具体地，透光状态至少包括透光和遮光这两种状态。在调光结构10透光的情况下，外部的光线经过调光结构10照射在温度传感器2上，使得温度传感器2进行温度检测，并且，温度传感器2通过壳体1的调光结构10接收光线，避免了相关技术中温度传感器2设置在显示屏上的情况下，显示屏对光线的影响，使得本申请提出的技术方案提升了检测的准确性。在调光结构10遮光的情况下，使得调光结构10不透明，外部的光线不能够穿过调光结构10照射在温度传感器2上，从而外部不能看到壳体1内部的结构，提升了终端设备整体的美观性。
可以理解的是，终端设备包括壳体1和显示屏，显示屏与壳体1连接，壳体1包括调光结构10，温度传感器2与调光结构10相对设置，也即温度传感器2不设置在显示屏上，而是设置在终端设备的壳体1上，进而避免了在使用温度传感器2时，显示屏亮度对温度传感器2检测准确度的影响。

在具体应用中，液晶膜104设置在壳体1内，且至少第二透光件106设置在壳体1内，从而避免调光结构10外露，对调光结构10起到了保护的作用。液晶膜104由聚乙烯醇缩丁醛树脂(Polyvinyl Butyral，PVB)膜覆盖在最中央，然后置于高压釜或一般的一步法炉子里经过高温高压的过程胶合而成。

在该实施例中，第一导电膜1042、第二导电膜1044均包括镀有氧化铟锡的涤纶树脂膜，使得第一导电膜1042和第二导电膜1044导电能力较强，从而可作为液晶层1040的导电电路，并且，使得第一导电膜1042和第二导电膜1044具有超透明性能，从而避免了第一导电膜1042和第二导电膜1044对光线的阻拦。第一粘接件1046和第二粘接件1048均包括聚乙-乙酸乙酯胶片，使得第一粘接件1046和第二粘接件1048具有较好的粘接性，同时也具有较好的透明性能，在提升对第一导电膜1042和第二导电膜1044的粘接性的同时，还提升了温度传感器2的检测准确性。第一透光件102和第二透光件106均包括玻璃件，进而降低了生产成本和终端设备的重量，同时也提升了终端设备的美观性。
可以理解的是，第一导电膜1042、第二导电膜1044均包括镀有氧化铟锡的涤纶树脂膜，也即第一导电膜1042、第二导电膜1044为ITO-PET膜，第一粘接件1046和第二粘接件1048均包括聚乙-乙酸乙酯胶片，也即第一粘接件1046和第二粘接件1048均为EVA胶片。
根据本申请的一些实施例，如图2和图3所示，调光结构10还包括：控制电路108，控制电路108通过绑定工艺与第一透光件102和液晶膜104连接，控制电路108与第一控制装置3连接。

具体地，控制电路108为电路板。
根据本申请的一些实施例，如图2所示，第一透光件102还包括印刷区1022，印刷区1022包围透光区1020。
在该实施例中，第一透光件102上还设置有印刷区1022，印刷区1022包围透光区1020设置，可在印刷区1022丝印各种颜色的油膜，从而使得终端设备的外观更加美观，且降低了第一透光件102被刮花的概率。

进一步地，第一透光件102为终端设备的电池盖14，将第一透光件102 的厚度设计的比第二透光件106厚一些，一方面保证了电池盖14的强度，另一方面也使得第二透光件106更薄，降低了对光线的阻挡率。
根据本申请的一些实施例，如图6所示，温度传感器2包括：第二控制装置20，与第一控制装置3连接；多个温度探测膜22，设置在第二控制装置20上；第三导电膜24，与第二控制装置20连接，位于第二控制装置20与温度探测膜22之间，任一温度探测膜22均第三导电膜24连接。
在该实施例中，温度传感器2包括第二控制装置20、多个温度探测膜22和第三导电膜24，第二控制装置20与第一控制装置3连接，第三导电膜24位于多个温度探测膜22和第二控制装置20之间，通过第三导电膜24连接温度探测膜22和第二控制装置20，进而温度探测膜22受人体红外线辐射后产生的电流经过第三导电膜24、第二控制装置20传导到第一控制装置3，以供第一控制装置3计算出温度。其中，温度探测膜22非常薄，当温度探测膜22接收到红外线能量以后，温度探测膜22发生形变，从而内部电子发生迁移，产生电流。多个温度探测膜22的设置，增加了温度探测膜22的面积，从而能够非常准确地探测出发出红外线的待测量者的温度。
可以理解的是，温度探测膜22接收红外线能量越高，电流越大，电流大小与人体体温一一对应，电流越大，待测量者的温度越高。
具体地，多个温度探测膜22在第二控制装置20上平铺设置，从而增加了接收红外线的面积，提升了对待测量者的温度检测的准确性。
其中，第二控制装置20为电路板。
根据本申请的一些实施例，如图6所示，温度传感器2还包括：保护膜26，设于温度探测膜22背离第二控制装置20的一侧。
在该实施例中，温度传感器2还包括保护膜26，保护膜26设置在温度探测膜22上，起到保护温度探测膜22的作用。
具体地，保护膜26为超透明膜，从而不影响待测量者发出的红外线的传导。
根据本申请的一些实施例，第三导电膜24包括氧化铟锡膜，保护膜26 包括涤纶树脂膜。
在该实施例中，第三导电膜24包括氧化铟锡膜，氧化铟透过率高，氧化锡导电能力强，从而可以作为温度探测膜22的电路，提升了温度探测膜22检测的准确性，降低了对红外线的阻挡程度。保护膜26包括涤纶树脂膜，涤纶树脂膜具有超透明的特性，从而降低了对红外线的阻挡程度。
具体地，氧化铟锡膜也即ITO薄膜，是利用磁控溅射方法镀上一层氧化铟锡膜产生，在第二控制装置20上镀上该ITO薄膜，氧化铟透过率高，氧化锡导电能力强，从而可以作为温度探测膜22电路。每个温度探测膜22在对角位置与ITO薄膜两个线路连接，充当电路正负极。最终多个温度探测膜22的正负极线路汇集到第二控制装置20的接口位置，再与第二控制装置20的线路连接在一起，使得多个温度探测膜22接收人体红外线辐射以后产生的电流经过ITO薄膜，第二控制装置20传导到第一控制装置3上。涤纶树脂膜也即PET膜，PET膜超透明，贴在温度探测膜22上。
根据本申请的一些实施例，如图4和图5所示，终端设备还包括：凸透镜，设于壳体1内，位于调光结构10与温度传感器2之间。
在该实施例中，终端设备还包括凸透镜，凸透镜设置在壳体1内，位于调光结构10和温度传感器2之间，从而在第一控制装置3控制调光结构10通电的情况下，由壳体1外部发出的红外光线经过调光结构10后经过凸透镜传递到温度传感器2上，增强了红外光线的能量强度，进而提升了温度传感器2检测的准确度。
根据本申请的一些实施例，凸透镜包括菲涅尔透镜4，菲涅尔透镜4包括相对设置的光面40和凸面42，光面40朝向温度传感器2设置，凸面42朝向调光结构10设置，其中，凸面42上设有多圈凸起44，多圈凸起44同心设置。
在该实施例中，凸透镜包括菲涅尔透镜4，菲涅尔透镜4包括光面40和凸面42，在凸面42上设置有多圈凸起44，多圈凸起44同心设置，其中，光面40朝向温度传感器2设置，凸面42产向调光结构10设置，在壳体1 外部的待测量者从菲涅尔透镜4前方经过时，待测量者发出的红外线的不断交替的从凸面42进入光面40，这样就使能接收到的红外信号以忽强忽弱的脉冲形式输入，从而增强其能量幅度。
可以理解的是，菲涅尔透镜4利用透镜的特殊光学远离，在温度传感器2前方产生一个交替变化的“盲区”和“高灵敏区”，以提高它的探测接收灵敏度。当有人从透镜前走过时，人体发出的红外线就不断地交替从“盲区”进入“高灵敏区”，这样就使接收到的红外信号以忽强忽弱的脉冲形式输入，从而增强其能量幅度。
在具体应用中，菲涅尔透镜4的材质为玻璃或聚甲基丙烯酸甲酯(polymethyl methacrylate，PMMA)，整体类似凸透镜的超薄结构，其表面由一些列锯齿形的凹槽组成，相邻凹槽之间形成凸起44。
根据本申请的一些实施例，如图7和图8所示，终端设备还包括：支架5，设于壳体1内，第一控制装置3和温度传感器2与支架5连接。
在该实施例中，终端设备还包括支架5，支架5设置在壳体1内，用于支撑第一控制装置3和温度传感器2。
根据本申请的一些实施例，如图8所示，壳体1包括：壳本体12；电池盖14，与壳本体12连接，电池盖14的至少一部分为调光结构10。
在该实施例中，壳体1包括壳本体12和电池盖14，壳本体12与电池盖14相连接，温度传感器2以及第一控制装置3设置在壳本体12内，电池盖14的至少一部分为调光结构10，也即调光结构10设置在终端设备的背面，从而避免了正面的显示屏对温度传感器2检测的影响。
在具体应用中，电池盖14包括第一透光件102、液晶膜104和第二透光件106，也就是，电池盖14为具有调光功能的电池盖14，也即电池盖14为调光结构10。通电以后，电池盖14变成透明，从而待测量者发出的红外光大面积穿过透明的电池盖14，再穿过提升温度传感器2灵敏度的菲涅尔透镜4，照射到大面积的温度传感器2上，接收的红外光光量大面积提升，从而大大提升了测量待测量者温度的精确度和使用效果。具体地，待测量者 为人体。
如图2至图10所示，根据本申请的一个具体实施例，提出了一种终端设备，包括：电池盖14、菲涅尔透镜4、温度传感器2、支架5和安装在支架5上的第一控制装置3，温度传感器2通过背胶固定在支架5上。电池盖14的至少一部分为调光结构10，调光结构10包括：第一透光件102、液晶膜104、第二透光件106和控制电路108，当不通电时，调光结构10中的液晶膜104里面的液晶呈无规则散布状态排列，光线无法自由穿透；当通电时，调光结构10中的液晶膜104里面的液晶在电流作用下呈规则有序状态排列，光线可以自由穿透，人体发出的红外光穿过电池盖14中的玻璃。
在通电的情况下，当人体发出的红外光穿过调光结构10时，再穿过菲涅尔透镜4，菲涅尔透镜4产生提升红外光探测灵敏度的高灵敏区，即提升了红外光的强度。
温度传感器2包括：第二控制装置20、多个温度探测膜22和第三导电膜24，多个温度探测膜22由16片(也可以是其他数值)大面积的温度探测膜22组成，面积非常大，接收人体发射红外光区域大，从而感应效果非常好。在菲涅尔透镜4的作用下，高灵敏区的红外光照射到大面积的温度探测膜22上，引起温度探测膜22大范围形变，从而产生比较强的电流。电流再通过第二控制装置20，传递到第一控制装置3上。第一控制装置3经过计算(电流与体温一一对应关系)，将人体体温显示在屏幕上。由于面积非常大，能够非常精确地测量出人体体温。
本申请将温度传感器2与第三导电膜24(ITO薄膜)结合，大面积附贴在第二控制装置20上，放置在终端设备的背面，采用具有调光结构10的电池盖14。通电以后，电池盖14上的调光结构10变成透明，从而人体发出的红外光大面积穿过电池盖14，再穿过提升温度传感器2灵敏度的菲涅尔透镜4，照射到大面积的温度传感器2上，接收的红外光光量大面积提升，从而大大提升了测量人体体温精确度和使用效果。
同时温度传感器2放置在终端设备背面，使用起来非常方便，大大提升 了用户使用的方便性，大大提升了用户体验。
具体地，终端设备包括手机等移动终端、可穿戴式设备、平板电脑、膝上型电脑、移动计算机、增强现实(Augmented Reality，AR)设备、虚拟现实(Virtual Reality，VR)设备、掌上游戏机等。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本申请的实施例，本领域的普通技术人员可以理解：在不脱离本申请的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本申请的范围由权利要求及其等同物限定。
