Description

背光模块及具有该背光模块的液晶显示器 技术领域
本发明属于液晶显示技术领域，具体地讲，涉及一种实现窄边框化的同时加强反射片牢固度的背光模块及具有该背光模块的液晶显示器。
背景技术
随着信息社会的发展，人们对平板显示器的需求得到了快速的增长。液晶显示器(Liquid Crystal Display，简称LCD)具有体积小、功耗低、无辐射等特点，在当前的平板显示器市场占据了主导地位。
近年来随着人们对视觉享受的不断提高，窄边框化成为液晶显示器的主流发展方向。为做到实现液晶显示器的窄边框化，导光板与光学膜片的侧壁与液晶显示器的可视区边界的距离将大幅减小，胶框侧壁的宽度也被大幅减小。然而，由于胶框、双面胶以及反射片自身的尺寸在加工时会有误差，在这种情况下，胶框侧壁的宽度被大幅减小后，反射片的粘合面积得不到保障，其粘合的牢固程度也大大地降低，加大了液晶显示器的装配难度，并且不利于提高制程的良率。
发明内容
为了解决上述现有技术存在的问题，本发明的目的在于提供一种背光模块，包括：导光板、胶框及反射片，所述导光板包括侧面及底面，所述胶框的底部朝向所述侧面沿伸以配合于所述侧面与所述底面之间，所述反射片设置于所述导光板与所述胶框之下，所述反射片贴合于所述胶框的底表面上。
进一步地，所述侧面与所述底面之间形成收容槽，所述胶框的底部朝向所述侧面沿伸形成伸出部，所述伸出部对应收容于所述收容槽之中。
进一步地，所述侧面与所述底面之间设置有倾斜面，所述胶框的内侧面与底表面之间设置有斜面，所述斜面与所述倾斜面对应配合。
进一步地，所述倾斜面与所述侧面的夹角为钝角，所述倾斜面与所述底面的夹角为钝角。
进一步地，所述侧面与所述底面之间设置有第一弧面，所述胶框的内侧面与底表面之间设置有第二弧面，所述第一弧面与所述第二弧面对应配合。
进一步地，所述第一弧面朝向所述胶框的内侧面凸起，所述第二弧面朝向所述胶框的外侧面凸起。
进一步地，所述反射片通过双面胶与所述胶框的底表面贴合。
进一步地，所述背光模块还包括：遮光部及若干光学膜片，所述若干光学膜片设置于所述导光板之上，所述遮光部设置于所述若干光学膜片与所述胶框之上。
进一步地，所述遮光部为遮光胶带。
本发明的另一目的还在于提供一种液晶显示器，包括上述的背光模块。
本发明通过将胶框的底部朝向导光板的侧面沿伸，得以增大胶框的底表面的面积，从而使反射片与胶框的底表面的贴合面积增大，进而增加反射片的贴合牢固程度，提高可靠性。
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是根据本发明的液晶显示装置的结构示意图；
图2是根据本发明的第一实施例的背光模块的局部结构示意图；
图3是根据本发明的第二实施例的背光模块的局部结构示意图；
图4是根据本发明的第三实施例的背光模块的局部结构示意图。
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是根据本发明的液晶显示装置的结构示意图。
参照图1，根据本发明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。由于本发明的液晶显示面板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。
以下将利用多个实施例对根据本发明的背光模块100的具体结构进行详细的描述。
<第一实施例>
图2是根据本发明的第一实施例的背光模块的局部结构示意图。
参照图2，根据本发明的第一实施例的背光模块100包括：导光板110、胶框120、反射片130、遮光部140以及若干光学膜片150。
具体而言，导光板110包括侧面111及与该侧面111垂直的底面112。胶框120的底部朝向侧面111沿伸以配合于侧面111与底面112之间，从而使胶框120的底表面121得以扩展，其面积增大。反射片130设置在导光板110和胶框120之下，并且反射片130贴合于胶框120的底表面121上。
如上所述，通过将胶框120的底部朝向导光板110的侧面111沿伸，得以增大胶框120的底表面121的面积，从而使反射片130与胶框120的底表面121的贴合面积增大，进而增加反射片130的贴合牢固程度，提高可靠性。
进一步地，侧面111与底面112之间形成一收容槽113，胶框120的底部朝向侧面111沿伸形成一伸出部122，该伸出部122与该收容槽113匹配，因此，该伸出部122对应容置于该收容槽113中，使底表面121得以向侧面111方向延展，从而增大底表面121的面积。
进一步地，在根据本发明的第一实施例中，优选的，反射片130通过双面胶160贴合于胶框120的底表面121上，其用于将导光板110的底面112出射的光反射回导光板110中。本发明并不限制使用双面胶160，也可例如是其他合适类型的贴合方式将反射片130贴合于胶框120的底表面121上。
此外，若干光学膜片150设置于导光板110之上，用于汇聚由导光板110出射的光，以提高由导光板110出射的光的亮度，并且还能够提升导光板110出射的光的向上亮度，并将导光板110出射的光柔散化，从而向液晶显示面板200提供均匀的面光源。遮光部140设置于这些光学膜片150与胶框120之上，用于遮挡由导光板110与胶框120之间的间隔泄露出的光。在根据本发明的第一实施例中，优选的，遮光部140为遮光胶带，但本发明并不限制于此。
需要说明的是，根据本发明的第一实施例的背光模块100还可包括其他合适类型的光学部件，其可参考现有技术的内容，在此不再赘述。
<第二实施例>
图3是根据本发明的第二实施例的背光模块的局部结构示意图。
参照图3，根据本发明的第二实施例的背光模块100包括：导光板110、胶框120、反射片130、遮光部140以及若干光学膜片150。
具体而言，导光板110包括侧面111及与该侧面111垂直的底面112。胶框120的底部朝向侧面111沿伸以配合于侧面111与底面112之间，从而使胶框120的底表面121得以扩展，其面积增大。反射片130设置在导光板110和胶框120之下，并且反射片130贴合于胶框120的底表面121上。
如上所述，通过将胶框120的底部朝向导光板110的侧面111沿伸，得以增大胶框120的底表面121的面积，从而使反射片130与胶框120的底表面121的贴合面积增大，进而增加反射片130的贴合牢固程度，提高可靠性。
进一步地，侧面111与底面112之间设置一倾斜面114，胶框120的内侧面124与底表面121之间设置有斜面125，该斜面125与该倾斜面114对应配合，使底表面121得以向侧面111方向延展，从而增大底表面121的面积。此外，倾斜面114与侧面111的夹角为钝角，倾斜面114与底面112的夹角为钝角；为了与倾斜面114对应配合，斜面125与内侧面124的夹角为钝角，斜面125与底表面121的夹角为锐角，但本发明并不局限于此。
进一步地，在根据本发明的第二实施例中，优选的，反射片130通过双面胶160贴合于胶框120的底表面121上，其用于将导光板110的底面112出射的光反射回导光板110中。本发明并不限制使用双面胶160，也可例如是其他合适类型的贴合方式将反射片130贴合于胶框120的底表面121上。
此外，若干光学膜片150设置于导光板110之上，用于汇聚由导光板110出射的光，以提高由导光板110出射的光的亮度，并且还能够提升导光板110出射的光的向上亮度，并将导光板110出射的光柔散化，从而向液晶显示面板200提供均匀的面光源。遮光部140设置于这些光学膜片150与胶框120之上，用于遮挡由导光板110与胶框120之间的间隔泄露出的光。在根据本发明的第二实施例中，优选的，遮光部140为遮光胶带，但本发明并不限制于此。
需要说明的是，根据本发明的第二实施例的背光模块100还可包括其他合适类型的光学部件，其可参考现有技术的内容，在此不再赘述。
<第三实施例>
图3是根据本发明的第三实施例的背光模块的局部结构示意图。

具体而言，导光板110包括侧面111及与该侧面111垂直的底面112。胶框120的底部朝向侧面111沿伸以配合于侧面111与底面112之间，从而使胶框120的底表面121得以扩展，其面积增大。反射片130设置在导光板110和胶框120之下，并且反射片130贴合于胶框120的底表面121上。
如上所述，通过将胶框120的底部朝向导光板110的侧面111沿伸，得以 增大胶框120的底表面121的面积，从而使反射片130与胶框120的底表面121的贴合面积增大，进而增加反射片130的贴合牢固程度，提高可靠性。
进一步地，侧面111与底面112之间设置一第一弧面115，胶框120的内侧面124与底表面121之间设置有第二弧面126，该第二弧面126与该第一弧面115对应配合，使底表面121得以向侧面111方向延展，从而增大底表面121的面积。此外，第一弧面115朝向胶框120的内侧面124凸起，第二弧面126朝向胶框120的外侧面123凸起，但本发明并不局限于此。
进一步地，在根据本发明的第三实施例中，优选的，反射片130通过双面胶160贴合于胶框120的底表面121上，其用于将导光板110的底面112出射的光反射回导光板110中。本发明并不限制使用双面胶160，也可例如是其他合适类型的贴合方式将反射片130贴合于胶框120的底表面121上。
此外，若干光学膜片150设置于导光板110之上，用于汇聚由导光板110出射的光，以提高由导光板110出射的光的亮度，并且还能够提升导光板110出射的光的向上亮度，并将导光板110出射的光柔散化，从而向液晶显示面板200提供均匀的面光源。遮光部140设置于这些光学膜片150与胶框120之上，用于遮挡由导光板110与胶框120之间的间隔泄露出的光。在根据本发明的第三实施例中，优选的，遮光部140为遮光胶带，但本发明并不限制于此。
