Description

背光模块及显示装置 技术领域
本发明涉及一种背光模块及显示装置，特别是涉及一种直下式入光背光模块及其应用的显示装置。
 背景技术
液晶显示器(Liquid Crystal Display，LCD)已被广泛应用于各种电子产品中，液晶显示器大部分为背光型液晶显示器，其是由液晶显示面板及背光模块(backlight module)所组成。背光模块可依照光源入射位置的不同分成侧向式入光(Side-light type)与直下式入光(Direct-light type)两种，以便提供背光源至液晶显示面板。以直下式的背光模块为例，其可使用多个灯管或灯条(light bars)来作为光源，以提供一背光给液晶显示面板。
然而，侧向式入光或直下式入光背光模块的光源的光线需通过导光板或扩散板来形成一面光源，因而增加背光模块的重量及组装步骤。
故，有必要提供一种背光模块及显示装置，以解决现有技术所存在的问题。

 有益效果
本发明的背光模块及显示装置可通过透镜片来均匀光源的光线，以形成一均匀的平面光源，因而可省略现有导光板或光学膜片的设置。因此，本发明的背光模块及显示装置可减少其整体重量，并简化组装步骤。
附图说明
图1显示本发明的第一实施例的背光模块与显示面板的部分剖面示意图；
图2显示依照本发明的第一实施例的透镜片的下视图；以及
图3显示依照本发明的第二实施例的透镜片的部分剖面示意图。
 本发明的最佳实施方式
以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。
在图中，结构相似的单元是以相同标号表示。
请参照图1，其显示依照本发明的第一实施例的背光模块与显示面板的剖面示意图。本实施例的背光模块100可为直下式背光模块，其相对于一显示面板101来设置，所述显示面板101可为液晶显示面板，而形成一显示装置，如液晶显示装置等。背光模块100可包括背板110、多个光源120、电路板130、反射层140及透镜片150。
如图1所示，本实施例的背板110是由不透光材质所制成，例如：塑化材料、金属材料或上述材料的组合，用以承载光源120、电路板130及透镜片150。光源120是设置在电路板130上，并电性连接于电路板130，用来为显示面板101提供光线。光源120优选为点光源(point light source)，例如发光二极管(Light-Emitting Diode，LED)、有机发光二极管(Organic Light Emitting Diode，OLED)或电激发光(Electro-Luminescence，EL)组件。在本实施例中，光源120可为多个发光二极管芯片，其排列于电路板130，且每二相邻光源120之间具有一预设间隔。
如图1所示，本实施例的电路板130设置在背板110上，并电性连接于光源120，用于控制光源120的发光。电路板130可为印刷电路板(Printed circuit board，PCB)或柔性印刷电路板(Flexible Printed Circuits，FPC)。
如图1所示，本实施例的反射层140可设置于电路板130上，并形成于这些光源120之间。反射层140可为反射板或反射片，用来反射光源120的光线。此反射层140是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、其上述任意组合的合金或耐黄化且耐热的白色反射漆料等。
请参照图1和图2，图2显示依照本发明的第一实施例的透镜片的下视图。本实施例的透镜片150可利用射出成型(Injection Molding)、冲压、裁切、精密铸造、铸造、机械加工、压铸或锻造方式来一体成型。透镜片150的材料例如为光硬化型树脂、聚甲基丙烯酸甲酯(PMMA)或聚碳酸酯(PC)。透镜片150包括出光面151、底面152、多个凹部153及荧光层154。出光面151是形成于透镜片150的一侧，并面对液晶显示面板101，用以允许光源120的光线被发出至液晶显示面板101。底面152是形成于透镜片150的另一侧，并面对于电路板130。透镜片150的凹部153是形成于底面152上，用以容置及封装光源120，且每一凹部153可作为凹透镜(concave lens)，用以扩散光源120的光线。因此，通过透镜片150的凹部153，光源120的光线可被扩散且均匀化，而达到混光的效果，以提供一均匀的面光源至液晶显示面板101。荧光层154是形成于每一凹部153的内表面，并可被光源120的光线所激发，而发出可见光。因此，通过荧光层154，可改善光源120的发光效率或改变光源120的光色。
在本实施例中，每一凹部153的开口面积是至少大于每一光源120的宽度，以使光源120容置于透镜片150的凹部153内。依据透镜片150的光学设计，凹部153的剖面形状可呈梯形、半圆或其它任意形状。再者，依据使用者的实际需求，凹部153的凹透镜形状或尺寸亦可被调整，以形成最佳的且均匀的面光源。
当组装本实施例的显示装置时，排列有光源120的电路板130可先设置于背板110上，接着，可设置透镜片150于电路板130上。此时，光源120是对应地容设及封装于透镜片150的凹部153内。接着，设置显示面板101于透镜片150上，以完成显示装置。
因此，通过本实施例的透镜片150，可均匀化背光模块100的光源120的光线，以形成一均匀的平面光源，因而可省略现有导光板或光学膜片的设置。由于本实施例的背光模块100可省略导光板或光学膜片，因而减少其整体重量，并简化背光模块100的组装步骤。再者，由于光源120的光线是预先利用透镜片150的凹透镜来进行混光，因而可缩短光线所需的混光空间，而可减少背光模块100的厚度。
请参照图3，其显示依照本发明的第二实施例的透镜片的部分剖面示意图。以下仅就本实施例与第一实施例间的相异处进行说明，而其相似处则在此不再赘述。相较于第一实施例，第二实施例的背光模块的透镜片250包括出光面251、底面252、多个凹部253及荧光层254。出光面251和底面252是位于透镜片250的相对两侧，凹部253是形成于底面252上，用以容置及封装光源120，荧光层254是形成于每一凹部253的内表面，并可被光源120的光线所激发，而发出可见光。第二实施例的透镜片250的出光面251可设有多个突出结构255，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255可例如为：棱形或半圆形的凸起或凹陷结构等。再者，出光面251更可具有雾面处理或散射点设计，以便均匀化光源120的光线，减少出光不均(Mura)的现象。
由上述可知，本发明的背光模块及显示装置可通过透镜片来均匀化光源的光线，以形成一均匀的平面光源。因此，本发明的背光模块可省略现有导光板或光学膜片的设置，以减少整体重量，并简化背光模块的组装步骤。
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。
