应该理解的是，当元件或层被称作“形成在”另一元件或层“上”时，该元件或层可以直接地或间接地形成在另一元件或层上。也就是，例如，可以存在中间元件或中间层。相反，当元件或层被称作“直接形成在”另一元件或层“上”时，不存在中间元件或中间层。应当以类似的方式来解释其它用于描述元件或层之间的关系的词语(例如，“在...之间”与“直接在…之间”、“相邻的”与“直接相邻的”等)。
这里使用的术语仅是为了描述特定实施例的目的，而不意图限制示例实施例。如这里所使用的，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。还将理解的是，当在此使用术语“包含”和/或“包括”时，说明存在所述特征、整体、步骤、操作、元件和/或组件，但不排除存在或附加一个或多个其它特征、整体、步骤、操作、元件、组件和/或它们的组合。
在本文中，如无特别说明，表述“厚度”指的是层或部件在垂直于基板的上表面 (在使用状态下，基板的上表面为面对使用者的表面)的方向上的尺寸。
图1是根据本公开的一些示例性实施例的调光面板的平面示意图，图2是根据本公开的一些示例性实施例的调光面板沿图1中的线AA’截取的截面图。
结合参照图1和图2，调光面板10可以包括相对设置的第一调光基板1和第二调光基板2、以及夹设在第一调光基板1与第二调光基板2之间的液晶层3。
第一调光基板1可以包括第一衬底基板11、第一电极12、第一绝缘层13和第一取向层14。第一电极12、第一绝缘层13和第一取向层14依次设置在第一衬底基板11上。
第二调光基板2可以包括第二衬底基板21、第二电极22和第二取向层24。第二电极22和第二取向层24依次设置在第二衬底基板21上。
例如，第一衬底基板11和第二衬底基板21可以分别为透明玻璃基板，在此情况下，调光面板10也可以称为调光玻璃。例如，该调光面板10可以应用于建筑、交通及室内装修设计等领域，以实现透明态与非透明态(例如暗态或雾态)之间的切换。
例如，第一电极12和第二电极22可以分别为透明电极，例如，它们可以由诸如氧化铟锡(ITO)等的透明导电材料构成。
在本公开的一些实施例中，液晶层3可以包括染料液晶，具体地，液晶层3可以包括液晶分子以及与液晶分子混合的色性染料分子。例如，色性染料分子可以为二向色性染料分子。
在本公开实施例提供的调光面板中，在不对第一电极12和第二电极22施加电压时，第一电极12和第二电极22之间不产生电场，液晶层3中的液晶分子和色性染料分子均垂直取向，不对光进行吸收，使得调光面板呈现透光状态(即透明态)。在对第一电极12和第二电极22施加预定电压时，第一电极12和第二电极22之间产生电场，液晶层3中的液晶分子和色性染料分子发生偏转，液晶分子在电场作用下水平排列，诱导色性染料分子水平排列，起到吸光作用，使得调光面板呈现不透光状态(即暗态)。
在上面的实施例中，以染料液晶为例对本公开实施例提供的调光面板进行了说明，应该理解的是，本公开实施例提供的调光面板还可以包括其他类型的液晶，包括但不限于，聚合物分散液晶(简称为PDLC)。
图3和图4分别是根据本公开实施例的调光面板的第一调光基板和第二调光基板的平面示意图。
结合参照图1-4，第一调光基板1包括的第一电极12包括多个电极条121，多个电极条121间隔地布置在第一衬底基板11上。即，第一电极12在第一衬底基板11上的正投影形成为多个间隔分布的条形形状。应该理解，每一个电极条121均为透明电极条，例如，每一个电极条121均由诸如ITO的透明导电材料构成。
参照图1和图3，所述调光面板10还可以包括设置在第一衬底基板11上的多条走线15。示例性地，多条走线15可以分别与多个电极条121一一对应。例如，每一条走线15可以是导电材料构成的导电走线。
参照图1和图3，所述调光面板10还可以包括例如IC的驱动电路16，所述驱动电路用于提供控制信号(例如电压信号)。具体地，多条走线15可以分别将对应的电极条121电连接至例如IC的驱动电路16，这样，驱动电路16提供的控制信号可以分别供应至多个电极条121。
第二调光基板2包括的第二电极22可以为面状电极，即，第二电极22在第二衬底基板21上的正投影形成为一个连续分布的平面图形形状，例如，在图4的实施例中，第二电极22在第二衬底基板21上的正投影形成为一个完整的矩形。
示例性地，如图1所示，第一电极12在第一衬底基板11上的正投影落入第二电极22在第一衬底基板11上的正投影内。
应该理解，第二电极22也可以通过导电结构(将在下文详细描述)电连接至例如IC的驱动电路16，这样，驱动电路16提供的控制信号可以供应至第二电极22。
在本公开实施例提供的调光面板中，驱动电路16可以将第一控制信号供应至多个电极条121中的一个或多个，将第二控制信号供应至第二电极22，以在多个电极条121中的一个或多个与第二电极22之间产生电场，使得与供应有所述第一控制信号的一个或多个电极条121对应的部分处于非透明态，而调光面板的其他部分处于透明态。这样，当所述调光面板作为调光玻璃使用时，可以实现类似于“百叶窗”的显示效果。
图5是根据本公开的一些示例性实施例的调光面板的平面示意图，图6是根据本公开的一些示例性实施例的调光面板沿图5中的线BB’截取的截面图。需要说明的是，图5-6图示的实施例的一些结构可以参照上文针对图1-4的描述，而且，相同或相似的部件或结构使用相同的附图标记表示。
结合参照图5和图6，调光面板10可以包括相对设置的第一调光基板1和第二调光基板2、以及夹设在第一调光基板1与第二调光基板2之间的液晶层3。
第一调光基板1可以包括第一衬底基板11、第一电极32、第一绝缘层13、第二绝缘层17和第一取向层14。
第二调光基板2可以包括第二衬底基板21、第二电极22和第二取向层24。第二电极22和第二取向层24依次设置在第二衬底基板21上。
例如，第一电极32和第二电极22可以分别为透明电极，例如，它们可以由诸如氧化铟锡(ITO)、氧化锌锡(IZO)等的透明导电材料构成。
图7和图8分别是根据本公开实施例的调光面板的第一调光基板和第二调光基板的平面示意图。
结合参照图5-8，第一调光基板1包括的第一电极32包括多个第一电极条321和多个第二电极条322。多个第一电极条321位于同一层中，多个第二电极条322位于同一层。为了描述方便，将多个第一电极条321所在的层称为第一电极层321L，将多个第二电极条322所在的层称为第二电极层322L。参照图6，所述第一电极层321L和所述第二电极层322L为不同的层，并且它们之间通过第一绝缘层13隔开。具体地，所述第一电极层321L设置在第一衬底基板11上，第一绝缘层13设置在所述第一电极层321L远离第一衬底基板11的一侧，所述第二电极层322L设置在第一绝缘层13远离第一衬底基板11的一侧，第二绝缘层17设置在所述第二电极层322L远离第一衬底基板11的一侧。
第一绝缘层13设置在所述第一电极层321L与所述第二电极层322L之间，可以起到平坦化和绝缘的作用。例如，第一绝缘层13可以由氮化硅或氧化硅或其他透明绝缘材料制成。
位于所述第一电极层321L中的多个第一电极条321相互平行且间隔地布置，即，所述第一电极层321L包括多个第一电极条321以及多个第一间隙321G，多个第一间隙321G分别位于两个相邻的第一电极条321之间。这样，多个第一电极条321相互电隔离。
在图5和图6所示的实施例中，多个第一电极条321沿第一方向(图示中的X方向)间隔地布置，每一个第一电极条321沿第二方向(图6中垂直于纸面的方向)延伸。在图示的实施例中，所述第一方向和所述第二方向相互垂直。
位于所述第二电极层322L中的多个第二电极条322相互平行且间隔地布置，即，所述第二电极层322L包括多个第二电极条322以及多个第二间隙322G，多个第二间 隙322G分别位于两个相邻的第二电极条322之间。这样，多个第二电极条322相互电隔离。
在图5和图6所示的实施例中，多个第二电极条322沿第一方向(图示中的X方向)间隔地布置，每一个第二电极条322沿第二方向(图6中垂直于纸面的方向)延伸。
在本公开的实施例中，多个第一电极条321和多个第二电极条322形成互补的关系，即，多个第一电极条321和多个第二电极条322的组合在第一衬底基板11上的正投影形成一个无间隙的完整平面。在本文中，表述“无间隙的完整平面”表示多个第一电极条321和多个第二电极条322的组合在第一衬底基板11上的正投影没有任何间隙或空隙，即无缝。换句话说，多个第一电极条321和多个第二电极条322的组合在第一衬底基板11上的正投影可以完全覆盖夹在第一电极32与第二电极22之间的液晶层3在第一衬底基板11上的正投影。
可选地，多个第一电极条321与多个第二间隙322G一一对应。每一个第一电极条321在第一衬底基板11上的正投影与该第一电极条321对应的第二间隙322G在第一衬底基板11上的正投影重合。多个第二电极条322与多个第一间隙321G一一对应。每一个第二电极条322在第一衬底基板11上的正投影与该第二电极条322对应的第一间隙321G在第一衬底基板11上的正投影重合。
换句话说，任一个第一电极条321沿所述第一方向(图6中的X方向)的尺寸等于与它对应的第二间隙322G沿所述第一方向的尺寸。例如，每一个第一电极条321沿所述第一方向的尺寸均相等，该尺寸可以记为W1；每一个第二间隙322G沿所述第一方向的尺寸均相等，该尺寸可以记为W3，在一些示例性的实施例中，W1＝W3。任一个第二电极条322沿所述第一方向的尺寸等于与它对应的第一间隙321G沿所述第一方向的尺寸。例如，每一个第二电极条322沿所述第一方向的尺寸均相等，该尺寸可以记为W2；每一个第一间隙321G沿所述第一方向的尺寸均相等，该尺寸可以记为W4，在一些示例性的实施例中，W2＝W4。再例如，任一个第一电极条321沿所述第一方向的尺寸可以等于每一个第二电极条322沿所述第一方向的尺寸，即，W1＝W2。
更具体地说，第一电极条321靠近与它相邻的第二电极条322的侧面与第二电极条322靠近与它相邻的第一电极条321的侧面彼此重合。例如，如图9所示，第一电极条321具有靠近一个第二电极条322的第一侧面321A和靠近另一个第二电极条322 的第二侧面321B。与该第一电极条321相邻的一个第二电极条322具有靠近该第一电极条321的第三侧面322A，与该第一电极条相邻的另一个第二电极条322具有靠近该第一电极条的第四侧面322B。第一侧面321A与第三侧面322A对齐，第二侧面321B与第四侧面322B对齐。即，第一侧面321A在第一衬底基板11上的正投影与第三侧面322A在第一衬底基板11上的正投影重合，第二侧面321B在第一衬底基板11上的正投影与第四侧面322B在第一衬底基板11上的正投影重合。
参照图5和图7，所述调光面板10还可以包括例如IC的驱动电路16，所述驱动电路用于提供控制信号(例如电压信号)。具体地，多条走线15可以分别将对应的电极条321、322电连接至例如IC的驱动电路16，这样，驱动电路16提供的控制信号可以分别供应至多个电极条321、322。
第二调光基板2包括的第二电极22可以为面状电极。
示例性地，如图5所示，第一电极32在第一衬底基板11上的正投影落入第二电极22在第一衬底基板11上的正投影内。即，第一电极条321和第二电极条322的组合在第一衬底基板11上的正投影落入第二电极22在第一衬底基板11上的正投影内。
应该理解，第二电极22也可以通过导电结构(将在下文详细描述)电连接至例如IC的驱动电路16，这样，驱动电路16提供的控制信号可以供应至第二电极22。
在本公开实施例提供的调光面板中，驱动电路16可以将第一控制信号供应至多个电极条321、322中的一个或多个，将第二控制信号供应至第二电极22，以在电极条321、322中的一个或多个与第二电极22之间产生电场，使得与供应有所述第一控制信号的一个或多个电极条321、322对应的部分处于非透明态，而调光面板的其他部分处于透明态。这样，当所述调光面板作为调光玻璃使用时，可以实现类似于“百叶窗”的显示效果。而且，在本公开实施例提供的调光面板中，第一电极包括的多个电极条之间不存在间隙，即，多个电极条紧密分布，确保了调光面板在非透明态时没有漏光，并且在透明态时不会显示电极条的形状，使得调光面板整体体现为整面的亮态均一效果。这样，当所述调光面板作为调光玻璃使用时，可以提升调光玻璃的整体观感。
此外，在上述实施例中，第一电极条321靠近与它相邻的第二电极条322的侧面与第二电极条322靠近与它相邻的第一电极条321的侧面彼此重合，这样尽量减少了第一电极条与第二电极条之间的电信号干扰，有利于它们与第二电极相互配合形成电场。
可选地，在本公开的实施例中，参照图10，第一电极条321靠近与它相邻的第二电极条322的边缘部分与第二电极条322靠近与它相邻的第一电极条321的边缘部分可以重叠，即二者存在一定的重叠区域。
结合参照图6和图10，多个第一电极条321与多个第二间隙322G一一对应。每一个第一电极条321在第一衬底基板11上的正投影覆盖与该第一电极条321对应的第二间隙322G在第一衬底基板11上的正投影，即每一个第一电极条321在第一衬底基板11上的正投影的面积大于与该第一电极条321对应的第二间隙322G在第一衬底基板11上的正投影的面积。多个第二电极条322与多个第一间隙321G一一对应。每一个第二电极条322在第一衬底基板11上的正投影覆盖与该第二电极条322对应的第一间隙321G在第一衬底基板11上的正投影，即每一个第二电极条322在第一衬底基板11上的正投影的面积大于与该第二电极条322对应的第一间隙321G在第一衬底基板11上的正投影的面积。
换句话说，任一个第一电极条321沿所述第一方向(图10中的X方向)的尺寸大于与它对应的第二间隙322G沿所述第一方向的尺寸。例如，每一个第一电极条321沿所述第一方向的尺寸均相等，该尺寸可以记为W1；每一个第二间隙322G沿所述第一方向的尺寸均相等，该尺寸可以记为W3，在一些示例性的实施例中，W1＞W3。任一个第二电极条322沿所述第一方向的尺寸大于与它对应的第一间隙321G沿所述第一方向的尺寸。例如，每一个第二电极条322沿所述第一方向的尺寸均相等，该尺寸可以记为W2；每一个第一间隙321G沿所述第一方向的尺寸均相等，该尺寸可以记为W4，在一些示例性的实施例中，W2＞W4。再例如，任一个第一电极条321沿所述第一方向的尺寸可以等于每一个第二电极条322沿所述第一方向的尺寸，即，W1＝W2。每一个第一间隙321G沿所述第一方向的尺寸等于每一个第二间隙322G沿所述第一方向的尺寸，即W3＝W4。
在该实施例中，多个第一电极条321和多个第二电极条322的组合在第一衬底基板11上的正投影仍可以形成一个完整的平面，即，多个第一电极条321和多个第二电极条322的组合在第一衬底基板11上的正投影没有任何间隙(即无缝)。这样，确保了调光面板在非透明态时没有漏光，并且在透明态时不会显示电极条的形状，使得调光面板整体体现为整面的亮态均一效果。此外，第一电极条与第二电极条的边缘部分可以相互重叠，有利于实际加工工艺的实施。
例如，第一电极条321在第一衬底基板11上的正投影可与第二电极条322在第一衬底基板11上的正投影重叠，如图10所示，重叠区域可以记为区域OP。该重叠区域OP沿所述第一方向的尺寸(如图10中沿X方向的尺寸)可以为第一电极条321或第二电极条322沿所述第一方向的尺寸的十分之一至三分之一。
返回参照图6，调光面板10还可以包括隔垫物4，以支撑住调光面板的盒厚。例如，所述调光面板的盒厚可以在6～25μm的范围内。可选地，所述隔垫物4可以为球形隔垫物或柱状隔垫物，所述隔垫物4可以由透明材料或非透明材料制成。对于实际的染料液晶型调光面板而言，它在透明态时的透光率在30～40％之间，所以，即使隔垫物4采用非透明材料制成，也不会对调光面板在透明态时的表现造成不利的影响。
例如，上述第一绝缘层13的厚度(即沿垂直于第一衬底基板11的上表面的方向的尺寸)可以为约0.15μm。虽然在上述实施例提供的调光面板中增加了该第一绝缘层13，但是，由于第一绝缘层13的厚度比所述调光面板的盒厚小很多，甚至不及实际加工工艺波动导致的盒厚波动，所以第一电极的两层设计结构对所述调光面板的盒厚影响较小。
继续参照图5和图6，调光面板10还可以包括封框胶5和导电结构6。
封框胶5设置在第一调光基板1与第二调光基板2之间，并且设置在调光面板10四周，以将第一调光基板1与第二调光基板2之间的空间围成一个封闭的空间，避免外界物质对夹设在两个基板之间的液晶层等的损害。
导电结构6设置在第一衬底基板11上。例如，导电结构6可以位于第一电极层321L或第二电极层322L中。当然，本公开的实施例不局限于此，导电结构6也可以形成在其它的层中。例如，导电结构6可以由金属导电材料制成。
如上所述，多条走线15可以分别将对应的电极条121电连接至例如IC的驱动电路16，多条走线15与驱动电路16电连接的区域设置有连接点(PAD)，该区域也可以称为绑定区，如图5和图7所示的绑定区161。
在本文中，为了描述方便，将所述驱动电路16和绑定区161所在的一侧称为所述调光面板的DP(Data Pad的缩写)侧。
例如，导电结构6在第一衬底基板11上的正投影可以具有倒U形的形状。具体地，导电结构6在第一衬底基板11上的正投影位于所述第一衬底基板11的除所述DP侧之外的另外三侧(包括所述DP侧的相对侧以及位于所述DP侧与所述相对侧之间的 左侧和右侧)。
参照图5和图7，所述多条走线15可以包括电连接驱动电路16与第一电极的多个电极条的多条第一走线151和电连接驱动电路16与导电结构6的至少一条第二走线152。
每一条第一走线151分别将多个第一电极条321和多个第二电极条322中的一个电连接至驱动电路16，以实现对多个第一电极条321和多个第二电极条322中的每一个的独立控制。
参照图6，封框胶5中还掺杂有导电粒子52，例如，金球或铜球。导电粒子52一端与导电结构6电连接，另一端与第二电极22电连接。
也就是说，驱动电路16输出的控制信号，可以通过至少一条第二走线152、导电结构6和导电粒子52而供应至第二电极22，从而实现对第二电极22的控制。
需要说明的是，图6中的右下侧的图为图中所示的虚线框包围的区域的局部放大图，以清楚地示出导电粒子52电连接导电结构6与第二电极22。应该理解，在图6中，为了清楚地示出根据本公开实施例的调光面板的各个结构，其中的各个结构或膜层并不是按照实际产品的尺寸或比例绘制的，所以，其中的尺寸和比例不应该理解为对本公开实施例的特别限制。
图11是根据本公开实施例的调光面板沿图5中的线CC’截取的截面图，其示出了所述调光面板10在DP侧处的结构示意图。参照图11，所述调光面板10还可以包括覆盖所述多条走线15的第三绝缘层18，第三绝缘层18可以填充在多条走线15之间，以避免多条走线15之间短路。并且，第三绝缘层18还设置在多条走线15所在的层与封框胶5所在的层之间，以避免走线15通过封框胶5内的导电粒子而与第二电极22电连接，从而避免了第一电极与第二电极之间的短路。
需要说明的是，第三绝缘层18可以与上述第一绝缘层13或第二绝缘层17位于同一层，也可以与上述第一绝缘层13或第二绝缘层17位于不同的层，可以根据实际需要而进行设置。
图12是根据本公开另一些实施例的调光面板沿图5中的线BB’截取的截面图。需要说明的是，图12图示的实施例的一些结构可以参照上文针对图5-11的描述，而且，相同或相似的部件或结构使用相同的附图标记表示，下面重点描述它们的不同之处。还需要说明的是，为了清楚示出所述不同之处，图12中省略了一些结构，例如取向层、 封框胶等。
结合参照图5、图6和图12，调光面板10可以包括相对设置的第一调光基板1和第二调光基板2、以及夹设在第一调光基板1与第二调光基板2之间的液晶层3。
第一调光基板1可以包括第一衬底基板11、第一电极32、第一绝缘层13、第二绝缘层17和第一取向层14。
第二调光基板2可以包括第二衬底基板21、钝化层25、第二电极22和第二取向层24。钝化层25、第二电极22和第二取向层24依次设置在第二衬底基板21上。
例如，钝化层25、上述第一绝缘层13和上述第二绝缘层17可以由相同的材料构成。
参照图12，钝化层25包括多个条形的钝化部251。多个条形的钝化部251沿所述第一方向平行且间隔地布置。多个条形的钝化部251分别与多个第一电极条321一一对应。多个条形的钝化部251在第一衬底基板11上的正投影与多个第一电极条321在第一衬底基板11上的正投影重叠(例如重合)。换句话说，每一个条形的钝化部251在第一衬底基板11上的正投影与该条形的钝化部251对应的一个第一电极条321在第一衬底基板11上的正投影重叠(例如重合)。
在该实施例中，第二调光基板2包括的第二电极22可以为面状电极，即，第二电极22在第二衬底基板21上的正投影形成为一个连续分布的平面图形形状，例如，第二电极22在第二衬底基板21上的正投影形成为一个完整的矩形。
第二电极22设置在钝化层25远离第二衬底基板21的一侧。由于钝化层25包括间隔设置的多个条形的钝化部251，所以，第二电极22的一些部分位于相邻的条形的钝化部251之间的间隙内，另一些部分覆盖条形的钝化部251。参照图12，第二电极22可以包括多个第一电极部221和多个第二电极部222。多个第一电极部221和多个第二电极部222沿所述第一方向交替地布置。第一电极部221在第一衬底基板11上的正投影与第一电极条321在第一衬底基板11上的正投影重叠(例如重合)，第二电极部222在第一衬底基板11上的正投影与第二电极条322在第一衬底基板11上的正投影重叠(例如重合)。
在图12所示的实施例中，第一电极部221比第二电极部222更远离第二衬底基板21。
例如，每一个钝化部251沿垂直于所述第一衬底基板11的方向(即图12中的Y 方向)的尺寸(即厚度)等于每一个第一电极条321沿Y方向的尺寸(即厚度)。再例如，每一个钝化部251沿垂直于所述第一衬底基板11的方向(即图12中的Y方向)的尺寸(即厚度)、每一个第一电极条321沿Y方向的尺寸(即厚度)和每一个第二电极条322沿Y方向的尺寸(即厚度)彼此相等。
这样，第一电极部221与它对应的第一电极条321之间的垂直距离(即沿Y方向的距离)等于第二电极部222与它对应的第二电极条322之间的垂直距离(即沿Y方向的距离)。通过这样的设置方式，可以实现上、下电极之间的距离一致，从而可以确保产生的电场均一。所以，所述调光面板的整体显示观感得以提升。
在该实施例中，通过在上基板上增加一层钝化层，可以实现上、下电极之间的距离一致，特别地，即使下电极采用两层设计结构，仍可以实现上、下电极之间的距离一致。所以，所述调光面板的盒厚可以在3～4μm的范围内，即可以制造出较薄的调光面板。此外，可以利用制造第一电极条的掩模板制造出所述钝化层，即，可以在不增加掩模板的情况下实现调光模板的薄化，有利于降低制造成本。
图13是根据本公开的一些示例性实施例的调光面板的制造方法的流程图。结合参照图5、图6和图13，所述制造方法可以按照以下步骤执行。
在步骤S131中，在第一衬底基板11上制作间隔设置的多个第一电极条321。例如，可以使用第一掩模板，在第一衬底基板11上制作间隔设置的多个第一电极条321。
在步骤S132中，在第一衬底基板11上形成第一绝缘层13。所述第一绝缘层13可以填充于多个第一电极条321之间的间隙中并且覆盖多个第一电极条321。
在步骤S133中，在第一绝缘层13远离第一衬底基板11的一侧形成多个第二电极条322。例如，可以使用第二掩模板，在第一绝缘层13远离第一衬底基板11的一侧形成多个第二电极条322，多个第二电极条322与多个第一电极条321形成互补关系，使得多个第二电极条322和多个第一电极条321的组合在第一衬底基板11上的正投影为一完整的平面图形。
在步骤S134中，在第一衬底基板11上形成第二绝缘层17。所述第二绝缘层17可以填充于多个第二电极条322之间的间隙中并且覆盖多个第二电极条322。
在步骤S135中，在第二衬底基板21上形成面状的第二电极22。
