图 2是本发明背光模组实施例一的局部结构示意图；
图 3是图 2中导光板的结构示意图；
图 4是本发明背光模组实施例二的局部结构示意图。
其中： 1、 背光模组； 11、 导光板； 111、 凸耳； 112、 根部； 113、 切口； 12、 中框； 121、 凹槽； 13、 光学膜片； 2、 液晶显示面板； 3、 光源。
【具体实施方式】
本发明公开一种液晶显示装置， 包括背光模组， 作为本发明背光模组的实 施例一， 如图 2和图 3所示， 所述背光模组为底面入光式的背光模组， 背光模 组包括中框 12、 导光板 11和光源 3 , 所述背光模组还包括防止光源 3的光线从 中框 12和导光板 11之间的间隙直接射出的遮挡结构， 所述遮挡结构包括设置 在中框 12上的凹槽 121和设置在导光板 11上的凸耳 111 , 所述凸耳 111设置在 凹槽 121内。 本实施例中， 所述凸耳 111截面形状为矩形， 所述凸耳 111和凹槽 121形状相对应， 从而使凸耳 111和凹槽 121配合结构具有定位作用。 为了能够 完全遮挡光线， 所述凸耳的长度最好大于或等于光源的长度。
本发明所述背光模组由于设置了防止光源的光线从中框 12和导光板 11之 间的间隙直接射出的遮挡结构， 即设置在中框 12上的凹槽 121和设置在导光板 11上的凸耳 111 , 凸耳 111和凹槽 121的配合结构可以遮挡光线，使光线无法从 中框 12和导光板 11之间的间隙直接射到光学膜片上， 解决了漏光问题， 液晶 显示面板自然也就不会出现亮线和光斑， 从而提高了液晶显示装置的品质。 另 外， 导光板 11上的凸耳 111可以作为中框 12固定导光板 11的着力点， 即在上 下两个方向对导光板 11进行夹持固定， 可以牢固地定位导光板 11 , 避免导光板 11 曲变形。
另外因为中框 12夹持导光板 11的地方处于导光板 11的入光面以外， 而不 是延伸到入光面内， 从而可以进一步缩短液晶显示装置边框宽度 2mm左右， 从 而实现超窄边框的设计目的。
由于导光板 11主要通过裁切加工而成， 在导光板 11 的边缘设置凸耳 111 会使板材的利用率降低， 造成材料的浪费。 本发明为了解决这个问题， 凸耳 111 可采用和导光板 11相同的材质分体制作， 为独立部件， 如图 3所示， 导光板 11 为矩形， 导光板 11的边缘处设有 T形切口 113 , 所述凸耳 111包括根部 112, 所述凸耳根部 112设置在切口 113内， 并把凸耳 111和导光板 11固定为一体。 即先把凸耳 111与导光板 11分别制作出来，再把凸耳 111与导光板 11通过装配 成一体， 由于导光板 11直接设计成矩形， 在裁切时板材的利用率非常高， 而凸 耳 111由于宽度较小，可以利用板材的边角料进行加工。 当然所述凸耳 111也可 以直接粘贴在导光板 11上。 作为本发明背光模组的实施例二， 如图 4所示， 与实施例一不同之处在于 所述导光板 11上的凸耳 111截面形状为三角形，中框 12上凹槽 121的截面形状 为与凸耳 111相适配的三角形。 此种配合方式可以使中框 12对导光板 11 凸耳 111的下端面部分夹持更加强劲有力，从而更好地固定导光板 11 , 更好地避免导 光板 11翘曲变形， 其他结构及有益效果均实施例——致， 此处不再赘述。
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。
