下面参考图1-图7描述根据本申请实施例的用于电子装置300的虹膜识别组件100。其中，虹膜识别组件100可以对电子装置300进行解锁。可选地，电子装置300可以为手机、平板电脑等，但不限于此。
根据本申请实施例的用于电子装置300的虹膜识别组件100，包括：主板110、红外灯120、虹膜摄像头130和盖板140。
具体地，主板110具有第一表面111，红外灯120与主板110连接且位于第一表面111。
虹膜摄像头130与主板110连接，虹膜摄像头130位于第一表面111且与红外灯120间隔开设置。参照图1，虹膜摄像头130与红外灯120可以在左右方向上间隔设置。例如，将虹膜识别组件100应用于电子装置300(例如手机、平板电脑等)时，需要通过虹膜识别对电子装置300进行解锁时，可以使人眼400可以对着虹膜摄像头130，红外灯120发射的光线偏转一定角度被人眼400接收，虹膜摄像头130通过捕捉人眼400接收的红外光，实现解锁。
盖板140位于与主板110间隔开设置，盖板140具有第一透光部141，第一透光部141与红外灯120相对，第一透光部141上设有贴纸1410，贴纸1410上设有第一涂层1411，第一涂层1411被构造成允许红外光线穿透且阻止可见光穿透。其中，贴纸1410可以粘贴在第一透光部141的邻近虹膜摄像头130的一侧表面，也可以粘贴在第一透光部141的远离虹膜摄像头130的一侧表面。由此，通过在第一透光部141上设置贴纸1410，并在贴纸1410上设置第一涂层1411，红外灯120发射的红外光线经人眼400反射后，可以穿透第一透光部141被虹膜摄像头130接收，提高了虹膜摄像头130的识别效率，同时在虹膜识别组件100温度升高、红外光产生漂移时，可以有效地避免可见光对虹膜摄像头130形成干扰且可以避免可见光穿透第一透光部141，从而可以有效地避免虹膜识别光源可见，提高 了虹膜识别组件100的识别效率和使用舒适性。
根据本申请实施例的用于电子装置300的虹膜识别组件100，通过在第一透光部141上粘贴贴纸1410，并在贴纸1410上设置第一涂层1411，红外灯120发射的红外光线经人眼400反射后，可以穿透第一透光部141被虹膜摄像头130接收，，有利于提高红外光线的透射率，提高了虹膜摄像头130的识别效率，同时在虹膜识别组件100温度升高、红外光产生漂移时，可以有效地避免可见光对虹膜摄像头130形成干扰且可以避免可见光穿透第一透光部141，从而可以有效地避免虹膜识别光源可见，提高了虹膜识别组件100的识别效率使用舒适性。
根据本申请的一些具体实施例，贴纸1410粘贴在第一透光部141的邻近虹膜摄像头130的一侧表面上。也就是说，贴纸1410可以粘贴在第一透光部141的内表面上。由此，可以避免第一粘贴1410摩擦脱落，提高了贴纸1410的可靠性，延长了贴纸1410的使用寿命。
这里，需要说明的是，在本申请中，方向“内”指的是朝向电子装置300中心的方向，相应地，“方向外”指的是背向电子装置300中心的方向。
根据本申请的一些实施例，第一涂层1411电镀或丝印在贴纸1410上。也就是说，第一涂层1411可以通过电镀工艺电镀在贴纸1410上，也可以通过丝印工艺印在贴纸1410上。由此，可以将第一涂层1411牢靠地设置在贴纸1410上，提高了第一涂层1411的稳定性和可靠性且工艺简单，加工方便，有利于降低加工成本。
可选地，第一涂层1411为氧化硅氧化钛镀层，但不限于此。由此，可以保证经人眼400反射后的红外光线穿透第一透光部141被虹膜摄像头130接收，且可以阻止可见光穿透第一透光部141，从而可以保证虹膜识别光源不可见。同时，在使用过程中，氧化硅氧化钛镀层可以保证波长范围在900nm以上的红外光线全部穿透第一透光部141，波长为800nm～900nm的红外光线少量穿透，800nm以下的光线完全不可以穿透。
根据本申请的一些实施例，第一涂层1411的颜色与盖板140在第一透光部141周围的颜色具有一致性。也就是说，第一涂层1411的颜色与盖板140在第一透光部141周围的颜色相同或相似。由此，可以提高盖板140外观的一致性，从而可以提高电子装置300的美观度。
例如，在一些实施例中，第一涂层的颜色为白色、金属色或银色等浅色，盖板140在第一透光部141周围的颜色也为相同或相似的白色、金属色或银色等浅色。
在一些实施例中，上述的颜色具有一致性为指在Lab色彩模式中，两个物体之间的色差在可接受的范围内。具体地，第一涂层1411的颜色与盖板140在第一透光部141周围的颜色的色差ΔEab满足：0≤ΔEab≤5，进一步地，ΔEab满足0≤ΔEab≤2。
以两个彩色样品为例，若两个彩色样品都按L、a、b标定颜色，其中，L代表亮度，范 围在0-100，最暗为0，最亮为100；a是由绿到红的色彩变化，范围在-128～+128，纯绿为负128，纯红为正128，之间分为256级；b是由蓝到黄的色彩变化，范围在-128～+128，纯蓝为负128，纯黄为正128，之间分为256级，则两个彩色样品的颜色标定分别为：彩色样品一标定为L1，a1及b1；彩色样品二标定为L2，a2及b2。则两个彩色样品之间的色差ΔEab可用下列公式计算：色差ΔEab＝[(ΔL*)2+(Δa*)2+(Δb*)2]1/2。
例如，当0≤ΔEab≤5时，两个彩色样品之间的颜色差异表现在盖板140表面时，该色差属于盖板140表面装饰效果可接受的范围。进一步地，当0≤ΔEab≤2时，两个彩色样品之间的颜色差异表现在盖板140表面时，该色差在肉眼条件下进行观察时几乎不可见，从而使得盖板140表面的“整体性和一体化”效果更好。
可选地，贴纸1410为塑胶材料件。塑胶材料的成本低，可以降低贴纸1410的成本。
根据本申请的一些进一步实施例，参照图1、图3-图6，盖板140还具有第二透光部142，第二透光部142与红外灯120相对，第二透光部142上设有第二涂层1421，第二涂层1421被构造成允许红外光线穿透且阻止可见光穿透。由此，红外灯120发射的红外光线可以穿透第二涂层1421照射入人眼400，同时在虹膜识别组件100温度升高、红外光产生漂移时，可以有效地避免可见光穿透第二透光部142，从而可以有效地避免虹膜识别光源可见，提高了虹膜识别组件100的识别效率和使用舒适性。
具体地，第二涂层1421电镀或丝印在第二透光部142上。也就是说，第二涂层1421可以通过电镀工艺电镀在第二透光部142上，也可以通过丝印工艺印在第二透光部142上。例如，第二涂层1421可以电镀或者丝印在第二透光部142的邻近红外灯120的一侧表面上。由此，可以将第二涂层1421牢靠地设置在第二透光部142上，提高了第二涂层1421的稳定性和可靠性且工艺简单，加工方便，有利于降低加工成本。
可选地，第二涂层1421为氧化硅氧化钛镀层，但不限于此。由此，可以保证红外灯120发射的红外光线穿透第二透光部142被人眼400接收，且可以阻止可见光穿透第二透光部142，从而可以保证虹膜识别光源不可见。同时，在使用过程中，氧化硅氧化钛镀层可以保证波长范围900nm以上的红外光线全部穿透第二透光部142，波长为800nm～900nm的红外光线少量穿透，800nm以下的光线完全不可以穿透。
进一步地，第二涂层1421的颜色与盖板140在第二透光部142周围的颜色具有一致性。参照图2和7，盖板140的非显示区域B区的颜色具有一致性。由此，可以进一步地提高电子装置300的美观度。
可选地，红外灯120发射的红外光线的波长范围为900nm～940nm(即900nm≤λ≤940nm)。其中，900nm～940nm的红外光在对虹膜成像提供有效光源的同时不被人眼400可见，用户体验更佳，且900nm～940nm的红外光对于黑色虹膜的识别效果更佳。由此，红外 灯120可以针对特定的亚洲人群使用，提高识别效率。
例如，在本申请的一个具体实施例中，红外灯120发射的红外光线的波长为940nm，其中，波长的公差范围可以为±20nm。940nm的红外光对于黑色虹膜的识别效果更佳。由此，红外灯120可以针对特定的亚洲人群使用，进一步地提高识别效率。
可选地，盖板140为玻璃盖板140。由此，可以提高提高电子装置300的显示效果且可以提升电子装置300的美观度。
根据本申请的一些进一步实施例，主板110上设有用于安装红外灯120的灯座121。灯座121具有第一安装面和第二安装面，灯座121的第一安装面与主板110相连且灯座121与虹膜摄像头130间隔开设置，例如，参照图3，红外灯120设在灯座121的第二安装面上，在由灯座121至虹膜摄像头130的方向上，灯座121的第二安装面朝向靠近主板110的方向延伸。
由于在由灯座121至虹膜摄像头130的方向上，灯座121的第二安装面朝向靠近主板110的方向延伸，将红外灯120安装在第二安装面后，可以使红外灯120的光轴朝向靠近虹膜摄像头130的方向发生偏转，从而可以使红外灯120发射的红外光线朝向靠近虹膜摄像头130的方向发生偏转。由此，当通过虹膜识别件对电子装置300进行解锁时，可以使人眼400对着虹膜摄像头130，红外灯120发射的红外光偏转一定的角度后被人眼400接收，从而可以将更多的红外光射入人眼400内，增加了人眼400接收的红外光，进而增加了虹膜摄像头130在人眼400上捕捉到的红外光，提高了虹膜识别效率和解锁成功率。
同时，本申请中的虹膜识别组件100通过在主板110上设置灯座121的方式，将红外灯120倾斜地在安装在主板110上，使得红外灯120在安装在主板110上时其光轴就偏转一定的角度，进而实现红外光的偏转。因此，本申请的红外灯120可以是普通的红外灯120，红外灯120本身不具有偏转功能，不需要特别定制，当虹膜摄像头130与红外灯120之间的距离发生改变时，可以通过调整槽底壁与第一表面111之间的夹角调整红外光线偏转的角度，从而缩短了虹膜识别组件100的制造周期，降低了制造成本，还可以实现红外灯120的共通化。
此外，相对于相关技术中通过提高红外灯120的电流增强红外光强度的技术方案，本申请中的虹膜识别组件100可以有效地避免因增大电流引起的发热问题，可以有效地改善电子装置300的散热问题，并能提高电子装置300的续航能力。
根据本申请的一些实施例，灯座121的第二安装面形成为平面结构。参照图3，灯座121的第二安装面形成为倾斜延伸的斜面。由此，可以方便地将红外灯120安装在灯座121上，提高了装配效率。
根据本申请的一些实施例，灯座121的第二安装面与第一安装面的夹角为α，α满足： 3°≤α≤10°。可以理解的是，第二安装面与第一安装面之间的夹角可以根据虹膜识别组件100的规格型号调整设计。例如，α可以进一步满足：4°≤α≤8°。具体地，当虹膜摄像头130与红外灯120之间的距离发生改变时，可以通过调整第二安装面与第一安装面1之间的夹角调整红外光线偏转的角度，制造周期短且成本低。
可选地，灯座121的截面形状为三角形或梯形。结构简单，加工方便。这里需要说明的是，在本申请中，灯座121的截面指的是与红外灯120的光轴平行的平面截该灯座121所得的平面。
在本申请的另一些实施例中，主板110的第一表面111上设有第一安装槽112，第一安装槽112与虹膜摄像头130间隔开设置，且在由第一安装槽112至虹膜摄像头130的方向上，第一安装槽112的槽底壁朝向远离第一表面111的方向延伸。红外灯120设在第一安装槽112内。
参照图4，红外灯120可以嵌设在第一安装槽112内，红外灯120可以与第一安装槽112的槽底壁相连。例如，红外灯120可以焊接在第一安装槽112的槽底壁上。结构简单，安装方便。
由于在由第一安装槽112至虹膜摄像头130的方向上，第一安装槽112的槽底壁朝向远离第一表面111的方向延伸，将红外灯120安装在第一安装槽112内后，可以使红外灯120的光轴朝向靠近虹膜摄像头130的方向发生偏转，从而可以使红外灯120发射的红外光线朝向靠近虹膜摄像头130的方向发生偏转。由此，当通过虹膜识别件对电子装置300进行解锁时，可以使人眼400对着虹膜摄像头130，红外灯120发射的红外光偏转一定的角度后被人眼400接收，从而可以将更多的红外光射入人眼400内，增加了人眼400接收的红外光，进而增加了虹膜摄像头130在人眼400上捕捉到的红外光，提高了虹膜识别效率和解锁成功率。
同时，本实施例中的虹膜识别组件100通过在主板110上设置第一安装槽112的方式，将红外灯120以倾斜地在安装在主板110上，使得红外灯120在安装在主板110上时其光轴就偏转一定的角度，进而实现红外光的偏转。因此，本申请的红外灯120可以是普通的红外灯120，红外灯120本身不具有偏转功能，不需要特别定制，当虹膜摄像头130与红外灯120之间的距离发生改变时，可以通过调整槽底壁与第一表面111之间的夹角调整红外光线偏转的角度，从而缩短了虹膜识别组件100的制造周期，降低了制造成本，且有利于减小电子装置300的整体厚度。
此外，相对于相关技术中通过提高红外灯120的电流增强红外光强度的技术方案，本申请中的虹膜识别组件100可以有效地避免因增大电流引起的发热问题，可以有效地改善电子装置300的散热问题，并能提高电子装置300的续航能力。
在本申请的再一些实施例中，主板110上设有安装座131，安装座131具有第三安装面和第四安装面，安装座131的第三安装面与主板110相连且安装座131与红外灯120间隔开设置，例如，参照图5，安装座131与红外灯120在左右方向上间隔开设置。在由安装座131至红外灯120的方向上，安装座131的第四安装面朝向靠近主板110的方向延伸。
虹膜摄像头130设在安装座131的第四安装面上。由于在由安装座131至红外灯120的方向上，安装座131的第四安装面朝向靠近主板110的方向延伸，将虹膜摄像头130安装在第四安装面后，可以使虹膜摄像头130的光轴朝向靠近红外灯120的方向发生偏转，从而可以改变虹膜摄像头130接收红外光线的方向。由此，当通过虹膜识别组件100对电子装置300进行解锁时，可以使人眼400对着红外灯120，红外灯120发射的红外光线直接照射到人眼400，虹膜摄像头130捕捉人眼400反射后的红外光线实现解锁，从而可以在不改变红外灯120发射的红外光线的方向的情况下，增加虹膜摄像头130在人眼400上捕捉到的红外光，提高了虹膜识别效率和解锁成功率。
同时，本实施例的虹膜识别组件100通过在主板110上设置安装座131的方式，将虹膜摄像头130倾斜地在安装在主板110上，改变了虹膜摄像头130的接收方向，因此，本实施例的红外灯120无需具有偏转功能，可以是普通的红外灯120，不需要特别定制，当虹膜摄像头130与红外灯120之间的距离发生改变时，可以通过改变第四安装面的延伸方向调整虹膜摄像头130的接收方向，从而缩短了虹膜识别组件100的制造周期，降低了制造成本。此外，相对于相关技术中通过提高红外灯120的电流增强红外光强度的技术方案，本申请中的虹膜识别组件100可以有效地避免因增大电流引起的发热问题，可以有效地改善电子装置300的散热问题，并能提高电子装置300的续航能力。
在本申请的又一些实施例中，主板110的第一表面111上设有第二安装槽113，第二安装槽113与红外灯120间隔开设置，且在由第二安装槽113至红外灯120的方向上，第二安装槽113的槽底壁朝向远离第一表面111的方向延伸。虹膜摄像头130设在第二安装槽113内。
参照图6，虹膜摄像头130可以嵌设在第二安装槽113内，虹膜摄像头130可以与第二安装槽113的槽底壁相连。例如，虹膜摄像头130可以焊接在第二安装槽113的槽底壁上。结构简单，安装方便。
由于在由第二安装槽113至红外灯120的方向上，第二安装槽113的槽底壁朝向远离第一表面111的方向延伸，将虹膜摄像头130安装在第二安装槽113内后，可以使虹膜摄像头130的光轴朝向靠近虹膜摄像头130的方向发生偏转，从而可以改变虹膜摄像头130接收红外光线的方向。由此，当通过虹膜识别件对电子装置300进行解锁时，可以使人眼400对着红外灯120，红外灯120发射的红外光线直接照射到人眼400，虹膜摄像头130捕 捉人眼400反射后的红外光线实现解锁，从而可以在不改变红外灯120发射的红外光线的方向的情况下，增加虹膜摄像头130在人眼400上捕捉到的红外光，提高了虹膜识别效率和解锁成功率。
同时，本实施例中的虹膜识别组件100通过在主板110上设置第二安装槽113的方式，将虹膜摄像头130倾斜地在安装在主板110上，改变了虹膜摄像头130的接收方向，因此，本实施例的红外灯120无需具有偏转功能，可以是普通的红外灯120，不需要特别定制，当虹膜摄像头130与红外灯120之间的距离发生改变时，可以通过调整槽底壁的延伸方向调整虹膜摄像头130的接收方向，从而缩短了虹膜识别组件100的制造周期，降低了制造成本且有利于减小电子装置300的整体厚度。
此外，相对于相关技术中通过提高红外灯120的电流增强红外光强度的技术方案，本实施例中的虹膜识别组件100可以有效地避免因增大电流引起的发热问题，可以有效地改善电子装置300的散热问题，并能提高电子装置300的续航能力。

下面以手机为例描述虹膜识别组件100唤醒手机的方法：
手机静止，虹膜摄像头130、红外灯120灯睡眠状态，不工作，重力传感器(gsensor) 工作，功耗很低；
实时监测手机的状态；
抬起模型，手机z方向朝上方向产生加速度，加速度值大于阈值，设置加速度阈值，比如2；
同时，可以通过陀螺仪监测手机旋转角度，设置旋转角度阈值，比如30度；
如果同时超过两者阈值，认为手机此时被拿起，并且是屏幕朝向用户面部的。
step1：通过重力传感器gsensor和陀螺仪数据检测到手机抬起的动作；
step2：同时通过接近传感器，如果检测到手机没有物体遮挡；
step3：马上自动开始虹膜摄像头130、红外灯120，开始进行虹膜识别。
这样，用户在抬起的过程中，虹膜摄像头130和红外灯120已经开启工作了，这时候，用户不需要手按power键来亮屏再识别。
