[0179] Another example of a display (2") is that when at the third height, an image can be output through an area (B) facing the passenger compartment and an area (A) facing the prism entrance surface (31) of the prism screen (3).

[0180] When the display (2") is in the third position (P3), the passenger can obtain an image through the area (B) facing the car interior among the emission surface (21) of the display (2") and can obtain an image through the prism screen (3).

[0181] When the display (2") is in the third position (P3), the display (2") and the prism screen (3) can provide a full display.

[0182] The driving mechanism (6') can bend or unfold the display (2").

[0183] The driving mechanism (6') can unfold the display (2") to the first position (P1) or rotate it to the second position (P2) or third position (P3).

[0184] The display (2") can be positioned horizontally or inclined at a predetermined angle in the front-back direction when in the first position (P1). The front end height of the display (2") and the rear end height of the display can be different.

[0185] Among the front and rear ends of the display (2"), the rear end can be closer to the vehicle interior.

[0186] The driving mechanism (6') can drive the display (2") so that the display (2") slides while bending.

[0187] An example of a driving mechanism (6') may include a motor (61'), a driving gear (62') connected to the motor (61'), and a driven gear (not shown) to which the driving gear (62') is engaged.

[0188] The motor (61') can be placed on the dashboard (4) or the guide (66). The motor (61') can slide the display (2") while in a fixed position.

[0189] An example of a drive gear (62') may be a pinion connected to the rotational shaft of a motor (61').

[0190] Another example of a drive gear (62') may include a power transmission gear connected to the rotational shaft of a motor (61') and a pinion meshed with each of the power transmission gear and the driven gear.

[0191] An example of a driven gear could be a rack placed on the display (2") or the housing (1).

[0192] The driving mechanism (6') is not limited to a motor (61'), a driving gear (62'), and a driven gear, and can be applied to any configuration that can slide the display (2").

[0193] Another example of the driving mechanism (6') may further include an apron arranged on the display (2"), an upper plate arranged on the display (2"), and a lifter for raising and lowering the upper plate.

[0194] The apron may include a plurality of supporting members arranged longitudinally in the left-right direction (Y). The apron may support the display (2") from the top or front of the display (2").

[0195] Each of the plurality of supporting members can be attached to a display (2").

[0196] The upper plate can be placed on top of the display (2").

[0197] The lifter can raise or lower the upper plate in the vertical direction (Z) or in an inclined direction close to the vertical direction.

[0198] The lifter may include a driving source such as a motor and a power transmission member such as a gear.

[0199] The above description is merely an example of the technical idea of ​​the present invention, and those skilled in the art will appreciate that various modifications and variations can be made without departing from the essential characteristics of the present invention.

[0200] Accordingly, the embodiments disclosed in the present invention are not intended to limit the technical idea of ​​the present invention but to explain it, and the scope of the technical idea of ​​the present invention is not limited by these embodiments.

[0201] The scope of protection of the present invention should be interpreted by the claims below, and all technical ideas within the scope equivalent thereto should be interpreted as being included in the scope of the rights of the present invention.
