Description

显示面板的柔性盖板 技术领域
本发明涉及柔性显示技术领域，尤其涉及一种显示面板的柔性盖板。
背景技术
传统的显示盖板材料多为刚性的玻璃或树脂(如PMMA，即聚甲基丙烯酸酯)与功能层复合而成。玻璃显示盖板不可弯折，不符合可折叠显示器件的发展趋势，而树脂虽然可弯折，但是其阻水性不佳，水汽极易穿透盖板进入器件内，最终导致OLED(Organic Light Emitting Display，即有机发光显示器)产生黑点而失效。
发明内容
鉴于现有技术存在的不足，本发明提供了一种显示面板的柔性盖板，可以兼顾柔性弯折性能和阻水性能，适用于各种柔性显示装置。

作为其中一种实施方式，位于柔性盖板最外层的所述层叠单元的所述复合层表面还覆盖有一层所述有机层。
作为其中一种实施方式，所述的显示面板的柔性盖板还包括覆盖于柔性盖板出光面的透明的硬化层。
作为其中一种实施方式，多层所述层叠单元层叠设置，且至少两个所述复合层中的所述第一部分的宽度不同。
作为其中一种实施方式，沿所述第一部分的弯折方向，相应的所述复合层 上的所述第一部分的宽度逐渐增大。
作为其中一种实施方式，所述第一部分外表面为曲面，越靠近所述第一部分的曲率中心，相应的所述复合层上的所述第一部分的宽度越小。
或者，位于中部的所述复合层上的所述第一部分的宽度最小，且越远离中部的所述复合层，各所述复合层中的所述第一部分的宽度越大。
作为其中一种实施方式，所述第一部分包括多个间隔设置的通孔，每个所述通孔内填充有与所述第二部分相同的材料。
作为其中一种实施方式，所述有机层和所述第一部分均为有机材料，所述第二部分为无机材料。
本发明的柔性盖板由于具有层叠设置的复合层和有机层，复合层具有可弯折的第一部分，第一部分两端的第二部分可相对于中部的第一部分进行弯折，因此，使得整个柔性盖板具有良好的弯折性能，同时，也保证了柔性盖板的阻水性能。

为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明实施例的柔性盖板可以用于各种柔性显示面板，参阅图1所示，为本实施例的柔性盖板1应用在一种OLED面板中的情形，OLED面板P包括底层的柔性的PI(Polyimide，即聚酰亚胺)基板2、制作在PI基板2上的LTPS(Low Temperature Poly-silicon，即低温多晶硅)层3、设于LTPS层3上方的有机发光层4、封装在有机发光层4表面的封装层5、偏光片6以及柔性的触摸屏7，柔性盖板1覆盖在触摸屏7表面，在有的实施方式中，触摸屏7可以省去，该柔性盖板1作为OLED面板的盖板层，具有保护面板、防水防尘等功能，同时还能根据需要进行弯折，实现不同的显示或外观效果。
具体地，该柔性盖板包括至少一层层叠单元，每层层叠单元均包括一层复合层和位于复合层底部的可弯折的有机层。每层复合层包括至少一个第一部分和位于第一部分两端的第二部分。有机层和复合层中部的第一部分柔韧性能较好，可很方便地进行弯折，而复合层的第一部分两端的第二部分硬度大于第一部分，不易弯折，具有较强的阻水能力，在第一部分弯折后，两端的第二部分可以保持较好的平整性。其中，复合层和有机层可以均为多层，且有机层与复合层沿柔性盖板的厚度方向上交替地层叠设置，这样既能保证良好的弯折性能，又能保证较好的阻水性能和非弯折部位的平整性，提升柔性盖板的整体性能。
实施例1
结合图2所示，本实施例的柔性盖板1包括至少一层层叠单元1a，每层层叠单元1a均包括一层复合层10和设于复合层10底部的可弯折的有机层20，以及覆盖于柔性盖板1最上方(即其出光面)的透明的硬化层30，该硬化层可以是透明的无机材料，如包括Siloxane(硅氧烷)的无机材料，可以在异常宽的温度范围(-100℃～250C)内还能保持其物理特性，形成具有耐高温、耐氧化，稳定性好，且兼具良好的斥水性及介电性能的保护材料。每层复合层10组成大致相同，均包括中部的第一部分11和位于第一部分11两端的第二部分12。中部的第一部分11可随意进行弯折，而两端的第二部分12硬度大于第一部分11，不易弯折，具有较强的阻水能力，有机层20可以与第一部分11材料相同。
按区域分，柔性盖板1可分为可弯折区B和位于可弯折区B两端的不易弯折的非弯折区F，为保证柔性盖板的可弯折区B具有更好的柔韧性能、非弯折区F具有更好的刚性，复合层10和有机层20均为多层，且有机层20与复合层10沿柔性盖板1的厚度方向上交替地层叠设置，各第一部分11的投影的最大宽度即为可弯折区B的宽度。
这里，有机层20和第一部分11均为有机材料，第二部分12为无机材料。作为其中一种实施方式，有机层20和第一部分11为透明的树脂，有机层20或第一部分11可以选自无色的聚酰亚胺、聚氨酯(PU)、聚对苯二甲酸乙二醇酯(PET)或聚萘二甲酸乙二醇酯(PEN)。第二部分12为透明的陶瓷材料，可选自SiO 2、SiN、SiON或Al 2O 3。在制作时，有机层20和/或第一部分11可采用喷墨打印法在衬底上沉积形成，第二部分12可采用等离子体增强化学气相沉积法(PECVD)或原子层沉积法(ALD)在衬底上沉积形成。
层叠单元1a的数量不作限制，可以根据实际需要自由选择。本实施例中，多层层叠单元1a层叠设置在触摸屏7表面，位于柔性盖板最外层的层叠单元1a的复合层10表面还覆盖有一层有机层20，硬化层30覆盖在最外层有机层20表面。即复合层10、有机层20的具体层数并不做限定，二者只需交替排列即可，柔性盖板1中与硬化层30的内表面贴合的是有机层20，位于内侧、用于与OLED面板P贴合的也是有机层20，可以对中间的复合层10起到保护效果。结合图3所示，为本实施例的柔性盖板1弯折后的效果图，柔性盖板1朝向OLED面板P弯曲形成内凹的显示面，即柔性盖板1两端翘起、中间凹陷，位于出光面所在侧的硬化层30为内凹的曲面结构，位于硬化层30中间区域为与各复合层10的第一部分11正对的弯折部，硬化层30的边缘区域为与弯折部相连的平整部。
由于此种弯曲的柔性盖板1中，越靠近OLED面板P，柔性盖板1所受到的拉应力越大，尤其是柔性盖板1的中间区域，因此，本实施例中，各层层叠单元1a内的复合层10之间不同的是，至少两个复合层10中的第一部分11的宽度不同，进一步地，越靠近硬化层30，各层复合层10中的第一部分11的宽度越小，即越靠近OLED面板P，各层复合层10中的第一部分11的宽度越大，可以减轻弯折时可弯折区B所受的应力，避免各层复合层10在靠近可弯折区B处的第二部分12破裂，从而保证柔性盖板1在弯折过程中不会出现折损，兼具优良的柔韧性和阻水性。
在其他实施方式中，硬化层30的弯折部在弯折后也可以设计成平滑的弧面，其弧面凹陷方向与其弯折方向一致，越靠近弯折部的曲率中心，相应的复合层10上的第一部分11的宽度越小；由于硬化层30与其相邻的有机层20之间、各层叠单元1a之间均始终保持贴合状态，第一部分11与硬化层30的弯折部的形状一致。
在制作本实施例的柔性盖板1时，首先提供一衬底，然后在衬底纵向上依次交替地沉积有机层20和复合层10，最后，在最顶层的有机层20表面覆盖硬化层30，并剥离最底层的衬底。其中，有机层20采用喷墨打印法等沉积有机材料形成，复合层10为在有机层20表面对应可弯折区B的部位采用喷墨打印法等沉积有机材料形成第一部分11，并在有机层20表面对应可弯折区B外的部位采用PECVD或ALD等沉积无机材料形成第二部分12，当在衬底上沉积一层最底层的有机层20后，先在该最底层的有机层20表面沉积一层具有镂空图案的第二部分12，然后在该第二部分12的镂空图案内填充有机材料形成第一部分11，再在第二部分12和第一部分11表面沉积一层有机层20，如此反复沉积，最后在最表层沉积一层有机层20，并覆盖硬化层30即可。当第一部分11与有机层20采用相同的材料时，第一部分11与有机层20的制作可一次成型，即具有镂空图案的第二部分12形成后，直接在第二部分12表面沉积一层有机材料，使其同时填充第二部分12的镂空区域，并在第二部分12表面形成一层有机层20，可以简化制作工艺，层间的结合强度更可靠。
上下设置的第一部分11层叠设置，且越往上的复合层10中，第一部分11的宽度越来越窄、第二部分12的宽度越来越宽。最底层的衬底剥离后，即可在可弯折区B施加朝下的弯折力，使可弯折区B发生弯曲，从而形成两端翘起，中间凹陷的柔性盖板1。
实施例2
结合图4和图5所示，与实施例1不同的是，本实施例的柔性盖板1背向OLED面板P拱起形成外凸的显示面，位于出光面所在侧的硬化层30为外凸的曲面结构，位于硬化层30中间区域为与各复合层10的第一部分11正对的弯折部，硬化层30的边缘区域为与弯折部相连的平整部。
由于此种弯曲的柔性盖板1中，越远离OLED面板P，柔性盖板1所受到的拉应力越大，尤其是柔性盖板1的中间区域，因此，本实施例中，越靠近硬化层30，各层复合层10中的第一部分11的宽度越大，可以减轻弯折时可弯折区B所受的应力，避免各层复合层10在靠近可弯折区B处的第二部分12破裂。
在其他实施方式中，弯折后的硬化层30的弯折部也可以设计成平滑的弧面，其弧面凸起方向与其弯折方向一致，越靠近弯折部的曲率中心，相应的复合层10上的第一部分11的宽度越小。
与实施例1不同的是，本实施例的柔性盖板1中，越往上的复合层10，其第一部分11的宽度越来越宽、第二部分12的宽度越来越窄。最底层的衬底剥离后，在可弯折区B施加的弯折力朝上，使可弯折区B发生弯曲，从而形成中间拱起，两端下垂的柔性盖板1。
实施例3
如图6～8所示，与以上实施例不同的是，本实施例的柔性盖板1可以弯折多次，包括多个非弯折区F和位于每两个非弯折区F之间的可弯折区B，与之相应地，每层复合层10均包括多个第二部分12和连接于每两个第二部分12之间的第一部分11，硬化层30包括多个与各复合层10的第一部分11正对的弯折部。
本实施例示出的是柔性盖板1具有两个可弯折区B的情形，其两个可弯折区B的弯折方向相反，以方便显示装置进行适当折叠和展开。相应地，硬化层30具有两个分别与各复合层10的第一部分11正对的两个弯折部，柔性盖板1的其中一个可弯折区B如实施例1的弯折方式，硬化层30在该处的弯折部为内凹的曲面结构，在该可弯折区B，越靠近OLED面板P，各层复合层10中的第一部分11的宽度越大，可以减轻弯折时该可弯折区B所受的应力；另一个可弯折区B如实施例2的弯折方式，硬化层30在该处的弯折部为外凸的曲面结构，在该可弯折区B，越靠近硬化层30，各层复合层10中的第一部分11的宽度越大，可以减轻弯折时可弯折区B所受的应力。
可以理解的是，本实施例并不对柔性盖板的弯折次数进行限制，在实际应用中可以根据需要设计柔性盖板的弯折次数。
在制作本实施例的柔性盖板1时，首先提供一衬底，然后在衬底纵向上依次交替地沉积有机层20和复合层10，最后，在最顶层的有机层20表面覆盖硬化层30，并剥离最底层的衬底。其中，有机层20采用喷墨打印法等沉积有机材料形成，复合层10为在有机层20表面对应各个可弯折区B的部位采用喷墨打印法等沉积有机材料形成第一部分11，并在有机层20表面对应其余部位采用PECVD或ALD等沉积无机材料形成第二部分12，上下设置的第一部分11层叠设置，且在其中一个可弯折区B，越往上的复合层10中，第一部分11的宽度越来越窄，在与该可弯折区B相邻的可弯折区B，越往上的复合层10中，第一部分11的宽度越来越宽，即，在纵向上，各复合层10中的第一部分11的宽度变化趋势相反。最底层的衬底剥离后，即可在各可弯折区B朝第一部分11的宽度变大的方向施加弯折力，使各可弯折区B发生相应方向的弯曲动作，从而形成多次弯折的柔性盖板1。
实施例4
如图9所示，本实施例的每个第一部分11均包括多个在其宽度方向上间隔设置的通孔110，每个通孔110内填充有与第二部分12相同的材料，当柔性盖板在可弯折区B进行弯折时，第一部分11相应地进行弯折，由于第一部分11内间隔地填充有与第二部分12相同的材料，可以减小可弯折区B与非弯折区F的折射率差异，从而降低可弯折区B与非弯折区F的显示效果的差异性。
在制作本实施例的柔性盖板1时，与实施例4不同的仅仅是各复合层10的制程，在制作各复合层10时，可首先在有机层20表面沉积具有多个通孔110的图案化的无机材料层，然后在该无机材料层表面沉积一层有机材料层，该有机材料层完全覆盖底层的无机材料层并填充于无机材料层的通孔110中，如此即可实现复合层10的第一部分11与上层的有机层20一次成型，然后在复合层10表面再沉积下一层有机层20。
实施例5
如图10和图11所示，与实施例1和实施例2不同的是，本实施例的柔性盖板1中，位于中部的复合层10的第一部分11的宽度最小，且越远离中部的复合层10，各复合层10中的第一部分11的宽度越来越大，各复合层10、有机层20的端面平齐，且复合层10中部的第一部分11关于复合层10的对称中心 对称设置。每层复合层10中部的第一部分11均可进行弯折，第二部分12难以弯折，位于最上层和最下层的复合层10的第一部分11具有最大的宽度，各第一部分11的投影的最大宽度即为可弯折区B的宽度，位于可弯折区B外的均为非弯折区F。
如图11所示，设计时，结合复合层10、有机层20的厚度及弹性模量，中性轴被设置在中心的复合层10。考虑到弯折时，离中性轴越远的层，其应变会越大。而根据应力公式σ＝Eε，其中，σ表示应力，E代表弹性模量，ε表示应变，可知，应变相同时，材料的弹性模量越大，材料所受到的应力也越大，材料损坏的风险也相应越高，而无机的复合层10的弹性模量大于有机的有机层20，故在远离中性轴的大应变区域，需要使用弹性模量更小的有机层更容易降低盖板折损的风险。因此，中性轴所在的复合层10的第一部分11的宽度越小，越远离中性轴的复合层10的第一部分11的宽度越大，这样越有利于盖板的弯折。
本实施例的柔性盖板1的可弯折区B可以朝靠近OLED面板的方向弯折，也可以朝背离OLED面板的方向弯折，弯折后的柔性盖板1仍能保持良好的柔韧性，此种可弯折区B也可以与实施例1或实施例2的弯折方式结合而同时存在于同一个柔性盖板1中。
本发明的柔性盖板由于具有层叠设置的复合层和有机层，复合层具有可弯折的第一部分，第一部分两端的第二部分可相对于中部的第一部分进行弯折，有机层与复合层沿柔性盖板的厚度方向上交替地层叠设置，使得整个柔性盖板具有良好的弯折性能，同时，也保证了柔性盖板的阻水性能。
以上所述仅是本申请的具体实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。
