[0031] In the field of LED display, the performance and flexibility of the sending card, as a key component connecting the control system and the LED display, directly affect the application scope and display effect of the LED display. Currently, the sending cards on the market generally adopt a default maximum load design, that is, within a specific maximum load width and height range, users can set a custom resolution that does not exceed this range as needed. Among them, the maximum load of the sending card refers to the total number of pixels that the sending card can control, and the resolution is the product of the horizontal and vertical pixel numbers on the LED display. The maximum load of the sending card limits the maximum resolution that the LED display can achieve.

[0032] However, LED display scenes are often changeable and irregular. Different scenes correspond to different display screen sizes and different display resolution requirements, and the actual requirements often exceed the maximum load of the sending card. Therefore, the traditional solution is to achieve the adaptation of ultra-wide and ultra-high scenes through software customization. Basically, a specific software version is designed for each required display scene (usually one display scene corresponds to one display screen, and each display screen corresponds to one display resolution).

[0033] Specifically, designing a specific software version in a traditional solution usually includes the following steps:

[0034] 1. Debug screen parameters: Adjust and optimize screen parameters according to the display requirements of the required display scene to ensure that the display effect meets expectations.

[0035] 2. Compiler: Use specific programming languages ​​and tools to write the debugged screen parameters into program codes, compile them, and generate executable software programs.

[0036] 3. Burn the program: Burn the compiled program into the sending card so that the sending card can control the LED display to display according to the predetermined resolution and effect.

[0037] 4. Self-check program: After burning the program, perform a self-check to ensure that the program has no obvious errors and can run normally.

[0038] 5. Submit the program for testing: Submit the program that has passed the self-test to the testing team in preparation for more comprehensive testing.

[0039] 6. Test program: The test team conducts detailed functional and performance tests on the program to ensure that the program can run stably under various conditions and meet the requirements of the display scenario.

[0040] 7. Release the program: After passing the test, the program will be officially released for users to download or automatically update.

[0041] 8. Upgrade program: The user end upgrades the existing software according to the released new version to obtain better display effects or new functions.

[0042] 9. Version management: During the entire process, each version of the program needs to be strictly managed and detailed information of each version needs to be recorded, including modification content, release date, applicable scenarios, etc., for easy tracking and maintenance.

[0043] It can be seen that the traditional solution has the following problems:

[0044] 1. Chaotic version management: With the increase in display scenarios, each display scenario corresponds to a version of the software, resulting in a sharp increase in the number of versions, making management complicated and the workload increasing.

[0045] 2. Large R&D workload: Each new display scenario requires redesigning and testing the software, which increases the workload of the R&D team and takes a long time.

[0046] 3. High testing cost: Each version needs to go through a complete testing process, which increases testing cost and time.

[0047] 4. Upgrade risk: On-site upgrade procedures may fail due to compatibility issues or other technical obstacles, increasing the risk.

[0048] 5. Increased user complexity: Users need to adapt to different versions of software, and may encounter various problems during the upgrade process, which increases the complexity of user use.

[0049] In order to solve the problem that the display resolution of the display screen exceeds the maximum load of the sending card, different software programs need to be additionally customized to configure the display control parameters. In the embodiment of the present application, a parameter configuration program is set in the sending card, so that after the sending card receives the control parameters based on the debugging of different display screens, the parameter configuration program can be used to automatically obtain the display control parameters adapted to the different display screens according to the debugged control parameters. Thus, based on one parameter configuration program, the configuration of the display control parameters of different display screens is realized. There is no need to additionally customize different software programs to configure the display control parameters for different display screens, and there is no need for users to develop and test a large number of different software programs, thereby reducing the workload of after-sales processing of a large number of different software programs. There is no need for users to adapt to a large number of different versions of software programs, thereby reducing the complexity of user use.

[0050] The application scenario of the display screen control parameters of the embodiment of the present application includes a host computer, a sending card and a display screen; the host computer is connected to the sending card via Ethernet or other interfaces, and the sending card is directly connected to the display screen or connected to the display screen via a pick-up card to control the display screen to display. The display screen control parameter configuration method of the embodiment of the present application is executed by the sending card, and the sending card can be implemented by software and / or hardware.

[0051] The following will be combined with the attached Figure 1 to Figure 2 , a detailed introduction is given to the display screen control parameter configuration method provided in an embodiment of the present application.

[0052] The display screen control parameter configuration method provided in the embodiment of the present application is applied to a sending card; the method comprises the following steps:

[0053] S101: Receive a first control parameter sent by a host computer; the first control parameter is used to indicate a control parameter obtained after the host computer debugs the current display screen; the current display screen is a display screen that the current sending card needs to adapt to.

[0054] S102: Obtain a second control parameter according to the first control parameter; the second control parameter is used to indicate a maximum load parameter of the sending card.

[0055] S103: configuring display screen control parameters based on the first control parameter and the second control parameter.

[0056] In the embodiment of the present application, for a display screen whose display resolution exceeds the maximum load of the sending card, the host computer sends the first control parameter obtained after debugging different display screens to the sending card, so that the sending card can automatically obtain the second control parameter including the maximum load parameter of the sending card based on the built-in parameter configuration program and the first control parameter, and then automatically configure the control parameters of different display screens based on the first control parameter and the second control parameter, thereby eliminating the need to customize different software programs to configure the display screen control parameters for different display screens. Moreover, the present application only needs to develop and manage the one parameter configuration program on the sending card, thus avoiding a large amount of development and testing work on different software programs, reducing the complexity of software management, and reducing the workload of after-sales processing of multiple software programs. There is no need for users to adapt to a large number of different versions of software programs, thereby reducing the complexity of user use.

[0057] It can be understood that in the embodiment of the present application, a parameter configuration program is provided in the sending card. The following embodiment of the present application uses the parameter configuration program as the execution body to illustrate the various steps of the display screen control parameter configuration method.

[0058] For step S101, a first control parameter sent by the host computer is received; the first control parameter is a control parameter obtained after the host computer debugs the current display screen; the current display screen is the display screen that the sending card currently needs to adapt.

[0059] Specifically, the host computer sends a test signal to the display screen, and obtains a display effect on the display screen; according to the display effect, the control parameters are debugged on the host computer until the best display effect is achieved on the display screen. At this time, the host computer can obtain the first control parameter after debugging, and send the first control parameter to the sending card through the host computer.

[0060] The first control parameter is used to indicate the main display parameter of the display screen for displaying the digital image signal.

[0061] The host computer refers to the computer system used for monitoring, control and data processing in the display control parameter system. It is located at the upper layer of the entire system and is responsible for communicating with the lower computer (such as the sending card), receiving and sending data, performing high-level processing and decision-making, and providing a user interface to the operator. The host computer can be a dedicated hardware and software system or a specific software application running on a general-purpose computer. For example, the host computer can be a computer device such as a computer or a tablet.

[0062] The maximum load parameter of a sending card usually refers to the number of pixels of the display screen that the sending card can control.

[0063] In an optional embodiment, the first control parameters include: effective pixel width, effective pixel height, horizontal synchronization width, vertical synchronization width, horizontal front edge, horizontal back edge, vertical front edge and vertical back edge, so as to obtain the second control parameters and configure the display screen control parameters through the above parameters.

[0064] Among them, the effective pixel width refers to the number of horizontal pixels actually used to display the image content on the display screen, and this value determines the horizontal resolution of the display screen. The effective pixel height refers to the number of vertical pixels actually used to display the image content on the display screen, and this value determines the vertical resolution of the display screen. The horizontal synchronization width refers to the duration of the horizontal synchronization pulse, which is used to synchronize the refresh of the display screen at the end of each horizontal scan line. The vertical synchronization width refers to the duration of the vertical synchronization pulse, which is used to synchronize the refresh of the display screen after all lines are refreshed. The horizontal front porch refers to a blank period of time before the image display starts and after the horizontal synchronization pulse ends in the horizontal scan line, which is usually used to clear the residual influence of the previous line. The horizontal back porch refers to a blank period of time after the image display ends and before the next horizontal synchronization pulse starts in the horizontal scan line, which is also used to clear the image afterglow and prepare for the next image line. The vertical front porch refers to a blank period of time before the image display starts and after the vertical synchronization pulse ends in the vertical scan frame. The vertical back porch refers to a blank period of time after the image display ends and before the next vertical synchronization pulse starts in the vertical scan frame.

[0065] In the embodiment of the present application, the effective pixel width, effective pixel height, horizontal synchronization width, vertical synchronization width, horizontal front edge, horizontal back edge, vertical front edge and vertical back edge are used as the main display parameters for displaying the digital image signal on the current display screen. The display screen control parameters are obtained based on the above parameter configuration, so that the image displayed based on the display screen control parameters is adapted to the current display screen.

[0066] In an optional embodiment, the first control parameter also includes a display screen field frequency, so as to calculate the control field frequency of the sending card through the display screen field frequency. The display screen field frequency is the number of images that the display screen can display per second, which determines the speed of screen content refresh.

[0067] In another optional embodiment, the first control parameter further includes minimum pixel clock, horizontal polarity, vertical polarity, total pixel clock, etc., so as to test whether the configured display screen control parameters are valid according to the minimum pixel clock, horizontal polarity, vertical polarity, and total pixel clock. Among them, the minimum pixel clock refers to the minimum pixel clock frequency at which the display screen can work normally, the horizontal polarity refers to the scanning direction of the pixels of the display screen in the horizontal direction (from left to right); the vertical polarity refers to the scanning direction of the pixels of the display screen in the vertical direction (from top to bottom), and the total pixel clock refers to the actual frequency of the pixel clock of the display screen when it is working.

[0068] For step S102, a second control parameter is obtained according to the first control parameter; the second control parameter is the maximum load parameter of the sending card.

[0069] In an optional embodiment, the second control parameter includes total pixel width and total pixel height; the total pixel width is the maximum pixel that the sending card can transmit in the horizontal direction; the total pixel height is the maximum pixel that the sending card can transmit in the vertical direction. Figure 2 The step of obtaining the second control parameter according to the first control parameter in step S102 includes:

[0070] S1021: Obtain the total pixel width according to the effective pixel width, the horizontal synchronization width, the horizontal front edge, and the horizontal back edge.

[0071] In an optional embodiment, the sum of the effective pixel width, horizontal synchronization width, horizontal front edge and horizontal back edge is used as the total pixel width of the sending card. The specific calculation formula is: total pixel width = effective pixel width + horizontal synchronization width + horizontal front edge + horizontal back edge.

[0072] It should be understood that the total pixel width can also be calculated by adding the sum of the effective pixel width, horizontal synchronization width, horizontal front edge and horizontal back edge, plus a preset value, as the total pixel width of the sending card to ensure that the configured total pixel width has sufficient pixel transmission capacity in the horizontal direction to adapt to the current display screen.

[0073] S1022: Obtain a total pixel height according to the effective pixel height, the horizontal synchronization height, the vertical front edge, and the vertical back edge.

[0074] In an optional embodiment, the sum of effective pixel height, horizontal synchronization height, vertical front edge and vertical back edge is used as the total pixel height of the sending card. The specific calculation formula is: total pixel height = effective pixel height + vertical synchronization width + vertical front edge + vertical back edge.

[0075] It should be understood that the total pixel height can also be calculated by adding the sum of the effective pixel height, horizontal synchronization height, vertical front edge and vertical back edge, plus a preset value, as the total pixel height of the sending card to ensure that the configured sending card has sufficient pixel transmission capacity in the vertical direction to adapt to the current display screen.

[0076] The embodiment of the present application obtains the total pixel width according to the effective pixel width, horizontal synchronization width, horizontal front edge and horizontal back edge, and obtains the total pixel height according to the effective pixel height, horizontal synchronization height, vertical front edge and vertical back edge, so that the pixel transmission capability of the sending card in the horizontal and vertical directions can be matched with the display resolution of the display screen. Moreover, compared with the method of sending the total pixel width and total pixel height by the host computer, the total pixel width and total pixel height are determined by the sending card, which can reduce the amount of parameter sending and improve data sending efficiency and data accuracy.

[0077] In an optional embodiment, the first control parameter further includes the display screen field frequency; the second control parameter further includes the control field frequency of the sending card; step S102, the step of obtaining the second control parameter according to the first control parameter, further includes:

[0078] Step S1023: Obtain the control field frequency of the sending card according to the display screen field frequency and the total pixel height.

[0079] Among them, the display field frequency is the number of images that the display can display per second, which determines the speed at which the screen content is refreshed.

[0080] The control field frequency of the sending card is the number of images that can be displayed on the display screen per second determined by the sending card in the absence of an external synchronization signal.

[0081] The product of the display screen field frequency and the total pixel height is used as the control field frequency of the sending card. The specific calculation formula is: control field frequency of the sending card = display screen field frequency * total pixel height.

[0082] The embodiment of the present application obtains the control field frequency of the sending card according to the field frequency of the display screen and the total pixel height, so that the image controlled by the sending card to be displayed can match the image that can be displayed on the current display screen, so as to display the image as much as possible.

[0083] For step S103: configure the display screen control parameters according to the first control parameter and the second control parameter.

[0084] It is understandable that the first control parameter and the second control parameter can be directly applied to the sending card to obtain the display screen control parameter, that is, the first control parameter and the second control parameter are used as the display screen control parameters of the sending card.

[0085] In an optional embodiment, the display screen control parameter configuration method further includes the steps of:

[0086] S104: Acquire the maximum hardware load parameters supported by the hardware of the sending card; the maximum hardware load parameters include the total hardware pixel width and the total hardware pixel height, wherein the total hardware pixel width is greater than the total hardware pixel height;

[0087] S105: If the total pixel height is greater than the hardware total pixel height, the hardware total pixel width is used to match the total pixel height, so as to transmit the vertical pixels through the horizontal pixel transmission channel on the sending card hardware, and the hardware total pixel height is used to match the total pixel width, so as to transmit the horizontal pixels through the vertical pixel transmission channel on the sending card hardware.

[0088] In the embodiment of the present application, when the total pixel height is greater than the hardware total pixel height, the hardware total pixel width is used to match the total pixel height, and the hardware total pixel height is used to match the total pixel width, which can ensure that the sending card can support the configured display control parameters in hardware and avoid display control abnormalities.

[0089] It is understandable that if the total pixel height is less than the total pixel height of the hardware, it means that the current sending card can support the configured display control parameters in hardware and no adjustment is required. If the total pixel width is greater than the total pixel width of the hardware, it means that the current sending card cannot support the configured display control parameters in hardware and the sending card issues a configuration error prompt.

[0090] In an optional embodiment, the display screen control parameter configuration method further includes the steps of:

[0091] S106: According to the display screen control parameters, the display screen is controlled to display, and the total pixel clock, the total number of pixels, the horizontal limit or the vertical limit are obtained by testing, and the total pixel clock, the total number of pixels, the horizontal limit or the vertical limit of the first control parameter are matched to determine the validity of the configured display screen control parameters.

[0092] It is understandable that if the total pixel clock, total pixel count or maximum width and height obtained by the test are different from the total pixel clock, total pixel count or maximum width and height of the first control parameter, the validity of the configured display screen control parameters is determined. If the total pixel clock, total pixel count or maximum width and height obtained by the test are different from the total pixel clock, total pixel count or maximum width and height of the first control parameter, the configured display screen control parameters are determined to be invalid, and the sending card issues a configuration error prompt.

[0093] The following is a specific example to illustrate the display screen control configuration method of the present application:

[0094] The host computer sends a test signal to the display screen, and the display effect is obtained on the display screen; according to the display effect, the display screen parameters are debugged on the host computer until the best display effect is achieved on the display screen. At this time, the debugged display screen parameters can be obtained on the host computer, and the first control parameters are sent to the sending card through the host computer. Among them, the first control parameters include effective pixel width, effective pixel height, horizontal synchronization width, vertical synchronization width, horizontal front edge, horizontal back edge, vertical front edge, vertical back edge, display screen field frequency, minimum pixel clock, horizontal polarity, vertical polarity and total pixel clock.

[0095] The sending card uses the sum of the effective pixel width, the horizontal synchronization width, the horizontal front edge and the horizontal back edge as the total pixel width of the sending card, and uses the sum of the effective pixel height, the horizontal synchronization height, the vertical front edge and the vertical back edge as the total pixel height of the sending card; and uses the product of the field frequency of the display screen and the total pixel height as the control field frequency of the sending card, that is, the sending card obtains the second control parameter according to the first control parameter, wherein the second control parameter includes the total pixel width of the sending card, the total pixel height of the sending card and the field frequency of the sending card.

[0096] Apply the first control parameter and the second control parameter to the sending card to configure the display screen control parameters of the sending card; perform a test according to the display screen control parameters configured for the sending card, and control the display screen to display. If the difference between the total pixel clock, total pixel number, or maximum width and height obtained by the test and the total pixel clock, total pixel number, or maximum width and height of the first control parameter is within the preset range, the validity of the configured display screen control parameters is determined. When the validity is passed, the final display screen control parameters are obtained.
