具体实施方式
现在将参考附图更全面地描述示例实施方式。然而,示例实施方式能够以多种形式实施,且不应被理解为限于在此阐述的实施方式;相反,提供这些实施方式使得本公开将全面和完整,并将示例实施方式的构思全面地传达给本领域的技术人员。图中相同的附图标记表示相同或类似的结构,因而将省略它们的详细描述。
本示例实施方式首先提供了一种柔性显示组件,参照图1所示的本公开柔性显示组件一示例实施方式的结构示意图;该柔性显示组件可以包括支撑件1、柔性显示面板、覆覆盖层组3以及粘接部4;柔性显示面板2设于所述支撑件1的一侧,所述柔性显示面板2的宽度小于支撑件1的宽度,使所述支撑件1的第一端突出于所述柔性显示面板2;覆盖层组3设于所述柔性显示面板2的远离所述支撑件1的一侧,所述柔性显示面板2的宽度小于所述覆盖层组3的宽度,使所述覆盖层组3的第一端突出于所述柔性显示面板2,使所述覆盖层组3、所述柔性显示面板2与所述支撑件1的第一端形成两侧突出中间凹陷的结构;粘接部4粘接于所述支撑件1的第一端与所述覆盖层组3的第一端之间。
在柔性显示组件进行折弯或卷曲时,位于外层的膜层受到的是拉力,位于内层的膜层受到的是压力,在该柔性显示组件卷曲或折弯然后展开后,由于覆盖层组3的特性在第一端还会保持一定的弯曲状态,在第一端覆盖层组3会带动柔性显示面板2使柔性显示面板2发生剥离现象,在第一端将位于柔性显示面板2两侧的覆盖层组3和支撑件1通过粘接部4粘接,在第一端将覆盖层组3受到的拉力转移至粘接部4,从而避免柔性显示面板2发生剥离现象,防止发生功能失效;在柔性显示组件进行折弯或卷曲时,覆盖层组3起始位置的应力最大,将覆盖层组3的第一端与支撑件1粘接相较于将覆盖层组3的第一端与柔性显示面板2粘接,应力集中在剥离力较大的粘接部4上,避免了小剥离力的柔性显示面板2的膜层发生剥离现象,而且避免覆盖层组3表面破损;而且粘接部4具有一定的弹性和延展性能够吸收拉力和压力,从而进一步减小卷曲应力,防止发生功能失效。
需要说明的是,所提及的正投影都是在柔性显示组件处于完全展开状态时。长度指的是与卷轴8的轴向一致的方向的尺寸,宽度指的是指与卷轴8的轴向垂直且与柔性显示面板的显示面平行的方向的尺寸。
在本示例实施方式中,支撑件1可以为金属支撑件。参照图2所示,支撑件1也可以包括金属支撑板11,在金属支撑板11上设置有多个条形通孔12,多个条形通孔12可以阵列排布,也可以非阵列排布。可以在条形通孔12内填充硅胶、橡胶等等。条形通孔 12的形状可以是腰圆孔、椭圆形、长方形等等,当然,也可以设置为圆形通孔、方形通孔等等。也可以不在条形通孔12内填充硅胶。金属支撑件可以采用整面金属支撑板11,金属支撑板11的厚度可以大于等于30微米且小于等于300微米。当然,在本公开的其他示例实施方式中,支撑件1也还可以采用整面胶体材质,例如硅胶、橡胶等等,胶体材质的厚度可以小于等于1毫米。当然,也可以采用设置有图案的胶体材质的平板,即在胶体材质的平板上设置通孔,胶体材质的平板的厚度可以小于等于2毫米。
在本示例实施方式中,在金属支撑板11的相对两侧均设置有隔垫层,分别为第一隔垫层61和第二隔垫层62。第一隔垫层61设于金属支撑板11与柔性显示面板2之间。第二隔垫层62设于金属支撑板11的远离柔性显示面板2的一侧。第一隔垫层61和第二隔垫层62的材质可以均是泡棉,还可以均是胶体材质,例如硅胶、橡胶等等。由于支撑件1为金属支撑件,其硬度较硬,而且金属支撑板11上设置有条形通孔12,在形成条形通孔12时不可避免会形成一些毛刺或凸起,在后续的柔性显示组件折弯或卷曲的过程中会对与金属支撑板11接触的膜层产生摩擦而导致损伤。设置第一隔垫层61可以避免金属支撑板11对柔性显示面板2的损伤。第二隔垫层62可以避免该柔性显示组件卷曲后,金属支撑板11与覆盖层组3接触,从而避免金属支撑板11对覆盖层组3的损伤。当然,在本公开的其他示例实施方式中,可以不设置第一隔垫层61和第二隔垫层62,例如在支撑件1为胶体材质的情况下。
在本示例实施方式中,第一隔垫层61在金属支撑板11上的正投影与柔性显示面板2在金属支撑板11上的正投影重合,即第一隔垫层61的长度和宽度与柔性显示面板2的长度和宽度对应相等,使金属支撑板11的第一端突出于第一隔垫层61。粘接部4粘接于金属支撑板11与覆盖层组3之间。第二隔垫层62在支撑件1上的正投影位于支撑件1内,使支撑件1的第一端突出于第二隔垫层62。
另外,在本公开的另外一些示例实施方式中,第一隔垫层61的长度和宽度可以与金属支撑板11的长度和宽度对应相等,这种情况下粘接部4粘接于第一隔垫层61与覆盖层组3之间。第二隔垫层62在支撑件1上的正投影可以与支撑件1重合,即第二隔垫层62的长度和宽度可以与金属支撑板11的长度和宽度对应相等。
在本示例实施方式中,在第一隔垫层61的远离支撑件1的一侧设置有柔性显示面板2。柔性显示面板2的宽度小于支撑件1的宽度,使支撑件1的第一端可以突出于柔性显示面板2,该突出宽度可以大约为35mm,当然该突出宽度不限于上述说明可以根据需要设定可以更大也可以更小,支撑件1的与第一端相对的第二端可以与柔性显示面板2齐平。而在长度方向,柔性显示面板2的长度可以大于支撑件1的长度,当然,也可以是柔性显示面板2的长度小于或等于支撑件1的长度。
在本示例实施方式中,在柔性显示面板2的远离支撑件1的一侧设置有OCA(Optically Clear Adhesive)光学胶层,即OCA光学胶层7设于覆盖层组3与柔性显示面板2之间,OCA光学胶层7将覆盖层组3与柔性显示面板2粘接在一起。OCA光学胶层7是用于粘接覆盖层组3与柔性显示面板2的,因此,OCA光学胶层7在支撑件1上的正投影与柔性显示面板2在支撑件1上的正投影重合,即OCA光学胶层7的长度和宽度与柔性显示面板2的长度和宽度对应相等。
在本示例实施方式中,在OCA光学胶层7的远离支撑件1的一侧设置有覆盖层组3,覆盖层组3可以包括覆盖层31,柔性显示面板2在支撑件1上的正投影位于覆盖层31在支撑件1上的正投影内,即柔性显示面板2的宽度小于覆盖层31的宽度,使覆盖层31的第一端突出于柔性显示面板2,该突出宽度可以大约为35mm,当然该突出宽度不限于上述说明可以根据需要设定可以更大也可以更小,覆盖层31的第一端突出于柔性显示面板2的宽度与支撑件1的第一端可以突出于柔性显示面板2的宽度可以相同,也可以不同;只要能够满足粘接部4的粘接要求以及间隙5的宽度要求即可。覆盖层31的第一端与支撑件1的第一端相对设置,使覆盖层组3、柔性显示面板2与支撑件1的第一端形成两侧突出中间凹陷的结构,而且这种结构以及粘接部4只设置在柔性显示组件的第一端,在其他侧面没有如此设置。
在本示例实施方式中,在支撑件1的第一端与覆盖层31的第一端之间粘接有粘接部4,且粘接部4与柔性显示面板2之间设置有间隙5,使覆盖层组3与柔性显示面板2能够发生微量的自由错动,进一步释放卷曲应力,防止发生功能失效。间隙5的宽度大于等于0.1毫米且小于等于2毫米。粘接部4的厚度小于或等于支撑件1的靠近柔性显示面板2的一面与覆盖层31的靠近柔性显示面板2的一面之间的距离,粘接部4的宽度小于覆盖层31的第一端突出于柔性显示面板2的宽度和支撑件1的第一端突出于柔性显示面板2的宽度中的最小值。具体来说,粘接部4的宽度大约为34.5mm,当然,粘接部4宽度不限于上述说明可以根据需要设定可以更大也可以更小,只要粘接部4的宽度能够保证使粘接部4的粘接力大于覆盖层组3与柔性显示面板2之间的粘接力以及柔性显示面板2与支撑件1之间的粘接力。粘接部4的弹性模量与OCA光学胶层7的弹性模量近似,使覆盖层组3各部分的受力均衡,避免覆盖层组3受力不均,具体为:粘接部4的弹性模量大于等于OCA光学胶层7的弹性模量的10%且小于等于OCA光学胶层7的弹性模量的200%,优选为90%-110%。在覆盖层31上还设置有HC(Hard coating,表面硬化)膜层,覆盖层31上的应力的到释放后,还可以避免HC膜层产生裂纹。
参照图3所示的本公开柔性显示组件另一示例实施方式的结构示意图;该示例实施方式与图1中所示的示例实施方式的主要区别在于覆盖层组3的结构不同。
具体而言,在本示例实施方式中,覆盖层组3可以包括覆盖层31a和挡板32;覆盖层31a设于柔性显示面板2的远离支撑件1的一侧,覆盖层31a的宽度小于支撑件1的宽度,且柔性显示面板2在支撑件1上的正投影位于覆盖层31a在支撑件1上的正投影内,使覆盖层31a的第一端突出于柔性显示面板2;即覆盖层31a的宽度大于柔性显示面板2的宽度且小于支撑件1的宽度。本示例实施方式中的覆盖层31a的宽度小于图1中所示的示例实施方式中的覆盖层31的宽度。当然,在本公开的另外一些示例实施方式中,覆盖层31a的宽度可以等于柔性显示面板2的宽度,即覆盖层31a没有突出于柔性显示面板2。
挡板32设于覆盖层31a的远离支撑件1的一侧,挡板32的第一端粘接于粘接部4,挡板32的与第一端相对的第二端搭设于覆盖层31a的远离支撑件1的一侧,即挡板32在支撑件1上的正投影与覆盖层31a在支撑件1上的正投影部分重合。所谓搭设即挡板32与覆盖层31a可以接触也可以不接触,只是挡板32与覆盖层31a有部分重叠。在柔性显示组件折弯或卷曲时,使覆盖层31a受到的拉力或压力较小,而且由于挡板的搭设覆盖层31a可以较为自由的错动,避免覆盖层31a的翘起。挡板32可以设置为直板状。此时,粘接部4的厚度小于或等于支撑件1的靠近柔性显示面板2的一面与挡板32的靠近柔性显示面板2的一面之间的距离。
在本公开的其他示例实施方式中,参照图6所示;挡板32可以设置为圆弧形,挡板32的弯曲方向与柔性显示面板2的弯曲方向一致,在柔性显示装置中,挡板32可以沿卷轴8的周向弯曲。将挡板32设置为圆弧形使挡板32与卷曲后的柔性显示面板2之间的缝隙较小,进一步避免覆盖层31a的翘起;而且在柔性显示组件卷曲时,为后续缠绕于挡板32上的柔性显示组件提供一较为圆滑的基础面。
进一步的,本示例实施方式还提供了一种柔性显示装置,参照图4、图5和图6所示的柔性显示装置的结构示意图,该柔性显示装置可以包括上述任意一项所述的柔性显示组件。柔性显示组件的具体结构上述已经进行了详细说明,因此,此处不再赘述。
在本示例实施方式中,该柔性显示装置可以是卷曲式的显示装置,柔性显示装置还可以包括卷轴8,卷轴8可以通过双面胶9连接于支撑件1的第一端的远离柔性显示面板2的一侧。卷轴8可以转动,卷轴8转动即可带动柔性显示组件展开或收卷。卷轴8可以设置为圆柱形。当然,在本公开的其他示例实施方式中,卷轴8还可以设置为棱柱状。周向拉力主要由与卷轴8固定的材料传导,支撑件1与卷轴8固定相较于覆盖层组3与卷轴8固定,使覆盖层组3整体应力较小,从而改善HC膜层受拉产生裂纹的问题。
另外,需要说明的是,柔性显示装置可以是折叠式的显示装置,在折叠式的显示装置中柔性显示组件的第一端可以粘接在中框上。而且同样能够达到减小折弯后应力的作 用。
在安装该柔性显示装置时,可以先将柔性显示组件全部安装好然后再通过双面胶9粘接在卷轴8上。
在图6所示的示例实施方式中,挡板32的长度方向的两端可以铰接于卷轴8的两端,使在未安装显示面板前挡板32可以相对于卷轴8转动。具体为,可以在挡板32的长度方向的两端分别设置与挡板32垂直的连接板,在连接板上设置铰接通孔,在卷轴8的两端面设置铰接盲孔,铰接轴通过铰接通孔和铰接盲孔将连接板与卷轴8铰接。
而该柔性显示装置的具体类型不受特别的限制,本领域常用的显示装置类型均可,具体例如手机等移动装置、手表等可穿戴设备、VR装置等等,本领域技术人员可根据该显示设备的具体用途进行相应地选择,在此不再赘述。
需要说明的是,该柔性显示装置除了上述柔性显示组件以外,还包括其他必要的部件和组成,具体例如外壳、电路板、电源线,等等,本领域技术人员可根据该显示装置的具体使用要求进行相应地补充,在此不再赘述。
与现有技术相比,本公开示例实施方式提供的柔性显示装置的有益效果与上述示例实施方式提供的柔性显示组件的有益效果相同,在此不做赘述。
进一步的,本示例实施方式还提供了一种柔性显示装置的制备方法,用于制备图6所示的柔性显示装置,参照图7所示的本公开柔性显示装置的制备方法的流程示意框图。该柔性显示装置的制备方法可以包括以下步骤:
步骤S10,提供一卷轴8,所述卷轴8上可转动的连接有所述挡板32。
步骤S20,提供一柔性显示组件,所述柔性显示组件包括依次层叠设置的支撑件1、柔性显示面板2以及覆盖层31a。

具体地,可以先将挡板32铰接在卷轴8上,使挡板32可以转动。柔性显示组件可以包括依次层叠设置的支撑件1、柔性显示面板2以及覆盖层31a,支撑件1的第一端突出于柔性显示面板2以及覆盖层31a的第一端,覆盖层31a的第一端突出于柔性显示面板2的第一端。再转动挡板32,使挡板32与卷轴8之间形成夹角,夹角可以大于等于60度且小于等于90度,夹角的大小不限于上述说明,能够使柔性显示组件顺利伸入挡 板32与卷轴8之间形成夹角即可。然后,将支撑件1的第一端的远离柔性显示面板2的一面通过双面胶9粘接于卷轴8。最后,在支撑件1的第一端的远离卷轴8的一面涂覆粘接部4,向相反方向转动挡板32,使挡板32与粘接部4粘接,且使挡板32搭设于覆盖层31a的远离所述支撑件1的一侧。
