Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to an OSD adaptive display method, device, equipment and medium based on screen resolution. Background Art

[0002] For large display screens such as LED display screens, the screen is usually composed of multiple display modules spliced ​​together. The number and splicing methods of different display modules determine the final screen resolution. For example, different splicing methods will produce different aspect ratios, such as wide screens with an aspect ratio greater than 1, vertical screens with an aspect ratio less than 1, and square screens with an aspect ratio equal to 1. The diversity of screen resolutions poses a great challenge to displaying OSD (On-Screen Display, screen display menus and information) on the display screen. For example, existing solutions usually rely on the use of dot matrix fonts to display OSD content. A significant limitation of the dot matrix font is that it presets fixed-size fonts and usually only supports 1 to 3 font sizes. This fixed character display method cannot flexibly cope with multiple screen resolutions. Due to the huge differences in screen resolutions caused by different splicing modes, it is impossible to flexibly and clearly display the OSD interface by simply relying on a fixed dot matrix font. This results in the OSD interface not being able to display normally at certain resolutions, or the display effect is extremely poor, which greatly affects the user experience.

[0046] Embodiment 1

[0047] The embodiment of the present invention provides an OSD adaptive display method based on screen resolution, which is applicable to a display screen system composed of multiple display modules, such as an LED display screen system. Figure 1 As shown, the display screen system includes, in addition to a target display screen for displaying images, a control module (such as a DSP or other ASIC) connected to the target display screen. The control module is also connected to a host computer or a microcontroller (such as a PC, a smart phone, a tablet computer, etc.) to receive information and data from the host computer or the microcontroller.

[0048] See also Figure 2 The OSD adaptive display method based on screen resolution specifically includes the following steps:

[0049] S1: Get the screen resolution of the target display;

[0050] S2: determining OSD frame information according to the screen resolution, wherein the OSD frame information at least includes an OSD display mode and an OSD resolution, wherein the display mode includes a row mode and a column mode;

[0051] S3: Obtain a preset character library file, wherein the preset character library file includes character libraries of several fonts of different sizes;

[0052] S4: Acquire a target font library matching the screen resolution from the preset font library file;

[0053] S5: The control module driving the target display screen generates an OSD interface according to the OSD framework information and the target font library and displays it on the target display screen.

[0054] Specifically, it is necessary to display an OSD interface on the target display screen. First, the screen resolution of the target display screen is obtained to understand the specific aspect ratio and pixel density of the screen. Figure 3 As shown, the screen resolution is obtained by the host computer or the microcontroller MCU. For example, the user calculates the screen resolution according to the splicing method of the target display screen and inputs it through the human-computer interaction interface of the host computer or the microcontroller. The host computer or the microcontroller sends the screen resolution to the control module (such as DSP) of the target display screen. Next, according to the obtained screen resolution, determine the appropriate OSD frame display mode and OSD resolution. Exemplarily, the display mode includes two options: row mode and column mode: when the aspect ratio of the screen is greater than or equal to 1, the row mode is adopted, that is, the information is arranged and displayed in rows; when the aspect ratio is less than 1, the column mode is adopted, and the information is arranged in columns. At the same time, it is also necessary to adjust the OSD resolution of the OSD according to the actual resolution of the screen to adapt it to the current screen. In addition, the preset font library file pre-sets several font libraries with different font sizes. For example, the preset font library file includes several font libraries, each of which is classified according to font size. For example, the first font library includes multiple fonts with a font size of 7×7 pixels, the second font library includes a font size of 12×12 pixels, and the third font library includes multiple fonts with a font size of 16×16 pixels. By establishing a preset font library file, adaptation from small screens to large screens and from low resolution to high resolution can be achieved, so that the most suitable font can be selected for display on screens with different resolutions. For example, Figure 3As shown, the preset font file can be stored in a USB device. After the screen resolution is obtained, the host computer or microcontroller determines the target font that matches the screen resolution, and sends a font call instruction to the control module to drive the control module to import the matching target font from the USB device, ensuring that the selected font size and style can be clearly displayed at the current screen resolution, without characters being too large to cause information overflow, or fonts being too small to affect readability. Finally, the control module calls the corresponding UI tool to generate an OSD interface image based on the obtained OSD framework information and the target font, and drives the target display screen to display the OSD interface. These steps ensure that the OSD interface can be displayed correctly on display screens with different resolutions, the information is clear and readable, and the user experience is good.

[0055] In one embodiment, the target display screen is composed of a plurality of display modules, and obtaining the resolution of the target display screen includes:

[0056] The resolution of the target display screen is obtained according to the number and splicing method of the display modules.

[0057] In this embodiment, the target display screen is composed of multiple display modules spliced ​​together. This spliced ​​display screen is widely used in large display devices. By combining several display modules (hereinafter referred to as modules) together, a screen of any size and resolution can be formed. In order to accurately generate and display the OSD interface, it is necessary to first obtain the screen resolution of the entire spliced ​​target display screen. Specifically, each module usually has a fixed resolution, expressed as the width and height of the module (for example, the resolution of a module may be 192×192 pixels). When splicing, the resolution of the entire screen can be obtained by combining these modules in a certain arrangement (such as the number of horizontal and vertical directions). In order to calculate the resolution of the target display screen, two key parameters must be known first: the number of modules and their arrangement or splicing method. Exemplarily, the target display screen is composed of 3 display modules arranged horizontally, 2 display modules arranged vertically, and the resolution of each module is 192×192 pixels. Then the resolution of the entire target display screen can be calculated by the following formula:

[0058] Horizontal resolution: the horizontal number of modules × the width of each module = 3 × 192 = 576 pixels.

[0059] Vertical resolution: vertical number of modules × height of each module = 2 × 192 = 384 pixels.

[0060] Therefore, the resolution of the entire target display is 576×384 pixels. It is also worth noting that different splicing methods will affect the aspect ratio of the screen and its overall resolution. For example, an increase in the number of modules or a change in the arrangement (such as 4 modules horizontally and 3 modules vertically) will change the screen resolution of the entire target display. By accurately obtaining this screen resolution, the appropriate OSD framework (such as row mode or column mode) is further determined, and the font suitable for the resolution is selected from the preset font file, accurate display can be achieved, ensuring that no matter how the scale and arrangement of the screen splicing, the information can be correctly displayed according to the spliced ​​screen resolution, thereby improving the applicability of the display in large-scale and complex scenarios.

[0061] In one embodiment, determining OSD frame information according to the screen resolution, wherein the OSD frame information at least includes an OSD display mode and an OSD resolution, comprises:

[0062] Determining the aspect ratio of the target display screen according to the screen resolution;

[0063] determining the display mode according to the aspect ratio;

[0064] Get the preset OSD maximum resolution;

[0065] When the screen resolution is greater than or equal to the preset OSD maximum resolution, the OSD resolution is equal to the preset OSD maximum resolution;

[0066] When the screen resolution is less than the preset OSD maximum resolution, the OSD resolution is determined according to the screen resolution and the display mode, and the OSD resolution is less than or equal to the screen resolution.

[0067] Preferably, determining the display mode according to the aspect ratio comprises:

[0068] When the aspect ratio is greater than or equal to 1, the display mode is a row mode, and the OSD frame is configured to contain at least one row of information units and at most N rows of information units, wherein N is determined according to the height of the target display screen and the height of the information unit;

[0069] When the aspect ratio is less than 1, the display mode is a column mode, and the OSD frame is configured to include at least one column of information units, and at least M columns of information units, wherein M is determined according to the width of the target display screen and the width of the information unit;

[0070] The information unit includes at least one character.

[0071] First, the aspect ratio of the target display screen can be determined according to the screen resolution of the target display screen. The aspect ratio refers to the ratio of the width to the height of the screen, which is used to determine the shape of the display screen and its suitable display mode. Generally speaking, a display screen with an aspect ratio greater than 1 is usually called a wide screen, while a screen with an aspect ratio less than 1 is called a vertical screen. Exemplarily, if the screen resolution of the target display screen is 1920×1080 pixels, then its aspect ratio is 1920:1080, which is approximately equal to 16:9, which is greater than 1, indicating that the screen is a wide screen. On the other hand, if the resolution is 1080×1920, the aspect ratio is 9:16, which is less than 1, indicating that the screen is a vertical screen. In this embodiment, the selection of the OSD display mode is based on the aspect ratio of the target display screen. When the aspect ratio is greater than or equal to 1, the OSD will adopt the "row mode"; when the aspect ratio is less than 1, the OSD will adopt the "column mode". Among them, the row mode means that the OSD content is arranged in rows to adapt to the horizontally longer display screen. The row mode is suitable for displaying more horizontal information, such as multiple characters or content units can be accommodated in one line. The column mode means that the OSD content is arranged in columns to adapt to the vertically taller screen to ensure that the content unit can be displayed vertically and avoid horizontal crowding.

[0072] In order to optimize the display effect, preferably, a preset OSD maximum resolution is set to prevent the OSD from occupying too large a screen area at a very high screen resolution and affecting the display of other content. The preset OSD maximum resolution can be set according to display requirements and actual application scenarios, and is not limited here. For example, the preset OSD maximum resolution is 1920×1080. No matter how high the resolution of the target display is, the OSD resolution will not exceed this value, ensuring that the OSD content can be displayed in an appropriate size and will not be displayed too large due to the high screen resolution.

[0073] After determining the screen resolution and display mode, the next step is to calculate the OSD resolution. The determination of OSD resolution can be divided into two cases:

[0074] When the screen resolution of the target display is greater than or equal to the preset OSD maximum resolution, the OSD resolution will be equal to this maximum resolution. For example, if the screen resolution of the target display is 3840×2160 pixels and the OSD maximum resolution is preset to 1920×1080 pixels, the OSD resolution will be 1920×1080 pixels.

[0075] When the screen resolution of the target display is lower than the preset OSD maximum resolution, the OSD resolution will be adjusted according to the screen resolution and display mode. At this time, the OSD resolution will be less than or equal to the screen resolution, ensuring that the OSD content will not exceed the screen boundary and can be clearly displayed on the display with a smaller resolution. For example, assume that the resolution of the target display is 1280×720 pixels, and the OSD maximum resolution is 1920×1080 pixels. In this case, the OSD resolution will be set to no more than 1280×720 pixels to ensure that the OSD can be fully displayed on the target screen without exceeding the screen boundary. In addition, when determining the OSD resolution, the OSD display mode will also affect the final display effect. For example, in row mode, the OSD will be displayed in a row arrangement, so the OSD frame can accommodate at least one row of information units (such as characters) and can display at most N rows of information units. N is calculated by dividing the height of the target display by the height of the information unit (such as the height of one character). Similarly, in column mode, the OSD frame can accommodate at least one column of information units and can display at most M columns of information units. M is calculated as the width of the target display divided by the width of the information unit. Therefore, the OSD resolution will change according to the number of rows or columns set by the OSD frame. In this way, the OSD frame and resolution are automatically adjusted according to the resolution, aspect ratio and display mode of different displays, ensuring that the OSD content can be displayed in the best way on displays with different resolutions, improving the flexibility of OSD display and user experience.

[0076] In one embodiment of the present invention, when the screen resolution of the target display screen is less than the preset OSD maximum resolution, the OSD resolution needs to be adjusted according to the screen resolution and display mode to ensure that the OSD content can be displayed in the best way on display screens of different sizes. The solution determines the final OSD resolution by selecting a suitable OSD frame style.

[0077] When the screen resolution is less than the preset OSD maximum resolution, determining the OSD resolution according to the screen resolution and the display mode includes:

[0078] Determine a plurality of different OSD frame styles based on the display mode, wherein different OSD frame styles have different numbers of rows or columns;

[0079] The OSD resolution is determined by selecting one of the OSD frame styles according to the screen resolution.

[0080] First, based on the display mode (row mode or column mode), several different OSD frame styles can be preset. These OSD frame styles are mainly realized by setting different numbers of rows or columns to adapt to display screens of different sizes and shapes. For example, in row mode, an OSD frame with different numbers of rows such as 1 row, 2 rows, and 3 rows can be set; in column mode, an OSD frame with different numbers of columns such as 1 column, 2 columns, and 3 columns can be set. These different frame styles provide a flexible arrangement for OSD content to ensure that information can adapt to screens with different resolutions. The available OSD frame styles are determined by the screen resolution of the target display screen. In row mode, a suitable number of rows is selected according to the height of the display screen and the height of each row; in column mode, a suitable number of columns is selected according to the width of the display screen and the width of each column. Then, from the preset OSD frame styles, a frame style that matches the screen resolution is selected to determine the final OSD resolution. Exemplarily, the resolution of the target display screen is 800×600 pixels, the preset OSD maximum resolution is 1920×1080 pixels, and the OSD display mode is row mode. In this case, since the screen resolution is less than the maximum resolution, you need to select a suitable style from the preset OSD frame styles. Assuming that the height of each line is 50 pixels, the number of lines that can be accommodated is 600÷50=12 lines according to the height of the display screen (600 pixels). Assuming that the OSD frame style includes 2 lines, 6 lines, 12 lines, and 24 lines, you can select a 12-line OSD frame style and set the OSD resolution of the 12-line style to 800×600 pixels to ensure that the OSD content can fully adapt to the screen resolution. In addition, you can also select a 6-line OSD frame style and set the OSD resolution of the 12-line style to 800×300 pixels, so that the OSD interface only needs to occupy half of the screen.

[0081] In addition, if the OSD interface contains a lot of information, and the currently displayed OSD frame can only accommodate part of it, a cyclic switching method can be used to display different parts of the information on the screen in sequence. This cyclic switching mechanism can be flexibly configured according to the actual usage scenario. For example, the display time of each batch of content can be set, and when a group of content is displayed, it automatically switches to the next group of content and displays it. Users can also manually switch the displayed content by pressing buttons, etc., providing more control options. This method ensures that even at lower resolutions, the OSD interface can still fully display all necessary information without information being truncated or omitted due to screen space limitations.

[0082] Preferably, the specific OSD frame style selection process can be preset in a control module such as a DSP according to different screen resolutions. The control module can automatically select the most suitable OSD frame style according to parameters such as the resolution, aspect ratio, and display mode of the target display screen, such as the setting of a row mode or a column mode, the number of rows or the number of columns, etc. In addition, relevant instructions can also be transmitted to the control module by a host computer or an MCU (microcontroller) so that the user can dynamically adjust the display mode of the OSD framework according to actual needs. The host computer or the MCU can also flexibly transmit different configuration parameters according to the application scenario, and the drive control module adjusts the layout and content display mode of the OSD framework according to the real-time situation. Through this flexible control method, the OSD interface can adapt to various resolutions and display requirements, ensuring that on screens with different resolutions, the content can be presented in the best way.

[0083] When the OSD frame and target font are determined, the appropriate OSD frame style (such as row mode or column mode) and the matching target font are selected according to the screen resolution. Next, the control module (such as DSP) will generate a specific OSD interface based on these preset information. This interface usually includes content such as device status, operation prompts or menu information. Then, the control module converts this information into display data and sends it to the LED screen for display through the driver.

[0084] In summary, the screen resolution-based OSD adaptive display method provided by the embodiment of the present invention realizes flexible OSD display on display screens with different resolutions, and solves the problem in the prior art that the OSD interface cannot normally adapt to various screen resolutions due to the limitations of the font library, etc. The method of the present invention determines and imports the OSD framework and font library that match the screen resolution according to different screen resolutions, so that the OSD interface can be displayed clearly and stably on any spliced ​​screen or display screen with non-standard resolution. Because the OSD interface can not only display the current status information of the device, such as working mode, playback content, etc., but also interact with the user to provide device control functions. Users can easily view the operating status of the device or perform operations through the OSD interface, which greatly improves the convenience of device operation and user experience.
