本申请要求2019年12月13日在中国提交的申请号为201911289801.3、名称为“柔性显示面板及电子设备”的专利申请的优先权，其全部内容通过引用并入本文。
技术领域
本申请涉及显示的技术领域，特别涉及一种柔性显示面板及电子设备。
背景技术
一般的柔性曲面手机，其柔性显示面板具有在手机宽度方向上弯曲的曲面造型。但是，由于柔性显示面板的结构特征，其在手机的长度方向并没有弯曲，此也导致了手机的头部和底部的边框直接平铺在盖板玻璃(Cover Glass，CG)上，使得此类手机的屏占比无法进一步提高。
此外，由于柔性显示面板在长度方向没有弯曲，一般的柔性曲面手机的外观形态并没有变化，产品竞争力较低并且用户的体验效果也较差。
发明内容
本申请的目的在于提供一种柔性显示面板及电子设备，以解决现有柔性显示面板不能双向弯曲的问题。
为了解决上述技术问题，本申请提供了一种柔性显示面板，包括：主视部、以及绕所述主视部的边缘设置的第一侧视部和第二侧视部。所述第一侧视部沿着所述主视部的宽度方向弯曲，所述第二侧视部沿着所述主视部的长度方向弯曲。所述主视部的外轮廓包括拐角段；所述第一侧视部的外轮廓包括第一段以及第二段，所述第二段连接在所述第一段和所述拐角段之间。所述第二侧视部的外轮廓包括第三段以及第四段，所述第三段连接在所述第四段和所述拐角段之间。所述第二段、所述拐角段与所述第三段在整体上为相对所述主视部凸起的凸弧状。由此，柔性显示面板的外轮廓在整体上更加自然，而不会在柔性显示面板的边角的区域出现过渡不自然的缺口或者凹陷，以提高用户的使用体验。

一种可能的实施方式中，所述第一段和所述第四段均呈直线状，所述第二段圆滑连接在所述第一段和所述拐角段之间，所述第三段圆滑连接在所述第四段和所述拐角段之间。由此，在满足长度方向和宽度方向弯曲的同时，该柔性显示面板还在角落的位置可以呈现出对称且 平滑过渡的线条，以提高用户的使用体验。
一种可能的实施方式中，所述第二段、所述拐角段与所述第三段依次连接形成基于贝塞尔曲线的凸弧状。应当理解，通过贝塞尔曲线来对柔性显示面板的外轮廓进行限定，可以使第一侧视部、第二侧视部和主视部之间的过渡更为圆滑自然，而不会因为过渡不自然而在柔性显示面板的边缘出现凸起或者凹陷。
一种可能的实施方式中，所述拐角段呈圆弧形曲线，以所述拐角段的中点所在的半径方向的线为中心线，所述第二段和所述第三段对称分布在所述中心线的两侧。以此，第一侧视部、第二侧视部和主视部之间的过渡更为圆滑自然，而不会因为过渡不自然而在柔性显示面板的边缘出现凸起或者凹陷。
本申请提供了一种电子设备，包括：设备主体、以及上述的柔性显示面板。所述柔性显示面板设于所述设备主体上。应当理解，设备主体可以包括必要的或者非必要的处理器、摄像头和扬声器等组件。柔性显示面板显示由设备主体传输的画面。由此，通过具有主视部、第一侧视部和第二侧视部的柔性显示面板，该电子设备可以提供更为真实的显示效果，以提高用户的体验效果以及产品竞争力。
一种可能的实施方式中，所述电子设备还包括盖板，所述盖板盖合于所述柔性显示面板之远离所述设备主体的一侧。所述盖板包括：主体部、以及绕所述主体部的边缘设置的第一弯曲部和第二弯曲部；所述第一弯曲部沿着所述主体部的宽度方向弯曲，所述第二弯曲部沿着所述主体部的长度方向弯曲；所述主体部的外轮廓包括缓冲段；所述第一弯曲部的外轮廓包括第五段以及第六段，所述第六段连接在所述第五段和所述缓冲段之间；所述第二弯曲部的外轮廓包括第七段以及第八段，所述第七段连接在所述第八段和所述缓冲段之间；所述第六段、所述缓冲段与所述第七段在整体上为相对所述主视部凸起的凸弧状。

具体实施方式
下面将结合本申请实施方式中的附图，对本申请实施方式中的技术方案进行清楚、完整地描述。
请同时参考图1至图13，本申请各实施例提供的柔性显示面板100以及电子设备10，以解决常态的柔性显示面板不能实现长度方向和宽度方向上同时弯曲的问题，并由此提高使用该柔性显示面板的电子设备的体验效果。以OLED(Organic Light-Emitting Diode，发光二极管)面板的柔性显示面板、以及手机的电子设备为例进行说明，常态的OLED面板是在手机的宽度方向上进行弯曲设计，由此使OLED面板可以呈现出3D的显示效果。而当OLED面板在宽度方向上弯曲，也会导致该OLED面板无法在长度方向上实现弯曲。若强行在OLED面板的长度方向上弯曲，则会导致OLED面板的边缘形成褶皱。而褶皱的OLED面板属于有缺陷的面板，并不能用在实际的电子设备中。
请同时参考图1和图2，基于以上示出的问题，本申请提供的一种柔性显示面板100。该柔性显示面板100包括主视部110和侧视部(121，122)。主视部110在整体上大致呈现为平面的矩形形状。侧视部(121，122)则相对该主视部110弯曲，并且在侧视部(121，122)的表面在整体上呈现为圆滑过渡的弧形面的形状。应当理解，侧视部(121，122)弯曲的方向是指朝向远离主视部110的显示面的方向，该显示面是主视部110或柔性显示面板100呈现画面的一面。
柔性显示面板100在侧视部(121，122)的边缘还设有电路连接端123，该电路连接端123用于与FPC(Flexible Printed Circuit，柔性电路板)等组件连接，以使柔性显示面板100可以呈现出经FPC传输过来的画面及信息。基于此，当柔性显示面板100应用于电子设备10时，主视部110为用户查看柔性显示面板100的主要部分，侧视部(121，122)为用户查看柔性显示面板100的次要部分。基于此，主视部110位于该柔性显示面板100的中部；相对侧视部(121，122)，主视部110具有较大的面积，以供用户获取柔性显示面板100呈现的画面及信息。
一种可能的实施方式中，主视部110和侧视部(121，122)是指柔性显示面板100的一体成型的两部分。比如：通过对制造过程中的柔性显示面板100的边角进行削切处理，以形成本申请各实施例中的具有主视部110和侧视部(121，122)的柔性显示面板100。
一种可能的实施方式中，当本申请各实施例的柔性显示面板100应用在电子设备10中并呈现供用户欣赏的画面时，主视部110和侧视部均用来显示，并且相对主视部110，侧视部(121，122)是更靠近电子设备10后盖或者更远离用户的显示区域。主视部110和侧视部共同配合而柔性显示面板100在整体上呈现出3D的显示效果。由于本申请各实施例的侧视部(121，122)在电子设备10的长度方向和宽度方向上弯曲，由此柔性显示面板100可以提供更为真实的3D效果，以提高用户对该电子设备10的使用体验。
应当理解，电子设备10的长度方向和柔性显示面板100的长度方向b是一致的，长度方向b即是指电子设备10或者柔性显示面板100的长边的方向；相应的，电子设备10的宽度方向和柔性显示面板100的宽度方向a也是一致的，宽度方向a即是指电子设备10或者柔性显示面板100的短边的方向。即，本申请各实施例中所指的柔性显示面板100的长度方向b，也可以指代电子设备10的长度方向。类比的，本申请各实施例中所指的柔性显示面板100的宽度方向a，也可以指代电子设备10的宽度方向。
请同时参考图3和图4，一种可能的实施方式中，侧视部(121，122)包括相对主视部110弯曲的第一侧视部121和第二侧视部122。第一侧视部121和第二侧视部122沿着主视部110的不同方向弯曲。第一侧视部121沿着主视部110的宽度方向b弯曲，第二侧视部122沿着主视部110的长度方向a弯曲。第一侧视部121和第二侧视部122均绕该主视部110的边缘设置。相应的，为了消除常态的柔性显示面板在长度方向a和宽度方向b上同时弯曲时由于交汇所产生的褶皱，主视部110的外轮廓包括拐角段111，该拐角段111连接在第一侧视部121和第二侧视部122之间。
请同时参考图3和图4，第一侧视部121的外轮廓包括平滑过渡的第一段121a和第二段121b。第二段121b连接在第一段121a和拐角段111之间，并且随着靠近拐角段111，该第二段121b也逐渐靠近主视部110，以使第二段121b和拐角段111之间平滑过渡。对应于该第一侧视部121，第二侧视部122的外轮廓包括平滑过渡的第三段122a和第四段122b，第三段122a连接在拐角段111和第四段122b之间，并且随着靠近拐角段111，该第三段122a也逐渐靠近主视部110，以使第三段122a和拐角段111之间平滑过渡。第四段122b处设有电路连接端123，用于连接FPC。
本申请各实施例中的柔性显示面板100，是对常态的柔性显示面板中容易产生褶皱的区域进行处理。比如：对该容易产生褶皱的区域进行削切处理，并在削切掉的褶皱的区域暴露出部分主视部110，该暴露出的部分主视部110的外轮廓即为拐角段111。由此，通过该拐角段111，即使第一侧视部121和第二侧视部122分别在宽度方向b和长度方向a上弯曲也不会 交汇，以此预防第一侧视部121和第二侧视部122弯曲而产生褶皱。由此，基于主视部110、第一侧视部121和第二侧视部122的配合，柔性显示面板100可以实现长度方向a和宽度方向b上的弯曲。
应当理解，为了便于理解本申请的技术方案，本申请的各实施例的柔性显示面板100的显示面大致上为矩形，即，第一侧视部121和第二侧视部122的数量均为两个。两个第一侧视部121相对设置，两个第二侧视部122相对设置。两个第二侧视部122的两端分别通过拐角段111连接至对应的第一侧视部121。应当理解，两个第一侧视部121和两个第二侧视部122之间暴露出主视部110的四个拐角段111，以此该柔性显示面板100可以匹配常见的手机或者平板电脑。但是，并不以此限定本申请的柔性显示面板100仅能是矩形。该柔性显示面板100的显示面也可以大致上为三角形或者五边形等等；该柔性显示面板100所适用的电子设备10也不限于手机或者平板电脑，还可以是车载导航仪或者人脸识别设备等等。
为了使柔性显示面板100在整体上更加自然，以提高使用该柔性显示面板100的电子设备10的体验效果，第二段121b、拐角段111和第三段122a在整体上能够呈现出相对主视部110凸起的凸弧形态。应当理解，沿着该柔性显示面板100的对角线的方向，拐角段111是处于最前或者最后的部分，即拐角段111是位于柔性显示面板100的角落。
可预知的，当用户拿起手机等类型的电子设备10时，该电子设备10的正面是用户主要观察的区域。而电子设备10的正面的整体轮廓主要是受显示面板的轮廓影响的，相应的，中框的构造也是跟随显示屏的形状而定；此外，对于常态的追求更高屏占比(比如：窄边框设计或者全面屏设计)的电子设备10更是如此。对此，本申请各实施例中的柔性显示面板100将第二段121b、拐角段111和第三段122a的外轮廓设置成凸弧的形状，由此，当该柔性显示面板100应用在电子设备10中时，该电子设备10的正面在边角的区域并不会出现过渡不自然的缺口或者凹陷，以更符合用户的使用习惯。
一种可能的实施方式中，第一段121a和第四段122b均呈直线状，或者该第一段121a和该第四段122b理解为线段。第二段121b圆滑连接在第一段121a和拐角段111之间，第三段122a圆滑连接在第四段122b和拐角段111之间。应当理解，第二段121b和第三端122a为曲线状，以使得柔性显示面板100在角落的区域呈现出圆滑过渡的效果。
一种可能的实施方式中，第二段121b、拐角段111和第三段122a依次连接形成基于贝塞尔曲线的凸弧的形状。应当理解，贝塞尔曲线的控制点均是位于该贝塞尔曲线之远离主视部110的一侧。而通过贝塞尔曲线来对柔性显示面板100的外轮廓进行限定，可以使第一侧视部121、第二侧视部122和主视部110之间的过渡更为圆滑自然，而不会因为过渡不自然而在柔性显示面板100的边缘出现凸起或者凹陷。
请参考图4，一种可能的实施方式中，拐角段111呈圆弧形曲线，以拐角段111的中点O所在的半径方向的线为中心线，第二段121b和所述第三段122a对称分布在所述中心线的两侧。应当理解，通过相对中点O对称分布的第二段121b和所述第三段122a，在满足长度方向a和宽度方向b弯曲的同时，该柔性显示面板100还在角落的位置可以呈现出对称且平滑过渡的线条，以提高用户的使用体验。
请再参考图3和图4，一种可能的实施方式中，主视部110包括第一长边110a和第一短边110b。该第一长边110a、拐角段111和第一短边110b依次相连并以此界定出该主视部110的形状和大小。应当理解，第一长边110a是主视部110和第一侧视部121的共用边界，第一短边110b是主视部110和第二侧视部122的共用边界。第一长边110a和第一短边110b延长 而相交的交点N位于柔性显示面板100外，以此降低第一侧视部121和第二侧视部122由于弯曲过量而导致褶皱产生的可能。
一种可能的实施方式中，第一侧视部121的长度小于主视部110的长度；第二侧视部122的长度小于主视部110的宽度。由此，主视部110长于第一侧视部121以及主视部110长于第二侧视部122所形成的区域即为包括如上所描述的拐角段111的区域。基于此，第一侧视部121和第二侧视部122之间不接触，以便于对第一侧视部121和第二侧视部122进行弯曲处理。
请同时参考图5和图6，一种可能的实施方式中，基于所需的显示效果的不同，第一侧视部121与主视部110之间的夹角α大于0°并且小于或者等于89°。应当理解，该夹角α为0°到89°之间的任意角度，比如，该夹角α为10°、20°、30°、40°、50°、60°、70°或80°。应当理解，第一侧视部121与主视部110之间的夹角α越大，则柔性显示面板100呈现的3D效果也更为真实；相应的，第一侧视部121与主视部110之间的弯曲更为明显，柔性显示面板100的可视角度也相应增大。由此，该柔性显示面板100可以根据使用需求而提供不同的视觉体验。
请同时参考图7和图8，一种可能的实施方式中，类比于第一侧视部121与主视部110之间的夹角α，第二侧视部122与主视部110之间的夹角β大于0°并且小于或者等于89°。应当理解，该夹角β为0°到89°之间的任意角度，比如，该夹角β为10°、20°、30°、40°、50°、60°、70°或80°。图7底部示出了连接至第二侧视部122的第四段122b处的电路连接端123，用于连接FPC。
请参考图9，本申请实施例还提供了一种电子设备10，该电子设备10包括：设备主体300、盖板200、以及上述各实施例中的柔性显示面板100。设备主体300可以包括必要的或者非必要的处理器、摄像头和扬声器等组件，对此不做限制。柔性显示面板100设于设备主体300上，并与设备主体300电连接，以显示由设备主体300传输的画面。盖板200与柔性显示面板100相贴合，并使柔性显示面板100位于设备主体300和盖板200之间，以此保护该柔性显示面板100。通过具有主视部110、第一侧视部121和第二侧视部122的柔性显示面板100，该电子设备10可以提供更为真实的3D显示效果，以提高用户的体验效果以及产品竞争力。
请同时参考图9至图12，本申请实施例提供的盖板200可以与上述各实施例中的柔性显示面板100相适配，以盖合在柔性显示面板100的显示一侧并保护该柔性显示面板100。对应于以上各实施例中的柔性显示面板100，该盖板200包括：主体部210、第一弯曲部221和第二弯曲部222。该主体部210在整体上大致呈现为平面的形状。第一弯曲部221和第二弯曲部222则相对该主体部210弯曲，并且在整体上呈现为圆滑过渡的弧形面的形状。应当理解，盖板200的主体部210是与柔性显示面板100的主视部110相对应的部分，盖板200的第一弯曲部221和第二弯曲部222是分别与柔性显示面板100的第一侧视部121和第二侧视部122相对应的部分，以实现无间隙或无气泡贴合。
一种可能的实施方式中，主体部210、第一弯曲部221和第二弯曲部222是指盖板200的一体成型的部分。以玻璃盖板200为例进行说明，通过石墨模具等类型的模具对制造过程中的未成形的玻璃材料进行弯曲处理，以形成具有主体部210、第一弯曲部221和第二弯曲部222的盖板200。
对应于以上实施例中的柔性显示面板100，盖板200的第一弯曲部221沿着主体部210 的宽度方向d弯曲，第二弯曲部222沿着主体部210的长度方向c弯曲。第一弯曲部221和第二弯曲部222均绕该主体部210的边缘设置。而为了消除在长度方向c和宽度方向d上同时弯曲时由于交汇所产生的褶皱，主体部210还具有的外轮廓包括缓冲段211，该缓冲段211连接在第一弯曲部221和第二弯曲部222之间。
一种可能的实施方式中，本申请实施例提供的盖板200为透明盖板200，该透明盖板200的可以是玻璃盖板或者蓝宝石盖板，应当理解，本申请对盖板200的材料不做限制。相应的，第一弯曲部221和第二弯曲部222弯曲的方向是指朝向主体部210同一侧的方向弯曲，由此，该向同一侧的方向弯曲的第一弯曲部221和第二弯曲部222可以与柔性显示面板100的第一侧视部121和第二侧视部122无间隙贴合，并避免产生气泡。
请参考图11，第一弯曲部221的外轮廓包括平滑过渡的第五段221a和第六段221b。第六段221b连接在第五段221a和缓冲段211之间，并且随着靠近缓冲段211，该第六段221b也逐渐靠近主体部210，以使第六段221b和缓冲段211之间平滑过渡。对应于该第一弯曲部221，第二弯曲部222的外轮廓包括平滑过渡的第七段222a和第八段222b，第七段222a连接在缓冲段211和第八段222b之间，并且随着靠近缓冲段211，该第七段222a也逐渐靠近主体部210，以使第七段222a和缓冲段211之间平滑过渡。由此，第六段221b、缓冲段211和第七段222a在整体上能够呈现出相对主体部210凸起的凸弧形态，以使盖板200能够与以上实施例中的柔性显示面板100相贴合。
一种可能的实施方式中，第六段221b、缓冲段211和第七段222a依次连接而形成基于贝塞尔曲线的凸弧的形状。应当理解，贝塞尔曲线的控制点均是位于该贝塞尔曲线之远离主体部210的一侧。而通过贝塞尔曲线来对盖板200的外轮廓进行限定，可以使第一弯曲部221、第二弯曲部222和主体部210之间的过渡更为圆滑自然，而不会因为过渡不自然而在盖板200的边缘出现凸起或者凹陷，以提高用户的体验效果。
请参考图11，一种可能的实施方式中，主体部210包括第二长边210a和第二短边210b。该第二长边210a、缓冲段211和第二短边210b依次相连并由此界定出该主体部210的形状和大小。应当理解，第二长边210a是主体部210和第一弯曲部221的共用边界，第二短边210b是主体部210和第二弯曲部222的共用边界。第二长边210a和第二短边210b延长而相交的交点M位于盖板200外，以此降低第一弯曲部221和第二弯曲部222由于弯曲过量而导致盖板200产生裂痕或者导致废品的可能。
一种可能的实施方式中，第一弯曲部221的长度小于主体部210的长度，第二弯曲部222的长度小于主体部210的宽度。由此，主体部210长于第一弯曲部221以及主体部210长于第二弯曲部222所形成的区域即为包括如上所描述的缓冲段211的区域。基于此，第一弯曲部221和第二弯曲部222之间不接触，以便于通过模具对第一弯曲部221和第二弯曲部222进行热弯曲处理。
一种可能的实施方式中，基于所需的显示效果的不同以及实现与柔性显示面板100相贴合，第一弯曲部221与主体部210之间的夹角大于0°并且小于或者等于89°。即，该夹角为0°到89°之间的任意角度，比如，该夹角为10°、20°、30°、40°、50°、60°、70°或80°。应当理解，第一弯曲部221与主体部210之间的夹角越大，则，第一弯曲部221与主体部210之间的弯曲更为明显。一种可能的实施方式中，类比于第一弯曲部221，第二弯曲部222与主体部210之间的夹角大于0°并且小于或者等于89°。第二弯曲部222与主体部210之间的夹角为0°到89°之间的任意角度，比如，该夹角为10°、20°、30°、40°、50°、60°、70°或80°。
一种可能的实施方式中，当盖板200与柔性显示面板100组装在电子设备10中，柔性显示面板100呈现显示内容，盖板200位于显示面板的显示一侧或者位于显示面板之背对电子设备10内部的一侧。该盖板200对柔性显示面板100起到保护的作用，并且该盖板200也是与用户直接或间接接触的部件。对此，为了提供更为舒适的触感，并提高用户的体验效果，请参考图12，盖板200的第一弯曲部221的边缘具有2.5D处理的弧形过渡曲面。应当理解，该边缘是指第一弯曲部221之远离主体部210的边缘。类比的，第二弯曲部222的边缘也具有2.5D处理的弧形过渡曲面。通过具有2.5D处理的边缘的第一弯曲部221和第二弯曲部222，该盖板200可以跟电子设备10的中框等部件更为紧密地贴合，并使盖板200与中框等部件之间的过渡更为圆滑和自然，以便于用户拿取。
应当理解，2.5D处理是指对盖板的边缘进行削切等的特殊处理，以在盖板的边缘形成弧面，而盖板的中间部分仍为平面。整体上，2.5D处理的盖板的边缘呈现出圆滑过渡的形态。相对于平面类型的盖板，2.5D处理的盖板可以具有更强的抗摔能力。在用户使用该具有2.5D处理的盖板的电子设备时，用户的手掌会弯曲并与盖板的边缘接触，由此，具有2.5D处理的盖板可以更符合人体工程学原理。
相对主体部210弯曲的第一弯曲部221和第二弯曲部222还能够在一定程度上扩张柔性显示面板100所呈现的画面；基于此，具有2.5D处理的边缘的第一弯曲部221和第二弯曲部222可以使用户欣赏到的画面更趋向于3D的效果。
一种可能的实施方式中，在该盖板200还处于未定型的平面基板时，通过CNC(Computer Numerical Control，数字控制机床)来对该平面基板进行处理，以去掉该平面基板的棱角，并对去掉棱角后的平面基板的边缘进行打磨抛光处理，而在该平面基板的边缘形成2.5D的弧形过渡曲面。而后，通过石墨模具对该平面基板进行热弯曲，以形成具有主体部210以及具有2.5D边缘的第一弯曲部221和第二弯曲部222的盖板200。
一种可能的实施方式中，由于本申请提供的盖板200具备相对主体部210弯曲的第一弯曲部221和第二弯曲部222，由此，该盖板200可以作为以上实施例中柔性显示面板100的模具。比如：通过OCA(Optically Clear Adhesive，光学胶)等透明粘合剂将未弯曲的柔性显示面板100压合并固定至盖板200内。通过相对主体部210弯曲的第一弯曲部221和第二弯曲部222，而使得未弯曲的柔性显示面板100以贴合盖板200的表面的形式实现弯曲，以此来简化使用柔性显示面板100和盖板200的电子设备10的组装步骤。
请参考图13，一种可能的实施方式中，电子设备10还包括：偏光片400。该偏光片400被设置成具有与柔性显示面板100的表面相同的形状，以无间隙且无褶皱地与柔性显示面板100相贴合。对应的，对该偏光片400的角落进行去除处理，以形成凸弧的形状。在之后的工序中，再将盖板300设置在偏光片300上。
在其他的一种可能的实施方式中，本申请提供的盖板200可以与常态的显示面板相配合，以更好地保护该显示面板并使其可以提供更丰富的显示效果。
在其他的一种可能的实施方式中，本申请提供的盖板200除了与柔性显示面板100盖合外，还可以用在电子设备10的后盖上，以提高用户的使用体验。
以上所述是本申请具体的实施方式，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，这些改进和润饰也视为本申请的保护范围。
