Abstract

<P>PROBLEM TO BE SOLVED: To prevent a sense of incongruity from being given to an observer caused by the presence of a non-display area around a display area to form so-called frame area. <P>SOLUTION: A front cabinet 2 is arranged which has an optical member 200 formed along peripheral edges of a panel module 1 and a back cabinet 3 fixed to the panel module 1. Areas overlapping a non-display area 11b on the front side and the rear side of the panel module 1 when viewed from the side of a display surface 1a are covered from the side face side of the panel module 1 by the optical member 200, and light on the back of the areas overlapping the non-display area 11b is led from the rear side to the front side of the panel module 1 to display a background image in a part of the front side so that the observer on the side of the display surface 1a can view it. Thus, it looks as if the front cabinet 2 didn't exist, so that a state equivalent to the absence of the frame area is achieved. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to an electro-optical device including a flat panel display such as a liquid crystal display panel.

  Conventionally, a liquid crystal display device as an electro-optical device is used as a display panel, and is mounted on an electronic device such as a notebook personal computer or a liquid crystal television. In these electronic devices, it is necessary to accommodate the liquid crystal display device in a limited space inside the housing, and in order to increase the amount of information that can be displayed by the liquid crystal display device, the display area of the liquid crystal display device is made as much as possible. A configuration in which the area outside the display area, that is, the non-display area is narrowed is desired. Note that the non-display area is sometimes referred to as a frame area.

As a display device capable of narrowing the non-display area, for example, when a driving IC for performing drive control of a liquid crystal display device and a wiring connected to the driving IC are arranged in the non-display area. There has been proposed a technique in which the range of the non-display area is narrowed by adjusting the arrangement position (see, for example, Patent Document 1). In addition, when a double-sided adhesive tape is attached to the non-display area and the liquid crystal display panel and the backlight unit are fixed with the double-sided adhesive tape, it is necessary to secure a sufficient area to fix them. In view of the above, we propose that the non-display area is narrowed by forming the polarizing plate into a shape that can fix the liquid crystal display panel and the backlight unit instead of sticking with double-sided adhesive tape. (For example, refer to Patent Document 2).
Japanese Patent Laid-Open No. 2002-140015 JP 2007-164057 A

However, in either method, although the non-display area can be narrowed, the non-display area cannot be completely eliminated, and some non-display area remains. For this reason, when this liquid crystal display panel is incorporated into a housing of a personal computer or a liquid crystal television, it is necessary to arrange an outer frame that covers this non-display area.
Some viewers of liquid crystal televisions feel uncomfortable with such an outer frame from the viewpoint of aesthetic sense. For example, when viewing an image of a magnificent scenery on a large television, an inorganic outer frame is included in the field of view, so it may be felt that the atmosphere obtained from the image is broken.
Accordingly, the present invention has been made paying attention to the above-mentioned conventional unsolved problems, and in an electro-optical device such as a flat panel display such as a liquid crystal display panel, a non-display area exists around the display area. It is to eliminate the uncomfortable feeling that occurs.

In order to solve the above-described problems, an electro-optical device according to the present invention includes a panel module having a display area and a display surface on which a non-display area is arranged on the outer periphery of the display area, and a display surface of the panel module. When viewed from the side, light from the back part of the area overlapping the non-display area of the panel module is incident, the light bypasses the outside of the end face of the panel module, and the non-display area on the display surface side of the panel module And an optical member that emits light from the overlapping region.
This allows the viewer on the display surface side to see the background displayed in the area that overlaps the non-display area of the panel module, so that the same situation as when there is no non-display area on the display surface can be realized. it can.

  Further, in the above-described electro-optical device, the optical member is installed on the back surface of the panel module so as to overlap the non-display area when viewed from the display surface side, and an incident surface on which light from the back is incident, An emission surface that is installed on the display surface side of the panel module so as to overlap the non-display region and emits light incident on the incident surface, and the incident surface and the emission surface are at the end of the display region side. The unit is installed so as to overlap with a boundary position between the non-display area and the display area or to partially overlap the display area.

This prevents the viewer on the display surface side from seeing the background of the non-display area overlapping the display area, and avoiding giving a sense of incongruity by displaying the background overlapping the display area. .
In the electro-optical device described above, a plurality of reflecting surfaces that guide light incident on the incident surface to the emitting surface are provided.
Since the light incident on the incident surface is guided to the output surface by repeated reflection, it can be easily guided without causing chromatic aberration.

In the electro-optical device described above, a first transmission surface, a part of which forms the incident surface, and a first reflection surface that reflects light incident on the incident surface toward the first transmission surface; The first transmission surface and the first reflection surface have an incident angle when reflected light of the first reflection surface is incident on the first transmission surface. It is characterized in that it is installed at an angle larger than the critical angle of the transmission surface.
Since the incident surface not only enters light but also acts as a surface that reflects light, the number of reflecting surfaces can be reduced accordingly.

  The electro-optical device described above further includes a second transmission surface, part of which forms the emission surface, and a second reflection surface that reflects incident light toward the second transmission surface. The angle between the second transmission surface and the second reflection surface when the reflected light of the second reflection surface is incident on the second transmission surface is the critical value of the second transmission surface. It is characterized by being installed at an angle larger than the corner.

Since the emission surface not only emits light but also acts as a surface that reflects light, the number of reflection surfaces can be reduced accordingly.
In the electro-optical device described above, the light incident on the incident surface is reflected an even number of times and guided to the exit surface.
As a result, the background image displayed on the exit surface can be displayed as an upright image without being horizontally reversed.

  Further, in the electro-optical device according to the aspect of the invention, the optical member reflects the light incident on the incident surface when viewed from the display surface side, and collects the light at a focal point set outside the end surface of the panel module. A first parabolic mirror and a second parabolic mirror that is placed at a position symmetrical to the first parabolic mirror across the panel module and has the same focal point as the first parabolic surface. A parabolic mirror; and a reflecting surface that is disposed perpendicularly to an axis of symmetry formed by the first and second parabolic mirrors at a focal position of the first parabolic mirror. Yes.

  In the electro-optical device according to the aspect of the invention, the optical member may be a first paraboloid that reflects light incident on the incident surface and collects the light on the outside of the panel module end surface when viewed from the display surface side. A first parabolic mirror, a second parabolic mirror installed at a position symmetrical to the first parabolic mirror across the panel module, and one or a plurality of reflecting surfaces. A first reflecting structure for guiding reflected light of an object mirror to a focal point set on an axis of symmetry formed by the first and second paraboloid mirrors through the one or more reflecting surfaces; And a second reflecting structure installed at a position symmetrical to the first reflecting structure about an axis of symmetry formed by the second parabolic mirror, and the first and second parabolas at the focal point. And a single reflecting surface that is installed perpendicularly to the axis of symmetry formed by the surface mirror.

  In the electro-optical device described above, the first reflecting structure is a transmission surface that partially forms the incident surface, and the reflected light of the first parabolic mirror is incident, and the incident angle is a critical angle. A first transmission surface installed at a larger angle than the first reflection surface, wherein the second reflection structure has the first and second parabolic mirrors as axes of symmetry. It has the 2nd transmission surface installed in the position symmetrical with a transmission surface, It is characterized by the above-mentioned.

  In the electro-optical device described above, the first reflecting structure is a transmission surface that partially forms the incident surface, and the reflected light of the first parabolic mirror is incident, and the incident angle is a critical angle. A first transmission surface that is installed to have a larger angle, and a first reflection surface that reflects the reflected light of the first transmission surface toward the one reflection surface and collects the light at the focal point. The second reflecting structure is symmetrically positioned with respect to each of the first transmitting surface and the first reflecting surface with respect to an axis of symmetry formed by the first and second parabolic mirrors. A second transmission surface and a second reflection surface are provided.

Thus, by using a parabolic mirror, the number of reflections when the light incident on the incident surface is guided to the output surface can be reduced as compared with the case where only the reflective surface is used.
Further, in the above-described electro-optical device, as viewed from the display surface side of the panel module, from the back portion that is incident on a region outside the end face of the panel module and not overlapping the incident surface and the emission surface, of the optical member. The light is transmitted and emitted as it is.

Thereby, when viewed from the display surface side, the background image appears to be displayed in the area overlapping the non-display area, and the background image appears to be transmitted as it is in the area not overlapping the non-display area. A so-called frame area around the display area is not seen, that is, a state equivalent to the case where no frame area exists can be realized.
In the electro-optical device described above, an optical path length in a transmission optical path of light incident on the incident surface in a region overlapping with the non-display region on the incident side or the emission side of the optical member when viewed from the display surface side. A difference adjustment relay lens is arranged.

Furthermore, in the electro-optical device described above, at least one of the first parabolic mirror and the second parabolic mirror absorbs an optical path length difference in a transmission optical path of light incident on the incident surface. It is formed as follows.
In this way, by arranging the relay lens for adjusting the optical path length difference or adjusting the parabolic mirror, the background image visible to the observer can be made a clear background image without distortion.

Embodiments of the present invention will be described below.
First, a first embodiment will be described.
First, the configuration will be described.
FIG. 1 is an example of a schematic perspective view of an exploded liquid crystal television 100 to which the present invention is applied.
As shown in FIG. 1, the liquid crystal television 100 includes a panel module 1, a front cabinet 2, and a back cabinet 3.

  The panel module 1 includes a substantially plate-like panel portion 11 and a flange portion 12 that is continuous with the periphery of the panel portion 11. The panel unit 11 includes a liquid crystal display panel, a backlight unit, and electrical components such as a circuit board and a power supply board for driving and controlling the liquid crystal display panel and the backlight unit. A display area 11a for displaying television images is formed at substantially the center of one surface of the panel unit 11, and an IC for driving a liquid crystal display panel and the driving IC and a circuit board are connected around the display area 11a. A non-display area 11b is formed in which wirings and the like are arranged.

The front cabinet 2 is formed in a rectangular frame shape that surrounds the peripheral edges of the panel module 1 and the back cabinet 3. The front cabinet 2 is composed of an optical member made of an optical material such as glass or quartz having a transmission surface and a reflection surface.
The back cabinet 3 includes a cover portion 31 that covers and accommodates the panel portion 11 of the panel module 1 from the back side, and a flange portion 32 that continues to the periphery of the cover portion 31 and faces the flange portion 12 of the panel module 1.

2A and 2B are views showing details of the left frame portion constituting the front cabinet 2 when viewed from the front, wherein FIG. 2A is a cross-sectional view taken along the line AA ′ of FIG. 1, and FIG. is there.
As shown in FIG. 2, the front cabinet 2 is formed of an optical member 200 having a substantially inverted S-shaped cross section, and the optical member 200 has a recess 101. The outer surface of the optical member 200 is composed of a plurality of planes.

The panel module 1 and the back cabinet 3 are schematically represented as the panel module 1 in FIG. Further, the non-display area 11b and the flange portion 12 of the panel module 1 are schematically shown as the non-display area 11b in FIG.
In the description of FIG. 2, the positional relationship viewed from the display surface 1 a side of the panel module 1 will be described.

As shown in FIG. 2, the dent 101 includes a bottom surface 101a and side surfaces 101b and 101c formed on both sides of the bottom surface 101a. And it arrange | positions so that the bottom face 101a and the side surface of the panel module 1 may oppose.
The optical member 200 includes an incident-side transmission surface 111, reflection surfaces 112 to 114, 116, and 118, a transmission surface 115, and an emission-side transmission surface 117. The reflection surfaces 112 to 114, 116, and 118 are Each of them has a reflecting mirror such as an aluminum foil attached to the outer periphery to form a plane mirror.

The transmission surface 111 is located on the rear side of the panel module 1 when the panel module 1 is accommodated in the recess 101. In addition, the transmission surface 111 makes the light (background) of the regions W1 and W3 behind the transmission surface 111 viewed from the display surface 1a side enter the optical member 200.
The transmission surface 111 reflects light incident at an angle larger than the critical angle. Therefore, as described later, since the reflected light of the reflecting surface 112 is incident at an incident angle larger than the critical angle, the reflected light of the reflecting surface 112 is totally reflected by the transmitting surface 111. In other words, the transmissive surface 111 acts as a transmissive surface on which light is incident, and also acts as a reflective surface that totally reflects the reflected light from the reflective surface 112.
The reflection surface 112 reflects light incident from the transmission surface 111 in the direction of the reflection surface 113 described later. Further, the reflection surface 112 is arranged such that the incident angle when the reflected light of the reflection surface 112 is incident on the transmission surface 111 is larger than the critical angle of the transmission surface 111.

  The reflective surface 112 has a width that overlaps with the non-display region 11b of the panel module 1 when viewed from the display surface 1a side when the panel module 1 is accommodated in the depression 101, and the display region of the reflective surface 112 The end on the 11a side is arranged so as to overlap with the boundary position between the non-display area 11b and the display area 11a or a position slightly closer to the display area 11a than the boundary position. That is, as will be described later, the background image detoured by the optical member 200 and emitted from the front side is adjacent to the display image of the display area 11a at the boundary position between the display area 11a and the non-display area 11b, or The background image is arranged so as to partially overlap the display area 11a. At this time, the viewer does not interfere with the display image of the display area 11a because the background image appears to be superimposed on the display area 11a. It is arranged to overlap.

The reflection surface 113 reflects the reflected light totally reflected by the transmission surface 111 in the direction of the reflection surface 114 described later.
The reflective surface 114 forms a rear side surface of the recess 101, that is, a side surface 101b which is the rear side of the panel module 1, and reflects the reflected light of the reflective surface 113 toward a transmission surface 115 described later.

The transmissive surface 115 is disposed in parallel with the transmissive surface 111 such that the position in the front-rear direction viewed from the display surface 1 a is between the reflective surface 112 and the reflective surface 114. Further, the transmission surface 115 receives the reflected light of the reflection surface 114 and totally reflects it toward the reflection surface 116 described later.
Here, the transmission surface 115 and the reflection surface 114 are arranged such that the incident angle when the reflected light of the reflection surface 114 is incident on the transmission surface 115 is larger than the critical angle of the transmission surface 115. The For this reason, the transmission surface 115 totally reflects the reflected light of the reflection surface 114. Further, the transmission surface 115 receives and transmits the light (background) of the back portion of the region W2 that does not overlap the reflection surface 112.
That is, the transmission surface 115 functions as a transmission surface that transmits light (background) behind the region W2, and also functions as a reflection surface that totally reflects the reflected light of the reflection surface 114.
The reflection surface 116 reflects the reflected light of the transmission surface 115 toward the transmission surface 117 described later.

  When the panel module 1 is accommodated in the recess 101, the transmission surface 117 is disposed in front of the side surface 101 c on the front side of the recess 101 and in parallel with the transmission surface 111 and the transmission surface 115. Further, the transmission surface 117 totally reflects the reflected light of the reflection surface 116. Here, the transmission surface 117 and the reflection surface 116 are arranged at an angle at which the incident angle when the reflected light of the reflection surface 116 enters the transmission surface 117 is larger than the critical angle of the transmission surface 117. The The transmission surface 117 transmits and transmits the light transmitted through the transmission surface 115 as it is, and totally reflects the reflected light of the reflection surface 116 toward the reflection surface 118. Further, the transmission surface 117 transmits the reflected light incident perpendicularly from the reflection surface 118 as it is and emits it. That is, the transmission surface 117 functions as a reflection surface that totally reflects the reflected light of the reflection surface 116, and also functions as a transmission surface that vertically transmits the transmission light that has transmitted through the transmission surface 115 and the reflection light of the reflection surface 118.

The reflection surface 118 forms a side surface 101 c on the near side of the recess 101, and reflects the reflected light reflected by the transmission surface 117 toward the reflection surface 118. Here, the transmission surface 117 and the reflection surface 118 are arranged so that the reflected light of the reflection surface 118 is emitted vertically from the transmission surface 117.
Further, the reflective surface 118 has a width that overlaps with the non-display area 11b of the panel module 1 when the panel module 1 is accommodated in the recess 101, and has the same width as the reflective surface 112 when viewed from the display surface 1a side. It is formed.

And each reflective surface 112-114,116,118 and the transmissive surfaces 111,115,117 see the background of the area | region W1 which injects into the reflective surface 112 via the transmissive surface 111 seeing from the display surface 1a side, and transmission. They are arranged so that the background image made of the light emitted from the surface 117 coincides.
For this reason, as shown in FIG. 2, for the observer on the display surface 1a side, in the transmission surface 117 disposed on the front surface of the optical member 200, the region W1 overlapping the reflection surface 112 coincides with the background of this region W1. The background image to be displayed is displayed on the transmission surface 117. Further, in a region W2 of the transmissive surface 115 that does not overlap the reflective surface 112, the background of this region W2 is transmitted through the transmissive surface 115 and emitted from the transmissive surface 117 as it is. Therefore, when viewed from the display surface 1a side, the background image of the region (W1 + W2) overlapping with the transmission surface 117 is displayed on the transmission surface 117 and seen.

Further, in the region W3 of the transmission surface 111 that does not overlap the reflection surface 112, the light (background) transmitted through the transmission surface 111 is reflected by the reflection surface 114 and is not transmitted to the transmission surface 117 side.
Therefore, as shown in FIG. 2, when the panel module 1 is accommodated in the depression 101 and viewed from the front side, the non-display area 11b of the panel module 1 is covered by the front cabinet 2, that is, the optical member 200. Only the second transmissive surface 117 and the display area 11a are visible. Since the background image of the area W1 that overlaps the non-display area 11b of the panel module 1 and the background image of the area W2 that passes through the transmission surface 115 are displayed on the transmission surface 117, the observation on the display surface 1a side is observed. It seems to the person as if the front cabinet 2 does not exist. That is, only the display area 11a of the liquid crystal television 100 can be seen, and only the display image of the liquid crystal television 100 can be seen floating in the background.

FIG. 3 is a schematic view showing a mounting portion of the front cabinet 2, the panel module 1 and the back cabinet 3. 3 shows a cross-sectional view of a mounting portion on the left side when the liquid crystal television 100 is viewed from the front side.
The panel module 1 and the back cabinet 3 overlap the flange portion 12 of the panel module 1 and the flange portion 32 of the back cabinet 3 in a state where the panel portion 11 of the panel module 1 is accommodated in the cover portion 31 of the back cabinet 3. Then, it is fixed by screwing from the flange portion 12 side.

The front cabinet 2 is arranged so as to cover these fixed end face of the panel module 1 and the back cabinet 3, and the front cabinet 2 and the back cabinet 3 are fixed by a plurality of mounting members 5 arranged in a distributed manner.
The attachment member 5 has a holding part 51 and a base part 53. The base portion 53 is formed in a plate shape and is fixed to the back surface of the back cabinet 3. The holding portion 51 is provided so as to stand substantially vertically from the substantially center of the base portion 53, and has a key shape that is bent so as to be parallel to the base portion 53. Forms the “U” -shaped member of Katakana. And the front cabinet 2 is hold | maintained by this convex-shaped member formed by the "U" -shaped member, the transmission surface 111 of the front cabinet 2, and the reflective surfaces 113 and 114 fitting. The front cabinet 2 and the back cabinet 3 are fixed by, for example, screwing the base portion 53 to the back surface of the back cabinet 3 from the base portion 53 side while holding the convex portion 2a as described above. The panel module 1 is sandwiched between the front cabinet 1 and the back cabinet 3, and these are fixed.

Further, the front cabinet 2 is actually formed by being divided into a plurality of members, and each of the divided members of the front cabinet 2 is attached to the panel module 1 and the back cabinet 3 and the members are fixed to each other. To make a frame.
For example, in the rectangular frame-shaped front cabinet 2, when viewed from the front side of the liquid crystal television 100, the front cabinet 2 is divided into an upper member composed of members corresponding to the upper side and the left and right sides and a lower member composed of members corresponding to the lower side. Alternatively, each of the four sides of the rectangle may be provided as an individual member, or the two adjacent sides may be used as one member and the two members may be abutted. What is necessary is just to divide | segment so that the observer of the liquid crystal television 100 may not feel uncomfortable about the joint part which joins each divided part.

In addition, when making two adjacent sides into one member, the corner | angular part, for example, the shape which formed the edge part which comprises the corner | angular part of each optical member diagonally, and butted each optical member, or each What is necessary is just to form in the shape which joined the edge parts which comprise the corner | angular part of an optical member in circular arc shape.
As shown in FIG. 3, since a gap is formed between the front cabinet 2 and the display module 1a side end portion of the panel module 1, for example, a frame-shaped buffer member is interposed therebetween. The front cabinet 2 and the panel module 1 may be more securely fixed and foreign matter such as dust may be prevented from being mixed inside.

In addition, a speaker, an input / output terminal, and the like, which are components of the liquid crystal television 100, may be provided on the back side or provided separately.
Moreover, the fixing method of the panel module 1, the front cabinet 2, and the back cabinet 3 is not restricted to this, What kind of method may be used as long as these can be fixed.

Next, the operation of the first embodiment will be described.
4A is a front view of the liquid crystal television 100, FIG. 4B is a front view of the liquid crystal television 100 visible to an observer, and FIG. 4C is a front view of a conventional liquid crystal television.
As shown in FIG. 4A, the liquid crystal television 100 viewed from the front side can see the frame-like region 100a formed of the transmission surface 117 of the front cabinet 2 and the display region 11a.

  Here, the front cabinet 2 is configured by the optical member 200 as described above, and the light in the back portion of the region overlapping the transmission surface 117 when viewed from the front side is emitted from the transmission surface 117. For this reason, the front cabinet 2 actually exists, but light from the back of the front cabinet 2 is emitted from the transmission surface 117, that is, the frame-shaped region 100a. The image will be displayed. That is, as shown in FIG. 4B, when the liquid crystal television 100 is arranged on the wall and the wallpaper has a floral pattern, the observer can also see the frame-shaped region 100a as a floral pattern. The front cabinet 2 looks as if it were, and only the display area 11a is visible.

Therefore, a state equivalent to the case where the non-display area 11b does not exist even though the display area 11a of the panel module 1 has the non-display area 11b in which drive circuits, wirings, and the like are arranged is realized. Can do.
Here, as in the conventional case shown in FIG. 4 (c), when the non-display area in which the drive circuit, wiring, and the like are arranged is hidden by the front cabinet, from the observer, the front is displayed around the display area 11a. The cabinet appears to exist. For this reason, a so-called frame area appears to exist around the display area 11a, which may give the viewer of the liquid crystal television 100 a sense of discomfort. However, in the first embodiment, as shown in FIG. 4B, since the frame area does not exist in appearance, it can be avoided that the viewer feels uncomfortable. In particular, when a liquid crystal television is arranged in a relaxing place such as a living room, only the display image of the liquid crystal television 100 appears to be lifted, and a fantastic atmosphere can be created.

In addition, as shown in FIG. 2, the optical member 200 is configured by a reflection surface and a transmission surface, and is configured to reflect the light eight times and emit the light from the transmission surface 117. Therefore, the background image is not inverted vertically and horizontally.
Further, since the transmission surfaces 111, 115, and 117 are used as the transmission surface and the reflection surface, the number of surfaces of the optical member 200 can be reduced accordingly.

Further, the reflection surfaces 112 to 114, 116, and 118 are provided with a reflection film so as to be totally reflected, and when the transmission surfaces 111, 115, and 117 are used as reflection surfaces, the reflection surfaces 112 to 114, 116, and 118 are totally reflected. Therefore, it is possible to prevent a decrease in the amount of light upon reflection on each surface, and a background image that can be seen by the observer can be a clear background image.
In addition, since the background image is transmitted only by reflection, the background image visible to the observer can be made a clear background image without causing chromatic aberration.

In the first embodiment, the case where the optical member 200 is formed in an inverted S shape when viewed from the display surface 1a side as shown in FIG. 2 is described, but the present invention is not limited to this. Any configuration may be used as long as the configuration reflects eight times. Further, the number of reflections is not limited to eight. In order to obtain a background image that is not inverted vertically and horizontally, it is only necessary to reflect the even number of times.
In addition, in the case of an odd number of times, the observer sees the background image reversed, but for example, when the background is plain, such as when the background is reversed, the observer reflects the odd number of times. It may be an optical member.

  In the first embodiment, since the optical path length difference occurs, the background image may appear distorted on the transmission surface 117. In this case, for example, as shown in FIG. 5, by providing a frame-shaped relay lens 100b at a position overlapping the front cabinet 2 when viewed from the front side, a background image transmitted to the front side of the front cabinet 2 is displayed. You may make it absorb distortion. The relay lens 100b may be disposed on either the front side or the back side of the liquid crystal television 100, but may be disposed on the back side, for example, in view of appearance. Moreover, it is not necessarily limited to the frame shape, and a columnar relay lens may be disposed only on the left and right sides of the liquid crystal television 100 as necessary.

Here, in the first embodiment, a region overlapping the region W1 of the transmission surface 111 when viewed from the display surface 1a side corresponds to the incident surface, and a region overlapping the region W1 of the transmission surface 117 corresponds to the emission surface. ing.
Further, the transmission surface 111 corresponds to the first transmission surface, the reflection surface 112 corresponds to the first reflection surface, the transmission surface 117 corresponds to the second transmission surface, and the reflection surface 116 corresponds to the second reflection surface. It corresponds to.

Next, a second embodiment of the present invention will be described.
Since the second embodiment is the same as the first embodiment except that the optical path of the optical member 200 is different and the shape of the front cabinet 2 is different, the same parts are given the same reference numerals, Detailed description thereof is omitted.
FIG. 6 is a diagram showing a configuration of the front cabinet 2 in the second embodiment. It is a figure which shows the left side frame part which comprises the front cabinet 2 seeing from the front side, Comprising: (a) is a horizontal sectional view, (b) is a perspective view.

As shown in FIG. 6, the front cabinet 2 is configured so that the cross section is axisymmetric, and has a recess 201 that accommodates the end portions of the panel module 1 and the back cabinet 3 at a position that is an axis of line symmetry. The outer surface of the optical member 200 includes a plurality of planes and two paraboloids.
The panel module 1 and the back cabinet 3 are schematically represented as the panel module 1 in FIG. Further, the non-display area 11b and the flange portion 12 of the panel module 1 are schematically represented as the non-display area 11b in FIG.

Moreover, in description of FIG. 6, it demonstrates as a positional relationship seen from the display surface 1a side of the panel module 1. FIG.
As shown in FIG. 6, the recess 201 is formed by abutting the end portions of side surfaces 201 a and 201 b made of a paraboloid.
As shown in FIG. 6, the optical member 300 includes an incident-side transmission surface 211, an incident-side paraboloid 212, a reflection surface 213, an emission-side paraboloid 214, and an emission-side transmission surface 215. . Reflective films such as aluminum foil are attached to the outer periphery of the paraboloidal surfaces 212 and 214 and the reflective surface 213 to form a parabolic mirror and a plane mirror, respectively.
When the panel module 1 is accommodated in the depression 201, the transmission surface 211 is positioned behind the panel module 1 when viewed from the display surface 1a side of the panel module 1, and receives light (background) on the back of the transmission surface 211. This is transmitted.

  The parabolic surface 212 forms one side surface 201a of the depression 201, and reflects incident light transmitted through the transmission surface 211 toward a reflection surface 213 described later. Further, the focal point X of the paraboloid 212 is arranged so as to be positioned on the reflection surface 213. The paraboloid 212 has a width that overlaps the non-display area 11b of the panel module 1 when the panel module 1 is accommodated in the depression 201, and the display area of the reflection surface 212. The end portion on the 11a side is arranged at a boundary position between the non-display area 11b and the display area 11a or a position slightly closer to the display area 11a than the boundary position. That is, as will be described later, the background image detoured by the optical member 300 and emitted from the front side is adjacent to the display image of the display area 11a at the boundary position between the display area 11a and the non-display area 11b, or The background image is arranged so as to partially overlap the display area 11a. At this time, the background image appears to be superimposed on the display area 11a to the observer, thereby obstructing the display image of the display area 11a from the viewpoint of the observer. It is arranged to overlap so as not to become.

The reflection surface 213 is disposed perpendicular to the transmission surface 211 at the position of the focal point X of the paraboloid 212, and reflects reflected light from the paraboloid 212 toward a paraboloid 214 described later.
The paraboloid 214 forms the other side surface 201b of the depression 201 and is arranged to face the end of the paraboloid 212 on the display area 11a side. In addition, the paraboloid 214 has a focal point at the same position as the focal point X of the paraboloid 212, and a line segment that connects the junction point of the paraboloid 212 and the paraboloid 214 and the focal point X is an axis. The paraboloid 214 and the paraboloid 212 are in a line-symmetric relationship. For this reason, the paraboloid 214 receives the reflected light of the reflection surface 213, converts it into parallel light perpendicular to the transmission surface 211, and reflects it.

The paraboloid 214 has the same width as the paraboloid 212, and the end of the display area 11a is disposed at a position overlapping the end of the paraboloid 212 on the display area 11a.
The transmission surface 215 is in a line-symmetric relationship with the transmission surface 211 about the same axis as the axis of line symmetry of the paraboloids 212 and 214. For this reason, the transmission surface 215 is arranged in parallel with the transmission surface 211, and the incident light transmitted through the transmission surface 211 enters perpendicularly, and is transmitted as it is, and is reflected by the paraboloid 214. The parallel light thus made is incident vertically and emitted as it is.

  Therefore, as shown in FIG. 6, in the transmission surface 215, in the region W11 overlapping with the paraboloids 212 and 214 when viewed from the display surface 1a side, the light of the back overlapping this region W11 is emitted, and the paraboloid 212 In the region W12 that does not overlap with the region 214, the light of the back portion that overlaps the region W2 is transmitted through the transmission surface 211 and is emitted from the transmission surface 215 as it is. For this reason, the background image of the area overlapping the transmission surface 215 when viewed from the display surface 1a side is displayed on the transmission surface 215.

  For this reason, as shown in FIG. 6, when the panel module 1 is accommodated in the depression 201 and viewed from the display surface 1 a side, the non-display area 11 b of the panel module 1 is covered by the front cabinet 2. Only the transparent surface 215 and the display area 11a are visible. At this time, the light on the back of the front cabinet 2 is emitted directly or reflected from the transmission surface 215, so that the viewer on the display surface 1 a side has a non-display area 11 b of the panel module 1 on the transmission surface 215. The background image of the region W11 and the background image of the region W12 overlapping with each other are displayed and viewed. Therefore, since it looks to the observer as if the front cabinet 2 does not exist, only the display area 11a of the liquid crystal television 100 can be seen in this case as well.

FIG. 7 is a schematic configuration diagram of a mounting portion of the front cabinet 2, the panel module 1, and the back cabinet 3. FIG. 7 shows a cross-section of the attachment portion on the left side when the liquid crystal television 100 is viewed from the front side.
Similar to the first embodiment, the panel module 1 and the back cabinet 3 are configured such that the panel portion 11 of the panel module 1 is accommodated in the cover portion 31 of the back cabinet 3 and the flange portion 12 of the panel module 1 The flange part 32 of the back cabinet 3 is overlapped and fixed by screwing from the flange part 12 side or the like.
A front cabinet 2 is arranged on the fixed panel module 1 and the back cabinet 3 so as to cover these end faces, and the front cabinet 2 and the back cabinet 3 are fixed by a plurality of mounting members 7 arranged in a distributed manner. Is done.

  The attachment member 7 includes a holding portion 71 and a base portion 73 formed integrally with the holding portion 71. The holding portion 71 is bent and extended along the transmission surface 211 from the transmission surface 211 side portion of the reflection surface 213, and is substantially parallel to the reflection surface 213 at the end of the transmission surface 211 on the paraboloid surface 212 side. It is bent and has the shape of an almost katakana “ko”. The base 73 has a key shape along the corner of the cover 31 of the back cabinet 3 when viewed from the display surface 1a side, and is substantially at the center of the surface facing the bottom surface of the key cover 31. The holding part 71 is formed so that one end of the holding part 71 rises substantially vertically, and the surface facing the side surface of the cover part 31 of the key-shaped part and the surface on the other end side of the holding part 71 are substantially parallel to each other. Is done.

  Then, by holding the reflection surface 213 and the transmission surface 211 by the holding portion 71 and supporting a part of the outer periphery of the paraboloid 212 by the corner portion 73a along the corner of the cover portion 31 of the base portion 73, The rear side portion of the front cabinet 2 as viewed from the display surface 1 a side is held by the holding portion 71 and the corner portion 73 a of the base portion 73. In this state, the front cabinet 2 and the back cabinet 3 are fixed by screwing the base portion 73 to the back surface of the back cabinet 3. As a result, the front cabinet 2 and the back cabinet 3 are fixed. These are fixed by sandwiching the panel module 1.

  In addition, since the attachment member 7 is disposed along the transmission surface 211, light corresponding to the region covered by the attachment member 7 of the transmission surface 211 is not incident, and there is a region where no background image is displayed on the front cabinet 2. Will exist. Therefore, the attachment member 7 is disposed at a position that does not give the viewer as much discomfort as possible even when there is a region where a background image is displayed such as the four corners of the front cabinet 2. Moreover, the width of the attachment member 7 is made as short as possible, and the region where the transmission surface 211 is covered by the attachment member 7 is formed as small as possible.

In addition, a sealing member such as rubber is interposed between the corner portion 73a of the base portion 73 along the corner of the cover portion 31 and the parabolic surface 212, so that the mounting member and the front cabinet 2 are more securely fixed. It may be.
Also in this case, as shown in FIG. 7, since a gap is formed between the front cabinet 2 and the end of the panel module 1 on the display surface 1a side, for example, a frame-shaped buffer member is interposed in this gap. By doing so, the front cabinet 2 and the panel module 1 may be more securely fixed, and foreign matter such as dust may be prevented from entering the interior.
Also in this case, the front cabinet 2 is divided into a plurality of members, and each member divided by the front cabinet 2 is attached to the panel module 1 and the back cabinet 3 and the plurality of members are fixed to each other. It is fixed by that.

Next, the operation of the second embodiment will be described.
The front cabinet 2 is composed of the optical member 300 as described above, and is an area that overlaps the transmission surface 215 when viewed from the front side of the liquid crystal television 100 from the transmission surface 215 that is the front surface of the front cabinet 2. The light of the back part of is emitted. Accordingly, also in the second embodiment, as shown in FIG. 4A, the front cabinet 2 actually exists, but from the observer, the background of the front cabinet 2 is present in the frame-like region 100a. As shown in FIG. 4B, the frame-like member 100a appears as if it is displayed, and only the display area 11a is visible. Therefore, since the frame region does not exist visually, it is possible to avoid giving the viewer a sense of incongruity.

Further, since the optical member 300 is formed by using a parabolic mirror, it can be formed with a smaller number of end faces compared to the case of using only a reflective surface, and is realized with a relatively simple shape. be able to.
In addition, since the reflection surface 213 and the paraboloid surfaces 212 and 214 are provided with a reflection film on the outer periphery so as to be totally reflected, it is possible to prevent a reduction in the amount of light upon reflection on these surfaces. The background image that can be seen can be a clear background image.

Further, since the back light is transmitted only by reflection, chromatic aberration does not occur, and the background image visible to the observer can be a clear background image.
Also in this second embodiment, an optical path length difference is generated, so that in this case as well, a relay lens may be arranged as in the first embodiment, and it is equivalent to the relay lens. In addition, the optical path length difference may be absorbed by correcting the paraboloid.
Here, a region overlapping the region W11 of the transmission surface 211 corresponds to the incident surface, and a region overlapping the region W11 of the transmission surface 215 corresponds to the emission surface. The paraboloid 212 corresponds to the first paraboloid mirror, the paraboloid 214 corresponds to the second paraboloid mirror, and the reflection surface 213 corresponds to one reflection surface.

Next, a third embodiment of the present invention will be described.
Since the third embodiment is the same as the second embodiment except that the shape of the optical member constituting the front cabinet 2 is different, the same reference numerals are given to the same parts, and the detailed description thereof is omitted. Description is omitted.
FIG. 8 is a diagram showing a configuration of the front cabinet 2 in the third embodiment. It is a horizontal sectional view showing the left frame part which constitutes front cabinet 2 seeing from the front side.

As shown in FIG. 8, the front cabinet 2 in the third embodiment has a bottom surface as a recess for housing the end portions of the panel module 1 and the back cabinet 3 in the front cabinet 2 in the second embodiment. It has a recess 301.
The panel module 1 and the back cabinet 3 are schematically represented as the panel module 1 in FIG. Further, FIG. 8 schematically shows the non-display area 11b and the flange portion 12 of the panel module 1 as the non-display area 11b.

Moreover, in description of FIG. 8, it demonstrates as the positional relationship seen from the display surface 1a side of the panel module 1. FIG.
The optical member 400 is formed symmetrically with respect to the display surface 1a side and the back surface side of the panel module 1 when viewed from the display surface 1a side.
As shown in FIG. 8, the recess 301 includes a bottom surface 301 a and side surfaces 301 b and 301 c that form paraboloids and are parabolic surfaces.

As shown in FIG. 8, the optical member 400 includes an incident-side transmission surface 311, an incident-side paraboloid 312, a reflection surface 313, an emission-side transmission surface 314, and an emission-side paraboloid 315. . Reflective films such as aluminum foil are attached to the outer periphery of the paraboloid surfaces 312 and 315 and the reflective surface 313 to form a parabolic mirror and a plane mirror, respectively.
When the panel module 1 is accommodated in the recess 301, the transmission surface 311 is positioned behind the panel module 1 when viewed from the display surface 1a side of the panel module 1, and receives light (background) on the back of the panel module 1. . The transmission surface 311 receives the reflected light of the paraboloid 312 and reflects the reflected light incident at an angle larger than the critical angle toward the reflection surface 313. That is, the transmissive surface 311 functions as a transmissive surface and also as a reflective surface.

  The paraboloid 312 forms one side surface 301a of the depression 301, and the focal point thereof is located on a reflection surface 313 to be described later. The paraboloid 312 is disposed at a position where the incident angle of the reflected light of the paraboloid 312 that is incident on the transmission surface 311 is larger than the critical angle of the transmission surface 311. The paraboloid 312 receives incident light transmitted through the transmission surface 311 and reflects the incident light toward the direction of the transmission surface 311 closer to the reflection surface 313.

The paraboloid 312 has a width that overlaps the non-display area 11b of the panel module 1 when viewed from the display surface 1a side when the panel module 1 is accommodated in the depression 301, and the display area of the reflection surface 312. The end portion on the 11a side is arranged at a boundary position between the non-display area 11b and the display area 11a or a position slightly closer to the display area 11a than the boundary position.
That is, as will be described later, the background image that is displayed by the back light being detoured by the optical member 400 and emitted from the front side and the display image of the display area 11a are displayed in the display area 11a and the non-display area 11b. The background image is arranged so as to be partially overlapped with the display region 11a, and at this time, the viewer sees the background image superimposed on the display region 11a. It arrange | positions so that it may overlap so that it may not interfere with the display image of the area | region 11a.

The reflection surface 313 is arranged perpendicular to the transmission surface 311 at the position of the focal point X of the reflected light of the paraboloid 312 reflected by the transmission surface 311. The reflection surface 313 reflects the reflected light of the transmission surface 311 toward the transmission surface 314.
The transmission surface 314 is arranged in parallel with the transmission surface 311 in a line-symmetric relationship with the transmission surface 311 about a straight line passing through the focal point X and parallel to the transmission surface 311. The transmission surface 314 vertically enters the transmitted light that has passed through the transmission surface 311, transmits the light as it is, and reflects the reflected light from the reflection surface 313 toward the paraboloid 315. Since the transmission surface 311 and the transmission surface 314 are in a line-symmetric relationship, the reflected light of the reflection surface 313 incident on the transmission surface 314 is incident at an angle larger than the critical angle of the transmission surface 314. Total reflection is performed at 314. The transmission surface 314 transmits the reflected light composed of parallel light incident from the paraboloid 315 as it is and transmits it. That is, the transmission surface 314 functions as a reflection surface that totally reflects the reflected light of the reflection surface 313 and also functions as a transmission surface that transmits the transmission light of the transmission surface 311 and the reflection light of the paraboloid 315.

The paraboloid 315 forms the other side surface 301c of the depression 301 and is in a line-symmetric relationship with the paraboloid 312 about the same axis as the axis of line symmetry of the transmission surfaces 311 and 314. The paraboloid 315 converts the reflected light of the transmission surface 314 into parallel light and reflects it toward the transmission surface 314. Since the paraboloid 312 and the paraboloid 315 are in a line-symmetric relationship, the reflected light composed of parallel light reflected by the paraboloid 315 enters the transmission surface 314 perpendicularly.
In addition, the paraboloid 315 has the same width as the paraboloid 312, and the end on the display area 11 a side thereof is disposed at a position overlapping the end on the display area 11 a side of the paraboloid 312.

  For this reason, as shown in FIG. 8, in the transmission surface 314, the background image of the background overlapping the region W21 is reflected on the reflection surface 314 in the region W21 overlapping the paraboloid surfaces 312 and 315 when viewed from the display surface 1a side. In the region W22 of the reflective surface 314 that does not overlap with the paraboloids 312 and 315, the background that overlaps the region W22 is transmitted through the transmission surface 311 and appears as a background image on the reflection surface 314 as it is. It will be. Therefore, the background image of the area overlapping the reflective surface 314 as viewed from the display surface 1a side is displayed on the reflective surface 314.

Therefore, in this case as well, an action equivalent to that of the second embodiment can be obtained, and in the third embodiment, an interval is provided between the paraboloids 312 and 315. Accordingly, the width and depth of the frame of the front cabinet 2 can be reduced when viewed from the display surface 1a side.
Also in this case, the reflection surface 313 and the paraboloid surfaces 312 and 315 are provided with a reflection film so as to be totally reflected, and the transmission surface 311 and the transmission surface 314 that act as the transmission surface and the reflection surface are also incident. Since the reflected light is totally reflected, the amount of light does not decrease at the time of reflection, and the background image visible to the observer can be a clear background image.
Here, a region overlapping the region W21 of the transmission surface 311 corresponds to the incident surface, a region overlapping the region W21 of the transmission surface 314 corresponds to the emission surface, and the paraboloid 312 corresponds to the first parabolic mirror. The parabolic surface 314 corresponds to the second parabolic mirror, and the reflective surface 313 corresponds to one reflective surface. Further, the transmission surface 311 corresponds to the first transmission surface, and the transmission surface 314 corresponds to the second transmission surface.

  As in the third embodiment, the present invention is not limited to the case where the reflected light from the paraboloid 312 is reflected once and transmitted to the focal point X. For example, as shown in FIG. The reflected light of the paraboloid (first paraboloid mirror) 312 may be reflected twice and transmitted to the focal point X. That is, a projecting surface (one reflection) that is disposed between the paraboloid 312 and the paraboloid (second parabolic mirror) 315 so as to project on the side facing the panel module 1 and parallel to the reflecting surface 313. Surface) 411, and a reflective film such as an aluminum foil is attached to the outer periphery of the projecting surface 411 to form a plane mirror. Further, in the reflection surface (first reflection surface, second reflection surface) 313, the reflected light of the transmission surface (first transmission surface) 311 is further reflected toward the projection surface 411, and the projection surface 411 is reflected on the projection surface 411. The focal point X of the paraboloid 312 reflected by the transmission surface 311 and the reflection surface 313 is disposed.

  The transmissive surface 311 and the transmissive surface (second transmissive surface) 314, and the paraboloid 312 and the paraboloid 315 are in a line-symmetric relationship about a straight line passing through the focal point X and parallel to the transmissive surface 311. The light transmitted through the transmissive surface 311 is reflected by the paraboloid 312, totally reflected by the transmissive surface 311 and the reflective surface 313, the focal point X is formed on the projecting surface 411, and reflected by the projecting surface 411. The reflected light that diverges from the focal point X is reflected by the reflecting surface 313 and the transmitting surface 314 and transmitted to the paraboloid 315 where it is converted into parallel light and incident perpendicularly on the transmitting surface 314. Transmitted and emitted. In addition, in a region that does not overlap with the paraboloid 312 when viewed from the transmission surface 314 side, the light incident on the transmission surface 311 is emitted from the transmission surface 314 as it is. Accordingly, the background image of the region overlapping the transmission surface 314 when viewed from the display surface 1a side is displayed on the transmission surface 314.

Therefore, in this case as well, it is possible to obtain the same effect as the third embodiment, and since the number of reflections is increased and the optical path is bent, the width of the frame of the front cabinet 2 can be narrowed accordingly. it can.
Further, for example, the surface 411 on which the focal point X is located is not projected as shown in FIG. 9A, and the surface 411 is arranged between the end portions of the paraboloids 312 and 315 as shown in FIG. 9B. In this case as well, the width of the frame of the front cabinet 2 can be reduced.

Also in the case of the third embodiment, since the light at the back of the front cabinet 2 is transmitted only by reflection, a background image that can be seen by an observer without causing chromatic aberration is defined as a clear background image. can do.
Also in this third embodiment, an optical path length difference occurs, but in this case as well, an optical path length difference may be absorbed by disposing a relay lens as in the first embodiment. Alternatively, the optical path length difference may be absorbed by correcting the paraboloid so as to be equivalent to the relay lens.

  In each of the above embodiments, the case where the surface acting as the reflecting surface is totally reflected has been described. However, the reflected light is light corresponding to the background and does not necessarily have to be clear. , It does not have to be totally reflected. For example, when the background of the liquid crystal television 100 has a characteristic pattern or the like, the background image displayed on the front cabinet 2 may be uncomfortable if the background image is not clear. However, it does not give the viewer a sense of incongruity even if the background image is not clear. Therefore, it may be determined whether or not the total reflection is performed according to the background of the place where the liquid crystal television 100 is installed.

In each of the above embodiments, the case where the present invention is applied to the liquid crystal television 100 has been described. However, the present invention is not limited to this, and the present invention can also be applied to a liquid crystal display device such as a personal computer. Any flat panel display such as an EL display can be applied.
In each of the above embodiments, the case where the front cabinet 2 itself is formed of an optical member has been described. However, the present invention is not limited to this, and the front cabinet 2 and the optical member may be formed separately. That is, in the liquid crystal television itself in which the panel module is fixed by the front cabinet, the back, and the cabinet, the above-mentioned optical member is formed in a size that covers the non-display area from the end face and sandwiches the front and rear sides. You may make it attach an optical member along the outer diameter of a liquid crystal television. Moreover, you may make it comprise an optical member so that removal is possible.

  In each of the above-described embodiments, the optical members are arranged on all four sides of the liquid crystal television, and all the four sides around the display area 11a are shown as if they do not exist. Instead, for example, it may be provided on only two sides or only three sides. In this case, even if only one of the four sides, such as the three sides excluding the lower side, or the two left and right sides, is present, it does not give the viewer a sense of incongruity. What is necessary is just to arrange. Further, for example, a region where a speaker, an input / output terminal, and the like are arranged may be cut out so that only the region excluding the speaker and the input / output terminal portion is invisible to the observer.

It is the schematic perspective view which decomposed | disassembled the liquid crystal television to which this invention is applied.
