附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是本发明实施例提供的一种显示面板的结构示意图；
图2是图1提供的显示面板中OLED面板和反射式LCD面板的一种结构示意图；

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。
图1是本发明实施例提供的一种显示面板的结构示意图，参见图1，显示面板包括：有机发光二极管OLED面板100、设置在OLED面板100上的反射式液晶显示器LCD面板200、以及驱动电路300；驱动电路300用于根据控制信号驱动OLED面板100或反射式LCD面板200进行显示。
本发明通过将OLED面板100和反射式LCD面板200设置在一起，并通过驱动电路300控制OLED面板100或反射式LCD面板200进行显示，解决了现有显示器件显示方式较为单一的问题。
再次参见图1，该显示面板还可以包括：与驱动电路300连接的控制模块400；控制模块400，用于获取用户输入指令；根据用户输入指令生成控制信号；或者，获取外部环境光的亮度；根据外部环境光的亮度生成控制信号。也就是说，在本发明中，控制模块400根据用户输入或者外部环境光来生成控制信号，将控制信号传输给驱动电路300，从而控制OLED或LCD进行显示，实现OLED和LCD显示的切换；上述两种控制信号生成方式，分别能够实现该显示面板的手动或者自动控制。
当控制模块400根据外部环境光的亮度生成控制信号时，该显示面板还可以包括：光感应传感器，控制模块400与光感应传感器连接，光感应传感器用于检测外部环境光的亮度；控制模块400，用于当外部环境光的亮度大于或等于设定值时，生成控制反射式LCD面板200显示的控制信号；当外部环境光的亮度小于设定值时，生成控制OLED面板100显示的控制信号。
由于反射式LCD面板200可以利用环境光反射作为背光源，因此在外部环境光亮度较高时，采用反射式LCD面板200进行显示，反射式LCD面板200没有背光源，节省了背光源所需能量，功耗低；而当外部环境光亮度较低时，可以采用OLED面板100进行显示，避免只采用反射式LCD面板200时，显示面板在这种情况下无法显示；采用这种反射式LCD面板200和OLED面板100结合的显示方式，使得显示面板在可以在环境光亮度高时间采用反射式LCD面板200显示，其余时间内采用OLED面板100显示，使得平均功耗低于普通LCD和OLED的功耗。
当控制模块400根据用户输入指令生成控制信号时，该显示面板还可以包括：用户输入模块，控制模块400与用户输入模块连接，用户输入模块用于将用户输入信号传输给控制模块400。控制模块400包括控制开关、键盘、触控面板等部件中的至少一个。
图2是图1提供的显示面板中OLED面板100和反射式LCD面板200的一种结构示意图，参见图2，OLED面板100包括基板101，依次设置在基板101上的阳极102、发光层103和阴极104，以及设置在基板101上且包裹阳极102、发光层103和阴极104的封装层105；反射式LCD面板200包括像素电极201、上基板202以及设置在像素电极201和上基板202之间的液晶203，像素电极201设置在封装层105上；OLED面板100的阴极104为反射式LCD面板200的反射层。将反射LCD的反射层与OLED的阴极104复用，节省材料，降低显示面板厚度。
采用上述结构制成的OLED面板100既可以是顶发射型OLED(发出的光是从器件的顶部出射)，也可以是底发射型OLED(发出的光是从器件的底部出射)。
其中，阳极102可以包括依次设置在基板101上的氧化铟锡(Indium Tin Oxide，简称ITO)走线层、银(Ag)反射层和ITO电极层。其中，ITO走线层和ITO电极层也可以采用氧化铟锌(Indium Zinc Oxide，简称IZO)走线层和IZO电极层等代替。
其中，阴极104可以采用银、银镁(Mg)合金等材料制成。
其中，像素电极201可以由透明导电材料制成，例如可以是ITO或IZO薄膜电极。
其中，封装层105为透明绝缘层，例如氮化硅层、树脂层等，在实现绝缘保护的同时增强透光性。
其中，上基板202为彩膜基板，彩膜基板通常包括衬底基板、色阻层和黑矩阵等结构。
在本发明实施例中，当反射式LCD面板200为平面转换IPS型或高级超维场转换ADS型LCD面板200时，驱动电路300用于在反射式LCD面板200显示时，向阳极102输入公共信号，在OLED面板100显示时，向阳极102输入阳极信号。将LCD的公共电极与OLED的阳极102复用，减小显示面板厚度，节省材料。
在本发明实施例中，基板101可以包括衬底基板和设置在衬底基板上的TFT电路，TFT电路分别与像素电极201、阳极102和驱动电路300连接。TFT电路同时与像素电极201、阳极102和驱动电路300连接，实现一个TFT电路同时控制OLED面板100和反射LCD面板200，省去了反射LCD中的TFT电路，减小了显示面板厚度。
其中，衬底基板可以是玻璃基板、塑料基板、硅基板等。
其中，TFT电路可以包括：多根平行设置的栅线、多根平行设置的数据线、多个第一晶体管、多个选择电路和多个第二晶体管。图3为本发明实施例提供TFT电路的电路图(仅显示了TFT电路的一部分)，如图3所示，TFT电路中栅线gate和数据线data交叉设置，每根栅线和数据线交叉处设置一个第一晶体管T1、一个选择电路101A和一个第二晶体管T2，第一晶体管T1的栅极连接栅线，第一晶体管T1的源极连接数据线，第一晶体管T1的漏极连接选择电路101A的输入端111，选择电路101A的第一输出端112连接第二晶体管T2的栅极，选择电路101A的第二输出端113连接LCD的像素电极201，选择电路101A的控制端114用于在控制信号的作用下接通输入端111和第一输出端112或者第二输出端113，第二晶体管T2的源极连接电源电压Vdd，第二晶体管T2的漏极连接OLED的阳极102(图未示出)，栅线、数据线和选择电路101A的控制端114均与驱动电路300连接。通过在TFT电路中加入选择电路101A，从而选择OLED和LCD面板200中的一个进行显示，省去了反射LCD中的TFT电路，减小了显示面板厚度。
图4为本发明实施例提供的选择电路的电路图，如图4所示，选择电路101A包括P型金属氧化物半导体场P-MOS晶体管T3和N型金属氧化物半导体N-MOS晶体管T4，P-MOS晶体管T3和N-MOS晶体管T4的栅极(选择电路101A的控制端)同时连接控制信号，P-MOS晶体管T3和N-MOS晶体管T4的源极(选择电路101A的输入端)同时连接第一晶体管T1的漏极，N-MOS晶体管T4的漏极(选择电路101A的第二输出端)连接像素电极201(属于LCD)，P-MOS晶体管T3的漏极(选择电路101A的第一输出端)连接第二晶体管T2(属于OLED)的栅极。采用P-MOS晶体管T3和N-MOS晶体管T4实现选择电路101A，实现不同控制信号导通不通P-MOS晶体管T3或N-MOS晶体管T4，进而选择OLED和LCD面板200中的一个进行显示。
再次参见图2，显示面板还包括设置在封装层105外部的走线106A。TFT电路与像素电极201通过走线106A连接。图5是本发明实施例提供的显示面板的俯视图，参见图5，像素电路201通过走线106A与OLED面板100的TFT电路电连接，驱动电路300通过信号线301与OLED面板100电连接。
图6是图1提供的显示面板中OLED面板100和反射式LCD面板200的另一种结构示意图，图6所示的结构与图2相比，区别在于封装层105上设有过孔106B，TFT电路与像素电极201通过过孔106B连接，而不需要通过外部走线连接TFT电路与像素电极201。
在图2和图6所示的显示面板中，反射式LCD面板200均设置在OLED面板100的封装层105上，一方面方便显示面板的制作，另一方面方便走线。当然，也可以将反射式LCD面板200设置在OLED面板100的基板101上，这里不做赘述。
在本发明实施例中，反射式LCD面板200还可以包括封框胶204，封框胶设置在像素电极201和上基板202之间。
在本发明实施例的一种实现方式中，反射式LCD面板200还可以包括取向层205，取向层205设置在上基板202和像素电极201之间，且在像素电极201和上基板202上分别设置有一取向层，取向层205用于实现液晶203取向。在本发明实施例的另一种实现方式中，还可以通过在液晶203中掺杂高分子聚合物实现液晶取向。
在本发明实施例中，反射式LCD面板200还可以包括柔性基板206，柔性基板206用于将制备好的反射式LCD面板直接贴合到OLED面板100上。柔性基板206为聚酰亚胺等柔性材料制成的基板。柔性基板206的厚度小于10微米，相位延迟量Rth小于100，透过率大于75％，按上述要求设计的柔性基板206透过好，不易窜色。
本发明实施例还提供了一种显示装置，显示装置包括图1提供的显示面板。
在具体实施时，本发明实施例提供的显示装置可以为手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
本发明通过将OLED面板和反射式LCD面板设置在一起，并通过驱动电路控制OLED面板或反射式LCD面板进行显示，解决了现有显示器件显示方式较为单一的问题。
图7是本发明实施例提供的一种显示面板制作方法的流程图，该方法用于制作权利要求图1所示的显示面板，参见图7，该方法包括：
步骤501：在OLED面板上设置反射式LCD面板。
步骤502：将OLED面板和反射式LCD面板与驱动电路电连接，驱动电路用于根据控制信号驱动OLED面板或反射式LCD面板进行显示。
本发明通过将OLED面板和反射式LCD面板设置在一起，并通过驱动电路控制OLED面板或反射式LCD面板进行显示，解决了现有显示器件显示方式较为单一的问题。
在本发明实施例的一种实现方式中，步骤501可以包括：
第一步：制作反射式LCD面板，反射式LCD面板包括衬底基板。
第二步：将反射式LCD面板的衬底基板剥离后，贴合到OLED面板上。
即先分别制作OLED面板和反射式LCD面板，然后组合到一起，制作工序复杂度较低。
其中，制作LCD面板包括：制作下基板；制作上基板；将下基板和上基板进行对盒。
其中，制作下基板可以包括：提供一衬底基板、在衬底基板上制作柔性基板、在柔性基板上制作像素电极。制作上基板可以包括：提供一衬底基板、在衬底基板上制作色阻层、黑矩阵等结构。将下基板和上基板进行对盒可以包括：取向层制备与取向；间隔物散布与固着；封框胶制备等。
在制作反射式LCD面板前，该方法还包括制作OLED面板。制作OLED面板可以包括：制作基板；在基板上依次制作阳极、发光层、阴极和封装层。
在该实现方式中，步骤502可以包括：
在将反射式LCD面板贴合到OLED面板上后，通过设置在OLED面板的封装层外部的走线连接反射式LCD面板的像素电极和OLED面板上的TFT电路，TFT电路与驱动电路连接。通过外部走线实现驱动电路与像素电极连接。
在本发明实施例的另一种实现方式中，步骤501可以包括：
在OLED面板上制作反射式LCD面板。
上述制作方法，先制作OLED面板，然后在OLED面板上制作反射式LCD面板，制作工序少，减少制作用时。
其中，在OLED面板上制作反射式LCD面板包括：在OLED面板上制作像素电极；制作上基板；将OLED面板和上基板进行对盒。制作上基板可以包括：提供一衬底基板、在衬底基板上制作色阻层、黑矩阵等结构。
在该实现方式中，反射式LCD面板中的液晶采用聚合物掺杂方式实现取向。由于反射式LCD面板中液晶采用聚合物掺杂方式实现取向，避免采用常规取向工艺造成的高温对OLED面板的破坏。
所以，将OLED面板和上基板进行对盒可以包括：采用聚合物掺杂方式进行取向；间隔物散布与固着；封框胶制备等。
在该实现方式中，步骤502可以包括：
在制作反射式LCD面板后，通过设置在OLED面板的封装层外部的走线连接反射式LCD面板的像素电极和OLED面板上的TFT电路；或者，在制作反射式LCD面板前，在OLED面板上制作过孔，在制作反射式LCD面板时，将反射式LCD面板的像素电极通过过孔与OLED面板上的TFT电路连接；TFT电路与驱动电路连接。通过外部走线连接或过孔连接实现驱动电路与像素电极连接。
在本发明实施例中，外部走线通过绑定(bonding)方式(如图5所示)，或者喷墨(inkjet)方式打印导电银胶实现。

步骤601：获取控制信号。
步骤602：根据控制信号驱动OLED面板或反射式LCD面板进行显示。
本发明通过将OLED面板和反射式LCD面板设置在一起，并通过驱动电路控制OLED面板或反射式LCD面板进行显示，解决了现有显示器件显示方式较为单一的问题。
在本发明实施例的一种实现方式中，获取控制信号可以包括：
获取用户输入指令；根据用户输入指令生成控制信号；或者，
获取外部环境光的亮度；根据外部环境光的亮度生成控制信号。
根据用户输入或者外部环境光来实现OLED和LCD显示的切换，实现显示面板的手动或自动控制。
其中，根据外部环境光的亮度生成控制信号可以包括：
当外部环境光的亮度大于或等于设定值时，生成控制反射式LCD面板显示的控制信号；当外部环境光的亮度小于设定值时，生成控制OLED面板显示的控制信号。
由于反射式LCD面板可以利用环境光反射作为背光源，因此在外部环境光亮度较高时，采用反射式LCD面板进行显示，反射式LCD面板没有背光源，节省了背光源所需能量，功耗低；而当外部环境光亮度较低时，可以采用OLED面板进行显示，避免只采用反射式LCD面板时，显示面板在这种情况下无法显示；采用这种反射式LCD面板和OLED面板结合的显示方式，使得显示面板在可以在环境光亮度高时间采用反射式LCD面板显示，其余时间内采用OLED面板显示，使得平均功耗低于普通LCD和OLED的功耗。
进一步地，该方法还可以包括：当反射式LCD面板为IPS型或ADS型LCD面板时，在反射式LCD面板显示时，向阳极输入公共信号，在OLED面板显示时，向阳极输入阳极信号。将LCD的公共电极与OLED的阳极复用，减小显示面板厚度，节省材料。
以上仅为本发明的较佳实施例，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
