The current progress is calculated according to the linear interpolation algorithm, and then the current progress point is calculated through the start coordinates and end coordinates.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Figure 1 This invention provides a flowchart of an LED text effect control method. This invention is applicable to situations where text is dynamically rendered on an LED screen, particularly LEDs. The method can be executed by an LED text effect control device, which can be implemented in hardware and / or software and can be configured in a server. Figure 1 As shown, the method includes: S110, responding to the interactive interface to obtain a text movement request; the text movement request includes text content and corresponding special effects data; the special effects data includes movement direction, frame rate, movement parameters, total movement time, and target coordinates.

[0019] The interactive interface is used to interact with the user and obtain the user's input text dynamic display request to be displayed on the target display screen, i.e., the LED screen. The text movement request is the moving text requirement for this dynamic rendering, which may include the text content to be dynamically displayed. The text content can be at least one character. The special effect data corresponding to the text content can be the movement direction corresponding to the text content. The movement direction can be the movement of the text content from left to right, from right to left, from top to bottom, or from bottom to top. The frame rate refers to the number of times the screen refreshes per second. The movement parameter is the parameter that controls the movement speed. The total movement time is the total time required for a single display area to move from the initial position to the target position. The target position is the position where the special effect ends.

[0020] Specifically, in response to user input in the interactive interface, it can obtain the text movement request to be dynamically displayed on the LED screen, which may include the text content to be dynamically moved, as well as special effects data such as the movement direction corresponding to the text content.

[0021] It should be noted that the input operation can be to obtain the user's one-to-one input to obtain the corresponding text movement request, or to obtain the user's input document to be displayed, and dynamically extract the document to be displayed to obtain the corresponding text movement request, etc. Relevant technicians can set the input operation according to actual needs, as long as it can obtain the text movement request. The embodiments of the present invention do not specifically limit the input data format corresponding to the input operation.

[0022] S120. Determine at least one display area based on the text content and the target display screen data.

[0023] The target display screen data refers to the screen data corresponding to the target display screen, which may include the screen width and screen height of the LED screen. The screen width and screen height are represented in pixels, for example, the LED screen width is 192 pixels and the height is 32 pixels, or the LED screen width is 32 pixels and the height is 192 pixels. The display area is the dot matrix pixel data corresponding to each character in the text content. The width and height of the dot matrix pixel data can be preset by the user. The display area may also include the initial coordinates of each character on the LED screen.

[0024] Specifically, at least one character in the text content is identified, and the character is converted into pixel data to obtain the display area corresponding to each character. The initial coordinates of at least one display area are determined according to the screen width and screen height corresponding to the target display screen data.

[0025] Optionally, at least one display area is determined based on the text content and the target display screen data, including: The text content is split into text segments to obtain at least one character and a text sequence; Based on the target display screen data and the direction of movement, the text is transformed into a pixel matrix to obtain the dot matrix pixel data corresponding to the text as the display area. The display area is sorted according to the text order to obtain the text pixel set; The number of displays is determined based on the target display screen data, the direction of movement, and the ratio between display areas; The starting coordinates of the display area are determined based on the text order, the number of texts displayed, and the target screen data.

[0026] Among them, the text order refers to the arrangement order of the characters in the text content; the dot matrix pixel data is the data corresponding to the screen height, and the text width pixels and text height pixels in the dot matrix pixel data are the pixels corresponding to the screen height; for example, if the screen height of the LED screen is 32 pixels, then a single character will generate a pixel matrix of 32 rows × 32 columns; the text pixel set includes at least one display area; the display quantity is the number of display areas that can be placed on the LED screen at one time; the starting coordinates are the starting coordinates corresponding to the display area, which are used for subsequent scrolling.

[0027] Specifically, the text content is split into at least one character and its corresponding text order, which indicates the subsequent movement order of the characters. Based on the screen height of the target display screen, such as 32 pixels, the width and height of the text are determined. The text is then transformed into a pixel matrix to obtain the corresponding dot matrix pixel area, which serves as the display area. This display area can contain 32 rows of pixels. The system uses 32 columns of pixels. The display areas corresponding to each character are sorted according to text order to obtain a text pixel set. The number of pixels to be displayed is determined based on the ratio between the screen width in the target display screen data and the width of the display area. For example, if the screen width is 192 and the display area width is 32, then the corresponding number of pixels that can be displayed is 6. The starting coordinates of the display area are determined based on the text order, the number of pixels to be displayed, and the target screen data. For example, if the bottom left corner of the target screen is the origin, the top left corner of the display area is used as the starting coordinate (0,32), with a width of 32 and a height of 32. Therefore, the display area contains pixels ranging from (0,32) to (32,0) from the top left to the bottom right corner. The starting coordinates of the display area are determined by the screen width of the target screen data. For example, if a line of dynamic text contains 7 pixels, then the text pixel set includes... ;but For a display area, there are 32 lines. A 32-column pixel matrix, where i is the text's sequence number; then Let's define the display area corresponding to the text with serial number 1. Since the text moves to the left, the starting position on the LED screen is the top left corner, which is (0, 32), and the ending position is the right side. Its corresponding starting coordinates are (0, 32); then The corresponding starting coordinates are (33, 32), and so on. The starting vertical axis coordinate for each subsequent display is equal to the starting vertical axis coordinate of the previous display plus 32. Its corresponding coordinates are (151, 32). Since its corresponding vertical axis coordinates already satisfy the width of its LED screen, its corresponding starting vertical axis coordinates are the starting vertical axis coordinates of the previous display + 32 - 192. Its corresponding coordinates are (-1, 32), so subsequent scrolling can be performed based on the subsequent movement offset.

[0028] It is understandable that by pixelating and calculating the display area of ​​a single character, the starting coordinates of the character are pre-set so that it can be moved according to the offset later.

[0029] In an optional embodiment of the present invention, the display area of ​​each character, including the width and height of the pixel matrix and the starting coordinates of the display area, can be associated and mapped with the serial number identifier corresponding to each character, and stored in the character display queue, so as to facilitate real-time updates of the coordinates in the character display queue during subsequent movements.

[0030] Understandably, each movement only sends the coordinates of the corresponding text to the LED control board, effectively avoiding the need to transmit complete pixel data for each frame as in the traditional method. For high-resolution LED screens, only the corresponding movement coordinates are transmitted, effectively avoiding transmission delays and packet loss issues caused by high bandwidth requirements.

[0031] S130. Determine the integer pixel offset list corresponding to the display area based on the starting coordinates of the display area and the special effects data; the integer pixel offset list includes the integer pixel offset of the display area at each time point.

[0032] The integer pixel offset list is pre-built, and each display area corresponds to the integer pixel offset at each time point within the total movement time.

[0033] Specifically, based on the starting coordinates of the display area and the special effects data, its corresponding movement speed is determined. Then, based on the movement speed and the current time point, its corresponding offset is determined. By associating the offset corresponding to the time point with the time point, a list of integer pixel offsets of the display area throughout the entire movement time is obtained.

[0034] Understandably, associating time points with offsets and outputting only integer pixel offsets instead of full frame data significantly reduces transmission bandwidth requirements and directly binds the time dimension to the pixel dimension, avoiding subpixel data transmission.

[0035] S140. Determine the current offset coordinates of the display area based on the current time, movement direction, and integer pixel offset list.

[0036] The current offset coordinates are the coordinates of the display area corresponding to the current time.

[0037] Specifically, the integer pixel offset corresponding to the current time is determined from the integer pixel offset list based on the current time. Based on the movement direction, the integer pixel offset and the previous coordinates of the display area are used to determine the current coordinate position, which is then used as the current offset coordinate.

[0038] Optionally, the current offset coordinates of the display area are determined from a list of integer pixel offsets based on the current time and direction of movement, including: Determine the target offset from the list of integer pixel offsets based on the current time; If the movement direction is to the left, the current offset coordinate of the display area is determined based on the difference between the offset coordinate of the display area at the previous moment and the target offset. If the movement direction is to the right, the current offset coordinate of the display area is determined by the sum of the offset coordinate of the display area at the previous moment and the target offset. If the movement direction is upward, the current offset coordinate of the display area is determined based on the difference between the offset coordinate of the display area at the previous moment and the target offset. If the movement direction is downward, the current offset coordinate of the display area is determined based on the difference between the offset coordinate of the display area at the previous moment and the target offset.

[0039] The offset coordinates of the previous moment can be either the starting coordinates of the display area or the current offset coordinates corresponding to the previous moment.

[0040] Specifically, the target offset corresponding to the current time is determined from the integer pixel offset list based on the current time; based on a pre-defined movement direction, such as moving left, right, up, or down; moving left and right moves the horizontal axis coordinate of the display area; moving up and down moves the vertical axis coordinate of the display area; if the movement direction is left, the current offset coordinate of the display area is determined by the sum of the previous offset coordinate and the target offset; if the movement direction is right, the current offset coordinate of the display area is determined by the difference between the previous offset coordinate and the target offset; if the movement direction is up, the current offset coordinate of the display area is determined by the sum of the previous offset coordinate and the target offset. If the movement direction is downward, the current offset coordinate of the display area is determined by the difference between the previous offset coordinate and the target offset. For example, if the display area moves to the right, its target offset is determined to be 1 pixel from the integer pixel offset list based on the current time, and its previous offset coordinate is (0, 32). Then the current offset coordinate is the difference between the vertical axis and the target offset in the previous offset coordinate, which is (-1, 32). If the display area moves to the right, its target offset is determined to be 0 pixels from the integer pixel offset list based on the current time, and its previous offset coordinate is (0, 32). Then the current offset coordinate is the difference between the vertical axis and the target offset in the previous offset coordinate, which is (0, 32).

[0041] Understandably, the integer pixel offset list stores integer pixel offsets. If the current time point is not found in the integer pixel offset list, the current offset coordinates are not calculated. The calculation is performed only when the offset is found at the next time point, thus avoiding subpixel transmission at the source.

[0042] Understandably, determining the moving pixel point at the current time point using an integer pixel offset list effectively avoids the sub-pixel transmission used in some traditional technologies, which requires the display to interpolate the sub-pixel data, increasing the computational burden on the display and potentially causing display delays and stuttering. Furthermore, traditional technologies require real-time calculation of pixel data for each frame, using an integer pixel offset list to calculate the current offset coordinates, avoiding complex calculation logic on the control end, high hardware performance requirements, and increased system costs.

[0043] S150. Determine the current frame data based on the current offset coordinates corresponding to each display area, and drive the LED module to display the current frame based on the current frame data.

[0044] The current frame data includes the pixel matrix of each display area and the current coordinates.

[0045] Specifically, based on the current offset coordinates of the display area and the corresponding pixel data of the display area, such as a 32x32 pixel matrix display area with current offset coordinates of (2,32), the corresponding pixel data, i.e., the range of the text pixel matrix displayed on the LED screen, is (2,32) to (34,0). The current offset coordinates and text pixel matrix range of each display area are determined sequentially as the current frame data, and the LED module is driven to display the current frame based on the current frame data. Pixels with negative coordinates, i.e., outside the screen, are removed, and only the pixels on the LED screen are retained for the current frame display.

[0046] Optional, also includes: Determine the boundary coordinates based on the direction of movement, target screen data, and display area; If the current offset coordinate is greater than or equal to the boundary coordinate, then stop displaying the current offset coordinate; If the current offset coordinate is less than the boundary coordinate, then the current offset coordinate is used as the current frame data, and the LED module is driven to display the current frame based on the current frame data.

[0047] Among them, the boundary coordinates are the coordinates of the pixel range of the LED screen data extending one display area based on the direction of movement.

[0048] Specifically, during text scrolling, the boundary coordinates are determined based on the direction of movement, specifying whether the change occurs on the horizontal or vertical axis. Further, the boundary is determined by the screen width and pixel range of the target screen data and the display area. If the movement is left-right, the boundary coordinates are the change in the screen width and pixel range of the target display screen along the horizontal axis. For example, if the display area has 32 rows and 32 columns of pixels, and the LED screen is 192 pixels wide and 32 pixels high, the corresponding boundary coordinates are (-32, 32) and (224, 32). If the movement is up-down, the boundary coordinates are the change in the screen height and pixel range of the target screen data along the horizontal axis. For example, if the display area has 32 rows and 32 columns of pixels, and the LED screen is 32 pixels wide and 192 pixels high, the corresponding boundary coordinates are (0, 224). (0, -32); During text scrolling, the current offset coordinate and boundary coordinate are judged in real time; if the current offset coordinate is greater than or equal to the boundary coordinate, for example, when the boundary coordinates are (-32, 32) and (224, 32), the current offset coordinate is (-32, 32), which means that the text corresponding to the display area is completely outside the screen, and the display of the current offset coordinate is stopped. If the current offset coordinate is less than the boundary coordinate, for example, when the boundary coordinates are (-32, 32) and (224, 32), the current offset coordinate is (-1, 32), which means that only one column of pixels in the pixel matrix corresponding to the display area has left the screen, and the display can continue. The current offset coordinate is used as the current frame data, and the LED module is driven to display the current frame based on the current frame data.

[0049] Understandably, to ensure display efficiency, boundary constraints are set to automatically confine the display area outside the screen, enabling the dynamic text to scroll infinitely.

[0050] This invention addresses the issue of text movement requests received via an interactive interface. The process involves: determining at least one display area based on the text content and target display screen data; determining an integer pixel offset list corresponding to the display area based on its starting coordinates and effect data; determining the current offset coordinates of the display area from the integer pixel offset list based on the current time and movement direction as the current frame data; and driving the LED module to display the current frame based on this current frame data. This technical solution ensures that the frame data contains integer pixel offsets, achieving efficient, stable, and smooth text movement on the LED screen, thus resolving the jitter problem inherent in existing text movement methods.

[0051] Figure 2This is a flowchart of an LED text special effects control method according to an embodiment of the present invention. Based on the above embodiments, this embodiment supplements the method for constructing the integer pixel offset list. It should be noted that for parts not described in detail in this embodiment, please refer to the relevant descriptions in other embodiments. For example... Figure 2 As shown, the method includes: S210, responding to the interactive interface to obtain a text movement request; the text movement request includes text content and corresponding effect data; the effect data includes frame rate, movement parameters, movement direction and target coordinates.

[0052] S220. Determine at least one display area based on the text content and the target display screen data.

[0053] S230. Calculate the movement parameters based on the frame number movement rule to obtain the number of frames the pixel moves.

[0054] The pixel movement frame count is the number of frames required to move one complete pixel.

[0055] Specifically, the pixel movement frame rate is obtained by performing an exponential operation with the difference between the frame number parameter and the movement parameter as the base and 2 as the exponent. For example, if the frame number parameter is 5 and the movement parameter is s, the difference between the frame number parameter and the movement parameter is 5-s. If the movement parameter is 4, the pixel movement frame rate is 2, that is, 1 pixel moves every 2 frames.

[0056] S240. Based on the direction of movement, determine the movement distance according to the target coordinates and the starting coordinates of the display area.

[0057] The movement distance is used to stop the movement of special effects data.

[0058] Specifically, depending on the direction of movement, if the movement is left or right, the movement distance is determined by the horizontal axis corresponding to the target coordinates and the starting coordinates of the display area; if the movement is up or down, the movement distance is determined by the vertical axis corresponding to the target coordinates and the starting coordinates of the display area.

[0059] S250. The total movement time, frame rate, number of pixel movement frames, and movement speed are rounded down using a rounding function, and combined with the movement distance to construct an integer pixel offset list.

[0060] Specifically, the product of the current time and the frame rate in the total movement time is calculated, the number of frames already run is determined by rounding down using the rounding function, and the current offset pixel is obtained by rounding down the ratio between the number of frames already run and the number of frames moved by the pixel, based on the movement distance.

[0061] Optionally, the total movement time, frame rate, number of frames moved per pixel, and movement speed are rounded down using a rounding function, and combined with the movement distance to construct a list of integer pixel offsets, including: The total travel time is broken down to obtain at least one point in time; The time interval is determined based on the time point and the initial time. The product of the time interval and the movement speed is rounded down using a rounding function to obtain the current offset frame number corresponding to the time point. The ratio between the current offset frame number and the pixel movement frame number is rounded down using a rounding function, and the minimum value between the ratio and the movement distance is selected as the current offset. Associate the time point with the current offset to construct a list of integer pixel offsets.

[0062] The time points are the current times corresponding to the total time.

[0063] Specifically, the total time is divided to obtain at least one time point; the time interval is determined based on the time point and the initial time; the time interval and the movement speed are rounded down using a rounding function to obtain the current offset frame number corresponding to the time point; the ratio between the current offset frame number and the pixel movement frame number is rounded down using a rounding function, and the minimum value is selected as the current offset from the movement distance; the time point is associated with the current offset to construct an integer pixel offset list, such as [(0,0),(2,1),(4,2),...,(60,30)], which means that when t=0, the previous offset is 0; when t=2, the current offset is 1, and so on.

[0064] S260. Determine the current offset coordinates of the display area based on the current time, movement direction, and integer pixel offset list.

[0065] S270. Determine the current frame data based on the current offset coordinates corresponding to each display area, and drive the LED module to display the current frame based on the current frame data.

[0066] The embodiments of the present invention achieve a smooth "pixel-by-pixel" movement effect through frame rate control, and the display position is updated only when the whole pixel movement is completed. At the same time, it avoids the phenomenon of different values ​​being calculated within 1 pixel when continuously moving text effects, which would cause the display to jitter with different values ​​within 1 pixel.

[0067] Figure 3This invention provides a schematic diagram of an LED text effect control device, applicable to situations where text is dynamically rendered on an LED screen, particularly suitable for LED displays. The LED text effect control device can be implemented in hardware and / or software and can be configured in a server. Figure 3 As shown, the LED text effect control device 300 includes an acquisition module 310, a display area determination module 320, an integer pixel offset list determination module 330, a current offset coordinate determination module 340, and a display module 350. The acquisition module 310 is used to acquire a text movement request in response to the interactive interface; the text movement request includes text content and corresponding special effects data; the special effects data includes movement direction, frame rate, movement parameters, total movement time, and target coordinates; Display area determination module 320 is used to determine at least one display area based on text content and target display screen data; The integer pixel offset list determination module 330 is used to determine the integer pixel offset list corresponding to the display area based on the starting coordinates of the display area and the special effects data; the integer pixel offset list includes the integer pixel offset of the display area at each time point. The current offset coordinate determination module 340 is used to determine the current offset coordinates of the display area based on the current time, the direction of movement, and an integer pixel offset list. The display module 350 is used to determine the current frame data based on the current offset coordinates corresponding to each display area, and drive the LED module to display the current frame based on the current frame data.

[0068] This invention addresses the issue of text movement requests received via an interactive interface. The process involves: determining at least one display area based on the text content and target display screen data; determining an integer pixel offset list corresponding to the display area based on its starting coordinates and effect data; determining the current offset coordinates of the display area from the integer pixel offset list based on the current time and movement direction as the current frame data; and driving the LED module to display the current frame based on this current frame data. This technical solution ensures that the frame data contains integer pixel offsets, achieving efficient, stable, and smooth text movement on the LED screen, thus resolving the jitter problem inherent in existing text movement methods.

[0069] Optionally, the integer pixel offset list determination module 330 is specifically used to calculate the movement parameters based on the frame number movement rule to obtain the pixel movement frame number; Based on the direction of movement, the movement distance is determined according to the target coordinates and the starting coordinates of the display area; The total movement time, frame rate, number of frames moved per pixel, and movement speed are rounded down using a rounding function and combined with the movement distance to construct a list of integer pixel offsets.

[0070] Optionally, the integer pixel offset list determination module 330 is specifically used to split the total movement time to obtain at least one time point; The time interval is determined based on the time point and the initial time. The product of the time interval and the movement speed is rounded down using a rounding function to obtain the current offset frame number corresponding to the time point. The ratio between the current offset frame number and the pixel movement frame number is rounded down using a rounding function, and the minimum value between the ratio and the movement distance is selected as the current offset. Associate the time point with the current offset to construct a list of integer pixel offsets.
