Description
The article according to the design is incorporated in a portable
telephone, a portable terminal for information device, etc. so as
to illuminate a liquid crystal display from the front side.
Light emitted from the light source, traveling through a light
conductive member and a light diffusing plate and introduced into a
light conductive plate uniformly illuminates the whole surface of
the liquid crystal display thanks to micro-prisms formed on the
surface of the light conductive plate.
A transparent cover is provided over the exposed surface of the
article incorporated in the portable telephone, etc. so as to
protect the micro-prisms from dust, dirt, scratches, etc.
FIG. 1 is a front view of an illuminating apparatus for liquid
crystal display device showing our new design;
FIG. 2 is a top plan view thereof;
FIG. 3 is a bottom view thereof;
FIG. 4 is a left side view thereof;
FIG. 5 is a right side view thereof;
FIG. 6 is a rear thereof;
FIG. 7 is a cross-sectional view taken along the line 7--7 of FIG.
1;
FIG. 8 is a cross-sectional view taken along the line 8--8 of FIG.
1; and,
FIG. 9 is an enlarged view of the portions 9 and 9 of FIG. 7.
A light source (i.e., light emitting diode) for illumination is
disposed inside a housing frame which is shown at the lower side of
FIG. 1.
Two flexible printed circuit boards extending downwardly in FIG. 1
are connected to a power source.
