Abstract

[Summary] An image display system and method for displaying images of a means of transport are provided, relating to the field of image display technology. In the image display system and method, a first transmission path and a second transmission path are established between a control module and a display module. The control module compares first image data transmitted via the first transmission path with second image data transmitted via the second transmission path to determine if the first display content is inconsistent with the second display content, and thus can provide a reference base for subsequent processing by the control module (e.g., issuing an alarm prompt or correcting the second display content). This method makes it possible to determine whether the content displayed by the display module is accurate. If the content is inaccurate, subsequent processing can be performed in a timely manner to ensure the accuracy of the image displayed by the display module. This improves the safety of the vehicle during use.

Description

This application claims priority to Chinese Patent Application No. 202310342351.X, filed on March 28, 2023, entitled "IMAGE DISPLAY SYSTEM OF TRANSPORTATION MEANS AND IMAGE DISPLAY METHOD OF TRANSPORTATION MEANS," which is incorporated herein by reference in its entirety. This disclosure relates to the field of image display technology, and more particularly to image display systems and image display methods for means of transport. As people's demands for the driving experience of means of transport (e.g., vehicles, ships, aircraft, or trains) continue to grow, manufacturers of these means are increasingly replacing display modules within their vehicles with Liquid Crystal Displays (LCDs), for example, replacing mechanical dashboards in vehicles with LCD dashboards. In transportation systems, image data displayed by a display module is typically generated by a control module (e.g., the vehicle's head unit). As an example, consider a vehicle. An LCD dashboard may typically display dynamic data (e.g., vehicle speed or fuel level) and various indicator icons (e.g., front/rear fog indicators, low/high beam indicators, left/right turn indicators, ABS malfunction indicators, brake system malfunction indicators, and warning indicators for unfastened seatbelts). The image data displayed by the LCD dashboard is typically generated by the head unit and transmitted to the LCD dashboard. However, due to issues such as errors in image frame generation, image data corruption is unavoidable, and as a result, the LCD dashboard cannot display the correct image data. This poses a safety risk during vehicle operation. This disclosure provides an image display system and an image display method for a means of transport, enabling the resolution of the problem in related technologies where LCD dashboards cannot display accurate image data. The technical solution is described below. According to a first embodiment, an image display system for a means of transport is provided. The image display system includes a control module and a display module, wherein a first transmission path and a second transmission path are established between the control module and the display module, enabling bidirectional communication between the control module and the display module. For example, the first transmission path is used to transmit data or signals from the control module to the display module, and the second transmission path is used to transmit data or signals from the display module to the control module. Optionally, the first transmission path is used to transmit data or signals from the display module to the control module, and the second transmission path is used to transmit data or signals from the control module to the display module. The control module is configured to transmit first image data to the display module via a first transmission path, the first image data representing first display content. The image data generated by the control module may be considered as a single image frame, each image frame including an indicator icon layer and a real-time information layer. For example, the indicator icon layer includes various indicator icons such as front fog/rear fog indicators, low beam/high beam indicators, left turn/right turn indicators, ABS malfunction indicators, brake system malfunction indicators, and warning indicators for unfastened seat belts. The real-time information layer may display dynamic data related to the vehicle, such as the vehicle speed, fuel level in the fuel tank, and engine rotation speed. The display update cycle corresponding to the indicator icon layer is longer than the display update cycle corresponding to the real-time information layer. For example, the display update cycle corresponding to the indicator icon layer may be the blinking cycle of the icons, e.g., one second. The display update cycle of the real-time information layer is typically the frame duration. For example, when the refresh rate of the instrument cluster assembly is 60 Hz, the display update cycle of the real-time information layer is 1/60th of a second. For example, the control module is the head unit. The head unit generates first image data based on the current vehicle speed, the current fuel level, and an indicator that the driver's seatbelt is not fastened. The first display content corresponding to the first image data indicates what should be displayed on the instrument cluster assembly at that moment. In this case, the first display content should be the current vehicle speed, the current fuel level, and an icon indicating that the seatbelt is not fastened. The display module is configured to receive the first image data from the control module via a first transmission path. In some examples, the first image data received by the display module is consistent with the first image data generated by the control module. In some other examples, the first image data is corrupted during transmission via the first transmission
