背景技术
随着电子科技的快速发展，电子产品行业竞争愈发激烈，用户对手机等电子产品性能和外观的要求也越来越高。为了提高电子产品的便携性，柔性面板成为了目前研究的热点。
以用于手机、平板电脑等需要触控操作的设备为例，除了需要保证良好的触控操作和显示性能，随着对电子产品便携性和操作便利性等需求的进一步提出，还希望电子产品能够具有较佳的柔韧性和可弯折性，因此，柔性功能面板应运而生。以用于实现显示功能的柔性显示面板为例，在使用中能够实现较佳的显示效果的同时，由于设备的柔性能力，还能够使其形成一定的弯折状态和显示角度的改变，不但能够提高使用和操作的便利性，还提高了柔性显示面板的使用寿命，若柔性显示面板同时还需实现触控的功能，即在柔性显示面板中设置柔性触摸传感器，柔性触摸传感器通过感应使用者在柔性功能面板上的触摸操作动作，将触摸信号传送至处理芯片实现功能。
以用于实现显示的柔性功能面板为例，现有技术的结构通常包括柔性基材、电极图案导电层、边缘走线层以及显示模组，对于需要实现触控功能的柔性功能面板，通过在电极图案导电层上形成的电极图案实现触摸感应。
但是现有的柔性功能面板容易在多次弯曲或卷曲操作后出现产品结构的弯曲或卷曲定形，导致柔性功能面板无法恢复原先的平展状态，从而对产品后续的使用效果和外观均会造成不良影响。

现结合附图，对本公开的较佳实施例作详细说明。
本公开实施例的一方面，提供一种柔性功能面板，如图1所示，包括：柔性基底110、设置在柔性基底110上的功能层120及发热层130，发热层130用于在通电状态下发热。
其中，柔性基底110通常采用具有较高可见光透过率的PET(聚对苯二甲酸二乙酯)柔性薄膜，以使本公开的柔性功能面板实现显示功能时，能够提高显示透光率。当然，示例的，在本公开实施例中，柔性基底110还可以采用PI(聚酰亚胺)柔性薄膜或PC(聚碳酸酯)柔性薄膜等，此处对柔性基底110的材质不做具体限制，只要能够呈现柔性可弯折状态即可。
发热层130通常采用具有各种形状的电阻材料，在通电状态下电阻材料能够将电能转化为热能，从而使发热层130能够发热。
本公开实施例提供的一种柔性功能面板，包括柔性基底110以及设置在柔性基底110上的功能层120，通过设置在柔性基底110上的功能层120能够实现特定功能。在柔性基底110上还设置有发热层130，发热层130在通电的状态下能够进行发热。在正常工作时，通过发热层130发热能够对柔性功能面板中的柔性基底110以及柔性基底110上的其他层级进行整体加热，随着柔性基底110的温度逐渐升高，柔性基底110的卷曲定形的状态会 逐渐消失，从而使由于长期使用或长时间弯曲而导致的柔性基底110弯曲变形或卷曲形态得到消除，进而使本公开的柔性功能面板能够减少因长期使用或长时间弯曲而导致弯曲变形或卷曲定形的情况发生。
可选地，发热层130在发热时驱动柔性功能面板恢复平整状态。
通过发热层130在通电状态下产生的热量能够对该柔性功能面板中的柔性基底110以及柔性基底110上的其他层级进行加热，使柔性基底110能够恢复平整，从而使该柔性功能面板整体恢复平整状态。
可选地，如图1所示，发热层130与柔性基底110接触设置。
发热层130位于柔性基底110与功能层120之间。柔性基底110与发热层130直接接触，即在柔性基底110上首先设置发热层130，然后再设置功能层120。由于柔性功能面板在使用和弯折过程中，相较于其他膜层，柔性基底110更易发生变形，也更需要校正，在柔性基底110上首先设置发热层130，能够使得发热层130通电加热产生的热量直接向柔性基底110传导，使得发热层130对柔性基底110的加热效果相对更好，柔性基底110的温度上升更快，消除柔性基底110弯曲变形或卷曲定形的时间相对较短，并且平整效果相对较好。
可选地，如图16所示，发热层130设置在功能层120之上，且与功能层120之间设置有绝缘导热层150。
如图16所示，通过绝缘导热层150使发热层130与功能层120之间绝缘，从而避免功能层120中的电路因与发热层130导通而出现短路等不良现象，从而保证了柔性功能面板的工作稳定性。同时，由于绝缘导热层150自身的导热性能，提高热量的传导能力，尽可能使得整个柔性功能面板的发热和传热均匀，进而提高柔性功能面板消除弯曲变形或卷曲定形的速率和效果。
可选地，发热层130包括导电发热材料，导电发热材料与功能层120的导电材料同层设置。
需要说明的是，发热层130的导电发热材料与功能层120的导电材料层同层设置，且发热层130与功能层120的导电材料层以及功能层120的信号线引线140之间不接触。
示例地，如图9所示，功能层120的导电材料层设置在柔性基底110上，发热层130的导电发热材料绕设在功能层120的信号线引线140的外周并位于柔性基底110的边缘，即柔性功能面板的非功能区域范围内。
示例地，功能层120的导电材料层和发热层130的导电发热材料均设置在柔性基底110上，且导电发热材料与导电材料层均位于柔性功能面板的功能区域范围，导电材料层和导电发热材料之间不接触，即相互不导通。
将发热层130的导电发热材料与功能层120的导电材料层同层设置，发热层130也设置在柔性功能面板的非功能区域且绕设于信号线引线140外周。由于发热层130与功能层120及信号线引线140之间不接触，所以无需再设置位于发热层130与功能层120之间的绝缘导热层150，从而降低柔性功能面板的成本。
可选地，导电发热材料绕设于导电材料层外周。
需要说明的是，导电发热材料绕设于功能层120的导电材料层的的外周，且导电发热材料与功能层120的导电材料层相互不接触。
示例地，如图10、图11所示，导电发热材料设置于功能层120的导电材料层的外周，且导电发热材料位于功能层120的信号线引线140上，在导电发热材料与功能层120的信号线引线140之间设置有用于绝缘导电发热材料与信号线引线140的绝缘导热层150。
可选地，功能层120包括有机发光显示层。
有机电致发光二极管器件(Organic Light Emitting Diode，OLED)作为一种电流型发光器件，因其所具有的自发光、快速响应、宽视角和可用于柔性显示等特点而越来越多地被应用于高性能显示领域当中。示例的，本公开实施例的功能层120包括有机发光显示层，即本公开实施例的柔性功能面板可以为通过有机电致发光的柔性显示面板。
需要说明的是，本公开实施例中所述的有机发光显示层，不限于单一层级，本领域技术人员应当知晓，用于实现有机发光显示的层级通常包括多个层级结构，多个层级结构共同形成能够通电实现发光显示的发光显示层，示例的，发光显示层可以包括设置在柔性基底110和封装结构之间的对应每个子像素位置处的阳极、有机材料功能层、阴极、以及位于相邻两个子像素之间的像素界定层，以通过阳极出射的OLED有机发光显示层为例，通常，阳极采用氧化铟锌、氧化铟锡等透明导电材料制作，以保证出光效率，阴极通常采用金属材料制作，以提高电致发光的工作效率。
可选地，功能层120的导电材料层包括多个功能电极，导电发热材料在第一时间与功能层120的功能电极配合执行预设功能，导电发热材料在第二时间通电发热。
需要说明的是，本公开实施例中对于第一时间和第二时间的发生时间和延续时长不作具体限定，但是根据本申请的前述内容，本领域技术人员应当知晓，导电发热材料在第一时间的工作与在第二时间的工作不会同时发生，即导电发热材料在能够交替进行两种工作状态。导电发热材料在第一时间与功能层120的功能电极配合执行预设功能，即第一时间为柔性功能面板正常使用实现其相应功能的时间。例如，对于用于实现显示功能的柔性显示面板，在第一时间，导电发热材料与功能层120的功能电极共同作用以执行的预设功能即为实现显示。导电发热材料在第二时间通电发热，在第二时间，导电发热材料通电发热既能够为消除柔性功能面板弯曲变形而工作。在第二时间，导电发热材料不作为显示或其 他功能需要使用，而是单独通电以产生热量，实现对柔性功能面板的加热作用，以使本公开实施例的柔性功能面板可以消除弯曲变形或卷曲定形。
将功能层120的导电材料层设置为由多个功能电极组成，将导电发热材料和功能层120的导电材料层同层设置，在第一时间导电发热材料与功能层120的功能电极能够共同作用执行预设功能，在第二时间，导电发热材料能够通电发热。如此设置使柔性功能面板的发热层130和功能层120相互结合，从而节省柔性功能面板的空间占用以减小本公开实施例的柔性功能面板的厚度，并且通过该设置方式使发热层130和功能层120相结合，能够降低本公开实施例的柔性功能面板的制造成本。
以功能电极为触控电极为例，导电发热材料在第一时间与功能层120的功能电极配合执行预设功能包括感应外界对柔性功能面板的触摸而产生触控信号，从而实现柔性功能面板的触控操作功能。
需要说明的是，通常功能层120的功能电极通过信号线引线140进行触控信号的传输。导电发热材料在第一时间与功能层120的功能电极配合执行预设功能时，导电发热材料也需要通过信号线引线140传输触摸信号。在第二时间，导电发热材料通电产生热量，此时导电发热材料通过信号线引线140传输电流以实现通电。由于在第二时间导电发热材料的发热需要形成电流回路，因此通常导电发热材料的一端连接信号线引线140，另一端连接外接走线170，当信号线引线140和外接走线170均导通时，导电发热材料既能能够产生热量。
可选地，导电发热材料包括多个电极，导电发热材料的多个电极与多个触控电极交替排列。
其中，导电发热材料的多个电极与多个触控电极之间互不接触，且触控电极以及导电发热材料的电极的形状和大小相互配合设置。此处对于触控电极以及导电发热材料的电极的形状和大小不做具体限制，只要能够实现感应外界对柔性功能面板的触摸而产生触控信号即可。
示例地，如图13所示，导电发热材料的多个电极的两端均分别与信号线引线140和外接走线170连接。如图12所示，触控电极以及导电发热材料的多个电极均为条状，且相互平行间隔设置，其中触控电极与信号线引线140连接。在第一时间，断开导电发热材料连接的外接走线170，通过触控电极以及导电发热材料的多个电极相互形成电容，从而感应外界对柔性功能面板的触摸并产生触控信号，通过信号线引线140传输触控信号。在第二时间，连通导电发热材料连接的外接走线170，导电发热材料通过信号线引线140以及外接走线170形成回路，从而产生热量以消除柔性功能面板的弯曲变形。当然，在实际应用中，如图15所示，触控电极以及导电发热材料的多个电极还可以设置为相互平行的由直角 三角形组合而成的长方形结构等。
可选地，导电发热材料的热功率大于导电材料层的热功率。
导电发热材料的热功率大于导电材料层的热功率，则在第二时间，导电发热材料便能够产生相对较多的热量，从而提高消除柔性功能面板弯曲变形或卷曲定形的速率。并且，导电材料层的热功率低于导电发热材料的热功率，能够提高本公开实施例的柔性功能面板的触摸感应的灵敏度，提高用户使用体验。
可选地，柔性功能面板包括功能区域以及围绕功能区域的非功能区域，发热层130位于非功能区域。
其中，位于非功能区域的发热层130，在实际应用中可以根据具体情况设置为多种不同的发热图案。
示例地，如图2和图3所示，发热层130的发热图案可以设置为面层发热图案，即整个发热图案为完整的面层，不存在镂空部分。当然，在本公开实施例中，发热图案还可以是由线形回路构成的发热图案等。例如，线形回路为单道、双道或多道的直线回路，当然在实际应用中，线形回路也可以是曲线回路等其他线形回路。此处对于发热图案为面层结构还是线形回路等其他形状不做限制，以及当发热图案为线形回路时，此处对于线形回路为直线回路还是曲线回路等其他线形回路也不做限制。
示例地，如图4所示，发热层130位于非功能区域中的部分区域，且发热层130为两个互不相连的条形结构，且每个条形结构形成直线回路。
上述示例只是本公开实施例中提出的几种可行方式，在实际应用中，设置于非功能区域的发热层130还可以是其他设置方式，此处不做限制，只要发热层130能够为柔性功能面板提供有效加热即可。
将发热层130设置在非功能区域，能够避免发热层130的发热图案对功能区域的功能层120正常使用造成影响。而且，随着发热层130通电产生的热量由边缘向中间传导，同样能够对功能区域的功能层120进行加热以消除弯曲应力而校正弯曲状态。
可选地，发热层130在非功能区域的形状包括首尾连接的闭合环形、相对两侧分别设置的条形和相邻三侧连接设置的折线形的至少一种。
示例的，如图2和图5所示，以用于平板电脑的显示面板为例，功能区域为矩形，相应的，围绕功能区域的非功能区域为矩形环状。发热层130呈“U”形设置于非功能区域内，即相邻三侧连接设置的折线形，只要位于矩形环状的任意三个相互邻接的侧面即可。又例如，发热层130还可以是由两个“L”形直线回路发热图案组成，或者，发热层130设置在矩形环状的非功能区域内的相对两侧，或者，发热层130沿矩形环状的四边分别设置。
发热层130在非功能区域首尾连接呈闭合环状，能够使发热层130从柔性基底110边 缘的各个位置均匀的将热量传递到柔性基底110上，从而使柔性基底110能够均匀受热，加快对柔性基底110弯曲变形或卷曲定形的消除。又比如，可在功能区域的相对两侧分别设置的条形结构，对应设置于非功能区域内，且发热层130形成的发热图案为直线回路。或者，发热层130还可以为在功能区域的相邻三侧连接设置的折线形结构，对应设置在非功能区域内。
可选地，有机发光显示层在柔性基底110上包括显示区域以及围绕显示区域的非显示区域，如图12和15所示，发热层130包括设置在显示区域的导电发热图案，导电发热图案为透明材质。
需要说明的是，发热层130包括设置在显示区域的导电发热图案，即发热层130完全覆盖在柔性基底110上，位于显示区域的发热层130为导电发热图案，且该导电发热图案为透明材质。
发热层130包括设置在显示区域的导电发热图案，且导电发热图案为透明材料，从而使发热层130能够为柔性基底110分别位于显示区域和非显示区域的部分同时加热，提高发热层130对柔性基底110的加热速率，而且，透明材质的导电发热图案不会对显示面板显示区域的显示造成影响，保证了显示面板的显示效果。
可选地，导电发热图案包括覆盖显示区域的面层图案、排列设置的直线回路图案和排列设置的曲线回路图案的至少一种。
示例地，设置在显示区域的导电发热图案为覆盖显示区域的面层图案。使柔性基底110位于显示区域的部分能够被导电发热图案完全均匀的覆盖并加热(附图未示出)。
可选地，如图13所示，发热层130通过外接走线170通电。如图14所示，外接走线170在非显示区域与有机发光显示层的信号线引线140通过绝缘导热层150隔离。
将外接走线170设置在非显示区域使外接走线170不会对该柔性功能面板的正常工作产生影响。通过绝缘导热层150对外接走线170和信号线引线140进行隔离，能够避免由于外接走线170和信号线引线140之间导通而出现短路等不良情况发生。
可选地，如图8所示，在发热层130上还设置有绝缘导热层160，绝缘导热层160覆盖发热层130。
需要说明的是，绝缘导热层160以及绝缘导热层150均可以采用导热性能相对较好的氧化硅、氮化硅等材料涂层。
示例地，将发热层130设置在功能层120之上，绝缘导热层160覆盖发热层130。当然，在本公开实施例中，发热层130还可以是设置在柔性基底110或者柔性基底110之上的其他膜层结构等设置位置，此处不做具体限制。
通过设置覆盖发热层130的绝缘导热层160，使发热层130产生的热量能够被绝缘导热 层160更均匀的分布在柔性功能面板中，从而提高通过加热消除柔性功能面板弯曲变形或卷曲定形的速率。
可选地，如图6和图7所示，发热层130通过粘接层180与相邻层级粘结。
需要说明的是，发热层130通过粘接层180粘结的相邻层级，通常为柔性功能面板包括多个功能层120时，与发热层130连接的另一功能层120或柔性基底110等层级结构。
本公开实施例的另一方面，提供一种柔性装置，包括上述任意一项的柔性功能面板。
需要说明的是，该柔性装置中设置的柔性功能面板具有与前述实施例中的柔性功能面板相同的有益效果。由于前述实施例中，已经对柔性功能面板的结构进行了详细的说明，在此不再赘述。
需要说明的是，在本公开实施例中，柔性装置例如应用于柔性显示功能，至少可以包括有机发光二极管显示装置，例如该柔性装置可以为柔性显示器、柔性数码相框、柔性手机或柔性平板电脑等任何具有柔性显示功能的产品或者部件。
本公开实施例提供的一种柔性装置，该柔性装置采用上述的柔性功能面板，能够减少因长期使用或长时间弯曲而导致弯曲变形或卷曲定形的情况发生。
以上所述仅为本公开的优选实施例而已，并不用于限制本公开，对于本领域的技术人员来说，本公开可以有各种更改和变化。凡在本公开的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
综上所述，本公开提供了一种柔性功能面板及柔性装置，在柔性基底110上设置有用于实现对应功能的功能层120，还设置有发热层130，该发热层130在通电的状态下能够进行发热。通过发热层130发热能够对柔性功能面板进行加热，柔性基底110的弯曲变形或卷曲定形会由于热量上升而逐渐消失，从而使由于长期使用或长时间弯曲而导致的柔性基底110弯曲变形或卷曲定形得到消除，使该柔性功能面板能够减少因长期使用或长时间弯曲而导致弯曲变形或卷曲定形的情况发生，可在显示技术、触控技术等领域广泛应用。
