Description

便于更换发光二极管灯条的背板结构及其液晶显示器
技术领域
本发明涉及液晶显示装置的制造工艺，特别是涉及便于更换发光二极管灯条的背板结 构的制造工艺。 背景技术
背光模组（back light unit)为液晶显示器（liquid crystal display, LCD)的关键零 组件之一， 由于液晶面板 (LCD panel)本身不具发光的能力， 背光模组的功能即在于供应 充足的亮度与分布均匀的光源，使液晶显示器能正常显示影像。 目前液晶显示器已广泛应 用于监视器、笔记型计算机、数字相机及投影机等具成长潜力的电子产品， 因此带动背光 模组及其相关零组件的需求持续成长。 由于发光二极管具有体积小、 寿命长、 耗电量低、 反应时间短及耐震性强等特性， 已广泛被运用在照明或是背光源上， 取代传统钨丝灯泡、 日光灯管或冷阴极管等传统光源元件。
上述的背光模组， 大多是于一导光板的两侧横向以遮光带包覆发光二极管 （LED) 灯 条与发光二极管（LED)灯条的线材， 以供固定发光二极管（LED)灯条与线材， 而导光板 之后侧再设置有一反光板， 以助于发光二极管 （LED) 灯源将光线往前侧集中。 然而， 上 述的导光板在实际使用的时候会有下列缺失： 上述的导光板在发光二极管 （LED) 灯条里 灌入封装剂的时候， 将使得发光二极管 （LED) 灯条和导光板密合， 如需更换发光二极管 (LED) 灯条时， 导光板的出光条件将被破坏而发光二极管 （LED) 灯条也将被破坏变形， 难以维修使用， 导致成本的增加。 此外， 在发光二极管 （LED) 灯条出现死灯等需要更换 的状况时， 必须从上往下拆卸整个背板模组.浪费返修工时和人力， 且效率低下， 一体成 形的镀锌铜板 （SECC) 背板 +铝挤型材价格总体较贵， 不利于降低成本。 发明内容
本发明要解决的技术问题在于克服上述现有技术的不足，而提出一种便于更换发光二 极管灯条的背板结构及其液晶显示器可以借由活动式的背板在更换发光二极管灯条时，免 去拆下整个背光模组的工时，直接拆下活动式的背板更换灯条即可，从而达到降低制造成 本的目的。
本发明解决上述技术问题采用的技术方案包括，提出一种便于更换发光二极管灯条的 背板结构及其液晶显示器， 包括： 数个锁固件， 一固定式金属背板设置有数个螺纹柱， 以 及一活动式金属背板，包括数个凸块及数个槽孔，该数个凸块位于活动式金属背板的侧边 并设置于相对液晶显示器的一边框结构的开孔， 使该数个凸块插入于该边框结构的开孔， 该数个槽孔则对应该数个螺纹柱，使该数个螺纹柱穿设于该数个槽孔，并透过该数个锁固 件锁固结合固定式金属背板与活动式金属背板。
在本发明一实施例中， 上述固定式金属背板为镀锌铜板 （SECC)。
在本发明一实施例中， 上述活动式金属背板为铝挤型材。
在本发明一实施例中， 上述活动式金属背板上设置一发光灯条。
在本发明一实施例中， 上述该数个槽孔为跑马道槽。
与现有技术相比， 本发明透过背光模组的背板由几部分组成，在靠近灯源侧采用铝挤 型材代替镀锌铜板 （SECC ) 背板.远离灯源侧采用强度高价格便宜的材料如镀锌铜板
( SECC)。 该铝挤型材通过螺母 (SCREW)与中间无光源背板底面锁附在一起，方便拆卸发光 二极管 （LED ) 灯条锁附在铝挤型材上， 然后一起从模组背后插入模组， 并与边框结构
(Frame )及挡板 (Bezel)侧边的开口卡紧定位，灯源同端的挡板 (Bezel)在背板端长出一支 撑部， 插入铝挤开口处， 增加模组结构强度。 附图说明

以下结合附图所示的最佳实施例作进一步详述。
参见图 1以及图 2， 本发明提出一种液晶显示器的背板结构， 包括： 数个锁固件 110， 一镀锌铜板 （SECC) 背板 120设置有数个螺纹柱 121， 以及一铝挤型材背板 130， 包括数 个跑马道槽 131及数个凸块 132，该数个凸块 132位于铝挤型材背板 130的侧边并设置于 相对液晶显示器 100的一边框结构 （Frame ) 101及一挡板 (Bezel) 102的开孔 103， 使该 数个凸块 132插入于边框结构 101 (Frame ) 及挡板（Bezel) 102的开孔 103， 该数个跑马 道槽 131， 则对应该数个螺纹柱 121， 使该数个螺纹柱 121穿设于该数个跑马道槽 131， 并透过该数个锁固件 110锁固结合固定式金属背板 120与铝挤型材背板 130。
本发明的特征在于将一体镀锌铜板 （SECC) 背板分成两部分： 镀锌铜板 （SECC) 背 板 120和铝挤型材背板 130，在结合处将镀锌铜板 ( SECC)背板 120上铆一排外螺纹柱 121， 头朝下方。 铝挤型材背板 130结合处对应位置冲一排跑马道槽 131， 将发光二极管（LED) 灯条 140和铝挤型材背板 130贴附好后， 以锁固件 110， 较佳为螺母， 锁附在螺纹柱 121 上来结合镀锌铜板 （SECC) 背板 120和铝挤型材背板 130， 结合处细部如图 2所示。
铝挤型材背板 130上的发光二极管（LED)灯条 140有相对设置于铝挤型材背板 130 上的若干凸块 132， 边框结构 101 (Frame )及挡板 (Bezel) 102与对应位置开配合凸块 132 的数个开孔 103，以扣紧凸块 132， 借此拉住铝挤型材背板 130。 此外， 铝挤型材背板 130 在靠近灯源底部位置开若干小孔 (或整条槽）， 且同侧的挡板 (Bezel)设置支撑臂， 插入铝 挤型材背板 130的灯源底部若干小孔 (或整条槽）中，以加强铝挤型材背板 130整体的结构 强度。
锁好发光二极管（LED)灯条 140后的铝挤型材背板 130可以从液晶显示器 100的背 光模组下方往上插入液晶显示器 100中， 当铝挤型材背板 130和镀锌铜板 （SECC) 背板 120接触后， 再通过跑马道槽 131往右移动到底， 使得铝挤型材背板 130的若干凸块 132 插入边框结构 101 (Frame )及挡板 (Bezel) 102的开孔 103中， 挡板 (Bezel) 102的支撑臂 插入铝挤型材背板 130上发光二极管 （LED) 灯条 140底部的若干小孔 (或整条槽)后， 利 用锁固件 （螺母） 110将铝挤型材背板 130锁附定位好。
参见图 3、 图 4以及图 5当发光二极管 （LED) 灯条 140损坏或需要返修 （Rework) 时， 先依照安装的方向， 将铝挤型材背板 130的凸块 132向内推挤， 使凸块 132脱离边框 结构 101 (Frame )及挡板 (Bezel) 102的开孔 103 (如图 3所示）， 同时，铝挤型材背板 130 会向另一边位移， 使跑马道槽 131位移 （如图 4所示）， 此时， 将锁固件 （螺母） 110松 脱并脱离螺纹柱 131， 使铝挤型材背板 130脱离液晶显示器 100 (如图 5所示）， 藉此， 可 使更换发光二极管 （LED) 灯条 140迅速拆卸， 以达到更高效便捷的目的。
以上， 仅为本发明之较佳实施例， 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。
