本申请要求享有于2015年5月27日提交的名称为“液晶显示面板和液晶显示器”的中国专利申请CN201510278387.1的优先权，该申请的全部内容通过引用并入本文中。
技术领域
本发明涉及液晶显示技术领域，具体涉及液晶显示面板和液晶显示器。
背景技术
目前现有的液晶显示面板中，通常以白光发光二极管(LED)为光源，其频谱中主要包含了蓝光成分，绿光成分和红光成分。当白光入射到显示面板上时，一部分会被黑矩阵吸收，另一部分会被彩色滤光片吸收。其中，红色滤光片可透过频谱中的红光部分，而很难透过其它颜色的光，并且大部分其它颜色的光会被红色滤光片吸收；同样地，绿色滤光片和蓝色滤光片可分别透过频谱中的绿光部分和蓝光部分，而其它颜色的光大部分被所对应的滤光片所吸收。由于彩色滤光片的这种特性，使得彩色滤光片对发光二极管发出的光的穿透率不到30％。这便导致了背光模组中大量的光损失，为提高背光模组的亮度，就需要使用较多的发光二极管(LED)或较好的彩色滤光片材料，致使成本提高。
针对上述技术存在的问题，在本领域中希望寻求一种可进一步提高背光模组中光源的光利用率的液晶显示面板，从而进一步提高背光模组的亮度，以解决现有技术中的不足之处。
发明内容
本发明针对现有技术的不足之处，提出了一种液晶显示面板和应用该液晶显示面板的液晶显示器。
根据本发明提供的一种液晶显示面板，包括相对设置的上玻璃基板和下玻璃基板。其中，上玻璃基板包括设置在上玻璃基板上的多个色阻单元，色阻单元包 括相互间隔开的红色色阻、绿色色阻和蓝色色阻，上玻璃基板还包括设置在相邻两个颜色色阻之间的黑色矩阵；下玻璃基板包括设置在其外表面上的分别与红色色阻、绿色色阻和蓝色色阻相对应并具有相应颜色的滤光膜层。
本发明通过在与红色色阻、绿色色阻和蓝色色阻相对应的下玻璃基板的表面设置相应颜色的滤光膜层，使背光源发出的光经过滤光膜层选择性透过与对应的颜色的色阻相同的颜色，而反射其他颜色的光，反射出的其他颜色的光继续被背光源利用，与现有技术中未设置滤光膜层的液晶显示面板相比，本发明避免了因背光源发出的光中与对应色阻的颜色不一致的光被该色阻吸收而导致的光损失，因此大大地提高了背光源的光利用率，进而提高了液晶显示器的亮度。此外，本发明只需在相应的位置贴附滤光膜层即可达到液晶显示器良好的显示效果，其生产简单方便。
在一些实施方案中，不同颜色的滤光膜层分别设置在远离上玻璃基板的下玻璃基板的外表面上。通过这种设置可简化生产工艺流程，直接将滤光膜层贴附在下玻璃基板的外表面即可，避免将滤光膜层贴附在下玻璃基板的内表面时给生产带来不便。
在一些实施方案中，不同颜色的滤光膜层的通光面积与对应的色阻的通光面积相等。这样设置可充分保证经过滤光膜层透射的光完全通过相应颜色的色阻，同时将相应滤光膜层不能透过的光反射回背光源，以此最大限度地利用背光源所发出的光。
在一些实施方案中，不同颜色的滤光膜层中的任意一个由多个具有不同折射率的膜层叠置制成。通过控制膜层的层数、每层的厚度及层叠方式来使滤光膜层具有不同的透光性能，即对不同波段的光具有选择透过性，以便与与其相对应的不同颜色的色阻形成配合，达到更好的出光效果。
在一些实施方案中，膜层由二氧化硅、二氧化钛或氟化镁中的一种制成。
在一些实施方案中，黑色矩阵的外表面至少部分覆盖有反射层。这种设置可避免背光源发出的光直接入射到黑色矩阵上而被黑色矩阵吸收，通过反射层的反射，光线被反射回背光源继续被背光源利用，从而提高了背光源的光利用率。
在一些实施方案中，反射层完全覆盖黑色矩阵。反射层完全覆盖黑色矩阵可完全避免进入的光线因被黑色矩阵吸收而造成的光损失，经反射层反射回背光源的光被充分利用，从而进一步提高了背光源的光利用率。
在一些实施方案中，反射层设置成与下玻璃基板平行。当反射层相对于下玻璃基板倾斜设置时，一部分白光直接被反射进入色阻所在的区域而被色阻吸收，另一部分白光经过滤光膜层将对应色阻颜色的光透射出下玻璃基板，而将其他色光反射回对应的色阻中，而由于此时对应的色阻并不能出射这些其他颜色的光，因此这部分光会被色阻吸收而导致光损失。而反射层设置成与下玻璃基板平行，可使入射光线垂直反射回背光源中，因此避免了因反射层倾斜设置时的光损失。
在一些实施方案中，反射层为金属层。该金属层优选为铝或银，其可直接涂覆在黑色矩阵的表面，工艺操作简单方便。
根据本发明提供的一种液晶显示器，包括上述液晶显示面板。
与现有技术相比，本发明具有以下优点：
1)本发明在下玻璃基板上贴附与对应色阻相同颜色的滤光膜层，使滤光膜层透射出与对应色阻相同颜色的光并由上玻璃基板射出，而与对应色阻不同颜色的光被滤光膜层反射回背光源，避免了该部分光被相应色阻吸收，这便提高了背光源的光利用率，进而提高了液晶显示器的亮度；
2)本发明只需在相应的位置贴附滤光膜层即可达到液晶显示器良好的显示效果，其生产工艺简单可靠，生产成本较低；
3)本发明还在黑色矩阵上增设反射层，以减少黑色矩阵对光的吸收，同时，经反射层反射回背光源的光再次被利用，进一步提高了背光源的光利用率。
附图说明
在下文中将基于实施例并参考附图来对本发明进行更详细的描述。其中：
图1是根据本发明的液晶显示面板的结构示意图。
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作进一步说明。
这里所介绍的细节是示例性的，并仅用来对本发明的实施例进行例证性讨论，它们的存在是为了提供被认为是对本发明的原理和概念方面的最有用和最易理解的描述。关于这一点，这里并没有试图对本发明的结构细节作超出于基本理解本发明所需的程度的介绍，本领域的技术人员通过说明书及其附图可以清楚地 理解如何在实践中实施本发明的几种形式。
图1显示了根据本发明提供的一种液晶显示面板100的结构示意图。该液晶显示面板100包括背光源70，相对设置的上玻璃基板30和下玻璃基板50。其中，上玻璃基板30包括多个色阻单元，色阻单元包括相互间隔开的红色色阻31、绿色色阻32和蓝色色阻33，上玻璃基板30还包括设置在相邻两个颜色色阻之间的黑色矩阵34；下玻璃基板50包括设置在其外表面上的分别与红色色阻31、绿色色阻32和蓝色色阻33相对应并具有相应颜色的滤光膜层51(图中仅示例性地标出一个)。值得注意的是，滤光膜层51的颜色与与其对应的色阻的颜色相同，以便其可以透射出与相应色阻相同颜色的光。
本发明通过在与红色色阻31、绿色色阻32和蓝色色阻33相对应的下玻璃基板50的表面设置相应颜色的滤光膜层51，使背光源70发出的光经过滤光膜层51选择性透过与对应的颜色的色阻相同的颜色，而反射其他颜色的光，反射出的其他颜色的光继续被背光源70利用，与现有技术中未设置滤光膜层的液晶显示面板相比，本发明避免了因背光源70发出的光中与对应色阻的颜色不一致的光被该色阻吸收而导致的光损失，因此大大地提高了背光源70的光利用率，进而提高了液晶显示面板100的亮度。此外，本发明只需在相应的位置贴附滤光膜层51即可达到液晶显示面板良好的显示效果，其生产工艺简单可靠。
如图1所示的实施例中，背光源70发出的白光71经过相应的红色滤光膜层后，白光71中的红光被红色滤光膜层透射形成红光711并最终由对应的红色色阻31出射到上玻璃基板30外，而白光71中的蓝光712和绿光713则被红色滤光膜层反射回背光源70，从而再次被背光源70利用。同样地，其它颜色的色阻和对应颜色的滤光膜层也具有上述相同的工作原理，这里不再赘述。
根据本发明，不同颜色的滤光膜层51分别设置在远离上玻璃基板30的下玻璃基板50的外表面上。通过这种设置可简化工艺流程，直接将滤光膜层51贴附在下玻璃基板50的外表面，避免将滤光膜层贴51附在下玻璃基板50的内表面时给生产带来不便。
优选地，不同颜色的滤光膜层51的通光面积与对应的色阻的通光面积相等。例如红色滤光膜层的通光面积与红色色阻31的通光面积相等，这样设置可充分保证经过红色滤光膜层透射的红光完全通过红色色阻31，同时将红色滤光膜层不能透过的蓝光712和绿光713反射回背光源70，以此最大限度地利用背光源70 发出的光，提高了背光源的光利用率。
根据本发明，不同颜色的滤光膜层51中的任意一个由多个具有不同折射率的膜层叠置制成。通过控制膜层的层数、每层的厚度及层叠方式来使滤光膜层51具有不同的透光性能，即对不同波段的光具有选择透过性，以便与与其相对应的不同颜色的色阻形成配合，达到更好的出光效果。优选地，膜层由二氧化硅、二氧化钛或氟化镁中的一种制成。
根据本发明，如图1所示，黑色矩阵34的外表面至少部分覆盖有反射层341。这种设置可避免背光源70发出的光直接入射到黑色矩阵34上而被黑色矩阵34吸收，通过反射层34的反射，光线被反射回背光源70继续被背光源70利用，从而提高了背光源70的光利用率。
优选地，反射层341完全覆盖黑色矩阵34。反射层341完全覆盖黑色矩阵34可完全避免进入的光线因被黑色矩阵34吸收而造成的光损失，经反射层341反射回背光源70的光被充分利用，从而进一步提高了背光源70的光利用率。
进一步优选地，反射层341设置成与下玻璃基板50平行。例如，由背光源70发出的光线72经过下玻璃基板50到达反射层341，由于下玻璃基板50与反射层341平行，则入射光线72经反射后形成垂直的出射光线73，并最终到达背光源70中；当反射层341相对于下玻璃基板50倾斜设置时，这里以红色色阻31为例进行阐述，当入射光线72到达反射层341时，一部分白光直接被反射进入红色色阻31所在的区域而被红色色阻31吸收，另一部分白光经过对应的红色滤光膜层将红光透射出下玻璃基板50，而将蓝光和绿光反射回红色色阻31中，而由于此时红色色阻31并不能出射这些蓝光和绿光，因此这部分光会被红色色阻31吸收而导致光损失。因此，与反射层341倾斜设置相比，本发明的设置进一步提高了背光源70的光利用率。
优选地，反射层341为金属层。该金属层优选为铝或银，其可直接涂覆在黑色矩阵34的表面，工艺操作简单方便。
根据本发明提供的一种液晶显示器，包括上述液晶显示面板100。该液晶显示器的其他结构可设置成与现有技术相同或相似，其工作原理为本领域技术人员所熟知，这里不再赘述。
应注意的是，前面所述的例子仅以解释为目的，而不能认为是限制了本发明。虽然已经根据示例性实施例对本发明进行了描述，然而应当理解，这里使用的是 描述性和说明性的语言，而不是限制性的语言。在当前所述的和修改的所附权利要求的范围内，在不脱离本发明的范围和精神的范围中，可以对本发明进行改变。尽管这里已经根据特定的方式、材料和实施例对本发明进行了描述，但本发明并不仅限于这里公开的细节；相反，本发明可扩展到例如在所附权利要求的范围内的所有等同功能的结构、方法和应用。
