Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a structure for holding an LCD display panel of a portable device (particularly, a portable telephone).
[0002]
[Prior art]
The structure of a conventional LCD display mounting structure is such that a substrate is provided in a main body case having an opening, and an LCD display is disposed between the substrate and the opening. A cushion is interposed between the display and the LCD and the substrate, and the LCD is interposed between the main body case and the substrate.
In the LCD display mounting structure configured as described above, when an impact force or a pressing force is applied to the upper surface of the main body case, the cushions sandwiching the LCD display up and down cooperate to absorb the impact, and the LCD display is mounted. The external force acting on the surface is reduced (for example, see Patent Document 1).

[Problems to be solved by the invention]
However, in recent years, due to market demands for lighter and thinner mobile phones, the thickness of the outer casing and the thickness of the LCD display panel have been reduced, resulting in insufficient strength performance of the phone body and damage to the LCD display panel. It has increased.
In addition, as the use of multimedia terminals as multimedia terminals has expanded due to digitization, the size of the LCD display panel has been urgently required to display a large amount of information. In addition, the impact resistance is reduced, and the damage of the LCD display panel is increased.
[0005]
The present invention has been made in order to solve the above-described problems, and has a high strength performance against an impact applied to an exterior housing and the like, and an LCD display panel holding structure capable of positioning an LCD display panel. The purpose is to provide.
[0006]
[Means for Solving the Problems]
An LCD display panel holding structure according to the present invention includes an exterior housing, an LCD holder provided in the exterior housing, and holding the LCD display panel, and an impact applied to the exterior housing, which is provided in the LCD holder. And an elastic portion for relaxing so as not to be transmitted to the panel.

BEST MODE FOR CARRYING OUT THE INVENTION
Embodiment 1 FIG.
Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.
1 to 5 show the first embodiment, FIG. 1 is an external perspective view of a mobile phone, FIG. 2 is an exploded perspective view of an LCD display of the mobile phone, and FIG. 3 is a cross-sectional view of the LCD display of the mobile phone. FIG. 4 is an enlarged view of a portion A in FIG. 3, and FIG. 5 is an explanatory view of how an impact is transmitted.
[0008]
As shown in FIG. 1, the mobile phone includes an LCD display unit 1 and a button operation unit 2.
[0009]
As shown in FIGS. 2 and 3, the LCD display panel 3 is held by an LCD holder 4, and the LCD holder 4 is disposed between a portion for housing and holding the LCD display panel 3 and a holding portion for the exterior housing 5. In addition, a U-shaped elastic portion 7 is provided. The LCD holder 4 is made of a sheet metal or a resin member. For example, a sheet metal is aluminum, stainless steel, or the like, and a resin is polycarbonate, ABS, or the like. The LCD holder 4 provided with the elastic part 7 is assembled together with the screw part of the outer casing 5 using the screw 6.
[0010]
The operation of the thus configured LCD display panel holding structure will be described with reference to FIGS. When an impact is applied to the outer casing 5 from the outside of the mobile phone due to, for example, dropping, the outer casing 5 is deformed. In accordance with this amount of deformation, an impact is transmitted to the LCD holder 4 via the contact surface 8 of the exterior housing 5, and the elastic portion 7 of the LCD holder 4 is deformed as shown in FIG. When the elastic portion 7 is deformed, the rest of the absorbed shock is transmitted through the inside of the LCD holder 4 and transmitted to the LCD display panel 3 via the contact surface 9 of the LCD holder 4. In this manner, the elastic portion 7 of the LCD holder 4 absorbs the shock applied from outside the mobile phone.
[0011]
According to this LCD display panel holding structure, the shock applied to the LCD display panel 3 from the outside of the mobile phone can be sufficiently absorbed by the elastic portion 7 of the LCD holder 4, and the LCD display panel 3 can be prevented from being damaged. .
[0012]
According to this LCD display panel holding structure, the LCD holder 4 is formed of a sheet metal or a resin member instead of absorbing the impact with the cushion, and the elastic portion 7 of the LCD holder 4 absorbs the impact. The LCD display panel 3 can be positioned at an appropriate position by applying the LCD display panel 3 to the exterior housing 5 at a position outside the elastic portion 7 of the LCD holder 4 in a state where no shock is applied. The shock can be absorbed without generating a shift. In addition, since the impact is absorbed by the LCD holder 4 instead of the cushion, the object can be achieved without adding components.
[0013]
Also, when an impact is applied, the elastic portion 7 of the LCD holder 4 is not plastically deformed, and when the impact is released, the LCD display panel 3 returns to an appropriate position, and no displacement occurs. .
[0014]
In addition, as the LCD display panel 3, a thin glass panel having a thickness of 0.4 mm or less can be employed corresponding to the increase in impact resistance, and the thickness of the mobile phone can be reduced.
[0015]
Although the shape of the elastic portion 7 of the LCD holder 4 is shown as a U-shape, the shape is not limited to this shape and may be another shape. For example, it may be U-shaped or bellows-shaped.
[0016]
According to the above-described embodiment, the shock applied to the LCD display panel 3 from the outside of the mobile phone can be sufficiently absorbed by the elastic portion 7 of the LCD holder 4, and the damage of the LCD display panel 3 can be prevented.
[0017]
Further, the LCD display panel 3 can be positioned at an appropriate position by contacting the LCD display panel 3 with the exterior housing 5 at a position outside the elastic portion 7 of the LCD holder 4 in a state where no normal impact is applied. The impact can be absorbed without causing the positional deviation of the third position.
[0018]
In addition, the LCD display panel 3 can reduce the thickness of the mobile phone corresponding to the increased shock resistance.
[0019]
In addition, since the impact is absorbed by the LCD holder 4 instead of the cushion, the object can be achieved without adding components.
[0020]
【The invention's effect】
An LCD display panel holding structure according to the present invention includes an exterior housing, an LCD holder provided in the exterior housing, and holding the LCD display panel, and an impact applied to the exterior housing, which is provided in the LCD holder. With the provision of the elastic portion that relaxes so as not to be transmitted to the panel, the shock applied to the LCD display panel from the outside can be absorbed by the elastic portion of the LCD holder, and the damage of the LCD display panel can be suppressed. .
