Description

一种柔性OLED显示组件 技术领域
本发明涉及一种显示组件，尤其是，其中的一种柔性OLED显示组件。
 背景技术
已知，随着科学技术的不断进步，成像显示技术也相应的获得了极大的进步。从最初的CRT显示器开始，显示器技术开始了飞速的向前发展，不仅是在显示器本身的体积、重量上，而且在显示原理上也有了很大的不同。以目前的情况来讲，液晶显示器（Liquid Crystal Display，LCD）已经逐步取代CRT显示器。
进一步的，LCD显示器的显示器件通常是由一片薄膜晶体管阵列基板（Thin Film Transistor Array Substrate，TFT Array Substrate）与一片彩色滤光片（Color Filter，CF）基板贴合而成，且在TFT基板与CF基板之间灌入液晶，通过通电与否来控制液晶分子改变方向，将背光模组的光线折射出来产生画面。
虽然LCD显示器具有重量轻、显示效果好等优点，但其还是有一些缺陷，例如，不能折叠。对此，业界开发出了可折叠的有机发光二极管显示器件（Organic Light Emitting Diode，OLED）。
进一步的，由于OLED具有自发光、驱动电压低、发光效率高、响应时间短、清晰度与对比度高、近180°视角、使用温度范围宽，可实现柔性显示与大面积全色显示等诸多优点，被业界公认为是最有发展潜力的显示器件。
而柔性OLED的显示面板，其动态弯折主要是依赖背板（Plate）进行支持和实现弯折的。因此，在考虑实现柔性OLED显示面板动态弯折的结构设计方案时，除了需考虑该结构要具有良好的弯折反复性外，还需要考虑对弯折区域的OLED显示面板进行避让，避免应力造成损伤。
因此，确有必要开发一种新型的柔性OLED显示组件，来克服现有技术中的缺陷。

图1是本发明涉及的一个实施方式提供的一种柔性OLED显示组件的结构示意图；
图2是图1所示的一种柔性OLED显示组件，其弯折状态下的结构示意图。
 本发明的最佳实施方式
以下将结合附图和实施例，对本发明涉及的一种柔性OLED显示组件的技术方案作进一步的详细描述。
请参阅图1所示，本发明的一个实施方式提供了一种柔性OLED显示组件，包括OLED 面板20。其中所述OLED面板20上设置有第一折叠区，所述第一折叠区能沿其预定的一折叠线弯折。
而在不同实施方式中，所述OLED 面板20上设置的折叠区的数量可以是多个，例如，第一折叠区、第二折叠区、第三折叠区等等，每一折叠区都会设置有一预设折叠线用于所述折叠区沿线进行弯折。其中所述折叠区的具体设置数量可随需要而定，并无限定。而且，每个折叠区下都会设置两个支撑用背板，并沿其折叠线两侧设置。以下则以其中设置的第一折叠区为例进行举例性说明。
所述OLED面板20下设置有第一背10板和第二背板11，其中所述第一背板10和第二背板11分别沿所述第一折叠区的折叠线两侧分布。其中所述第一背板10的一端向外延伸出有第一支架12，所述第二背板11的一端延伸出有第二支架13，所述第一支架12与所述第二支架13的侧部相互抵接，所述OLED 面板20是设置在所述第一背板10、第一支架12、第二支架13和第二背板11的承载面上。
其中所述第一支架12和第二支架13相抵接侧部之间的形状设置为无间隙配合形状。例如，如图中所示，所述第一支架12和第二支架13相抵接的侧部之间是直线形状这种无间隙的配合形状，相应的，两者侧部形状之间的接触线则是与所述第一折叠区的预设折叠线上下竖直平行对应。
但在其他实施方式中，两者相抵接侧部之间的无间隙配合形状，也可以是其他类型的。例如，曲线形状、锯齿形状、凹凸形状等等，以上这些配合形状仅为举例性说明，具体也可以是其他已知的各种配合、咬接形状。而且，上述这些无间隙配合形状之间也可以是组合使用的，例如，一段是曲线配合形状，一段是锯齿配合形状等等，具体可随需要而定，并无限定。
对于所述第一支架12和第二支架13相抵接侧部之间采用非直线型的配合形状，例如，曲线形状、锯齿形状，凹凸形状等等，也可以有效的防止两者之间的相互错位移动，有利于两者间相互定位的稳定。对于这种支架侧部非直线型的无间隙配合形状，所述折叠区的折叠线则是与这种配合形状配接后的中轴线上下竖直平行对应。
进一步的，其中所述第一支架12与所述第二支架13相抵接端部的上顶角122、132为圆弧形，如此使得两者端部相接的所述承载面间存有一个上缺口14。同样的设计也出现在所述第一支架12与所述第二支架13相抵接端部的下顶角124、134处，其也为圆弧形，如此使得两者端部相接的底面间也存有一个下缺口15。

进一步的，在一个实施方式中，其中所述伸缩连接件16包括由弹性材料构成的弹性连接件，当其受力时，其可拉伸变长。其中所述弹性材料可以是业界已知的各种合适的弹性材料或是轻质弹簧，只要其拉伸后产生的回弹力不会影响到所述OLED面板20的弯折即可。具体选择，可结合所述第一支架12和第二支架13的长度，并通过具体实验来进行确定。
进一步的，在又一个实施方式中，其中所述伸缩连接件20包括链状拉伸结构，如图1中所示，所述链状拉伸结构在受力时能拉伸变长，并能在拉伸状态下受力缩回到原始正常状态。其中所述链状拉伸结构处于拉伸状态时，其可以是保持其长度状态而不产生任何回弹力，或者其也可以是会产生一定的回弹力，但不会影响到所述OLED面板20的弯折。
其中所述伸缩连接件16与所述第一支架12和第二支架13之间设置有间隔空间162。所述间隔空间162的设置可以避免所述伸缩连接件16与所述支架在OLED面板20弯折时，可能存在的意外干涉。
而在其他不同实施方式中，其中所述伸缩连接件16也可以是与所述第一支架12和第二支架13的底部相接，只要两者在所述OLED面板20弯折时，互不干涉即可。具体可随需要而定，并不限定。
进一步的，在设置有所述间隔空间162的实施方式中，其中所述间隔空间162内还设置有一支撑板17，其连接设置在所述第一支架12或是第二支架13的底部上，并能同时对所述第一支架12和第二支架13进行支撑。对于所述支撑板17的设置方式，其可以是各种业界已知的底部连接方式，例如，螺钉172连接方式，但不限于。
当然，在其他实施方式中，所述支撑板也可以有多种的实施方式。例如，所述支撑板可以是包括第一支撑板和第二支撑板，分别设置在所述第一支架和第二支架的底部上并相接侧部抵接。
其中所述第一支撑板和第二支撑板相抵接的侧部之间为无间隙配合形状设置。其中的所述无间隙配合形状可以包括已知的各种配合、咬接形状，例如，直线形状，曲线形状，锯齿形状，凹凸形状，但不限于。而且，上述这些无间隙配合形状之间也可以是组合使用的，例如，一段是曲线配合形状、一段是锯齿配合形状等等，具体可随需要而定，并无限定。
其中所述两支撑板相接两侧部的形状设置还可参考所述两支架相接两侧部的形状设置，其结构类似，为避免不必要的重复，此处不再过多描述。
请参阅图2所示，当对所述OLED面板20进行弯折时，其中所述第二背板11受力向上弯折，所述第二支架13会抵靠所述第一支架12进行转动，进而拉伸所述拉伸连接件20，使其由正常原始状态变为拉伸状态。
其中，由于所述第一支架12和第二支架13相抵接端部的上顶角122、132为圆弧形设计，这就使得所述OLED面板20在弯折时便于滑动，且两个相抵接的圆弧形顶角122、132设计间产生的上缺口14在所述OLED面板20弯折时，也使其有了一定避让空间。
而所述支撑板17的设置，则是为了确保所述OLED面板20弯折后的所述两个支架12、13能在一个水平面，且不会出现过弯折现象；而且，所述支撑板17还能起到向外抵靠所述伸缩连接件16的功能，防止所述伸缩连接件16在拉伸后向内侧凹陷。
本发明涉及的一种柔性OLED显示组件，其通过设置一个伸缩连接件，实现了很好的弯折反复性，且能对弯折区域的OLED面板进行避让，避免弯折应力对其造成损伤。
本发明的技术范围不仅仅局限于上述说明中的内容，本领域技术人员可以在不脱离本发明技术思想的前提下，对上述实施例进行多种变形和修改，而这些变形和修改均应当属于本发明的范围内。
