Abstract

An on-vehicle display device mounted on a ceiling including an open and close mechanism, which secures the rearward visibility during the backward driving of the vehicle and also enables the user to continue to enjoy display images. The on-vehicle display device includes a control means which controls the display 1, when the display 1 is open at a best view-angle position, to move in even more widely open direction to a predetermined angle (an displacement-angle position 1b), upon detection of entering a backward driving state of the vehicle. The display 1 is controlled to return to the best view-angle position when the backward driving state of the vehicle is terminated.

Claims

1. An on-vehicle display device which comprises a display open and close mechanism including a controller that electrically performs an open and close control of a ceiling-mounted display in a vehicle, wherein

said display is positioned at a closed position when not in use,

said controller controls the display to move in a direction away from the closed position to a view-angle position when the display is to be used, the view-angle position being at a first angle from the closed position,

said controller controls the display, when it is opened at the view-angle position, to move further in the direction away from the closed position to a predetermined second angle from the closed position, which is greater than the first angle, upon detection of entering a backward driving state of the vehicle.

2. The on-vehicle display device of claim 1, in which said entering said backward driving state of the vehicle is detected by its transmission gear being shifted into a reverse position.

3. The on-vehicle display device of claim 1, in which said controller detects, while said display is positioned at said predetermined second angle, that the backward driving state of the vehicle is terminated, and then controls said display to return to said view-angle position.

4. The on-vehicle display device of claim 3, in which said termination of the backward driving state of the vehicle is detected by its transmission gear being released from the reverse position.

5. The on-vehicle display device of claim 2, in which said controller detects, while said display is positioned at said predetermined second angle, that the backward driving state of the vehicle is terminated, and then controls said display to return to said view-angle position.

6. The on-vehicle display device of claim 1, wherein the display is configured so that, when the display is positioned at the second predetermined angle, the driver'"'"'s rearward field of view is wider than when the display is positioned at the view-angle position.
