Abstract:
1. A front light module, comprising: a light source, being capable of emitting an incident light; a light guide plate, having a side face and a bottom surface connected to said side face, wherein said light guide plate has a first refractive index and said side face neighbors said light source and is capable of receiving said incident light; and a plurality of pillar structures, being placed under said bottom surface of said light guide plate, wherein said pillar structures have a second refractive index and said second refractive index of said plurality of pillar structures is larger than said first refractive index of said light guide plate; wherein a light traveling in said light guide plate is diverted downwardly toward a display device when incident on said pillar structures; wherein a fixing frame is used with a reflective cover to bond said light guide plate, said pillar structures, and said display device together, both a first width of a first opening of said reflective cover and a second width of a second opening of said fixing frame are smaller than a total thickness of said light guide plate, said pillar structures, and said display device, and opposing side faces of said light guide plate, said pillar structures, and said display device are secured in said first opening of said reflective cover and said second opening of said fixing frame respectively.
