具体实施方式
下面将结合附图，对本公开一些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公开一部分实施例，而不是全部的实施例。基于本公开所提供的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。
除非上下文另有要求，否则，在整个说明书和权利要求书中，术语“包括(comprise)”及其其他形式例如第三人称单数形式“包括(comprises)”和现在分词形式“包括(comprising)”被解释为开放、包含的意思，即为“包含，但不限于”。在说明书的描述中，术语“一个实施例(one embodiment)”、“一些实施例(some embodiments)”、“示例性实施例(exemplary embodiments)”、“示例(example)”、“特定示例(specific example)”或“一些示例(some examples)”等旨在表明与该实施例或示例相关的特定特征、结构、材料或特性包括在本公开的至少一个实施例或示例中。上述术语的示意性表示不一定是指同一实施例或示例。此外，所述的特定特征、结构、材料或特点可以以任何适当方式包括在任何一个或多个实施例或示例中。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本公开实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在描述一些实施例时，可能使用了“连接”及其衍伸的表达。例如，描述一些实施例时可能使用了术语“连接”以表明两个或两个以上部件彼此间有直接物理接触或电接触。这里所公开的实施例并不必然限制于本文内容。
“A和/或B”，包括以下三种组合：仅A，仅B，及A和B的组合。
如本文中所使用，根据上下文，术语“如果”任选地被解释为意思是“当……时”或“在……时”或“响应于确定”或“响应于检测到”。类似地，根据上下文，短语“如果确定……”或“如果检测到[所陈述的条件或事件]”任选地被解释为是指“在确定……时”或“响应于确定……”或“在检测到[所陈述的条件或事件]时”或“响应于检测到[所陈述的条件或事件]”。
本文中“适用于”或“被配置为”的使用意味着开放和包容性的语言， 其不排除适用于或被配置为执行额外任务或步骤的设备。
另外，“基于”的使用意味着开放和包容性，因为“基于”一个或多个所述条件或值的过程、步骤、计算或其他动作在实践中可以基于额外条件或超出所述的值。
如本文所使用的那样，“约”或“近似”包括所阐述的值以及处于特定值的可接受偏差范围内的平均值，其中所述可接受偏差范围如由本领域普通技术人员考虑到正在讨论的测量以及与特定量的测量相关的误差(即，测量系统的局限性)所确定。
本文参照作为理想化示例性附图的剖视图和/或平面图描述了示例性实施方式。在附图中，为了清楚，放大了层和区域的厚度。因此，可设想到由于例如制造技术和/或公差引起的相对于附图的形状的变动。因此，示例性实施方式不应解释为局限于本文示出的区域的形状，而是包括因例如制造而引起的形状偏差。例如，示为矩形的蚀刻区域通常将具有弯曲的特征。因此，附图中所示的区域本质上是示意性的，且它们的形状并非旨在示出设备的区域的实际形状，并且并非旨在限制示例性实施方式的范围。
此处，在车室外较亮进而使得车室内较亮的情况下，用户可能会具有展开窗帘以对从车室外经窗口射向车室内光线进行遮挡的需求。此时，如果将窗帘展开，则会对设置在窗口内的显示屏形成遮挡，难以再通过显示屏看新闻、看视频或者逛网店等。
基于此，本公开的一些实施例提供了一种触控显示系统100。如图1和图2所示，该触控显示系统100，包括：调光玻璃1，显示屏2，红外触摸装置3，以及分别与调光玻璃1、显示屏2和红外触摸装置3电连接的控制器4。
在一些实施例中，上述显示屏2为透明的显示屏2。这样在显示屏2进行画面显示的情况下，可以供用户浏览画面；在显示屏2停止画面显示的情况下，显示屏2在外观上则类似于透明的玻璃，使得用户能够透过显示屏2观看车窗外的景象。
在一些示例中，显示屏2的结构包括多种，可以根据实际需要选择设置。例如，显示屏2可以为透明的OLED(Organic Light Emitting Diode，有机发光二极管)显示屏。又如，显示屏2可以为透明的LCD(Liquid Crystal Display，液晶显示装置)。
上述调光玻璃1的类型包括多种，可以根据实际需要选择设置。示例性的，上述调光玻璃1可以为电控型的调光玻璃、温控的调光玻璃、光控的调光玻璃、或者压控的调光玻璃。
下面以上述上述调光玻璃1为电控型的调光玻璃为例，对调光玻璃1的结构进行示意性说明。
在一些实施例中，如图3～图8所示，调光玻璃1包括至少一个子调光玻璃11，每个子调光玻璃11包括：相对设置的第一基板111和第二基板112，以及设置在第一基板111和第二基板112之间的染料液晶层113。
此处，以调光玻璃1包括一个子调光玻璃11为例，对调光玻璃1的结构进行示意性说明。
在一些示例中，如图3～图6所示，第一基板111包括第一衬底基板1111，设置在第一衬底基板1111靠近第二基板112一侧的第一电极层1112，以及设置在第一电极层1112靠近第二基板112一侧的第一取向层1113。第二基板112包括第二衬底基板1121，设置在第二衬底基板1121靠近第一基板111一侧的第二电极层1122，以及设置在第二电极层1122靠近第一基板111一侧的第二取向层1123。
在一些示例中，如图3～图6所示，上述染料液晶层113包括液晶分子1131，以及能够吸收光线的染料1132。在染料液晶层113中，染料1132的长轴与液晶分子1131的长轴相互平行或者基本相互平行。在液晶分子1131发生偏转的情况下，染料1132会在液晶分子间作用力的作用下，与液晶分子1131产生同位相的转动。染料1132的旋转角度不同，则染料1132对光线的吸收率不同。
示例性的，上述子调光玻璃11为常白模式的调光玻璃。
基于此，在未给第一电极层1112和第二电极层1122中传输驱动电压的情况下，如图3所示，染料液晶层113中，液晶分子1131的长轴和染料1132的长轴均垂直或者大致垂直于第一取向层1113(或第二取向层1123)。此时，在光线射向子调光玻璃11时，由于染料1132基本未对光线进行吸收，或者仅仅吸收较小部分的光线，且染料1132在子调光玻璃11所在平面占据的面积较小，可以使得较大部分的光线透过子调光玻璃11，进而使得子调光玻璃11基本处于透明的状态。
在给第一电极层1112和第二电极层1122中传输驱动电压的情况下(例如传输至第一电极层1112的电压为正电压，传输至第二电极层1122的电压为负电压)，如图4所示，第一电极层1112和第二电极层1122可以产生电场，该电场能够驱动染料液晶层113中的液晶分子1131偏转，液晶分子1131在偏转的过程中，能够带动染料1132发生旋转。例如，如图4所示，液晶分子31偏转至其长轴平行或大致平行于第一取向层1113(或第二取向层1123) 的方向，并带动染料1132旋转至其长轴平行或大致平行于第一取向层1113(或第二取向层1123)的方向。此时，在光线射向子调光玻璃11时，由于染料1132能够吸收大部分或者全部的光线，且染料1132在子调光玻璃11所在平面占据的面积较大，可以使得光线难以透过子调光玻璃11(不排除会有小部分光线透过子调光玻璃11的情况)，进而使得子调光玻璃11基本处于不透明的状态。
这样在将上述触控显示系统100设置在车辆的窗口的情况下，可以使得调光玻璃1(也即上述子调光玻璃11)具有传统窗帘的功能，也即，在给调光玻璃1施加驱动电压时，可以利用调光玻璃1对外界射向车室内的光线进行吸收(相当于拉展开的窗帘对光线形成遮挡)，降低车室内的亮度；在停止给调光玻璃1施加驱动电压时，可以避免对外界射向车室内的光线进行吸收(相当于合拢的窗帘未对光线形成遮挡)，使得车室内具有较高的亮度。而且，将触控显示系统100设置在车辆的窗口，可以利用调光玻璃1代替传统窗帘，避免额外设置传统窗帘，降低车室内部结构的复杂程度，降低车室内部结构出现异常的概率。
在一些示例中，如图1和图2所示，上述显示屏2设置在调光玻璃1的一侧。示例性的，该调光玻璃1的一侧可以为调光玻璃1的靠近车室内的一侧。这样在调光玻璃1处于不透明的状态的情况下，可以避免影响用户对显示屏2所显示的画面的浏览。
在一些示例中，在将上述触控显示系统100设置在车辆的窗口的情况下，第一基板111和第二基板112的设置位置，可以根据实际需要选择设置。
例如，第一基板111可以相对于第二基板112靠近车室内，第二基板112相对于第一基板111靠近车室外。又如，第二基板112可以相对于第一基板111靠近车室内，第一基板111相对于第二基板112靠近车室外。
在一些示例中，上述第一基板111和第二基板112均为透明的基板。也即，第一基板111所包括的各种结构的材料和第二基板112所包括的各种结构的材料为透明的材料。这样可以避免第一基板111和第二基板112对光线的传播过程产生不良影响，使得子调光玻璃11在透明状态下具有较好的透光率。
示例性的，上述第一衬底基板1111和第二衬底基板1121可以为玻璃衬底基板。这样可以确保子调光玻璃11具有一定的强度，而且，在子调光玻璃11处于透明状态时，可以避免影响子调光玻璃11的透光率。
示例性的，第一电极层1112和第二电极层1122的材料可以相同，也可 以不同。例如，第一电极层1112和第二电极层1122的材料相同，该材料可以为氧化铟锡(Indium Tin Oxide，简称ITO)、氧化铟锌(Indium Zinc Oxide，简称IZO)或者氧化铟镓锌(Indium Gallium Zinc Oxide，简称IGZO)等。这样可以使得子调光玻璃11具有较好的透光率，避免因第一电极层1112和第二电极层1122的设置而对子调光玻璃11的透光率产生不良影响。
示例性的，第一取向层1113和第二取向层1123的材料可以相同，也可以不同。例如，第一取向层1113和第二取向层1123的材料相同，该材料可以为聚酰亚胺、N-甲基吡咯烷酮和乙二醇丁醚的混合物，或者，可以为丙烯酸羟乙酯、3-异氰酸酯基亚甲基-3，5，5-三甲基环己基异氰酸酯、双酚基丙烷或1，4-环己二醇的聚合物。这样在子调光玻璃11处于透明状态时，可以避免影响子调光玻璃11的透光率。
在一些实施例中，如图12和图13所示，上述红外触摸装置3被配置为，在显示屏2远离调光玻璃1的一侧(也即靠近车室内的一侧)形成红外线探测网。
在一些示例中，如图12所示，该红外线探测网例如可以为由沿第一方向X延伸的多条红外线以及沿第二方向Y延伸的多条红外线构成的红外线矩阵。在用户触摸显示屏2的情况下，会挡住触摸位置处对应的红外线(包括沿第一方向X延伸的红外线和沿第二方向Y延伸的红外线)，通过确定被阻挡的红外线的坐标，即可感测出用户的触摸动作。
此处，用户可以使用例如笔、手指或任何可阻挡光线的物体触摸显示屏2。
在一些示例中，第一方向X与第二方向Y相交叉。
第一方向X和第二方向Y之间的夹角的大小可以根据实际需要选择设置。
例如，第一方向X和第二方向Y可以相互垂直，也即两者之间的夹角为90°。又如。第一方向X和第二方向Y可以不垂直，也即两者之间的夹角可以不等于90°。其中，第一方向X和第二方向Y之间的夹角，例如可以为89°、85°或84°等。
在一些实施例中，上述控制器4被配置为，控制红外触摸装置3感测用户的触摸动作，获取红外触摸装置3感测到的触摸信号，并根据触摸信号3调整显示屏2的显示画面，和/或，调整调光玻璃1的透光率。
在一些示例中，上述触摸动作包括多种。示例性的，该触摸动作例如可以包括单击、双击、沿第一方向X滑动、沿第二方向Y滑动、或画圈等。当然，上述触摸动作并不局限于示例出的几种。
此处，可以对上述触摸动作分为至少两个类型。示例性的，将上述触摸动作分为三个类型，其中一个类型的触摸动作(例如单击、向第二方向Y滑动等)与显示屏2相对应，另一个类型的触摸动作(例如画圈、沿第一方向X滑动等)与调光玻璃1相对应，又一个类型的触摸动作(例如双击等)既与显示屏2相对应，又与调光玻璃1相对应。这样控制器4可以根据触摸动作的类型，调整显示屏2和/或调光玻璃1。
下面对控制器4调整显示屏和/或调整调光玻璃1的过程进行示意性说明。例如，控制器4中存储有与各种触摸动作相对应的协议。
示例性的，用户单击显示屏2。此时，控制器4控制红外触控装置3确定红外线探测网中被挡住的红外线的坐标，并根据该坐标感测出用户的触摸动作为单击。之后红外触控装置3可以生成相应的触摸信号。然后控制器4可以获取该触摸信号，并在判断出该触摸信号与显示屏2相对应之后，调整显示屏2的显示画面。例如，用户单击显示屏2之前，显示屏2所显示的画面为一件衣服的图像；用户在单击显示屏2(例如用户单击显示屏2的位置与该衣服的图像的位置相同)之后，控制器4控制显示屏2更换显示画面为该衣服的简介(例如该衣服的品牌、价格等)。
示例性的，用户沿第一方向X滑动显示屏2。此时，控制器4控制红外触控装置3确定红外线探测网中被挡住的红外线的坐标，并根据该坐标感测出用户的触摸动作为沿第一方向X滑动。之后红外触控装置3可以生成相应的触摸信号。然后控制器4可以获取该触摸信号，并在判断出该触摸信号与调光玻璃1相对应之后，调整调光玻璃1的透光率。例如，用户沿第一方向X滑动显示屏2之前，调光玻璃1处于透明的状态；用户在沿第一方向X滑动显示屏2之后，控制器4调整调光玻璃1中驱动电压的传输状态(例如向调光玻璃1中传输驱动电压)，使得调光玻璃1调整为不透明的状态。
示例性的，用户双击显示屏2。控制器4控制红外触控装置3确定红外线探测网中被挡住的红外线的坐标，并根据该坐标感测出用户的触摸动作为双击。之后红外触控装置3可以生成相应的触摸信号。然后控制器4可以获取该触摸信号，并在判断出该触摸信号与显示屏2和调光玻璃1相对应之后，调整显示屏2的显示画面以及调光玻璃1的透光率。例如，用户双击显示屏2之前，显示屏2所显示的画面为一件衣服的图像，调光玻璃1处于透明的状态；用户在双击显示屏2(例如用户单击显示屏2的位置与该衣服的图像的位置相同)之后，控制器4控制显示屏2更换显示画面为该衣服的简介(例如该衣服的品牌、价格等)，并调整调光玻璃1调整为不透明的状态。
由此，本公开的一些实施例所提供的触控显示系统100，通过设置显示屏2、红外触摸装置3和控制器4，可以将显示功能和触控功能集成在一起，也即通过触摸显示屏2即可实现对显示屏2所显示的画面的调整。而且，通过在显示屏2的一侧设置调光玻璃1，并将该调光玻璃1与控制器4电连接，可以在不需要对射向显示屏2的光线进行遮挡时，可以将调光玻璃1调整为透明的状态，以使得光线能够透过调光玻璃1射向显示屏2；而在需要对射向显示屏2的光线(该光线由调光玻璃1指向显示屏2的方向传播)进行遮挡时，将调光玻璃1调整为不透明的状态，以利用调光玻璃1对射向显示屏2的光线形成遮挡。
此外，在将触控显示系统100应用于车辆的窗口内的情况下，还可以利用调光玻璃1代替传统的窗帘，减少传统窗帘的设置，降低车辆的车室内部结构的复杂程度，降低车室内部结构出现异常的概率；而且，在利用调光玻璃1对外界光线进行遮挡的过程中，还可以避免因调光玻璃1的设置而对用户观看显示屏2所显示的画面产生障碍。
在一些实施例中，如图10和图11所示，调光玻璃1具有多个调光区A。上述控制器4被配置为，分别独立地调整调光玻璃1中各调光区A的透光率。例如，如图11所示，自左向右，仅调整第一个调光区A、第二个调光区A、第八个调光区A和第十个调光区A为不透明的状态，其余的调光区A为透明的状态。
通过在调光玻璃1中划分多个调光区A，可以实现分区域独立调整透光率，使得各调光区A的透光效果互不影响。在将触控显示系统100应用于车辆的窗口内的情况下，相比传统的窗帘，可以满足乘坐在不同位置处的不同用户对光线的不同需求。
上述多个调光区A的排列方式包括多种，可以根据实际需要选择设置。
在一些示例中，上述多个调光区A可以呈块状，并呈阵列式排布。
在另一些示例中，如图10和图11所示，上述多个调光区A可以呈条状，该多个调光区A的长度延伸方向沿第二方向Y，且该多个调光区A沿第一方向依次排布。
需要说明的是，在调光玻璃1具有多个调光区A的情况下，调光玻璃1所包括的至少一个子调光玻璃11中，每个子调光玻璃11可以具有多个子调光区。在调光玻璃1包括一个子调光玻璃11的情况下，该多个子调光区则为上述多个调光区A；在调光玻璃1包括多个子调光玻璃11的情况下，其中一个子调光玻璃11的一个子调光区，可以和其他子调光玻璃11相应位置处的 子调光区相对应(例如尺寸大小相等、且在各自子调光玻璃11中的位置相同)，共同形成一个调光区A。
此处，以调光玻璃1具有多个调光区A、且调光玻璃1包括一个子调光玻璃11为例，对调光玻璃1的结构进行示意性说明。
在一些示例中，如图5和图6所示，调光玻璃1中的第一基板111所包括的第一电极层1112包括多个第一电极11121，一个第一电极11121位于一个调光区A内。例如，第一电极11121和调光区A可以一一对应设置。
此处，调光玻璃1中的第二基板112所包括的第二电极层1122，可以有多种设置方式。
示例性的，如图5所示，第二电极层1122包括多个第二电极11221，一个第二电极11221位于一个调光区A内。例如，第二电极11221和调光区A可以一一对应设置。
这样在调整某个调光区A的透光率时，可以仅在该调光区A内设置的第一电极11121和第二电极11221中传输驱动电压，或者停止向该调光区A内设置的第一电极11121和第二电极11221中传输驱动电压，实现对该调光区A的透光率的独立控制，避免影响其他调光区A的光线透过率。
示例性的，如图6所示，第二电极层1122覆盖上述多个调光区A。此时，第二电极层1122可以为面状电极。
这样在需要将某个调光区A调整为不透明的状态时，可以对第二电极层1122和该调光区A内设置的第一电极11121传输驱动电压，在该第一电极11121和第二电极层1122相对的区域(也即该调光区A)内产生电场，而在其他的第一电极11121和第二电极层1122相对的区域(也即其他的调光区A)内未产生电场，实现对该调光区A的透光率的独立控制，避免影响其他调光区A的光线透过率。
在一些实施例中，如图7～图9所示，调光玻璃1包括依次层叠设置的多个子调光玻璃11。
这样在给调光玻璃1施加驱动电压，以利用调光玻璃1降低车室内的亮度的情况下，可以在光线向车室内传播的过程中，利用各调光玻璃11依次对光线进行吸收，有利于对外界射向车室内的光线进行较为完全的阻挡，确保调光玻璃1具有良好的遮光效果。
上述多个子调光玻璃11之间的设置方式包括多种，可以根据实际需要选择设置。
在一些示例中，如图7所示，调光玻璃1还包括：设置在每相邻的两个 子调光玻璃11之间的粘接层12。该粘接层12被配置为，粘接每相邻的两个子调光玻璃11。
这样可以在独立制备形成多个子调光玻璃11之后，再将多个调光玻璃11依次层叠设置并粘接，可以避免增加制备调光玻璃1的工艺难度。
此处，其中一个子调光玻璃11的第一基板111可以与相邻的子调光玻璃11的第二基板112粘接；或者，其中一个子调光玻璃11的第一基板111可以与相邻的子调光玻璃11的第一基板111粘接；或者，如图7所示，其中一个子调光玻璃11的第二基板112可以与相邻的子调光玻璃11的第二基板112粘接。
在另一些示例中，如图8和图9所示，每相邻的两个子调光玻璃11相互靠近的一侧共用同一个基板。
如图8所示，以上方的子调光玻璃11的第二基板112与下方的子调光玻璃11的第二基板112为同一个基板为例。该基板包括：第二衬底基板1121，设置在第二衬底基板1121的相对两侧的第二电极层1122，以及设置在每个第二电极层1122远离第二衬底基板1121一侧的第二取向层1123。在向调光玻璃1传输驱动电压的过程中，可以向设置在第二衬底基板1121的相对两侧的第二电极层1122传输相同的驱动电压。
通过将每相邻的两个子调光玻璃11相互靠近的一侧共用同一个基板，可以简化调光玻璃1的结构，有效减小调光玻璃1的厚度，进而减小触控显示系统100的整体厚度。并且，还可以减少材料的浪费，降低调光玻璃1的成本。
此处，如图8所示，以调光玻璃1包括依次层叠设置的两个子调光玻璃11、且该两个子调光玻璃11相互靠近的一侧共用同一个基板为例，对制备调光玻璃1的过程进行示意性说明。
示例性的，可以采用溅射沉积工艺或者物理气相沉积(Physical Vapor Deposition，简称PVD)工艺在第二衬底基板1121的相对两侧形成第二电极层1122，并采用相同的工艺在第一衬底基板1111的一侧形成第一电极层1112；然后可以采用涂覆工艺及紫外固化工艺在每个第二电极层1122远离第二衬底基板1121的一侧形成第二取向层1123，并采用相同的工艺在第一电极层1112远离第一衬底基板1111的一侧形成第一取向层1113；然后将其中一个第一取向层1113与一个第二取向层1123相对，在两者之间形成封框胶，在第一取向层1113、第二取向层1123及封框胶构成的空腔内填充液晶分子1131和染料1132，并在填充完成后进行密封，形成一个子调光玻璃11，之后 可以采用相同的步骤形成另外一个子调光玻璃11。此外，在形成子调光玻璃11之后，可以在子调光玻璃的边缘处涂覆密封胶，对子调光玻璃11形成保护。
在一些示例中，上述多个子调光玻璃11中，至少两个子调光玻璃11的染料液晶层113中的液晶分子1131的长轴互相垂直或大致相互垂直。
基于此，在制备该多个子调光玻璃11的过程中，可以对其中至少两个子调光玻璃11的取向层进行配向处理。
示例性的，该配向处理包括摩擦配向处理。其中，至少两个子调光玻璃11的取向层的摩擦方向垂直或大致垂直。
此处，以上述多个子调光玻璃11中的两个子调光玻璃11为例。例如，其中一个子调光玻璃11的第一取向层1113和第二取向层1123的摩擦方向与第一方向X之间可以呈夹角45°，此时，该子调光玻璃11中的液晶分子1131便可以沿着该摩擦方向依次排列，并形成一定的预倾角；另一个子调光玻璃11的第一取向层1113和第二取向层1123的摩擦方向与第一方向X之间可以呈夹角-45°，此时，该子调光玻璃11中的液晶分子1131便可以沿着该摩擦方向依次排列，并形成一定的预倾角。
这样，在未给上述两个子调光玻璃11传输驱动电压的情况下，便可以使得两个子调光玻璃11的染料液晶层113中的液晶分子1131的长轴互相垂直或大致相互垂直。
在给上述两个子调光玻璃11传输驱动电压的情况下，如图9所示，两个子调光玻璃11中的液晶分子1131在发生偏转后，仍可以基本保持长轴互相垂直或大致相互垂直。此时，在车室外的光线射向调光玻璃1时，该两个子调光玻璃11中的液晶分子1131可以相当于两个吸光轴相互垂直的偏光片，能够对光线进行较为完全的吸收(例如可以使得调光玻璃1在不透明的状态下的透光率在1％及以下)，对光线形成良好的遮挡效果。
以上述多个子调光玻璃11中的三个子调光玻璃11为例。例如，其中一个子调光玻璃11的第一取向层1113和第二取向层1123的摩擦方向与第一方向X之间可以呈夹角45°(当然，该夹角不局限于45°)；另一个子调光玻璃11的第一取向层1113和第二取向层1123的摩擦方向与第一方向X之间可以呈夹角-45°(当然，该夹角不局限于-45°)；又一个子调光玻璃11的第一取向层1113和第二取向层1123的摩擦方向与第一方向X之间可以呈夹角22.5°(当然，该夹角不局限于22.5°)。
此时，可以利用第一取向层1113和第二取向层1123的摩擦方向与第一方向X之间呈夹角22.5°的子调光玻璃11对光线进行调配，进一步提升对光 线的吸收效果，进一步提升调光玻璃1对光线的遮挡效果。
在一些示例中，上述多个子调光玻璃11中，至少两个子调光玻璃11的染料液晶层113中染料1132的颜色不同。
这样可以利用不同子调光玻璃11的染料液晶层113中的染料1132，改变透过调光玻璃1的光线的颜色。例如，可以使得自车室外透过调光玻璃1射向车室内的光线，由白色转变为黄色，使得车室内的环境更为温和。
示例性的，以调光玻璃1包括两个子调光玻璃11为例。其中一个子调光玻璃11中的染料1132的颜色可以为玫红色，另一个子调光玻璃11中的染料1132的颜色可以为黄色。这样透过调光玻璃1光线可以转变为橙色。
在一些实施例中，如图2、图12和图13所示，触控显示系统100中的红外触摸装置3包括：边框31。
上述边框31的形状可以与触控显示系统100中的显示屏2的形状相同或者大致相同。其中，调光玻璃1的形状与显示屏2的形状相同或者大致相同。
示例性的，如图12所示，显示屏2的形状和边框31的形状可以为相同或大致相同的矩形。示例性的，显示屏2的形状和边框31的形状可以为如图13所示的形状。
上述边框31的设置包括多种，可以根据实际需要选择设置。
例如，如图1所示，边框31可以设置在显示屏2远离调光玻璃1的一侧。这样在制备触控显示系统100的过程中，将调光玻璃1、显示屏2及红外触摸装置3依次层叠即可，有利于降低触控显示系统100的组装难度，提高触控显示系统100的生产效率。
又如，如图2所示，边框31可以围设在调光玻璃1和显示屏2的周围。这样可以将调光玻璃1、显示屏2及红外触摸装置3紧密地组装在一起，提高调光玻璃1、显示屏2及红外触摸装置3的紧凑程度，进而提高触控显示系统100的结构稳定性。此外，还有利于降低触控显示系统100的厚度。
在一些示例中，上述边框31包括两组子边框311，每组子边框311包括相对设置的两个子边框311。
示例性的，如图12和图13所示，以B1、B2、B3及B4分别表示边框31所包括的各子边框311。上述两组子边框311中，其中一组子边框311包括相对设置的B1和B2，该组子边框311沿第一方向X延伸；另一组子边框311包括相对设置的B3和B4，该组子边框311沿第二方向Y延伸。
在一些示例中，如图12和图13所示，红外触摸装置3还包括：设置在每个子边框311的内壁上的多个红外器件32。
示例性的，如图12和图13所示，相对设置的两个子边框311中，其中一者的内壁上所设置的红外器件32为红外发射器321，另外一者的内壁上所设置的红外器件32为红外探测器322，且一个红外发射器321与一个红外探测器322相对设置。
示例性的，B1的内壁上所设置的红外器件32可以为红外发射器321，则B2的内壁上所设置的红外器件32可以为红外探测器322，此时，每个红外发射器321能够发射出沿第二方向Y延伸的红外线，该红外线能够被相应的红外探测器322探测到。B3的内壁上所设置的红外器件32可以为红外发射器321，则B4的内壁上所设置的红外器件32可以为红外探测器322，此时，每个红外发射器321能够发射出沿第一方向X延伸的红外线，该红外线能够被相应的红外探测器322探测到。
这样两组子边框311的内壁上设置的多个红外器件32便能够形成红外线探测网。
在一些示例中，各边框311上设置的多个红外器件32位于显示屏2远离调光玻璃1的一侧。这样可以确保各红外器件32形成的红外线探测网位于显示屏2远离调光玻璃1的一侧，进而确保能够通过触摸显示屏2实现对显示屏2所显示画面的调整，和/或，对透光玻璃1的透光率的调整。
上述多个红外器件32在相应的子边框311内壁上的设置位置包括多种。其中，该设置位置和边框31的形状相关。
在一些示例中，如图12所示，边框31所包括的各子边框311呈直线状，每相邻的两个子边框311的端部相接。也即，边框31的形状呈矩形。
此时，各子边框311的内壁上所设置的多个红外器件32设置在同一平面内。
这样既可以确保所形成的红外线探测网的有效探测区能够覆盖显示屏2，又可以使得红外触摸装置3具有较小的厚度。
需要说明的是，上述有效探测区指的是，同时包括沿第一方向X延伸的红外线和沿第二方向Y延伸的红外线的区域。
示例性的，各子边框311的内壁上所设置的多个红外器件32所在的平面平行于显示屏2。
这样可以使得每条红外线与显示屏2之间的间距相等或大致相等，提高触摸显示系统100的精准度。
在另一些示例中，如图13所示，边框31还包括：至少一个过渡部312。也即，边框31包括一个过渡部312，或者多个过渡部312。其中，每个过渡 部312呈弧线状，并连接于相邻两个子边框311的相互靠近的端部之间。
此处，如图13所示，以边框31包括一个过渡部312为例。与过渡部312相连的两个子边框311分别为第一子边框(可以为B1)和第二子边框(可以为B3)。
示例性的，如图14和图15所示，过渡部312的内壁上设置有第一组红外器件32和第二组红外器件32。第一组红外器件32与B1上所设置的多个红外器件32类型相同，且处于第一平面内。也即，第一组红外器件32为红外发射器321。第二组红外器件32与B3上所设置的多个红外器件32类型相同，且处于第二平面内。也即，第二组红外器件32为红外发射器321。
示例性的，第一平面和第二平面为平行于显示屏2的不同平面。如图13所示，从俯视图中可以看出，第一组红外器件32和第二组红外器件32可能会出现重叠的情况。通过将第一组红外器件32和第二组红外器件32设置在不同的平面，可以避免出现第一组红外器件32或第二组红外器件32中的某个红外器件32无空间安放的情况，进而确保边框31内设置的红外器件32所形成的红外线探测网的有效探测区能够覆盖显示屏2。
上述过渡部312的设置数量，与显示屏2的形状相关，可以根据实际需要选择设置。
在一些示例中，每相邻两个子边框311之间均连接有一个过渡部32。在此情况下，红外器件32的设置方式可以参照图16和图17中所示的设置方式，以便确保每个红外器件32均有空间安放，且所形成的红外线探测网的有效探测区能够覆盖显示屏2。
