Description

背光模组及其液晶显示器
技术领域
本发明涉及一种背光模组, 特别是涉及一种利用支架的平面支撑光学板以及利用支架 的凸块定位光学膜片的背光模组及其液晶显示器。 背景技术
请参阅图 1至图 3, 图 1为现有的一种液晶显示器的示意图; 图 2为图 1液晶显示器 其背光模组的圆钢柱受力而使光学板变形或破裂的示意图; 图 3为图 1液晶显示器其背光 模组的光学膜片与圆钢柱为点接触的示意图。
如图 1所示, 液晶显示器 1包含背光模组 10以及液晶显示面板 11。 背光模组 10的背 板结构 100常采用 n型折弯以提高背板强度。 在超大尺寸模组中, 背板结构 100—般采用 铝型材与钣金的组合方式, 在定位光学膜片 101或光学板 102 (例如: 扩散板)时, 由于铝 型材无法采用如钣金背板的冲压翻边的方式成型, 一般采用铆接圆钢柱 103来定位光学膜 片 101或光学板 102。
如图 2所示, 由于圆钢柱 103与其它零件例如光学板 102接触时为点接触, 当振动冲 击时, 光学板 102与圆钢柱 103的接触面积极小, 由于圆钢柱 103的反作用力, 此时光学 板 102将承受最大的压强, 即应力集中, 光学板 102将会变形乃至破裂 (如图 2的波浪线 所示); 如图 3所示, 光学膜片 101通过圆钢柱 103悬挂, 接触面也为点接触, 由于光学 膜片 101为悬挂方式, 且光学膜片 101为片状薄膜, 片状薄膜当一点受力时, 在重力作用 下, 以受力点为中心点, 产生两个角度分力(如图 3的箭头符号所示), 即片状薄膜无法在 只有一个支点时平衡放置, 因此将产生悬挂翘曲变形, 造成模组画面为亮暗不均。
另外, 由于采用铆接圆钢柱 103, 为获得较高的强度, 圆钢柱 103不可太小, 同时还 需提供足够的空间放置圆钢柱 103的底部以及铆接冲压空间, 不利于缩小模组边框。 发明内容

以下结合附图所示的最佳实施例作进一步详述。
请参阅图 4与图 5, 图 4为本发明一实施例运用有支架的背光模组的液晶显示器的示 意图; 图 5为图 4背光模组所运用的支架的示意图。
如图 4所示, 液晶显示器 2包括背光模组 20以及配置在背光模组 20旁的液晶显示面 板 21。 背光模组 20包括背板 200。 背板 200具有至少一侧。 于此实施例中, 此至少一侧 以背板 200具有第一侧 200a与第二侧 200b作说明, 但不限定于此。 背光模组 20具有背光单元 201, 背光单元 201包括有光学板 202与光学膜片 203。 值 得一提的是, 由于此实施例的背光模组 20为直下式背光模组, 因此光学板 202 以扩散板 为例。 当然, 若背光模组 20为侧光式背光模组, 则光学板 202为导光板。 换言之, 本案 的实施例所提及的支架 (第一支架 204或第二支架 205)能够被运用在直下式背光模组或侧 光式背光模组, 以作为光学板 202或光学膜片 203的定位结构。
第一侧 200a具有第一表面 S 1 ; 第二侧 200b具有第二表面 S2。 第一表面 S I配置有第 一支架 204; 或者, 第二表面 S2配置有第二支架 205。
具体而言, 第一支架 204 (或第二支架 205)如图 5所示 (其中, 由于第一支架 204与第 二支架 205的结构能够为相同, 于此仅绘示第一支架 204作说明)。
如图 5所示, 第一支架 204包括第一水平部 204a以及由第一水平部 204a所延伸的第 一垂直部 204b。 第一垂直部 204b包括第一平面 204c与第一凸块 204d。
第二支架 205亦能够包括第二水平部 205a以及由第二水平部 205a所延伸的第二垂直 部 205b。 第二垂直部 205b包括第二平面 205c与第二凸块 (关于第二凸块请参考图 5中的 第一凸块 204d即可)。
请参阅图 图 7所示, 图 6为利用图 4支架支撑光学板的示意图; 图 7为利用图 4支 架定位光学膜片的示意图。
第一支架 204的第一平面 204c或第二支架 205的第二平面 205c能够用以支撑光学板 202 (如图 4与图 6所示。 其中于图 6中, 仅绘示第一平面 204c支撑光学板 202作说明); 第一支架 204的第一凸块 204d或第二支架 205的第二凸块 (关于第二凸块请参考图 5中的 第一凸块 204d)能够用以定位光学膜片 203 (如图 4、 图 5与图 7所示。 其中于图 7中, 仅 绘示第一凸块 204d定位光学膜片 203作说明)。
如图 4所示, 支架 (第一支架 204与第二支架 205)能够为钣金冲压方式成型或是塑料 成型。 第一水平部 204a定位于第一表面 S 1 ; 第二水平部 205a定位于第二表面 S2。 例如, 背板 200的第一表面 S 1与第二表面 S2能够钻有螺纹孔,第一支架 204的第一水平部 204a 与第二支架 205的第二水平部 205a通过螺丝件 206锁附方式分别定位于铝型材背板 200 的第一表面 S 1与第二表面 S2上。 或者, 若支架为钣金冲压方式成型时, 第一水平部 204a 与第二水平部 205a能够通过焊接方式而分别定位于第一表面 S I与第二表面 S2。然而, 上 述支架固定于第一表面 S 1与第二表面 S2的方式仅为说明以利理解, 其并不限定于此。
如图 4所示,第一水平部 204a与第二水平部 205a分别放置于背板 200 (如: 铝型材) 的第一侧 200a与第二侧 200b的第一表面 S 1与第二表面 S2上。 第一表面 S 1与第二表面 S2用于承载光学板 202, 光学板 202上方放置光学膜片 203。 第一支架 204的第一垂直部 204b与第二支架 205的第二垂直部 205b用于支撑光学板 202。 其中, 利用第一垂直部 204b的第一平面 204c与第二垂直部 205b的第二平面 205c, 可均勾承担光学板 202的振动冲击,使光学板 202能均勾受力。较佳地,在第一垂直部 204b 与第二垂直部 205b 能够成型多个凸包, 以避免第一垂直部或第二垂直部本身的弯曲不平 整或锁附不平整, 造成垂直部接触光学板 202的部位不确定。
如图 7所示, 光学膜片 203包含多数个通孔 203a并悬挂于第一凸块 204d与第二凸块 (关于第二凸块请参考图 5中的第一凸块 204d) ,由于第一凸块 204d与第二凸块具有一平面 P, 使得光学膜片 203 能够均勾受力, 且受力方向与重力在一竖直面上, 从而不会产生角 度分力, 不会出现翘曲不良。
请参阅图 8, 图 8为图 4背光模组所运用的支架另一实施例的示意图。
如图 8所示,第一支架 204的第一凸块 204d (或第二支架 205的第二凸块)能够为中间 高两边低。 支架为钣金冲压或塑料成型, 厚度较薄, 比用圆形铆柱薄, 更有利于缩小模组 边框宽度。
综合以上, 本发明实施例所揭露的背光模组及其液晶显示器, 具有以下的有益效果: 1.利用第一支架的第一平面或第二支架的第二平面支撑光学板, 并利用第一凸块或第 二凸块定位光学膜片, 以提升光学板与光学膜片的定位强度。
2. 支架 (第一支架或第二支架)能够为钣金冲压或塑料成型, 厚度较薄, 比用圆形铆 柱薄, 更有利于缩小模组边框宽度。
以上, 仅为本发明的较佳实施例, 意在进一步说明本发明, 而非对其进行限定。 凡根 据上述的文字和附图所公开的内容进行的简单的替换, 都在本专利的权利保护范围之列。
