LIGHT SOURCE MODULE AND ELECTRONIC DEVICE INCLUDING SAME
First Claim
1. A light source module comprising:
- a plurality of light guide bodies provided in parallel to one another with respect to a longitudinal direction;
light sources each causing light to enter each of the plurality of light guide bodies from at least one end surface in a longitudinal direction of the each of the light guide bodies;
a light source wiring board having the light sources and lines provided thereon, the lines being for electrically connecting the light sources and including positive potential lines and negative potential lines; and
a light source drive circuit for performing a drive for turning on the light sources,the light sources provided for the plurality of light guide bodies being independently driven by the light source drive circuit so that each of the light sources is independently turned on,the lines being arranged so that at least two high potential lines are arranged to be a common line, the lines being provided on the light source wiring board connected to the light sources.

Abstract
A light source module of the present invention includes: a plurality of light guide bodies (21) provided in parallel to one another with respect to a longitudinal direction; light sources (30) each causing light to enter each of the plurality of light guide bodies from at least one end surface in a longitudinal direction of the each of the light guide bodies (21); a light source wiring boards (32) having the light sources (30) and lines provided thereon, the lines being for electrically connecting the light sources (30) and including positive potential lines and negative potential lines; and an LED driver circuit (40) for performing a drive for turning on the light sources (30). Each of the light sources (30) provided to the light guide bodies (21) are independently driven by the LED driver circuit (40) so that each of the light sources (30) is independently turned on. Among lines provided on the light source wiring board (32) connected to the light sources 30, at least two high potential anode lines (30a) is arranged to be a common line. This makes it possible to provide a light source module whose thickness can be reduced by reduction of a wiring area, and an electronic device including the light source module, in a case where a side edge light guide plate is divided into a plurality of blocks.
