在 T文中将基于实施倒并参考 ^图来对本发明迸行更详细的描述。 其中； 图 1是根据本发明的背:光模块的第一表面的视图；
图 2是根据本发明的背光模块的第二表面的视图；
图 3是图 2中的 I部分的放大视图；
图 4是根据本发明的拆卸构件的结构示意图；
图 5是装配了膜片支撑件的背光模块的示意图；
图 6是装配了光学膜片的背光模块的结构示意图；
图 7是向膜片支撑件上装配液晶组件的示意图；
图 8是向膜片支撑件上装配液晶组件的另一示意图；
图 9是根据本发明的拼接液晶面板的示意图。
在^图中，相同的部件使用相同的附图标记。附图并未按照实际的比例绘制。 具体实施方式
下面将结合^图对本发明做进一步说明。
如图〗所示， 背光模块 10包括背板 11。在背板 11的第 ·表面上设置有光源 灯 12。 在一个实施例中， 光源灯 12可选择为普通荧光灯、 冷阴极灯管或发光二 极管（即 LED)。光源灯 12与背板 11之间的连接是本领域的技术人员所熟知的， 这里不再赘述。
如图 2所示， 背光模块 10还包括包围背板 i i的边缘的承载框 13和连接在 承载框 13和背板 11的第二表面之间的拆卸构件 20。在图 2所示的实施^中， 共 设置有四个拆卸构件 20, 并且分成两对， 其中一对处于背板 i i的一个侧边处， 另一对处于背板 U的相对的侧边处。 如图 3和 4所示， 拆卸钩件 20包括与承载 框 13相连的第一连接体 21和与背板 11相连第二连接体 22 ,第一连接体 21和第 二连接体 22为铰链连接， 从整体来看拆卸构件 20为合页状。 在一个实施例中， 第一连接体 21和第二连接体 22均通过螺钉与承载框 B或背板 11相连， 以便于 拆卸。 这种合页状的拆卸构件 20的优点将在下文中详细描述。
如图 5所示， 背光模块 10还包括固定设置在承载框的边缘还固定设置有胶 框 70。 装配在背板 11的第一表面侧， 并且与胶框 70固定连接的膜 j†支撑件 30。 膜片支撑件 30由纵橫交错的支杆 31、 32形成， 从而在将膜片支撑件 30装配到 背板 11的第一表面上之后， 会将背板 i i的第一表面分隔成多个间隔 33。这些间 隔 33 ]¾于安装液晶组件， 这将在下文中详细描述。 还应注意地是， 在膜片支撑 件 30与背板 1 1 接触的部分上设置有槽 （未示出） ， 灯管式的光源灯 12能穿过 这些槽， 方便了膜片支撑件 30的装配。
如图 6所示， 背光模块 10还包括装配在每 ·个间隔 33中的光学膜片 40。在 个实施例中， 光学膜片 40包括扩散片、 棱镜片、 光学补偿膜等， 这些元件均 是本领域的技术人员所熟知的， 这里不再赘述。 总体来说， 背光模块 10 的背板
1 1通过拆卸构件 20与承载框 13相连， 承载框 13与胶框 70固定连接， 而膜 j†支 撑件 30与胶框 70固定连接， 光学部材 40装配在膜支撑件 30上。
最后， 在膜片支撑件 30上， 光学部材 40的外侧安装有多个液晶组件 50。 应 注意地是， 多个液晶组件 50的每一个与第一表面的相应的间隔 33对齐。 这样就 形成了包括背光模块 10和液晶组件 50的拼接式液晶面板 60, 如图 9所示。这样 就实现了多台液晶模组共用一片背光模块 10,降低了生产成本。在一个实施^中， 为了使液晶组件 50与背光模块 10固定连接， 还使用了前框 61将液晶组件 50与 背光模块 10固定在一起。
在这种拼接式液晶面板 60中， 液晶组件 50并没有与背板 11直接相连， 而 是设置在膜片支撑件 30上， 与背板 1】 间隔 ·定的距离， 即液晶组件 50和背光 模组 10形成独立的模块。当背板 n出现故障时，可将其中一对拆卸构件拆卸掉， 由于拆卸构件 20为合页状， 因此可以像打开门一样打开背板 1 对其进行检测而 不需要拆卸液晶组件 50。 当需要维修或更换背板 i i时， 将所有的拆卸构件 20拆 卸 T来即可将背板 i i取下， 而无需拆卸液晶组件 50。 这大大方便了拼接式液晶 面板 60的维护。
下面根据图 1到 9来描述拼接式液晶面板 60的装配过程。
首先， 在背板 U的第一表面上设置多个光源灯 12, 如图 1所示。 接着， 在 背板 1 的周围设置承载框 13。 之后， 安装拆卸构件 20, 其中拆卸构件 20的第 连接体 21与承载框 13相连， 第二连接体 22与背板 11的第二表面相连， 如图 2所示。 在背板 1 1的第 ·表面侧、 光源灯】2的外侧固定设置膜片支撑件 30, 膜 片支撑件 30将背板 11的第一表面侧分隔成多个间隔 33 , 如图 5所示。在膜片支 撑件 30上固定设置光学部材 40， 从而形成一片背光模块 10， 如图 6所示。最后， 将多个液晶组件 50安装于膜 j†支撑件 30」：:、 光学部材 40的外侧形成拼接式液 晶面板 60， 如图 9所示。
在一个实施例中， 可将每一个液晶组件 50分别安装到间隔 33处， 如图 7所 示。 在另一个实施 ^中， 也可以首先将多个液晶组件拼接成一个整体 51 , 然后与 背光模块】0装配在一起。 为了使液晶组件 50与背光模块 10固定连接， 还使用 了前框 61将液晶组件 50与背光模块】0固定在一起。
尽管没有以图示显示， 根据本发明的拼接式液晶面板 60 还可用于拼接式电 视。 这种拼接式电视同样具有成本低、 易于维护的优点。
虽然已经参考优选实施例对本发明进行了描述， 但在不脱离本发明的范围 的情况 T， 可以对其进行各种改进并且可以用等效物替换其中的部件。 尤其是， 只要不存在结构冲突， 各个实施倒中所提到的各项技术特征均可以任意方式组合 起来。 本发明并不局限于文中公开的特定实施倒， 而是包括落入权利要求的范圈 內的所有技术方案。
