Description

Technical Field

[0001] This utility model relates to the field of virtual display technology, and in particular to a virtual display system for commercial vehicles. Background Technology

[0002] Projection technology is a technique that uses light-emitting devices, magnifying devices, and image processing to ultimately display images on a physical plane. It is commonly used in slideshows and theatrical film screenings. Interactive technology typically refers to display or instruction devices responding to input or collected human body signals. It is commonly used in touchscreen displays and instrument displays. Virtual display technology represents a digital display method that creates one or more "virtual screens" on a physical screen or device through virtualization to achieve extended, replacement, or enhanced display effects. For example, a touchscreen can simulate keyboard display and operation, and can also enable drawing functions.

[0003] Currently, in the commercial vehicle sector, the widely used display methods include instrument displays, central control screen displays, and indicator light displays. Interaction methods include physical switches and touch switches. Therefore, during vehicle structural design, it is usually necessary to fix the instrument panel, central control screen, and various types of indicator lights in different positions within the vehicle and adjust the corresponding display angles according to the visibility range of each device.

[0004] Therefore, a virtual display system for commercial vehicles is proposed. Utility Model Content
