Description

显示装置及电子设备 技术领域
本申请涉及电子产品技术领域，尤其涉及一种显示装置及电子设备。
背景技术
近年来，柔性显示屏受到越来越多的关注，并被广泛使用。由于柔性显示屏具有轻薄、不易碎等特点，所以可以被使用在具有可折叠或可卷曲功能的装置上，例如被应用于手机等终端产品上。
区别于曾经出现的翻盖手机，折叠屏手机屏幕更大，两侧均有显示屏，显示屏可折叠，既可以满足用户对于大屏手机需求，又可以实现折叠后尺寸小，易于收纳携带。然而，柔性显示屏是多层材料复合结构，各层材料间是通过胶材或者镀层等方式结合在一起，所以在弯曲或者弯折过程中，如果弯折半径过小或者弯曲形态不规则偏向一边，都可能会出现显示屏在弯折区断裂的问题。
另外，现有技术中，整个柔性显示屏的各区域都只能有相同的折弯半径，这也成为制约产品结构设计的重要因素。
申请内容
本申请的目的在于提供一种显示装置及电子设备，改善了柔性显示屏在弯折过程中受力状态，解决了柔性显示屏在弯折过程中容易出现破裂的问题，提高了柔性显示屏的可靠性，延长了柔性显示屏的使用寿命，提高了电子设备的质量。
上述目标和其他目标将通过独立权利要求中的特征来达成。进一步的实现方式在从属权利要求、说明书和附图中体现。
第一方面，提供一种显示装置，包括：
柔性显示屏，包括屏本体和背膜，所述屏本体包括至少两第一弯折区，所述背膜包括至少两第二弯折区；各所述第二弯折区分别连接于相应的第一弯折区；
弯折支撑部，连接于各所述第二弯折区远离所述第一弯折区的一侧，以限定各所述第一弯折区的弯曲形态。
在上述方案中，在柔性显示屏背部设置弯折支撑部，限定了柔性显示屏的弯曲形态，改善了柔性显示屏在弯折过程中受力状态，解决了柔性显示屏在弯折过程中容易出现破裂的问题，提高了柔性显示屏的可靠性，延长了柔性显示屏的使用寿命，提高了电子设备的产品质量。
在一种可能的实施方案中，各所述第一弯折区中至少有两第一弯折区的弯曲形态不同；其中，所述弯曲形态包括弯曲长度和弯曲半径。
现有技术中同一柔性显示屏整个区域具有相同的弯折半径，从而制约了电子产品的结构设计。在本申请实施方案中，柔性显示屏可以具有两个，甚至两个以上的弯折区，且 各弯折区在弯折支撑部的支撑下可以具有不同的弯曲形态，从而拓展了柔性显示屏的应用范围，支持了电子产品多样化的结构设计。
在一种可能的实施方案中，所述显示装置包括至少两弯折支撑部，各所述弯折支撑部分别连接于各所述第二弯折区。
在上述方案中，在该实施方案中，分别针对各第二弯折区设置独立的弯折支撑部，各弯折支撑部分别改变柔性显示屏各弯折区的刚度，从而限定相应第一弯折区的弯曲形态，改变其弯折过程中的受力状态，防止各第一弯折区出现弯折裂屏的情况，延长了显示装置的使用寿命。
在一种可能的实施方案中，各所述弯折支撑部中至少有两弯折支撑部的延伸长度不同。
在上述方案中，弯折支撑部的延伸长度不同，则使得各弯折支撑部对应的第一弯折区的弯曲长度、弯曲半径不同，以满足不同的设计需求，为电子设备的多样化设计提供了技术支持。其中关于弯折支撑部的延伸长度，可以理解为弯折支撑部的中心线的长度。
在一种可能的实施方案中，各所述弯折支撑部中至少有两弯折支撑部的材质不同，且所述弯折支撑部的材质为金属、硅胶或树脂。
在上述方案中，弯折支撑部的材质不同，则相应的力学性能不同，如韧性、硬度不同，从而可限定柔性显示屏的各第一弯折区分别具有不同的弯曲形态。例如，采用金属材质制成的弯折支撑部的韧性、硬度高于采用硅胶制成的弯折支撑部。因此在其他条件相同的情况，金属材质制成的弯折支撑部对应的第一弯折区的弯曲半径大于硅胶制成的弯折支撑部对应的另一第一弯折区的弯曲半径。
在一种可能的实施方案中，各所述弯折支撑部均为片状体，各所述弯折支撑部中至少有两弯折支撑部的厚度不同。
在该实施方案中，即使各弯折支撑部的延伸长度和材质均相同，但是当各弯折支撑部的厚度不同时，则同样会使得各第一弯折区的弯曲形态不同。
第二方面，本申请提供一种电子设备，包括壳部，还包括上述的显示装置，所述背膜连接于所述壳部。
在一种可能的实施方案中，所述第二弯折区与所述壳部之间形成有容纳空间，所述弯折支撑部位于所述容纳空间内，连接于所述柔性显示屏且与所述壳部具有间隙。
在上述方案中，弯折支撑部与壳部之间具有间隙，在柔性显示屏弯曲过程中，弯折支撑部不会与壳部之间产生干涉，柔性显示屏在弯曲过程中仅依靠弯折支撑部本身结构提供支撑力，并不会受到壳部的强行拉伸，因此对柔性显示屏具有保护作用，防止柔性显示屏出现脱胶分层的问题。
在一种可能的实施方案中，所述壳部包括至少两折叠组件和多个板体；
每一折叠组件对应一所述第二弯折区；
相邻两板体之间通过所述折叠组件连接；
所述板体连接于所述背膜，所述折叠组件与所述弯折支撑部具有间隙。
在上述方案中，各板体之间通过折叠组件连接，各板体之间可相对转动弯折，从而带动显示装置弯折。弯折支撑部与板体和折叠组件均不接触。
在一种可能的实施方案中，所述板体通过胶层连接于所述背膜；
所述胶层包括双面胶、丙烯酸胶粘剂、橡胶粘合剂、硅胶粘合剂中的任意一种或多种的组合。
在上述方案中，胶层的固化工艺可以是紫外线固化，湿气固化、热固化或者红外固化。
本申请提供的技术方案可以达到以下有益效果：
本申请中，在柔性显示屏背部设置弯折支撑部，限定了柔性显示屏的弯曲形态，改善了柔性显示屏在弯折过程中受力状态，解决了柔性显示屏在弯折过程中容易出现破裂的问题，提高了柔性显示屏的可靠性，延长了柔性显示屏的使用寿命，提高了电子设备的产品质量。

具体实施方式
在本申请实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。在本申请实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。
需要注意的是，本申请实施例所描述的“上”、“下”、“左”、“右”等方位词是以附图所示的角度来进行描述的，不应理解为对本申请实施例的限定。此外，在上下文中，还需要理解的是，当提到一个元件连接在另一个元件“上”或者“下”时，其不仅能够直接连接在另一个元件“上”或者“下”，也可以通过中间元件间接连接在另一个元件“上”或者“下”
参见图1所示，为本申请实施例提供的一种显示装置10的结构示意图，该显示装置10包括柔性显示屏1和弯折支撑部2。柔性显示屏1包括屏本体11和背膜12，屏本体11包括至少两第一弯折区11a，背膜12包括至少两第二弯折区12a，各第二弯折区12a分别连接于相应的第一弯折区11a。弯折支撑部2连接于各第二弯折区12a远离第一弯折区11a的一侧，以限定各第一弯折区11a的弯曲形态。
参见图2和图3所示，为柔性显示屏1的弯折状态仿真图。其中，图2为柔性显示屏1上未设置弯折支撑部2时的弯曲形态图；图3为柔性显示屏1上设置弯折支撑部2时的弯曲形态图。对比两个图可以明显地看出，图3中通过在柔性显示屏1上设置弯折支撑部2，使得相应弯折区的弯曲半径变大，从而保护了柔性显示屏1的弯折区，有效的防止了弯折区弯折过度而出现断裂碎屏的情况。
柔性显示屏1是多层材料组成的复合结构，各层材料之间是通过胶材或者镀层等方式结合在一起，所以在柔性显示屏1弯折的过程中，如果弯折半径过小或者弯曲形态不规则偏向一边，都可能会使得柔性显示屏1在弯折区出现断裂碎屏的情况。本申请所提供的实施例中，在柔性显示屏1背部设置弯折支撑部2，限定了柔性显示屏1的弯曲形态，改善了柔性显示屏1在弯折过程中受力状态，解决了柔性显示屏1在弯折过程中容易出现破裂的问题，提高了柔性显示屏1的可靠性，延长了柔性显示屏1的使用寿命。
另外，本实施方案中，背膜12为柔性材料制成，背膜12连接于屏本体11，而弯折支撑部2连接于背膜12，则在柔性显示屏1弯折的过程中，弯折支撑部2与屏本体11没有直接刚性接触，背膜12位于两者之间起到了缓冲的作用，从而保护了屏本体11，延长了柔性显示屏1的寿命。
参见图1所示，在一种可能的实施方案中，各第一弯折区11a中至少有两第一弯折区11a的弯曲形态不同，其中，弯曲形态包括弯曲长度和弯曲半径。
现有技术中同一柔性显示屏1整个区域具有相同的弯折半径，从而制约了电子产品的结构设计。在本申请实施方案中，柔性显示屏1可以具有两个，甚至两个以上的弯折区，且各弯折区在弯折支撑部2的支撑下可以具有不同的弯曲形态，从而拓展了柔性显示屏1的应用范围，支持了电子产品多样化的结构设计。
在一种可能的实施方案中，显示装置10包括至少两弯折支撑部2，各弯折支撑部2分别连接于各第二弯折区12a。
在该实施方案中，分别针对各第二弯折区12a设置独立的弯折支撑部2，各弯折支撑部2分别改变柔性显示屏1各弯折区的刚度，从而限定相应第一弯折区11a的弯曲形态，改变其弯折过程中的受力状态，防止各第一弯折区11a出现弯折裂屏的情况，延长了显示装置10的使用寿命。
参见图1所示，在一种可能的实施方案中，各弯折支撑部2中至少有两弯折支撑部2的延伸长度不同。
在该实施方案中，各弯折支撑部2的延伸长度不同，则使得各弯折支撑部2对应的第一弯折区11a的弯曲长度、弯曲半径不同，以满足不同的设计需求，为电子设备100的多样化设计提供了技术支持。其中关于弯折支撑部2的延伸长度，参见图4所示，可以理解为弯折支撑部2的中心线L的长度。
在一种可能的实施方案中，各弯折支撑部2中至少有两弯折支撑部2的材质不同，且弯折支撑部2的材质为金属、硅胶或树脂。
在该实施方案中，弯折支撑部2的材质不同，则相应的力学性能不同，如韧性、硬度不同，从而可限定柔性显示屏1的各第一弯折区11a分别具有不同的弯曲形态。例如，采用金属材质制成的弯折支撑部2的韧性、硬度高于采用硅胶制成的弯折支撑部2。因此在其他条件相同的情况，金属材质制成的弯折支撑部2对应的第一弯折区11a的弯曲半径大于硅胶制成的弯折支撑部2对应的第一弯折区11a的弯曲半径。
在一种可能的实施方案中，各弯折支撑部2均为片状体，各弯折支撑部2中至少有两弯折支撑部2的厚度不同。
在该实施方案中，即使各弯折支撑部2的延伸长度和材质均相同，但是当各弯折支撑部2的厚度不同时，则同样会使得相应的各第一弯折区11a的弯曲形态不同。
参见图5所示，在一种可能的实施方案中，显示装置10还包括柔性盖板3，柔性盖板3覆盖于屏本体11的外表面，可随着屏本体11一体弯曲，该柔性盖板3具有保护屏本体11的作用。
参见图5和图6所示，本申请实施例还提供一种电子设备100，该电子设备100包括壳部20以及上述的显示装置10，显示装置10上的背膜12连接于壳部20。
在一种可能的实施方案中，第二弯折区12a与壳部20之间形成有容纳空间c，弯折支撑部2位于容纳空间c内，连接于柔性显示屏1且与壳部20具有间隙。
在该实施方案中，弯折支撑部2与壳部20之间具有间隙，在柔性显示屏1弯曲过程中，弯折支撑部2不会与壳部20之间产生干涉，柔性显示屏1在弯曲过程仅依靠弯折支撑部2本身提供支撑力，不会受到壳部20的强行拉伸。该实施方案避免了壳部20在弯折过程中，多个部位对柔性显示屏1施加了牵伸力，因此对柔性显示屏1具有保护的作用，防止柔性显示屏1出现脱胶分层的问题。
参见图5所示，在一种可能的实施方案中，壳部20包括至少两折叠组件201和多个板体202，每一折叠组件201对应一第二弯折区12a，相邻两板体202之间通过折叠组件201连接，板体202连接于背膜12，折叠组件201与弯折支撑部2具有间隙。
在该实施方案中，各板体202之间通过折叠组件201连接，各板体202之间可相对转动弯折，从而带动显示装置10弯折。在弯折过程中，弯折支撑部2与板体202和折叠组件201均不接触，仅依靠弯折支撑部2的本身结构限定柔性显示屏1的弯曲形态，柔性显示屏1可自由弯曲，不受到壳部20的干涉。
参见图5和图6所示，在一种可能的实施方案中，板体202通过胶层30连接于背膜12，胶层30包括双面胶、丙烯酸胶粘剂、橡胶粘合剂、硅胶粘合剂中的任意一种或多种的组合。其中，胶层的固化工艺可以是紫外线固化，湿气固化、热固化或者红外固化。
