[0056] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0057] Figure 1 This is a diagram illustrating the vehicle display device of this embodiment. Figure 2 This is a diagram of the variable display providing a user experience in this embodiment.

[0058] The direction in which a vehicle moves forward is called the forward direction, and the direction in which a vehicle moves backward is called the backward direction.

[0059] The vehicle display device can be installed on the vehicle's dashboard 1.

[0060] Multiple displays can be installed on the vehicle's dashboard 1.

[0061] The form of at least one of the plurality of displays can be changed.

[0062] The plurality of displays may include a driver's seat display 2 located in front of the driver's seat, a passenger seat display 3 located in front of the passenger seat, and a variable display 4 located between the driver's seat display 2 and the passenger seat display 3.

[0063] The form of the driver's seat display 2 can remain unchanged.

[0064] The passenger-side display 3 and the variable display 4 can change their form according to the vehicle's status or the passengers' situation.

[0065] Figure 1 (a) is a diagram of the driving mode when the passenger is driving the vehicle. Figure 1 (b) is a diagram of a special mode when the vehicle or passengers are in a special situation. Figure 1 (c) is a diagram of the parking mode when the vehicle is parked.

[0066] Driving mode can be the mode in which the driver holds the steering wheel and drives the vehicle.

[0067] Examples of special modes could be parking modes where the vehicle is temporarily stopped or autonomous driving modes where the vehicle is fully automated.

[0068] Special modes can be any mode other than driving mode and parking mode, or they can be non-driving modes.

[0069] Parking mode can be either the vehicle parking mode or the non-driving mode.

[0070] The driver's seat display 2 can be a display that conveys information to the driver.

[0071] The driver's seat display 2 can be a display whose shape does not change regardless of the vehicle's mode.

[0072] The co-driver display 3 can be a PIP (Passenger Information Display) or a CDD (Co-driver Display) that transmits information to the co-driver.

[0073] In driving mode and special modes, the upper height of the passenger seat display 3 can be lowered; in parking mode, the upper height of the passenger seat display 3 can be raised. In parking mode, the upper height of the passenger seat display 3 can be higher than that in driving mode or special modes.

[0077] In driving mode, the variable display 4, such as Figure 1 As shown in (a), it can be either the outward bending mode (Bend-out Mode) of the flexible display 10 or the portrait mode (Portrait Mode) of the flexible display 10.

[0078] In driving mode, the flexible display 10 can be bent so that the lower part of the flexible display 10 protrudes into the vehicle interior.

[0079] In driving mode, the top of the variable display 4 can be lowered, while in special mode or parking mode, the top of the variable display 4 can be higher.

[0080] In driving mode, the top height of the variable display 3 can be lower than the top height of the variable display 4 in special mode or parking mode.

[0081] In driving mode, the top of the variable display 4 is positioned low, ensuring ample visibility for the driver and other passengers.

[0082] When the vehicle is not in driving mode, the variable display 4 can be in an upward moving mode (Move-up Mode) where the flexible display 10 rises when it is in driving mode, or in a rotating mode or landscape mode where the flexible display 10 rotates horizontally.

[0083] In special modes, such as the variable display 4 Figure 1 As shown in (b), it can be Move-up Mode, Rotate Mode, or Landscape Mode.

[0084] In parking mode, the variable display 4, such as Figure 1 As shown in (c), it can be a move-up mode, a rotate mode, or a landscape mode.

[0085] The variable display 4 may include a bending mechanism that enables the flexible display 10 to bend and a rotation mechanism that enables the flexible display 10 to rotate to landscape or portrait mode.

[0086] A rear protrusion 1a may protrude from the instrument panel 1 of the vehicle. The rear protrusion 1a may protrude from the instrument panel 1 of the vehicle into the passenger compartment.

[0087] When the flexible display 10 is in an outward bending mode, the upper surface of the rear protrusion 1a, such as Figure 1 As shown in (a), it can be covered by the flexible display 10.

[0088] When the flexible display 10 is in the upward moving mode, the upper surface of the rear protrusion 1a, as... Figure 1 (b) or Figure 1 As shown in (c), it can be exposed to the vehicle compartment.

[0089] like Figure 2 As shown, the variable display 4 can provide a user experience (UX) of various information to help driving, or provide an entertainment user experience in a way similar to a mobile phone experience, or provide a user experience that enables efficient work while parked.

[0090] like Figure 2 As shown in (a), the variable display 4 can provide a navigation view that presents map information ahead of the driving path in an easy-to-view portrait format.

[0091] like Figure 2As shown in (b), the variable display 4 can provide a mobile short-form view that offers the best consumption experience for mobile short-form video content.

[0092] like Figure 2 As shown in (c), the variable display 4 can provide a mobile office environment experience such as instant video conferencing.

[0093] like Figure 2 As shown in (d), the variable display 4 can provide passengers with an extended content experience.
