详述
下文中将结合附图对本公开的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
图1为一种柔性显示面板的平面示意图，图2为图1所示柔性显示面板的柔性弯折部展开后的平面示意图，图3为图1中A-A的截面示意图。如图1、图2和图3所示，柔性显示面板包括显示区域100，在垂直于显示面板的平面A-A上，显示面板包括显示基板10以及设置在显示基板10的显示侧的盖板20。显示基板10包括凸出于显示区域100的柔性弯折部11。柔性弯折部11包括靠近显示区域100的弯折区域111以及远离显示区域100的绑定区域112。在一示例性的实施方式中，绑定区域112设置有多个用于与控制线路板绑定连接的绑定垫，弯折区域111设置有用于连接绑定垫与显示区域信号线的多条连接线。柔性弯折部11通过弯折区域111弯折后，隐藏在显示基板10的背离盖板20的一侧，如图3所示。
柔性显示面板通常可以在第一方向X和第二方向Y上弯折。图4为图1所示柔性显示面板在第一方向X上弯折后的截面示意图，图4中示出了柔性弯折部11的弯折区域111的位置。如图4所示，柔性显示面板在第一方向X上弯折后，显示基板10会受到沿第一方向X的弯折力，同时，由于显示基板10与盖板20的弯曲性能方面的差异，显示基板10的两侧还会受到来自盖板20弯折后对其产生的剪应力。因此，当显示面板如图4那样弯折时，柔性弯折部11的弯折区域会同时受到沿第一方向X的弯折力和来自盖板20弯折后对其产生的剪应力，另外，柔性弯折部11的弯折区域111还同时受到自身弯折的内弯折力(如图3所示)，这三种力同时作用在弯折区域111上，使得弯折区域111的受力加重，不利于弯折区域111的受力分散，极易导致弯折区域111产生裂纹，影响显示面板的正常显示。
本公开实施例提供了一种显示面板。该显示面板包括显示基板，所述显示基板包括显示区域以及凸出于显示区域的柔性弯折部，所述柔性弯折部包括靠近所述显示区域的弯折区域，所述柔性弯折部通过所述弯折区域弯折后隐藏在所述显示基板的背离显示侧的一侧，所述显示面板在第一方向上为可弯折面板，所述显示面板在第一方向上具有可弯折段和非弯折段，在第一方向上，所述弯折区域位于所述非弯折段限定的范围内，所述第一方向为与所述柔性弯折部相对于所述显示区域凸出的方向相垂直的方向。
本公开实施例的显示面板，当显示面板在第一方向上弯折时，非弯折段不会被弯折，弯折区域位于非弯折段的范围内，从而，弯折区域在第一方向上也不会被弯折，从而弯折区域不会受到沿第一方向的弯折力，同时，弯折区域由于位于可弯折段范围之外，弯折区域也不会受到来自显示面板其它膜层(例如盖板)弯折产生的剪应力，从而，弯折区域只受到自身弯折的内弯折力，使得弯折区域的受力大大减小，有利于弯折区域的受力分散，避免了弯折区域产生裂纹，保证了显示面板的正常显示。
下面将通过示例性的实施例说明本公开的技术方案。
图5为本公开一实施例显示面板的展开结构示意图。本公开实施例的显示面板的平面结构示意图如图1所示，显示面板的A-A截面结构示意图如图3所示，如图1、图3，和图5所示，显示面板包括显示基板10。显示基板 10包括显示区域100以及凸出于显示区域100的柔性弯折部11。柔性弯折部11包括靠近显示区域100的弯折区域111，柔性弯折部11通过弯折区域111弯折后，隐藏在显示基板10的背离盖板20的一侧。
图6为本公开实施例显示面板在第一方向上弯折后的截面结构示意图。将柔性弯折部11相对于显示区域100凸出的方向设为第二方向Y，第一方向X为与第二方向Y相垂直的方向，如图1所示。在第一方向X上，显示面板为可弯折面板。在第一方向X上，显示面板具有可弯折段和非弯折段33。在第一方向上，弯折区域111位于非弯折段限定的范围内。在图6中示出了弯折区域111的位置，弯折区域111位于非弯折段33在第一方向X上限定的范围内，也就是说，弯折区域111既可以位于非弯折段33在第一方向限定的范围的内侧，也可以与非弯折段33在第一方向限定的范围重合。
本公开实施例的显示面板，当显示面板在第一方向X上弯折时，非弯折段33不会被弯折，弯折区域111位于非弯折段33的范围内，从而，弯折区域111在第一方向X上也不会被弯折，从而弯折区域111不会受到沿第一方向X的弯折力，并且，弯折区域111由于位于可弯折段范围之外，弯折区域111也不会受到来自显示面板其它膜层(例如盖板)弯折产生的剪应力，从而，弯折区域111只受到自身弯折的内弯折力(如图3所示)，相比于图4所示，本公开实施例中，弯折区域111的受力大大减小，有利于弯折区域111的受力分散，避免了弯折区域111产生裂纹，保证了显示面板的正常显示。
在本实施例中，如图6所示，可弯折段包括在第一方向上分别位于显示面板两侧的第一可弯折段31和第二可弯折段32，非弯折段33位于第一可弯折段31和第二可弯折段32之间。这样的结构，符合客户对显示面板的弯折需求，并且，非弯折段33位于第一可弯折段31和第二可弯折段32之间，从而，弯折区域111也位于显示面板的中间位置，符合显示面板的正常制备结构，方便了显示面板的生产。
在其它实施例中，可弯折段和非弯折段可以在第一方向上任意设置，只要满足柔性弯折部的弯折区域位于非弯折段限定的范围内即可。例如，在第一方向上，显示面板的左侧部为可弯折段，右侧部为非弯折段，从而显示面 板的左侧部可以弯折在右侧部的上侧或下侧。
如图5和图6所示，显示面板还包括设置在显示基板10的显示侧的盖板20，盖板20的周向边缘凸出于显示区域100。显示面板在第一方向X上的尺寸为盖板20在第一方向X上的尺寸。
本公开实施例的显示面板，当显示面板在第一方向X上弯折时，非弯折段33不会被弯折，弯折区域111位于非弯折段33的范围内，从而，弯折区域111在第一方向X上不会被弯折，从而弯折区域111不会受到沿第一方向X的弯折力，并且，弯折区域111由于位于第一弯折段31和第二弯折段32之外，弯折区域111也不会受到来自盖板20弯折产生的剪应力，从而，弯折区域111只受到自身弯折的内弯折力(如图3所示)，相比于图4所示，本公开实施例中，弯折区域111的受力大大减小，有利于弯折区域111的受力分散，避免了弯折区域111产生裂纹，保证了显示面板的正常显示。
在一个实施例中，弯折区域111在第一方向X上的尺寸为显示面板在第一方向X上的尺寸的1/4～1/2。在一个实施例中，弯折区域111在第一方向X上的尺寸为显示面板在第一方向X上的尺寸的1/3。
在本实施例中，如图6所示，非弯折段33在第一方向上的范围与弯折区域111在第一方向X上的范围重合，均为显示面板在第一方向X上尺寸的1/3。
在本实施例中，第一可弯折段31和第二可弯折段32对称设置在显示面板的两侧。非弯折段33和弯折区域111也呈对称设置，如图6所示。
在一个实施例中，如图5所示，柔性弯折部11还包括位于弯折区域111的背离显示区域100一侧的绑定区域112。在第一方向上，绑定区域112的尺寸大于弯折区域111的尺寸。
在图5中，弯折区域111在第一方向X上的尺寸为M1，绑定区域112在第一方向X上的尺寸为M2。在图2中，弯折区域111在第一方向X上的尺寸与绑定区域112在第一方向X上的尺寸相等，均为M0。在一个实施例中，绑定区域112设置有用于与控制线路板绑定连接的多个绑定垫，弯折区域111设置有用于连接绑定垫与显示区域信号线的多条连接线，连接线可以 包括VSS连接线、VDD连接线、数据线(Data线)引线等。为了将弯折区域111在第一方向X上的尺寸由M0缩减到M1，可以在工艺允许的范围内，减小弯折区域111连接线的宽度以及相邻连接线之间的间距，从而，缩小弯折区域111在第一方向X上的尺寸，以使得弯折区域111避开显示面板的在第一方向X上的可弯折段。绑定垫的尺寸和间距不容易改变，因此，M2可以等于M0，以实现绑定区域112的有效绑定。
在一个实施例中，柔性弯折部11还包括设置在弯折区域111与绑定区域112之间的过渡区域113。过渡区域113的侧边为直线边，如图5所示。
图7为另一个实施例中显示面板的展开结构示意图。在另一个实施例中，如图7所示，柔性弯折部11还包括设置在弯折区域111与绑定区域112之间的过渡区域113。过渡区域113的侧边为曲线边，可以为外凸的曲线边，也可以为内凹的曲线边，或者为不规则形状的曲线边等。
在一示例性的实施方式中柔性弯折部也可以不设置过渡区域，而是弯折区域和绑定区域直接连接。
在另一个实施例中，本公开实施例的显示面板在第二方向Y上也为可弯折面板，从而，本公开实施例的显示面板为四面可弯折面板。
基于前述示例性实施例的发明构思，本公开实施例还提供了一种显示装置，该显示装置包括采用前述实施例的显示面板。显示装置可以为：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。
在本公开实施例的描述中，需要理解的是，术语“中部”、“上”、“下”、“前”、“后”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本公开和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本公开的限制。
在本公开实施例的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以 是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本公开中的具体含义。
虽然本公开所揭露的实施方式如上，但所述的内容仅为便于理解本公开而采用的实施方式，并非用以限定本公开。任何本公开所属领域内的技术人员，在不脱离本公开所揭露的精神和范围的前提下，可以在实施的形式及细节上进行任何的修改与变化，但本公开的专利保护范围，仍须以所附的权利要求书所界定的范围为准。
