附图说明
通过结合附图进行的以下描述，本发明的实施例的上述和其它方面、特点和优点将变得更加清楚，附图中：
图1是根据本发明的实施例的液晶显示装置的结构示意图；
图2是根据本发明的实施例的背光模块的侧视示意图。
具体实施方式
以下，将参照附图来详细描述本发明的实施例。然而，可以以许多不同的形式来实施本发明，并且本发明不应该被解释为限制于这里阐述的具体实施 例。相反，提供这些实施例是为了解释本发明的原理及其实际应用，从而使本领域的其他技术人员能够理解本发明的各种实施例和适合于特定预期应用的各种修改。
图1是根据本发明的实施例的液晶显示装置的结构示意图。
参照图1，根据本发明的实施例的液晶显示装置包括液晶显示面板200及与液晶显示面板200相对设置的背光模块100，其中，背光模块100提供显示光源给液晶显示面板200，以使液晶显示面板200显示影像。
液晶显示面板200通常包括薄膜晶体管(Thin Film Transistor，简称TFT)阵列基板210、与TFT阵列基板相对设置的彩色滤光片(Color Filter，简称CF)基板220以及夹设于TFT阵列基板210与CF基板220之间的液晶层230，其中，液晶层230中包括若干液晶分子。由于本实施例的液晶显示面板200的具体结构与现有技术的液晶显示面板的结构基本一致，所以在此不再详细描述。
以下将对根据本发明的实施例的背光模块100的具体结构进行详细的描述。
图2是根据本发明的实施例的背光模块的侧视示意图。
参照图2，根据本发明的实施例的背光模块100包括：导光板110、光源组件120、V形沟槽130、第一增亮膜片141和第二增亮膜片142、扩散膜片150、反射片160。应当理解的是，根据本发明的实施例的背光模块100还包括其他必要的光学部件。
具体而言，导光板110包括入光端部110a，其中，该入光端部110a包括倾斜侧面111、垂直侧面112、底面113及顶面114。这里，底面113即为导光板110的底面，顶面114即为导光板110的顶面。顶面114与底面113相对平行设置，顶面114与倾斜侧面111的一端连接，倾斜侧面111的另一端与垂直侧面112的一端连接，底面113与垂直侧面112的另一端连接，多个沿预定方向延伸的V形沟槽130设置在倾斜侧面111上。
光源组件120邻近于入光端部110a设置，并与入光端部110a相对设置。具体为，光源组件120包括支撑架121及光源122，其中，支撑架121包括倾 斜面1211，该倾斜面1211与入光端部110a的倾斜侧面111相对平行设置，光源122固定设置在倾斜面1211上。在本实施例中，优选的，光源122为发光二极管(LED)。
这样，光源122发出的光照射到倾斜侧面111上，倾斜侧面111上设置的V形沟槽130会对照射到其上的光进行扩散，经扩散后的光在入光端部110a均匀一致，不会在入光端部110a形成亮暗不均(Hot Spot)现象。
第一增亮膜片141、第二增亮膜片142、扩散膜片150依序设置在导光板110的顶面114之上，其中，第一增亮膜片141和第二增亮膜片142用于汇聚由顶面114出射的光，以提高由顶面114出射的光的亮度；扩散膜片150用于提升经第一增亮膜片141和第二增亮膜片142后的光的向上亮度，并将经第一增亮膜片141和第二增亮膜片142后的光柔散化，从而向液晶显示面板200提供均匀的面光源。反射片160设置在导光板110的底面113之下，用于将由导光板110的底面113出射的光反射回导光板110中，以提供导光板110中光的利用率。
在本实施例中，优选的，V形沟槽130延伸的预定方向与导光板110的宽度方向平行。此外，根据制作需求，可将倾斜侧面111与底面113的夹角范围设定为10°～80°。
另外，V形沟槽130包括以预定夹角相连的第一槽面131和第二槽面132。优选的，该预定夹角为90°。在本实施例中，第二槽面132的宽度方向与导光板110的宽度方向平行，即第一槽面131与底面113或顶面114垂直。
由于入光端部110a的底面113与倾斜侧面111相对，光源122发出的光通过倾斜侧面111直接照射到入光端部110a的底面113上，会使入光端部110a的底面113亮度过大，所以在入光端部110a的底面113上设置若干网点1131。在本实施例中，优选的，该网点1131为内凹的圆槽。
此外，支撑架121还包括顶表面1212和垂直面1213，其中，顶表面1212与顶面114平齐，顶表面1212与倾斜面1211的一端连接，垂直面1213与垂直侧面112相对平行设置，垂直面1213与倾斜面1211的另一端连接。
为了将由垂直侧面112出射的光反射回导光板110中，以提高光的利用率，光源组件120还包括反射元件123，其中，反射元件123设置在垂直面1213上，以与垂直侧面112相对。在本实施例中，反射元件123可例如为金属铝反射膜或者其他合适类型的反射元件。
为了避免光源122发出的光向上侧漏，光源组件120还包括遮光元件124，其中，该遮光元件124设置在顶表面1212与倾斜面1211的连接处，该遮光元件124的顶面与顶表面1212平齐。在本实施例中，遮光元件124可例如为截面呈三角形状的黑色遮光带，但本发明并不限制于此。
虽然已经参照特定实施例示出并描述了本发明，但是本领域的技术人员将理解：在不脱离由权利要求及其等同物限定的本发明的精神和范围的情况下，可在此进行形式和细节上的各种变化。
