Abstract

A panel support structure for supporting a flat display panel capable of reducing the weight of the panel support structure while a sufficient structural strength is maintained and capable of preventing the display performance of the flat display panel from being lowered by a change in an ambient temperature. A flat display panel is fixedly supported by an X-character shaped supporting member via dampers fitted in the four corners of the flat display panel by the flat panel fixing parts of the supporting member. The supporting member is disposed along diagonal lines extending between the four corners of the flat display panel and has a rectangular cross section whose longer side is directed in the thickness direction of the flat display panel.

Claims

1. A panel apparatus comprising:

a panel for displaying an image and a panel support structure for supporting the panel, the support structure comprising;

a plurality of holding members, each of which is astride an edge of the panel, and

a supporting member having a metal rod-like structure, wherein one of said plurality of holding members is connected to each end of said rod-like structure.

2. A panel apparatus according to claim 1, wherein said holding members are provided with a damper at a position where the panel is adapted to come in contact with said holding members.

3. A panel apparatus according to claim 1, wherein said holding members are disposed generally along a surface of the panel.

4. A panel apparatus according to claim 1, wherein said supporting member includes a plate member.

5. A panel apparatus according to claim 1, wherein a length of said rod-like member along a longitudinal direction is greater than a length of a longer side of the panel.

6. A panel apparatus according to claim 1, wherein said panel is made of glass.

7. A panel apparatus according to claim 1, wherein said panel has a front glass substrate and a rear glass substrate which are adhered to one another.

8. A panel apparatus according to claim 1, wherein said supporting member comprises plural rod-like members crossing each other.

9. A panel apparatus according to claim 1, wherein a length of a cross section of said rod-like member along a thickness direction of the panel is greater than a length of the cross section along a direction parallel to a surface of the panel.

10. A panel apparatus according to claim 1, wherein a length of a cross section of said rod-like member along a thickness direction of the panel is at least 1/80 of a length of a diagonal line of the panel.

11. A panel apparatus according to claim 1, wherein said holding members alone, or said holding members and a part of said supporting member, contact with the panel.

12. A panel apparatus according to claim 1, wherein at least a portion of the panel support structure is electrically grounded.

13. A panel apparatus according to claim 1, wherein the panel support structure has a mount portion for mounting a cover which accommodates at least a portion of a panel display device that includes the panel and the panel support structure.

14. A panel apparatus according to claim 1, wherein the panel support structure has a mount portion for mounting a circuit board for controlling or driving the panel.
