[0002] Monochrome LED displays are favored by developers in fields that do not require high-precision display, such as simple time display, due to their low price. However, monochrome LED displays only have two states: on and off, which makes the display relatively simple and unable to be flexibly displayed according to user requirements.

[0008] The target display pattern is obtained by scanning the pattern to be displayed based on each pixel density mask in the pixel density mask set;

[0009] The target display pattern is used to control the LED display screen to perform a gradient display.

[0010] In one embodiment, the step of determining the set of pixel density masks representing different lighting states of the LED display screen based on the pixel values ​​includes:

[0011] The number of pixels lit is determined by the pixel values;

[0012] The display screen lighting states are divided according to the number of lit pixels, resulting in multiple lighting states of the display screen;

[0013] A set of pixel density masks is constructed using the various lighting states of the display screen.

[0014] In one embodiment, the step of scanning the pattern to be displayed based on each pixel density mask in the pixel density mask set to obtain the target display pattern includes:

[0015] The aggregated pixel coordinates are obtained based on each pixel density mask in the pixel density mask set.

[0016] The pixel density mask is used to scan each point in the pattern to be displayed, and the pixels in the pattern to be displayed that are at the same position as the summed pixel coordinates are compared.

[0017] When the pixel value of the corresponding pixel on the pattern to be displayed is a first value, the pixel is used as the display pixel, and the first value indicates that the pixel is displayed in a first state;

[0018] When the pixel value of the corresponding pixel on the pattern to be displayed is the second value, the scanning of the pixel is skipped until the scanning is completed, and a set of display pixels is obtained. The second value indicates that the pixel is displayed in the second state, which is different from the first state and the second state.

[0019] The target display pattern is obtained through the set of display pixels.

[0040] The display module is used to control the LED display screen to perform a gradient display based on the target display pattern.

[0041] In addition, to achieve the above objectives, this application also proposes an LED display screen display control device, the device comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, the computer program being configured to implement the steps of the LED display screen display control method as described above.

[0042] In addition, to achieve the above objectives, this application also proposes a storage medium, which is a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, it implements the steps of the LED display screen display control method described above.

[0043] In addition, to achieve the above objectives, this application also provides a computer program product, which includes a computer program that, when executed by a processor, implements the steps of the LED display screen display control method described above.

[0045] By determining the pixel density mask set for different lighting states of the display screen based on the pixel values, the target display pattern in different display states can be obtained by scanning the pattern to be displayed using different pixel density mask sets. This allows for a gradual display of the target display pattern on the LED display screen. By adding a fade-in / fade-out effect to the LED display screen, costs are reduced, the display effect of the LED display screen is improved, the flexibility of the LED display screen is increased, and the user experience is enhanced.

[0061] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0062] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0063] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0064] The main solution of this application embodiment is: to obtain the pixel value of the LED display screen; to determine a set of pixel density masks representing different lighting states of the LED display screen based on the pixel value; to scan the pattern to be displayed based on each pixel density mask in the set of pixel density masks to obtain the target display pattern; and to control the LED display screen to perform gradient display based on the target display pattern.

[0065] In this embodiment, for ease of description, the following description will focus on identifying the LED display screen control device as the execution subject.

[0066] Because existing monochrome LED displays only have two states, on and off, they cannot flexibly adjust the display interface according to user needs. If a gradient display is required, a multi-color LED display is needed, but multi-color displays are more expensive, and using only monochrome LED displays cannot flexibly adjust the display according to user needs.

[0067] This application provides a solution that allows a monochrome LED display to add a fade-in / fade-out effect to the display, reducing display costs while improving the user experience.

[0068] As can be seen from the above embodiments, this application first obtains the pixel values ​​of the LED display screen; determines a set of pixel density masks representing different lighting states of the LED display screen based on the pixel values; scans the pattern to be displayed based on each pixel density mask in the set of pixel density masks to obtain the target display pattern; and controls the LED display screen to perform gradient display through the target display pattern. This overcomes the technical problems of monochrome LED display screens being monotonous and inflexible, thereby achieving the effect of adding fading and revealing on the basis of display, which reduces costs, improves the display effect of the LED display screen, and enhances the user experience.

[0069] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or LED display screen control device capable of performing the above functions. The following description uses an LED display screen control device as an example to illustrate this embodiment and the subsequent embodiments.

[0070] Based on this, this application provides an LED display screen display control method. Referring to FIG1, FIG1 is a flowchart of the first embodiment of the LED display screen display control method of this application.

[0071] In this embodiment, the LED display screen display control method includes steps S10 to S40:

[0072] Step S10: Obtain the pixel values ​​of the LED display screen.

[0073] It should be noted that the LED display screen refers to a monochrome LED display screen, such as a fixed monochrome LED display screen used to display static or scrolling text information, graphics, or simple animations; flexible monochrome LED display screens, etc.

[0074] The pixel value of a monochrome LED display screen can be the value of each pixel on the monochrome LED display screen. The pixel value can be recorded by constructing a display array. The value of being off is defined as 0, and the value of being on is defined as 1. The pixels in the monochrome LED display screen can be divided first, and the pixel value of the divided pixels can be obtained.

[0075] Additionally, it should be noted that in order to achieve the effect of fading in and out, the pixels in the LED display screen can be re-divided.

[0076] In one feasible implementation, step S10 may include steps A11 to A14:

[0077] Step A11: Obtain the raw pixel count of the LED display screen;

[0078] It should be noted that the original pixels are the undivided pixels on the monochrome LED display screen.

[0079] As shown in Figure 2, the monochrome LED display screen is composed of multiple pixels, i.e., original pixels, and each pixel only has the function of turning on and off.

[0080] To achieve a fade-in / fade-out display effect, this embodiment re-divides the original pixels.

[0081] Step A12: Divide the original pixels to obtain multiple groups of divided pixels;

[0082] It should be noted that when dividing the original pixels, you can first set the division rules, such as the number of new pixels in each group. For example, you can set the number of new pixels in each group to 4, 6, 8, etc., which can be set according to specific needs. The more new pixels in each group, the more detailed the pixel density mask will be.

[0083] For example, if the division rule is that each group of new pixels contains 4 pixels, then the original pixels are divided into groups of 4, and each group is a set of divided pixels, thus obtaining multiple sets of divided pixels. As shown in Figure 3, Figure 3 is a schematic diagram of dividing the original pixels to obtain multiple sets of divided pixels. Every four adjacent pixels (a grid) form a group of pixels, thus obtaining multiple sets of divided pixels.

[0084] Step A13: Locate the multiple groups of divided pixels based on a preset drawing point function to obtain the position of the divided pixels;

[0085] Understandably, the preset drawing point function can be constructed using the C language. The function Point(x,y) is used to locate each pixel in the pixel division. It can locate each group of pixel divisions separately, thereby quickly determining the position of the pixel divisions.

[0086] Furthermore, the step of locating the multiple groups of segmented pixels based on a preset drawing point function to obtain the position of the segmented pixels includes: locating each group of segmented pixels in the multiple groups of segmented pixels based on the preset drawing point function to obtain the coordinates of the segmented pixels; and obtaining the position of the segmented pixels through the coordinates of the segmented pixels.

[0087] It should be noted that each group of pixels can be divided into coordinates to obtain the coordinates of each pixel within the group. The position of each pixel can be quickly obtained by using these coordinates. As shown in Figure 4, this is a schematic diagram of the process of locating the pixels and obtaining their coordinates. For example, if there are four pixels in the group, by dividing each pixel into coordinates, we can divide it into the top left corner (0,0), the top right corner (1,0), the bottom left corner (0,1), and the bottom right corner (1,1), and so on, thus obtaining the position of all pixels in the monochrome display screen.

[0088] Step A14: Determine the pixel value of the LED display screen by dividing the pixel positions.

[0089] It should be noted that the pixel value of each divided pixel in the LED display screen can be determined by dividing the pixel position.

[0090] Specifically, rules for recording pixel values ​​can be pre-set to quickly determine the values ​​of each divided pixel. The steps for determining the pixel values ​​of the LED display screen based on the positions of these divided pixel points include:

[0091] Obtain a preset value recording rule; traverse the divided pixel positions to obtain the number of different pixels lit in each group of divided pixels; record the number of pixels lit by the preset value recording rule to obtain the pixel value of the LED display screen.

[0092] It should be noted that the preset value recording rule is a rule for defining the recording of pixel values. A display array Show[n] can be constructed to record the value of the current pixel. The value of being off is defined as 0, and the value of being on is defined as 1. By traversing the positions of the divided pixels, the number of different pixels lit in each group of pixels can be obtained. For example, if there are 4 pixels in a group, the number of pixels lit can be one of five types: all off (0 pixels lit); only one pixel lit (1 pixel lit); two pixels lit (2 pixels lit); three pixels lit (3 pixels lit); and all pixels lit (4 pixels lit). By obtaining the pixel values ​​of each divided pixel through the different number of pixels lit, the pixel values ​​of all pixels in the LED display screen can be obtained.

[0093] Step S20: Determine the set of pixel density masks that represent different lighting states of the LED display screen based on the pixel values.

[0094] It should be noted that the number of pixels lit can be determined by the pixel value. Based on the different numbers of pixels lit, a set of pixel density masks representing different lighting states of the LED display can be obtained.

[0095] The pixel density mask set includes masks with different pixel densities. Pixel density masks are grayscale masks. For example, the pixel density mask set includes a mask with a pixel density of 0%, meaning that all pixels on the display screen are turned off and the pixel values ​​are all 0. It can also include masks with a pixel density of 50%, masks with a pixel density of 100%, etc. The number of pixels to be divided can be determined according to the pixel division rules to obtain the number of recovery masks. For example, if the number of pixels to be divided is n, then there are n-1 grayscale masks.

[0096] Step S30: Scan the pattern to be displayed based on each pixel density mask in the pixel density mask set to obtain the target display pattern.

[0097] In practice, the pixel density mask set contains masks with different pixel densities. By scanning the pattern to be displayed using different pixel density masks, a new scanned pattern can be obtained.

[0098] The pattern to be displayed is the pattern that the user wants to display on the monochrome LED display screen. By superimposing the pattern to be displayed with a mask of corresponding pixel density, the corresponding display pattern can be obtained, as shown in Figure 5. Figure 5 is a schematic diagram of superimposing the pattern to be displayed on the monochrome LED display screen and a 50% grayscale mask. For example, the pattern to be displayed on the current monochrome LED display screen is to display a capital letter E. By superimposing it with a grayscale mask with a pixel density of 50%, it can be found that some pixels of the display pattern and the grayscale mask overlap. By superimposing and scanning grayscale masks with different pixel densities with the pattern to be displayed, multiple target display patterns can be obtained.

[0099] Step S40: Control the LED display screen to perform a gradient display through the target display pattern.

[0100] In practice, the LED display screen can be controlled to display a gradient effect by controlling the target display pattern. Gradient display refers to controlling the monochrome LED display screen to gradually fade in and out.

[0101] Furthermore, since different displays can be provided according to the display needs of different users, step S40 includes:

[0102] Obtain a display instruction; determine the density display timing according to the display instruction; control the display patterns of different display densities in the target display pattern to be displayed gradually on the LED display screen in sequence through the density display timing.

[0103] It is understood that the display instructions may include display density of the target display pattern from high to low or display density of the target display pattern from low to high, which can be selected according to specific needs.

[0104] In practical implementation, the density display timing can be determined by analyzing the display instructions. For example, if the density display timing is from low to high, the display pattern with low display density in the target display pattern can be displayed on the LED display screen first, and then the display pattern with high display density in the target display pattern can be displayed on the LED display screen later.

[0105] To achieve a fade-in / fade-out effect, a grayscale function Gray(x) can be created. This function Gray(x) sequentially calls values ​​from the video memory array Show[n] in different grayscale masks, thus calling target display patterns with different pixel densities. For example, to achieve a fade-in / fade-out effect, the target display pattern can be displayed sequentially from 0% to 25% to 50% to 75% to 100% using the following pixel density mask. To achieve a fade-in / fade-out effect, the target display pattern can be displayed sequentially from 100% to 75% to 50% to 25% to 0%.

[0106] This embodiment obtains the pixel values ​​of the LED display screen; determines a set of pixel density masks representing different lighting states of the LED display screen based on the pixel values; scans the pattern to be displayed based on each pixel density mask in the set to obtain the target display pattern; and controls the LED display screen to perform gradient display through the target display pattern. By scanning the pattern to be displayed using the set of pixel density masks, a fade-in / fade-out effect is added to the display, which reduces costs, improves the display effect of the LED display screen, and enhances the user experience.

[0107] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in the first embodiment described above can be referred to the above description and will not be repeated hereafter. Based on this, please refer to Figure 6, step S20 specifically includes:

[0108] Step S201: Determine the number of pixels lit up based on the pixel values.

[0109] It should be noted that the number of pixels lit can be determined by the pixel value. For example, if the pixel value is 0, then the number of pixels lit is 0. If the pixel values ​​in each group of pixels are 1, 0, 0, 0, then the number of pixels lit is 1.

[0110] Similarly, the number of pixels to be lit can be determined based on the pixel values ​​within each group of pixels.

[0111] Step S202: Divide the display screen lighting state according to the number of lit pixels to obtain multiple display screen lighting states.

[0112] In practical implementation, the display screen lighting state can be divided by the number of pixels lit, thus obtaining multiple lighting states of the display screen, as shown in Figure 7. Figure 7 is a schematic diagram of dividing different lighting states of pixels. By dividing the number of four pixels lit in a pixel, it can be divided into five states, including all off, only one pixel lit (0,0), two pixels lit (0,0) and (1,1), three pixels lit (0,0), (1,0) and (1,1), and all pixels lit (0,0), (1,0), (1,1) and (0,1).

[0113] Step S203: Construct a set of pixel density masks using the various illumination states of the display screen.

[0114] In practice, if the screen is filled with the above-mentioned multiple lighting states, visual effects with different pixel densities can be obtained, i.e., grayscale masks. By summarizing the grayscale masks with different pixel densities, a set of pixel density masks can be obtained.

[0115] As an example, if each group of pixel illumination states includes five states: all off, only one pixel lit, two pixels lit, three pixels lit, and all pixels lit, then the resulting pixel densities are 0%, 25%, 50%, 75%, and 100%, as shown in Figure 8. Figure 8 is a schematic diagram of the display effect of different pixel densities. From left to right, the pixel density is 0% for all off, 25% for only one pixel lit, 50% for two pixels lit, 75% for three pixels lit, and 100% for all pixels lit.

[0116] This embodiment determines the number of lit pixels based on the pixel values; it then divides the display screen's illumination state according to the number of lit pixels, resulting in multiple illumination states; and it constructs a set of pixel density masks based on these multiple illumination states. This allows for the rapid construction of grayscale masks with different pixel densities based on the pixel values, thereby enabling different display effects to be achieved without altering the display screen's hardware structure and reducing costs.

[0117] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in the first embodiment described above can be referred to the above description and will not be repeated hereafter. Based on this, please refer to Figure 9, step S30 specifically includes:

[0118] Step S301: Obtain the aggregated pixel coordinates based on each pixel density mask in the pixel density mask set.

[0119] It should be noted that different pixel density masks can be obtained from the set of pixel density masks, and the coordinates of each pixel point in each pixel density mask can be obtained by statistical analysis. The coordinates of all pixel points can be summarized to obtain the summarized pixel point coordinates.

[0120] Step S302: Scan each point in the pattern to be displayed using the pixel density mask, and compare the pixels in the pattern to be displayed with the pixels at the same position in the aggregated pixel coordinates.

[0121] In practice, different pixel density masks are used to scan each point in the pattern to be displayed, and the pixels in the pattern to be displayed that are at the same position as the sum of pixel coordinates are compared.

[0122] For example, the pixel coordinates on a 50% grayscale mask are scanned one by one and compared with the pixels at the same position on the pattern to be displayed.

[0123] Step S303: When the pixel value of the corresponding pixel on the pattern to be displayed is a first value, the pixel is used as a display pixel, and the first value indicates that the pixel is displayed in a first state.

[0124] During the comparison process, if the pixel value of the corresponding pixel on the pattern to be displayed is the first value, then the pixel can be used as the display pixel. The first value is 1, and the corresponding pixel state should be lit. The display pixel is the pixel that will be used as the point of light in the display pattern when it is displayed later.

[0125] In practice, the first value indicates that the pixel is displayed in the first state, which is the lit state.

[0126] Step S304: When the pixel value of the corresponding pixel on the pattern to be displayed is the second value, skip scanning the pixel until the scanning is completed to obtain a set of display pixels. The second value indicates that the pixel is displayed in a second state, which is different from the first state.

[0127] During the comparison, if the pixel value of the corresponding pixel on the pattern to be displayed is the second value, then the scanning of this pixel is skipped, the second number is 0, and the corresponding pixel state should be off. The second state is the off state.

[0128] By comparing each pixel on the pattern to be displayed with the pixel density mask, all pixels are scanned, and the pixels are filtered to obtain the set of display pixels.

[0129] Step S305: Obtain the target display pattern through the set of display pixels.

[0130] In practice, a new display pattern, i.e., the target display pattern, can be constructed by displaying a set of pixels.

[0131] By overlaying grayscale masks with different pixel densities onto the pattern to be displayed, display patterns with different pixel densities can be constructed, ultimately resulting in target display patterns with multiple pixel densities.

[0132] For example, the pixel coordinates on the 50% grayscale mask are scanned one by one and compared with the pattern "E" to be displayed. If the value of the corresponding pixel on the display pattern is 0 (off state), the point is skipped and the scan continues; if the value of the corresponding pixel is 1 (on state), then this point is used as the display pixel. A point can also be drawn at the same coordinate position using the drawing function Point(x,y) in the video memory array Show[n]. After all the points corresponding to the pattern to be displayed on the screen have been scanned, the coordinates of all the intersecting pixels on the grayscale mask and the pattern to be displayed are stored in the video memory array Show[n] as the value 1. Thus, a target display pattern with a pixel density of 50% is obtained. Similarly, by overlaying and scanning with grayscale masks of different pixel densities, three other patterns with pixel densities of 25%, 75%, and 100% can be obtained, as shown in Figure 10. Figure 10 is a schematic diagram of the target display pattern effect obtained by overlaying grayscale masks of different pixel densities. From left to right, they are the target display pattern with a pixel density of 25%, a target display pattern with a pixel density of 50%, a target display pattern with a pixel density of 75%, and a target display pattern with a pixel density of 100%.

[0133] This embodiment obtains the aggregated pixel coordinates based on each pixel density mask in the pixel density mask set; it scans each point in the pattern to be displayed using the pixel density mask, comparing pixels in the pattern to be displayed with those at the same positions in the aggregated pixel coordinates; when the pixel value of the corresponding pixel in the pattern to be displayed is a first value, the pixel is used as a display pixel, where the first value indicates that the pixel is displayed in a first state; when the pixel value of the corresponding pixel in the pattern to be displayed is a second value, the scanning of the pixel is skipped until the scanning is complete, resulting in a set of display pixels, where the second value indicates that the pixel is displayed in a second state, which is different from the first state; by obtaining the target display pattern through the set of display pixels, grayscale masks with different pixel densities can be quickly scanned with the pattern to be displayed, thereby obtaining target display patterns with different display densities and improving the display effect of the pattern.

[0134] For example, to help understand the implementation flow of the LED display control method obtained by combining this embodiment with the above embodiment one, please refer to Figure 11. Figure 11 provides a simplified flowchart of an LED display control method. Specifically: First, a preset drawing point function Point(x,y) is constructed. The preset drawing point function is used to locate the pattern pixels in the LED display screen. A display memory array Show[n] is constructed to record the pixel values. The lit state is recorded as 1, and the off state is recorded as 0. The display screen is divided into five different lit states by different numbers of lit pixels, resulting in five pixel density masks. The display patterns are scanned sequentially through the density masks to obtain five new patterns with different pixel densities. The user's command is to light up or turn off. If it is lit up, the target display pattern is displayed sequentially according to the pixel density mask from 0% → 25% → 50% → 75% → 100%. If it is off, the target display pattern is displayed sequentially according to the pixel density mask from 100% → 75% → 50% → 25% → 0%.

[0135] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the LED display control method of this application. Any simple modifications based on this technical concept are within the protection scope of this application.

[0136] This application also provides an LED display screen control device, as shown in Figure 12, the LED display screen control device comprising:

[0137] The acquisition module 10 is used to acquire the pixel values ​​of the LED display screen.

[0138] The determination module 20 is used to determine the set of pixel density masks that characterize different lighting states of the LED display screen based on the pixel values.
