Description

The present invention relates to a vehicle display device, and more particularly to a multi-axis module for a vehicle display device and a vehicle display device.

There is a trend toward increasing display panel size, increasing technological maturity, and decreasing cost of manufacturing. The size of display panels of electronic devices is increasing, and the size of display panels of electronic devices for cars is also increasing. However, in order to save space in the car or to appropriately arrange various devices in the car, some manufacturers often install display panels of 4.3 inches or smaller than 4.3 inches in the car. Install an electronic device with a large-sized display panel in the car, adjust the angle of the display panel according to various needs (adjust forward/backward, left/right, up/down directions), or move the display panel horizontally or vertically. By rotating the display, it is possible to provide the user with a screen with a good viewing angle and a well-proportioned display. In order to provide a display panel that suits the visual and usage habits of different vehicles, occupants or drivers of different seats within the vehicle, there is a need to invent a display panel that is adjustable in angle.

In order to provide a display panel whose angle can be adjusted, it is necessary to attach a body axis module to the display panel.
