Description

Configuration method of display device and OSD switch

technical field

The invention relates to a display device with an OSD (On Screen Display) function and an OSD switch for performing OSD setting operations, and a method for configuring the OSD switch.

Background technique

FIG. 13 is a diagram showing a configuration example of a conventional display device. 13A, 13B, and 13C respectively show a display device having an OSD (On Screen Display) function. Each display device has OSD switches 13a, 13b, and 13c arranged on a front bezel (frame) for performing various settings through an OSD function. Various OSD settings of the display device are performed through an on-screen menu (also called an on-screen menu) using the OSD switches 13a, 13b, 13c.

Among them, OSD is a function of a display device that can display an on-screen menu in a part of the display screen and set various setting values of the display device, etc., and can confirm and adjust the brightness, contrast (CONTRAST) and screen size, etc. In addition, in this specification, an "OSD switch" is also simply called a "switch".

In FIG. 13, in the conventional display device, as shown by the switch 13a, four keys (switches) are arranged in the cross direction, and the setting of the display device is changed by moving the cursor in four directions on the screen menu. Thus, the user can perform operations intuitively.

Recently, space has been saved by downsizing the front frame (bezel) of the display device. However, since the front frame is narrowed and the bezel is narrow, there is no space for arranging the OSD switches in the cross direction, so that a cross arrangement cannot be adopted. Therefore, although it is an operation in the direction of the cross, it can only be arranged in a row in the horizontal direction like the switch 13b, or only the selection mode of the screen menu that is not operated by the cross can be used.

Alternatively, as shown in the switch 13c, there may be a stick type operation button. This saves space and realizes the cross operation, but as shown in FIG. 13D , since the switch 13c thickens in the thickness direction, the appearance is impaired.

As a conventional OSD input method, there is a method described in Patent Document 1, for example. The purpose of this prior art OSD input method is to provide an OSD input unit with few misoperations, excellent operability, and high reliability. Therefore, an operation menu screen for adjusting brightness, contrast, etc. of the display screen is displayed multiple times on the display screen of the display device. A non-contact switch corresponding to the operation menu is provided on the front frame of the display device, such as the bottom surface, near the operation menu screen of the display screen. By operating the non-contact switch, the control of the display device corresponding to the operation of the non-contact switch input is performed.

However, this prior art OSD input method does not solve the configuration problem of the OSD switch caused by the narrowing of the front frame.

Patent Document 1: Japanese Patent Laid-Open No. 2003-158692

Contents of the invention

As mentioned above, in the conventional display device shown in Fig. 13A ~ Fig. 13D, there are the following problems, if the switches 13a arranged in a cross are used, the frame becomes wider; Switches cannot be arranged in a cross direction. In addition, if the rod-shaped switch 13c is used, the thickness direction of the display device will become thicker and the like.

The present invention is made to solve the above-mentioned problems, and its purpose is to provide a display device and an OSD switch arrangement method, without increasing the thickness of the narrow front frame, the OSD switch can be arranged so that the switch operation does not feel uncomfortable visually , and can improve the operability of the OSD switch.

A display device of the present invention has an OSD (On Screen Display) function and a plurality of OSD switches for performing various setting operations using the OSD function, and the OSD switches are separately arranged on the front frame surrounding the display screen. two sides.

Therefore, even if the front frame is narrow and there is no space for arranging the switches in a cross direction on one side, by arranging the switches on both sides at the same time, the switches can be arranged up, down, left, and right, and the switches can be operated with a feeling of being arranged in a cross .

In addition, in the display device of the present invention, the OSD switches may also be arranged on two adjacent sides of the front frame.

Therefore, even if the front frame is narrow and there is no space for arranging the switches in a cross direction on one side, by arranging the switches on both sides at the same time, the switches can be arranged up, down, left, and right, and the switches can be operated with a feeling of being arranged in a cross . Furthermore, since the operation of the on-screen menu can visually correspond to the OSD switch, the on-screen menu can be intuitively operated without discomfort, thereby improving operability.

In addition, in the display device of the present invention, the OSD switch may be constituted by a switch for the cross direction in the up, down, left and right directions, or may be constituted by the switch for the cross direction and other desired switches other than the cross direction.

In this way, not only can the switches be arranged up, down, left, and right, and can be operated in a cross-arranged sense, but also the functions operable by the OSD switches can be expanded. For example, other operations (for example, RESET (reset) operations, etc.) can be performed only by moving the cursor in the up, down, left, and right directions on the screen menu, thereby improving operability.

In addition, the display device of the present invention is preferably configured to be rotatable to the left and right in a plane parallel to the display screen by a rotation mechanism.

Thus, in a rotatable display device, even if the front frame is narrow and there is no space for arranging the switches in the cross direction on one side, the switches can be arranged up, down, left, and right by arranging the switches on both sides at the same time. .

In addition, the display device of the present invention may include means for replacing the operation functions of the OSD switches arranged on each side of the front frame when the display device is rotated by the rotation mechanism.

Accordingly, even when the display device is rotated, the setting operation can be performed without uncomfortable feeling through visually corresponding switch operations, thereby improving operability.

In addition, in the display device of the present invention, the OSD switch may also include switches for the cross direction in the up, down, left, and right directions, or include switches for the cross direction in the up, down, left, and right directions and other function switches other than for the cross direction, Furthermore, means for replacing the operation functions of the respective switches for the cross direction and/or function switches other than for the cross direction when the display device is rotated by the rotation mechanism is included.

Thus, even when the display device is rotated, visually corresponding switching operations can be performed on the switches for the cross direction and/or function switches other than the cross direction, and the setting operation can be performed without discomfort. Improve operability.

In addition, in the display device of the present invention, it is preferable to include means for displaying a key guide of the OSD switch on the display screen.

Therefore, in the case where the front frame is narrow and it is not easy to set engraving or silk screen on the OSD switch, by marking the function of the switch in the screen of the display device near each switch instead of the engraving or silk screen, even if no engraving or silk screen is provided. Silk screen printing can also clearly indicate the function of each switch, thereby improving operability.

In addition, the display device of the present invention may include means for making the display content of the key guide coincide with that of the OSD switch when the operation function of the OSD switch changes corresponding to the type and setting value of the OSD setting operation. The operating functions of the corresponding changes.

Thus, in the process of performing various setting operations through the OSD, when the operating function of the OSD switch changes corresponding to the type and setting value of the setting, the identification content of the key guide can be changed correspondingly, thereby enabling Clearly show the effect of the switch operation. In this way, operability can be improved by changing the display of the key guide according to the status of the setting operation.

In addition, the display device of the present invention may include means for determining a rotation state of the display device rotated by the rotation mechanism.

In this way, it is possible to automatically determine whether the display device is rotated without manual operation, so that the operating function of the OSD switch can be automatically switched.

In addition, an OSD switch configuration method of the present invention is characterized in that, in a display device having an OSD function and a plurality of OSD switches for performing various setting operations using the OSD function, the OSD switch Separately arranged on both sides of the front frame surrounding the display screen.

In this way, even if the front frame is narrow and there is no space for arranging the switches in the cross direction on one side, by arranging the switches on both sides at the same time, the switches can be arranged up, down, left, and right, and the operation can be performed with a sense of a cross arrangement. .

In the display device of the present invention, the OSD switches are separately arranged on both sides of the front frame surrounding the display screen, so even if the front frame is narrow and there is no space for arranging the switches in the cross direction on one side, the OSD switches can be By arranging the switches on both sides, the switches can also be arranged up, down, left, and right, and operated in a cross-like arrangement.

[first embodiment]

1 is a diagram showing a first embodiment of a display device according to the present invention, showing an example of an arrangement of OSD (On Screen Display: On Screen Display) switches 10 in a display device 1. In FIG. 1 , OSD switches 10 arranged in an L-shape are provided on a front frame (frame) 2 around a display screen 3 of a display device 1 . The OSD switch 10 shown in Fig. 1 is distributed as follows, switch 10a is an upward direction key (upward direction switch), switch 10b is a downward direction key (downward direction switch), switch 10c is a right direction key (right direction switch), and switch 10d It is the left direction key (left direction switch). On the right side of the front frame 2, the switch 10a is arranged on the upper side of the switch 10b, and on the lower side, the switch 10d is arranged on the left side of the switch 10c. In addition, in this specification, an "OSD switch" may be simply called a "switch".

FIG. 2 is a block diagram showing an example of the circuit configuration of the display device according to the first embodiment of the present invention, and shows a portion directly related to the present invention. Referring to FIG. 2 , the display device 1 is composed of a video processing unit 101 , a video mixing unit 102 , a video display unit 103 , an operation signal processing unit 104 , and an OSD control unit 105 .

In FIG. 2 , an operation signal processing unit 104 detects a switch operation signal a obtained by pressing one of the OSD switches 10 , and outputs a control signal b corresponding to the switch operation to the OSD control unit 105 . The OSD control unit 105 generates an OSD video signal c corresponding to the pressed switch, and outputs it to the video mixing unit 102 . The video processing unit 101 performs image processing on the input video signal d to generate a processed video signal e, and outputs it to the video mixing unit 102 . The video mixing unit 102 mixes (MIXING) the processed video signal e processed by the video processing unit 101 and the OSD video signal c, generates a mixed video signal f, and outputs it to the video display unit 103 . The video display unit 103 receives the mixed video signal f and displays the video.

For example, as shown in the picture (A) of Figure 3, when the on-screen menu is displayed on the OSD picture 4, if the cursor is to be moved from C to turn on TRAST (contrast) to AUTOC to turn on TRAST (automatic contrast) in the menu, Then press the switch 10b shown in FIG. 1 . The operation signal processing unit 104 detects the switch operation signal a indicating that the switch 10b is pressed, outputs a control signal b, and controls the OSD control unit 105 . The OSD video signal c which is a signal of the on-screen menu generated by the OSD control unit 105 is sent to the video mixing unit 102 .

The processed video signal e obtained by processing the input video signal d by the video processing unit 101 and the OSD video signal c output by the OSD control unit 105 are synthesized in the video mixing unit 102 and displayed on the screen by the video display unit 103 . As a result, as shown in the screen (E) of FIG. 3 , it is possible to display that the cursor is moved to the next step.

If wish to reduce the percentage (%) value that C connects TRAST (contrast) bar 5 from the position of picture (A) of Fig. 3, then by pressing the left direction shown in Fig. 1 with switch 10d, the display of OSD becomes as shown in Fig. Frame (C) of 3 shows that the percentage (%) of C ON TRAST bar 5 is reduced from 70% to 50%.

In addition, if you want to increase the percentage (%) value of C connecting the TRAST bar 5 from the position of the screen (A) in Fig. 3, by pressing the right direction switch 10c shown in Fig. 1, the display of the OSD becomes as shown in Fig. 3 The percentage (%) of C turning on TRAST bar 5 shown in panel (D) increases from 70% to 100%.

In addition, if it is desired to move the cursor to the upper side from the position of the screen (A) in FIG. 3, by pressing the upward direction switch 10a shown in FIG. 1, the display of the OSD becomes as shown in the screen (B) of FIG. The cursor moves to the upper side.

Thus, according to the first embodiment of the present invention, even if there is no space for arranging the switches in the cross direction on one side of the narrow front frame (frame), by arranging the switches on both sides at the same time, the switches can be arranged up and down. about. Thereby, it is possible to visually associate the operation of the on-screen menu with the OSD switch. Therefore, the on-screen menu can be intuitively operated without uncomfortable feeling, and operability can be improved.

In addition, in the example shown in Fig. 1, have shown the example that the OSD switch 10 function is identified by the arrows of up, down, left, and right, but the signs and the use of words such as UP/DOWN/LEFT/RIGHT (up/down/left/right) The identification of other symbols representing the same meaning can also achieve the same effect.

[Second Embodiment]

Next, a second embodiment of the present invention will be described. Fig. 4 is a diagram showing a second embodiment of the display device of the present invention. The example shown in FIG. 4 shows a state where the display device 1 shown in FIG. 1 is rotated 90 degrees to the right. In addition, FIG. 5 is a block diagram showing an example of a circuit configuration of a display device according to the second embodiment.

The switches 10a, 10b, 10c, and 10d shown in FIG. 4 are physically the same switches as the switches 10a, 10b, 10c, and 10d shown in FIG. 1 .

Referring to FIG. 5 , the operation signal conversion unit 110 converts the switch operation signal a in accordance with the rotation of the display device 1 to generate a converted switch operation signal a1. The other blocks are the same as those in Fig. 2, so descriptions are omitted.

6A is a flowchart showing the processing flow of the display device 1 , and FIG. 6B shows a key conversion processing table used when switching the switch operation signal a in accordance with the rotation of the display device 1 .

Next, the operation of the above configuration example will be described. If it is desired to move the cursor to the lower side in the screen menu shown in the screen (A) of FIG. In the display state), it is necessary to press the switch 10b in FIG. 4 . Also, to increase the percentage (%) value that C turns on the TRAST bar 5, it is necessary to press the switch 10c. Also, if the percentage (%) value of the bar 5 is to be decreased, it is necessary to press the switch 10d, which are visually different from the corresponding switches, thereby causing discomfort. Therefore, when the mounting direction of the switch 10 is rotated by 90 degrees, the operation of each switch is changed.

The switch 10c originally corresponds to the switch in the right direction, so if it is not changed, the action in the right direction is performed when the switch 10c is pressed, that is, C turns on the TRAST bar 5 to increase the action. In contrast, the operation signal conversion unit 110 converts the motion in the right direction into the motion in the downward direction. After the converted switch operation signal a1 is output to the operation signal processing unit 104, the cursor moves down as described in the first embodiment, and the state shown in the screen (E) of FIG. 3 is reached.

Similarly, when the switch 10a is pressed, a switch signal for the right direction is output as the converted switch operation signal a1, and the state shown in the screen (D) of FIG. 3 is reached. In addition, when the switch 10b is pressed, the signal of the left direction switch is output as the converted switch operation signal a1, and the state shown in the screen (C) of FIG. 3 is reached. When the switch 10d is pressed, the signal of the upward direction switch is output as the converted switch operation signal a1, and it becomes the state shown in the screen (B) of FIG. operation.

Next, the flow of operations will be described with reference to the flowchart shown in FIG. 6A . First, it is detected that the switch 10 shown in FIG. 4 is pressed (step S1). Then, it is checked whether the switch 10 is currently in a rotated state (the state in which the switch 10 is rotated 90 degrees to the right as compared with FIG. 1 ) (step S2).

In step S2, if it is judged that it has been rotated, key switching processing is performed (step S3). As for the conversion processing, as shown in the conversion processing table of FIG. 6B, when the switch 10a is pressed, an upward motion is performed if the switch 10a is not rotated, and a rightward motion is performed if the switch 10a is already rotated. Similarly, when the switch 10b is pressed, the downward motion is converted to the leftward motion, when the switch 10c is pressed, the rightward motion is converted to the downward motion, and when the switch 10d is pressed, the leftward motion is converted to the upward motion.

In the operation signal processing shown in FIG. 4 , processing corresponding to the key operation is performed, OSD control corresponding to the key operation is performed (step S5 ), and OSD display is performed (step S6 ).

In this way, according to the second embodiment of the present invention, in the display device in which the switch is arranged in an L-shape, when the display device is rotated, the function of the switch is replaced to perform a visually corresponding action, thereby achieving the same as the first embodiment. Realize movements without discomfort.

In this way, even if the switches are arranged in an L-shape, operability similar to that of the conventional cross arrangement can be obtained.

[Third Embodiment]

Next, a third embodiment of the present invention will be described. When an OSD switch is operated, a function assignment corresponding to each switch is performed. In order to clarify the functions of the switches, engravings or silk prints are generally provided on or near the switches. However, since the front frame has a narrow frame, it may not be possible to easily provide engraving or serigraphy as described above. In this case, the function of each switch can be clearly indicated without engraving or silkscreen by indicating the switch function on the screen of the display device near each switch by OSD or the like instead of engraving or silkscreen. This example will be described.

7 is a diagram showing a third embodiment of the display device of the present invention, showing an example of the OSD switch 10 of the display device 1 and the switch function identified on the OSD screen. As shown in Figure 7, on the display screen 3, the switch 10a is shown as an upward direction switch, the switch 10b is a downward direction switch, the switch 10c is a right direction switch, and the switch 10d is a left direction switch through the screen display, thereby clearly indicating that the key is assigned to each key. of each function.

Fig. 8 is a diagram showing an example of another mark displayed on the screen. In the example shown in FIG. 8, the switch 10c is identified on the screen as a + arrow key, and the switch 10d is identified as a - arrow key.

Next, the operation in the above configuration example will be described. When the cursor is on the uppermost side as shown in the screen (F) of FIG. 3 , by pressing the right direction switch 10c and the left direction switch 10d shown in FIG. 7 , the cursor moves left and right on the horizontally long menu 6 ( not shown). When the cursor is at the position shown in the screen (A) of FIG. 3 , the operation of increasing and decreasing the bar 5 is performed.

At this time, at the position of the cursor shown in the screen (F) of FIG. 3 , as shown in FIG. The screen (F) of 3 clearly shows that the operation of the switches 10c and 10d is the left and right movement of the cursor.

In addition, at the position of the cursor shown in the screen (A) of FIG. 3, as shown in FIG. 8, a key guide "-" is displayed on the switch 10d, and a key guide "+" is displayed on the switch 10d, clearly indicating the operation of the switches 10c and 10d. Turn on the increase and decrease of TRAST bar 5 for C. This makes it easier for the user to visually confirm the operation of the screen.

In this way, in the third embodiment of the present invention, the indication content of the key guide is changed according to the position of the cursor of the on-screen menu, so that the function of the key operation can be clearly indicated to the user.

In addition, in the state shown in the screen (D) of FIG. 3 , C turns ON the TRAST bar 5 to display MAX (maximum 100%). Therefore, it is not possible to turn C on TRAST bar 5 to operate in the increasing direction. Therefore, as shown in FIG. 9 , in order to clearly indicate that the TRAST bar 5 cannot be turned on by increasing C, the rightward key guide "+" on the upper side of the switch 10c is eliminated. Thereby, the user can recognize at a glance which switch is valid, so that the user does not press the right direction switch 10c by mistake, and it is easy to visually confirm the operation of the screen. In addition, instead of erasing the key guide "+", the color may be changed to gray or the like to clearly indicate that it cannot be operated (not shown).

[Fourth embodiment]

Next, a fourth embodiment of the present invention will be described.

Fig. 10 is a diagram showing a fourth embodiment of the display device of the present invention. The example shown in FIG. 10 is an example in which the display device of the third embodiment shown in FIG. 7 is rotated 90 degrees to the right. In addition, in the fourth embodiment, the flowchart shown in FIG. 6A shows the flow of operations, and FIG. 6C shows a key conversion processing table.

The switches 10a, 10b, 10c, 10d, 10e, and 10f shown in FIG. 10 are physically identical to the switches 10a, 10b, 10c, 10d, 10e, and 10f shown in FIG. As an EXIT (escape) key, switch 10f is an example configured as a RESET (reset) key. In this manner, it is also possible to replace the assignment of keys when the display device 1 is rotated for switches other than the up, down, left, and right direction switches.

The operation of the configuration example shown in FIG. 10 will be described. For example, the switch 10e shown in Figure 7 is a reset switch, and the switch 10f is a switch of EXIT, but if the original function remains unchanged after being rotated 90 degrees, then the reset switch 10e on the upper side of the switch in the up and down direction moves to the left and right. Next to the direction switches 10a, 10b. In addition, the EXIT switch 10f located next to the left and right direction switches is moved to the upper side of the up and down direction switches 10c and 10d.

In this case, the positional relationship of the switch is different from that before the rotation, which causes discomfort. Therefore, when the switch 10e shown in FIG. 10 is pressed, the switch operation signal a is converted into an EXIT signal by the operation signal conversion unit 110 shown in FIG. 5 . In addition, when the switch 10 f shown in FIG. 10 is pressed, the switch operation signal a is converted into a RESET signal by the operation signal conversion unit 110 . In this way, by replacing the RESET and EXIT signals of the switch 10e and the switch 10f, it is possible to perform switching operations without discomfort.

In addition, in the fourth embodiment, in the flowchart shown in FIG. 6A , the key conversion processing in step S3 is performed using the key conversion processing table shown in FIG. 6C . When the switch 10e is pressed, if the display device 1 has not been rotated 90 degrees to the right, the RESET operation is performed, but if the display device 1 has been rotated, it is switched to the EXIT operation. In addition, when the switch 10f is pressed, if the display device 1 is not rotated, the EXIT operation is performed, but if the display device 1 is already rotated, the display device 1 is switched to the RESET operation. The processing of other switches is the same as that of the second embodiment, and description thereof is omitted.

As shown in Figure 10, when the switch is rotated 90 degrees to the right, if RESET is marked next to the switch 10f and EXIT is marked next to the switch 10e on the screen, even if the switch action is replaced, no error will occur. to operate.

In addition, when the switch function is replaced with a display device having an engraved or silk-screened mark written on the switch or the front frame, the engraved or silk-screened mark becomes a wrong mark. In this regard, we consciously do not write engraved or silk-screened marks on the switch or the front frame, but use the key guide to guide, so that the switch can be replaced without discomfort. In addition, since there is no engraving or silk printing on the switch or the front frame, it is also neat in appearance.

[Fifth Embodiment]

Next, a fifth embodiment of the present invention will be described.

Regarding the above-mentioned rotation of the OSD switch, conventionally, a rotating OSD menu (a menu that replaces the function of the OSD switch) is used, or whether to use the normal OSD menu (a menu without the function of changing the OSD switch) is set by the user through an on-screen menu, etc. . In this embodiment, however, whether to rotate is automatically recognized.

11A to 11G are diagrams showing a fifth embodiment of the display device of the present invention, showing the appearance of the display device. In addition, FIG. 12 is a diagram showing an example of a circuit configuration of a display device in the fifth embodiment.

In FIG. 11 , FIG. 11A is a side view of the display device with a stand having a stand 7 , and FIG. 11B shows a rear view of the display device with a stand. FIG. 11C shows a side view of the display device after the stand 7 is removed. FIG. 11D shows a rear view of the standless display device after the stand 7 is removed.

11E and 11F are enlarged views of the rotation judging switch 11 disposed on the circled portion in FIGS. 11C and 11D .

In FIG. 12 , a rotation judging switch 11 for judging the rotation of the display device 1 is connected to the operation signal conversion unit 110 . The other parts are the same as the circuit block diagram shown in Fig. 5, so description is omitted.

The operation in the above configuration example will be described. Assume that the holder 7 approaches the rotation determination switch 11 in the state shown on the left side of FIG. 11E and FIG. 11F from the direction of the black arrow h. At this time, the holder 7 presses the rotation determination switch 11 from the direction of the black arrow h, and the state on the right side of FIG. 11E and FIG. 11F is established. When the holder 7 comes to the back of the rotation determination switch 11, the rotation determination switch 11 is always pressed. That is to say, when there is no rotation, the rotation judging switch 11 is pushed and maintained in an ON state. When it is rotated, as shown in FIG. Pressed to maintain the OFF state.

Referring to FIG. 12 , by rotating the judging switch 11 , a signal indicating whether the turning judging switch 11 is on or off, that is, a rotation judging switch signal g, is sent to the operation signal conversion unit 110 . Accordingly, OSD menu actions and key guide display are handled as either the non-rotated state or the rotated state. That is, in step S2 of the flowchart of FIG. 6A, the rotation judgment is automatically performed, and the conversion processing of the key action is performed through the conversion processing table shown in FIG. 6B or 6C.

In this way, according to the fifth embodiment of the present invention, it is possible to automatically determine whether or not the display device 1 is rotated, so that the OSD function and the OSD switch can be automatically replaced.

In addition, in the example shown in FIG. 11 , the rotation state of the stand 7 and the display device 1 is identified by the ON/OFF state of the rotation judgment switch 11, but it is also possible to provide contacts on the back of both the stand 7 and the display device 1. Terminals are identified based on contact/non-contact of the contact terminals. In addition, other sensors such as a magnetic sensor and an infrared sensor may also be used to detect the rotation state of the stand 7 and the display device 1 .

In addition, in the example shown in FIG. 11 , the rotation state can be recognized when the stand is used, but the rotation state is always erroneously recognized when the stand is not used because the switch remains off. In this regard, for example, if a tilt sensor, a gravity sensor, etc. are provided to recognize whether the display device itself is tilted, whether the display device 1 is rotated can be recognized regardless of whether the stand 7 is used or not.

As described above, according to the present invention, even if the front frame (frame) is narrow and there is no space for arranging the switches vertically and horizontally on one side of the front frame, by arranging the switches on both sides, it is possible to visually avoid discomfort. By arranging switches corresponding to the up, down, left, and right directions, operability can be improved. In addition, even if the display device is rotated, the on-screen menu can be operated by switching the switch operation in the up-down direction and the left-right direction. In addition, in the example of the embodiment of the present invention, an example in which the OSD switch is arranged on the lower right without being rotated is given, but the same applies to the case where the OSD switch is arranged on the upper right, upper left, and lower left.

In addition, when the front frame is made into a narrow bezel, it is difficult to mark marks or characters such as engraving or serigraphy on the front frame in terms of space, but in this case, by displaying the key guide on the display screen, even if there is no engraving Or serigraphy, etc., can also clearly show the switch function (key function) to the user.

In addition, when the key guide is displayed, even if the function assigned to each key (switch) is changed by rotating the display device, the change of the function assignment can be clearly indicated by changing the display content of the key guide, so that the user can easily perform key operations. .

In addition, since it is automatically determined whether the display device is rotated, menu operations can be performed without manually switching between the OSD function and the OSD switch function.

In addition, in the embodiment of the present invention, when the display device 1 is rotated, an example of rotating 90 degrees to the right is given. Thought coping.

Embodiments of the present invention have been described above, but the display device of the present invention is not limited to the illustrated examples described above, and various changes can be made without departing from the gist of the present invention.

Industrial availability

The present invention can dispose the OSD switch without increasing the thickness of the narrow front frame so that the switch operation has no visual discomfort, so it is suitable for display devices and OSD switch disposition methods and the like.
