Description

液晶显示装置用的侧框压条 技术领域
本发明涉及一种液晶显示装置用的侧框压条， 特别是涉及一种具有 Π字型结构的侧框压条， 其设有多个嵌合元件， 以与液晶显示装置所用 的支承框架嵌合并固定。 背景技术
随着半导体技术的快速发展， 各种电子显示装置要求尽量达到轻、 薄、 短、 小等要求。 尤其是平面型显示装置例如液晶显示器、 电浆显示 器等， 更要求解析度高、 轻、 薄等。 据此, 业界无不致力于尽量减少不 必要的组装元件。
目前液晶显示装置已广泛用于桌上型电脑及笔记本型电脑。 而构成 液晶显示装置的液晶显示板模块及背光模块则通过不同的组装过程分别 组装， 随后再使这些模块彼此组装在一起。 现有的背光模块利用一呈口 型的上框架与支承框架将液晶显示装置的元件如反射板、 导光板、 扩散 膜及灯管模块组合在一起， 如图 1所示。 但由于液晶显示装置讲究轻、 薄， 使上述口型上框架必须做得更薄， 从而造成上框架结构太软， 注射 成型较不易，且整体结构较复杂。为了改善制造工艺，美国专利 6,502,945 B2公开一种堆叠背光模块及其组装方法。 该专利所公开的堆叠背光模块 包括一支承框架、 一反射板、 放置在该反射板上的导光板、 放置在该导 光板两侧的一对灯管组件、放置在该导光板上的扩散片以及一对上边框。 这些上边框可覆盖上述导光板边缘并可与上述支承框架彼此嵌合固定。
上述美国专利主要利用一 L型上边框及支承框架作为支撑结构并用 以组合其他元件。 该 L型上边框为了支撑上述堆叠型背光模块， 其边宽 无法做得太小， 否则无法坚固地固持上述堆叠型背光模块。 相对地， 将 损失上述堆叠型背光模块的开口率， 即需要牺牲显示器的可视面积。 因 此， 仍需要一种使上边框的边宽变得较小但仍可,稳固地固持上述堆叠型 背光模块的组装方法。 上述使上边框的边框变小的过程在本申请中称为 "窄边化"。
此外， 为了节省上边框所用的材料， 期望以较小的成本完成背光模 块的组装， 因此另外提出一种呈 "一"字型的上框架， 在该 "一"字型 上框架内设有一凹槽， 以供容纳液晶显示板模块以及背光模块等， 并利 用设在该上 f匡架边缘上的嵌合元件与支承框架嵌合并固定。 这些 "一" 字型的上框架借助所设凹槽及边缘所设有的嵌合元件的作用予以固定。 这种 "一"字型上边框虽相对于现有口字型上边框可达到更节省原料的 目的， 但为实现良好固定， 框架本身的边宽无法做得太小， 否则将无法 发挥其固定作用。 尤其在面板尺寸要求越来越大的情况下， 这些 "一" 字型上边框通过凹槽嵌合力所获得的固定效果较差， 可承受的外界力矩 所施加的抵抗力变小， 并容易造成框架本身脱离。 据此， 这种 "一"字 型上边框的固持力仍不足且无法使液晶显示装置的可视区维持如传统 "口型"上 ¾框一样的大小。
基于上述现有技术的缺点， 本发明人对液晶显示装置结构进行了广 泛研究， 并因而完成了本发明。 发明内容
本发明的主要目的在于提供一种液晶显示装置用的侧框压条， 其中 该侧框压条具有 π字型结构， 且该侧框压条上设有多个嵌合元件， 用以 与液晶显示装置所用的支承框架嵌合并固定。
本发明的液晶显示装置用的侧框压条由于具有 " Π "字型结构， 因 此通过压条上所设置的嵌合元件与液晶显示装置所用的支承框架嵌合， 可达到传统禾 ϋ用口型上边框所能达到的固定强度。 此外， 根据本发明的液晶显示装置用的侧框压条， 所需上胶框的材 料量可相对降低， 甚至降低至一半以上， 因此具有可节省注射塑胶材料 的优点， 并可大幅缩短上胶框模制时的饱模时间， 并可达到降低成本的 要求。
再者， 使用本发明的液晶显示装置用的侧框压条， 仅需在支承框架 相对两侧设置该侧框压条即可达到固定目的， 从而具有简化组装过程的 效果。 '
此外， 本发明的液晶显示装置用的侧框压条利用三点固定的理论即 可达到固定目的， 因而可使该侧框压条制成边宽较窄从而有助于增加可 视区。 因此， 与 "一" 字型的侧胶框相比， 本发明的侧框压条可增进液 晶显示装置的可视区。
根据本发明的液晶显示装置用的侧框压条可与现有支承框架的结构 嵌合组装， 因此可在不改变现有的支承框架结构的情况下使用， 不需改 变既有液晶显示装置的组装过程， 即可同时达到组装容易、 坚固固定、 节省饱模时间以及节省材料和高开口率的目的。 附图说明
图 1为现有技术的背光模块的口型上框架与支承框架的分解图； 图 2为本发明的液晶显示装置用的侧框压条与液晶显示装置的支承 框架在未组合时的示意图；
图 3为本发明的液晶显示装置用的侧框压条的概视图；
图 4为本发明的液晶显示装置用的侧框压条的前视图； 以及 图 5为本发明的液晶显示装置用的侧框压条的后视图。 具体实施方式
本发明的上述目的及其他目的将通过以下结合附图对较佳具体实施 例的详细说明变得更显而易见。
图 2为本发明的液晶显示装置用的侧框压条 1与液晶显示装置的支 承框架在未组合时的示意图。 图 3示出了本发明的液晶显示装置用的侧 框压条 1的概视图。 由图 3可以看出， 本发明的液晶显示装置用的侧框 压条 1主要由一压条本体 11以及一对延伸部 12所构成。 该压条本体 11 与该对延伸部 12构成一 " Π "字塑， 而在压条本体 11上设有多个嵌合 元件 13、 14, 同时在该对延伸部 12的端部处也分别设有至少一个嵌合元 件 13。压条本体 11上所设的嵌合元件的数量并无限制，只要对应于液晶 显示装置的支承框架上的嵌合元件 21或 22处设有的嵌合元件即可。 然 而， 根据力学理论， 本发明的液晶显示装置用的侧框压条 1只要在两端 延伸部 12各设有一个嵌合元件 13， 再配合压条本体 11上的一个嵌合元 件 13或 14即可达到所欲固定的目的。 据此， 设在压条本体 11上的嵌合 元件数可为一或多个。 然而， 本发明的液晶显示装置用的侧框压条 1仅 在支承框架的一侧设置也可达到固定目的。
图 4以及图 5分别示出了本发明的液晶显示装置用的侧框压条 1的 前视图及后视图。 本发明所显示的附图中， 仅以嵌合元件数为 7个加以 表示， 但本发明并不限于这些数量， 其可多于 7个也可少于 7个， 只要 可达到本发明所欲达到的固定目的即可。
本发明的液晶显示装置用的侧框压条 1所具有的两边延伸部 12的长 度可彼此相同或不同， 其长度并无特别限制， 只要能达到本发明所欲实 现的固定目的即可。 该侧框压条 1可利用塑胶材料以模制成形等方法制 造。
根据本发明附图所显示的侧框压条以及支承框架所设嵌合元件为卡 勾与凹勾形式而可互相嵌合。 这些嵌合元件除了本发明说明书所示的形 式之外， 还可设计为凹点与凸点， 或任何其他形式， 只要可达到互相嵌 合的目的即可。 此外， 本发明的侧 f匡压条 1上所设的嵌合元件 13、 14彼 此可设计成 同形状， 只要与欲组合的支承框架所对应的嵌合元件 21或 22可呈公母形式而可互相嵌合即可。
与传统口型上胶框的固定方式相比， 本发明的液晶显示装置用的侧 框压条 1 由于仅需在支承框架的相对两侧设置即可达到传统口型上胶框 所欲达到的囡定强度， 因此可减少制作压条所需的材料并进而降低成本。
此外，柩据本发明的液晶显示装置用的侧框压条 1， 由于其尺寸与口 型上胶框相 [：匕较小， 从而可大幅縮短上胶框模制时的饱模时间， 并可达 到降低成本 ^要求。
再者， 使用本发明的液晶显示装置用的侧框压条 1，仅需在支承框架 相对两侧分另 ϋ设置一侧框压条 1 即可达到固定目的， 从而具有简化组装 过程的目的。
此外，本发明的液晶显示装置用的侧框压条 1因其延伸部 12的设计， 使得侧框压条 1可利用三点固定的理论即可达到良好的固定目的， 因此 压条本体 11白勺边宽可设计得更窄（即本发明中所称的 "窄化" 目的）， 从 而有助于增力口可视区。 因此， 与 "一"字型的侧胶才医相比， 本发明的侧 框压条 1可増进液晶显示装置的可视区。
本发明已借助上述较佳具体实施例进行了详细描述， 但本发明并不 限于这些较佳具体实施例， 凡熟知本技术者在不脱离本发明所述的精神 及范围内可^≡出各种变化、 改良及修饰。 这些变化、 改良以及修饰均属 于本发明的 围内。 附图标记说嗎
