Description

  The present invention relates to a display device for displaying video and a television receiver.

  Thin display devices, such as liquid crystal display devices, that occupy a smaller area than the size of a display screen, for example, liquid crystal display devices, are widely used because they can effectively use a limited indoor space. The liquid crystal display device has a rectangular frame-shaped cabinet, and houses a display panel and a light source for displaying an image in the cabinet.

  The light source emits heat together with light emission, but the control circuit for controlling the driving of the display panel, the processing circuit for processing the image, and the like may malfunction due to the heat generated in the cabinet. Therefore, in recent years, a liquid crystal display device in which a cabinet is made of metal has been proposed in order to efficiently release heat.

  The cabinet is assembled by, for example, extruding a metal member to produce a plurality of frame-shaped members having a bowl shape, and connecting the frame-shaped members with a connector. Manufacturing by extrusion molding can reduce manufacturing costs compared to manufacturing by press molding or cutting using a mold. In addition, it is possible to easily and flexibly cope with design changes according to the dimensions of the display screen (dimensions of the portion where the video is displayed).

  Conventionally, the color of the light source used for the display panel has been three colors (red, green and blue), but recently, a display panel using four colors (red, green, blue and yellow) has been proposed. The three-color display panel and the four-color display panel have different external dimensions of the display panel even when the dimensions of the display screen are the same. Therefore, the connector is designed in accordance with the dimensions of each display panel so that the dimensions of the entire liquid crystal display device are the same, and the dimensions of the connector related to the three-color display panel and the four-color display panel are related. It differs from the dimensions of the coupler.

  On the other hand, the frame structural member according to the three-color display panel and the frame structural member according to the four-color display panel have substantially the same dimensions. Therefore, an operator may mistakenly connect the frame constituent members related to the three-color display panel by the connecting tool related to the four-color display panel or vice versa. In this case, it is necessary to disassemble and reassemble the liquid crystal display device, resulting in a decrease in manufacturing efficiency.

  Patent Document 1 discloses an invention in which a male connector and a female connector are each provided with a concave portion and a convex portion corresponding to the concave portion in order to prevent erroneous insertion. It is also conceivable to prevent erroneous insertion by providing the frame constituent member and the connector with the same configuration as the concave portion and the convex portion.

In another display device, the inclined surface or the notch is provided. Incorrect insertion is prevented by using a frame component not to be used and a connector corresponding to the frame component.

  In the display device according to the present invention, a screw hole is provided in the frame constituent member, and an insertion hole through which a screw is inserted at a position corresponding to the screw hole is provided in the connector. The bottom surface of the concave portion is disposed at a position separated from the insertion hole along the insertion direction.

  In the present invention, since the bottom surface of the concave portion is arranged at a position separated by a predetermined distance or more from the insertion hole through which the screw is inserted, when the frame constituent member having no inclined surface or notch is inserted into the concave portion, The frame constituent member cannot be inserted up to the bottom surface of the recess. Generally, a screw hole corresponding to the insertion hole is provided in the frame constituent member, and a screw is inserted into the insertion hole of the connector and is screwed into the screw hole to connect the two. When the frame constituent member cannot be inserted to the bottom surface of the recess, the insertion hole and the screw hole are not aligned, and the operator cannot connect the two. Therefore, the operator can easily recognize erroneous insertion of the frame component member into the connector.

  In the display device according to the present invention, a distance between the insertion hole and the bottom surface is longer than a distance set when an end surface of the frame constituent member is flat.

Thus, the display device 100 is manufactured.

  Next, as a comparative example of the television receiver according to the first embodiment, a configuration of a television receiver equipped with a display panel 10 of three colors (red, green, and blue) will be described. 7 is an exploded perspective view of a part of the television receiver as seen from the back side, FIG. 8 is a perspective view showing a state where the members shown in FIG. 7 are assembled, and FIG. 9 is a perspective view of the television receiver shown in FIG. It is a partial rear view. 7 to 9 show the connection configuration at the lower left corner of the front, and the member arranged at the lower right corner of the front is symmetrical with the member arranged at the lower left corner of the front, and is arranged at the upper right corner of the front. The formed member is bilaterally symmetric with the member disposed at the lower right corner of the front surface.

  Since the outer dimensions of the three-color display panel 10 are slightly smaller than the outer dimensions of the four-color display panel 10, the connector 140 of the television receiver on which the three-color display panel 10 is mounted is described in the first embodiment. It is designed to be larger than the connector 40 of such a television receiver (a television receiver equipped with the four-color display panel 10).

The connector 140 includes a recess 42, and the bottom surface of the recess 42 forms a flat surface 42a that is substantially parallel to the left-right direction. Further, the lower end surface of the ridge 26 corresponding to the recess 42 also forms a flat surface 26a substantially parallel to the left-right direction. When the flat surface 26a comes into contact with the flat surface 42a, the vertical frame constituent member 202 and the connector 140 are positioned in the longitudinal direction of the vertical frame constituent member 202, and the positions of the screw hole 27a and the insertion hole 45a are aligned. . In this state, the connector 47 and the vertical frame component member are secured by screwing the screw 47 into the screw hole 27a of the plate portion 27 through the missing portion 28a of the plate portion 28 and the insertion hole 45a of the protruding piece 45. 202 (see FIG. 9).
As shown in FIGS. 9 and 6, the insertion hole 45a of the television receiver on which the three-color display panel 10 is mounted is flatter than the television receiver according to Embodiment 1 in the vertical direction. Close to the bottom surface of the recess 42. That is, the distance d1 between the center of the insertion hole 45a and the flat surface 42a in the first embodiment is between the center of the insertion hole 45a and the flat surface 42a in the television receiver on which the three-color display panel 10 is mounted. Longer than the distance d2.

  Next, a case where the vertical frame constituent member 202 according to Embodiment 1 is erroneously inserted into the connector 140 will be described. FIG. 10 is a partial rear view of the television receiver showing a state in which the vertical frame constituent member 202 according to Embodiment 1 is erroneously inserted into the connector 140. As shown in FIG. 10, when the operator mistakenly inserts the vertical frame constituent member 202 according to Embodiment 1 into the connector 140, the flat surface 26 a comes into contact with the flat surface 42 a of the connector 140. At this time, the flat surface 26a must be separated from the insertion hole 45a by the distance d1 downward, but is spaced downward from the insertion hole 45a by a distance smaller than the distance d1. For this reason, the positions of the screw hole 27a and the insertion hole 45a are not aligned, and the operator cannot screw the screw 47 into the screw hole 27a, and can easily and reliably recognize erroneous insertion.

  Next, a case where the vertical frame constituent member 202 related to the television receiver on which the three-color display panel 10 is mounted is erroneously inserted into the connector 40 will be described. FIG. 11 is a partial rear view of the television receiver showing a state in which the vertical frame constituent member 202 related to the television receiver on which the three-color display panel 10 is mounted is erroneously inserted into the connector 40 according to the first embodiment. is there. As shown in FIG. 11, when the operator mistakenly inserts the vertical frame constituent member 202 relating to the television receiver on which the display panel 10 of three colors is mounted into the connector 40, the flat surface 26 a is inclined to the connector 40. It abuts on the surface 42b. At this time, the flat surface 26a must be separated from the insertion hole 45a by a distance d2 downward, but is located above the insertion hole 45a. For this reason, the positions of the screw hole 27a and the insertion hole 45a are not aligned, and the operator cannot screw the screw 47 into the screw hole 27a, and can easily and reliably recognize erroneous insertion.

  The television receiver according to the first embodiment can be assembled simply by inserting the end of the frame constituent member 202 into the recess 42 corresponding to the inclined surface 26b, and a large space is required for the assembly of the front cabinet 20. It is not necessary, and thinning and narrowing of the frame can be maintained. Further, in one television receiver, an inclined surface 26b is formed at the end of the frame component member 202, and a recess 42 corresponding to the inclined surface 26b is formed in the connector 40. In another television receiver, the inclined surface 26b is formed. By using the frame constituent member 202 not having the surface 26b and the connector 140 corresponding to the frame constituent member 202, erroneous insertion can be prevented.

  In addition, since the bottom surface of the concave portion 42 is disposed at a position separated by a predetermined distance or more from the insertion hole 45a through which the screw 47 is inserted, when the vertical frame constituent member 202 having no inclined surface 26b is inserted into the concave portion 42, the vertical frame The component member 202 cannot be inserted to the bottom surface of the recess 42. Generally, the vertical frame constituting member 202 is provided with a screw hole 27a corresponding to the insertion hole 45a, and a screw 47 is inserted into the insertion hole 45a of the connector 40, and is screwed into the screw hole 27a to connect them. When the vertical frame constituent member 202 cannot be inserted to the bottom surface of the recess 42, the insertion hole 45a and the screw hole 27a are not aligned, and the operator cannot connect the two. Therefore, the operator can easily recognize erroneous insertion of the vertical frame component member 202 into the couplers 40 and 140.

  Further, by setting the distance set when the end surface of the vertical frame constituent member 202 is flat as the predetermined distance, the television receiver using the vertical frame constituent member 202 having the inclined surface 26b and the inclined surface 26b are provided. It is possible to prevent erroneous insertion of the vertical frame component 202 into the connectors 40 and 140 with a television receiver that does not use the vertical frame component 202.

The distance d1 between the center of the insertion hole 45a and the flat surface 26a is longer than the distance d2 between the center of the insertion hole 45a and the flat surface 26a in the television receiver on which the three-color display panel 10 is mounted. .

  The television receiver according to Embodiment 2 can be assembled simply by inserting the end of the vertical frame constituent member 202 into the recess 42 corresponding to the notch 26c, and a large space is required for the assembly of the front cabinet 20. It is not necessary, and thinning and narrowing of the frame can be maintained. Further, in one television receiver, a notch 26c is formed at the end of the vertical frame constituting member 202, and a recess 42 corresponding to the notch 26c is formed in the connector 40. In another television receiver, the notch 26c is formed. Incorrect insertion can be prevented by using the vertical frame constituent member 202 not having the frame and the connector 140 corresponding to the vertical frame constituent member 202.

  In addition, since the bottom surface of the concave portion 42 is disposed at a position separated by a predetermined distance or more from the insertion hole 45a through which the screw 47 is inserted, when the vertical frame constituent member 202 having no notch 26c is inserted into the concave portion 42, The frame constituent member 202 cannot be inserted up to the bottom surface of the recess 42. Generally, the vertical frame constituting member 202 is provided with a screw hole 27a corresponding to the insertion hole 45a, and a screw 47 is inserted into the insertion hole 45a of the connector 40, and is screwed into the screw hole 27a to connect them. When the vertical frame constituent member 202 cannot be inserted to the bottom surface of the recess 42, the insertion hole 45a and the screw hole 27a are not aligned, and the operator cannot connect the two. Therefore, the operator can easily recognize erroneous insertion of the vertical frame component member 202 into the couplers 40 and 140.

  Further, by setting the distance set when the end face of the vertical frame component member 202 is flat as the predetermined distance, the television receiver using the vertical frame component member 202 having the notch 26c and the vertical frame having the notch 26c. It is possible to prevent erroneous insertion of the vertical frame component 202 into the connectors 40 and 140 with a television receiver that does not use the component 202.
