[0050] Please refer to Figure 1 and Figure 2 , the present embodiment provides a text display method of a multi-screen, the multi-screen 100 is formed by splicing two or more display screens 101, the method comprises the following steps:

[0051] S101, set the resolution of the text in the text along the first direction to be equal to 1 / n of the resolution of the display screen along the first direction, or set the width of the text along the first direction to be equal to 1 / n of the width of the display screen along the first direction, the n is an integer greater than 2;

[0052] S102, set the display position of the text in the text on the multi-screen, so that any one of the text in the text is displayed on one of the display screens.

[0053] As Figure 2 shown, in the present embodiment, the multi-screen 100 is spliced along the length and / or width direction by a plurality of display screens 101 (i.e. sub-display screens), thereby forming a multi-screen with larger size. When displaying, the display control device of the multi-screen 100 cuts the display content according to the position and size of each display screen 101, and then sends it to the corresponding display screen 101 for display. In the present embodiment, the display screen 101 can be an LCD display, an OLED display, a Micro LED display, etc. Among them, each display screen 101 is preferably several display screens of the same model or the same size and resolution.

[0054] In step S101, the first direction can be the width direction of the multi-screen, as Figure 2As shown, the text 103 in the text is arranged along the width direction of the multi-screen 100, and the first direction is the width direction of the multi-screen. In some embodiments, the text may also be arranged along the height direction of the multi-screen (i.e., the text is vertically arranged), in which case the first direction may also be the height direction of the multi-screen. In step S101, the text in the text is not limited to Chinese characters; it may also be English, numbers, Japanese, or other languages ​​or characters. In addition to displaying the above text, the multi-screen can also display images or videos such as music videos, movies, games, and advertisements, where text can be displayed on the surface of these images or videos. The text may be the lyrics of a song, or subtitles corresponding to movies and games. This multi-screen can be applied to the display screens of multimedia on-demand devices such as karaoke machines in digital entertainment venues such as KTVs and bars.

[0055] In step S101, the resolution of the display screen in the first direction should be divisible by the resolution of a single character 103 in the same direction. That is, the resolution of a single character in the text along the first direction is equal to 1 / n of the resolution of the display screen along the first direction, where n is an integer greater than 2. For example, in one embodiment, when the horizontal resolution of each display screen is 1920, the horizontal resolution of a single character can be 1920 / 5 = 384, 1920 / 6 = 320, 1920 / 8 = 240, etc.

[0056] In another embodiment, the width of the text along the first direction can be set to be equal to 1 / n of the width of the display screen along the first direction. For example, if the width of the display screen along the first direction is 14 inches, the width of a single character in the text along the first direction can be 14 / 7 = 2 inches, 14 / 10 = 1.4 inches, etc.

[0057] In this embodiment, each character 103 has the same width or resolution in the first direction and is arranged at equal intervals. Therefore, in step S102, by adjusting the position of one character 103, the position of other characters in the same line of text can be adjusted, and each character will not fall on the splicing seam 1011 of the display screen.

[0058] In this embodiment, by setting the resolution or width of the font of the text in the displayed text along the first direction, the resolution or width of a single character is made to be exactly 1 / n of the resolution or width of the display along the first direction. Furthermore, the horizontal position of the text is set so that any character is displayed on only one display screen, avoiding text distortion when displayed across display screens and improving the text display effect of multi-screen displays.

[0059] like Figure 2 As shown, in some embodiments, the above-described multi-screen text display method further includes the step of:

[0060] At least one window 102 is created on the multi-screen display, and the text is displayed within the window 102.

[0061] The step of "setting the display position of the text in the text on the multi-screen display so that any one of the text characters is displayed on only one of the display screens" includes the following steps:

[0062] The position of the form on the multi-screen display is set, and the position of the text within the form is set, so that any one of the characters in the text is displayed on only one of the display screens.

[0063] In this embodiment, the window 102 is merely a window used for text adjustment and display, and the window is not necessarily visually visible on the multi-screen 100. In some embodiments, the window 102 may be transparent, without a border, background color, or texture, so that no display style is visible, and only the text displayed within the window is visible. In other embodiments, the window 102 may have any one or more display styles with a certain border, background color, and texture, so that in addition to the text displayed within the window, the border, background color, or texture of the window may also be visible.

[0064] like Figure 2 As shown, in one embodiment, the multi-screen 100 is provided with two windows 102: a first window and a second window. The first window and the second window are arranged along a second direction perpendicular to the first direction. That is, if the first direction is the width direction of the multi-screen, the first window and the second window are distributed one above the other along the height direction of the multi-screen, for example, arranged in two rows in height. If the first direction is the height direction of the multi-screen, the first window and the second window are distributed one to the left and one to the right along the width direction of the multi-screen.

[0065] A portion of the text is displayed in the first window, and the other portion of the text is displayed in the second window.

[0066] The starting horizontal coordinate of the first window is equal to the starting horizontal coordinate of the multi-screen in the first direction + the number of indented characters * the resolution of a single character in the first direction. The resolution of the first window along the first direction is equal to the resolution of the multi-screen in the first direction - the number of header indented characters * the resolution of a single character along the first direction. The starting horizontal coordinate of the text in the first window is the same as the starting horizontal coordinate of the first window.

[0067] The starting horizontal coordinate of the second window is equal to the starting horizontal coordinate of the multi-screen in the first direction; the resolution of the second window is equal to the resolution of the multi-screen in the first direction - the number of characters for the tail indentation * the resolution of a single character along the first direction; the tail position of the last character in the second window coincides with the tail position of the second window.

[0068] The starting vertical coordinate of the first window is equal to the starting vertical coordinate of the multi-screen display + the resolution of the multi-screen display along the second direction * a first preset value, where the first preset value is less than 1 and greater than 0.5.

[0069] The starting vertical coordinate of the second window is equal to the starting vertical coordinate of the first window plus the resolution of a single text along the second direction * (1 + second preset value), where the second preset value is greater than 0 and less than 0.5.

[0070] like Figure 2 As shown, in one embodiment, the upper left corner of the multi-screen display is first taken as the origin of the coordinate system, the horizontal axis extends to the right (which can be the first direction), and the vertical axis extends downwards (which can be the second direction). Setting the size and position of the window includes:

[0071] Set the coordinates of the top left corner of the first window:

[0072] The horizontal coordinate of the top left corner of the first window = the horizontal coordinate of the top left corner of the multi-screen display + the number of indented characters * the horizontal resolution of a single character; (the top left corner of the multi-screen display is the top left corner when the multi-screen display is treated as a whole).

[0073] The vertical coordinate of the top left corner of the first window = the vertical coordinate of the top left corner of the multi-screen + the vertical resolution of the multi-screen * 5 / 8 (i.e., the first preset value); (the first preset value "5 / 8" here is the position slightly below the vertical center of the screen. Other values ​​can also be set, but enough screen space must be reserved for the first line of text and the second line of text below it to display the text, otherwise the text may not be fully displayed).

[0074] The horizontal resolution of the first window = the horizontal resolution of the multi-screen layout - the number of indented characters * the horizontal resolution of a single character; (the first line of text has a header indent, and the second line of text has a footer indent. The unit of indentation is the number of characters. The size of these two indentations can be the same or different).

[0075] The vertical resolution of the first window = the vertical resolution of the lyrics = the vertical resolution of the font + the outline width (the lyrics have an outline set for better display); where the outline width is the number of pixels in a vertical direction (vertical).

[0076] Set the coordinates of the top left corner of the second window:

[0077] The horizontal coordinate of the upper left corner of the second window = the horizontal coordinate of the upper left corner of the multi-screen;

[0078] The vertical coordinate of the upper left corner of the second window = the vertical coordinate of the upper left corner of the first window + the vertical resolution of the first window + the vertical resolution of the font / 8; (1 / 8 is the second preset value, and the additional font height / 8 is the vertical spacing of two rows of windows.)

[0079] The horizontal resolution of the second window = the horizontal resolution of the multi-screen - the number of indented words * the horizontal resolution of a single character;

[0080] The vertical resolution of the second window = the vertical resolution of the lyrics = the vertical resolution of the font + the outline width (the lyrics have a set outline, so the display effect is better), wherein the outline width is the number of pixels in a vertical direction (vertical direction).

[0081] In an embodiment, in order to make the displayed text have a better display effect, the character includes a main body and an outline, and the text is displayed in the window by drawing, including the steps of:

[0082] According to the preset font size, the main body of the character is drawn in the window, and then the outline is drawn outside the main body according to the preset outline size.

[0083] The main body and the outline of the character can be set to different colors to achieve a better display effect.

[0084] In a preferred embodiment, 1 / n of the resolution of the display screen in the first direction or 1 / n of the width of the display screen in the first direction is an integer greater than 1. Since the resolution or width of the display screen in the first direction can be divided by n, the text in the text can be avoided when arranging on the multi-screen. Fine-tuning error occurs.

[0085] In a preferred embodiment, when drawing the first window or the second window according to the width of the display screen, the above method can be referred to, for example:

[0086] First, the upper left corner of the multi-screen is taken as the origin of the coordinate system, the horizontal axis extends to the right (which can be the first direction), and the vertical axis extends downward (which can be the second direction), wherein setting the size and position of the window includes:

[0087] Setting the upper left corner coordinate of the first window:

[0088] The horizontal coordinate of the upper left corner of the first window = the horizontal coordinate of the upper left corner of the multi-screen + the number of indented words * the horizontal width of a single character; (The upper left corner of the multi-screen is when the multi-screen is taken as a whole, and its upper left corner is)

[0089] The vertical coordinate of the upper left corner of the first window = the vertical coordinate of the upper left corner of the multi-screen + the vertical height of the multi-screen * 5 / 8 (i.e. the first preset value); (The first preset value "5 / 8" herein is a position slightly below the vertical middle of the screen, and other values can also be set, but sufficient screen space should be reserved for the first line of text and the second line of text below it to display the text, otherwise the text can not be fully displayed).

[0090] The horizontal width of the first window = the horizontal width of the multi-screen - the number of indented characters * the horizontal width of a single character; (The first line of text has a first indentation, and the second line of text has a second indentation, and the sizes of the two indentations can be the same or different.)

[0091] The vertical height of the first window = the vertical height of the lyrics = the vertical height of the font + the outline width;

[0092] The coordinates, width and height of the second window are also set similarly.

[0093] As shown in FIG. 1, in one embodiment, a multi-screen text display device 100 is provided for displaying text on a multi-screen. Figure 3 As shown in FIG. 2, in another embodiment, a multi-screen text display device 400 is provided for displaying text on a multi-screen. Figure 2 The multi-screen 100 is formed by splicing two or more display screens 101. The multi-screen text display device 400 includes a first setting module 10 and a second setting module 20.

[0094] The first setting module 10 is configured to set the width of a character in the text along a first direction to be equal to 1 / n of the resolution of the display screen along the first direction, where n is an integer greater than 2.

[0095] The second setting module 20 is configured to set the display position of the character in the text on the multi-screen, so that any one of the characters in the text is displayed on only one of the display screens.

[0096] In this embodiment, by setting the font width of the character in the displayed text along the first direction to be exactly 1 / n of the resolution of the display along the first direction, and further setting the horizontal position of the character so that any one of the characters is displayed on only one of the display screens, the deformation of the character due to display across the display screens is avoided, and the text display effect of the multi-screen is improved.

[0097] The multi-screen text display device 400 further includes a creating module 30 configured to create at least one window on the multi-screen, and the text is displayed in the window.

[0098] The second setting module 20 is also used to set the position of the window on the multi-screen display and to set the position of the text within the window, so that any one of the characters in the text is displayed on only one of the display screens.

[0099] The text includes a main body and an outline. The multi-screen text display device 400 also includes a drawing module 40. The drawing module 40 is used to draw the main body of the text in the window according to a preset text font size, and then draw the outline outside the main body according to a preset outline size.

[0100] like Figure 4 As shown, in another embodiment, a computer-readable storage medium 600 is provided, on which a computer program is stored, which, when executed by a processor, implements the multi-screen text display method as described in any of the above embodiments.
