在目前常见的白色背光中，其发光原理为蓝色发光二极管(Light-EmittingDiode，LED)激发黄色荧光粉，其色域饱和值NTSC约在60％～80％之间，为了提升NTSC值，目前采用蓝光LED激发纳米级的量子点，利用量子效应，可使NTSC达到100％以上，提升面板的显示品质。
目前通常将量子点分装在量子条内，以对量子点进行保护。然而现有的量子条(QD)固定的比较牢固，由于其安装位置的空间比较狭窄，不方便更换，导致容易损坏量子条。
因此，有必要提供一种背光模组及液晶显示装置，以解决现有技术所存在的问题。

以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。在图中，结构相似的单元是以相同标号表示。
请参照图1，图1为本发明的背光模块的结构示意图；
如图1所示，本发明的背光模块，包括散热板11、导光板13、中框14、光源16、量子条17；导光板13设置于所述散热板11和中框14之间；所述导光板具有入光侧121和发光侧，当然在所述散热板11下方还可设置背板；
所述光源16设置在所述导光板13的入光侧121；所述背光模组还可包括背框15，所述光源16固定在所述背框15的侧壁的内表面上，所述光源16比如为蓝色LED光源。所述中框14位于所述导光板13和所述光源16上；也即盖在所述导光板13和所述光源16上；在所述散热板11上设置有凹槽111，在所述凹槽111内设置有第一缓冲块18；所述量子条17插入所述凹槽111内，且所述量子条17的一端部与所述第一缓冲块18相抵接，所述第一缓冲块18可以粘结在所述凹槽111的底部。
如图2所示，本发明的量子条17包括第一基板31以及第二基板32，所述量子点材料34填充在第一基板31和第二基板32之间，第一基板31和第二基板32四周的边缘通过框胶33粘结在一起。
由于在插入量子条的凹槽底部设置缓冲块，从而可以在更换量子条的时候，更加方便，避免与凹槽底部碰撞，防止损坏量子条。
所述背框15的侧壁的内表面上还可设置有第二缓冲块19，所述第二缓冲块19与所述量子条17之间的间距小于所述光源16与所述量子条17之间的间距，也即第二缓冲块19的厚度(即图中水平方向的宽度)大于所述光源16的厚度。由于第二缓冲块19的厚度大于所述光源16的厚度，从而防止在量子条倾斜时与光源发生碰撞，避免损坏光源。
优选地，所述第二缓冲块19与所述中框14之间的间距小于所述光源16与所述中框14之间的间距，也即所述第二缓冲块19位于所述光源上方，也即所述第二缓冲块更靠近所述中框。由于量子条的顶端未固定，因此，将第二缓冲块设置在量子条顶端位置，可以更好地防止量子条倾斜时与光源发生碰撞。
优选地，所述第二缓冲块19粘结在所述背框15的侧壁的内表面上，从而可以方便地更换第二缓冲块。
为了增强第二缓冲块的固定性，优选地，所述第二缓冲块19的朝向所述中框14的端部粘结在所述中框上，也即所述第二缓冲块19的上端部与所述中框14朝向散热板一侧的表面粘结。
优选地，在所述导光板13的第一侧以及所述中框14的第二侧之间设置有第三缓冲块20，该第一侧为朝向所述中框14的一侧以及所述第二侧为朝向所述散热板11的一侧，所述第三缓冲块20与所述量子条17之间的间距小于所述导光板13与所述量子条17之间的间距，也即所述第三缓冲块20设置在所述导光板13靠近量子条17的上方，且第三缓冲块靠近所述量子条的一侧超出导光板的入光面，从而防止在量子条倾斜时与导光板发生碰撞，避免损坏导光板。
优选地，所述背光模组还可包括反射片12，所述反射片12设置于所述导光板13和所述散热板11之间。所述中框14的材料可以为塑料。
本发明的背光模组，通过在现有散热板上设置凹槽，并在凹槽底部设置缓冲块，将量子条插在具有缓冲块的凹槽中，从而便于更换量子条，防止损坏量子条。
本发明还提供一种液晶显示装置，其包括背光模组和液晶显示面板，如图1所示，本发明的背光模块，包括散热板11、导光板13、中框14、光源16、量子条17；导光板13设置于所述散热板11和中框14之间；所述导光板具有入光侧121和发光侧，当然在所述散热板11下方还可设置背板；
所述光源16设置在所述导光板13的入光侧121；所述背光模组还可包括背框15，所述光源16固定在所述背框15的侧壁的内表面上，所述光源16比如为蓝色LED光源。所述中框14位于所述导光板13和所述光源16上；也即盖在所述导光板13和所述光源16上；在所述散热板11上设置有凹槽111，在所述凹槽111内设置有第一缓冲块18；所述量子条17插入所述凹槽111内，且所述量子条17的一端部与所述第一缓冲块18相抵接，所述第一缓冲块18可以粘结在所述凹槽111的底部。
如图2所示，本发明的量子条17包括第一基板31以及第二基板32，所述量子点材料34填充在第一基板31和第二基板32之间，第一基板31和第二基板32四周的边缘通过框胶33粘结在一起。
由于在插入量子条的凹槽底部设置缓冲块，从而可以在更换量子条的时候，更加方便，避免与凹槽底部碰撞，防止损坏量子条。
所述背框15的侧壁的内表面上还可设置有第二缓冲块19，所述第二缓冲块19与所述量子条17之间的间距小于所述光源16与所述量子条17之间的间距，也即第二缓冲块19的厚度(即图中水平方向的宽度)大于所述光源16的厚度。由于第二缓冲块19的厚度大于所述光源16的厚度，从而防止在量子条倾斜时与光源发生碰撞，避免损坏光源。
优选地，所述第二缓冲块19与所述中框14之间的间距小于所述光源16与所述中框14之间的间距，也即所述第二缓冲块19位于所述光源上方，也即所述第二缓冲块更靠近所述中框。由于量子条的顶端未固定，因此，将第二缓冲块设置在量子条顶端位置，可以更好地防止量子条倾斜时与光源发生碰撞。
优选地，所述第二缓冲块19粘结在所述背框15的侧壁的内表面上，从而可以方便地更换第二缓冲块。
为了增强第二缓冲块的固定性，优选地，所述第二缓冲块19的朝向所述中框14的端部粘结在所述中框上，也即所述第二缓冲块19的上端部与所述中框14朝向散热板一侧的表面粘结。
优选地，在所述导光板13的第一侧以及所述中框14的第二侧之间设置有第三缓冲块20，该第一侧为朝向所述中框14的一侧以及所述第二侧为朝向所述散热板11的一侧，所述第三缓冲块20与所述量子条17之间的间距小于所述导光板13与所述量子条17之间的间距，也即所述第三缓冲块20设置在所述导光板13靠近量子条17的上方，且第三缓冲块靠近所述量子条的一侧超出导光板的入光面，从而防止在量子条倾斜时与导光板发生碰撞，避免损坏导光板。
优选地，所述背光模组还可包括反射片12，所述反射片12设置于所述导光板13和所述散热板11之间。所述中框14的材料可以为塑料。
本发明的液晶显示装置，通过在现有散热板上设置凹槽，并在凹槽底部设置缓冲块，将量子条插在具有缓冲块的凹槽中，从而便于更换量子条，防止损坏量子条。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
