Description

  The present invention relates to a display unit mounting structure, an electronic apparatus, and a shock absorbing method, and more particularly to a display unit mounting structure for a display unit such as a liquid crystal panel.

  In a cellular phone device or the like, a structure that prevents an impact on a housing from propagating to a display portion while being downsized and thinned is desirable in order to prevent damage to the display portion.

  FIGS. 11 to 13 show a structure for attaching a display unit to a housing in a mobile phone device or the like related to the present invention. 11 is a plan view of the display unit and the housing, FIG. 12 is a cross-sectional view taken along the line DD ′ of FIG. 11, and FIG. 13 is an enlarged view of a portion 130 of FIG. The housing 129 includes a display unit lower case 114 and a display unit upper case 113 fixed to the display unit lower case 114. A display unit 112 made of a liquid crystal panel or the like is attached to a display unit holder 115. A metal plate member 120 is embedded in the display unit holder 115 and the display unit upper housing 113, and the display unit holder 115 that holds the display unit 112 is supported by the housing 129 via the plate member 120. ing. A display unit holder fitting portion 116 is formed on the display unit holder 115, and a display unit upper case fitting unit 117 is formed on the display unit upper case 113. The display unit 112 is positioned with respect to the housing 129 by the claw fitting between the display unit holder fitting unit 116 and the display unit upper housing fitting unit 117.

  Patent Document 1 discloses a display holding component for holding a display having a holding wall, a frame portion, and a tongue portion. The holding wall is formed with an opening that covers the periphery of the display to be held and exposes the display surface. The frame portion has a claw receiving portion for locking with the fixed portion. The tongue portion is formed in a part of the frame portion and extends to a position facing the opening so as to form a gap for holding the indicator between one surface side of the holding wall. The frame part and the tongue part are formed of an elastic member.

  Patent Document 2 discloses a fitting claw that is formed by bending a sheet metal at approximately 90 degrees, and the bent tip is disposed so as to face a direction substantially perpendicular to the plane direction of the liquid crystal panel. When a liquid crystal holder to which the liquid crystal panel is fixed is mounted on the housing, the tip bent at approximately 90 degrees is fitted into the fitting recess of the liquid crystal holder, and a large impact is applied due to, for example, dropping. Even in this case, the liquid crystal panel can be reliably held by the casing which is a sheet metal part without being displaced in a direction substantially perpendicular to the plane direction.

  Patent Document 3 discloses a display device in which a panel module including a display panel and a drive circuit for driving the display panel is sandwiched between a front casing and a rear casing. Here, the front housing is located on the display surface side of the display panel, and the rear housing is located on the back side of the display panel. A cushioning member is arranged on the back surface near the side edge of the panel module, and the end of the cushioning member on the center side of the display panel covers the periphery of the display area of the display panel. It is located further on the display panel center side. A predetermined space is formed between the center side of the display panel and the back surface of the panel module.
