Description

一种显示装置、柔性基板及其制作方法
技术领域
本发明涉及柔性显示技术领域，特别涉及一种显示装置、柔性基板及其制作方法。
背景技术
随着电子信息的飞速发展以及消费者越来越高品质的需求，显示器的品质和显示模式起到了十分重要的作用。消费者已经不满足单纯的视觉感知，还要求显示器更轻薄、便携化、个性化等。从厚重的CRT到薄型化的LCD便是一个质的飞跃，如今LCD在一些显示品质方面的突破如高分辨率、窄边框、低功耗也有了很大的进展。近些年来，发展迅速的3D、touch等功能受到了广大消费者的欢迎。但是LCD由于液晶材料固有特性导致响应速度慢、对比度低、视角小的缺陷还是难以突破。下一代显示OLED（Organic Light Emitting Device）技术的出现引起了广泛的关注，它具有优秀的显示品质，无视角和对比度限制，轻薄型（～0.2mm），自主发光，成为各大面板厂商争相开发的具有竞争力的技术。
传统的显示都是平板显示，不可以随意弯曲。未来显示的趋势是希望在柔性体上实现展示大量的信息即柔性显示。官方定义为显示屏和模组在基板包装、生产、存储、使用、操作、工序衔接、搬运、运输等任何一个步骤可以实现机械弯曲功能的显示器件（引自IECTC110WG8）。实现柔性显示的关键技术可以分为几个方面：显示技术、基板技术、阵列技术和封装技术。目前可以实现柔性显示的显示技术有LCD、OLED、EPD（电子纸显示）、PDLC（聚合物分散液晶）、ChLC(胆甾相液晶)模式。基板主要有超薄玻璃、金属箔片、塑料这三种方式。阵列技术除传统的非晶硅技术，近些年逐步发展的低温多晶硅（LTPS）、氧化物（oxide）、有机薄膜晶体管（OTFT）技术。OLED器件对水汽、氧非常敏感，很容易发生衰减，柔性OLED必须进行封装，主要有玻璃盖板式和薄膜封装（TFE）。
超薄玻璃基板的水汽、氧阻隔性能好，透明性好，但是它对裂纹缺陷很敏感，抗冲击性、弯折性很差，不易实现卷对卷（roll to roll）的工艺，开发超薄可挠曲的玻璃很难实现。金属箔片基板具有阻隔水氧的功能，耐高温低成本，本身具有延展性，易于实现卷对卷工艺，但是箔片表面粗糙(Ra=0.6um)，即使经过抛光处理后，仍然需要镀上平坦化层，这增加了器件的厚度。塑料基板柔韧性更好、质量更轻、更耐冲击，但是塑料基板不耐高温，必须在很低的温度下完成TFT制程，这会增加薄膜中的缺陷，但是在高温下塑料的变形量很大，高于玻璃化转变温度，塑料变形量严重增加而且塑料基板与薄膜的晶格匹配不如玻璃，薄膜易脱落。
发明内容
（一）要解决的技术问题
本发明解决如下技术问题，提供一种不易变形，同时兼顾强度和柔软度的显示装置、柔性面板及其制作方法。
（二）技术方案

优选地，所述纤维按照（0°，90°）或者(45°,-45°)正交方式交错分布。
优选地，所述纤维包括玻璃纤维和碳纤维。
优选地，所述纤维为圆束状。
另一方面，本发明还提供一种柔性基板的方法，包括：
步骤S1，在衬底上覆盖一层由树脂类材料制成的柔性层；
步骤S2，对柔性层进行预固化处理；
步骤S3，覆盖一层纤维铺层，所述纤维铺层由纤维交错分布形成；
步骤S4，在完成步骤S3的基础上继续覆盖一层由树脂类材料制成的柔性层；

（三）有益效果
本发明提供一种显示装置、柔性基板及其制作方法，采用由柔性层和纤维铺层共同形成柔性基板，可有效防止柔性层发生高温变形，降低应力，最大程度地提高基板上薄膜的附着力，提高基板的弯曲和压缩强度。
附图说明
图1为本发明实施例柔性基板结构示意图；
图2为本发明实施例柔性基板中纤维其中一种正交方式分布示意图；
图3为本发明实施例柔性基板中纤维另外一种正交方式分布示意图；
图4为本发明实施例柔性基板制作方法流程图。
具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。
如图1所示，本发明实施例提供一种柔性基板，包括：
衬底1，所述衬底上设有若干层柔性层2，所述相邻两层柔性层2之间设有纤维铺层3。其中，柔性层2由树脂类材料制成。
本实施例中在两层柔性层之间加设纤维铺层3，可有效防止柔性层发生高温变形，降低应力，最大程度地提高基板上薄膜的附着力，提高基板的弯曲和压缩强度。
具体的，所述树脂类材料优选采用树脂塑料。其中，树脂塑料优选例如可以为聚酰亚胺、聚对萘二甲酸乙二醇酯或聚对苯二甲酸乙二醇酯，该柔性层的厚度在几十微米以下。
参考图2和图3，由于柔性显示器件承受的机械强度主要为弯曲和压缩强度，因此，设置纤维铺层中的纤维按照（0°，90°）或者(45°,-45°)正交方式交错分布，这样，与相比其他铺层方式相比，可最大程度得提高不同方向的弯曲和压缩性能。
其中，纤维按照（0°，90°）正交方式交错分布，具体指的是，一部分纤维按照平行于X坐标轴方向进行分布，另一部分纤维按照平行于Y坐标轴方向进行分布，使得两部分纤维呈90°正交方式进行交错分布。
需要说明的是，纤维按照(45°,-45°)正交方式交错分布，具体指的是，一部分纤维按照与X坐标轴呈45°夹角方向进行分布，另一部分纤维按照与Y坐标轴呈45°夹角方向进行分布，使得两部分纤维呈90°正交方式进行交错分布。
其中，纤维优选例如可以为玻璃纤维、碳纤维。
优选地，所述纤维为圆束状。纤维结构为圆束状，与树脂接触的比表面积相比于其他形状要大，故纤维与树脂的粘结强度较高，树脂固化后，在纤维方向上一定程度的限制了树脂的高温变形，缩小高温变形量。进而提高在基板上面生长的薄膜的粘附力，减少薄膜脱落的可能性。
本发明提供一种柔性基板，采用由柔性层和纤维铺层共同形成柔性基板，可有效防止柔性层发生高温变形，降低应力，最大程度地提高基板上薄膜的附着力，提高基板的弯曲和压缩强度。
如图4所示，本发明还提供一种制作上述柔性基板的方法，包括：
步骤S1，在衬底上覆盖一层由树脂类材料制成的柔性层。
其中，树脂类材料优选树脂塑料，该树脂塑料的厚度在几十微米以下，该树脂塑料优选为聚酰亚胺（PI）、聚对萘二甲酸乙二醇酯(PEN)、聚对苯二甲酸乙二醇酯(PET)。
步骤S2，对柔性层进行预固化处理，使其在衬底上具有一定的形态和强度。
其中，预固化的固化时间为80-150min；固化温度为80-200℃。
步骤S3，覆盖一层纤维铺层，所述纤维铺层由纤维交错分布形成。
具体的，设置纤维铺层中的纤维按照（0°，90°）或者(45°,-45°)正交方式交错分布，这样，与相比其他铺层方式相比，可最大程度得提高不同方向的弯曲和压缩性能。
在两层柔性层之间加设纤维铺层3，可有效防止柔性层发生高温变形，降低应力，最大程度地提高基板上薄膜的附着力，提高基板的弯曲和压缩强度。
步骤S4，在完成步骤S3的基础上继续覆盖一层由树脂类材料制成的柔性层。
步骤S5，重复步骤S3～S4若干次。
本步骤中，通常重复S3～S4操作2～4次，以提高柔性基板的强度。重复S3～S4操作的次数可以根据实际需求而定。
步骤S6、将完成步骤5的柔性基板抽真空，并进行固化保温处理。其中，固化时间为60min～120min。
柔性基板抽真空，并进行固化保温处理，可以使其排出挥发组分，使多层复合的材料固化压实，排掉树脂内部孔洞，提高机械性能。
本发明提供一种柔性基板的制作方法，采用由柔性层和纤维铺层共同形成柔性基板，可有效防止柔性层发生高温变形，降低应力，最大程度地提高基板上薄膜的附着力，提高基板的弯曲和压缩强度。
另外，本发明还提供一种显示装置，包括上述的柔性基板，实现柔性显示。该显示装置可以为：液晶面板、电子纸、OLED面板、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。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和变型，这些改进和变型也应视为本发明的保护范围。
