具体实施方式
下面详细描述本发明的实施方式，实施方式的示例在附图中示出，其中，相同或类似的标号自始至终表示相同或类似的元件或具有相同或类似功能的元件。下面通过 参考附图描述的实施方式是示例性的，仅用于解释本发明，而不能理解为对本发明的限制。
请参阅图1，本发明实施方式的调光片10包括调光层12、导电膜块14。调光层12包括至少两个调光区域122。至少两对导电膜块14与至少两个调光区域122对应。每对导电膜块14设置在对应的调光区域122的两侧并能够在施加工作电压之后独立调节对应的调光区域122的光透过率。
也即是说，每个调光区域122与一对导电膜块14对应，且对应的导电膜块14分别设置在一个调光区域122的两侧。成对导电膜块14可以给对应的调光区域122施加工作电压，从而在形成穿过调光区域122的电场。
本发明实施方式的调光方法可用于调光片10。调光方法包括以下步骤：
控制施加或断开对应的一对所述导电膜块14的工作电压以独立调节对应的所述调光区域122的光透过率。
本发明实施方式提供的控制装置可用于控制调光片10。控制装置包括控制模块。控制模块用于控制施加或断开对应的一对导电膜块14的工作电压以调节对应的调光区域122的光透过率。
请一并图1和参阅图11，本发明实施方式的调光片10可用于电子装置100。电子装置100包括一个或多个处理器20、存储器30和一个或多个程序32。其中一个或多个程序32被存储在存储器30中，并且被配置成由一个或多个处理器20执行，程序32包括用于执行上述实施方式的调光方法的指令。
本发明实施方式的存储介质存储有处理器20可执行的一个或多个程序32。一个或多个程序32被处理器20执行时实现上述实施方式的调光方法中的步骤。存储介质可由计算机读取。
本发明实施方式的调光片10、调光方法、控制装置、电子装置100和存储介质通过在调光区域122的两侧设置至少两对导电膜块14，每对导电膜块14能独立地施加或断开对应的调光区域122的工作电压来调节调光区域122的光透过率，并且不影响相邻的调光区域122的工作电压。如此，调光片10能实现局部调光以应用于更多的场合。
具体地，调光片10在工作时，某一位置的一对导电膜块14对一个调光区域122独立施加工作电压，调光层12中的液晶分子在电场作用下排列整齐，调光层12由低光透过率转变为高光透过率，即调光片10呈现透明状态。其他位置的导电膜块14未对调光区域122施加工作电压，调光层12中的液晶分子排列混乱，调光层12保持低光透过率，即调光片10呈现雾化状态。也即是说，整体上调光片10一部分是透明状态，一部分是雾化状态，并且透明区和雾化区可以自由组合以形成图案。如此，可以 通过改变施加在与导电膜块14对应的调光区域122的工作电压，来改变不同位置的调光片10的光透过率，从而应用于更多的场合。
可以理解，调光片10和电子装置100可以应用于各种窗户(比如落地窗、车窗)，也可以用作室内屏风或者建筑物的玻璃幕墙。调光片10还可以应用于投影显示、光学调制器、光阀等。
在某些实施方式中，调光层12包括两片基材和填充在所述两片基材之间的液晶和高分子。可以理解，调光层12由液晶和高分子的混合物制成。液晶在施加工作电压时与高分子的折射率相近，因此调光层12呈现透明状态。液晶在断开工作电压时与高分子的折射率相差很大，因此调光层12呈现雾化状态。可以理解，雾化状态呈乳白色，相对于透明状态也称为不透明状态。
在某些实施方式中，高分子可以为聚氨酯丙烯酸酯(PUA)。采用聚氨酯丙烯酸酯(PUA)可以降低调光层12的阈值电压，从而使调光片10工作效率高且节能。
可以理解，调光层12的光透过率与导电膜块14施加在调光区域122两端的工作电压有关。以某种液晶调光膜的技术指标为例。该种液晶调光膜的工作电压为18V至75V。高于75％的光透过率称为透明状态，低于2％的光透过率称为雾化状态。也即是说，当导电膜块14施加的电压低于一定的阈值(18V)时，调光片10的光透过率低于2％，因此调光片10呈雾化状态。当导电膜块14施加的电压高于一定的阈值(75V)时，调光片10的光透过率高于75％，因此调光片10呈透明状态。当导电膜块14施加的电压介于18V至75V时，工作电压越大，调光片10的光透过率越大。
在某些实施方式中，基材可以为玻璃或者膜片。当基材是玻璃时，调光片10是调光玻璃。调光玻璃可以应用在各种窗户上。在其他实施方式中，玻璃可以为双层玻璃，调光片10设置在双层玻璃之间。如此，设置有调光片10的玻璃装置也能实现局部调光。当基材是膜片时，调光片10是柔韧性较好的调光膜。此时调光片10可应用于平面上，也可以应用在曲面上。此外，调光膜还可以与玻璃结合使用。调光膜可以贴附在玻璃的一侧。
在某些实施方式中，基材还可以为PC板(主要成分为聚碳酸酯)。PC板透光性高，硬度大。如此，能增强调光片10的支撑强度。
本发明实施方式中调光层12为一整层连续的结构，也就是说，相邻调光区域122内的液晶和高分子实际上是连通的，并没有实质的物理区隔。如此，整个调光片10都可以在导电膜块14施加工作电压时改变透光率。
在其他实施方式中，调光区域122可以根据用户需求生产通过添加物理间隔以使调光区域122具有不同的形状和大小。比如，对于有特殊图案(比如玫瑰花)的调光 片10，当一个调光区域122对应设置成一片花瓣的形状时，通过间隔调光区域122以使调光区域122的形状和大小可以不同。
本发明实施方式中位于调光层12同一侧的各导电膜块14呈非连续分布，也就是说，位于调光层12同一侧的相邻的导电膜块14相互分离，二者之间通过间隙隔开，以避免导通。
在某些实施方式中，在调光层12内部通过添加物理间隔以使调光区域122形成特定的形状后，导电膜块14的形状与对应的调光区域122的形状对应。可以理解，本发明实施方式的对应的意思是指形状相同或者相似。也即是说，导电膜块14的形状与调光区域122的形状对应。
在某些实施方式中，导电膜块14在对应的调光区域122的正投影落在对应的调光区域122内。可以理解，由于位于调光层12同一侧的相邻的导电膜块14需要避免导通，因此，成对的导电膜块14设置在调光区域122的两侧且调光区域122的同一侧的导电膜块14间隔。也即是说，导电膜块14的大小小于调光区域122的大小。
进一步地，导电膜块14的大小与对应的调光区域122的大小对应。可以理解，导电膜块14的大小与调光区域122的大小有关。为了让成对的导电膜块14可以基本覆盖住一个调光区域122并在施加电压时形成穿过调光区域122的电场。本发明实施方式的导电膜块14略小于调光区域122。
导电膜块14的材料为透明导电材料以满足调光片10双面透光的要求。可以采用的透明导电材料有氧化铟锡(Indium tin oxide，ITO)、纳米银线、金属网格(metal mesh)、纳米碳管以及石墨烯(Graphene)等。
请参阅图2，在某些实施方式中，调光片10还包括透明触摸传感器16和控制器18。透明触摸传感器16与至少两对导电膜块14对应。透明触摸传感器16设置在导电膜块14上。
控制器18与透明触摸传感器16和多个导电膜块14连接。控制器18用于在透明触摸传感器16检测到触摸时控制施加或断开对应的一对或多对导电膜块14的工作电压，如此调节对应的调光区域122的光透过率。
可以理解，透明触摸传感器16上形成有触控区162。触控区162可以用于检测触摸在透明触摸传感器16上的触摸轨迹。可以理解，导电膜块14与触摸区162对应。当触控区162识别到触摸动作时，触控区162将触摸信号转变为坐标信号并传递给控制器18。控制器18接收坐标信息并确定与坐标对应的导电膜块14的位置。然后控制器18控制导电膜块14施加或者断开对应的调光区域122的工作电压，从而调节调光区域122的光透过率。如此，通过触摸操作来实现对调光片10的局部调光。
请再次参阅图2，在某些实施方中，调光片10还包括粘合透明触摸传感器16和导电膜块14的光学透明胶层1a。
可以理解，透明触摸传感器16通过光学透明胶与调光层12粘合。光学透明胶可以为环氧树脂胶等液态非导电胶。光学透明胶的光透过率高，不影响调光片10的光透过率。
在某些实施方中，透明触摸传感器16可以为柔性透明触摸传感器。如此调光片10可以应用于平面，也可以应用于曲面。当透明触摸传感器16为柔性透明触摸传感器时，透明触摸传感器16可以通过光学透明胶以整面的形式贴附在导电膜块14上，即一张薄膜透明触摸传感器16可以对应多个调光区域122(比如一张薄膜透明触摸传感器16对应9个调光区域122)。如此，省去将大面积的透明触摸传感器16切割成小单元面积的透明触摸传感器16的步骤。
可以理解，本发明实施方式的透明触摸传感器16可以为电阻式透明触摸传感器或电容式透明触摸传感器，也可以是超声波透明触摸传感器。对于不同的透明触摸传感器16，对应的导电膜块14及控制器18作相应的调整。比如，超声波透明触摸传感器可以采用压电元件(比如压电陶瓷)。压电元件体积较小，可以以矩阵的排列形式贴附在调光层12上，并且与导电膜块14一一对应。
请一并参阅图2和图3，现在以ITO为例说明导电膜块14在调光片10的分布。调光片10包括柔性电路板11、引线13和边框15。导电膜块14以矩阵的形式排列在调光层12上，且与调光区域122和透明触摸传感器16对应。每个导电膜块14都通过引线13与柔性电路板11连接。柔性电路板11与控制器18连接。在某些实施方式中，引线13可以压合至柔性电路板11内以收纳引线13。边框15可以在防止调光片10的四周边缘磨损的同时，还可以防止调光层12上的材料漏出并起到绝缘保护的作用。
进一步地，单位面积排列的导电膜块14的数量越多，越能精细地调节调光片10的透光状态。
为了使本领域的技术人员更加清楚地了解调光片10如何通过触摸操作来实现对调光片10的局部调光，下面以结合调光片10和调光方法的实施例来具体说明。
本发明实施方式提供的调光方法可用于调光片10。调光方法包括以下步骤：
S10：控制施加或断开对应的一对或多对所述导电膜块的工作电压以独立调节对应的所述调光区域的光透过率。
本发明实施方式的调光方法通过在调光区域122两侧设置成对的导电膜块14，每对导电膜块14能独立地施加或断开对应的调光区域122的工作电压来调节调光区域122的光透过率，并且不影响相邻的调光区域122的工作电压。如此，调光片10能实 现局部调光以应用于更多的场合。
在某些实施方式中，调光片10还包括透明触摸传感器16和控制器18。
请参阅图4，对应地，在步骤S10之前，调光方法还包括以下步骤：
S12：检测触摸在所述调光片上的触摸轨迹；
S14：判断所述触摸轨迹；和
S16：确定与所述触摸轨迹对应的导电膜块。
可以理解，检测功能可以由透明触摸传感器16实现，判断及确定功能可以由控制器18实现。
透明触摸传感器16检测到的触摸轨迹可以分为多种类型。如是否为连续轨迹，触摸轨迹可以分为开放轨迹(起点和终点不重合)和封闭轨迹(起点和终点重合且不包含断点)。如特定的触摸轨迹，触摸轨迹还可以分为方向轨迹(特定方向上的触摸轨迹)和特征轨迹(设定可识别的触摸轨迹，比如数字或者触摸轨迹的长度)。可以理解，透明触摸传感器16检测到触摸轨迹之后，调光片10需要先判断触摸轨迹的种类。判断出触摸轨迹的种类之后，再确定触摸轨迹对应的导电膜块14。
下面以各种触摸轨迹对应的调光方法为实施例，来进一步说明调光片10的调光方法中各个步骤的具体内容。其中，图5(a)、5(b)、5(c)和5(d)为调光片10的四种实施例。
请参阅图6，在某些实施方式中，触摸轨迹包括开放轨迹。在步骤S12之后包括以下步骤：
S142：判断所述触摸轨迹为所述开放轨迹；
S162：确定与所述开放轨迹对应的导电膜块；
S102：控制施加或断开与所述开放轨迹对应的一对或多对所述导电膜块的工作电压以调节对应的所述调光区域的光透过率。
请参阅图5(a)。图5(a)为调光片10检测到触摸轨迹的示意图。具体地，触控区162实时检测到触摸轨迹，并确定触摸轨迹的坐标。控制器18处理坐标信息并确定与坐标对应的多个调光区122。具体地，当控制器18控制导电膜块14给对应的调光区域122施加工作电压时，调光区域122的光透过率变大，即调光片10呈透明状态。也即是说，用户在触控区162触摸，对应位置的调光区域122的光透过率改变，表现为调光片10跟随手指位置的移动而变得透明，而不与坐标对应的调光片10则保持原来的雾化状态。
如此，部分区域的调光片10可以跟随触摸轨迹呈现透明状态。
当控制器18控制导电膜块14断开对应的调光区域122的工作电压时，调光区域122的光透过率变小，即调光片10呈雾化状态。也即是说，用户在触控区162触摸，对应位置的调光区域122的光透过率改变，表现为调光片10跟随手指位置的移动而呈 雾化状态，而不与坐标对应的调光片10保持原来的透明状态。
如此，部分区域的调光片10可以跟随触摸轨迹呈现雾化状态。为更好地表示触摸轨迹对应的调光片10呈雾化状态，图5(a)用加粗线条表示触摸轨迹。
请参阅图7，在某些实施方式中，触摸轨迹包括封闭轨迹。封闭轨迹形成封闭区域。在步骤S12之后包括以下步骤：
S144：判断所述触摸轨迹为所述封闭轨迹；
S164：确定所述封闭区域并确定与所述封闭区域对应的导电膜块；
S104：控制施加或断开与所述封闭区域对应的一对或多对所述导电膜块的工作电压以调节对应的所述调光区域的光透过率。
请继续参阅图5(b)，可以理解，触控区162实时检测到触摸轨迹，并确定触摸轨迹的坐标。控制器18处理坐标信息并判断轨迹是否连续且封闭。当控制器18判断轨迹能形成封闭的区域时，确定与封闭区域对应的多个调光区域122。具体地，当控制器18控制导电膜块14施加与封闭区域对应的调光区域122的工作电压时，调光区域122的光透过率变大，即调光片10呈透明状态。也即是说，当用户在触控区162触摸并形成封闭轨迹时，对应位置的调光区域122的光透过率改变，表现为调光片10在封闭区域内变得透明，而封闭区域外对应的调光区域122保持原来的雾化状态。
如此，调光片10可以根据触摸轨迹来确定封闭区域，使得封闭区域呈现透明状态。
当控制器18控制导电膜块14断开与封闭区域对应的调光区域122的工作电压时，调光区域122的光透过率变小，即调光片10呈雾化状态。也即是说，当用户在触控区162触摸并形成封闭轨迹时，对应位置的调光区域122的光透过率改变，表现为调光片10在封闭区域内呈雾化状态，而封闭区域外对应的调光片10保持原来的透明状态。图5(b)表示封闭区域内呈雾化状态，封闭区域外呈透明状态。
如此，调光片10可以根据触摸轨迹确定封闭区域，使得封闭区域呈现雾化状态。图5(b)为调光片10上封闭区域呈雾化状态的示意图。
当控制器18判断触摸轨迹不能形成封闭的区域时，调光片10可以跟随触摸轨迹呈现透明或者雾化状态。
请参阅图8，在某些实施方式中，触摸轨迹包括方向轨迹。方向轨迹包括第一方向和与第一方向互相垂直的第二方向。方向轨迹在第一方向上包括第一长度，在第二方向上包括第二长度。第一长度和第二长度形成包围方向轨迹的矩形区域。在步骤S12之后包括以下步骤：
S146：判断所述触摸轨迹为所述方向轨迹；
S166：确定所述矩形区域并确定与所述矩形区域对应的导电膜块；和
S106：控制施加或断开与所述矩形区域对应的一对或多对所述导电膜块的工作电压以调节对应的所述调光区域的光透过率。
请继续参阅图5(c)，可以理解，触控区162的第一方向可以为调光片10的横向(平行于水平线)，也可以为调光片10的纵向(垂直于水平线)，还可以为对角线方向(与水平线成45°角)，本发明实施方式并不限定第一方向具体为哪种方向。对应地，当第一方向为调光片10的横向时，第二方向为调光片10的纵向。触摸轨迹在第一方向上的有效长度称为第一长度，在第二方向上的有效长度称为第二长度。第一长度和第二长度可以形成包围触摸轨迹的矩形区域。如图5(c)所示，方向轨迹如第一长度和第二长度确定矩形区域。
具体地，触控区162实时检测到触摸轨迹，并确定触摸轨迹的坐标。控制器18处理坐标信息并确定触摸轨迹在第一方向上的第一长度和在第二方向上的第二长度。控制器18根据第一长度和第二长度确定矩形区域，然后控制器18确定与矩形区域对应的多个调光区域122。
当控制器18控制导电膜块14施加与矩形区域对应的调光区域122的工作电压时，调光区域122的光透过率变大，即调光片10呈透明状态。也即是说，用户在触控区162触摸，与矩形区域对应的调光区域122的光透过率改变，表现为矩形区域内的调光片10变得透明，而矩形区域外的调光片10保持原来的雾化状态。
如此，调光片10可以根据触摸轨迹确定矩形区域，使得矩形区域呈现透明状态。
当控制器18断开与封闭区域对应的调光区域122的工作电压时，调光区域122的光透过率变小，即调光片10呈雾化状态。也即是说，当用户在触控区162触摸时，与矩形区域对应的调光区域122的光透过率改变，表现为矩形区域内的调光片10呈雾化状态，而矩形区域外的调光片10保持原来的透明状态。图5(c)为调光片10上矩形区域呈雾化状态的示意图。
如此，调光片10可以根据触摸轨迹确定矩形区域，使得矩形区域呈现雾化状态。
请参阅图9，在某些实施方式中，触摸轨迹包括特征轨迹。特征轨迹包括长度轨迹和数字轨迹。长度轨迹包括有效长度。在步骤S12之后包括以下步骤：
S148：判断所述触摸轨迹为所述特征轨迹；
S168：识别所述长度轨迹对应的有效长度或者识别所述和数字轨迹对应的数字；
S108：控制施加或断开对应的一对或多对所述导电膜块的工作电压以使所述调光区域的光透过率调节至对应的与所述有效长度或者数字对应的光透过率。
请继续参阅图5(d)，可以理解，调光片10可以识别特定的触摸轨迹来控制调光片10的调光率。其中，调光片10的光透过率与施加在调光区域122的工作电压大小有关。 施加在调光区域122的工作电压越大，调光片10的光透过率越大。调光区域122的工作电压大小由控制器18控制。
具体地，设定特征轨迹，比如数字轨迹。当触控区162检测到数字时，控制器18根据特征轨迹调节对应的导电膜块14的工作电压，从而使调光片10的光透过率调节至与数字对应的调光率。比如，在调光片10的触控区162输入数字“50”，控制器18将调光片10的光透过率调成50％。调光片10可以通过相关的软件识别触控区162的数字。
设定的特征轨迹还可以为长度轨迹。长度轨迹包括方向和在该方向上的有效长度。当触控区162检测到长度轨迹时，控制器18根据长度轨迹调节对应的导电膜块14的工作电压，从而使调光片10的光透过率调节至与有效长度对应的调光率。长度轨迹的方向可以为调光片10的横向，还可以为调光片10的纵向。以图5(d)所示的横向为例，用户在调光片10横向滑动有效长度为L1的轨迹。该有效长度与触控区162在横向上的横向长度L2比值为1：5，则控制器18将调光片10的光透过率调节至20％。有效长度与触控区162在该方向上的长度比值越大，调光片10的光透过率可以调节地越大。也即是说，用户的手指在触控区162滑动的距离越大，调光片10的光透过率越大。
在某些实施方式中，调光片10还可以包括偏振光片。偏光片可以贴附在透明触摸传感器16与导电膜块14之间。偏振光片可以使不具偏极性的自然光转变成偏振光，即只让特定方向的光穿过调光片10且吸收或者反射非特定方向的光。如此，可以在提高调光片10的光透过率和视角范围的同时，使调光片10具有防眩的功能。下面以投影机为例说明调光片10上设置偏振光片的有益效果。投影机从内部灯管发出的光经过设置有偏振光片的调光片10之后，无偏振方向的光偏振化，从而使得投影到墙上的光更加集中。如此，投影机可以提高投影的亮度。
在某些实施方式中，调光片10还可以包括滤光片。自然光穿过带有滤光片的调光片10可以过滤一些波长的光。以红外滤光片为例，红外滤光片只让红外光穿过调光片10，而过滤掉红外光波长范围以外的光，如此调光片10可用于红外监控摄像头上或者其他红外设备上。
可以理解，在某些实施方式中，调光片10还可以包括其他器件。其他器件可以给调光片10带来附加的功能，比如添加彩色滤光片使调光片10呈现彩色。本发明实施方式并不限定通过直接在调光片10上添加器件或者改变调光片10的结构，而使调光片10添加特定的功能。
请参阅图10，图10为本发明实施方式提供的控制装置。控制装置可用于控制调光片10。控制装置包括控制模块。控制模块用于控制施加或断开对应的一对或多对导电 膜块14的工作电压以调节对应的调光区域122的光透过率。
可以理解，控制模块与控制器18对应。
在某些实施方式中，控制装置还包括检测模块和判断模块。检测模块用于检测触摸在调光片10上的触摸轨迹。判断模块用于判断触摸轨迹和确定与触摸轨迹对应的导电膜块14。
可以理解，检测模块与透明触摸传感器16对应，判断模块与控制器18对应。
请参阅图11，本发明实施方式的调光片10可用于电子装置100。电子装置100包括一个或多个处理器20、存储器30和一个或多个程序32。其中一个或多个程序32被存储在存储器30中，并且被配置成由一个或多个处理器20执行，程序32包括用于执行上述任一实施方式的调光方法的指令。
处理器20除了可以用于处理程序32上的指令，还可以用于判断触摸轨迹和确定与触摸轨迹对应的导电膜块14。
存储器30除了可以存储程序32，还可以存储与触摸轨迹有关的参数(比如触摸位置、触摸压力大小等)。
