Edge-type backlight module

An edge-type backlight module comprising:

• a light guide plate having at least one light-incident sidewall;
• at least one linear light source arranged substantially parallel to the at least one light-incident sidewall and comprising:
• a carrier equally divided into a first, a second, a third, a fourth, and a fifth device mounting regions sequentially arranged along an extending direction of the carrier;
• and
• a plurality of solid-state light-emitting devices mounted on the first, the second, the third, the fourth, and the fifth device mounting regions of the carrier and electrically connected to the carrier, wherein normal forward voltage bins of the solid-state light-emitting devices on the fourth device mounting region are lower than normal forward voltage bins of the solid-state light-emitting devices on the first, the second, the third, and the fifth device mounting regions.
