  In the above-mentioned narrowing of the frame, the emphasis has been on narrowing the frame on the side and the upper side of the display panel. However, the applicant has now considered reducing the frame on the lower side. However, a remote control sensor is usually arranged in the lower frame (Patent Document 6). Therefore, if the frame is simply narrowed, the remote control sensor cannot be arranged.

  The display device of the present invention includes a display panel, a resin frame surrounding four sides of the front peripheral portion of the display panel, a metal frame provided on the lower side of the resin frame, and a conductive frame provided on the back side of the metal frame. The metal frame includes a piece inclined backward with respect to the resin frame and an opening for allowing light to enter the light guide member, and the opening is provided in the piece inclined backward. It is characterized by that.

  According to the present invention, it is possible to realize a narrow frame on the lower side of the display panel while securing the arrangement of the remote control sensor.

(Overall structure of display device 10)
FIG. 1 is a front perspective view of the display device 10. The display device 10 includes a display panel 1, a front frame 2 that covers a peripheral portion (non-display area of the display panel 1) and a side surface of the display panel 1, and a stand 3 that supports the display panel 1 from the back. (In FIG. 1, the base 31 is displayed in the stand 3). The display panel 1 is a plasma display panel in this embodiment. The front frame 2 includes a resin frame 2a and metal frames 2b and 2c.

  FIG. 2 is a rear view of the resin frame 2a. That is, the side hidden in FIG. 2 is the surface side of the display device 10 and is the side visible to the viewer. The resin frame 2a is a frame-shaped resin member having four sides, and covers the four side surfaces of the display panel 1 and the image non-display portion outside the front surface of the display panel 1 (see FIG. 1). That is, the resin frame 2 a functions as an outer frame of the display panel 1. FIG. 2 is a rear view of the resin frame 2a, and the rear surface 21 of the resin frame 2a is shown in FIG.

  FIG. 3 is a perspective view of the metal frame 2b. The metal frame 2b is a substantially L-shaped rod-like member, and is mounted on the upper side of the resin frame 2a (see FIG. 1). The metal frame 2b includes a piece 22 that comes into contact with the back surface 21 of the resin frame 2a, and a piece 23 that is located above the upper side of the resin frame 2a. A plurality of convex portions 210 are provided on the upper side of the rear surface 21 of the resin frame 2a (see FIG. 2), and a plurality of convex portions 210 are provided on the piece 22 of the metal frame 2b so as to correspond to these convex portions 210. An opening 220 is provided. Then, the metal frame 2b can be fitted into the resin frame 2a by fitting each opening 220 into each projection 210. Note that the surface of the piece 22 that is actually displayed in FIG. 3 is in contact with the back surface 21 of the resin frame 2a.

FIG. 4 is a perspective view of the metal frame 2c. The metal frame 2c is also a substantially L-shaped rod-shaped member. The metal frame 2c is arranged on the lower side of the resin frame 2a (see FIG. 1), and comes from a piece 24 that comes into contact with the back surface 21 of the resin frame 2a and a piece 25 that is located below the lower side of the resin frame 2a. Become. A plurality of convex portions 211 are also provided on the lower side of the back surface 21 of the resin frame 2a (see FIG. 2), and a plurality of openings are formed in the piece 24 of the metal frame 2b so as to correspond to these convex portions 211. 240 is provided. Thereby, the metal frame 2c can be fitted into the resin frame 2a. The piece 25 of the metal frame 2c is provided with openings 250 (openings 251, 252, and 253) corresponding to light guide plates 41, 42, and 43 of the light guide component 40 described later. Note that the surface of the piece 24 that is actually displayed in FIG. 4 is in contact with the surface 21 of the resin frame 2a. Further, the piece 25 is inclined with respect to the piece 24 (see FIG. 7), and when the metal frame 2c is attached, the front surface of the piece 25 faces obliquely downward.

  FIG. 5 is a side view of the display device 10. It is the figure seen especially from the right side surface side. A back cover 5 that covers the display panel 1 is attached to the rear side of the television. The main body (display panel 1 and the like) of the display device 10 is supported by the stand 3. The stand 3 includes a base 3a, a column 3b, a pedestal 3c, and a mounting portion 3d. Among these, the attachment portion 3d is in contact with the back surface of the back cover 5 although it is hidden in FIG. A screw hole for fixing the stand 3 to the display panel 1 is provided in the mounting portion 3d. Corresponding to these screw holes, screw holes are also provided in the back cover 5, and female screws are provided on the back surface of the display panel 1, whereby the stand 3 is fixed to the display panel 1.

  FIG. 6 is an enlarged view of a part of FIG. 1, in particular, an enlarged view of the metal frame 2 c at a portion where the light guide component 40 is attached. Although details of the configuration of the light guide component 40 will be described later, the light guide component 40 includes light guide plates 41, 42, and 43 as shown in FIG. The light guide plate 41 receives infrared light from a remote controller and guides it to a light receiving sensor 47 (described later). The light guide plate 42 receives external light (environment light) and guides it to an illuminance sensor 48 (described later). The light guide plate 43 is for emitting light emitted from an LED 49 (described later) to the outside.

  As shown in FIG. 6, the light guide plates 41 and 42 have their tip portions (light incident surfaces) protruding from the piece 25 of the metal frame 2c. The light incident surface is parallel to the display surface of the display panel 1 or the front surface of the resin frame 2 a, and the light guide plate 41 is caused by the fact that the piece 25 is inclined with respect to the display surface of the display panel 1. , 42 is projected.

  On the other hand, the light guide plate 43 does not protrude from the metal frame 2c at the tip end (light emission surface), and is parallel to the front surface of the piece 25 of the metal frame 2c.

  FIG. 7 is a side sectional view of the display device 10. This figure is a view taken along the plane including the light guide plate 41 for the remote controller, and the left side is displayed as the front surface and the right side as the back surface. Remote control infrared light from the front surface is incident from the front surface of the light guide plate 41 and guided to the right inclined surface 41a (note that infrared light incident from an oblique direction is guided from the lower surface, upper surface, or side surface of the light guide plate 41. Some of them are emitted out of the optical plate 41 and are not guided to the inclined surface 41a). The inclined surface 41a is inclined approximately 45 degrees with respect to the display surface of the display panel 1. The inclined surface 41a is mirror-finished, and part of the infrared light guided to the inclined surface 41a is reflected by the inclined surface 41a. However, not all light is reflected, and part of the light is emitted from the inclined surface 41a to the outside of the light guide plate 41. An inclined surface 91a of the case 9 that accommodates the light guide component 40 is disposed just outside the inclined surface 41a (see FIG. 9 for an overall view of the case 9). The case 9 is made of a black resin, and a convex portion 91 is molded so as to match the shape of the light guide plate 41. The inclined surface 91a is mirror-finished. Therefore, the light emitted from the inclined surface 41a is reflected upward by the inclined surface 91a, and is incident on the light guide plate 41 again from the inclined surface 41a. The light re-entering the light guide plate 41 is emitted from the upper surface of the light guide plate 41 to the outside of the light guide plate 41 again. In the light guide plate 41, instead of depositing a reflective film on the inclined surface 41 a, mirror processing is performed to reduce the cost. However, since the reflectance cannot be ensured as compared with the case of depositing a reflective film, the inclined surface 91a of the case 91 facing the inclined surface 41a is also used. As a result, both cost reduction and light utilization efficiency are achieved.

A light receiving sensor 47 is disposed above the light guide plate 41. The light receiving sensor 47 is provided on the lower surface of the substrate 46 and has a specification that is particularly sensitive to infrared light. The light re-emitted from the light guide plate 41 enters the light receiving sensor 47. As described above, infrared light from the remote controller is guided to the light receiving sensor 47. In particular, since the light receiving sensor 47 is disposed at the rearmost part of the upper surface of the light guide plate 41 (near the boundary between the upper surface of the light guide plate 41 and the inclined surface 41a), the angle of the inclined surface 41a of the light guide plate 41 is determined by the infrared rays from the remote controller. It is designed to efficiently enter the light receiving sensor 47.

  Conventionally, it is difficult to narrow the lower frame of the display panel (narrow the frame of the lower frame) due to the necessity of arranging a substrate for the light receiving sensor. However, in the present embodiment, the light receiving sensor 47 that once receives the infrared light from the remote controller by the light guide plate 41 and converts it into a current is arranged at the back position. Therefore, the metal frame 2c only needs to have a width corresponding to the incident surface of the light guide plate 41, and the lower frame can be narrowed. Further, the piece 25 of the metal frame 2c is inclined rearward so that the lower side is the back. As a result, the metal frame 2c becomes inconspicuous, and thus appears to be narrower (thinner) than the actual width of the metal frame 2c. Therefore, it also has a visual effect that it seems that further narrowing of the frame is realized.

  The light incident surface of the light guide plate 41 is not parallel to the front surface of the piece 25 of the metal frame 2c, but is parallel to the display surface of the display panel 1. This is because, if the incident surface is parallel to the display surface of the display panel 1, it is natural that infrared light from the remote controller can be received with high sensitivity. As a result, the incident surface of the light guide plate 41 protrudes from the opening 251 of the metal frame 2c. However, the light incident surface of the light guide plate 41 is a transparent resin material, and the metal frame 2c is silver. Therefore, even if the light incident surface of the light guide plate 41 protrudes, it does not stand out so much, and it is considered that there is no particular problem even on the design surface (in terms of appearance design).

  In addition, the light path of the infrared light is bent using the light guide plate 41 and the inclined surface of the case 9, and the light receiving surface of the light receiving sensor 47 faces downward. Thereby, the board | substrate 46 for arrange | positioning the light reception sensor 47 grade | etc., Can be arrange | positioned perpendicularly | vertically with respect to the display surface of the display panel 1. FIG. Therefore, even if the area of the substrate 46 is slightly increased, there is no problem in narrowing the frame of the lower frame of the display panel 1.

  Furthermore, in the present embodiment, a resin film is not provided on the inclined surface 41a of the light guide plate 41, or the mirror surface of the inclined surface 41a is mirror-finished. A recess is provided in 9 and the recess is mirror-finished. Thereby, cost reduction is realized.

  FIG. 8 is a perspective view of the light guide component 40. The light guide component 40 includes a light guide plate 41 that guides light to the light receiving sensor 47, a light guide plate 42 that guides light to the illuminance sensor, and a light guide plate 43 that guides light from the LEDs to the outside. The light guide component 40 shown in FIG. 8 is made of a transparent resin and is integrally formed.

  The illuminance sensor is for detecting the illuminance of the external light of the display device 10, and is arranged so as to face the illuminance sensor installation part 48 of FIG. The display device 10 detects the brightness of the installation location (room) based on the amount of light detected by the illuminance sensor, and controls the brightness of the image displayed on the display panel 1 based on the detected brightness. . For example, when a room is dark, control is performed so that an image with reduced brightness is displayed. External light first enters the light guide plate 42 and is guided to the illuminance sensor. In order to detect external light with high sensitivity, the light incident surface of the light guide plate 42 is parallel to the display surface of the display panel 1 and protrudes from the piece 25 of the metal frame 2c, like the light incident surface of the light guide plate 41. Deployed.

An LED installation unit 49 is arranged on the right side of the illuminance sensor installation unit 48. This LED is used to indicate the on / off state of the power supply as seen in a normal television device. The LED is arranged so as to face the LED installation portion 49, and the light from the LED is guided by the light guide plate 4.
3 is emitted to the outside of the display device 10. The light exit surface of the light guide plate 43 is parallel to the front surface of the piece 25 of the metal frame 2 c and does not protrude from the piece 25. This is because the light of the LED is colored (red, blue, or green), and is conspicuous if it is configured to project like the light guide plates 41 and 42, so that it is considered that it is not preferable in terms of appearance design. On the other hand, even if the light exit surface faces obliquely downward, the LED light is colored, so that the viewer of the display device 10 can fully see the LED light, and it is considered that there is no particular problem.

  An opening 45 is provided behind the light guide plate 41. The convex portion 91 of the above-described case is inserted into the opening 45. The light receiving sensor 47 is provided at a position above the opening 45. The light guide plates 41, 42 and 43 are connected by a glass member 46b. However, in order to prevent light from propagating between the light guide plates 41 and 42, an opening 45 is provided behind the light guide plate 41, and the light guide plate 41 and the glass member 46b are connected by a leg-like member. The area of the connecting part is reduced. Further, in order to prevent light from propagating between the light guide plates 41 and 42, openings 47a, 47b and 47c are provided, and the protrusions of the black resin case 9 are inserted into the openings 47c. This prevents light from the LED from entering the illuminance sensor.

  FIG. 9 is a perspective view of the case 9 that accommodates the light guide component 40. FIG. 9 shows a state in which the light guide component 40 is already accommodated. Further, this figure shows a state in which the cover 44 is mounted on the upper side of the light guide component 40 shown in FIG. On the upper side of the cover 44 is a connector 45, through which signals received by the light receiving sensor 47 and the illuminance sensor are mounted via a so-called main board (circuits for processing broadcast signals and images). Board).

  Next, a structure for attaching the case 9 to the main body of the display device 10 will be described. FIG. 10 is a perspective view of the metal reinforcing frame 6 for attaching the case 9, and shows a state where the case 9 is not attached. FIG. 11 is a perspective view of the reinforcing frame 6 with the case 9 attached. The reinforcing frame 6 is used to reinforce the load applied to the lower side of the display panel 1, and is fixed to the lower side of the chassis 1c (see FIG. 12) on the back surface of the display panel 1 with screws or the like.

  The reinforcing frame 6 is for preventing damage when the display panel 1 is dropped. Since the display panel 1 is supported by the stand 3 as described above, the display panel 1 will not fall as long as it is used normally. However, the display panel 1 may fall for some reason. In this case, if the display panel 1 is easily damaged, the user is disadvantaged. Therefore, in view of (1) that the lower side is likely to be subjected to weighting of the display panel 1 and (2) that the lower side of the display panel 1 is normally used with the lower side down, the display panel 1 is susceptible to being dropped. The reinforcing frame 6 is provided on the lower side of the frame. Note that reinforcing frames may also be provided on the left and right sides of the display panel 1. This reinforcing frame may have a simpler configuration than the reinforcing frame 6.

  FIG. 13 is an enlarged view of a part of FIG. 10 and is an enlarged view of a portion of the reinforcing frame 6 to which the case 9 is attached. A pair of female screws (tapped screw holes) 62 a and 62 b are provided in the concave portion of the reinforcing frame 6. By screwing these female screws with the positions of the screw holes 92a, 92b (see FIG. 9) of the case 9 being aligned, the case 9 can be screwed to the reinforcing frame 6 as shown in FIG. it can. A plurality of screw holes 63 on the upper side of the female screw 62 are used for screwing the reinforcing frame 6 to the chassis 1c.

Again, referring to FIG. 7, configurations other than the light guide component 40 and the case 9 will be described. The display panel 1 (in this embodiment, a plasma display panel) includes a front panel 1a, a back panel 1b, and a chassis 1c. Among these, red, blue, and green phosphors that actually emit light are arranged for each pixel on the rear panel 1b, and these phosphors emit light in accordance with video signals, whereby an image is displayed on the display panel 1. Is displayed. A drive circuit 31 (so-called panel driver) for driving the display panel 1 is provided on the back side of the display panel 1. The control signal generated by the drive circuit 31 is transmitted to the rear panel 1b via the flexible board 32.

  Thus, in this embodiment, the light guide component 40 including the light guide plate 41, the light receiving sensor 47, and the like is housed in the case 9. Therefore, even if the shape of the frame or the like is changed in accordance with the design change of the display device, it is possible to cope with the case unit, so it is not necessary to change the light receiving optical system itself, and the design change can be easily handled. .

(Cover structure of metal frame 2b)
As a front frame for supporting a display panel of a television apparatus, a metal or resin frame has been conventionally used. Here, when the front frame is made of resin, there are advantages that the material cost is low and the cost can be reduced and the weight can be reduced. On the other hand, in the case of resin, there is a disadvantage that it lacks a high-class feeling and is inferior in design as compared with a metal frame. In view of this, there are many television apparatuses that employ a configuration in which the four side surfaces of the display panel are first surrounded by a resin frame, and further, the resin frame is decoratively covered with a metal frame. In other words, resin is used for the frame that directly supports the display panel and requires a relatively large volume, and the metal is used decoratively to reduce the volume of the metal frame and reduce the overall material cost. At the same time, it ensures design.

  However, in recent years, competition for further cost reduction of televisions has progressed. The applicant has conducted various studies in order to reduce costs. As a result, the cost of the metal frame was also reduced. That is, conventionally, the metal frame has been configured to surround the four sides of the resin frame, but this time, the metal frame is provided only on the upper and lower sides of the resin frame. Thereby, the material cost of the metal frame can be greatly reduced. In particular, when the size of the display panel is large (for example, 50 inches or more), the cost reduction effect is large. Also, if the upper and lower sides that are visually conspicuous are made of metal, the left and right sides that are visually inconspicuous are made of resin, and the design is not inferior.

  However, a new problem occurs in the configuration in which the metal frame is provided only on the upper side and the lower side. This is because the left and right ends of the metal frame are exposed. Since the thickness of the metal frame 2b is about several millimeters, for example, when the display device 10 is transported, touching the tip of the metal frame 2b with a finger may injure the finger. Therefore, as described below, the display device 10 employs a configuration in which the tip portion of the metal frame 2b is covered with a cap 4 made of resin.

  FIG. 15 is a rear view of the metal frame 2b, particularly an enlarged view of the tip portion. FIG. 16 is a perspective view of the tip portion of the metal frame 2b. FIG. 17 is a perspective view of the cap 4.

First, with reference to FIG. 16, the structure of the front-end | tip part of the metal frame 2b is demonstrated. A substantially T-shaped opening 221 is provided at the tip of the piece 22 of the metal frame 2b. The opening 221 includes an opening 221a positioned on the side away from the tip corresponding to the T-shaped horizontal bar portion, and an opening 221b positioned on the side close to the tip corresponding to the T-shaped vertical bar portion. Further, a groove 223 is provided on the back side (as shown in FIG. 16) of the piece 22. The groove 223 is provided in such a manner as to scrape both ends on the back side of the opening 221b, and the thickness of the piece 22 is approximately half that of other portions in the portion where the groove 223 exists. Yes. A groove 222 is provided at the boundary between the piece 22 and the piece 23. This groove extends along the horizontal direction of the metal frame 2b. The piece 23 is further divided into a piece 231 inclined with respect to the piece 22 and a piece 232 further inclined with respect to the piece 231 and perpendicular to the piece 22. A groove 233 is formed inside the pieces 231 and 232. When the metal frame 2b is attached to the main body of the display device 10, the piece 23 comes above the piece 22.

  Next, the structure of the cap 4 will be described with reference to FIG. The cap 4 includes a first arm part 41, a second arm part 42, a third arm part 43, a shoulder part 44, and a cover part 45. The cover portion 45 is made of resin, but the first arm portion 41, the second arm portion 42, the third arm portion 43, and the shoulder portion 44 are made of metal.

  The 1st arm part 41 is a part engaged with the groove | channel 233 of the metal frame 2b. The 2nd arm part 42 is a part engaged with the opening 221 of the metal frame 2b. Further, the second arm portion 42 includes a T-shaped member 421 and a flat plate-like member 422 provided on the back surface thereof. The shoulder portion 44 is a portion that connects the first arm portion 41, the second arm portion 42, and the third arm portion 43. The cover part 45 is in contact with the shoulder part 44.

  Next, a procedure for attaching the cap 4 to the tip portion of the metal frame 2b will be described. First, the cap 4 is positioned so that the second arm portion 42 of the cap 4 comes to the lower side (back side) of the opening 221 of the metal frame 2b. At this time, care is taken that the tip of the first arm portion 41 comes to the tip of the groove 233 of the metal frame 2b.

  In this state, the second arm portion 42 of the cap 4 is slid within the opening 221b of the opening 221. During this time, the first arm portion 41 also slides in the groove 222. When the tip of the second arm portion 42 reaches the opening 221a, the back side of the piece 22 with respect to the second arm portion 42 so that the portion of the T-shaped member 421 of the second arm portion 42 fits into the opening 221. Apply force in the direction of the front side. As a result, the T-shaped member 421 of the second arm portion 42 fits into the opening 221 and the flat plate member 422 fits into the groove 223. On the other hand, the third arm portion 43 is located on the surface 224 side of the piece 22. That is, the first arm portion 41 and the third arm portion of the cap 4 are located on the front surface 224 side of the piece 22, the second arm portion is located on the back surface side of the piece 22, and the piece 22 is sandwiched between the arm portions. The cap 4 is fixed.

  When the cap 4 is attached to the display device 10, the cover portion 45 (or the first arm portion 41) of the cap 4 is positioned above the display device 10, and the third arm portion 43 is below the display device 10. Will be located on the side. That is, since the upper corner portion of the display device 10 is covered with the resin cover 45, even when the display device 10 is transported, it is possible to prevent injuries such as tearing a finger. it can.

  In the above, the attachment structure and method of the cap 4 to the front-end | tip part of the metal frame 2b were demonstrated. The mounting structure and method at the other end of the metal frame 2b are the same. However, since the shape of the tip portion of the metal frame 2b and the shape of the cap are symmetrical with respect to those described above, it is necessary to prepare a cap separately from the cap 4. In addition, the attachment method and structure of the cap with respect to the metal frame 2c located on the lower side of the display panel 1 are substantially the same as described above. However, the shape of the cap attached to the metal frame 2c is slightly different from that of the cap 4 because the shape of the metal frame 2c is slightly different from the shape of the metal frame 2b. However, the main configuration is substantially the same, and the mounting procedure to the metal frame 2c is also substantially the same.

As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to the thing of embodiment shown in figure. Various modifications and variations can be made to the illustrated embodiment within the same range or equivalent range as the present invention.
For example, in the above description, a plasma display has been described as an example of the display device. However, the present invention can be applied to other display devices such as a liquid crystal display.

  The present invention can be applied to an image display device of a liquid crystal television or a plasma television.
