为使本发明实施例的目的、 技术方案和优点更加清楚， 下面将结合本发 明实施例的附图，对本发明实施例的技术方案进行清楚、 完整地描述。显然， 所描述的实施例是本发明的一部分实施例， 而不是全部的实施例。 基于所描 述的本发明的实施例， 本领域普通技术人员在无需创造性劳动的前提下所获 得的所有其他实施例， 都属于本发明保护的范围。
本发明实施例提供了一种液晶显示器， 包括液晶面板 1、 背光源 2以及 金属边框 3 , 其中液晶面板 1扣在背光源 2上， 且在液晶显示器的竖直摆放 状态下， 液晶面板 1悬挂在背光源 2上。
这样使得液晶面板 1处于自然下垂状态， 可以通过背光源 2来承受液晶 面板 1的重力， 使液晶面板 1 (尤其是较大尺寸的液晶面板） 不会由于自身 的重力影响而变形， 保证液晶面板 1的具有较好的平整性， 从而可以较好地 避免液晶面板 1与金属边框 3发生挤压， 进而可以避免液晶面板 1发生暗态 亮度不均不良和漏光不良的现象， 还提升显示器的显示品质。
为使本领域技术人员更好地理解及实现本发明， 以下进一步结合附图 4- 图 12,通过可以实现悬挂液晶面板的液晶显示器来对本发明实施例进行详细 说明。
图 4为本发明实施例提供的液晶显示器的示意图。 参照图 4, 该液晶显 示器包括液晶面板 1、 背光源 2以及金属边框 3, 其中， 液晶面板 1由阵列基 板和彩膜基板对盒并填充液晶而形成， 背光源 2包括光源、 导光板 21、 光学 膜片 20、 胶框 22以及背板 23, 胶框 22将光源、 导光板 21以及光学膜固定 在背板 23上，液晶面板 1扣在背光源 2上，金属边框 3将液晶面板 1压紧在 背光源 2上。 当液晶显示器处于竖直摆放状态时， 液晶面板 1悬挂在背光源 2上。 这里为了便于说明和理解， 以下实施例中以液晶显示器处于竖直摆放 的状态下进行相应的方位描述。
如图 4所示， 上述液晶面板 1悬挂在背光源 2的第一种具体实现方式： 可以是通过胶框 22来承担液晶面板 1的重力，也就是图 4中所示的在液晶面 板 1与胶框 22接触的侧面上设有至少一个挂柱 4, 对应地， 胶框 22中与液 晶面板 1接触的侧面上设有容纳挂柱 4的挂槽 220,不但可以实现液晶面板 1 的悬挂， 还可以在把液晶面板 1水平放置在胶框 22上时， 该挂柱 4和挂槽 220的结构可以便于对液晶面板 1进行更为准确地定位， 方便液晶面板 1的 装配。
承受液晶面板 1的重力还可以是背板 23, 而且在允许的情况的下， 也可 以由金属边框 3来承担液晶面板 1的重力。本发明以胶框 22承担液晶面板 1 的重力为较佳实施例进行详细说明。
由于胶框 22承受液晶面板 1的重力，挂槽 220中位于竖直方向底部的面 为受力面， 尤其对于尺寸较大的液晶面板 1 , 其重量由于较重而使该受力面 损坏， 进而影响液晶面板 1悬挂的稳定性， 为了避免这一现象， 可以在挂柱 4与挂槽 220位于竖直方向底部的接触面之间设有垫片 5。该垫片 5的材质可 以是塑胶材质或硅胶材质等。
可以理解的是， 尽管图中未示出， 但是本领域技术人员还可以清楚地知 道液晶面板 1中两个相对的最外面均为偏光片， 因此液晶面板与胶框接触的 一侧为偏光片。
在将液晶面板 1悬挂在胶框 22上之前，挂柱 4可以采用粘接的方式固定 在液晶面板 1中与胶框 22接触的侧面上（即挂柱 4粘接在偏光片上 ), 或者 也可以与偏光片一体成型， 当然也不局限于此， 还可以是其它本领域技术人 员所示的固定方式， 具体可根据实际情况而择一优选方案进行实施。
挂柱 4的布置可以是如图 5所示的第一种方式， 即在液晶面板 1中与胶 框 22接触的一侧（偏光片）的顶部沿水平方向并排设有多个上述挂柱 4, 对 应地， 胶框 22的顶部沿水平方向并排设有多个挂槽 220, 或者是一个可同时 容纳所述多个挂柱 4的挂槽 220, 这样还可以增加胶框 22中承受液晶面板 1 的受力面积， 以提高液晶面板 1的悬挂稳定性。
挂柱 4的布置的第二种方式为，在液晶面板 1中与胶框 22接触的侧面的 至少一侧沿竖直方向并排设有多个挂柱 4, 对应地， 胶框 22的至少一侧沿竖 直方向并排设有多个挂槽 220, 为了保证结构的强度， 如图 6所示， 可以使 液晶面板 1上的偏光片两侧沿竖直方向均并排设有多个挂柱 4, 且这两排挂 柱 4对称布置。
如图 7所示， 挂柱 4的布置的第三种方式为， 液晶面板 1 中与胶框 22 接触的一侧 （偏光片） 的顶部沿水平方向并排设有多个上述挂柱 4, 以及偏 光片的至少一侧沿竖直方向并排设有多个挂柱 4, 对应地， 胶框 22的顶部沿 水平方向并排设有多个挂槽 220或者是一个可同时容纳所述多个挂柱 4的挂 槽（图中未示 ) , 以及胶框 22的至少一侧沿竖直方向并排设有多个挂槽 220。
需要说明的是， 多个并排的挂柱 4布置形式不局限于上述的三种方式， 并且多个并排的挂柱 4也不局限于均勾布置或不均勾布置， 具体形式视情况 而设定。
如图 8和图 9所示， 上述液晶面板 1悬挂在背光源 2的第二种具体实现 方式为： 液晶面板 1中与胶框 22接触的侧面上设有至少一个凸台 6, 每个凸 台 6上设有凹槽 60; 胶框 22中与液晶面板 1的接触的面上设有容纳在凹槽 60内的凸柱 221。 不但可以实现液晶面板 1的悬挂， 还可以在把液晶面板 1 水平放置在胶框 22上时，还可以便于对液晶面板 1进行更为准确地定位，方 便液晶面板 1的装配。
由于胶框 22承受液晶面板 1的重力，凸台 6中位于竖直方向顶部的面为 受力面， 尤其对于尺寸较大的液晶面板 1 , 其重量由于较重而使该受力面损 坏， 进而影响液晶面板 1悬挂的稳定性， 为了避免这一现象， 凸柱 221与凹 槽 60位于竖直方向顶部的接触面之间设有垫片 5。该垫片 5的材质可以是塑 胶材质或硅胶材质等。 在将液晶面板 1悬挂在胶框 22上之前，凸台 6可以采用粘接的方式固定 在液晶面板 1中与胶框 22接触的侧面上（即凸台 6粘接在偏光片上）， 或者 也可以与偏光片一体成型， 当然也不局限于此， 还可以是其它本领域技术人 员所示的固定方式， 具体可根据实际情况而择一优选方案进行实施。
如图 10所示， 凸台 6布置的第一种方式为， 液晶面板 1中与胶框 22接 触的侧面的顶部沿水平方向并排设有多个具有凹槽 60的凸台 6, 对应地， 胶 框 22的顶部沿水平方向并排设有多个凹槽 60凸柱 221 , 这样还可以增加胶 框 22中 7 受液晶面板 1的受力面积， 以提高液晶面板 1的悬挂稳定性。
凸台 6布置的第二种方式为，在液晶面板 1中与胶框 22接触的侧面的至 少一侧沿竖直方向并排设有多个具有凹槽 60的凸台 6, 对应地， 胶框 22的 至少一侧沿竖直方向并排设有多个凸柱 221 , 为了保证结构的强度， 如图 11 所示，可以使液晶面板 1上的偏光片两侧沿竖直方向均并排设有多个凸台 6, 且这两排凸台 6对称布置。
如图 12所示， 凸台 6布置的第三种方式为， 液晶面板 1中与胶框 22接 触的一侧（偏光片）的顶部沿水平方向并排设有多个上述具有凹槽 60的凸台 6, 以及偏光片的至少一侧沿竖直方向并排设有多个具有凹槽 60的凸台 6, 对应地， 胶框 22的顶部沿水平方向并排设有多个凸柱 221 , 以及胶框 22的 至少一侧沿竖直方向并排设有多个凸柱 221。
需要说明的是，多个并排的凸台 6布置形式也不局限于上述的三种方式， 并且多个并排的凸台 6也不局限于均匀布置或不均匀布置， 具体形式视情况 而设定。
上述液晶面板 1悬挂在背光源 2的第三种实现方式为： 偏光片的顶部沿 水平方向并排设有多个上述具有凹槽 60的凸台 6, 以及偏光片的至少一侧沿 竖直方向并排设有多个上述挂柱 4, 对应地， 胶框 22的顶部沿水平方向并排 设有多个凸柱 221 , 以及胶框 22 的至少一侧沿竖直方向并排设有多个挂槽 220。
上述液晶面板 1悬挂在背光源 2的第四种实现方式为： 偏光片的顶部沿 水平方向并排设有多个上述挂柱 4, 以及偏光片的至少一侧沿竖直方向并排 设有多个上述具有凹槽 60的凸台 6, 对应地， 胶框 22的顶部沿水平方向并 排设有多个挂槽 220或可以同时容纳多个挂柱 4的一个挂槽， 以及胶框 22 的至少一侧沿竖直方向并排设有多个凸柱 221。
此外，偏光片的顶部沿水平方向并排设有多个挂柱 4和多个具有 槽 60 的凸台 6, 且挂柱 4和凸台 6不限于交替布置， 对应地， 胶框 22的顶部沿水 平方向并排设有多个挂槽 220和多个凸柱 221 , 同理也适用于偏光片两侧布 置的悬挂结构。
尽管图中未示出， 但是本领域技术人员人可以知道液晶显示器还可以包 热板、 电路板、 驱动器、 线束等。 并且可以理解的是， 图中所示的液晶 显示器结构也并不构成对液晶显示器结构的限定。
上述液晶显示器可以应用于家用电视、 移动电视、 平板电脑、 PDA ( Personal Digital Assistant, 个人数字助理）、 车载电脑、 手机等具有显示功 能的电子或电器产品。
以上所述仅是本发明的示范性实施方式， 而非用于限制本发明的保护范 围， 本发明的保护范围由所附的权利要求确定。
