如图1所示，本实施例的导光板130是设置于光纤固定基板120的一侧。导光板130可利用射出成型(Injection Molding)的方式来制成，其材料为光硬化型树脂、聚甲基丙烯酸甲酯(PMMA)或聚碳酸酯(PC)，用以导引光纤110所传送的光线至液晶显示面板101。导光板130具有出光面131、光反射面132及侧入光面133。出光面131形成于导光板130的一侧，并面对液晶显示面板101，出光面131可具有雾面处理或散射点设计，以便均匀化导光板130的出光，减少出光不均(Mura)的现象。在另一实施例中，出光面131更可设有若干个突出结构(未绘示)，以便进一步修正光线的方向，来增加聚光效果，并提高正面辉度。其中此些突出结构可例如为：棱形或半圆形的凸起或凹陷结构等。光反射面132是形成导光板130相对出光面131的另一侧，用以反射光线至出光面131。在本实施例中，导光板130的光反射面132平行于出光面131。光反射面132可设有导光结构(未绘示)，以反射导引光线由出光面131射出。光反射面132的导光结构例如是呈连续性的V形结构，亦即V-Cut结构、雾面结构、散射点结构，以便导引光纤110所传送的光线充分的由出光面131射出。侧入光面133形成于导光板130的一侧或相对两侧，其面对于光纤固定基板120的出光口121，用以允许光纤110所传送的光线可进入导光板130内。且此侧入光面133可具有例如V形结构(V-Cut)、S形波浪结构或表面粗糙化处理(未绘示)，以此提升光线的入射效率和光耦合效率。
如图2所示，本实施例的集光器140是连接于光纤110的一端，用于收集外界光线，例如太阳光。集光器140可包括基座141、光学透镜142、光传感器143及外罩144。光学透镜142及光传感器143可设置于基座141上，光学透镜142用于收集外界光线，并提供所收集的光线于光纤110的入光端116。光传感器143可用于感测外界光线，以控制基座141对应于外界光源(如太阳)来转动，而提高光收集效率。外罩144是用于包覆光学透镜142及光传感器143，且外罩144可具有紫外线过滤层(未显示)，以过滤外界光线中的紫外线。
如图1所示，在本实施例中，背板150是由不透光材质所制成，例如：塑胶材料、金属材料或上述材料的组合，用于承载光纤固定基板120及导光板130，其中背板150可具有对应通孔(未显示)，以允许光纤110穿过。反射层160(或反射片)优选可形成导光板130的光反射面132的表面，而仅暴露出用以允许光线进入的侧入光面133以及用以发出光线的出光面131。反射层160可由高反射率材料所制成，例如银、铝、金、铬、铜、铟、铱、镍、铂、铼、铑、锡、钽、钨、锰、上述任意组合的合金、耐黄化且耐热的白色反射漆料或上述材料的任意组合，以反射光线。光学膜片170例如为：扩散片、棱镜片、逆棱镜片(Turning Prism Sheet)、增亮膜(Brightness Enhancement Film，BEF)、反射式增亮膜(Dual Brightness Enhancement Film，DBEF)、非多层膜式反射偏光片(Diffused Reflective Polarizer Film，DRPF)或上述的任意组合，其设置于导光板130上，用以改善由导光板130出光的光学效果。
当使用本实施例的背光模块来提供背光源时，光纤110可将集光器140所收集的外界光线(如太阳光)传送至导光板130。更具体地，集光器140所收集的光线可经由光纤110来进行传送，并通过光纤固定基板120的出光口121来发出至导光板130。由于背光模块100是使用外部的光线来提供背光源，因而可大幅地减少光源的电力耗费。且外界的光线(如太阳光)一般可具有较宽的色域，故使用背光模块100的显示装置可提供具有真实色彩的影像，大幅地改善显示装置的影像显示质量。
请参照图4，其为本发明背光模块的另一实施例的示意图。在另一实施例中，光纤固定基板120更可包括多个光源122，例如为发光二极管(LED)或有机发光二极管(Organic Light Emitting Diode，OLED)。光源122可排列于出光口121之间，并面对于导光板130的侧入光面133。当集光器140所收集的光线不足以提供来形成面光源时，光源122可提供额外的光线于导光板130，以确保背光模块100所形成的背光源具有足够的亮度。
由上述可知，本发明的背光模块和显示装置可收集外界光线来形成背光源，因而可大幅地减少光源的电力耗费，且可改善显示装置的影像色彩表现，以改善显示装置的影像显示质量。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
