Description

用于液晶面板的偏光片及液晶面板 技术领域
本发明属于液晶显示技术领域，具体地讲，涉及一种用于液晶面板的偏光片及液晶面板。
背景技术
随着信息社会的发展，人们对平板显示器的需求得到了快速的增长。液晶显示器(Liquid Crystal Display，简称LCD)具有体积小、功耗低、无辐射等特点，在当前的平板显示器市场占据了主导地位。LCD主要包括用于显示图像的液晶面板以及向液晶面板提供显示光源的背光模块。
图1是现有技术的一种液晶显示器的结构示意图。参照图1，液晶面板1与背光模块2相对设置。液晶面板1从上到下依次包括上偏光片11、上基板12、下基板13和下偏光片14。在背光模块2向液晶面板1提供显示光源时，势必会通过下偏光片14，而经过实验验证，下偏光片14会将背光模块2提供的50％以上的光量吸收掉，使得背光模块2提供的背光的利用率极低，从而导致能耗提高。
发明内容
为了解决上述现有技术存在的问题，本发明的目的在于提供一种用于液晶面板的偏光片，所述偏光片包括基片及间隔形成在所述基片上的反射膜层，其中，所述反射膜层与液晶面板中的黑色矩阵对应。
本发明的另一目的还在于提供一种液晶面板，包括第一基板、第二基板、第一偏光片和第二偏光片，所述第一基板和所述第二基板对盒设置，所述第一基板的下表面上包括黑色矩阵，所述第一偏光片贴附于所述第一基板的上表面上，所述第二偏光片贴附于所述第二基板的下表面上，所述第二偏光片包括基片及间隔形成在所述基片的下表面上的反射膜层，其中，所述反射膜层与所述黑色矩阵对应。
进一步地，所述反射膜层为金属反射膜层。
进一步地，所述反射膜层上形成有间隔布置的凸起。
进一步地，所述凸起的截面形状为三角形或梯形或半圆形。
进一步地，所述第二基板的上表面上包括间隔排布的栅极线，所述栅极线与所述黑色矩阵对应，所述反射膜层与所述栅极线对应。
本发明的有益效果：本发明的液晶面板的偏光片的下表面包括反射膜层，该反射膜层能够将背光模块提供的背光的一部分反射回背光模块中，而反射回背光模块中的部分背光通过背光模块中的反射元件再次提供给液晶面板，从而降低偏光片的光吸收量，提高背光模块的背光利用率，进而降低能耗。

具体实施方式
以下，将参照附图来详细描述本发明的实施例。然而，可以以许多不同的形式来实施本发明，并且本发明不应该被解释为限制于这里阐述的具体实施例。相反，提供这些实施例是为了解释本发明的原理及其实际应用，从而使本领域的其他技术人员能够理解本发明的各种实施例和适合于特定预期应用的各种修 改。在附图中，为了清楚器件，夸大了层和区域的厚度，相同的标号在整个说明书和附图中可用来表示相同的元件。
图2是根据本发明的实施例的液晶显示器的侧视示意图。
参照图2，根据本发明的实施例的液晶显示器包括液晶面板200及与液晶面板200相对设置的背光模块100，其中，背光模块100提供显示光源给液晶面板200，以使液晶面板200显示影像。由于本发明的发明要点是针对液晶面板200，所以为了避免赘述，在本实施例中，背光模块100的具体结构在此不再详细介绍，本领域的技术人员可参照现有技术中公开的背光模块的具体结构。
以下将对根据本发明的实施例的液晶面板200进行详细描述。继续参照图2，根据本发明的实施例的液晶面板200包括：第一基板210、第二基板220、第一偏光片230以及第二偏光片240。第一偏光片230采用现有技术公开的偏光片，其贴附于第一基板210的上表面上。
具体而言，请参照图3，其是根据本发明的实施例的第一基板210的俯视示意图。如图3所示，第一基板210通常称为彩色滤光片(CF)基板，其通常包括第一透明基板211、在第一透明基板211的下表面(或上表面)上的黑色矩阵(BM)212以及在第一透明基板211的下表面(或上表面)上的且由黑色矩阵212围绕的多个彩色光阻(即RGB光阻)213。应当理解的是，第一透明基板211上还可具有例如绝缘层、配向膜层等其他合适类型的元件，由于绝缘层、配向膜层等均为现有技术，为了避免赘述，在此不再详述。
图4是根据本发明的实施例的第二基板220的俯视示意图。参照图4，第二基板220通常称为阵列(Array)基板，其通常包括第二透明基板221以及在第二透明基板221的上表面上的多条栅极线222、多条数据线223、多个开关管(例如薄膜晶体管)224。应当理解的是，第二透明基板221的上表面上还具有例如绝缘层、导电膜层、配向膜层等其他合适类型的元件，由于绝缘层、配向膜层等均为现有技术，为了避免赘述，在此不再详述。通常，栅极线222与数据线223交叉设置，以定义出多个像素区域SP，通常在定义出的像素区域SP中填充液晶。开关管224设置在栅极线222与数据线223的交叉位置处，开光管224通过导电膜层(未示出)控制像素区域SP中的液晶分子的偏转。
参照图3和图4，在第一基板210和第二基板220对盒设置之后，每个彩色光阻213与一个像素区域SP对应，而黑色矩阵212则将所有的栅极线222、所 有的数据线223和所有的开关管224进行遮蔽。也就是说，黑色矩阵212的位置与所有的栅极线222、所有的数据线223和所有的开关管224的位置均对应。
参照图2，第二偏光片240贴附于第二基板220的下表面上。诚如背景技术中所描述的那样，在背光模块100向液晶面板200提供显示光源时，势必会通过第二偏光片240，为了减少第二偏光片240对背光模块100提供的背光的吸收量，本实施例的第二偏光片240具有能够将部分背光反射回背光模块100中的反射膜层242，这部分背光通过背光模块100中反射元件的反射再次提供给液晶面板200，从而提高背光模块100的背光利用率。以下将对根据本发明的实施例的第二偏光片240进行详细描述。
图5是根据本发明的实施例的第二偏光片240的俯视示意图。
参照图2和图5，根据本发明的实施例的第二偏光片240包括基片241及间隔形成在基片241的表面上的反射膜层242。在本实施例中，反射膜层242形成在基片241的下表面上。作为本发明的其他实施方式，反射膜层242也可形成在基片241的上表面上。
基片241的上表面贴附于第二基板220(或者第二透明基板221)的下表面上。
在本实施例中，可通过采用例如图案化的方式在基片241的下表面上形成反射膜层242。进一步地，可通过采用例如图案化的方式在基片241的下表面上形成多个彼此独立的反射膜层242。
进一步地，为了提高反射膜层242的反射面积，在本实施例中，可在反射膜层242上形成凸起243。该凸起243的截面形状可例如是三角形(图6所示)、半圆形(图7所示)或梯形(图8所示)，但本发明并不限制于此。
参照图4和图5，每个反射膜层242与第二基板220的一条栅极线222对应。
进一步地，作为本发明的其他实施方式，参照图9，其是根据本发明的另一实施例的第二偏光片240的俯视示意图，也可通过采用例如图案化的方式在基片241的下表面上形成能够围绕形成多个窗口244的反射膜层242’。进一步参照图4和图9，经图案化后形成的反射膜层242’与第一基板210的黑色矩阵212对应，并且每个窗口244与第一基板210的一个彩色光阻213对应。
进一步地，为了提高反射膜层242’的反射面积，在本实施例中，也可在反 射膜层242’上形成如图6至图8所示的凸起243。
此外，优选地，反射膜层242和242’可为具有高反射率的金属反射膜层，例如具有高反射率的铝膜层、银膜层等。
虽然已经参照特定实施例示出并描述了本发明，但是本领域的技术人员将理解：在不脱离由权利要求及其等同物限定的本发明的精神和范围的情况下，可在此进行形式和细节上的各种变化。
