Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device capable of easily adjusting an optimum viewing angle of an image.

[0002]

2. Description of the Related Art Generally, when a vehicle-mounted audiovisual device having an opening / closing mechanism is mounted on a car, most of it is attached to a center console part, so that the opening / closing direction does not interfere with the shift lever part of the car. Need to decide.

Further, the liquid crystal monitor has an optimum visual field range due to its characteristics, and if it goes out of this range, the hue changes, so
It is necessary to look in this range.

It should be noted that this optimum viewing angle range also changes when the brightness is changed by a voltage such as the brightness and contrast of the liquid crystal monitor, so that the optimum viewing angle range must be adjusted to the optimum position each time.

In order to meet such a conventional demand, vehicle-mounted liquid crystal televisions as shown in FIGS. 12 to 20 have been proposed. 12 to 14 are the actual exploitation sho 64-1547.
8 and is disclosed in FIG.
Is disclosed in Japanese Utility Model Laid-Open No. 64-15479.

12 to 14 show a vehicle-mounted liquid crystal television having a mechanism in which the outer shape is adjusted to a car stereo size, and when used, the display portion is slid forward from the main body portion, pulled out, and bent upward.

FIG. 12 is a front perspective view of the television main body when in use, FIG. 13 is a front perspective view of the television main body when not in use, and FIG. 14 is a perspective view in a state where the television main body is used by being attached to a center console of a vehicle.

12 to 14, 1 is a display section, 2 is an angle, 3 is an axis, 4 is a main body section, 5
Is an audio device.

When using, the display section 1 is taken out from the main body section 4 for use, and when not in use, the display section 1 is stored in the main body section 4 as shown in FIG. The limited space in the car can be effectively used.

In addition, in the case of FIGS. 15 and 16, the display unit 11 is used by being opened and closed downward from the main body unit 14 by being mounted on the ceiling in the vehicle compartment.

FIG. 15 is a lower perspective view when the liquid crystal television is not attached to the ceiling in the interior of the automobile when not in use, and FIG. 16 is a lower perspective view when it is in use. In both FIGS. , 11 is a display unit, 12 is a liquid crystal surface,
Reference numeral 13 is an axis, and 14 is a main body. When using, the display section 11 is taken out from the main body 14 in a downward direction, and at this time, the axis 13 is centered so that the liquid crystal surface 12 has an optimum viewing angle. The display unit 11 can be rotated to adjust the angle.

Further, FIGS. 17 to 19 are attached to a console section in a private vehicle compartment, have an insertion port for a tape, a disk, etc. in a main body section, and have a display section on the front surface of the main body section. In order to take in and out, the display unit is opened downward from the main body, and FIG. 17 is a perspective view showing a state in which the display unit is used by being attached to the center console of the vehicle.

FIG. 18 is a perspective view showing a state in which the display unit is opened downward from the main body for inserting and removing the tape and the disc. FIG. 19 shows the display unit for inserting and removing the tape and the disc. It is a figure showing interference with a shift lever in the state opened below the main part.

In these FIGS. 17 to 19, 21 is a function switch for switching the operation state,
Reference numeral 22 is a foldable display unit, 23 is an opening / closing switch for performing an opening / closing operation, and 24 is an infrared touch panel switch provided on the front surface of the display unit 23 for performing a screen input operation.

At the rear of the display section 23, there is a main body 28 in which a cassette deck 27 is incorporated. On the front surface of the main body 28, the display section 23 is opened,
Cassette opening 27a for loading and unloading cassette tape
Has a structure.

With such a structure, the display unit 2
3 and the cassette deck 27 are integrated and compact, and the installation space in the center console can be reduced.

FIG. 20 is an external perspective view of a liquid crystal personal computer (hereinafter referred to as a personal computer). This FIG.
In the figure, reference numeral 31 is a rotation axis for moving the display unit 32 back and forth so that the user can adjust the viewing angle to the optimum.

Further, reference numerals 33 and 34 respectively represent a brightness volume and a contrast volume for changing the brightness of the display screen. When the brightness volume 33 and the contrast volume 34 are operated, the optimum viewing angle changes due to the characteristics of the liquid crystal. Therefore, the user manually moves the display unit 32 back and forth to adjust the position of the display unit 32 to the optimum viewing angle.
