Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a liquid crystal display device used for image display of devices such as personal computers and televisions, and more particularly to a bezel that covers the periphery of an image display area.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a liquid crystal display device used for displaying an image of a device such as a personal computer or a television includes a liquid crystal display module that displays an image in a display area of a display surface, a front frame having an opening, a rear frame, and the like. The liquid crystal display module has a locking claw provided in the front frame in a locking hole provided in the rear frame in a state where the display area is sandwiched between the front frame and the rear frame so that the display area is exposed from the opening. It is fixed by engaging.
[0003]
In addition, some recent front frames are configured by reassessing discarding of the punched plate material when forming the opening from the viewpoint of environmental conservation and the like, and a plurality of frame frames are abutted (for example, patents) Reference 1).
[0004]
On the other hand, in recent liquid crystal display devices, an optical filter such as a protection filter that cuts off extra light such as ultraviolet rays emitted through the display area and a 3D filter that realizes autostereoscopic viewing is mounted to cover the display area. Can also be used. The optical filter is attached to the liquid crystal display device by sticking, for example, a seal to a part of the filter surface and the upper part of the front frame of the liquid crystal display device. Alternatively, it is mounted using a fixing member such as a locking claw or a screw.

Japanese Patent Laid-Open No. 2003-5156
[Problems to be solved by the present invention]
However, in the configuration of the liquid crystal display device that locks the front frame to the rear frame described above, the front frame is usually not replaced with another design, and the one that has been installed from the beginning of shipment has been used. There is a risk that the user may cause stress by continuously staring at the display area and the front frame in the periphery of the display area for a long time, and the design may be bored by the user for many years. There is sex. Even when there are front frames that can be installed in multiple types of designs, the front frame is locked to the rear frame, so it is difficult to remove, and a large burden is placed on the user to replace the front frame. It will take. Even in the configuration of Patent Document 1 described above, there is no clear description of fixing the frame frame for the liquid crystal display device to the apparatus main body, and thus there is a possibility of causing stress and tiredness to the user as described above.
[0007]
In addition, in the configuration in which the optical filter is mounted on the liquid crystal display device, when the seal is used, the display area may be difficult to see because the seal is attached to a part of the optical filter surface. On the other hand, when a fixing member such as a locking claw or a screw is used, a locking claw or a screw hole or the like must be provided on the optical filter side and the liquid crystal display side. The filter needs to be designed. Further, compared to the case where a seal is used, when a locking claw, a screw, or the like is used, the user is burdened because it is difficult to attach and detach the filter.
[0008]
In particular, mounting the 3D filter to the main unit requires alignment with the display area. If alignment is required after mounting the 3D filter, remove the 3D filter by attaching the 3D filter, etc., and then mount it again. This is very burdensome for the user. Although it is conceivable to attach the 3D filter before shipment from the factory, it is very burdensome for the operator to attach the 3D filter to the apparatus body while aligning the 3D filter with the display area. Further, there is a possibility that the position is shifted during the transportation of the apparatus and the user needs to make an adjustment again.
[0009]
On the other hand, when the optical filter is completely fixed to the apparatus main body so that it cannot be attached or detached, even if the optical filter surface is damaged and needs to be replaced, the optical filter cannot be replaced alone. In addition, when the 3D filter is completely fixed to the apparatus main body, there is a problem that a planar image cannot be displayed because a stereoscopic image is always displayed.
[0010]
An object of the present invention is to provide a liquid crystal display device in which a bezel covering a peripheral portion of a display area can be easily attached to and detached from the apparatus main body using magnetic force of a magnet.
[0011]
[Means for Solving the Problems]
In order to solve the above problems, the present invention has the following configuration.
[0012]
(1) In a liquid crystal display device comprising: a liquid crystal display module that displays an image on a display area of a display surface; and a bezel that is detachable from the apparatus main body and covers at least the periphery of the display area.
A magnet is disposed in a portion of the bezel facing the display surface, and an attracting member that is attracted by a magnetic force is provided on the surface of the display surface facing the magnet.
[0013]
In this configuration, the bezel on which the magnet is disposed at the portion facing the display surface is attracted by the magnetic force to the attracting member disposed on the surface of the display surface facing the magnet. Therefore, when the user uses the apparatus main body, the bezel that covers the periphery of the display area where the user stares is detachably attached to the apparatus main body by magnetic force, so that the user can easily attach and detach the bezel. Users can easily change bezels with different designs according to their preferences and moods. As a result, it is possible to suppress the stress generated by continuously staring at the bezel and the display area for a long time and the occurrence of design tiredness due to long-term use of the device.
[0014]
(2) The bezel includes an optical filter that covers the display area.
[0015]
In this configuration, the optical filter that covers the display area is provided on the bezel that covers the periphery of the display area, and the optical filter is detachably attached to the apparatus main body by the magnetic force of the magnet disposed on the bezel. Therefore, since the magnet, which is a member necessary for attaching / detaching the optical filter to / from the apparatus main body, is disposed in the peripheral portion of the optical filter, the optical filter surface is not shielded, and the entire image in the display area is appropriately displayed through the optical filter. Further, since the bezel can be easily attached to and detached from the apparatus main body by magnetic force, the user can easily replace the bezel and the optical filter, and the burden on the user when the optical filter is replaced is reduced.
[0016]
(3) The optical filter is a 3D filter that optically distributes the left-eye image of the stereoscopic image displayed in the display area and the right-eye image to the right eye to perform autostereoscopic viewing,
The attracting member has a surface facing the magnet that is parallel to the display surface and larger than an area of the surface facing the display surface of the magnet.
[0017]
In this configuration, the optical filter is a 3D filter that performs autostereoscopic viewing, and the surface of the attracting member that faces the magnet is larger than the area of the surface that is parallel to the display surface and that faces the display surface of the magnet. Has been.
[0018]
Therefore, since the area of the surface of the attracting member facing the magnet is larger than the surface of the attracting member facing the magnet, the bezel is easily parallel to the display surface by the user in the range of the surface of the attracting member facing the magnet. To be slid. Thereby, the user can easily adjust the position of the 3D filter relative to the display area where the user slides the bezel to perform autostereoscopic viewing.
[0019]
(4) The optical filter is characterized in that an expansion coefficient of a lens constituting the optical filter is equal to an expansion coefficient of glass constituting the display surface.
[0020]
In this configuration, since the expansion coefficient of the lens constituting the 3D filter is equal to the expansion coefficient of the glass forming the display surface, when the lens and the glass are expanded and deformed, the lens and the glass are expanded and deformed in substantially the same shape. Therefore, the position of the 3D filter with respect to the display area is not shifted, and the user does not need to adjust the position of the 3D filter with respect to the display area many times due to expansion deformation.
[0021]
(5) The optical filter is characterized in that a notch for air circulation is formed at an arbitrary position of a lens constituting the optical filter.
[0022]
In this configuration, since a notch for circulating air is formed in the lens constituting the optical filter, the display surface covered with the 3D filter touches the air in the notch for air circulation, Since the heat of the surface is released into the air, the temperature rise of the display surface is suppressed. Thereby, abnormal temperature rise is prevented, and failure of the liquid crystal display module due to abnormal temperature rise is prevented.
[0023]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a front view showing a schematic configuration of a liquid crystal display device according to an embodiment of the present invention. A liquid crystal display device 100, which is the main body of the present invention, includes a liquid crystal display module 1, a frame 2, a stand 3, a bezel 4 and the like (not shown), and is applied to a personal computer, a television, or the like as a device for displaying an image.
[0024]
As shown in FIG. 4, the liquid crystal display module 1 includes a display surface 11 having a surface for displaying an image made of glass 11 a (for example, white glass), an iron frame 50, and the like. The liquid crystal display module 1 is fixed by a chassis 15. The display surface 11 displays an image in the display area 12 excluding the peripheral portion of the display surface 11. The iron frame 50 which is the adsorption member of the present invention has a surface parallel to the display surface 11 on the display surface 11 in the peripheral portion of the display region 12.
[0025]
The frame 2 includes a front frame 21 and a rear frame 22 as shown in FIG. 4 and fixes the liquid crystal display module 1. The front frame 21 has an inner periphery substantially the same shape as the outer periphery of the liquid crystal display module 1 and covers the side surface of the liquid crystal display module 1. The rear frame 22 covers the entire rear part of the liquid crystal display module 1 opposite to the display surface 11. One end of the stand 3 is fixed to the chassis 15 and supports the liquid crystal display module 1 through the frame 2.
The bezel 4 includes an opening 41, a locking claw 42, and the like, and covers the periphery of the display area 12 so as to be detachable from the apparatus main body. The opening 41 has an inner periphery that is substantially the same shape as the outer periphery of the display region 12 and exposes the display region 12 when the bezel 4 is attached to the apparatus main body. The locking claw 42 engages with a locking hole 23 provided in the front frame 21 to lock the bezel 4 to the front frame 21. Further, the bezel 4 includes a plurality of disk-shaped magnets 43 on the surface facing the display surface 11 as shown in FIG. The magnet 43 is disposed at a position facing the iron frame 50 so as to be attracted to the iron frame 50 by magnetic force. Thereby, the bezel 4 can be attracted to the apparatus main body using the magnetic force of the magnet 43.
[0026]
Note that the locking of the bezel 4 by the locking claw 42 and the locking hole 23 is a configuration for assisting the mounting of the bezel 4 to the apparatus main body by the magnet magnetic force, and therefore the configuration using only the magnet 43. Also good. Further, since only one side of the bezel 4 is locked by the locking claw, the engagement between the locking claw 42 and the locking hole 23 can be easily released.
[0027]
Furthermore, in order to assist the mounting of the bezel 4 on the apparatus main body, the portion attracted by the magnet 43 of the iron frame 50 may be formed in a concave shape. Thereby, since the magnet 43 can be inserted into the concave shape portion, the magnet 43 attracted to the iron frame 50 can be prevented from shifting, and the bezel 4 can be more appropriately attached to the apparatus main body.
[0028]
As described above, when the user uses the apparatus main body, the bezel 4 covering the periphery of the display area 12 that the user gazes is detachably attached to the apparatus main body by magnetic force. The user can easily replace the bezel 4 with a different design according to the user's preference and mood. As a result, it is possible to suppress the stress generated when the user keeps staring at the bezel 4 and the display area 12 for a long time and the tiredness of the design due to the long-term use of the apparatus. In addition, since the user can easily attach the bezel 4, the burden on the user when the bezel 4 is attached and detached can be reduced.
[0029]
In the embodiment of the present invention, a plurality of disk-shaped magnets 43 are used. However, the present invention is not limited to this, and the size and weight of the bezel 4 and ease of attachment / detachment by the user are considered. Then, the number, shape, and type of magnets may be set.
[0030]
In the embodiment of the present invention, the bezel 4 having the opening 41 is used, but the invention is not particularly limited thereto. The left-eye image and the right-eye image of the stereoscopic image displayed in the display area 12 such as a protective filter that cuts off ultraviolet rays or the like emitted through the display surface 11 and the lenticular type, deflection type, and barrier type are displayed. An optical filter such as a 3D filter (optical stereoscopic filter) that optically distributes light to the right eye and performs autostereoscopic viewing is fixed to the opening 41, and the optical filter covers the display region 12 when the bezel 4 is attached. The bezel 4 may be used. In addition to the optical filter, a configuration using a touch panel is also possible.
[0031]
As a result, the magnet 43 necessary for attaching to and detaching from the apparatus main body is disposed on the bezel 4 covering the peripheral portion of the optical filter, so that the optical filter surface is not shielded by the members necessary for attachment to and detachment from the apparatus main body. Through this, the entire image in the display area can be appropriately displayed. In addition, since the bezel 4 can be easily detached from the apparatus main body, the user can easily replace the bezel 4 and the optical filter, and the burden on the user when the optical filter is replaced can be reduced. .
[0032]
A lenticular type 3D filter 60 will be described as a specific example of the bezel 4 including the optical filter. As shown in FIGS. 3 and 4, the 3D filter 60 fixed to the opening 41 of the bezel 4 includes a bowl-shaped lenticular lens 60 a that is a lens of the present invention. As shown in FIG. 4, the 3D filter 60 is attached to the apparatus main body so as to contact the display surface 11. This is because when a gap is provided between the display surface 11 and the 3D filter 60, the light of the stereoscopic image emitted from the liquid crystal display module 1 via the display surface 11 is appropriately 3D filtered by refraction or reflection. This is because the three-dimensional image is not displayed accurately without passing through 60. Further, in the 3D filter 60, the cross section of the peripheral portion 60 b has a substantially L shape in accordance with the protruding shape around the display surface 11. Further, the 3D filter 60 is bonded to the bezel 4 with a double-sided tape affixed to the surface of the peripheral portion 60 b facing the bezel 4.
[0033]
On the other hand, the surface of the iron frame 50 facing the magnet 43 is formed larger than the area of the surface of the magnet 43 facing the iron frame 50. Thus, the bezel 4 can be slid in the range of the surface facing the magnet 43 of the iron frame 50, and the vertical and horizontal positions of the 3D filter 60 with respect to the display area 12 can be adjusted. Can do.
[0034]
However, the bezel 4 can be slid only to a position where the peripheral portion 60b of the 3D filter 60 contacts the protruding portion of the peripheral portion of the display surface 11. In other words, the display area 12 that does not face the bowl-shaped lenticular lens 60a is not stereoscopically viewed by the user, and thus the range in which the display area 12 can slide is limited so as to always face the lenticular lens 60a.
[0035]
The locking claw 42 and the locking hole 23 are configured such that the bezel 4 can slide by forming the locking hole 23 larger than the width of the locking claw 42 in the left-right direction.
[0036]
On the other hand, the lenticular lens 60a constituting the 3D filter 60 is made of a material having an expansion coefficient equivalent to that of the glass 11a constituting the surface of the display surface 11 so as to expand and deform into substantially the same shape. This is to prevent the position of the 3D filter 60 from being shifted with respect to the display region 12 due to expansion deformation due to heat. That is, since the 3D filter 60 is in contact with the display surface 11, heat is transmitted from the display surface 11, and the temperature becomes substantially equal to that of the display surface 11. Therefore, if the expansion ratios of the lenticular lens 60a and the glass 11a are different, the lenticular lens 60a and the glass 11a are expanded and deformed into different shapes. Therefore, the position of the 3D filter 60 with respect to the display area 12 is shifted, and the user has to adjust the position of the 3D filter 60 many times.
[0037]
As in the configuration of the above-described example, the bezel 4 includes the 3D filter 60, and the user can increase the area of the surface facing the magnet 43 of the iron frame 50 more than the surface facing the display surface 11 of the magnet 43. The bezel 4 can be slid parallel to the display surface 11. Accordingly, the user can easily adjust the position of the 3D filter 60 with respect to the display region 12 by sliding the bezel 4.
[0038]
Further, as shown in FIG. 5, an air circulation notch 65 may be provided around the 3D filter 60. This
Since the display surface 11 covered with the 3D filter 60 can touch the air in the air distribution notch 65 and release the heat of the display surface 11 into the air, the temperature rise of the display surface 11 can be suppressed. . Therefore, abnormal temperature rise of the display surface 11 can be prevented, and failure of the liquid crystal display module 1 due to abnormal temperature rise can be prevented.
[0039]
In the embodiment of the present invention, the bezel is attached to the apparatus main body using the magnet 43, but the liquid crystal display device 100 is not particularly affected by the magnetic force.
[0040]

In addition, since the user can easily attach and detach the bezel, the burden on the user when attaching and detaching the bezel can be reduced.

[0044]
(4) By making the expansion coefficient of the lens constituting the 3D filter equal to the expansion coefficient of the glass constituting the display surface, when the lens and the glass are inflated and deformed, the glass and the lens are inflated and deformed in substantially the same shape. Therefore, the position of the 3D filter with respect to the display area can be prevented from shifting.
[0045]
