Abstract

A display means for an apparatus comprising a printed circuit board having an integrated circuit etc. for controlling display information; a backlighting plate being fixed on the printed circuit board; a glass-electrode liquid crystal display device which is disposed on the backlighting plate and is electrically connected with the printed circuit board through a flexible printed circuit plate and fixed thereon; a decorative panel being located above the glass-electrode liquid crystal display device; and an elastic packing which is disposed between the glass-electrode liquid crystal display device and the decorative panel and is fixed on this side of the printed circuit board to hold the glass-electrode liquid crystal display device.

Claims

1. A display means for an apparatus, comprising:

a printed circuit board having an integrated circuit for controlling display information;

a backlighting plate fixed on the printed circuit board;

an L.C.D, panel Which is disposed on the backlighting plate, and is electrically connected With said printed circuit board through a flexible circuit board;

a transparent panel for covering the L.C.D. panel, located above said L.C.D. panel; and

an elastic packing which is formed integrally between said L.C.D. panel and said transparent panel to protect said L.C.D. panel from shock and to prevent dust from entering between said L.C.D. panel and said transparent panel, and is fixed to said backlighting plate to hold the L.C.D. panel to the backlighting plate,

wherein a plurality of continuous ridges are formed on a first surface of said elastic packing which contacts said L.C.D. panel so as to enclose an opening formed in said elastic packing, and a continuous ridge is formed on a second surface of said elastic packing which contacts said transparent panel so as to enclose said opening, the ridges being positioned zigzag with respect to one another on said first and second surfaces of said elastic packing wherein said ridge on said second surface is located between two of said ridges on said first surface.
