Description

可折叠屏幕以及折叠屏移动终端
本申请要求于2020年11月26日提交至中国国家知识产权局、申请号为202011356245.X、发明名称为“可折叠屏幕以及折叠屏移动终端”的专利申请的优先权。
技术领域
本申请涉及折叠屏技术，尤其涉及一种可折叠屏幕以及折叠屏移动终端。
背景技术
随着科技的进步，智能手机等移动电子设备得到迅猛发展，对于智能手机而言，其所发挥的作用也越来越大，为了提升智能手机的使用便利性，大尺寸屏幕是一种主流发展趋势，而为了兼顾便携性，折叠屏应运而生。但是，目前折叠屏手机的折叠和展开过程均需人工手动操作，使用过程极为不便。
现有折叠屏手机中，继三星第二代折叠手机和华为Mate X发布以来，几乎各大手机厂商都在大力研发折叠智能手机。目前市面上的折叠手机折叠方式可大致分为四种：
(1)例如，型号为Samsung Galaxy Fold的折叠屏手机，采用的左右内折方式，屏幕分布在左右两块机壳上，合上手机时屏幕折在内部。
(2)例如，华为型号为Mate X的折叠屏手机，采用的左右外折方式，屏幕分布在左右两块机壳上，合上手机时屏幕包裹在机壳外部。
(3)例如，型号为Motorola Razr 2019折叠屏手机，采用水滴形上下内折方式，屏幕分布在上下两块机壳上，合上手机时屏幕折在内部。
(4)例如，型号为Samsung Galaxy Z Flip折叠屏手机，采用U形上下内折方式，屏幕分布在上下两块机壳上，合上手机时屏幕折在内部。
以上四种折叠方式都是通过折叠铰链的机械机构实现。然而现有折叠手机的折叠铰链机械结构复杂，组装累计公差大，长时间使用容易磨损，导致精度难以保证。
再一方面，现有折叠手机一般为一整块柔性屏幕构成，所以折叠必须保证两侧同步运动，不能使得两侧的屏幕各自单独运动。
发明内容
为了解决上述技术中折叠铰链机械结构复杂的技术问题，本申请提供了一种不依赖于复杂结构折叠铰链的可折叠屏幕以及折叠屏移动终端。
第一方面，本申请提供了一种可折叠屏幕，包括盖板、两个屏幕以及导光件；所述盖板位于外侧面；两个所述屏幕均包括一个侧向显示部，两个所述侧向显示部均朝向两个所述屏幕之间的导光件设置；所述导光件包括两个反光面，两个所述反光面与两个所述侧向显示部一一对应地设置，以通过各个反光面将相应的侧向显示部的显示画面反射至盖板处，以透过所述盖板向外侧显示。
本申请一实施例中，各所述屏幕呈L形，屏幕的端部处的弯折部形成侧向显示部。
本申请一实施例中，所述侧向显示部与所述屏幕结合部的外侧面为圆导角。
本申请一实施例中，所述圆导角外结合有导光部，所述导光部具有面向所述导光件的侧向出光面，以通过导光件对侧向出光面的现实画面进行反射，从而将所述圆导角外显示画面经所述导光件反射向外。
本申请一实施例中，所述导光部材质为固化的光学胶。
本申请一实施例中，所述侧向出光面结合有定向出光的滤光膜。
本申请一实施例中，所述盖板为聚酰亚胺薄膜或聚酯薄膜。
本申请一实施例中，所述盖板上设置有用于单向向外侧导光的滤光膜，所述滤光膜位于盖板靠近导光件的一侧。
本申请一实施例中，所述滤光膜的两端分别与两侧的所述侧向显示部对齐。
本申请一实施例中，所述导光件的截面呈三角形，两个所述反光面分别位于导光件的两个对称设置的斜面上。
本申请一实施例中，两个所述反光面均相对所述侧向显示部呈45度倾角。
本申请另一方面提供一种折叠屏移动终端，包括如前所述的可折叠屏幕。
本申请实施例提供的上述技术方案与现有技术相比具有如下优点：
本申请实施例的屏幕技术方案中，所述盖板位于外侧面；两个所述屏幕均包括一个侧向显示部，两个所述侧向显示部均面向两个所述屏幕之间的导光件；所述导光件包括两个反光面，两个所述反光面分别对应两个所述侧向显示部，以分别将各所述侧向显示部的显示画面向所述盖板一侧反射，以透过所述盖板向外侧显示。由于利用反光镜的反射输出原理，将左右两侧的屏幕的显示内容向外反射，使屏幕显示内容传递到用户眼中。左右两侧屏幕各自独立存在，可以各自单独折叠展开运动，相互之间相对自由。

具体实施方式
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组合。下面将参考附图并结合实施例来详细说明本申请。
为了解决上述技术中折叠铰链机械结构复杂的技术问题，本申请提供了一种不依赖于复杂结构折叠铰链的可折叠屏幕以及折叠屏移动终端。
本申请实施例的屏幕技术方案中，所述盖板位于外侧面；两个所述屏幕均包括一个侧向显示部，两个所述侧向显示部均面向两个所述屏幕之间的导光件；所述导光件包括两个反光面，两个所述反光面分别对应两个所述侧向显示部，以分别将各所述侧向显示部的显示画面向所述盖板一侧反射，以透过所述盖板向外侧显示。由于利用反光镜的反射输出原理，将左右两侧的屏幕的显示内容向外反射，使屏幕显示内容传递到用户眼中。左右两侧屏幕各自独立存在，可以各自单独折叠展开运动，相互之间相对自由。
应该理解提，本申请主要技术构思在于，以两个或更多个屏幕组成可折叠屏幕，以一个外侧的盖板维护视觉效果，并且，利用分别面向两侧屏幕的导光件来完成屏幕结合部的显示画面输出。所以，应该认为基于以上主要技术构思引伸而来的各种变形或改进，应该属于本申请权利范围所覆盖的情形。
实施例一
图1为本申请实施例提供的一种可折叠屏幕背视结构示意图，图2为本申请实施例提供的一种可折叠屏幕侧视结构示意图，图3为本申请实施例提供的一种可折叠屏幕正视结构示意图，图4为本申请实施例提供的一种可折叠屏幕立体结构示意图，图5为本申请实施例提供的一种可折叠屏幕分解结构示意图，以及图6为图2中A处局部放大结构示意图。
第一方面，本申请提供了一种可折叠屏幕，主要包括盖板1、两个屏幕2以及导光件3。所述盖板1位于面向用户的外侧面，两个所述屏幕2均包括一个侧向显示部21，两个所述侧向显示部21均面向两个所述屏幕2之间的导光件3；所述导光件3包括两个反光面31，两个所述反光面31分别对应两个所述侧向显示部21，以分别将各所述侧向显示部21的显示画面向所述盖板1一侧反射，以透过所述盖板1向外侧显示。反光镜的反光面将水平光线折射到竖直方向，竖直方向的光线透过盖板1，以便于传播到用户眼中。
应该理解的是，具体实施例中一方面两个屏幕2可选择为柔性液晶屏显示模组或OLED屏显示模组；另一方面由于屏幕2并不需要弯折变形，所以也可以选择为硬质基板的液晶屏显示模组或OLED屏显示模组。
本申请实施例中，各所述屏幕2可概呈L形，所述侧向显示部21为所述屏幕2一端的弯折部。所述侧向显示部21与所述屏幕2结合部的外侧面为圆导角。
具体实施例中，所述盖板1可选择为聚酰亚胺薄膜(PolyimideFilm)或聚酯薄膜(BOPET)等透光材料。而盖板1与屏幕2之间可具有OCA光学胶(Optically Clear Adhesive)进行结合。
其中一可选实施例中，所述盖板1还可以一体成形有单向向外侧导光的滤光膜，所述滤光膜位于面向所述导光件3的一侧。以防止除竖直导出的显示画面外，其他方向漫反射光线不会出射，可避免从外界观察到盖板下侧各组件。反光单向透视膜由反光材料、黑白膜、离型层和通孔共同构成。所述滤光膜可选择为晶彩格系列微棱镜结构反光材料。黑白膜为PET材料，两面颜色不一样，一面是白色亮面反光效果好，一面是黑色面，不反光，也可制成黑色反光面，对于光学产品制造遮光效果良好。离型层是热转印常用到的一种材料，底材是PET，经过涂布硅油而成所以也叫硅油膜，产品具有很好的吸附性和贴合性。通孔作用为实现单向透视效果。
更具体地，所述滤光膜11的两端对齐两侧的所述侧向显示部21位置，从而将折叠屏幕的结合部的细节均进行遮蔽。另一方面，也可以将屏幕2圆导角处显示内容，以单向出光方式向外透光显示。
本申请一实施例中，所述导光件3选择为截面呈三角形的棱镜形状，两个所述反光面31位于所述导光件3对称的两个斜面上。两个所述反光面31相对所述侧向显示部21呈45度倾角。以便于将两个侧向显示部21光线竖直反射向外侧，供外部获得显示内容。导光件3可选择固定于屏下壳体。
图7为本申请实施例提供的一种可折叠屏幕折叠状态侧视结构示意图，图8为本申请实施例提供的一种可折叠屏幕折叠状态立体结构示意图，以及图9为图7中B处局部放大结构示意图。
参见图中所示意，由于左右两块屏幕2模组单独设置，左右分开，所以当折叠手机折叠或者展开时，可以单独使得一侧的壳体连同屏幕运动，而另一侧的壳体和屏幕保持静止。
此处说明下，传统的折叠手机其折叠屏幕为一整块柔性屏幕模组，而且允许的折叠区域是固定的，一般设置在中间；所以必须使左右两侧的屏幕同时运动，才能保证柔性屏幕模组在折叠时不受外力。
此实施例配置的柔性屏幕模组、潜望式反光镜与盖板之间可以设置有光学OCA胶,可以使光线透过且不影响显示效果。
相比于传统的机械铰链带动的折叠手机而言，不仅利用反光镜的潜望原理，将左右两侧的柔性屏幕的显示内容反射，使屏幕显示内容传递到用户眼中；而且左右两侧柔性屏幕各自独立存在，可以各自单独折叠展开运动，相互之间相对自由。
实施例二
图10为本申请另一实施例提供的可折叠屏幕展开状态局部放大结构示意图，图11为本申请另一实施例提供的可折叠屏幕折叠状态局部放大结构示意图。
该实施例中，一种可折叠屏幕，主要包括盖板1、两个屏幕2以及导光件3。所述盖板1位于面向用户的外侧面，两个所述屏幕2均包括一个侧向显示部21，两个所述侧向显示部21均面向两个所述屏幕2之间的导光件3；所述导光件3包括两个反光面31，两个所述反光面31分别对应两个所述侧向显示部21，以分别将各所述侧向显示部21的显示画面向所述盖板1一侧反射，以透过所述盖板1向外侧显示。反光镜的反光面将水平光线折射到竖直方向，竖直方向的光线透过盖板1，以便于传播到用户眼中。
各所述屏幕2可概呈L形，所述侧向显示部21为所述屏幕2一端的弯折部。所述侧向显示部21与所述屏幕2结合部的外侧面为圆导角。所述盖板1还可以一体成形有单向向外侧导光的滤光膜11，所述滤光膜11位于面向所述导光件3的一侧。以防止除竖直导出的显示画面外，其他方向漫反射光线不会出射，可避免从外界观察到盖板下侧各组件。反光单向透视膜由反光材料、黑白膜、离型层和通孔共同构成。所述滤光膜可选择为晶彩格系列微棱镜结构反光材料。黑白膜为PET材料，两面颜色不一样，一面是白色亮面反光效果好，一面是黑色面，不反光，也可制成黑色反光面，对于光学产品制造遮光效果良好。离型层是热转印常用到的一种材料，底材是PET，经过涂布硅油而成所以也叫硅油膜，产品具有很好的吸附性和贴合性。通孔作用为实现单向透视效果。
相比前一实施例，以下介绍另一改进实施例的主要区别点在于：
本申请一实施例中，所述圆导角外结合有导光部22，所述导光部22具有面向所述导光件3的侧向出光面23，以将所述圆导角外显示画面经所述导光件3反射向外。其中，所述导光部22材质可选择为固化的光学胶。所述侧向出光面23结合有定向出光的滤光膜24。以便于将圆导角外显示画面定向向导光件3方向出光，以将折叠屏中部画面铺满。所述滤光膜可选择为晶彩格系列微棱镜结构反光材料。黑白膜为PET材料，两面颜色不一样，一面是白色亮面反光效果好，一面是黑色面，不反光，也可制成黑色反光面，对于光学产品制造遮光效果良好。
本实施例中，可将屏幕导圆角区的显示画面更保真的向外反射显示，可以避免横向拉伸的情况。
本申请另一方面提供一种折叠屏移动终端，包括如前所述的可折叠屏幕。
需要注意的是，这里所使用的术语仅是为了描述具体实施方式，而非意图限制根据本申请的示例性实施方式。如在这里所使用的，除非上下文另外明确指出，否则单数形式也意图包括复数形式，此外，还应当理解的是，当在本说明书中使用术语“包含”和/或“包括”时，其指明存在特征、步骤、操作、器件、组件和/或它们的组合。
除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本申请的范围。同时，应当明白，为了便于描述，附图中所示出的各个部分的尺寸并不是按照实际的比例关系绘制的。对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论，但在适当情况下，所述技术、方法和设备应当被视为授权说明书的一部分。在这里示出和讨论的所有示例中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它示例可以具有不同的值。应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
在本申请的描述中，需要理解的是，方位词如“前、后、上、下、左、右”、“横向、竖向、垂直、水平”和“顶、底”等所指示的方位或位置关系通常是基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，在未作相反说明的情况下，这些方位词并不指示和暗示所指的装置或元件必须具有特定的方位或者以特定的方位构造和操作，因此不能理解为对本申请保护范围的限制；方位词“内、外”是指相对于各部件本身的轮廓的内外。
为了便于描述，在这里可以使用空间相对术语，如“在……之上”、“在……上方”、“在……上表面”、“上面的”等，用来描述如在图中所示的一个器件或特征与其他器件或特征的空间位置关系。应当理解的是，空间相对术语旨在包含除了器件在图中所描述的方位之外的在使用或操作中的不同方位。例如，如果附图中的器件被倒置，则描述为“在其他器件或构造上方”或“在其他器件或构造之上”的器件之后将被定位为“在其他器件或构造下方”或“在其他器件或构造之下”。因而，示例性术语“在……上方”可以包括“在……上方”和“在……下方”两种方位。该器件也可以其他不同方式定位(旋转90度或处于其他方位)，并且对这里所使用的空间相对描述作出相应解释。
此外，需要说明的是，使用“第一”、“第二”等词语来限定零部件，仅仅是为了便于对相应零部件进行区别，如没有另行声明，上述词语并没有特殊含义，因此不能理解为对本申请保护范围的限制。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
