Illuminating apparatus for liquid crystal display device

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;

FIG. 9 is an enlarged view of the portions 9 and 9 of FIG. 7 ; and,

FIG. 10 is an enlarged view of the portions 10 and 10 of FIG. 8.

The broken lines are shown in the views for illustrative purposes only and form no part of the claimed design.

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.
