其中， 为了提高第二支架 7的弹性， 在第四延伸板 72和第五延伸板 73 端部的另一侧均形成有第二凹槽 75， 且在第四延伸板 72和第五延伸板 73 上均匀设置有缺口 76， 每一缺口 76位于两个第二视窗口 70之间。
其中， 第一支架 6上的多个第一视窗口 60与第二支架 7上的多个第二 视窗口 70——正对， 且每一第二视窗口与侧入式背光源 3的一个 LED灯正 对， 另外每一第一视窗口 60的面积大于每一第二视窗口 70的面积， 可以使 尽可能多的光源射入到导光板 2中。
另外，在背板 1与导光板 2之间进一步设置有一散热板 11， 第三延伸板 65放置于散热板 11之上。
另外， 该液晶模组进一步包括：

本发明的组装是顺序为，先将易碎的包含有量子条 5的玻璃管放置在第 二支架 5形成的凹槽内， 然后扣合第一支架 6。 其中第一支架 6的凸条 64 上的卡勾与第二支架 7上的第一凹槽 74相配合， 可以快速将两者扣合起来， 从而使量子条 5固定在由第一支架 6和第二支架 7形成的容纳空间内。
相应地， 本发明实施例还提供一种液晶显示装置， 其釆用前述图 1至图 6所描述的液晶模组， 具体的细节可以详见前述的描述， 在此不进行赘述。
实施本发明的实施例， 具有如下的有益效果：
在本发明实施例中，将量子条放置于由第一支架和第二支架组成的容纳 空间内， 且第一支架与第二支架组装方式非常方便， 故使量子条的安装固定 非常简便；
另外， 由于在第二支架上设置了第二凹槽以及缺口， 提高了其弹性， 降 低了量子条在容纳空间中的安全性， 减少了最子条玻璃管的破碎风险， 提高 了产品良率。 以上所揭露的仅为本发明较佳实施例而已， 当然不能以此来限定本发明 之权利范围， 因此等同变化， 仍属本发明所涵盖的范围。
