具体实施方式
为使本发明的上述目的、特征和优点能够更加明显易懂，以下结合附图对本发明的具体实施方式进行详细地说明。为便于充分理解本发明，在以下的描述中阐述了很多具体细节，但本发明能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本发明内涵的情况下进行类似改进，因此本发明不受以下公开的具体实施例的限制。

除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。此外，本文所使用的术语“和/或”包括一个或多个相关的所列项目的任意一项或任意组合。
本发明的一个实施例提供了一种显示装置100，其能够实现全屏显示。如图1和图2所示，显示装置100包括本体10、显示屏20、取光模组30、光路结构40及第二显示区50。其中，显示屏20设置在本体10上，显示屏20包括第一显示区21及透光区23，第一显示区21具有背对所述本体10的出光面211；取光模组30位于所述显示屏20与本体10之间；光路结构40及第二显示区50设于所述显示屏20与本体10之间。其中，第一显示区21可以为常规显示区。其中，第二显示区50具有如图1所示的第一状态和如图2所示的第二状态。在第一状态下，所述第二显示区50不发光，自透光区23射入的光线经光路结构40到达取光模组30；具体地，自所述透光区23射入的光线穿过所述光路结构40到达所述取光模组30，或者被所述光路结构40反射给所述取光模组30。在第二状态下，所述第二显示区50发出的光线被所述光路结构50反射至所述透光区23，使所述透光区23显示图像信息，从而实现全屏显示。此外，第二显示区50根据接收到的控制指令切换工作状态，从而实现根据实际需求切换为全屏显示模式。
显示屏20在显示装置100中是用作显示屏幕，显示屏幕仅需要预留透光区 23，其他区域均可以设置为常规显示区，使得显示屏幕的面积与本体10的上表面的面积基本相等，以此来提供具有较高屏占比的显示装置。
在一个实施例中，光路结构40的路径上设置有半反半透结构41及反射结构42。其中，半反半透结构41具有彼此背对的反光面411和透光面412。
一方面，第二显示区50在第一状态下时，所述半反半透结构41的透光面412面对所述透光区23，所述半反半透结构41的反光面411及反射结构42共同作用，从而使得穿过透光面412的光线到达取光模组30。具体地，参照图1和图2所示，自透光区23射入的光线穿透半反半透结构41后，先被反射结构42反射至反光面411，再被反光面411反射至取光模组30。
另一方面，第二显示区50在第二状态下时，所述反光面411相对于第一状态下时的位置翻转180度，并面对透光区23及第二显示区50。在此情况下，反光面411将第二显示区50发出的光线反射至透光区23。
在本实施例中，通过半反半透结构41的翻转实现透光及反光的需求，只需要辅一反射结构42，即可保证取光模组30的采光效果。此外，当设置反射结构42时，自透光区23穿过半反半透结构41的光线经过两次反射后到达取光模组30。取光模组30为摄像头时，摄像头的镜头轴线X与反光面411之间可以成锐角的夹角，在此情况下，可保证取光模组30的采光效果。
取光模组30的镜头轴线X与反光面411之间不需要垂直，同样也可以保证采光效果，从而为取光模组30的布置方式提供了更多的可能。例如，在一个实施例中，取光模组30的镜头轴线X平行于所述显示屏20，反射结构42也平行于显示屏20，第二显示区50在第二状态下时，所述反光面411与所述取光模组30的轴线X之间的夹角为45度，并且，反射结构42也仅需要设置一处，结构简单。
在一个实施例中，光路结构40的路径上也可以是仅设置有半反半透结构41。第二显示区50在第一状态下时，所述半反半透结构41的透光面412面对所述透光区23，自透光区23射入的光线穿透所述半反半透结构41直接到达取光模组30。第二显示区50在第二状态下时，所述反光面411相对于取光模组30第一状态下时的位置翻转180度，并面对透光区23及面对第二显示区50，反光面 411将第二显示区50发出的光线反射至透光区23。
在一个实施例中，光路结构40仅包括半反半透结构41时，取光模组30的镜头轴线X可以垂直于反光面411，以充分接收穿透半反半透结构41的光线。在其他实施例中，取光模组30的镜头轴线X与反光面411之间也可以呈锐角。
光路结构40仅使用半反半透结构41，通过半反半透结构41的翻转，既能实现反射透光区23的光线给取光模组30，又能实现反射第二显示区50的光线给透光区23，且该光路结构40的结构极为简单。
在一个实施例中，半反半透结构41包括透明基板413、及覆盖在透明基板413表面的半反半透膜414。其中，半反半透膜414的工作原理可参照图3所示，正向光线A只能被半反半透膜414反射，而不能穿过半反半透膜414，而反向光线B则可以穿透反半透膜414。
由此，当透明基板413的一侧表面上设置半反半透膜414时，能使得透明基板413的一侧表面形成与透光区及取光模组的镜头相对的反光面411，而透明基板413的另一侧表面则形成允许光线穿过透明基板413的透光面412。
半反半透结构41采用透明基板413涂覆半反半透膜414的方式即可得到。结构简单，且在载体上设置膜层的方式，工艺上易于实现。具体地，透明基板413可采用透明玻璃制得，取材及加工方便，不需要特别制造，简化了制备工作，利于提升制造效率。
在一个实施例中，反光面411在所述显示屏20上的投影覆盖所述透光区23，且反光面411在第二显示区50上的投影覆盖第二显示区50。
第二显示区50在第一状态下时，光线自透光区23射入时，射入的光线能够全部照在反光面411上，进而反光面411将该光线反射给取光模组30，从而保证取光模组30的采光效果。第二显示区50在第二状态下时，能够保证对第二显示区50发出的光线的反射效果，从而保证全屏显示效果。
在一个实施例中，半反半透结构41位于第二显示区50与取光模组30之间。如图5和图6所示，半反半透结构41倾斜45度放置，第二显示区50则竖直放置。反光面411在第二显示区50上的投影覆盖第二显示区50。反光面411在显示屏20上的投影也覆盖透光区23，以此来保证不漏光，及反射效果。
在一个实施例中，所述取光模组30为摄像头，摄像头的镜头轴线X平行于所述显示屏20，所述第二显示区50同时垂直于所述取光模组的镜头轴线X及所述显示屏20，第二显示区50在第二状态下时，所述反光面411与所述取光模组的镜头轴线X之间的夹角为45度。在此情况下，当第二显示区50在第二状态下时，取光模组30关闭时，第二显示区50射向反光面411的光线以90度反射角反射至透光区23。即，光线到达透光区23时垂直于显示屏20，从而使得透光区23的显示方式与第一显示区21的显示方式一致，提高了全屏显示的整体视觉效果。
如图6所示，第二显示区50射向反光面411的光线水平向右，被反光面411反射后垂直向上射向透光区23。
在一个实施例中，如图4所示，显示装置100还包括控制所述半反半透结构41翻转的驱动机构60、控制所述驱动机构60的执行控制模块70。
在一实施例中，所述执行控制模块70根据所述取光模组30的工作或关闭信号控制所述驱动机构60工作。通过设置驱动机构60，实现半反半透结构41根据取光模组30的工作情况进行自动化翻转，使得显示装置在取光模组30不工作的情况下，能够自动切换为全面屏显示。
在一个实施例中，驱动机构60可以采用伺服电机及翻转推板。执行控制模块70通过控制伺服电机的输出轴的正转和反转，实现半反半透结构41的翻转。进一步地，执行控制模块70通过控制伺服电机的输出轴的转动圈数，控制半反半透结构41翻转的精度。
在一个实施例中，第二显示区50为OLED(Organic Electroluminesc ence Display,OELD)显示屏，即有机电致发光显示屏。其中，OLED显示屏具有自发光特点、亮度高、显示效果好等优点。
在一个实施例中，显示屏20的第一显示区21为单侧发光的OLED显示屏。第二显示区50的出光面朝向所述光路结构40。
在一个实施例中，如图5和图6所示，所述第二显示区50是底发光型OLED显示屏。此时，第二显示区50的端部位于透光区23的一侧，第二显示区50的除该端部以外的剩余部分容纳在本体10的容纳空腔11内部。进一步地，底发 光型OLED显示屏的可以设置为一端部与第一显示区21平齐，以此保证衔接区显示效果，然后弯折90度，即第二显示区50被弯折的端部位于透光区23的一侧，第二显示区50的剩余部分容纳在本体10的容纳空腔11内部。
OLED显示屏的厚度非常薄，在此情况下，虽然第二显示区50的端部延伸至透光区23的一侧，但对于显示装置100的整个显示屏幕而言，此厚度可以忽略不计，相较于显示屏幕旁边必须具有较大的黑边的传统显示装置，本发明各实施例提供的显示装置100的整个显示屏幕仍呈现全面屏的效果。
在一个实施例中，如图5和图6所示，所述第二显示区50为顶发光型结构的OLED显示屏时，所述第二显示区50的出光面朝向所述光路结构40，可以做到第二显示区50整体位于显示屏一侧，且第二显示区50全部容纳所述本体10的容纳空腔11内，从而不影响设备的厚度及美感。
在一个实施例中，所述第二显示区50不限于为OLED显示屏，也可以是其他类型的显示屏，例如液晶显示屏、Micro-Led、CRT、或是等离子屏等。
如图5所示，第二显示区50在第一状态下，第二显示区50不发光，穿过半反半透结构41的光线被反射给取光模组30。如图6所示，第二显示区50在第二状态下，半反半透结构41翻转180度，第二显示区50发光，第二显示区50发出的光线被半反半透结构41反射至透光区23，实现对透光区23的补偿，使透光区23显示图像信息，从而实现全屏显示。
在一个实施例中，前文所述的光路结构40及取光模组30、第二显示区50也可以设置为均位于容纳空腔11的内部，从而不影响设备的厚度及美感。
本发明各实施例提供的显示装置100可以为手机、电脑或电视等。在一个实施例中，本体10可以是移动终端(例如手机)的壳体，显示屏20安装在本体上构成手机的正面。在其他的实施例中，本体10可以是其他显示设备的主机壳体，例如，本体10为平板电脑的主机壳体。
在一个实施例中，透光区23为通孔，且通孔中安装有聚光镜片24。由于设置了采用聚光镜片24，提高取光模组30的采光效果，能够保证成像效果。
此外，在本发明各实施例中，透光区23在显示屏20上的位置不作具体限定。通常，透光区23设置在靠近显示屏20的边缘，从而不影响第一显示区21 的显示。
在一个实施例中，第二显示区50根据取光模组30的启动或关闭进行工作状态的切换，从而实现根据取光模组30的工作情况，进行全屏显示模式的自动切换。
在一个实施例中，显示装置100包括执行控制模块70。执行控制模块70包括检测单元71和驱动电路控制单元72，其中，检测单元71用于实时检测取光模组30是否开启，驱动电路控制单元72用于根据取光模组30的驱动信号控制第二显示区50处于工作状态或处于不工作状态。当取光模组70关闭时，驱动电路控制单元72控制第二显示区50发光用以显示，取光模组30开启时，驱动电路控制单元72控制第二显示区50终止显示。通过设置执行控制模块70，实现取光模组30关闭时，第二显示区50发光并对透光区23进行补偿，从而实现全屏显示。
在一个实施例中，取光模组30开启时，驱动电路控制单元72断开对第二显示区50的供电。当取光模组30关闭时，驱动电路控制单元72恢复对第二显示区50的供电。
在一个实施例中，取光模组30开启时，驱动电路控制单元72关闭扫描行中对应第二显示区50的数据线，以使第二显示区50终止显示关联的应用程序。当取光模组30关闭时，驱动电路控制单元72开启扫描行中对应第二显示区50的数据线，使第二显示区50显示其关联的应用程序。第二显示区50显示其关联的应用程序时，观看者即可观看到显示图像。
以上各实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上各实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
