Description

终端设备及其折叠显示屏 技术领域
本申请涉及终端设备技术领域，特别是涉及终端设备及其折叠显示屏。
背景技术
对于手机和平板电脑等终端设备而言，显示屏作为提供的显示或交互的重要部件，对提升用户体验起到至关重要的作用。折叠显示屏作为一种新形态的发展趋势，不仅可以提高便捷性，展开后也能够充分享受大屏手机的优势，所以各大厂商竞相发布折叠显示屏。
折叠显示屏分为内折和外折两种模式，其中，内折是指折叠显示屏的显示面相向折拢，该内折方式下，折叠后，显示屏的显示面彼此相对的叠设在一起；外折是指折叠显示屏的显示面背向折拢，该外折方式下，折叠后，显示屏的显示面彼此相背。
由于折叠显示屏具有一定厚度，无论内折结构的折叠显示屏，还是外折结构的折叠显示屏，在折叠过程中，折叠显示屏的相背两侧受到拉力或压应力，容易导致折叠显示屏的表面形成折痕，产生的折痕会随着弯折次数的增加而变得更加明显，严重影响折叠显示屏使用寿命，以及显示画面的整体感。

作为在此使用的“终端设备”指包括但不限于经由以下任意一种或者数种连接方式连接的能够接收和/或发送通信信号的装置：
(1)经由有线线路连接方式，如经由公共交换电话网络(Public Switched Telephone Networks，PSTN)、数字用户线路(Digital Subscriber Line，DSL)、数字电缆、直接电缆连接；

(4)常规膝上型和/或掌上型接收器；
(5)常规膝上型和/或掌上型无线电电话收发器等。
本申请一实施例提供的一种终端设备，可以是折叠式手机或折叠式平板电脑。该终端设备包括能够适应折叠使用需要的折叠显示屏。
结合图1和图2所示，折叠显示屏包括柔性显示面板10和可变轴折叠组件20。为了 便于理解，将柔性显示面板10折叠过程中，绕可变轴折叠组件20的转折处所对应的轴线定义为“折叠轴线”，也就是说，可变轴折叠组件20具有折叠轴线，柔性显示面板10折叠过程中，柔性显示面板10绕折叠轴线折转运动。以现有的折叠显示屏为例，折叠显示屏的转轴结构的轴线即为“折叠轴线”。需要特别说明的是，本申请的折叠显示屏中，折叠轴线在可变轴折叠组件20中的位置是可以调整的。确切的说，对于可变轴折叠组件20而言，可变轴折叠组件20的折叠轴线是不固定的，通过折叠轴线位置的变化，使得柔性显示面板10以折叠轴线为转动中心进行折转运动时，尽可能减少柔性显示面板10在同一位置折转而容易产生折痕，以提高柔性显示面板10的使用寿命。
具体地，在一实施例中，柔性显示面板10具有显示面10a，显示面10a指的是柔性显示面板10进行显示时出光显示画面的一侧表面。
可变轴折叠组件20设置于柔性显示面板10的背向显示面10a的一侧，该可变轴折叠组件20作为转动结构，为柔性显示面板10折转运动提供转动支撑，确切的说，可变轴折叠组件20的折叠轴线作为柔性显示面板10折转运动的转动轴。
在一些实施例中，结合图1、图2和图5所示，可变轴折叠组件20包括轴体21以及设于轴体21两端的磁线圈22，轴体21包括柔性外层211以及由柔性外层211包覆的多个磁珠212，柔性外层211与柔性显示面板10相连接，磁线圈22通电时，多个磁珠212在磁线圈22的磁场下移动。由于挤压柔性外层211是柔性可变形的，因此，柔性外层211不会限制磁珠212的移动，使得磁珠212在磁线圈22的磁场作用下排布。确切的说，当通入磁线圈22的电流发生改变时，磁线圈22的磁场将发生变化，也即磁线圈22产生可变磁场，调整多个磁珠212的排布，从而在当可变轴折叠组件20折转运动时，不同排列方式下的磁珠212将会产生不同的折弯位置，也即可变轴折叠组件20的折叠位置不同，从而减少柔性显示面板10在同一位置反复折叠而形成折痕的机率。
结合图2所示，柔性显示面板10包括第一面板101、第二面板102以及柔性连接部103。柔性连接部103可弯折地连接于第一面板101和第二面板102之间，从而第一面板101和第二面板102能够相对折转运动，柔性连接部103能够适应这种弯折的需要。
该实施例中，可变轴折叠组件20与柔性连接部103的背向显示面10a的一侧相连接，且当柔性显示面板10折叠运动时，可变轴折叠组件20对应折叠轴线的部分能够抵持柔性 连接部103，以使得柔性连接部103绕折叠轴线折转运动。由于柔性显示面板10折转运动时，第一面板101和第二面板102之间的柔性连接部103将发生弯折，以适应第一面板101和第二面板102的合拢和展开需要。
柔性连接部103作为柔性显示面板10的折弯位置，继而柔性连接部103是柔性显示面板10的最容易出现折痕的部位，该实施例中，可变轴折叠组件20对应折叠轴线的部分与柔性连接部103相抵持，从而在柔性连接部103折转时，柔性连接部103将沿折叠轴线折转。由于可变轴折叠组件20中，可以通过改变通入磁线圈22的电流，以调整磁场而使得多个磁珠212的排布发生变化，继而改变可变轴折叠组件20易折叠的位置，也即调整折叠轴线的位置，这样柔性连接部103的折转位置将可以通过改变磁线圈22的电流而发生改变，进而尽可能减少柔性连接部103在同一位置折转，以降低折痕出现机率。
为了便于理解，下面仅以举例的形式对柔性连接部103的折叠位置不固定加以说明，并不对本申请的柔性显示屏的使用状态进行限定。
例如，参阅图3所示，在一种使用场景中，柔性显示面板10沿可变轴折叠组件20的折叠轴线折叠后，第一面板101和第二面板102重合在一起。结合图4所示，在柔性显示面板10沿折叠轴线折叠后，第一面板101和第二面板102可以是错开的，也就是说，柔性显示面板10的折叠位置将与图3示出的折叠位置不同，继而达到减少同一位置反复折叠而形成折痕的机率。
需要说明的是，由于磁珠212的排布受磁线圈22的磁场影响，也即是说，磁线圈22的磁场变化，将驱使磁珠212运动而呈现不同排列。
例如，参阅图5所示，磁珠212在线性磁场下，将呈现出规律性的线性排列，也即，多个磁珠212呈多层排布，且每一层的磁珠212呈直线排布。
再例如，参阅图6所示，通过改变磁线圈22的电流，使得磁线圈22产生非线性磁场，从而使得磁珠212在磁场的作用下呈现非线性排列，继而磁珠212对柔性外层211产生不同程度的挤压，使得轴体21呈现扭曲，这样，在可变轴折叠组件20进行折叠时，由于扭曲的轴体21内的磁珠212是非线性排布的，在折转时，不会在同一个位置进行折转，继而柔性显示面板10以可变轴折叠组件20的折叠轴线为转动中心进行折转运动时，柔性显示面板10的折转位置是变化的，继而减少同一位置反复折转而产生折痕的机率。
当通入磁线圈22的电流发生改变时，磁线圈22能够产生可变磁场，以调整多个磁珠212在柔性外层211内的排布。
在一些实施例中，当通入磁线圈22的电流方向发生改变时，磁线圈22能够产生可变磁场，以调整多个磁珠212在柔性外层211内的排布。
在一些实施例中，当通入磁线圈22的电流大小发生改变时，磁线圈22能够产生可变磁场，以调整多个磁珠212在柔性外层211内的排布。
无论是改变磁线圈22的电流方向，还是改变磁线圈22的电流大小，都能引起磁线圈22的磁场变化，从而磁珠212在这种变化的磁场下呈现不同的排列，这样可变轴折叠组件20便能够具有位置可调节的折叠轴线，减少柔性显示面板10在同一位置反复折转而形成折痕的机率。
需要说明的是，磁线圈22的在轴体21两端可以采取多种排布方式，只需要改变磁线圈22的电流，能够调整磁场，以使得磁珠212呈不同排列即可。
在一些实施例中，轴体21的两端设有至少两组对应设置的磁线圈22，磁线圈22分别均匀地排布于轴体21的两端。这样改变对应的磁线圈22的电流，可以使得位于该对应的磁线圈22之间的磁珠212沿磁场进行排布的方式。
在另一些实施例中，轴体21的两端设有至少两组对应设置的磁线圈22，且各组磁线圈22所产生的磁场彼此交叠。利用这种交叠的磁场，使得磁珠212在柔性外层211内排布更为随机，这样，可变轴折叠组件20的折叠轴线的变化更灵活，减少柔性显示面板10沿同一位置进行折转的机率，以减少折痕的出现。
结合图7所示，在一些实施例中，位于轴体21的同一端的磁线圈22呈波浪状排布。具体地，位于轴体21的同一端的磁线圈22中，相邻的磁线圈22呈“V”字形设置。对于磁线圈22的排布方式，在此不做赘述。
在一些实施例中，柔性外层211内填充有润滑剂，润滑剂充盈在磁珠212的间隙中，起到较好的润滑效果，以利于磁珠212之间彼此运动，从而使得可变轴折叠组件20更顺畅进行折转。
润滑剂可以是硬脂酸镁、淀粉、硬脂酸钙、硬脂酸铝和硬脂酸等固体润滑剂。在另一些实施例中，润滑剂可以是西甲硅油、卵磷脂、植物油或矿物油等固体润滑剂。
在一些实施例中，柔性外层211的材料选自聚醚砜(Polyether sulfones，PES)、聚丙烯酸酯(Polyacrylate，PAR)、聚醚酰亚胺(Polyetherimide，PEI)、聚萘二甲酸乙二醇酯(Polyethylene naphthalate；，PEN)、聚对苯二甲酸乙二醇酯(Polyethylene terephthalate，PET)、聚苯硫醚(Polyphenylene Sulfide，PPS)、聚烯丙基酯(Polyallylate)、聚酰亚胺(Polyimide，PI)、聚碳酸酯(Polycarbonate，PC)或乙酸丙酸纤维素(Cellulose acetate propionate，CAP)中的一种或多种。采用这种材质的柔性外层211的柔性或可弯曲性较好，继而减少对磁珠212相对移动时的束缚，以使得可变轴折叠组件20能够灵活折转。
需要说明的是，柔性显示面板10的结构具有多种形式。
例如，如图8所示，图8为本申请实施例提供的一种柔性显示面板10的层结构示意图。图8示出的柔性显示面板10，包括依次层叠设置的基板11、有机发光二极管(Organic Light-Emitting Diode，OLED)层12、薄膜封装(Thin Film Encapsulation，TFE)层13。
再如图9所示，图9为本申请实施例提供的另一种柔性显示面板10的层结构示意图。图9示出的柔性显示面板10，包括基板11、薄膜晶体管(Thin Film Transistor，TFT)层12、有机发光二极管(Organic Light-Emitting Diode，OLED)层13、薄膜封装(Thin Film Encapsulation，TFE)层14、触控层15以及偏光片16。
其中，薄膜晶体管层12、有机发光二极管层13、薄膜封装层14、触控层15和偏光片16依次层叠至基板11的一侧，即，薄膜晶体管层12设置在基板11的一侧，有机发光二极管层13设置在薄膜晶体管层12上，薄膜封装层14设置在有机发光二极管层13上，触控层15设置在薄膜封装层14上，偏光片16设置在触控层15上。
需要说明的是，柔性显示面板10的层结构不限于上述例举的两种结构形式，在满足折叠显示需要的情况下，柔性显示面板10还可以采用其他层结构形式。
参考图10，图10为本申请实施例提供的终端设备100的结构示意图。该终端设备100可以包括射频(RF，Radio Frequency)电路501、包括有一个或一个以上计算机可读存储介质的存储器502、输入单元503、显示单元504、传感器505、音频电路506、无线保真(WiFi，Wireless Fidelity)模块507、包括有一个或者一个以上处理核心的处理器508、以及电源509等部件。本领域技术人员可以理解，图10中示出的终端设备100结构并不构成对终端设备100的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或 者不同的部件布置。

存储器502可用于存储应用程序和数据。存储器502存储的应用程序中包含有可执行代码。应用程序可以组成各种功能模块。处理器508通过运行存储在存储器502的应用程序，从而执行各种功能应用以及数据处理。存储器502可主要包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需的应用程序(比如声音播放功能、图像播放功能等)等；存储数据区可存储根据终端设备100的使用所创建的数据(比如音频数据、电话本等)等。此外，存储器502可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件、闪存器件、或其他易失性固态存储器件。相应地，存储器502还可以包括存储器控制器，以提供处理器508和输入单元503对存储器502的访问。

进一步的，触敏表面可覆盖显示面板，当触敏表面检测到在其上或附近的触摸操作后，传送给处理器508以确定触摸事件的类型，随后处理器508根据触摸事件的类型在显示面板上提供相应的视觉输出。
虽然在图10中，触敏表面与显示面板是作为两个独立的部件来实现输入和输入功能，但是在某些实施例中，可以将触敏表面与显示面板集成而实现输入和输出功能。可以理解的是，显示屏110可以包括输入单元503和显示单元504。
终端设备100还可包括至少一种传感器505，比如光传感器、运动传感器以及其他传感器。具体地，光传感器可包括环境光传感器及接近传感器，其中，环境光传感器可根据环境光线的明暗来调节显示面板的亮度，接近传感器可在终端设备100移动到耳边时，关闭显示面板和/或背光。作为运动传感器的一种，重力加速度传感器可检测各个方向上(一般为三轴)加速度的大小，静止时可检测出重力的大小及方向，可用于识别手机姿态的应用(比如横竖屏切换、相关游戏、磁力计姿态校准)、振动识别相关功能(比如计步器、敲击)等；至于终端设备100还可配置的陀螺仪、气压计、湿度计、温度计、红外线传感器等其他传感器，在此不再赘述。
音频电路506可通过扬声器、传声器提供用户与终端设备100之间的音频接口。音频电路506可将接收到的音频数据转换成电信号，传输到扬声器，由扬声器转换为声音信号输出；另一方面，传声器将收集的声音信号转换为电信号，由音频电路506接收后转换为音频数据，再将音频数据输出处理器508处理后，经射频电路501以发送给比如另一终端设备100，或者将音频数据输出至存储器502以便进一步处理。音频电路506还可能包括 耳机座，以提供外设耳机与终端设备100的通信。
无线保真(WiFi)属于短距离无线传输技术，终端设备100通过无线保真模块507可以帮助用户收发电子邮件、浏览网页和访问流式媒体等，它为用户提供了无线的宽带互联网访问。虽然图10示出了无线保真模块507，但是可以理解的是，其并不属于终端设备100的必须构成，完全可以根据需要在不改变发明的本质的范围内而省略。
处理器508是终端设备100的控制中心，利用各种接口和线路连接整个终端设备100的各个部分，通过运行或执行存储在存储器502内的应用程序，以及调用存储在存储器502内的数据，执行终端设备100的各种功能和处理数据，从而对终端设备100进行整体监控。可选的，处理器508可包括一个或多个处理核心；优选的，处理器508可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器508中。
终端设备100还包括给各个部件供电的电源509。优选的，电源509可以通过电源管理系统与处理器508逻辑相连，从而通过电源管理系统实现管理充电、放电、以及功耗管理等功能。电源509还可以包括一个或一个以上的直流或交流电源、再充电系统、电源故障检测电路、电源转换器或者逆变器、电源状态指示器等任意组件。
尽管图10中未示出，终端设备100还可以包括蓝牙模块等，在此不再赘述。具体实施时，以上各个模块可以作为独立的实体来实现，也可以进行任意组合，作为同一或若干个实体来实现，以上各个模块的具体实施可参见前面的方法实施例，在此不再赘述。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
