0-1.0).
[0074] ② Dynamic Viewpoint Density Adjustment Module: Based on the complexity score, this module dynamically adjusts the viewpoint generation parameters. For example, in simple scenes (such as static single objects), it reduces viewpoint density to decrease computational resource consumption; in complex scenes, it increases viewpoint density to improve edge sharpness and stereoscopic effect. This module achieves adaptive parameter adjustment through optimization algorithms (such as gradient descent) to ensure efficient resource utilization. Figure 16The viewpoint density mapping strategy library serves as the system's brain, storing one or more non-linear mapping functions / lookup tables. It maps continuous SCF values to specific viewpoint density values (VPD) and viewpoint distribution patterns, outputting appropriate VPD values. For example, it can be set that "VPD is low when SCF < 0.3; VPD is high when SCF > 0.7". Here, the mapping strategy is programmable, allowing for customized optimization strategies based on different application scenarios (medical imaging, gaming, film and television), providing extremely high flexibility.
[0075] ③ Viewpoint Generation and Rendering Module: Combining multi-viewpoint image generation technology, this module generates high-quality viewpoint images using dynamic parameters. For example, it generates more viewpoints in complex areas to eliminate blurring through ray tracing or light field rendering methods, while reducing the number of viewpoints in simple areas to save computational resources. Figure 16 The adaptive viewpoint rendering engine receives VPD (View Point Rendering) instructions and dynamically adjusts the number of viewpoint images rendered. In low VPD mode, only key viewpoints can be rendered; in high VPD mode, more viewpoints can be activated. In some embodiments, foveated rendering technology can be combined to use higher density in the user's gaze area. Here, the adaptive viewpoint rendering engine is reconfigurable according to different application scenarios, and its rendering resources (computing power, memory) are dynamically allocated according to VPD instructions to improve energy efficiency.
[0076] ④ Dynamic Optical Adjustment Module: For any of the display devices provided in this application, the dynamic optical adjustment module can be used to receive VPD commands and physically adjust the parameters of optical components (such as lens focal length and grating angle) to match the viewpoint density output by the adaptive viewpoint rendering engine, ensuring that the optical system and image content work together. In this application embodiment, the optical component refers to the gel film. In related technologies, optical systems are usually static, and their optical parameters are fixed and cannot be adjusted. However, in this application embodiment, the optical parameters of the gel film can be flexibly adjusted, thereby enabling adaptive linkage between the optical system and the content, reducing crosstalk and waste at the source. Furthermore, dynamic adjustment of viewpoint density allows the display device to automatically adapt to ambient light, reducing glare and color shift, and effectively alleviating visual fatigue caused by prolonged use.
[0077] It should be noted that the fabrication process for forming a gel film on a display panel may include: Step S100: Dissolve 10% of PVC powder and 90% of dibutyl phthalate (DBP) in tetrahydrofuran (THF).
[0078] Step S200: Spin-coat the above solution onto the side of the control electrode layer away from the display panel.
[0079] Step S300: After THF evaporates, a gel film is formed.
[0080] Here, in the direction perpendicular to the display surface of the display device 000, the thickness of the gel film 300 can be 20-30 micrometers. For example, the thickness of the gel film 300 can be 25 micrometers. This avoids the image quality degradation caused by excessive thickness of the gel film 300 in the two-dimensional display mode, while also preventing the gel film 300 from being too thin, ensuring that the gel film 300 can generate sufficient external height H through deformation, so that the display device has a better stereoscopic display effect in the three-dimensional display mode.
[0081] Furthermore, when the gel membrane 300 is a flexible membrane layer made of polyvinyl chloride (PVC), PVC has a low cost and is easy to prepare. Its structure and process are relatively simple, and the resulting gel membrane 300 has good flexibility and light transmittance. Therefore, it has significant advantages in terms of process manufacturing and cost.
[0082] like Figure 17 As shown, Figure 17 This is a partial structural schematic diagram of another display device provided in an embodiment of this application. The display device 000 may further include: a flexible glass substrate 600, which is located on the side of the gel film 300 facing away from the display panel 100, for protecting the gel film 300 and other structures while allowing light to pass through, and preventing the flexible glass substrate 600 from restricting the deformation of the gel film 300. The thickness of the glass substrate can be 0.1 mm to 0.3 mm in the direction perpendicular to the display surface of the display device 000. For example, the thickness of the glass substrate can be 0.15 mm.
[0083] Please refer to Figure 18 , Figure 18 This is a partial structural schematic diagram of another display device provided in an embodiment of this application. This application also provides a display device 000, which may include: a display panel 100 and a lens film 700, the lens film being located on the display side of the display panel 100. The side of the lens film 700 facing away from the display panel 100 may have multiple columnar lenses 700a or hemispherical lenses 700a arranged in an array, used to enable the display device 000 to present a three-dimensional display effect. The lens film 700 may be a flexible light-transmitting film layer made of polyvinyl chloride (PVC) material.
[0084] It should be noted that the display panel 100 in any embodiment of this application can be an OLED display panel 100 that uses organic light-emitting diodes (OLEDs) to achieve the display function, or it can be a QLED display panel 100 that uses quantum dot light-emitting diodes (QLEDs) to achieve the display function, or it can be a QD-OLED display panel 100 that uses quantum dot organic light-emitting diodes (QD-OLEDs) to achieve the display function, or it can be a liquid crystal display (LCD). The display panel 100 can be a curved display panel 100. This application does not impose any limitations in this regard.
[0085] In summary, the display device provided in this application includes a display panel, a control electrode layer, and a gel film. The display device is configured to control the shape of the gel film facing away from the display panel by applying an electrical control signal to the control electrode layer, thereby enabling the display area of the display device to be in a two-dimensional display mode and / or a three-dimensional display mode. In the two-dimensional display mode, the side of the gel film facing away from the display panel is parallel to the display surface of the display panel; in the three-dimensional display mode, the side of the gel film facing away from the display panel has multiple cylindrical lenses. When the side of the gel film facing away from the display panel is parallel to the display surface of the display panel, the gel film has less influence on the transmitted light. Therefore, even if a gel film is provided on the light-emitting side of the display panel when the display device is in two-dimensional display mode, the gel film has less influence on the clarity, brightness, and color of the displayed image, thus avoiding image quality degradation. Furthermore, by applying an electrical control signal to the control electrode layer to form an electric field and adjusting the shape of the gel film facing away from the display panel, the display mode of the display device can be adjusted, making the switching between 2D and 3D display modes more flexible.
[0086] This application also provides a vehicle that includes the display device 000 described in any of the above embodiments. The display device 000 can be an instrument panel screen, central control screen, passenger-side screen, or rear-seat screen, etc. It should be noted that the composition and function of the display device 000 are completely identical to those of the display device 000 provided in the above embodiments of this application, and will not be repeated here. This vehicle, utilizing the display device 000, can adapt to the different needs of drivers and passengers, ensuring driving safety while also enhancing the user experience.
[0087] For example, in the vehicle provided in this application embodiment, after the vehicle is powered on, the onboard camera and related sensors (such as light sensors, vehicle speed sensors, etc.) begin to work, and the display device lights up. Drivers and passengers can select to enable or disable 3D display through the settings options on the screen (such as the vehicle settings menu), and can also enable 3D enhanced display depending on the usage scenario. Under 3D enhanced display, refer to... Figure 10 The display device can be adjusted by changing the height H of different gel portions 301, and / or, referring to... Figure 15 The display device can enhance the stereoscopic effect of 3D display by cooperating with the protrusions 500 of the flexible display panel 100 through the gel film 300. For example, when the vehicle is stationary and the display screen is playing a movie, the 3D enhancement mode can be activated to make the displayed image more three-dimensional. When the vehicle is in reverse gear, the display device can automatically display the rearview camera image in 3D, enhancing the driver's distance perception and improving driving safety.
[0088] Simultaneously, based on the vehicle's overall AI model and user scenarios, it can proactively recommend switching between 2D and 3D display effects to achieve a more intelligent in-cabin visual experience. For example, Figure 19 As shown, Figure 19 This is a schematic diagram of a display device display selection pop-up window provided in an embodiment of this application. The pop-up window allows drivers and passengers to select a switching mode. When the 2D / 3D switchable mode is enabled, the vehicle camera or the camera inside the display device can be used to identify the direction of eye movement and viewing distance of the drivers and passengers, and adjust the shape of the gel film accordingly in combination with the content displayed on the screen. This eliminates the need for drivers and passengers to frequently switch between 2D / 3D display modes and can effectively avoid eye fatigue while driving.
[0089] like Figure 14 As shown, when the camera detects changes in a passenger's eye movement, such as when the eye moves to the left, the software program within the screen can control the deformation of the gel film. For example, the voltage in the left area of the display device can be increased to highlight the 3D effect in the gaze area 00a. In this way, the display device can adjust the visual effect and viewing angle for different viewers when achieving naked-eye 3D display. Furthermore, during vehicle movement, affected by factors such as vehicle bumps, the deformation of the gel film can be adjusted in real time according to changes in the eye movement as the human eye continuously focuses on the display device. This can alleviate dizziness, visual fatigue, and other problems, thereby improving driving safety.
[0090] It should be noted that the dimensions of layers and regions may be exaggerated in the accompanying drawings for clarity. Furthermore, it is understood that when an element or layer is referred to as being "on" another element or layer, it can be directly on the other element, or there may be intermediate layers. Additionally, it is understood that when an element or layer is referred to as being "below" another element or layer, it can be directly below the other element, or there may be more than one intermediate layer or element. Furthermore, it is also understood that when a layer or element is referred to as being "between" two layers or two elements, it can be the only layer between the two layers or two elements, or there may be more than one intermediate layer or element. Similar reference numerals throughout indicate similar elements.
[0091] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.
[0092] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
