Abstract: front page image
(EN) The objective of the present invention is to achieve reduction in contrast inconsistency on the emitting surface of a light guide plate. In a light source module according to the present invention, light path conversion sections (16) are arranged such that in the adjoining columns (16A and 16B), the distance (dx') in the X direction between the ends of the light path conversion sections (16) is smaller than the pitch (W) of a concavo-convex structure (T) and the distance (Px') in the X direction between the centers of the light path conversion sections (16) is larger than the pitch (W) of a concavo-convex structure (T).
(FR) La présente invention concerne la réduction d'incohérences de contraste sur la surface d'émission d'une plaque de guide lumineux. Dans un module de source lumineuse selon la présente invention, des sections (16) de conversion de trajet lumineux sont agencées de sorte que, dans les colonnes voisines (16A et 16B), la distance (dx') dans la direction X entre les extrémités des sections (16) de conversion de trajet lumineux soit inférieure au pas (W) d'une structure concavo-convexe (T) et la distance (Px') dans la direction X entre les centres des sections (16) de conversion de trajet lumineux est supérieure au pas (W) d'une structure concavo-convexe (T).
(JA) 導光板の出射面における輝度ムラの低減を実現する。 本発明の光源モジュールにおいて、光路変換部16は、隣接する列16A及び16Bにおいて、光路変換部16の端部間のX方向における距離dx'が凹凸形状体TのピッチWよりも小さく、かつ、光路変換部16の中心間のX方向における距離Px'が凹凸形状体TのピッチWよりも大きくなっている配置となっている。
