摘要:
A side-light type backlight includes a light source having a plurality of LEDs and a light guide plate, where opposing end surfaces of the light guide plate define light incidence surfaces, with the plurality of LEDs being arranged at one of the light incidence surfaces. A number, M, of the LEDs are arranged in a longitudinal direction of the light incidence surface of the light guide plate, and are electrically connected such that there are a plurality of groups of the LEDs with each group having N LEDs mutually adjacently arranged in series. The groups are adjacently arranged in a longitudinal line, and at least one of the groups of LEDs is a separate parallel connection from an adjacent group of LEDs. The plurality of LEDs includes LEDs having a plurality of colors, and the LEDs arranged in series include LEDs having different colors.

A side light type backlight includes a light source including a plurality of LEDs, and a light guide plate. One of the end surfaces of the light guide plate is a light incidence surface at which a plurality of R-LEDs, a plurality of G-LEDs and a plurality of B-LEDs are arranged. LEDs satisfy the relationship of: a distribution range of light emitted from G-LEDs
摘要:
A backlight unit has a light source, a reflection sheet, a light guide plate, an air space, and a diffuser, wherein the reflection sheet, the light guide plate, the air space, and the diffuser are overlaid in this order. The light source is configured to arrange individual light sources having different spectra or different light emission quantities near an incident plane of the light guide plate, and on a plane facing the reflection sheet of the light guide plate, scatter dots are disposed which take light propagating through the light guide plate out of the reflection sheet side. The backlight unit and a liquid crystal display device including the same have excellent display quality.
