Description

  The present invention relates to a portable device and a manufacturing method thereof, and particularly to a portable device having a light emitting device such as liquid crystal or organic EL (Electro Luminescence) and a manufacturing method thereof.

  Various portable devices such as cellular phones, digital cameras, portable music players, and portable game machines are widely used. These mobile devices are required to have high functionality and multiple functions, as well as improvement in design and thinning of the housing. The increase in functionality and functionality of portable devices leads to an increase in the number of electronic components inside the housing, which contradicts the demand for thinner housings. For this reason, high-density mounting of boards and other components mounted inside the casing and efficiency inside the casing are required in order to realize thinning of the casing while increasing the functionality and functionality of portable devices. Various researches such as the arrangement of typical parts are underway.

  Further, the thinning of the housing has a great influence on the strength of the mobile device itself. The mobile devices such as the mobile phone and the digital camera described above have a display unit that displays images such as characters using liquid crystal, organic EL (Organic EL), and the like. Since only a thin glass plate with relatively low strength is placed on the surface of the display unit, the glass plate breaks due to impact or deformation from the outside of the housing and damages various members inside the display unit. For example, damage to the display unit is a major problem. In particular, there are many cracks from the edge of the glass. The cause is thought to be because microcracks or the like are likely to enter the glass edge in manufacturing.

FIG. 4 shows an example of related technology. The screen 14 made of glass or transparent resin and the outer frame 15 constitute a casing. The display unit 18 is housed in the frame 16 in the housing with the thin plate 20 interposed therebetween. A cushion 19 made of an elastic material such as rubber or sponge is sandwiched between the rib end portion 16a of the frame and the screen 14 so that an impact from the outside of the housing is not easily transmitted to the inside of the housing. The impact from the outside of the housing is propagated from the screen 14 or the outer frame 15 to the frame 16 via the cushion 19. Therefore, the impact from the outside of the housing does not propagate directly to the display unit, and the impact is absorbed by the cushion 19 so that the display unit 18 is not easily damaged (for example, Patent Document 1).
JP 11-122330 A

  In the method of Patent Document 1, the impact in the direction perpendicular to the screen 14 can be reduced by the cushion 19. However, the impact in the horizontal direction with respect to the screen 14 cannot be reduced.

  In addition, this method has an advantage that an impact can be absorbed because an elastic material such as rubber or sponge is used as the cushion 19. However, since the cushion 19 is made of an elastic material, the cushion 19 is easily deformed. FIG. 5 shows how the cushion 19 and the screen 14 are deformed when an impact is applied near the center of the screen 14. FIG. 5A shows a state before the force A is applied. FIG. 5B shows a state where a force A indicated by an arrow is applied from the state shown in FIG. In the state shown in FIG. 5B, the screen 14 is curved and comes into contact with the display unit 18. As shown in FIG. 5B, even if the cushion 19 is present, the cushion 19 is an elastic material, so that it is easily curved, and the display unit 18 cannot be protected from an impact near the center of the screen 16. In order to suppress the deformation of the cushion 19 and protect the display unit 18 from an impact near the center of the screen 16, if a highly rigid material is used as the cushion 19, the cushion 19 itself loses its elasticity and absorbs the impact. The cushion 19 cannot serve as a cushioning material.

  An object of the present invention is to provide a portable device that solves the above-described problem that the display unit incorporated in the casing of the portable device cannot be protected from an impact from the outside of the portable device.

  In the portable device having the display unit built in the housing of the present invention, the side surface and the end of the display unit are covered with a protective member. This display part is supported in the housing via a protective member. The protection member is composed of an elastic body and a reinforcing material included in the elastic body.

  According to the present invention, the side surface and the end of the display unit built in the housing of the portable device are covered with the protective member made of the elastic body and the reinforcing material included in the elastic body, and the display unit is protected. Since it supports in a housing | casing via a member, the impact from the exterior of a housing | casing becomes difficult to propagate to a display part, and a display part can be protected from the impact from the exterior of a housing | casing.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. In addition, the same number is attached | subjected to the structure which has the same function in an accompanying drawing, and the description may be abbreviate | omitted.

  FIG. 1 is a schematic configuration diagram of an embodiment of a portable device that protects a display unit according to the present invention.

  A casing is constituted by a screen 4 and an outer frame 5 made of glass or transparent resin. A display unit 8 using liquid crystal, organic EL, or the like is provided inside the housing, and the side surface and the end of the display unit 8 are covered with a recess of the protective member 3 having a U-shaped cross section. That is, the end portion of the display unit 8 is held by the protective member 3. The frame 6 inside the housing houses the display unit 8 and the protective member 3 that covers the side surface of the display unit 8. The protection member 8 is in contact with the screen 4 and the frame 6 and is positioned so as to be sandwiched. Therefore, the display unit 8 is fixed to the frame 6 via the protective member 3 and supported in the housing. The display unit 8 is located at a distance from the screen 4 by the protective member 3.

  A cross-sectional view of the protective member 3 used in the present embodiment is shown in FIG. The protective member 3 includes an elastic body 2 and a reinforcing material 1, and the elastic body 2 includes the reinforcing material 1. Therefore, the protection member 3 can maintain the same elasticity and higher rigidity than that of the elastic member 2 alone.

  When an impact from the vertical direction with respect to the display unit 8 is applied in the vicinity of the position of the screen 4 facing the end of the display unit 8, the display unit 8 is covered with the protection member 3 and the inside of the protection member 3. Since there is a reinforcing material 1, the impact is more difficult to propagate to the display unit 8 as compared with the protective member 3 constituted only by the elastic body 2.

  When an impact from a direction perpendicular to the display unit 8 is applied in the vicinity of a position facing the center of the display unit 8 of the screen 4, the cushion 19 is deformed in the related technology described above with reference to FIG. In some cases, the screen 14 is curved and the display unit 18 is damaged.

  On the other hand, FIG. 3 shows a state in which a force A indicated by an arrow is applied to a position facing the center of the display unit 8 of the screen 4 of the portable device of the present embodiment, as in FIG. Unlike the related art described above, the protection member 3 has high rigidity, and thus is difficult to be deformed. For this reason, the screen 4 is also difficult to bend, and the display unit 8 is hardly damaged.

  Even when an impact from the horizontal direction on the display unit 8 is applied to the screen 4 or the outer frame 5, the protective member 3 contains the reinforcing material 1, so that the impact is reduced by the elastic body 2, and the reinforcing material 1 However, since the propagation of the impact to the display unit 8 is blocked, the impact is less likely to propagate to the display unit 8 than the protective member 3 composed only of the elastic body 2.

  The elastic body 2 used for the protective member 3 is not particularly limited in material, but is preferably an anti-vibration rubber or silicon rubber. Furthermore, by making the elastic body 2 used for the protective member 3 the elastic body 2 having high thermal conductivity, heat generated from the inside of the display unit 8 and the like can be released from the display unit 8 to the outside, and the display unit by heat 8 failures can also be prevented.

  Moreover, although the material of the reinforcing material 1 is not limited, stainless steel such as SUS304 is preferable, and glass fiber, carbon fiber, or the like may be substituted.

  In the illustrated embodiment, the end portion is gripped by the protection member 3 over the entire circumference of the display unit 8, but only a part of the end portion of the display unit 8 is gripped by the protection member 3. You can also Also in that case, the display unit 8 is arranged at a distance from the screen 4 and the outer frame 5 by the protective member 3 so that the display unit 8 does not directly contact the screen 4.

  The present invention can be applied not only to a mobile phone, a digital camera, a portable music player, and a portable game machine, but also to a portable device having a large display unit such as a PDA or a notebook computer.

  According to the present invention, since the reinforcing material 1 blocks the impact from the horizontal and vertical directions on the screen 4, the display portion 8 is not easily damaged. Further, even when an impact is applied to the vicinity of the center of the screen 4, the protective member 3 has rigidity, so that the protective member 3 is hardly deformed, and damage to the display unit 8 due to deformation of the screen 4 can be suppressed. Further, since the reinforcing member 1 constituting the protective member 3 may be a thin plate, the protective member 3 does not hinder the thickness reduction of the portable device. The elastic body 2 and the reinforcing material 1 are not special materials, and the protective member 3 is also a composite material in which the reinforcing material 1 is included in the elastic body 2, which may cause a significant increase in manufacturing cost of the portable device.
