本发明的实施方式
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和图3,图2为本申请的一个具体实施例中的折叠式显示面板处于展开状态时的结构示意图,图3为图2中的折叠式显示面板处于折叠状态时的结构示意图。
本申请中的折叠式显示面板包括第一显示区AA-1、第二显示区AA-2和折叠区AA-3。参见图2,所述第一显示区AA-1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。所述第二显示区AA-2与所述第一显示区AA-1为轴对称图形,所述第二显示区AA-2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,所述第二像素单元P2包括第二子像素20。所述折叠区AA-3位于所述第一显示区AA-1和第二显示区AA-2的对称轴上,并且分别连接所述第一显示区AA-1和第二显示区AA-2。
参见图3,本实施例中,所述折叠区AA-3发生形变,使所述第二显示区AA-2沿所述折叠区AA-3覆盖所述第一显示区AA-1,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能够在所述第一显示区AA-1和第二显示区AA-2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,所述第一显示区AA-1为上发光结构或双面发光结构,所述第二显示区AA-2为双面发光结构。重叠设置构成组合式显示屏之后,所述第二显示区AA-2为上发光结构。所述第一显示区AA-1的阳极为反射电极,阴极为透明电极。所述第二显示区AA-2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。
如图2和图3所示,在本实施例中,所述显示面板还包括非显示区AA-4,所述非显示区AA-4位于所述第一显示区AA-1或第二显示区AA-2的一条侧边上,与所述折叠区AA-3平行设置。所述非显示区AA-4设置有覆膜芯片和金属走线,用于控制所述第一显示区AA-1和第二显示区AA-2的显示。
在本实施例中,所述折叠区AA-3为可弯折的柔性薄膜或铰链结构,控制所述折叠区AA-3的形状可以实现所述折叠式显示屏的展开与折叠。所述折叠区AA-3上设置有覆膜芯片或柔性电路板,用于实现所述第一显示区AA-1和第二显示区AA-2的电连接,使所述第一显示区AA-1和第二显示区AA-2的控制信号相同,具体的,使所述第一像素单元P1和与其对应的第二像素单元P2接收的显示信息相同。
如图4和图5所示,图4为本申请的另一个具体实施例中的折叠式显示面板处于展开状态时的结构示意图,图5为图4中的折叠式显示面板处于折叠状态时的结构示意图。
在本申请的另一个实施例中,参见图4,所述显示面板还包括非显示区AA-4,所述非显示区AA-4位于所述第一显示区AA-1和第二显示区AA-2的一条侧边上,与所述折叠区AA-3垂直设置。所述非显示区AA-4设置有覆膜芯片和金属走线,用于控制所述第一显示区AA-1和第二显示区AA-2的显示。所述第一显示区AA-1和第二显示区AA-2的控制信号相同,具体的,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。
在本实施例中,所述非显示区AA-4直接与所述第一显示区AA-1和第二显示区AA-2电连接。本实施例中,不需要通过在所述折叠区AA-3上设置覆膜芯片或柔性电路板即可实现所述第一显示区AA-1和第二显示区AA-2的电连接。因此,相比于前一个实施例,所述折叠区AA-3的制作难度大大降低,制作成本也随之下降。
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显示区AA-1和第二显示区AA-22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显示区AA-2,分散所述第二显示区AA-2施加到第一显示区AA-1上的压力,避免第一显示区AA-1因为受力不均产生裂纹。另一方面也能够保证所述第一显示区AA-1和第二显示区AA-2之间的距离保持恒定,避免由于所述第一显示区AA-1和第二显示区AA-2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。
本申请提供的折叠式显示面板包括对应设置的第一显示区和第二显示区。所述第一显示区包括多个第一像素单元,所述第二显示区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。折叠后,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。
