在本实施例中,光学膜片 16设置于导光板 13的靠近液晶面板 11的一侧上。 緩冲件 18抵触光学膜片 16的端部, 以对光学膜片 16进行定位。 在其他实施例 中, 緩冲件 18可将光学膜片 16压制于导光板 13上, 进而对光学膜片 16进行 定位。 在其他实施例中, 光学膜片 16 可以通过其他固定结构固定于导光板 13 上, 例如通过与导光板 13—体成型的定位柱或定位框等定位结构。 光学膜片 16 可以是本领域公知的扩散片、 增亮片或光学补偿片等光学膜片的一种或任意组 合。
在本实施例中, 第二支撑壁 124的靠近液晶面板 11的一侧上设置有反射层 (图未示)。 在优选实施例中, 反射层为反射涂层或反射片。 此外, 还可以通过 第二支撑壁 124的靠近液晶面板 11的一侧进行抛光处理来实现反射效果。
在本实施例中, 光源 14设置于第一侧壁 121与第二侧壁 122所定义的容置 空间中,以使光源 14产生的光线经第一侧壁 121上的通孔 1211进入导光板 13。 具体来说,光源 14包括光源基板 141 以及设置于光源基板 141上的发光体 142。 发光体 142 可以是多颗发光二极管 (LED )或其他光源。 其中, 可通过设置第 一侧壁 121的厚度来控制光源 14与导光板 13的光耦合距离。
在本实施例中, 散热板 17包括彼此连接的第五侧壁 171和第六侧壁 172。 其中, 第五侧壁 171沿着第二方向延伸并且设置于后壳 12的第一侧壁 121与第 二侧壁 122所定义的容置空间中。 光源基板 141通过粘贴或其他适当方式固定 于第五侧壁 171上。 第六侧壁 172沿着第一方向延伸, 并通过螺钉 192固定于 第二支撑壁 124的远离液晶面板 11的一侧上。 在本实施例中, 第二支撑壁 124 的远离液晶面板 11的一侧进一步设置有用于收容第六侧壁 172的凹陷部 1241 , 使得第六侧壁 172的远离液晶面板 11的一侧和第二支撑壁 124的远离液晶面板 11的一侧处于同一水平面上。 值得注意的是, 在本实施例中, 通过散热板 17固 定光源 14,并将光源 14设置于第一侧壁 121与第二侧壁 122所定义的容置空间 中, 但在其他实施例中, 完全通过其他方式来固定光源 14。 例如, 在第一侧壁 121和第二侧壁 122设置适当的支撑结构, 并将光源 14固定于可相对上述支撑 结构滑动的抽取支架上。
在液晶显示装置 10的具体组装过程中, 首先将光源 14的光源基板 141 固 定于散热板 17的第五侧壁 171上, 进一步将光源 14和第五侧壁 171设置于后 壳 12的第一侧壁 121与第二侧壁 122所定义的容置空间中。 随后, 将第六侧壁 172通过螺钉 192或其他适当方式固定于后壳 12的第二支撑壁 124的凹陷部 1241内, 使得散热板 17和光源 14固定于后壳 12上。 随后, 将导光板 13支撑 于第二支撑壁 124上, 并在导光板 13上设置緩冲件 18以及光学膜片 16。 随后, 将液晶面板 11支撑于第一支撑壁 123以及緩冲件 18上。 最后, 将前框 15的第 三侧壁 151压制于液晶面板 11上, 将第四侧壁 152通过螺钉 191或其他适当方 式固定于第二侧壁 122上。
通过上述方式, 本发明的液晶显示装置中的后壳可替代现有技术的液晶显 示装置中的金属背板以及塑胶中框, 降低液晶显示装置的复杂度及生产成本, 进而简化液晶显示装置的组装工序, 并且提高生产厂家的竟争力。
值得注意的是, 图 1仅显示了液晶显示装置 10的一个端部的剖面示意图, 本领域技术人员完全可以理解, 在液晶显示装置 10的其他端部也釆用相同的设 计, 以实现两侧或多侧入光。
以上所述仅为本发明的实施例, 并非因此限制本发明的专利范围, 凡是利 用本发明说明书及附图内容所作的等效结构或等效流程变换, 或直接或间接运 用在其他相关的技术领域, 均同理包括在本发明的专利保护范围内。
