Abstract

A display device in the invention comprises an OSP section and OSD switches 10 configured to include a plurality of switches for performing various kinds of setting operations using the OSD section. In OSD switches 10, switches 10a and 10b are disposed on a right side of a front bezel 2 and switches 10c and 10d are disposed on a lower side of the front bezel 2. By that, the OSD switches can be disposed so that a switch operation can be visually performed without an uncomfortable feeling, without increasing the thickness of a front bezel even if the front bezel is narrow.

Claims

1. A display device comprising:

a display screen;

a front bezel surrounding the display screen, the front bezel including first and second sides, the first side being a bottom side and including an end, the second side being different from the bottom side and including an end adjacent to the end of the first side;

an On Screen Display (OSD) section;

a plurality of OSD switches performing various kinds of setting operations using the On Screen Display section, the OSD switches including a first pair of OSD switches for directions of left and right, a second pair of OSD switches for directions of upper and lower, an exit switch corresponding to an exit operation, and a reset switch corresponding to a reset operation, the first pair of OSD switches and the exit switch being disposed on the end of the first side, the second pair of OSD switches and the reset switch being disposed on the end of the second side; and

a control section exchanging operation functions of the OSD switches; and

a determination section configured to detect a rotational state of the display device,

wherein the display device is configured to be rotatable in left and right directions within a plane parallel to the display screen by a rotation mechanism and to indicate a key guide of the OSD switches on the display screen,

wherein when the determination section detects that the display device is rotated 90 degrees, the control section changes operation functions of the first pair of OSD switches to operation functions of the second pair of OSD switches while the control section changes the operation functions of the second pair of OSD switches to the operation functions of the first pair of OSD switches,

and the display device exchanges an indication content of the key guide of the OSD switches so that the indication content corresponds to the operation functions of the OSD switches.

2. The display device according to claim 1, further comprising:

a section displaying a key guide of the OSD switches on the display screen.

3. The display device according to claim 2, further comprising:

a section changing contents of display of the key guide corresponding to operation functions of the OSD switches change according to the type and set value of an OSD setting operation.

4. The display device according to claim 2, wherein when the display device is rotated by the rotation mechanism, the section changes contents of display of the key guide corresponding to operation functions of the OSD switches.

5. The display device according to claim 1, wherein the determination section determines the rotation state of the display device by the rotation mechanism.

6. The display device according to claim 1, wherein the operation functions of the OSD switches change to visually correspond to the rotation state of the display device, and

wherein the indication content of the key guide, displayed along each of the two sides of the display screen corresponding to the plurality of OSD switches on the front bezel, is changed according to the change of the operation functions of the plurality of OSD switches.

7. The display device according to claim 1, wherein the display device is configured to change a color of a key guide of one of the OSD switches in a case where the one of the OSD switches cannot be operated.

8. The display device according to claim 1, wherein when the determination section detects that the display device is rotated 90 degrees, the control section changes an operation function of the reset switch to an operation function of the exit switch while the control section changes the operation function of the exit switch to the operation function of the reset switch.

9. An arrangement method of on screen display (OSD) switches in a display device, the display device comprising:

a display screen;

a front bezel surrounding the display screen, the front bezel including first and second sides, the first side being a bottom side and having an end, the second side being different from the bottom side and having an end adjacent to the end of the first side;

an OSD section;

a plurality of OSD switches performing various kinds of setting operations using the OSD section,

the OSD switches including a first pair of OSD switches for directions of left and right, a second pair of OSD switches for directions of upper and lower, an exit switch corresponding to an exit operation, and a reset switch corresponding to a reset operation;

a control section exchanging operation functions of the OSD switches; and

a determination section configured to detect a rotational state of the display device,

the arrangement method comprising;

disposing the first pair of the OSD switches and the exit switch on the end of the first side;

disposing the second pair of the OSD switches and the reset switch on the end of the second side; and

exchanging operation functions of the OSD switches,

wherein the display device is configured to be rotatable in left and right directions within a plane parallel to the display screen by a rotation mechanism and to indicate a key guide of the OSD switches on the display screen,

wherein when the determination section detects that the display device is rotated 90 degrees, the control section changes operation functions of the first pair of OSD switches to operation functions of the second pair of OSD switches while the control section changes the operation functions of the second pair of OSD switches to the operation functions of the first pair of OSD switches

and the display device exchanges an indication content of the key guide of the OSD switches so that the indication content corresponds to the operation functions of the OSD switches.

10. The arrangement method according to claim 9, wherein the plurality of OSD switches are disposed on a front bezel surrounding the display device,

wherein the operation functions of the OSD switches change to visually correspond to the rotation state of the display device, and

wherein the indication content of the key guide, displayed along each of the two sides of the display screen corresponding to the plurality of OSD switches on the front bezel, is changed according to the change of the operation functions of the plurality of OSD switches.

11. The arrangement method according to claim 9, wherein the display device is configured to change a color of a key guide of one of the OSD switches in a case where the one of the OSD switches cannot be operated.

12. The arrangement method according to claim 9, wherein when the determination section detects that the display device is rotated 90 degrees, the control section changes an operation function of the reset switch to an operation function of the exit switch while the control section changes the operation function of the exit switch to the operation function of the reset switch.
