Description

  The present invention relates to a frame device combined with an outer peripheral edge portion such as a casing of various electronic devices, and a flat display device such as a liquid crystal display device including the frame device.

  For example, flat display devices such as a liquid crystal display device and a plasma display device are positioned as the most important fixtures among indoor fixtures with the increase in size, and each is provided with a unique housing design. In Patent Document 1, a housing that accommodates a display panel is formed by extending both side portions, and this extended portion constitutes a superposed portion of the front glass plate and constitutes an attachment portion of the speaker unit. There is disclosed a flat display device in which an overlapping portion with a front glass plate is hidden by a speaker unit. Further, Patent Document 2 discloses a flat display device in which a front glass plate superimposed on an upper edge portion and a lower edge portion of a bracket for attaching a display panel is sandwiched and held by a holding member.

  On the other hand, in the case of a flat panel display or various electronic equipment casings, etc., the outer peripheral part and the internal structure are mechanically protected against external loads, and the purpose is to conceal the binding part and improve the original design. As described above, it is preferable that the outer peripheral edge of the housing is covered over the entire area with a frame member. In a flat display device or the like, a frame structure is generally configured by combining a frame device made of a frame member made of an aluminum material or the like with an outer peripheral edge portion of a housing.

  In a conventional flat display device or the like, a frame member that is integrally formed by aluminum die casting or the like that can form a seamless and highly accurate corner portion is generally used as a frame member that constitutes a frame device. It is done. In such a frame device, as the flat panel display device is increased in size, the frame member that becomes large is likely to be twisted or distorted as a whole, and the case is made of a synthetic resin casing that has a greatly different coefficient of thermal expansion. At the time of attachment, there has been a problem that the positional deviation of the attachment portion becomes large, making the adjustment troublesome and creating a gap. Also, in such a frame device, an expensive die-cast mold is used to form a large frame member, and a heavy load frame member is handled, which increases the burden on the assembly process and the conveyance process. There was also a problem that efficiency was lowered and cost was increased.

  In a flat display device or the like, for example, a frame member is divided into a simple-shaped horizontal frame member and a vertical frame member, and the horizontal frame member and the vertical frame member are assembled to a mounting panel member as a countermeasure for an increase in size. It is also considered to reduce costs and improve productivity. However, in such a flat display device or the like, even if the horizontal frame member and the vertical frame member can be formed with high accuracy in units of parts, due to assembly accuracy with respect to the mounting frame member, dimensional error due to temperature change, etc. In particular, there is a problem that occurs when the accuracy of the corner portion configured by abutting each tip portion in an orthogonal state decreases.

  On the other hand, in flat display devices and the like, aluminum horizontal frame members and vertical frame members are relatively lightweight, so the fixed part is not exposed to the outside and is attached using an adhesive as a simple method. A structure that is joined to the outer peripheral edge of the panel member is employed. However, in such a flat display device or the like, it is difficult to stably join the horizontal frame member and the vertical frame member to the mounting panel member over the entire area.

  In a flat display device or the like, static electricity is easily charged to a human body in a dry room in winter or the like, and when an aluminum frame member is used, a discharge phenomenon may occur when touched. Therefore, in a flat display device or the like, a structure for grounding the frame member is required, but there is also a problem that it is difficult to cope with it when an adhesive structure is used.
