以下各实施例的说明是参考附加的图示，用以例示本申请可用以实施的特定实施例。本申请所提到的方向用语，例如[上]、[下]、[前]、[后]、[左]、[右]、[内]、[外]、[侧面]等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本申请，而非用以限制本申请。在图中，结构相似的单元是用以相同标号表示。
首先对现有技术进行简要说明。参见图1，现有技术中的显示面板包括显示区AA’，所述显示区AA’包括多个像素单元。图1示例性的示出一个像素单元的示意图，其中，每个像素单元包括第一子像素01、第二子像素02和第三子像素03。所述第一子像素01、第二子像素02和第三子像素03分别发出红光、蓝光和绿光。在显示时，每一个像素单元同一时间只能发出一种颜色的光，因此现有技术中的显示面板的开口率只有33%左右，亟待提高。
因此，本申请提供了一种组合式显示面板，以提高现有技术中的显示面板的开口率。
参见图2、图3和图4，图2为本申请的一个具体实施例中的组合式显示面板的第一子屏D1的结构示意图，图3为本申请的一个具体实施例中的组合式显示面板的第二子屏D2的结构示意图，图4为由图2和图3中的第一子屏D1和第二子屏D2构成的组合式显示面板的结构示意图。
本申请中的组合式显示面板包括第一子屏D1和第二子屏D2。参见图2，所述第一子屏D1包括多个第一像素单元P1，每一个所述第一像素单元P1包括第一子像素10和第三子像素30。参见图3，所述第二子屏D2包括多个与所述第一像素单元P1对应设置的第二像素单元P2，每一个所述第二像素单元P2包括第二子像素20。
参见图4，所述第一子屏D1与所述第二子屏D2重叠设置，每一个所述第二像素单元P2位于与之对应的第一像素单元P1正上方，所述第一像素单元P1和第二像素单元P2层叠构成所述组合式显示面板的像素单元。
在本实施例中，为了使所述第一像素单元P1和第二像素单元P2能够在所述第一子屏D1与所述第二子屏D2重叠设置之后完全重叠构成所述组合式显示面板的像素单元，所述第二像素单元P2的形状和面积与所述第一像素单元P1的形状和面积相同。本实施例中，所述第一像素单元P1和第二像素单元P2的形状为矩形，但也不限于其他形状。
在本实施例中，所述第一子像素10为红色像素，所述第二子像素20为蓝色像素，所述第三子像素30为绿色像素。所述第一子像素10的面积等于所述第三子像素30的面积。由于蓝光的波长较短，蓝色像素点的功耗较大，导致蓝色像素中的薄膜晶体管和发光二极管的损耗较高，比红色像素点和绿色像素点更容易老化。现有技术中，由于蓝色像素的老化速度较快，因此蓝色像素的寿命决定了显示面板的寿命。本发明的显示面板将蓝色像素作为第二子像素20，单独占据所述第二像素单元P2，使得蓝光的开口率接近100%，大幅度降低了蓝色像素点的功耗。因此，本申请的显示面板显著的减缓了蓝色像素的老化，从而延长了显示面板的使用寿命。
在本实施例中，所述第一子屏D1为上发光显示屏，所述第二子屏D2为双面发光显示屏。重叠设置构成组合式显示屏之后，所述第二子屏D2为上发光显示屏。所述第一子屏D1的阳极为反射电极，阴极为透明电极。所述第二子屏D2的阳极为透明电极，阴极为透明电极。所述反射电极可以是金属电极，例如银、铜、金等具有良好的导电性和反射率的导电金属。所述透明电极可以是氧化铟锡等透明导电材料。
在本实施例中，所述第一子屏D1包括第一显示区AA-1和第一非显示区AA-1’。所述多个第一像素单元P1被设置在所述第一显示区AA-1上。所述第一非显示区AA-1’与所述第一显示区AA-1相邻设置，用于设置第一控制电路，所述第一控制电路用于控制所述第一显示区AA-1的显示。所述第二子屏D2包括第二显示区AA-2和第二非显示区AA-2’，所述多个第二像素单元P2被设置在所述第二显示区AA-2上，所述第二非显示区AA-2’与所述第二显示区AA-2相邻设置，用于设置第二控制电路，所述第二控制电路用于控制所述第二显示区AA-2的显示。
在本实施例中，所述第一子屏D1和第二子屏D2为矩形。所述第一非显示区AA-1’沿着所述第一子屏D1的一条侧边设置。所述第二非显示区AA-2’沿着所述第二子屏D2的一条侧边与所述第一非显示区AA-1’对应设置，所述第二非显示区AA-2’的形状和面积与所述第一非显示区AA-1’相同。所述第一子屏D1和第二子屏D2的控制信号相同，所述第一像素单元P1和与其对应的第二像素单元P2接收的显示信息相同。
参见图2和图3，所述第一子屏D1上的多个第一像素单元P1的分布图案与所述第二子屏D2上的多个第二像素单元P2的分布图案轴对称。参见图4，重叠设置时，所述第二子屏D2沿所述对称轴翻转覆盖所述第一子屏D1。本实施例中的组合式显示屏的两个非显示区分别位于显示区的两侧。由于非显示区上方没有遮挡，本实施例中的第一子屏D1和第二子屏D2更加易于组合。但同时所述组合式显示屏的屏占比也相对较小。
参见图2，图5和图6，在本发明的另一个实施例中，所述第一子屏D1上的多个第一像素单元P1的分布图案与所述第二子屏D2上的多个第二像素单元P2的分布图案一致。重叠设置时，所述第二子屏D2水平平移覆盖所述第一子屏D1。本实施例中的组合式显示屏的两个非显示区位于显示区的同一侧。相比于前一个实施例，本实施例中的第一子屏D1和第二子屏D2的组合难度较大。但同时所述组合式显示屏的屏占比也相对较大，显示效果较好。在实际中可根据需要选择合适的方案。
在本申请的实施例中，所述组合式显示面板还包括位于所述第一子屏D1和第二子屏D2之间的多个支撑柱40。所述支撑柱40的高度相同，一方面用于支撑所述第二子屏D2，分散所述第二子屏D2施加到第一子屏D1上的压力，避免第一子屏D1因为受力不均产生裂纹。另一方面也能够保证所述第一子屏D1和第二子屏D2之间的距离保持恒定，避免由于所述第一子屏D1和第二子屏D2之间的距离改变导致的像素单元偏移。优选的，为了避免所述支撑柱40在显示面板上形成光斑或阴影，形成所述多个支撑柱40的材料为白色材料或透明材料，所述多个支撑柱40表面具有漫反射结构。
本申请提供的组合式显示面板包括对应设置的第一子屏和第二子屏。所述第一子屏包括多个第一像素单元，所述第二子屏包括多个与所述第一像素单元对应设置的第二像素单元。每一个所述第一像素单元包括第一子像素和第三子像素，每一个所述第二像素单元包括第二子像素。每一个所述第二像素单元位于与之对应的第一像素单元正上方。采用这种设置，当所述第一子像素或第三子像素发光时，所述组合式显示面板的像素单元的开口率接近50%。当所述第二子像素发光时，所述组合式显示面板的像素单元的开口率接近100%。因此，本申请极大的提高了显示面板的开口率，优化了显示面板的显示效果。
综上所述，虽然本申请已以优选实施例揭露如上，但上述优选实施例并非用以限制本申请，本领域的普通技术人员，在不脱离本申请的精神和范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为准。
