本发明涉及柔性显示屏技术领域，尤其涉及一种柔性显示屏、柔性显示屏的弯折检测方法及装置。
背景技术
目前电子设备上常用的交互方式为触摸、点按式交互，而随着近年来柔性显示屏的兴起，带来了很多新的手势操作的可能性，手势的交互方式也更直觉化和易用。现有的柔性显示屏大多使用柔性OLED技术，具有可弯曲、可扭转、可折叠的特性，使得高分辨率、大尺寸的区域与设备的便携性不再成为矛盾，并且其耐用程度也大大高于以往屏幕，从而降低设备意外损坏的概率。
柔性显示设备由于可以产生更多的弯折，形变非常灵活，相比于现有的设备可以引申出更多的手势交互方式，例如弯折缩放、弯折翻页等操作，而这些操作都需要能够在柔性显示设备中准确检测出柔性显示屏的弯折位置，现有技术中对于柔性显示屏弯折位置的检测方法不够精确，不能准确地确定柔性显示屏的弯折位置。
发明内容
基于此，本发明提出了一种柔性显示屏，可以在柔性显示屏中精确地检测到弯折的位置。
一种柔性显示屏，其特征在于，所述柔性显示屏包括第一膜层和第二膜层；
所述第一膜层的第一表面上布有矩阵排列的触点；

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。
需要说明的是，在本发明实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本发明。在本发明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。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
本发明提出了一种柔性显示屏，可以在柔性显示屏中精确地检测到弯折的位置。参照图1及图2，该柔性显示屏包括第一膜层102和第二膜层104，第一膜层102的第一表面布有矩阵排列的触点1022，第二膜层104的第一表面布有矩阵排列的电阻片1042，电阻片1042的电阻值从中心向外边缘单调性变化，如图3所示，在本实施例中，电阻值从中心向边缘呈阶梯状变化；在其他的实施例中，还可以是按照一定的分布公式得到电阻值与半径大小的关系。且第一膜层102的第一表面和第二膜层104的第一表面贴合。且第一膜层102上的触点1022与第二膜层104上的电阻片1042一一对应，每一个触点1022与对应的电阻片1042形成一个检测点106。检测点106连接处理器12，并将通过的电信号传递给处理器12，处理器12用于检测通过各个检测点的电信号的强度，根据电信号的强度变化确定柔性显示屏的弯折位置。
需要说明的是，在本实施例中，第一膜层102的第一表面和第二膜层104的第一表面贴合时，并不是紧密贴合，两个膜层的贴合仍能使得第一膜层102上的触点1022与第二膜层104上的电阻片1042在柔性显示屏弯折时有一定的活动空间，从而由于电阻片上不同区域的阻值大小不同获取的电信号强度不同来判断柔性显示屏的弯折区域。
在本实施例中，处理器检测各个检测点的电信号强度可以是直接获取各个检测点的电信号强度，根据电信号的值判断柔性显示屏是否发生弯折。
在另一个实施例中，处理器可通过编码电路与各个检测点连接，各个检测点的电信号经过编码之后转化为数字信号，处理器根据获取的数字信号解析对应发生变化的检测点的位置，及该位置对应的电流强度的抽样量化的编码值，从而判断柔性显示屏是否发生弯折。
在本实施例中，柔性显示屏展开时，第一膜层上的触点与对应的电阻片的 中心接触，所有的检测点获取的电信号的强度相同。当柔性显示屏发生弯折时，如图4所示，弯折区域上各个检测点处的触点与电阻片的接触位置会发生偏移，如图5所示。由于电阻片的电阻值从中心向外边缘单调性变化，弯折区域上各个检测点通过的电信号会发生变化，如图6中所示，在弯折时电信号相同的点形成一条直线，弯折区域中不同的直线上的检测点的电信号的大小不同，其中A、B、C、D、E表示电信号强度大小相同的检测点所在的直线。
在一个实施例中，电阻片的电阻值从中心向外边缘逐渐增大，触点与电阻片的接触点偏移越大，检测点上通过的电信号的强度越小，故可以通过检测各个检测点上通过的电信号的强度，找到电信号强度发生变化的目标检测点，根据电信号强度相对于初始电信号强度发生变化的检测点所在的区域作为柔性显示屏的弯折区域。
在另一个实施例中，在柔性显示屏第一次弯折时，所检测到的电信号强度为第一强度，当柔性显示屏基于第一次弯折继续进行弯折时，此时检测电信号强度相对于第一强度的大小变化超过阈值的检测点即为目标检测点。在本实施例中，“第一”、“第二”仅用于先后顺序的举例，实际的弯折次数不限于本发明实施例列举的数目。
在其他的实施例中，电阻片的电阻值还可以是从中心向外边缘逐渐减小。
在本实施例中，具体的，可先获取各个检测点的电信号强度，根据电信号强度以及检测点的排列顺序得到电信号强度的分布曲线，根据曲线的变化趋势判断是否发生弯折。例如，附图7和附图8中，曲线所示为不同触点位置电信号强度随电阻值大小的变化，对应的弯折情况如图中所示。其中，附图7中的A到B段的电信号强度保持恒定，表示在直线A和直线B上的检测点处的电信号强度未发生变化，柔性显示屏未发生弯折；B到D段的电信号强度逐渐减小，表示在直线B、C、D上的检测点处发生弯折，且检测点上的触点偏离电阻片中心的偏移量越大，即弯折程度越大；D到E段的电信号强度又保持不变，表示D和E上的检测点处没有发生弯折。
而对于附图8，A到B段的电信号强度保持恒定，表示在直线A和直线B上的检测点处的电信号强度未发生变化，柔性显示屏未发生弯折；B到E段的电信号强度逐渐减小，表示在直线B、C、D、E上的检测点处发生弯折，且 检测点上的触点偏离电阻片中心的偏移量越大，即弯折程度越大。
在一个实施例中，柔性显示屏上设置有固定区域或固定点，如图9所示，可以保持第一膜层和第二膜层在柔性显示屏展开时各个检测点上的触点与电阻片的中心接触。
在一个实施例中，如图10所示，第一膜层与第二膜层之间通过粘合物108贴合，粘合物分布在检测点之间的空隙中，具有较大的形变空间，在柔性显示屏发生弯折时，粘合物发生形变给触点与电阻片的相对移动提供空间，当柔性显示屏恢复平展状态时，粘合物也恢复原形态保证柔性显示屏的第一膜层的触点与第二膜层的电阻片中心准确对位。
在本实施例中，柔性显示屏的显示层与第一膜层和第二膜层之间可以是相互独立的，例如，第一膜层与第二膜层贴合之后，作为整体再与显示层贴合。另一方面，还可以将第一膜层或者第二膜层作为柔性显示屏的显示层，即直接在显示层上设置触点或者电阻片进行检测。
在一个实施例中，如图11所示，第一膜层和第二膜层非贴合面上设置有磁性物质110，第一膜层和第二膜层通过磁性物质110吸附贴合，保证第一膜层和第二膜层处于贴合状态。
在一个实施例中，磁性物质涂覆在第一膜层和第二膜层的非贴合面上，使得柔性显示屏在平展时，第一膜层的触点与第二膜层的电阻片中心准确对位；而当柔性显示屏在发生弯折时，磁性物质仍能提供一定的空间使得触点与电阻片之间能发生移动。
在另一个实施例中，磁性物质还可以是分布在柔性显示屏的部分区域，如边缘位置、中心区域等，使得柔性显示屏在平展时，第一膜层的触点与第二膜层的电阻片中心准确对位；而当柔性显示屏在发生弯折时，磁性物质仍能提供一定的空间使得触点与电阻片之间能发生移动。
在本实施例中，柔性显示屏的显示层与第一膜层和第二膜层之间可以是相互独立的，例如，第一膜层与第二膜层贴合之后，作为整体再与显示层贴合。
在一个实施例中，第二膜层上的电阻片为圆盘形，电阻片的圆心与所述第一膜层上的触点接触。需要说明的是，在其他的实施例中，电阻片的形状还可以有其他的情况，例如椭圆形、多边形等，不限于本发明实施例提供的示例， 但优选的，采用圆盘形的电阻片并设置电阻值渐变时，柔性显示屏从各个方向进行弯折的过程中，触点可以接触到的各个方向的长度都相同，都可以检测到电信号，其效果最好。
此外，本发明提出了一种柔性显示屏的弯折检测方法，可以在柔性显示屏中精确地检测到弯折的位置。参照附图12，本方法的执行包括以下步骤：
步骤S102：接收柔性显示屏上的检测点产生的电信号。
在本实施例中，柔性显示屏展开时，第一膜层上的触点与对应的电阻片的中心接触，所有的检测点获取的电信号的强度相同。
步骤S104：获取电信号的强度发生变化的目标检测点。
当柔性显示屏发生弯折时，如图4所示，弯折位置上各个检测点处的触点与电阻片的接触位置会发生偏移，如图5所示。由于电阻片的电阻值从中心向外边缘单调性变化，弯折位置上各个检测点通过的电信号会发生变化，电信号强度发生变化的检测点即为目标检测点。
在本实施例中，处理器检测各个检测点的电信号强度可以是直接获取各个检测点的电信号强度，根据电信号的值获取目标检测点。
在另一个实施例中，处理器可通过编码电路与各个检测点连接，各个检测点的电信号经过编码之后转化为数字信号，处理器根据获取的数字信号解析对应发生变化的检测点的位置，从而获取目标检测点。
步骤S106：获取目标检测点的位置，根据目标检测点的位置确定柔性显示屏的弯折区域。
如图6中所示，在弯折时电信号相同的点形成一条直线，弯折位置附近不同的直线上的检测点的电信号的大小不同，其中A、B、C、D、E表示电信号强度大小相同的检测点所在的直线。
在一个实施例中，电阻片的电阻值从中心向外边缘逐渐增大，触点与电阻片的接触点偏移越大，检测点上通过的电信号的强度越小，故可以通过检测各个检测点上通过的电信号的强度，找到电信号强度发生变化的目标检测点，根据电信号强度相对于初始电信号强度发生变化的检测点的连线作为柔性显示屏的弯折区域。
在其他的实施例中，电阻片的电阻值还可以是从中心向外边缘逐渐减小。
在本实施例中，具体的，可先获取各个检测点的电信号强度，根据电信号强度以及检测点的排列顺序得到电信号强度的分布曲线，根据曲线的变化趋势判断是否发生弯折。例如，附图7和附图8中，曲线所示为不同触点位置电信号强度随电阻值大小的变化，对应的弯折情况如图中所示。其中，附图7中的A到B段的电信号强度保持恒定，表示在直线A和直线B上的检测点处的电信号强度未发生变化，柔性显示屏未发生弯折；B到D段的电信号强度逐渐减小，表示在直线B、C、D上的检测点处发生弯折，且检测点上的触点偏离电阻片中心的偏移量越大，即弯折程度越大；D到E段的电信号强度又保持不变，表示D和E上的检测点处没有发生弯折。
而对于附图8，A到B段的电信号强度保持恒定，表示在直线A和直线B上的检测点处的电信号强度未发生变化，柔性显示屏未发生弯折；B到E段的电信号强度逐渐减小，表示在直线B、C、D、E上的检测点处发生弯折，且检测点上的触点偏离电阻片中心的偏移量越大，即弯折程度越大。
在一个实施例中，获取电信号的强度相对于初始强度的变化大于阈值的目标检测点，其中初始强度为柔性显示屏完全展开时检测到的检测点的电信号的强度。
例如，在柔性显示屏完全展开时，各个检测点通过的电信号强度相同，假设均以电流大小表示，为10毫安；变化的阈值设置为2毫安。在柔性显示屏弯折时，按照附图6中的示例，检测到的A上的检测点的电信号大小为10毫安，B上的检测点的电信号大小为7.5毫安，C上的检测点的电信号大小为5毫安，其中，B、C上的检测点的电信号强度的变化均超过了设定的阈值，从而可以判断出弯折区域在B、C直线上。通过设定合适的阈值，可以排除误操作产生的微小弯折，避免处理器误判断引起电量损耗。
在另一个实施例中，在柔性显示屏第一次弯折时，所检测到的电信号强度为第一强度，当柔性显示屏基于第一次弯折继续进行弯折时，此时检测电信号强度相对于第一强度的大小变化超过阈值的检测点即为目标检测点。在本实施例中，“第一”、“第二”仅用于先后顺序的举例，实际的弯折次数不限于本发明实施例列举的数目。
例如，在柔性显示屏第一次弯折时，变化的阈值设置为2毫安，按照附图6中的示例，检测到的A上的检测点的电信号大小为10毫安，B上的检测点的电信号大小为7.5毫安，C上的检测点的电信号大小为5毫安；在第二次检测时，A上的检测点的电信号大小为7.5毫安，B上的检测点的电信号大小为5毫安，C上的检测点的电信号大小为5毫安，那么，对比第一次检测的电信号的值可知，第二次弯折区域为直线A和B上检测点所在的区域。
在一个实施例中，根据柔性显示屏的弯折区域获取柔性显示屏的显示区域，在显示区域上展示相应的内容。例如附图13和附图14中所示，在检测到柔性显示屏的弯折区域之后，判断弯折后的部分区域以外的显示屏上的区域为显示区域，并在显示区域上显示相应的内容。具体的，以图6为例，在检测到弯折区域为直线B及其右上区域时，直线A及其左侧区域的检测点的电信号强度没有发生变化，故判定直线A及其左侧区域为显示区域。
在一个实施例中，还可以将折叠后的部分区域的显示功能关闭，只在显示区域上进行内容展示，从而节省能耗。例如图15中，折叠部分的区域为A，显示区域为C，故不在区域A上显示，只在区域C上显示，从而节省能耗。
在一个实施例中，还可以将折叠后的区域以及显示屏上对应折叠区域被遮挡的区域的显示功能关闭，从而节省能耗。仍以附图14为例，折叠部分的区域为A，折叠部分区域对应的被遮挡的区域为B，显示区域为C，此时，只在区域C上显示内容，而关闭区域A和B，从而节省能耗。
根据获取的电信号强度计算柔性显示屏的弯折角度，在弯折角度大于预设的第一角度阈值时，在显示区域上展示相应的内容；在弯折角度大于预设的第二角度阈值时，停止在显示区域上展示相应的内容。以附图7为例，附图7中的A到B段的电信号强度保持恒定，表示在直线A和直线B上的检测点处的电信号强度未发生变化，柔性显示屏未发生弯折；B到D段的电信号强度逐渐减小，表示在直线B、C、D上的检测点处发生弯折，且检测点上的触点偏离电阻片中心的偏移量越大，即弯折程度越大；D到E段的电信号强度又保持不变，表示D和E上的检测点处没有发生弯折，对应的右侧图片中的弯折角度为90度。
而对于附图8，A到B段的电信号强度保持恒定，表示在直线A和直线B 上的检测点处的电信号强度未发生变化，柔性显示屏未发生弯折；B到E段的电信号强度逐渐减小，表示在直线B、C、D、E上的检测点处发生弯折，对应的弯折角度为180度。故可以通过电信号强度的变化计算柔性显示屏弯折的角度。
在计算出柔性显示屏的弯折角度之后，假设设定的显示内容的第一角度阈值为30度，即在柔性显示屏发生弯折时，弯折角度超过30度之后才开始在柔性显示屏的显示区域上显示内容，从而避免柔性显示屏在受到误操作时，只有很小角度的弯折，但仍然在显示区域显示内容造成的电量损耗。
进一步的，当弯折角度超过第二角度阈值时，停止在显示区域上的内容显示，这里的第二角度阈值大于第一角度阈值。例如，当弯折角度超过90度之后不再进行显示，从而可以避免弯折角度过大，实际用户的视线被弯折的柔性显示屏阻挡，无法阅读屏幕上显示的内容时，显示屏依然进行内容显示导致的电量浪费。
在一个实施例中，还需要判断与目标检测点相邻的所有检测点的电信号是否发生变化，如果只有目标检测点上的电信号发生变化，而与之相邻的检测点上的电信号均没有发生变化，此时可判断获取到的目标检测点是无效的，可能是由于触点或电阻片损坏产生的错误信号，从而影响对于目标检测点的确定。
在一个实施例中，如附图16所示，图中选取了位于柔性显示屏的不同位置的三个目标检测点A、B、C。其中，考虑相邻的检测点时，只考虑图示中与目标距离传感器距离最短的相邻检测点。
对于位于柔性显示屏中间区域的目标检测点A，与A相邻的检测点有4个，当A处的电信号发生变化，而周围4个点的电信号都不变时，可判定A检测点故障，不能作为判断弯折区域的目标检测点。对于位于柔性显示屏边缘的目标检测点B，与B相邻的检测点有3个，当B处的电信号发生变化，而周围3个点的电信号都不变时，可判定B检测点故障，不能作为判断弯折区域的目标检测点。而对于目标检测点C，与C相邻的检测点有2个，当C处的电信号发生变化，而周围2个点的电信号都不变时，可判定C检测点故障，不能作为判断弯折区域的目标检测点。
需要说明的是，上述相邻检测点的判断仅为本实施例提供的示例，在其他 的实施例中，柔性显示屏上检测点的分布还可以有其他的方式，相邻检测点的判断也可以有多种方式，不限于本实施例提供的示例。
此外，如附图17所示，在一个实施例中还提出了一种柔性显示屏的弯折检测装置，可以在柔性显示屏中精确地检测到弯折的位置，包括电信号接收模块302，目标检测点获取模块304，弯折区域获取模块306，内容展示模块308，其中：
电信号接收模块302，用于接收柔性显示屏上的检测点产生的电信号；
目标检测点获取模块304，用于获取电信号的强度发生变化的目标检测点；
弯折区域获取模块306，用于获取目标检测点的位置，根据目标检测点的位置确定柔性显示屏的弯折区域。
可选的，目标检测点获取模块304还用于：
获取电信号的强度相对于初始强度的变化大于阈值的目标检测点，初始强度为柔性显示屏完全展开时检测到的检测点的电信号的强度。
可选的，装置还包括内容展示模块308，用于：
根据柔性显示屏的弯折区域获取柔性显示屏的显示区域；
在显示区域上展示相应的内容。
可选的，内容展示模块308还用于：
根据获取的电信号强度计算柔性显示屏的弯折角度，
在弯折角度大于预设的第一角度阈值时，在显示区域上展示相应的内容；
在弯折角度大于预设的第二角度阈值时，停止在显示区域上展示相应的内容；
第一角度阈值小于第二角度阈值。
可选的，目标检测点获取模块304还用于：
在检测到与目标检测点相邻的检测点的电信号强度不变时，判定目标检测点无效。
实施本发明实施例，将具有如下有益效果：
通过在柔性显示屏的显示面板上设置贴合的第一膜层和第二膜层，第一膜 层的第一表面上布有矩阵排列的触点，第二膜层的第一表面上布有矩阵排列的电阻片，第一膜层的第一表面与第二膜层的第一表面贴合，触点与电阻片一一对应形成检测点，其中电阻片的电阻值从电阻片的中心向外边缘单调性变化。检测点连接处理器，并将通过的电信号传递给处理器。当柔性显示屏发生弯折时，处理器通过判断接收到的电信号的强度变化，确定柔性显示屏的弯折位置。由于采用测量电阻片和触点之间电信号强度的方法检测柔性显示屏的弯折位置，对于电信号的获取的计算可以有较高的精度，从而能够精确地确定弯折位置。
本领域普通技术人员可以理解实现上述实施例方法中的全部或部分流程，是可以通过计算机程序来指令相关的硬件来完成，所述的程序可存储于一计算机可读取存储介质中，该程序在执行时，可包括如上述各方法的实施例的流程。其中，所述的存储介质可为磁碟、光盘、只读存储记忆体(Read-Only Memory，ROM)或随机存储记忆体(Random Access Memory，RAM)等。
以上所揭露的仅为本发明一种较佳实施例而已，当然不能以此来限定本发明之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本发明权利要求所作的等同变化，仍属于发明所涵盖的范围。
