本发明公开一种液晶显示装置， 包括液晶显示模组， 作为本发明液晶显示 模组的实施例一， 如图 2和图 3所示， 包括前框 1、 中框 2、 背板 3和光源散热 件 4, 所述光源散热件 4固定在背板 3上， 所述中框 2包括一水平壁 21和一垂 直壁 22, 所述光源散热件 4包括一垂直壁 41 , 所述中框 2与光源散热件 4上下 对应， 所述中框 2的垂直壁 22和光源散热件 4的垂直壁 41上对应设置有相互 配合的卡持结构， 更具体的， 所述中框的垂直壁 22上的卡持结构为凸块 221 , 所述光源散热件垂直壁 41上的卡持结构为凹槽 42,所述凸块 221插入所述凹槽 42内。
本发明所述液晶显示模组的中框平面定义为水平面， 与水平面垂直的方向 定义为垂直面。
本发明所述液晶显示模组利用中框 2和光源散热件 4的上下对应关系， 在 中框的垂直壁 22上设置凸块 221 ,所述光源散热件的垂直壁 41上对应设置有凹 槽 42, 所述凸块 221插入所述凹槽 42内， 从而把使中框 2和光源散热件 4在竖 直方向上得到定位， 可增加中框 2 的抗扭转能力， 在承载液晶显示面板时不易 产生变形， 从而很好地起到承载作用。 长度， 相应的， 所述中框上的凸块 221 也可以是完整的长条状； 当然如果所述 凹槽 42为分段式结构， 即光源散热件上的凹槽 42数量为多个， 也是可行的， 相应的， 所述中框上的凸块 221也应该为分段式结构， 并且数量为多个。
在本实施例中， 所述前框 1包括一垂直壁 11 ,所述前框垂直壁 11的内表面 与中框垂直壁 22的外表面贴合， 所述背板 3也包括一垂直壁 31 , 所述前框垂直 壁 11和背板的垂直壁 31上下对齐， 所以液晶显示模组的边框单边又缩窄了一 个前框或背板的壁厚， 从而获得了更窄边框的液晶显示模组。 本发明所述的两 垂直壁上下对齐是指： 其中壁厚稍薄垂直壁的内壁不超出另一垂直壁的内壁， 且外壁也不超出另一垂直壁的外壁。
在本实施例中， 所述中框的水平壁 21 上设有第一挡墙 23 , 所述第一挡墙 23与中框的垂直壁 22平行，第一挡墙 23的外表面与光源散热件垂直壁 41的内 表面贴合， 所述第一挡墙 23和中框 2与光源散热件 4之间的竖直定位结构配合 使用， 可以进一步地增加中框 2的抗扭转能力。
在本实施例中， 如果所述中框垂直壁上的卡持结构为 槽， 所述光源散热 件垂直壁上的卡持结构为凸块， 所述凸块插入所述凹槽内， 同样可以把使中框 和光源散热件在竖直方向上得到定位， 增加中框的抗扭转能力， 获得相近的有 益效果。 作为本发明所述液晶显示模组的实施例二， 如图 4和图 5所示， 与实施例 一不同之处在于所述光源散热件上的凹槽 42为燕尾槽， 所述中框上的凸块上设 有卡扣 222, 所述卡扣 222卡入所述凹槽 42内， 所以中框 2和光源散热件 4在 竖直方向的定位更加可靠， 更好地实现中框 2承载液晶显示面板的功能。
作为本发明所述液晶显示模组的实施例三， 如图 6所示， 与实施例二不同 之处在于所述中框的水平壁 21上设有第二挡墙 24, 所述第二挡墙 24与中框的 垂直壁 22平行， 所述第二挡墙 24的内表面与光源散热件垂直壁 41的外表面贴 合， 所述第二挡墙 24与前框的垂直壁 11上下对齐， 而且所述第二挡墙 24与背 板的垂直壁 31上下对齐， 本实施例依然能保证较窄的边框设计， 另外第二挡墙 24和第一挡墙 23卡住光源散热件 4的内外表面， 使中框 2不能轻易的扭转， 使 中框 2 的抗扭转能力进一步提升， 在承载液晶显示面板时不易产生变形， 从而 很好地起到承载作用。
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， 还可以做出若干筒单推演或替 换， 都应当视为属于本发明的保护范围。
