【附图说明】
图 1是现有的一种液晶显示装置示意图;
图 2是本发明实施例的液晶显示装置示意图;
其中: 100、 前框; 200、 中框; 210、 承接部; 220、 緩沖部; 230、 凹槽; 300、 面板; 400、 光学膜片; 500、 导光板; 600、 灯条; 610、 导热胶带; 700、 背板; 710、 折边; 800、 铆柱。
【具体实施方式】
下面结合附图和较佳的实施例对本发明作进一步说明。
如图 2所示, 其包括面板 300和背光模组, 面板 300和背光模组通过前框 100进行固定。 背光模组包括由中框 200和背板 700组成的框体, 背板 700上承 托有导光板 500, 导光板 500的出光面覆有光学膜片 400。 背板 700四周有折边 710, 在导光板 500入光面对应的折边 710位置设有光源组件, 光源组件可以选 用 LED灯条 600。 背板 700的四周固定有上述的一种液晶显示装置的中框 200, 中框 200设有一延伸部分, 间隔在面板 300和导光板 500之间。
中框 200呈矩形,其与液晶显示装置入光侧对应的一条设有 7 接部 210,与 液晶显示装置非入光侧对应另外三条边设有緩沖部 220;承接部 210采用塑胶等
硬性材料, 緩沖部 220采用柔性材料。
导光板 500的边缘抵住中框 200的緩沖部 220,緩沖部 220的多条边对导光 板 500形成夹持作用, 实现导光板 500的定位, 而且緩沖部 220采用柔性材料, 在撞击、 晃动过程中对导光板 500起到很好的保护作用。
中框 200的緩沖部 220底部设有供背板 700的折边 710嵌入的凹槽 230,背 板 700的折边 710嵌入凹槽 230后, 棵露在外面的是緩沖部 220凹槽 230的两 个槽壁, 位于背板 700内侧的一个槽壁可以用来定位导光板 500, 另一个槽壁可 用于固定液晶显示装置的前框 100, 只要一种定位结构就可以实现多种功能。
进一步的, 所述柔性材料为发泡材料; 发泡材料密度低, 重量轻, 緩沖性 能好, 有利于液晶显示装置的轻薄化。
中框 200的承接部 210和緩沖部 220可以一体成型, 这样可以省略后续的 组装步骤, 降低生产成本。 当然承接部 210、 緩沖部 220也可以拼接固定, 可以 筒化中框 200 的模具结构, 降低开模成本和缩短模具制造的周期。 同样的, 緩 沖部 220 的三条边可以一体成型, 也可以采用采用粘贴、 卡接、 铆接或螺丝固 定等方式固定。 优选分体拼接固定的方式, 可以筒化中框 200 的模具结构, 降 低开模成本和缩短模具制造的周期。 另外, 每条边只需要跟液晶显示装置的背 板 700固定即可, 固定方式也比较筒单, 可以提高生产效率。
本发明由于将中框 200分为承接部 210和緩沖部 220两部分, 非入光侧采 用发泡材料中框, 弹性优良, 有很好的緩沖作用, 放置在导光板和后盖之间, 组装时使导光板和中框紧配合, 这样在导光板受热或受潮膨胀的时候, 中框可 以吸收导光板的膨胀量; 待外部环境恢复正常时, 中框的弹性作用又可以使得 导光板恢复原位。 而且采用这样的发泡材料中框, 就可以拿掉铆柱, 导光板就 不用裁切加工, 也就不会出现光学品味问题, 更容易实现窄边框设计。 在入光 侧采用塑料中框, 保持拼接后整个中框的平整度。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明, 不 能认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通
技术人员来说, 在不脱离本发明构思的前提下, 还可以做出若千筒单推演或替 换, 都应当视为属于本发明的保护范围。
