[0045] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0046] The LED screen panoramic display method based on naked-eye 3D technology of the embodiment of the present invention can be executed by a local processor of the LED screen or a cloud processor connected to the LED screen.

[0047] Reference Figure 1 The embodiment of the present application provides a method for panoramic display of an LED screen based on naked-eye 3D technology. An electrochromic film layer is arranged in front of the LED screen. The electrochromic film layer includes a plurality of electrochromic units arranged in a preset arrangement. Each of the electrochromic units can be independently controlled to change color. The method includes:

[0048] S1. Obtain the format type of the content to be played on the LED screen;

[0049] S2. According to the format type and the preset format-electrochromic film state correspondence, determining the state of the electrochromic film layer adaptation, wherein the state includes the target transmittance of each electrochromic unit;

[0050] S3. According to the adaptation state of the electrochromic film layer, voltages are applied to the electrochromic units respectively, so as to control the electrochromic units to adjust to the corresponding target transmittance.

[0051] In this embodiment, the above-mentioned naked-eye 3D technology refers to a technology that allows direct viewing of stereoscopic images without wearing any auxiliary equipment (such as 3D glasses). The above-mentioned LED screen is a light-emitting diode (Light-Emitting Diode) display screen, an electronic device used to display playback capacitors. The above-mentioned electrochromic film layer is arranged in front of the LED screen. Specifically, the front refers to the side close to the viewer. The distance between the electrochromic film layer and the LED screen is installed according to a pre-set distance, which can usually refer to the distance between the slit grating and the LED screen in the 3D display technology. The above-mentioned electrochromic film layer is a thin film material that can change its transmittance according to the change of the applied voltage, and is usually composed of an electrochromic material, an electrolyte layer, an ion storage layer and a transparent conductive substrate layer. The above-mentioned electrochromic unit is the smallest unit on the electrochromic film layer that can independently control the color change. The electrochromic unit can be formed on the electrochromic film layer by the segmentation technology in the prior art, for example, the transparent conductive substrate layer is segmented longitudinally, transversely or crisscrossed, and the voltage of each electrochromic unit is further controlled by the controller, so that each electrochromic unit can be independently controlled. The embodiment of the present invention briefly introduces the specific electrochromic film layer and the realization process of the electrochromic unit. Since the manufacturing process is not the main innovation of the embodiment of the present invention, it will not be repeated here.

[0052] In the above step S1, firstly, the content information to be played by the LED screen is detected or received, and its format type is identified. Specifically, this can be achieved by parsing the metadata of the content file, checking the file extension, or using other content identification technologies; or an identification character corresponding to a preset format type can be added to the produced playback content, and the format type of the content to be played by the LED screen can be determined by parsing the identification character.

[0053] In the above step S2, according to the identified format type, a preset format-electrochromic film state correspondence table or database is searched to determine the state that the electrochromic film layer corresponding to the format should reach. This state is expressed in the form of the target transmittance of each electrochromic unit, which is used to provide a basis for the voltage application process in the subsequent steps.

[0054] In the above step S3, the voltage value to be applied to each electrochromic unit is determined according to the determined target transmittance. Specifically, for the electrochromic unit, there is a preset transmittance-voltage correspondence table, and the corresponding voltage can be found according to the transmittance. Then, the controller applies corresponding voltages to each electrochromic unit to cause a color change reaction and adjust it to a predetermined transmittance. In this way, the entire electrochromic film layer presents optical properties that match the format of the content to be played. Thus, for example, a grating with alternating light and dark, a fully transparent unobstructed state, and a striped or frame-like structure of a preset format can be formed.

[0055] The LED screen panoramic display method based on naked-eye 3D technology in this embodiment realizes adaptive display of content of different formats through the dynamic adjustment capability of the electrochromic film layer, so that it can adapt to the playback content of multiple formats, solving the problem of poor content format compatibility of traditional naked-eye 3D display devices.

[0056] In one embodiment, the step S2 of determining the state of the electrochromic film layer adaptation according to the format type and the preset format-electrochromic film layer state correspondence includes:

[0057] S201, if the format type is a parallax image, determining that the state of the corresponding electrochromic film layer is a grating state according to a preset format-electrochromic film layer state correspondence relationship;

[0058] S202 . According to the grating light and dark stripes corresponding to the parallax image, the target transmittance of each of the electrochromic units is set to a transmittance matching the corresponding grating light and dark stripes.

[0059] In this embodiment, in the above step S201, it is first identified that the content to be played by the LED screen is in the parallax image format, and then the state of the electrochromic film layer is determined to be the grating state according to the preset format-electrochromic film layer state correspondence. The above parallax image is an image for naked-eye 3D display, including a left-eye sub-image corresponding to the left-eye perspective and a right-eye sub-image corresponding to the right-eye perspective. By using the principle of the visual difference between the left and right eyes of the human eye, a grating plate with periodic light and dark stripes and slits is placed in front of the LED screen, so that the left-eye sub-image and the right-eye sub-image enter the corresponding eyes respectively, so that the viewer can feel the 3D stereoscopic effect without glasses. The above grating state is a specific state in which the electrochromic film layer is configured to simulate the grating effect.

[0060] In the above step S202, the above grating light and dark stripes are light and dark stripes formed on the electrochromic film layer in the grating state, and the arrangement and width of these stripes are configured to realize the grating that can realize the 3D effect of the above parallax image in the human eye. Analyze the grating light and dark stripes corresponding to the parallax image, and calculate the target transmittance that each electrochromic unit should achieve. The unit corresponding to the bright stripes should have a higher transmittance to allow more light to pass through; while the unit corresponding to the dark stripes should have a lower transmittance to block part of the light. Therefore, the controller can apply corresponding voltages to each electrochromic unit to adjust it to a predetermined transmittance, so that the electrochromic film layer forms grating light and dark stripes corresponding to the parallax image.

[0061] This embodiment recognizes the parallax image and determines the corresponding grating light and dark stripes, and then uses the independent control characteristics of each unit of the electrochromic film layer to adjust each electrochromic unit to a transmittance that matches the grating light and dark stripes, thereby simulating the grating effect and realizing naked-eye 3D display.

[0062] In a specific embodiment, the step S202 of setting the target transmittance of each electrochromic unit to a transmittance matching the corresponding grating light and dark stripes according to the grating light and dark stripes corresponding to the parallax image includes:

[0063] S2021, obtaining preset adaptive grating parameters corresponding to the parallax image, wherein the grating parameters include grating stripe width and spacing;

[0064] S2022, determining the position of each electrochromic unit corresponding to the grating stripe width, taking each electrochromic unit corresponding to the grating stripe width as a first electrochromic unit, and setting the target transmittance corresponding to the first electrochromic unit to the minimum transmittance;

[0065] S2023: Use the remaining electrochromic unit as the second electrochromic unit, and set the target transmittance corresponding to the second electrochromic unit to the maximum transmittance.

[0066] In this embodiment, in the above step S2021, the above preset adaptive grating parameters are a set of preset grating parameters that match a specific parallax image, and the grating parameters define key features such as the width and spacing of the grating stripes. The width of the grating stripes refers to the width of the dark stripes themselves, and the spacing refers to the distance between two adjacent dark stripes. The above preset adaptive grating parameters are parameters pre-set by the user and pre-stored in the local database, or pre-stored in the cloud and obtained through network download; they can also be parameters manually input by the user.

[0067] In the above step S2022, the above first electrochromic unit is an electrochromic unit corresponding to the width of the grating stripes. Specifically, according to the width and spacing of the grating stripes, the position of the electrochromic unit corresponding to the width of each grating stripe is calculated. For each first electrochromic unit, its target transmittance is set to the minimum transmittance to form a dark stripe that blocks the passage of light.

[0068] In the above step S2023, the above-mentioned second electrochromic unit is an electrochromic unit other than the first electrochromic unit, and needs to be set to the highest transmittance to form bright stripes of the grating, allowing a large amount of light to pass through, so that the left-eye sub-image corresponding to the left-eye perspective and the right-eye sub-image corresponding to the right-eye perspective can be transmitted to the viewer's left eye or right eye in different directions.

[0069] In one embodiment, the step S2 of determining the state of the electrochromic film layer adaptation according to the format type and the preset format-electrochromic film layer state correspondence includes:

[0070] S211, if the format type is a 2D image, determining that the state of the corresponding electrochromic film layer is a fully transparent state according to a preset format-electrochromic film layer state correspondence relationship;

[0071] S212, setting the target transmittance of each electrochromic unit to a maximum transmittance.

[0072] In this embodiment, in the above step S211, it is first determined whether the image format input into the display device is a 2D image, and the above 2D image is an image with ordinary visual effects. The above full-transmission state is a transmittance state of the electrochromic film layer, at which the maximum amount of light is allowed to pass through, and each electrochromic unit exhibits a high degree of transparency. Since it is not necessary to form a grating or strip frame for a 2D image that does not require a three-dimensional effect, the electrochromic film layer should be in a full-transmission state to maximize the original brightness and clarity of the image.

[0073] In the above step S212, the above maximum transmittance is the maximum transmittance that allows light to pass through, so that the electrochromic film layer is in a transparent state, thereby avoiding any unnecessary visual interference or brightness loss to the 2D image.

[0074] This embodiment makes the electrochromic film layer in a fully transparent state to maintain the original brightness, contrast and clarity of the 2D image, ensuring that viewers get the best visual experience. Compared with mature 2D playback content, the production of naked-eye 3D content is more complicated and the content is scarce. This embodiment makes the LED screen compatible with 3D and 2D playback content, thereby greatly improving the commercial use value of the LED screen.

[0075] In one embodiment, the step S2 of determining the state of the electrochromic film layer adaptation according to the format type and the preset format-electrochromic film layer state correspondence includes:

[0076] S221, if the format type is a perspective image, determining that the state of the corresponding electrochromic film layer is a bar frame state according to a preset format-electrochromic film layer state correspondence relationship;

[0077] S222, selecting some electrochromic units from the electrochromic film layer according to a preset rule, and setting the transmittance of the selected part of the electrochromic units to the minimum transmittance, so as to form dark stripes on the content to be played on the LED screen.

[0078] In this embodiment, in the above step S221, the above perspective image is an image that makes the viewer feel the 3D stereoscopic effect by adding a specific border or frame to the video content, using visual illusion and image processing technology. It is actually still a 2D image, but the image processing creativity makes the flat image have a three-dimensional sense. The above stripe frame state is a specific state of the electrochromic film layer, in which the electrochromic film layer is configured to present a lower transmittance in a specific area (such as a stripe frame-shaped area), and maintain a higher transmittance or full transmittance in other areas to form a visual stripe frame effect.

[0079] In the above step S222, the above minimum transmittance is the transmittance that allows the least light to pass through, so as to form a strip frame. The above preset rules are specific requirements or algorithms for selecting some electrochromic units from the electrochromic film layer, wherein the specific requirements may be preset, for example, for a certain perspective image, it is preset to select the entire preset column of electrochromic units at the horizontal one-third and the vertical two-thirds of the image (and further, in the entire preset column of electrochromic units, several rows of electrochromic units are not selected), or select the entire preset row and the entire preset column of electrochromic units at the preset positions around the image, etc.; the algorithm may be based on the recognition of image content, by identifying the shape, position and other factors of the preset feature content in the image to generate a dark strip frame, and then guide the selection of the electrochromic unit at the position corresponding to the dark strip frame. The preset feature content can be predefined by humans and set for identification, such as a protruding head, a flying bullet, etc.

[0080] In this embodiment, by forming a dark frame on the display content, in conjunction with the corresponding perspective image, an out-of-frame effect of the elements in the perspective image can be created, thereby enhancing the naked-eye 3D visual effect of the perspective image, allowing the viewer to more clearly perceive the layering and spatial sense of the image. The electrochromic unit can flexibly adjust the width and position according to preset rules, thereby providing a high degree of flexibility and wide applicability.

[0081] In a specific embodiment, the step S222 of selecting some electrochromic units from the electrochromic film layer according to a preset rule and setting the transmittance of the selected electrochromic units to the minimum transmittance to form a dark frame on the content to be played on the LED screen includes:

[0082] S2221, obtaining coordinates of a predefined frame in the perspective image; the predefined frame is used to enhance the stereoscopic effect when displaying naked-eye 3D content;

[0083] S2222, selecting an electrochromic unit corresponding to the predefined bar coordinates from the electrochromic film layer as a third electrochromic unit, setting the transmittance of the third electrochromic unit to the lowest transmittance, and setting the transmittance of the remaining electrochromic units to the highest transmittance.

[0084] In this embodiment, in the above step S2221, the above predefined frame coordinates are the position coordinates of a rectangular or other shape area pre-set in the perspective image for a specific visual effect (such as enhancing the stereoscopic effect). The coordinates of the predefined frame can be described by the producer of the perspective image when producing it, or the predefined frame coordinates can be added to the image of a specific frame, so that the coordinates of the predefined frame can be identified by image recognition.

[0085] In the above step S2222, according to the coordinates of the predefined stripe, the electrochromic unit set corresponding to the coordinates is found in the electrochromic film layer, and the electrochromic unit set is marked as the third electrochromic unit. Subsequently, by applying a specific voltage or current signal to the third electrochromic unit, its transmittance is quickly adjusted to the lowest transmittance state to achieve the display effect of the dark stripe. At the same time, the transmittance of all remaining electrochromic units that are not selected as the third electrochromic unit is set to the highest transmittance to maintain its original transparent state for displaying the display content in the perspective image.

[0086] In this embodiment, the strips are formed by an electrochromic film layer, and the position, shape and size of the dark strips can be flexibly adjusted through preset parameters or user input, thereby avoiding frame-by-frame modification of the perspective picture and greatly reducing the production cost of naked-eye 3D playback content.

[0087] In one embodiment, after the step S3 of applying voltage to each electrochromic unit according to the adapted state of the electrochromic film layer to control each electrochromic unit to adjust to the corresponding target transmittance, the method further comprises:

[0088] S4, determining whether the LED screen switches to the content to be played;

[0089] S5: If yes, determine whether the format type of the content to be played has changed;

[0090] If yes, then the step S2 of determining the adapted state of the electrochromic film layer according to the format type and the preset format-electrochromic film layer state correspondence is executed.

[0091] In this embodiment, the state of the electrochromic film layer is automatically adjusted according to the changes in the content by dynamically monitoring the changes in the content played by the LED screen, so as to ensure that the display effect matches the content type. By judging in real time whether the content is switched and whether the format type is changed, the state of the electrochromic film layer is adjusted in time, thereby realizing intelligent adaptation to content of different formats and types, and improving the flexibility and response speed of the LED screen.

[0092] In the above step S4, it is achieved by detecting whether the content currently played by the LED screen is different from the content to be played. Specifically, it can be achieved by comparing the identifier of the currently played content (such as file name, URL or content ID) with the identifier of the content to be played.

[0093] In the above step S5, if content switching is detected, the format type of the content to be played is further obtained and compared with the format type of the content currently played. If they are the same, there is no need to switch the state of the electrochromic film layer adaptation. If they are different, return to step S2, adjust the state of the electrochromic film layer adaptation, re-determine the adaptation state that the electrochromic film layer should be in, and further determine which areas of the electrochromic unit need to adjust their transmittance, and the target transmittance value that should be adjusted, and apply corresponding voltages to each electrochromic unit to control them to adjust to the new target transmittance.
