[0002] The current LED display screen is usually a flat-panel display, and the entire display screen is displayed on the entire flat screen, such as a bus station notice board, showing a static or dynamic image display, and the display effect lacks a three-dimensional visual effect. In response to this, there are also LED display screens that are set to be curved, which can improve the display effect to a certain extent.

[0003] However, the current display solution is to transmit the video image 1:1 to the flexible curved LED screen for 100% full layout, which has high requirements on the resolution-related dimensions of the video image. Although there are technical processing methods such as stretching, enlarging or reducing in this direction, the image is deformed due to the horizontal and vertical stretching of the image in different proportions, thus affecting the output quality of the video image.

[0027] Further, the step of identifying voxel boundary information on the pattern point cloud data through the current flexible state of the LED screen, and determining the cross-section of independent position and size on the pattern display surface based on the matching of the voxel boundary information and the pattern display surface includes:

[0028] By using a preset absolute horizontal line, determining the angle information of the LED screen in the current flexible state, whether the angle is greater than or less than 0°, and using the angle information to identify the voxel boundary information on the pattern point cloud data;

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.

[0054] Reference Figure 1-2 , which is a flow chart of a pattern display method of a full-angle flexible LED screen proposed by the present invention, comprising the following steps:

[0055] S1, identifying the flexibility state of the LED screen, and importing the flexibility state into a voxel bounding box model;

[0056] S2, using the voxel bounding box model, marking each voxel block of the LED screen in the current flexible state, wherein the voxel block is the area where the LED screen outputs a pattern;

[0057] S3, forming a one-to-one corresponding display interface for each of the voxel blocks through a voxel bounding box model, and outputting the acquired pattern data through the display interface, and in the process of outputting the pattern data, outputting each sub-pattern data based on the position and size of the voxel block, each sub-pattern data is data obtained after the pattern data is segmented according to the voxel block;

[0058] The method of labeling each voxel block of the LED screen in the current flexible state with the voxel bounding box model includes:

[0059] S21, creating a three-dimensional space coordinate system, and adding the modeling of the LED screen in the current flexible state to the three-dimensional space coordinate system, and identifying the pattern display surface of the LED screen in the three-dimensional space coordinate system;

[0060] S22, calculating pattern point cloud data of the pattern display surface in the three-dimensional space coordinate system by using a bounding box algorithm;

[0061] S23, identifying voxel boundary information on the pattern point cloud data through the current flexible state of the LED screen, and determining a cross section of independent position and size on the pattern display surface based on the matching of the voxel boundary information and the pattern display surface;

[0062] S24, marking each voxel block corresponding to the cross section in the three-dimensional space coordinate system through the cross sections of independent positions and sizes on the pattern display surface.

[0063] For S1, specifically:

[0064] The steps of identifying the flexible state of the LED screen include:

[0065] Obtaining flexibility changes of the deformation sensing module;

[0066] The change numerical value calculation is performed based on the flexibility change to obtain the flexibility state of the LED screen, wherein the deformation sensing module is a module that fits tightly to the LED screen.

[0067] The step of obtaining the flexibility change of the deformation sensing module includes:

[0068] A gyroscope matrix on the deformation sensing module is identified to determine the change values ​​between the gyroscopes in the gyroscope matrix.

[0069] In the specific implementation process: the deformation sensing module is a device that fits tightly on the LED screen, which can sense the bending or deformation of the LED screen. When the LED screen bends or deforms, the deformation sensing module will change accordingly, and these changes reflect the flexibility of the LED screen. The device will obtain the change data of the deformation sensing module, and its value represents the flexibility of the LED screen, that is, the degree of bending, bending direction and other information. The deformation sensing module is equipped with a gyroscope matrix, which is an array composed of multiple tiny gyroscopes. The gyroscope is a sensor that can sense the rotation or tilt of an object. Therefore, the gyroscope matrix can sense the bending or deformation of the LED screen in all directions. When the LED screen bends or deforms, each gyroscope in the gyroscope matrix will produce different change values. The device will analyze the change values ​​to determine the degree of bending or deformation of the LED screen in all directions.

[0070] After the step of S1, specifically:

[0071] After the step of importing the flexible state into the voxel bounding box model, the method further comprises:

[0072] Retrieve the default LED screen status preset in the voxel bounding box;

[0073] Compare the default LED screen state with the current flexible state of the LED screen and calculate the difference value;

[0074] The default LED screen state in the voxel bounding box is modified based on the difference value to make it consistent with the flexible state corresponding to the current LED screen, and the LED screen modeling in the current flexible state is generated.

[0075] In the specific implementation process: a default LED screen state is preset in the voxel bounding box model. This state represents the standard state of the LED screen when it is not bent or deformed. When the device starts to process the pattern display of the flexible LED screen, it first calls this default state as a reference. The device will compare the currently identified flexible state with the default state numerically. Through the comparison, the device can calculate the difference between the two. This difference represents the change in the LED screen from the default state to the current flexible state. According to the calculated difference, the device will modify the default LED screen state in the voxel bounding box. The purpose of the modification is to make the LED screen state in the voxel bounding box model consistent with the current actual LED screen's flexible state. After the modification is completed, the device will generate an LED screen modeling corresponding to the current flexible state. This modeling will be used for subsequent pattern display processing.

[0076] For S21, specifically:

[0077] The step of identifying the pattern display surface of the LED screen in the three-dimensional space coordinate system comprises:

[0078] Get the position information of the gyroscope matrix output preset in the LED screen;

[0079] The position information of each of the above is marked in the three-dimensional space coordinate system, so that the voxel bounding box model can identify the pattern display surface of the LED screen in the three-dimensional space coordinate system.

[0080] In the specific implementation process: Based on the gyroscope matrix mentioned above, the position and posture of the LED screen in space can be sensed in real time. The gyroscope matrix will output position information, which describes the specific position and direction of the LED screen in three-dimensional space. The voxel bounding box model is a model used to represent and process the shape and posture of objects in three-dimensional space. By marking the position information of the LED screen in the three-dimensional space coordinate system, the device can use the voxel bounding box model to identify the specific shape and posture of the LED screen in space, especially the position and direction of its pattern display surface.

[0081] For S22, specifically:

[0082] Determine the bounding box type:

[0083] When processing the pattern display surface of the LED screen, usually choose the axis-aligned bounding box (AABB) or oriented bounding box (OBB) and other types. These bounding box types have their own advantages and disadvantages, and the specific choice depends on the needs of the application scenario.

[0084] Construct the bounding box:

[0085] According to the position and posture of the LED screen in the three-dimensional space coordinate system (obtained through the gyroscope matrix), a bounding box that can completely surround the pattern display surface is constructed. The boundary of this bounding box should closely fit the outer contour of the pattern display surface to minimize unnecessary space occupation.

[0086] Calculate pattern point cloud data:

[0087] After the bounding box is built, the device will generate point cloud data of the pattern inside the bounding box according to the requirements of the pattern design and the display characteristics of the LED screen. The point cloud data represents the specific position and shape of the pattern in three-dimensional space.

[0088] When calculating point cloud data, factors such as pattern resolution, display effect, and computational efficiency need to be considered. Usually, the device will use certain sampling strategies (such as uniform sampling, importance sampling, etc.) to generate point cloud data to ensure a balance between pattern display effect and computational efficiency.

[0089] For S23, specifically:

[0090] The step of identifying voxel boundary information on the pattern point cloud data through the current flexible state of the LED screen, and determining cross sections of independent positions and sizes on the pattern display surface based on the matching of the voxel boundary information and the pattern display surface, comprises:

[0091] By using a preset absolute horizontal line, determining the angle information of the LED screen in the current flexible state, whether the angle is greater than or less than 0°, and using the angle information to identify the voxel boundary information on the pattern point cloud data;

[0092] The voxel boundary information is matched with the pattern display surface to obtain a plurality of cross sections with independent positions and sizes where folded corner information appears.

[0093] In specific implementation: the device first presets an absolute horizontal line as a reference, and then the device determines whether the angle of the LED screen is greater than or less than 0° in the current flexible state. This step is to identify whether there is a fold or bend on the LED screen, and the specific direction of the fold. The device identifies the fold information on the LED screen, that is, identifies the voxel boundary on the pattern point cloud data. Voxel boundary refers to the boundary line in the pattern point cloud caused by the bending or deformation of the LED screen. The boundary line divides the pattern point cloud into different areas, each area corresponding to an independent position or size of the cross section on the LED screen. The device will match the identified voxel boundary information with the pattern display surface. The purpose of this step is to determine the independent position and size of the cross section caused by the bending or deformation of the LED screen. Through matching, the device can accurately identify which parts of the pattern display surface are independent cross sections caused by the fold, as well as the specific position and size of these cross sections. Finally, based on the matching results of voxel boundary information and pattern display surface, the device will determine the cross-sections with independent positions and sizes on the pattern display surface. These cross-sections are the basic units when the pattern is displayed on the LED screen. Their positions and sizes determine the specific display effects of the pattern on the LED screen.

[0094] For S24, specifically:

[0095] A voxel block is generated based on the one-to-one correspondence of the cross sections, and the minimum size of the voxel block is 1 pixel.

[0096] For S3, specifically:

[0097] A one-to-one display interface is created by forming each voxel block through a voxel bounding box model, and the acquired pattern data is output by the display interface. In the process of outputting the pattern data, each sub-pattern data is output one-to-one based on the position and size of the voxel block, and each sub-pattern data is the data obtained after the pattern data is divided according to the voxel block.

[0098] In specific implementation:

[0099] In the voxel bounding box model, each voxel block represents an independent display unit. The device creates corresponding display interfaces based on these voxel blocks to ensure that each voxel block has a corresponding display interface.

[0100] The display interface is responsible for outputting the pattern data related to its corresponding voxel block. The data is extracted from the original pattern data and is used to display it at a specific position on the LED screen.

[0101] When outputting pattern data, the device will consider the specific position and size of each voxel block. The output sub-pattern data will closely match the position and size of the voxel block, ensuring that the pattern is displayed accurately on the LED screen.

[0102] The sub-pattern data is obtained by segmenting the original pattern data. The device will segment the original pattern data into multiple sub-pattern data according to the position and size of the voxel block, and each sub-pattern data corresponds to a voxel block.

[0103] In this way, the device can ensure that the pattern is displayed accurately on the flexible LED screen. Even if the LED screen is bent or deformed, the pattern can closely fit the shape of the screen and present the ideal display effect.
