技术领域
本发明涉及液晶显示器生产技术领域，尤其是涉及一种用于曲面液晶显示器的背光模组和曲面液晶显示器。
背景技术
近来，QD(量子点)作为液晶显示器高色域背光技术之一，其得到了越来越多的关注。而具有QD的液晶显示器的主要结构为在蓝光LED光源的前面设置一根量子管，当蓝光进入量子管后激发其内部所封装的量子点QD产生红光和绿光，从而加上原有的部分蓝光混合成具备高色饱的白光进入到导光板中，从而为液晶显示器提供更高色彩饱和度的光线，提高了显示器对色彩的表现能力。量子管能够使得液晶面板的色彩纯度得到提高，同时不需要加强彩色滤光片的色彩浓度，因此液晶面板的功耗也不会增加。另外，液晶面板的色域也会随之扩大，例如可增大30％左右。
图1显示了现有技术中常见的量子管的纵向剖视图；图2显示了现有技术中常见的量子管的沿横截面的剖视图。参照图2，量子管10通常包括位于内部的发挥作用的功能部分13和包裹着功能部分13的封装部分14，功能部分13通常由构成量子点的材料制成，封装部分14通常由玻璃材料制成。并且，参照图1，可以看出量子管10在其纵向上分为位于中部的发挥作用的有效区11和位于两侧的无效区12。
当液晶显示器为曲面时，由于量子管本身为刚性很难应用到其中。现有技术中，常常将量子点设置在光源或者其它光线材料上以提高液晶显示器的色彩纯度。而这种生产液晶显示器的方式操作复杂，生产成本较高，同时整个显示器的显示效果并不理想。
发明内容
针对现有技术中所存在的上述技术问题，本发明提出了一种用于曲面液晶显示器的背光模组和包括背光模组的曲面液晶显示器。该背光模组能将量子管应用于曲面液晶显示器中，从而能提高曲面液晶显示器的表现能力和色域。同时，具有这种结构的背光模组生产工艺简单，生产成本低。
根据本发明的一方面，提出了一种用于曲面液晶显示器的背光模组，包括背板以及设置在背板内的导光板和背光源，在导光板和背光源之间设有量子管，其中量子管之间形成匹配于曲面液晶显示器的曲面的折线。
由于量子管之间形成折线，这折线能拟合为曲线以适应曲面液晶显示器的曲面。从而，通过这种设置方式能将量子管应用于曲面液晶显示器，以提高曲面液晶显示器的色彩纯度，并扩大其色域。同时，该背光模组能简化生产操作，并降低生产成本。
在一个实施例中，相邻的两个量子管之间具有部分重叠。优选地，相邻的两个量子管中的一个量子管的有效区延伸到另一个量子管的有效区。通过这种设置，使得背光源均能对应到量子管的有效区内，从而有助于导光板的入光设计能避开量子管的无效区。
在一个实施例中，导光板的入光侧设置有槽，槽构造为匹配由量子管形成的折线的阶梯槽。通过这种设置使导光板限定了量子管的位置，并使形成为折线的量子管安装方便，操作简单。
在一个实施例中，槽包括一个或两个中间槽和设置在中间槽的两侧的侧槽，在由中间槽到侧槽的方向上槽的槽底面依次降低。通过这种设置使得槽形状拟合的曲线更容易贴合曲面液晶显示器的曲面。同时，这种结构的槽加工简单。另外，这种设置方便了量子管的定位。
在一个实施例中，侧槽关于中间槽对称。通过这种设置，简化了槽的整体结构，降低了导光板的加工难度。
在一个实施例中，侧槽的槽底设置为在由中间向两侧方向上逐渐降低的斜面。通过这种设置使得槽形状更贴近于曲面液晶显示器的曲面。
在一个实施例中，匹配于中间槽的同一侧的侧槽的量子管沿同一方向依次设置。通过这种设置简化了量子管的安装，减低了生产成本。
在一个实施例中，量子管的长度为1-20cm。这种设置的量子管有助于量子管以直代曲而拟合到曲面液晶显示器的曲面。
根据本发明的第二方面，提供一种曲面液晶显示器，包括上述的背光模组。
与现有技术相比，本发明的优点在于，通过量子管之间形成折线以匹配曲面液晶显示器的曲面，从而避免了在曲面液晶显示器中只能应用量子点设置在光源或光线材料上的问题。进一步地，该背光模组具有结构简单，生产成本低的优点。
附图说明
下面将结合附图来对本发明的优选实施例进行详细地描述，在图中：
图1显示了现有技术中常见的量子管的纵向剖视图；
图2显示了现有技术中常见的量子管的沿横截面的剖视图；
图3显示了根据本发明的实施例的曲面液晶显示器的截面图；
图4显示了根据本发明的实施例的导光板和量子管的结构图；
图5显示了来自图4的A处的放大图；
图6显示了根据本发明的实施例的量子管的形成折线的结构图；
在附图中，相同的部件使用相同的附图标记，附图并未按照实际的比例绘制。
具体实施方式
下面将结合附图对本发明做进一步说明。
图3显示了根据本发明的曲面液晶显示器200。如图3所示，曲面液晶显示器200包括背光模组100。背光模组100包括背板1以及设置在背板1内的导光板2和背光源3，在导光板2和背光源3之间设有量子管4，由图5中可以看出。由于，曲面液晶显示器200为曲面状，所以量子管4采用拼接形成折线，以匹配曲面液晶显示器200的曲面，如图6所示。需要说明的是，用语“拼接”并不限于量子管4之间接触性连接，还包括量子管4之间不接触但能组合为一定形状。
由于量子管4本身由刚性材料制成，则单一的量子管4本身并不能随着曲面液晶显示器200的曲面而弯曲。通过上述多个量子管4拼接形成折线，并使折线能拟合为曲线以适应曲面液晶显示器200的曲面。从而，通过上述方式能将量子管4应用于曲面液晶显示器200，以提高曲面液晶显示器200的色彩纯度和色域。同时，具有这种结构的曲面液晶显示器200结构简单，生产成本低。
根据本发明，相邻的两个量子管4之间部分重叠。优选地，相邻的两个量子管4中的一个量子管4的有效区5延伸到另一个量子管4的有效区5。通过这种设置，则一个量子管4的无效区6始终能与另一个量子管4的有效区5重叠，使得背光源3均能对应到量子管4的有效区5内，从而有助于导光板2的入光设计能避开量子管4的无效区6。
需要说明地是，相邻的两个量子管4中的一个量子管4的有效区5并不一定要延伸到另一个量子管4的有效区5内，例如，如图5所示的。在这种情况下，需要优化背光源3和量子管4的相对位置，也就是需要保证背光源3要处于量子管4的有效区5内。
如图4所示，导光板2的入光侧设置有槽7。槽7构造为阶梯槽，以限定量子管4并匹配 于量子管4所形成的折线。槽7的数量与量子管4的数量对应。通过这种设置使导光板2限定了量子管4的位置，使得量子管4的安装方便，操作简单。同时，导光板2采用这种阶梯式入光设计能保证量子管4重叠，以有助于导光板2的入光能避开量子管4的无效区6。
如图4所示，槽7包括一个中间槽8和设置在中间槽8的两侧的侧槽9。由中间槽8到侧槽9方向上，槽7的槽底面依次降低。也就是，槽7构造为在由中间向两侧方向上逐渐降低的台阶状。通过这种设置使得通过槽7拟合的曲线更容易贴合曲面液晶显示器200的曲面。另外，这种结构的槽7加工简单，同时，方便了量子管4的定位。
需要说明的是，槽7还可以包括两个中间槽8和设置在中间槽8的两侧的侧槽9。同时，在由中间槽8到侧槽9方向上，槽7的槽底面依次降低。与两个中间槽8相对应的量子管4可以为相对式设置。在这种情况下，处于中间槽8的量子管4的无效区6并不一定能与其它电子管4的有效区5重叠。由此，就要考虑背光源3的设置位置，即使背光源3不能处于量子管4的无效区6处。
为了降低导光板2的加工难度，简化槽7的结构，侧槽9关于中间槽8对称。优选地，在由中间向两侧方向上，侧槽9的槽底设置为逐渐降低的斜面。也就是说，侧槽9的槽底面为倾斜面，并且此倾斜面靠近中间槽8的一侧高，而另一侧低。通过这种设置使得槽7的整体形状更贴近于曲面液晶显示器200的曲面。
需要说明的是，在具有两个中间槽8的情况下，中间槽8的槽底也可以设置为由中间向两侧逐渐降低的斜面。
根据本发明，由图4所示，匹配于中间槽8的同一侧的侧槽9的量子管4沿同一方向依次设置。也就是，在图4中，位于中间槽8的左边的量子管4依次设置，并且量子管4沿同一方向设。例如，中间槽8的同一侧的量子管4的尖头状的无效区6向同一侧突出。优选地，量子管4的设置也关于中间槽8对称，例如，同一侧的量子管4的尖头状的无效区6向外侧延伸。这种设置简化了量子管4的安装，减低了生产成本。同时，这种结构能进一步地使导光板2的入光避免量子管4的无效区6。
为了保证曲面液晶显示器200的显示效果，量子管4所形成的折线应能更密切地匹配曲面液晶显示器200的曲面。从而，量子管4的长度为1-20cm。在这种情况下，根据曲面液晶显示器200的尺寸，设置多个不同长度或相同长度的量子管4以使得量子管4能以直代曲而拟合到曲面液晶显示器200的曲面。
曲面液晶显示器200还包括其它结构和部件，而这些结构和部件是本领域技术人员熟知的，在此不再进行赘述。
以上所述仅为本发明的优选实施方式，但本发明保护范围并不局限于此，任何本领域的技 术人员在本发明公开的技术范围内，可容易地进行改变或变化，而这种改变或变化都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以权利要求书的保护范围为准。
