本申请要求于2015年04月29日递交的中国专利申请第201510211989.5号的优先权，在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
技术领域
本发明实施例涉及显示领域，尤其涉及一种显示面板及显示装置。
背景技术
目前，液晶显示装置根据其所利用光源的原理不同，可分为透射式液晶显示装置和反射式液晶显示装置。其中，透射式液晶显示装置通常需要在液晶显示面板背面设置背光源以提供照明，但由于背光源能耗高，故导致透射式液晶显示装置能耗大，且在环境光强的时候，液晶显示面板的对比度差，显示效果差；而反射式液晶显示装置可以不需要背光源，因此其能耗较低，比较适合在环境光强的情况下使用，但在环境光较弱时其显示品质会变差。
上述两种模式的显示装置只能在特定的环境条件下才能有较好的显示品质，而随着人们对显示产品要求的提高，亟需一种能够适应不同环境条件的显示产品。

具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。
本发明实施方式提供了一种显示面板，该显示面板包括依次层叠设置的第一基板、液晶层、第二基板以及偏光片；
所述第一基板上设置有光反射层和多个有机发光单元，其中所述多个有机发光单元位于所述光反射层的靠近所述液晶层一侧；
所述第二基板用于控制所述液晶层中液晶分子的偏转，所述第二基板包括多个子像素区域。
本发明实施方式提供的显示面板，通过对输入到第一显示基板和第二显示基板上的显示信号的控制，可以根据需要使显示面板在两种显示模式之间切换。例如，当将显示信号输入第一基板时，能够实现该显示面板的透射式显示，当将显示信号输入第二基板时，能够实现该显示面板的反射式显示。
参见图1，图1是本发明实施方式提供的一种显示面板的示意图，该显示面板包括依次层叠设置的第一基板100、液晶层200、第二基板300以及偏光片400，液晶层200的上下两侧还可设置有取向层(图中未示出)。例如，液晶层200设置在第一基板100之上，第二基板300设置在液晶层200之上，偏光片400设置在第二基板300之上。
在一个实施例中，该第一基板100可以为OLED基板，其上设置有呈矩阵排布的多个有机发光单元，每一个有机发光单元均设有对应的薄膜晶体管(TFT)。当将显示信号输入该第一基板时，其上的有机发光单元根据该输入的显示信号呈现不同的明暗状态，从而显示对应的画面。
进一步地，在每一个有机发光单元远离液晶层的一侧还设置有光反射层，该光反射层用于反射来自于外界的自然光，以使该反射光用作根据本发明实施例的显示面板的背光。
该第二基板300用于控制液晶层中液晶分子的偏转，该第二基板300包括多个子像素区域。在一个实施例中，第二基板上设置有相互交错的栅线和数据线，并且通过多条栅线和数据线将该第二基板划分为多个子像素区域。在一个实施例中，每一个子像素区域上均设有TFT以及与TFT相连并且透明的电极结构，通过该电极结构产生的电场能够控制液晶层中对应区域中的液晶分子的偏转状态，进而可以控制通过液晶层中该区域的光的偏振状态。可以理解，其他实施例也是可行的。
本发明实施例提供的显示面板既可以实现透视式显示，也可以实现反射式显示，如以上实施例所描述的或如下将进一步详细描述的。
具体地，当将显示信号输入第一基板100时，如图2所示，第一基板通过其上的有机发光单元发光，并且由于该第一基板发出的光为自然光，因此能够依次透过液晶层200、第二基板300以及偏光片400后出射，从而实现该显示面板的透射式显示；
而当将显示信号输入第二基板300时，此时，第一基板100不工作，第二基板300上各个子像素区域上的电极结构根据该输入的显示信号产生不同的电场，使得液晶层中不同区域中的液晶分子呈现不同的偏转状态，从而控制经过液晶层的光的偏振状态。具体地，以在第二基板上设置产生水平模式电场的电极结构为例，当该偏光片的透光轴为x方向时，从外界射入的自然光透过偏光片400形成x方向的线偏振光，而后入射至液晶层200，当子像素区域中的电极结构不产生电场时，液晶层中的液晶分子的状态不发生变化，该位置处的液晶层200不改变透过其中的线偏振光的状态，因此，该x方向的线偏振光透过液晶层200后仍为x方向的线偏振光，而后经第一基板100上的光反射层将该x方向的线偏振光再次反射至液晶层200，并且经过该液晶层200后仍为x方向的线偏振光，从而能够透过偏光片400出射，实现该子像素区域呈现亮态显示；当子像素区域中的电极结构产生水平电场时，对应位置处的液晶层中的液晶分子在该电场的作用下旋转，其扭转角度满足双折射条件，使得入射至该液晶层中的线偏振光通过该液晶层后变成圆偏振光，例如，如图4所示，经过偏振片400产生的x方向的线偏振光在透过液晶层200后形成左旋圆偏振光，而后经过第一基板100上的光反射层将入射的左旋圆偏振光反射形成右旋圆偏振光，该右旋圆偏振光再次透过液晶层300后形成y方向的线偏振光，由于该y方向的线偏振光不能通过偏振片400，因此实现该子像素区域的暗态显示。
由此可见，当显示信号输入到第一基板时，可以实现显示面板的透射式显示；当显示信号输入到第二基板时，通过控制第二基板上的电极结构产生的电场的方向来控制第二基板的子像素区域的明暗状态，从而实现显示面板的反射式显示。
在一个实施例中，如图7所示，显示面板还可以包括控制单元，通过该控制单元来控制显示信号到第一基板和第二基板的输入，当将显示信号输入到第一基板时，显示面板在第一显示模式下工作；当将显示信号输入到第二基板中，显示面板在第二显示模式下工作。在一个示例中，第一显示模式为透射式显示模式，第二显示模式为反射式显示模式。
在一个实施例中，上述的光反射层可以单独制作在第一基板上。在另一个实施例中，可以复用第一基板上的有机发光单元中的电极层作为光反 射层，即光反射层和第一基板上的有机发光单元中的电极层为同一结构。如图5所示，第一基板100上的每个有机发光单元包括衬底110、有机发光层130、设置在所述有机发光层130靠近所述液晶层一侧的第一电极层140、设置在所述有机发光层130远离所述液晶层一侧的第二电极层120，其中，第一电极层140可以采用透明导电材料，例如ITO等，第二电极层120可以采用导电且反光性较好的金属材料，例如可以为银、铝等，使得该第二电极120即可以作为控制有机发光层发光的电极结构，又同时作为光发射层。
根据本发明实施例提供的的显示面板，由于当处于透射模式时，第一基板发出的光需要通过第二基板，因此，为了提高显示效果，在一个实施例中，可以使得第二基板上的子像素区域与第一基板上的有机发光单元的形状及大小均相同。进一步地，可以使第二基板上的子像素区域与第一基板上的有机发光单元一一正对设置。其他实施例也是可行的。
在一个示例中，为了实现该显示面板能够实现彩色显示，第一基板100上的有机发光单元可以为彩色的有机发光单元。具体地，可以在第一基板设置至少三种颜色(如红色R、绿色G和蓝色B)的有机发光单元，并且使得该至少三种颜色的有机发光单元在第一基板上呈周期性重复排列，当该显示面板处于透射显示模式时，其为彩色显示，当处于反射显示模式时，其可以实现黑白显示。
在另一个示例中，第一基板100上的有机发光单元还可以均为白色有机发光单元(即该第一基板100为WOLED基板)，为了进一步地使该显示面板能够实现彩色显示，还可以在其中增设彩膜基板。参见图6，图6是本发明实施方式提供的另一种显示面板的示意图，该显示面板包括依次层叠设置的第一基板100、液晶层200、第二基板300以及偏光片400，液晶层200的上下两侧还可设置有取向层(图中未示出)。
在该实施例中，该第一基板100为WOLED基板，其上设置有呈矩阵排布的多个白色有机发光单元，并且在每一个有机发光单元远离液晶层的一侧还设置有光反射层。
第二基板300用于控制所述液晶层中液晶分子的偏转，其包括多个子像素区域，并且第二基板300上的子像素区域与第一基板200上的有机发 光单元一一正对设置。
此外，在第一基板100的发光侧还设置有第三基板500，该第三基板500包括多个彩色滤光单元，并且第三基板上的彩色滤光单元与所述第一基板上的有机发光单元一一正对设置，且两者的大小以及形状均相同。
在该实施例中，该第三基板500包括至少三种颜色的彩色滤光单元，且所述至少三种颜色的彩色滤光单元在所述第三基板上呈周期性重复排列，例如，该第三基板可以包括红色滤光单元、绿色滤光单元和蓝色滤光单元，从而实现RGB模式的显示面板。
在一个示例中，为了减少相邻子像素之间的串色，所述第三基板还包括将所述多个彩色滤光单元之间相互分隔的黑矩阵层。
本实施方式中的显示面板，其显示原理与图1中的显示面板相同，此处不再赘述，本实施方式通过在第一基板的发光侧增设第三基板，通过第三基板可以将白光转换为对应颜色的彩色光，从而可以实现该显示面板的彩色显示。
在一个实施例中，为了进一步地降低相邻子像素之间的串色，提高显示效果，可以将该第三基板靠近显示面板的显示侧设置，例如，可以将第三基板设置在第二基板的远离液晶层的一侧。
如上所述，本发明实施方式提供的显示面板，能够实现在透射显示模式与反射显示模式之间的切换，当在环境光线较差的条件下，可以将显示信号输入第一基板，从而实现该显示面板的透射式显示；当在环境光线较强的条件下，可以将显示信号输入第二基板时，实现该显示面板的反射式显示。通过上述方式在不同模式下切换，不但能够提高降低能耗，还能提高显示品质。
在另一方面，本发明实施方式还提供了一种显示装置，包括上述的显示面板。其中，本发明实施方式提供的显示装置可以是笔记本电脑显示屏、电视、数码相框、手机、平板电脑等任何具有显示功能的产品或部件。

表述“具有”、“包括”和“包含”及其语法变体以非排他性的方式使用。因此，表述“A具有B”以及表述“A包括B”或“A包含B”可以 都指如下事实，即除了B之外，A还包含一个或多个另外的组件和/或构成要素，以及如下情况，其中除了B之外，没有其它组件、构成要素或元件在A中呈现。
术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性。
