具体实施方式
为使本领域的技术人员更好地理解本发明的技术方案，下面结合附图对本发明提供的半透半反显示面板和半透半反显示装置进行详细描述。
图1为根据本发明实施例的半透半反显示面板的结构示意图。
如图1所示，半透半反显示面板可以划分为形成有反射电极的反射区和没有形成反射电极的透射区。半透半反显示面板可以包括相对设置的第一基板11和第二基板12以及设置在第一基板11和第二基板12之间的蓝相液晶13。第一基板11可以包括第一衬底基板111和设置在第一衬底基板111上的像素电极112和公共电极113。像素电极112和公共电极113设置在第一衬底基板111面对第二基板12的一侧上。第二基板12可以包括第二衬底基板121。根据本实施例，像素电极112和公共电极113可以都用作反射电极。
蓝相液晶13在没有驱动电压的情况下宏观上具有各向同性的优点，并且蓝相液晶13还具有快速响应的优点。
根据本发明的实施例，反射电极可采用不透明金属制成。例如，反射电极可采用高反射率的不透明金属制成。
根据本发明的实施例，第一基板11可以为阵列基板，第二基板12可以为彩膜基板。图2为图1中子像素的示意图。
如图2所示，在半透半反显示面板上形成多个像素，每个像素可以包括交替设置的透射子像素(例如，示出为R、G和B的子像素)和反射子像素(例如，示出为形成有反射电极的子像素)。形成有反射电极的区域为半透半反显示面板的反射区，没有形成反射电极的区域为半透半反显示面板的透射区。透射子像素可以包括红色子像素R、绿色子像素G或者蓝色子像素B。
在图2所示的示例中，每个像素包括依次横向排列的红色子像素R、反射子像素、绿色子像素G、反射子像素、蓝色子像素B、反射子像素。可通过在第二衬底基板121上设置色阻(图中未示出)来形成相应颜色的透射子像素。应当认识到，可以对各个透射子像素的颜色以及透射子像素与反射子像素的排列方式进行各种改变，本申请不对此进行限定。
根据本发明的实施例的半透半反显示面板可以具备透射模式和反射模式。图3为图1中半透半反显示面板的透射模式的示意图，图4为图1中半透半反显示面板的反射模式的示意图。
如图3所示，在透射模式下，背光模组14发出的背光能够透过透射区，从而实现彩色显示。背光模组14发出的背光到达形成有反射电极的反射区后不能透过，而是被反射回背光模组14。在本实施例中，反射电极可以包括像素电极112和公共电极113。
如图4所示，在反射模式下，背光模组14关闭，此时照射的光线来自于外部的环境光。环境光照射到反射区的反射电极上而被反射。在反射模式下，可不开启背光模组14，而是采用环境光照明实现显示面板的显示功能，从而达到节约电能的目的。根据本发明的实施例的半透半反显示面板可以在较亮环境中采用反射模式，在较暗环 境中采用透射模式。
在本实施例中，像素电极112和公共电极113交替设置在第一衬底基板111上。根据本实施例的半透半反显示面板为平面转换(In Plane Switching，简称：IPS)型显示面板。此时，像素电极112和公共电极113均位于第一衬底基板11之上，并且像素电极112和公共电极113设置在同一层。
图5为图1中半透半反显示面板的电场强度的示意图。
参见图1和图5，对于IPS型显示面板，相邻的像素电极112和公共电极113之间的电场强度较高，而像素电极112上方的电场强度和公共电极113上方的电场强度均较弱。因此，反射区的电场强度小于透射区的电场强度。由于反射区的电场强度小于透射区的电场强度，因此反射区的横向电场强度小于透射区的横向电场强度。背光通过透射区时经过蓝相液晶一次，环境光照射到反射区并被反射时经过蓝相液晶两次。对于半透半反显示面板而言，通常要求在反射区和透射区的光程差一致。因此，可通过控制反射区的横向电场强度和透射区的横向电场强度来控制反射区和透射区的光程差，从而使得在反射区和透射区的光程差一致。具体地，可通过使反射区的横向电场强度小于透射区的横向电场强度来实现在反射区和透射区的光程差一致的目的，从而无需考虑半透半反显示面板的盒厚问题，降低了制造工艺的复杂度。
根据本发明的实施例，可以在反射电极下方设置凸起结构(未在图中示出)，从而达到增强横向电场的目的。这里的“下方”指的是反射电极背离蓝相液晶的一侧。在本实施例中，由于像素电极112和公共电极113都用作反射电极，因此可以在像素电极112和公共电极113下方设置凸起结构，以增强横向电场。
在图1所示的实施例中，可以在第一衬底基板111上按顺序地设置第一四分之一波片115和第一偏振片114。第一四分之一波片115和第一偏振片114可以设置在第一衬底基板111背离第二基板12的一侧上。可以在第二衬底基板121上按顺序地设置第二四分之一波片123和第二偏振片122。第二四分之一波片123和第二偏振片122可 以设置在第二衬底基板12背离第一基板11的一侧上。
根据本发明的实施例，第一四分之一波片115和第二四分之一波片123的光轴方向可以相互垂直，第一偏振片114的透过轴方向和第二偏振片122的透过轴方向可以相同，第一四分之一波片115的光轴方向和第一偏振片114的透过轴方向的夹角可以为45度，第二四分之一波片123的光轴方向和第二偏振片122的透过轴方向的夹角可以为45度。例如，相对于半透半反显示面板的横向电场的方向，第一偏振片114的透过轴方向可以为45度，第一四分之一波片115的光轴方向为0度，第二四分之一波片123的光轴方向为90度，第二偏振片122的透过轴方向为45度。
下面以半透半反显示面板进行黑态显示的光线变化过程为例，对半透半反显示面板的工作原理进行描述。图6为图1中半透半反显示面板进行黑态显示时透射区的光线变化示意图，图7为图1中半透半反显示面板进行黑态显示时反射区的光线变化示意图。
参见图1和图6，在透射区，背光经过第一偏振片114之后变成第一线偏振光，该第一线偏振光的偏振方向和第一偏振片114的透过轴方向一致。第一线偏振光经过第一四分之一波片115之后变成圆偏振光。由于蓝相液晶13在没有电压驱动的情况下宏观上各向同性，因此圆偏振光经过蓝相液晶13之后不会改变原有的偏振特性，仍然为圆偏振光。圆偏振光经过第二四分之一波片123之后变成第二线偏振光，该第二线偏振光的偏振方向和第二偏振片122的透过轴方向垂直，因此该第二线偏振光不能透过第二偏振片122而无法从半透半反显示面板出射，从而实现在无电压驱动下的黑态显示。
参见图1和图7，在反射区，环境光经过第二偏振片122之后变成第三线偏振光，该第三线偏振光的偏振方向和第二偏振片122的透过轴方向一致。第三线偏振光经过第二四分之一波片123之后变成圆偏振光。由于蓝相液晶13在没有电压驱动的情况下宏观上各向同性，因此圆偏振光经过蓝相液晶13之后不会改变原有的偏振特性，仍然为圆偏振光。圆偏振光经过反射电极的反射并再次经过蓝相液晶13后仍然为圆偏振光。圆偏振光经过第二四分之一波片123之后变成第 四线偏振光，该第四线偏振光的偏振方向和第二偏振片122的透过轴方向垂直，因此该第四线偏振光不能透过第二偏振片122而无法从半透半反显示面板出射，从而实现在无电压驱动下的黑态显示。
根据本实施例的半透半反显示面板无需设置配向膜，从而降低了结构和制造工艺的复杂度。本实施例中，采用蓝相液晶并且像素电极和公共电极均位于第一衬底基板面对第二基板的一侧，从而提高了半透半反显示面板的光学效率。
图8为根据本发明另一实施例的半透半反显示面板的结构示意图，图9为图8中半透半反显示面板的透射模式的示意图，图10为图8中半透半反显示面板的反射模式的示意图，图11为图8中半透半反显示面板的电场强度的示意图。
如图8所示，与前述参照图1至图7描述的实施例的不同之处在于，在本实施例中，第一基板11还可以包括绝缘层116。公共电极113设置在第一衬底基板111与绝缘层116之间，绝缘层116设置在公共电极113与像素电极112之间。下面，针对与前述实施例的差别进行详细描述，而省略了相同部分的描述。
如图9所示，在透射模式下，背光模组14发出的背光能够透过透射区，从而实现彩色显示。背光模组14发出的背光到达形成有反射电极的反射区后不能透过，而是被反射回背光模组14。在本实施例中，反射电极仅包括像素电极112。
如图10所示，在反射模式下，背光模组14关闭，此时照射的光线来自于外部的环境光。环境光照射到反射区的反射电极上而被反射。反射电极仅包括像素电极112。
在本实施例中，像素电极112设置在公共电极113上方，并且在像素电极112与公共电极113之间设置有绝缘层116。根据本实施例的半透半反显示面板为高级超维场转换(ADvanced Super Dimension Switch，简称：ADS)型显示面板。
参见图8和图11，对于ADS型显示面板，像素电极112和公共电极113之间的电场强度较高，而像素电极112上方的电场强度较弱，因此，反射区的电场强度小于透射区的电场强度。由于反射区的电场 强度小于透射区的电场强度，因此反射区的横向电场强度小于透射区的横向电场强度。因此，可通过使反射区的横向电场强度小于透射区的横向电场强度来实现在反射区和透射区的光程差一致的目的，从而无需考虑半透半反显示面板的盒厚问题，降低了制造工艺的复杂度。
类似于前述实施例，可以在反射电极背离蓝相液晶的一侧上设置凸起结构(未在图中示出)，从而达到增强横向电场的目的。在本实施例中，由于仅像素电极112用作反射电极，因此可以在像素电极112背离蓝相液晶的一侧上设置凸起结构，以增强横向电场。
根据本发明的实施例的半透半反显示面板可以应用于半透半反显示装置，该半透半反显示装置还包括背光模组，背光模组位于第一基板背离第二基板的一侧上。背光模组可采用LED光源。
可以理解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不局限于此。对于本领域内的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本发明的保护范围。
