JP 2010-191649 A

  As described above, in schools, efforts are being made to realize IT in the educational environment, but it is the actual situation that it is not possible to say that IT is advanced in the learning environment for children in the home. For example, at home, a notebook PC (notebook personal computer) or tablet terminal is simply used for learning, but the terminal cannot be used efficiently at a learning desk.

  For example, when a display device is installed at a learning desk, in order to perform learning while viewing an image on the display device, the user needs to input an operation to the displayed image and appropriately advance learning. In this case, it is conceivable to perform learning by performing a touch operation on the user interface displayed on the display device. Usually, however, the learning desk has a display device installed at the end opposite to the position where the user is sitting on the learning desk. In some cases, the hand may not reach the display surface of the display device, and there is a problem that it is difficult to operate even if the hand reaches.

  Therefore, a configuration that can easily and intuitively operate the user interface displayed on the display screen of the display device is required. For this purpose, by providing a touch panel on the desk and associating the coordinate position of the display screen of the display device with the coordinate position of the touch panel, the operation by the touch panel on the desk becomes possible. In this case, a touch operation can be performed by mounting the same monitor as the display screen on a desk, providing a capacitive touch panel on the monitor, and displaying the same screen as the display screen of the display device on the monitor. However, in this case, another monitor must be provided on the desk, which complicates the configuration and increases costs.

  In order to solve such a problem, it is conceivable that only a touch panel is provided on a desk, and a screen operation template is installed under the touch panel. Selection elements such as a key display and various buttons are printed in advance on the template, and a user interface is displayed on the display device according to the template. When the user touches a specific position on the touch panel, the user interface position corresponding to the coordinates is controlled as being touched, so that an intuitive operation using the touch panel on the desk can be performed.

In addition to touch panels, systems capable of touch input operations using a digital pen are known. In this digital pen, dots with different patterns are arranged on the paper according to the location, and a camera built in the digital pen photographs the dot pattern. The captured dot pattern is processed by a processor built in the digital pen, and the coordinate position is calculated. This coordinate position is sent to the display device. A template for screen operation is printed in advance on paper on which a dot pattern for inputting a digital pen is printed, and a user interface is displayed on the display device in accordance with the template. A transparent plate such as glass or acrylic for protecting the paper is disposed on the surface of the paper on which the dot pattern is printed. Alternatively, the dot pattern may be printed on the transparent plate.
Then, according to the touch position of the digital pen, control is performed as if the position of the user interface corresponding to the coordinates calculated from the dot pattern is touched. Thereby, intuitive operation using the dot pattern on a desk and a digital pen can be performed.

  As described above, when a touch panel or a digital pen operation plate is placed on a desk, the user can perform an intuitive operation at hand, but the user sat in front of a learning desk with a display device. In this case, the display screen of the display device is reflected on the touch panel provided on the desk immediately in front of the user or the transparent plate for operating the digital pen and reflected, the visibility of the template is deteriorated, and the operability is deteriorated. The problem arises.

Thus, when a display device is installed at a predetermined position, functions as shown in the following embodiments are realized.

(Embodiment 1)
1A and 1B are diagrams schematically illustrating an external configuration example of a desk with a display device according to an embodiment of the present invention.
The display device-equipped desk 1 is configured by combining a desk 10 and a thin display device 20. The display device 20 is a thin display device using an FPD (Flat Panel Display), and is configured as a liquid crystal display device using a liquid crystal display panel, for example.
The display device 20 is installed on the surface of the top plate 11 at one end portion of the top plate 11 of the desk 10 with the display screen 21 of the display device 20 facing the opposite end portion of the top plate 11. In this example, the display device 20 is installed so as to be perpendicular to the top plate 11, but is not limited to this configuration, and the display device 20 is inclined with respect to the top plate 11. It may be arranged. Further, a tilt mechanism capable of changing the angle between the display device 20 and the top plate 11 may be provided so that the angle between the top plate 11 and the display device 20 can be set as appropriate. Hereinafter, a configuration in which the display device 20 is provided perpendicular to the top plate 11 will be described as an example.
The user can usually sit on the front face of the display device-equipped desk 1 and perform work such as learning using the top plate 11 of the desk 10 while viewing the display screen 21 of the display device 20.

  An operation unit 30 for user operation is provided on the surface of the top plate 11 of the desk with display device 1. The operation unit 30 includes an operation template and a touch panel provided on the surface thereof. Alternatively, an operation template is printed on paper on which a dot pattern for operation with a digital pen is printed, and a protective transparent plate such as glass or an acrylic plate is installed on the surface. The dot pattern may be printed on a protective transparent plate. 1A and 1B show an example in which the operation unit 30 is installed at different positions. FIG. 1A shows an example in which the operation unit 30 is installed at a substantially central portion of the top plate 11, and FIG. The example which installed the operation part 30 in the position of the right end of the board 11 is shown.

FIG. 2 schematically shows an example of the configuration of the template. For example, a keyboard and buttons are preprinted on the template. A user interface corresponding to the template is displayed on the display screen 21 of the display device 20. For example, a touch panel is provided on the template, and the coordinate position when the touch panel is touched corresponds to the coordinate position of the user interface, and the display device 20 can perform processing according to the coordinate position touched on the touch panel. .
The operation with the digital pen is the same, and the camera built in the digital pen captures the dot pattern, and the processor including the digital pen processes the captured dot pattern to calculate the coordinate position. This coordinate position can be sent to the display device 20, and processing corresponding to the coordinate position can be performed by the display device.

The user usually sits in front of the desk 1 with the display device, visually recognizes the display screen 21, and performs a task such as learning using the top plate 11. An operation input to the display screen of the display screen 21 can be performed while operating the operation unit 30.
At this time, the display screen 21 displayed on the display device 20 is reflected and reflected on the operation unit 30 to deteriorate the visibility of the template and the operability.

FIG. 3 is a diagram schematically illustrating a relationship between the display device and the top board according to the first embodiment of the present invention, and is a diagram illustrating an example of a relationship between the display state of the user interface and the operation unit.
A user interface 22 for user operation can be appropriately displayed on the display screen 21 of the display device 20. The user interface 22 for user operation is, for example, a software keyboard or a button for a user to select and operate. When the user interface 22 for these specific user operations is displayed, the user can operate a user interface such as a software keyboard by performing a touch operation using the operation unit 30.

  In the embodiment according to the present invention, when the user interface 22 for a specific user operation is displayed on the display screen 21, when the user interface 22 is visually recognized by the user, at least part of the luminance of the display screen 21. Reduce the darkness. Thereby, the user can perform an operation process on the operation unit 30 without deteriorating the visibility of the template due to the display screen 21 reflected on the operation unit 30.

  In the present embodiment, the normal line of the display screen passing through the center position of the display screen 21 and the normal line of the top plate 11 at the end position of the top plate 11 opposite to the end where the display device 20 is installed intersect. It is assumed that the user's viewpoint p is set at the position. That is, the position of the viewpoint p is a height position that is ½ of the height H of the display screen and a position that is 1/2 (W / 2) of the width W of the display screen, and the position in the depth direction. Is the end position of the top plate 11 opposite to the display screen 21. The distance from the viewpoint p to the display screen 21 is the same as the distance L from the display screen 21 to the end of the top plate 11. In this case, when viewed from the front of the desk 1 with the display device, the shape of the display screen 21 reflected on the top plate 11 and reflected is a trapezoidal shape. Here, a region where the reflection of the display screen 21 does not occur at the viewpoint p is a region indicated by a hatched region S.

In the present embodiment, the operation unit 30 is set at a substantially central position in the width direction of the top plate 11. At this time, when the viewpoint p is at the position shown in FIG. 3, the display screen 21 is reflected by the operation unit 30 and can be viewed at the position of the viewpoint p.
When the user does not operate the operation unit 30, the user does not visually recognize the operation unit 30 itself, and thus it can be said that the display screen 21 is not reflected in the operation unit 30. Here, it is assumed that the user interface 22 operable by the operation unit 30 is displayed on the display screen 21. The user interface 22 is, for example, a software keyboard. In this case, the user performs a touch operation on the operation unit 30 and visually performs an operation input on the software keyboard while visually recognizing the keyboard template of the operation unit 30. At this time, if the display screen 21 is reflected on the operation unit 30 and reflected, the user has difficulty in visually recognizing the template and hinders operability.

Therefore, in the present embodiment, when the user interface 22 to be operated using the operation unit 30 is displayed on the display screen 21, the display device 20 reduces the luminance of at least a part of the area of the display screen 21. Let it darken.
In this example, the brightness of the entire area of the display screen 21 when the user interface 22 is displayed can be lowered and darkened. Alternatively, a screen area in which the display screen reflected on the operation unit 30 can be visually recognized at the position of the viewpoint p may be calculated, and the brightness of the screen area may be reduced and darkened. Further, a certain margin may be given around the screen area calculated here, and the brightness of the screen may be lowered and darkened in the area where the margin is given. In any case, when the user interface 22 to be operated using the operation unit 30 is displayed, the operation unit 30 is displayed in order to reduce the reflection by the operation unit 30 visible at the position of the viewpoint p. The brightness of at least a part of the display screen 21 including the screen area that can be reflected and viewed from the viewpoint p is reduced.

  The luminance of the display screen 21 is reduced by reducing the luminance of the backlight that illuminates the liquid crystal panel constituting the display device 20 or by processing the video signal to be displayed on the liquid crystal panel to reduce the luminance of the video signal. Can be executed. In addition, a reduction in luminance of the backlight and a reduction in luminance due to video signal processing may be used in combination. Alternatively, not only the luminance of the video signal but also the color of the input video signal is changed and displayed, for example, by replacing it with a gray-based dark and low-saturated color, so that the screen luminance can be lowered as a result.

FIG. 4 is a diagram schematically illustrating the relationship between the display device and the top board according to the first embodiment of the present invention, and is a diagram illustrating another example of the relationship between the display state of the user interface and the operation unit.
In the present embodiment, the operation unit 30 is set substantially at the right end in the width direction of the top plate 11. When the viewpoint p is at the position shown in FIG. 4, a part of the display screen 21 is reflected and reflected on the operation unit 30 and can be viewed at the position of the viewpoint p. When the user interface 22 is displayed on the display screen 21, if the display screen 21 is reflected on the operation unit 30 and reflected, the user has difficulty in visually recognizing the template and hinders operability.

Therefore, when the user interface 22 to be operated using the operation unit 30 is displayed on the display screen 21, the display device 20 reduces the brightness of at least a part of the area of the display screen to darken it. In this example, the brightness of the entire area of the display screen 21 when the user interface 22 is displayed may be reduced and darkened, or the display screen reflected on the operation unit 30 can be viewed at the position of the viewpoint p. The area may be calculated, and the brightness of the screen area may be reduced to make it darker. In the case of this example, since the operation unit 30 is installed at the right end, the luminance of the display screen 21 for a part of the right end region of the display screen 21 is lowered and darkened. Further, a certain margin may be given around the calculated screen area, and the brightness of the screen may be lowered and darkened in the area where the margin is given.
In any case, when the user interface 22 to be operated using the operation unit 30 is displayed, the operation unit 30 is displayed in order to reduce the reflection by the operation unit 30 visible at the position of the viewpoint p. The brightness of at least a part of the display screen 21 including the screen area that can be reflected and viewed from the viewpoint p is reduced.

  The viewpoint position of the present embodiment is a position where the user visually recognizes the display screen in the most standard state, and when the user interface 22 to be operated using the operation unit 30 is displayed on the display screen 21, By reducing the luminance of at least a part of the area of the display screen 21, a comfortable operation can be performed without impeding visibility due to the reflection of the display screen 21 on the operation unit 30.

  In the above example, the position of the viewpoint p is set to the center position of the screen in a standard state, and the screen area for brightness adjustment can be calculated. However, the viewpoint position moves within a certain range. When the viewpoint is within the certain range, the brightness is reduced in a screen area where the reflection of the display screen 21 by the operation unit 30 is not visible at the viewpoint position regardless of the position of the viewpoint. You may calculate so that it may reduce.

(Embodiment 2)
The appearance of the image displayed on the liquid crystal panel of the liquid crystal display device differs depending on the angle (viewing angle) at which the viewer views the liquid crystal panel. For example, when the liquid crystal panel is viewed from an oblique direction, the brightness of the display image is reduced or the color tone is reversed. The viewing angle range in which the display image on the liquid crystal panel can be normally viewed is referred to as a viewing angle as an index indicating the performance of the liquid crystal display device. Note that the viewing angle is expressed as an angle centered on a perpendicular to the display surface of the liquid crystal panel. Various techniques for changing the viewing angle are known. For example, it is known that the viewing angle can be changed by changing the alignment direction of the liquid crystal molecules in the viewing angle changing liquid crystal panel arranged opposite to the liquid crystal panel. It has been.
Also, in the narrow viewing angle mode, the technology that reduces the viewing angle while maintaining the brightness in the front direction by shifting the brightness level of the image to the high brightness side while reducing the backlight brightness is known. It has been. Here, the specific method for changing the viewing angle is not limited, and the display device 20 having a function of switching the viewing angle in the vertical direction of the display device 20 by a known method is used.

  In the second embodiment according to the present invention, when the user interface 22 to be operated using the operation unit 30 is displayed on the display screen 21 and when the user interface 22 is not displayed on the display screen 21. The viewing angle of the display screen 21 of the display device 20 is switched. The user interface 22 referred to here is, for example, a software keyboard or a button for a user to perform a selection operation, as in the first embodiment. When the user interface 22 for these specific user operations is displayed, the user can operate a user interface such as a software keyboard by performing a touch operation using the operation unit 30.

In the present embodiment, when the user interface 22 to be operated using the operation unit 30 is displayed on the display screen, control is performed to narrow the viewing angle in the vertical direction. Here, it is only necessary to narrow the viewing angle with respect to at least the downward direction.
When the user interface 22 is displayed, the luminance in the downward diagonal direction from the display screen 21 is reduced by narrowing the viewing angle with respect to the downward direction. In other words, the luminance of light emitted in the direction of the operation unit 30 existing obliquely below the display screen 21 provided perpendicular to the top plate 11 is lowered. Accordingly, it is possible to prevent the visibility of the template of the operation unit 30 from being deteriorated and the operability of the operation unit 30 from being deteriorated because the display screen reflected and reflected on the operation unit 30 is visible to the user.

(Embodiment 3)
FIG. 5 is a diagram for explaining the third embodiment of the present invention, and shows an example of the relationship between the user interface displayed on the display screen and the operation unit.
In the present embodiment, when the user interface 22 to be operated using the operation unit 30 is displayed on the display screen 21, the user interface 22 is reflected on the operation unit 30 and reflected by the user. The user interface 22 is displayed at such a position that it does not exist. This prevents deterioration in operability due to the user interface 22 being reflected on the operation unit 30.

In the example of FIG. 5, the operation unit 30 is installed at a substantially right end position of the top plate 11. The operation unit 30 includes an operation template and a touch panel provided on the surface thereof. Or the operation part 30 can be comprised from the template for operation with a digital pen, and the transparent plate for protection of the display surface.
A user interface 22 for user operation can be appropriately displayed on the display screen 21. The user interface 22 for user operation is, for example, a software keyboard or a button for a user to perform a selection operation. When the user interface 22 for specific user operations is displayed, the user can operate the user interface 22 such as a software keyboard by performing a touch operation using the operation unit 30.

  The user's viewpoint position is the same as in the first embodiment. That is, the viewpoint p includes a normal line of the display screen passing through the center position of the display screen 21 and a normal line of the top plate 11 at the end position of the top plate 11 opposite to the end portion where the display device 20 is installed. It is assumed that the viewpoint p is set at the intersecting position. That is, the position of the viewpoint p is a height position that is ½ of the height H of the display screen and a position that is 1/2 (W / 2) of the width W of the display screen, and the position in the depth direction is The end position of the top plate 11 opposite to the display screen 21 is set. The distance from the viewpoint p to the display screen 21 is the same as the distance L from the display screen 21 to the end of the top plate 11.

  When the user interface 22 is displayed as shown in FIG. 5, a part of the user interface 22 (the rightmost part in this example) is reflected in the operation unit 30 and can be visually recognized at the position of the viewpoint p. Thereby, the user's visibility of the template of the operation unit 30 is deteriorated, and the operability is deteriorated. In order to avoid this, when the user interface 22 is displayed, it is displayed as shown in FIG. FIG. 6 is a diagram illustrating a display state in which the user interface 22 is not reflected on the operation unit 30.
