Therefore, it is necessary to design different driving boards for different display screens. Increased configuration difficulty and configuration cost of the display and drive boards.
现有技术中，往往将画质文件以及屏参文件与显示设备的主程序一起打包存储在主板的存储芯片中，由于主程序与画质文件以及屏参文件打包在一起，导致针对不同的显示屏需要配置不同的主程序；为解决上述技术问题，将主程序与画质文件以及屏参文件分开保存于显示设备主板的存储装置中，在开机时调用该画质文件以及屏参文件，但由于主板烧录完成后，若采用同一主板驱动不同型号的显示屏，会导致主板中保存的画质文件以及屏参文件不能兼容多种型号的显示屏，即主板与显示屏的兼容性较低。In the prior art, the image quality file and the screen parameter file are packaged together with the main program of the display device in the memory chip of the motherboard, and the main program is packaged together with the image quality file and the screen file, resulting in different display. The screen needs to be configured with different main programs; in order to solve the above technical problems, the main program and the image quality file and the screen parameter file are separately stored in the storage device of the display device main board, and the image quality file and the screen parameter file are called when the device is turned on, but After the motherboard is burned, if the same motherboard is used to drive different models of the display, the image quality files and screen parameters saved in the motherboard will not be compatible with multiple models of display, that is, the compatibility between the motherboard and the display is low. .

When the power supply supplies the normal running cross current to the display A, the main board calls the screen reference file A. And the image quality file A provides the display A with a cross current current control signal of 99% of the pulse signal, so that the display screen A is normally displayed. When the motherboard is configured to use the television set B to drive the display screen B to operate normally, the motherboard Obtaining the screen file B and the image file B saved in the T-CON memory chip of the TV B, and providing the cross current control signal to the display B according to the screen file B and the image file B is 1%. The pulse signal causes the display B to display normally.
本实施例通过在显示屏设备启动时，获取时序电路板T-CON存储的第一屏参文件ID，在根据第一屏参文件ID获取时序电路板T-CON存储的第一屏参文件以及第一画质文件后，根据第一屏参文件以及第一画质文件驱动显示屏设备的显示屏运行。由于将驱动显示屏正常运行的第一屏参文件以及第一画质文件存储在时序电路板T-CON中，在显示设备启动时，通过控制主板调用该时序电路板T-CON中的第一屏参文件以及第一画质文件来驱动显示屏正常运行，因此使得同一主板与不同显示屏兼容，从而实现同一主板驱动不同显示屏运行。In this embodiment, when the display device is started, the first screen parameter file ID stored by the sequential circuit board T-CON is acquired, and the first screen parameter file stored in the sequential circuit board T-CON is obtained according to the first screen parameter file ID. After the first image quality file, the display screen of the display device is driven according to the first screen file and the first image file. Since the first screen parameter file and the first image quality file for driving the display screen are stored in the timing circuit board T-CON, when the display device is started, the first of the timing circuit boards T-CON is called by the control board. The screen file and the first image file drive the display to operate normally, thus making the same motherboard compatible with different displays, so that the same motherboard drives different display operations.
进一步的，基于步骤S30，该步骤S30具体包括：将第一屏参文件以及第一画质文件加载至主板，根据主板中的第一屏参文件以及第一画质文件驱动显示屏运行。Further, based on step S30, the step S30 specifically includes: loading the first screen file and the first image file to the motherboard, and driving the display according to the first screen file and the first image file in the motherboard.

The motherboard runs the display screen according to the first screen file and the first image file.
本实施例通过将第一屏参文件以及第一画质文件加载至主板，根据主板中的第一屏参文件以及第一画质文件驱动显示屏运行。由于T-CON存储芯片中存储的第一屏参文件以及第一画质文件是驱动显示运行的对应文件，通过将第一屏参文件以及第一画质文件自动加载到主板中，因此使得主板根据该第一屏参文件以及第一画质文件驱动该显示屏运行，不仅实现了同一主板驱动不同显示屏运行，而简化了同一主板驱动不同显示屏时切换主板中已存储的屏参文件以及画质文件的流程，提高了切换效率。In this embodiment, the first screen file and the first image file are loaded to the motherboard, and the display screen is driven according to the first screen file and the first image file in the motherboard. The first screen parameter file and the first image quality file stored in the T-CON memory chip are corresponding files for driving the display operation, and the first screen parameter file and the first image quality file are automatically loaded into the motherboard, thereby making the motherboard Driving the display screen according to the first screen parameter file and the first image quality file not only realizes the operation of different display screens of the same motherboard driver, but also simplifies switching the screen parameter files stored in the motherboard when the same motherboard drives different display screens. The process of drawing quality files improves the switching efficiency.

所述显示模块70，用于若第一屏参文件ID与第一画质文件ID不一致，则显示提示窗口，以提示用户选取与第一屏参文件ID一致的第三画质文件ID；The display module 70 is configured to: if the first screen file ID is inconsistent with the first image file ID, display a prompt window to prompt the user to select a third image file ID that is consistent with the first screen file ID;
在本实施例中，若该第一屏参文件ID与该第一画质文件ID不一致，表明该T-CON存储芯片中存储的第一画质文件有问题，该T-CON板向该主板发送如A1=1的提示消息，显示模块70根据该提示消息在该显示屏显示提示窗口或者在与该显示屏设备绑定的控制设备的显示界面上显示提示窗口，以提示用户选取与第一屏参文件ID一致的第三画质文件ID。In this embodiment, if the first screen file ID does not match the first image file ID, indicating that there is a problem with the first image file stored in the T-CON memory chip, the T-CON board is facing the motherboard. Sending a prompt message such as A1=1, the display module 70 displays a prompt window on the display screen according to the prompt message or displays a prompt window on the display interface of the control device bound to the display device to prompt the user to select and first The third image quality file ID with the same screen file ID.
所述加载模块80，用于根据第三画质文件ID加载第三画质文件ID对应的第三画质文件，并根据第一屏参文件ID加载第一屏参文件，以驱动显示屏运行。The loading module 80 is configured to load a third image quality file corresponding to the third image quality file ID according to the third image quality file ID, and load the first screen parameter file according to the first screen parameter file ID to drive the display screen to run. .
该提示窗口配有加载第三画质文件选项，可直接在该提示窗口选择加载第三画质文件选项，也可通过遥控方式选择加载第三画质文件选项，加载模块80根据该第三画质文件ID加载第三画质文件至T-CON存储芯片中，在确认加载后，主板直接重新启动，加载模块80加载T-CON存储芯片中的第三画质文件，以使主板驱动该显示屏重新运行。The prompt window is provided with the option of loading a third image quality file, and the option of loading the third image quality file can be directly selected in the prompt window, and the option of loading the third image quality file can be selected by remote control, and the loading module 80 according to the third drawing The quality file ID loads the third image quality file into the T-CON memory chip. After confirming the loading, the motherboard directly restarts, and the loading module 80 loads the third image quality file in the T-CON memory chip, so that the motherboard drives the display. The screen is re-run.
需要说明的是，在新增配屏项目后，所配主板***不需做变更则可直接点亮屏，而当画质调试确认完成后，则将该画质文件烧录进T-CON存储芯片中，则此屏的配屏工作即完成，大大缩短了开发周期和便利性。It should be noted that after the new screen matching project is added, the motherboard system can be directly illuminated without any changes, and when the image quality debugging is completed, the image quality file is burned into the T-CON storage. In the chip, the screen work of this screen is completed, which greatly shortens the development cycle and convenience.
本实施例通过判断第一屏参文件ID与时序电路板T-CON存储的第一画质文件对应的第一画质文件ID是否一致，若否，则显示提示窗口，以提示用户选取与第一屏参文件ID一致的第三画质文件ID，根据第三画质文件ID加载第三画质文件ID对应的第三画质文件，并根据第一屏参文件ID加载第一屏参文件，使得主板与显示屏进行配屏调试过程中，实现画质文件的更新更加简单。In this embodiment, by determining whether the first screen file ID is consistent with the first image file ID corresponding to the first image file stored by the sequential circuit board T-CON, if not, displaying a prompt window to prompt the user to select and The third image quality file ID corresponding to the file ID is matched, and the third image quality file corresponding to the third image quality file ID is loaded according to the third image quality file ID, and the first screen parameter file is loaded according to the first screen parameter file ID. In the process of debugging the main board and the display screen, it is easier to update the image quality file.
