具体实施方式
下面,将参考附图详细地描述根据本申请的示例实施例。显然,所描述的实施例仅仅是本申请的一部分实施例,而不是本申请的全部实施例,应理解,本申请不受这里描述的示例实施例的限制。
申请概述
如上所述,为了满足越来越广泛的市场需求,高像素、大芯片、小尺寸、大光圈是现有摄像模组不可逆转的发展趋势,随着感光芯片的尺寸逐步提升,与其匹配的滤光元件尺寸也需增加。滤光元件为敏感且脆弱的元器件,随着其尺寸的增大,其敏感性和脆弱度将进一步增加。在实际产业应用中,已出现多个在滤光元件尺寸增大之后带来的问题,例如,滤光元件更易破损甚至破裂、滤光元件相对感光芯片发生倾斜等。
在摄像模组(例如,常规摄像模组、潜望式摄像模组、指纹模组、TOF深度信息摄像模组)中,滤光元件71P具有重要的滤光、防杂散光的作用, 随着其面积尺寸的增加,并且摄像模组小型化的需求也限制着其厚度尺寸,也就是,滤光元件71P的面积逐渐增大,同时,其厚度尺寸有变小的趋势,因此,滤光元件71P的面积与厚度的比值将增大。在物理表现上,面积与厚度的比值增大的滤光元件71P更易发生形变,也更加脆弱。
由于用于承载滤光元件71P的支架72P与滤光元件71P之间的热膨胀系数(Coefficient of thermal expansion,CTE)相差过大,在环境温度发生变化时,因支架72P形变产生的应力将作用于滤光元件71P,当滤光元件71P所受应力超过预定阈值而导致其发生的形变量超过预定阈值时,滤光元件71P将发生破损甚至破裂,经试验测试,发生破损甚至破裂的形变量的预设阈值为4000μe,即,当发生的形变量超过4000μe时,滤光元件71P将发生破损甚至破裂。并且,本领域普通技术人员应知晓,在生产过程中,滤光元件71P自身存在微裂纹,这些微裂纹会使得应力集中,增大破损或破裂的几率。
并且,由于支架72P的热膨胀系数较大,在环境温度变化较大的情况下,支架72P自身产生的形变往往是不均匀的,导致支架72P上表面用于支撑滤光元件71P的部分的形变高低不平,也就是,支架72P中用于安装滤光元件71P部分的平面因不均匀的形变会产生高度差,而导致滤光元件71P相对于感光芯片发生倾斜,如图1所示。图1图示了现有的摄像模组中滤光元件71P相对感光芯片发生倾斜的示意图。倾斜安装的滤光元件71P会引起成像系统焦距的变化而产生像移。并且,滤光倾斜,还会导致外界光线入射到滤光元件71P时的入射角度相较于理想情况存在差距,容易导致杂散光的增加。并且,支架72P表面高低不平导致滤光元件71P的支撑面积减小,增大了滤光元件71P发生破损的风险。
针对上述技术问题,本申请的基本构思是通过在摄像模组中的滤光元件及其支撑部分之间设置介质层,来避免所述滤光元件因自身的形变而导致破损和摄像模组成像质量的降低。
基于此,本申请提出了一种感光组件,其包括:滤光元件、用于承载所述滤光元件的支架,以及,介质层,其中,所述介质层被设置于所述线路板和所述感光芯片之间,具有用于防止所述滤光元件所发生的形变量超过预定阈值的预定柔性。这样,通过在摄像模组中的滤光元件及其支撑部分之间设置介质层,来避免所述滤光元件因其支撑部分的形变产生的应力集中于所述滤光元件而导致所述滤光元件所产生的形变量超过预定阈值,而导致所述滤 光元件破损以及摄像模组成像质量的降低。
在介绍本申请的基本原理之后,下面将参考附图来具体介绍本申请的各种非限制性实施例。
实施例一
图2图示了根据本申请实施例的光学组件的示意图。在如图2所示意的光学组件中,所述光学组件710,包括一滤光元件711、介质层712和一支架713,所述滤光元件711通过所述介质层712被安装于所述支架713,所述介质层712可以有效地吸收因所述支架713形变而产生的作用于所述滤光元件711的应力,从而避免所述滤光元件711因其支撑部分的形变产生的应力集中于所述滤光元件711而导致所述滤光元件711所产生的形变量超过预定阈值,进而导致所述滤光元件711发生破损。如上所述,该预设阈值为4000μe。也就是说,即使该光学组件710的所述支架713在升温或降温过程中发生形变或者外部应力作用于所述支架而导致其发生变形,所述介质层712也会确保所述滤光元件711的稳定性。
进一步地,在本申请实施例中,所述介质层712优选地被实施为柔性材料,其具有用于防止所述滤光元件711所发生的形变量超过预定阈值的预定柔性,也就是,所述滤光元件711的预定柔性并非某个特定值,其仅需能够防止所述滤光元件因受应力所产生的形变量低于4000μe即可。特别地,在本申请实施中,该柔性材料的邵氏硬度可选择为10HSA-70HSA,例如,20HSA、30HSA,其受到外力可以压缩自身厚度的5%~50%(优选地,30%~50%),或者,拉伸自身厚度的5%~50%(优选地,30%~50%),其中,10HSA表示用A型邵氏硬度计测定的邵氏硬度值为10,70HSA,20HSA,30HSA同理可知。并且,在本申请实施例中,所述介质层712的上表面对应于所述滤光元件711,其下表面对应于所述支架713,当环境温度发生变化或者外部应力作用于所述支架导致所述支架713发生形变,支架713形变的力会带动所述介质层712的下表面形变。由于所述介质层712可以压缩自身厚度的5%~50%(优选地,30%~50%),或者,拉伸自身厚度的5%~50%(优选地,30%~50%),那么其上表面则不会发生弯曲,依旧是接近平面,支架713形变的力也不会作用至所述滤光元件711,如图3所示,因此,所述滤光元件711的感光面可以保持较好的平面度,可以减少光线发散,这里,所 述滤光元件711的感光面的平面度可以是0.701λ-0.72λ(λ为光波长符号),或者说,所述滤光元件711的感光面的平面度在0.716um以下。也可以理解为,所述滤光元件711的硬度比所述介质层712的大,故可以通过所述介质层712的形变来抑制所述滤光元件711的形变(弯曲)。
进一步地,在本申请实施例中,所述介质层712的制成材料可被实施为泡棉、PET(聚对苯二甲酸乙二醇酯,塑料材料的一种)+PU(PU为泡棉)、软胶、硅胶等,其中,PET+PU可以理解为在PET材料上发泡形成PU层,其中,PET也可以被实施为其他塑料材料,甚至,PET可以用金属取代,即在金属上发泡形成PU层。
如图2所示,在本申请实施例中,所述光学组件710进一步包括至少一粘接件714,所述介质层712通过所述粘接件714分别与所述支架713和所述滤光元件711连接,所述粘接件714可以被实施为胶水、双面胶等具有粘性的粘接工具。也就是说,在本申请实施例中,先在所述介质层712、所述滤光元件711或所述支架713上设置所述粘接件714,再通过所述粘接件714将所述介质层712、所述支架713和所述滤光元件711固定以形成所述光学组件710。
特别地,当所述介质层712为泡棉时,所述泡棉厚度为80~130um,优选地为100um,此时,所述滤光元件711的厚度为0.715~2.75mm,优选地为1~2mm;所述粘接件714的厚度为20um~40um。当所述介质层712被实施为软胶时,所述软胶厚度为20~100um,优选为50um,此时,所述滤光元件711的厚度为0.715~2.75mm,优选为1mm~2mm。
在上述实施例的一个变形实施例中,所述介质层712可以与所述支架713一体形成,即,所述介质层712和所述支架713为一体结构。例如,所述介质层712可以通过镀膜、喷涂、印刷、发泡等工艺形成于所述支架713。比如,当所述介质层712为泡棉层时,可以通过在所述支架713上预设材料,经发泡形成所述介质层712。这样,所述泡棉层(即,所述介质层712)无需通过所述粘接件714与所述支架713固定,可进一步有效控制所述粘接件714带来的误差,有利于提升所述光学组件710的精度。值得一提的是,在该变形实施例中,所述介质层712参数、性能与上述实施例相同或相近。
也就是说,在该变形实施例中,所述光学组件710的制备过程可以是:先在所述支架713上形成所述介质层712,再通过所述粘接件714将所述滤 光元件711与所述介质层712固定,以形成所述光学组件710。
在上述实施例的另一个变形实施例中,所述介质层712与所述滤光元件711一体形成,即,所述介质层712与所述滤光元件711具有一体结构,例如,所述介质层712可以通过镀膜、喷涂、印刷、发泡等工艺形成于所述滤光元件711。
进一步地,如图2所示,在本申请实施例中,所述支架713包括支撑部7131和自所述支撑部7131向内延伸的悬持部7132,所述滤光元件711被安装于所述悬持部7132。为了保护所述滤光元件,优选地,所述支撑部7131的上表面高于所述悬持部7132的上表面高度,也就是,所述悬持部7132和所述支撑部7131之间具有落差,以形成用于收容所述滤光元件711的保护腔。更优选地,当所述滤光元件711被贴装于所述保护腔内时,所述滤光元件711的上表面低于所述支撑部7131的上表面。
值得一提的是,在本申请实施例中,所述滤光元件711可以被实施为各种类型滤光元件,包括但不限于红外截止滤光片、全透光谱滤光片以及其他的滤光片或者多个滤光片的组合。具体来说,例如,当所述滤光元件711被实施为红外截止滤光片和全透光谱滤光片的组合,即,所述红外截止滤光片和所述全透光谱滤片能够被切换以选择性地位于所述滤光元件711的感光路径上,这样,在白天等光线较为充足的环境下使用时,可以将所述红外截止滤光片切换至所述滤光元件711的感光路径,以藉由所述红外截止滤光片过滤进入所述滤光元件711的被物体反射的光线中的红外线,并且,当夜晚等光线较暗的环境中使用时,可以将所述全透光谱滤光片切换至所述滤光元件711的感光路径,以允许进入所述滤光元件711的被物体反射的光线中的红外线部分透光。
实施例二
如图4所示,在该实施例中,所述光学组件710由所述滤光元件711、所述粘接件714和所述支架713构成,其中,所述粘接件714的厚度为50um-100um(包括等于50um和等于100um)。也就是,在该实施中,所述粘接件714的作用相当于实施例71中的所述介质层712和所述粘接件714的二合一,或者说,实施例71中的所述介质层712被实施为由厚度为50um-100um的黏着剂固化形成。值得一提的是,现有粘接件例如胶水由于 具有流动性,其无法在所述滤光元件711或支架713上施加厚度为50um-100um的胶水,故在该实施例中,进一步提供支撑件715,所述支撑件715被设置于所述支架713,所述支撑件715与所述支架713的上表面形成一收容腔7150,所述粘接件714(胶水)被设置于所述收容腔7150内,再将所述滤光元件711贴附于所述粘接件714,然后,通过烘烤等工艺使得所述粘接件714固化,以形成所述光学组件710。如图4所示,在该实施例中,所述支撑件715包括内支撑单元7151和外支撑单元7152,所述收容腔7150形成于所述支撑表面,所述内支撑单元7151的内侧面和所述外支撑单元7152的内侧面之间,并且,所述内支撑单元7151和所述外支撑单元7152都具有环形结构。值得一提的是,在该实施例中,所述外支撑单元7152的高度高于所述内支撑单元7151的高度,当然,所述内支撑单元7151和所述外支撑单元7152的高度也可以相等,对此,并不为本申请所局限。
在该实施例中,所述粘接件714优选为胶水,该胶水具有一定柔性,这里,在固化成所述粘接件714后依旧具有一定的柔性。所述粘接件714的上表面对向所述滤光元件711,其下表面对向所述支架713,当环境温度变化导致所述支架713发生形变,所述支架713形变的力带动所述粘接件714的下表面形变,由于所述粘接件714具有一定柔性且具有50um-100um的厚度,那么其上表面则不会受到影响而发生弯曲,依旧是接近平面,所述支架713形变的力也不会作用至所述滤光元件711,因此,所述滤光元件711可以保持较好的平面度。
进一步地,在该实施例中,所述粘接件714具有较大的形变能力,具体地,所述粘接件714受到外力可以压缩自身厚度的5%~50%(优选地,30%~50%),或者,拉伸自身厚度的5%~50%(优选地,30%~50%)。相应地,当环境温度发生变化导致所述支架713发生形变,支架713形变的力会带动所述粘接件714的下表面形变,由于所述介质层712可以压缩自身厚度的5%~50%(优选地,30%~50%),或者,拉伸自身厚度的5%~50%(优选地,30%~50%),那么其上表面则不会发生弯曲,依旧是接近平面,支架713形变的力也不会作用至所述滤光元件711,因此,所述滤光元件711的反射面可以保持较好的平面度,可以减少光线发散。
值得一提的是,在本申请实施例中,所述粘接件714的厚度低于所述支撑件715的高度。也就是说,在制备过程中,胶水的厚度小于所述支撑件715 的高度,以使得胶水被完全收容于所述收容腔7150内,同时,所述滤光元件711也被收容于所述收容腔7150内。
在上述实施例的变形实施例中,所述胶水的厚度也可以大于或者等于所述支撑件715的高度。如图5所示,在该变形实施例中,所述粘接件714(胶水)的厚度大于所述支撑件715的高度,应可以理解,由于胶水具有一定粘稠度,因此,在制备过程中,即使胶水厚度与所述支撑件715的高度差在一定范围内,胶水也不会自所述收容腔7150内溢出。
还值得一提的是,在上述实施例的其他变形实施例中,所述支撑件715在所述胶水固化形成所述粘接件714后也可以选择去除,即,所述光学组件710不包括所述支撑件715,如图6所示
实施例三
上述实施例一和实施例二公开的光学组件可以应用于摄像模组,例如,常规的摄像模组、潜望式摄像模组、TOF深度信息摄像模组等。图7图示了根据本申请实施例的摄像模组的示意图。如图7所示,所述摄像模组,包括:感光组件720和保持于所述光学组件720的感光路径上的光学镜头730,其中,所述感光组件720包括实施例71和实施例72公开的光学组件710。
如图7所示,在本申请实施例中,所述感光组件进一步包括线路板721、电连接于所述线路板721的感光芯片722和设置于所述线路板721的至少一电子元器件723,其中,所述光学组件710设置于所述线路板721。更具体地,所述光学组件710的所述支架713被贴装于所述线路板721上,所述滤光元件711位于所述感光芯片722的感光路径。
图8图示了根据本申请实施例的所述摄像模组的一个变形实施例的示意图。如图8所示,在该变形实施例中,所述摄像模组进一步设置于所述线路板的底座724,所述光学组件710被安装于所述底座724。也就是,在该变形实施例中,所述光学组件710的安装方式发生改变。特别地,在变形实施例中,所述底座724为通过模塑工艺一体成型于所述线路板721的模塑底座,当然,在本申请其他示例中,所述底座724还可以被实施为其他类型的底座,以及,所述底座724一体成型于所述线路板的位置可发生调整。
值得一提的是,所述摄像模组进一步可被应用于电子设备,例如,智能手机、平板电脑等,以作为所述电子设备的前置摄像模组或者后置摄像模组。

申请概述
如上所述,随着消费者对终端设备的成像质量要求越来越高,摄像模组所采集的感光芯片尺寸也逐渐增大,这引发了一系列技术问题。并且,这些技术问题在现有的摄像模组结构中得不到妥善解决。因此,需要改进的摄像模组结构及其制造方案以生产满足性能要求的感光组件、摄像模组、电子设备和感光组件的制备方法。
具体来说,在现有的摄像模组中,感光芯片81P常通过COB(Chip on Board)工艺贴附于线路板82P的上表面,即,通过粘着剂将感光芯片81P贴附于感光芯片81P的上表面。通常,感光芯片81P与线路板82P之间的热膨胀系数(Coefficient of thermal expansion,CTE)相差过大,因此,在工作过程中,受环境温度变化的影响,线路板82P会发生形变而导致感光芯片81P发生形变,具体的形变形态为:感光芯片81P朝向光学镜头侧弯曲,以形成类似于“哭脸”的形状,如图9所示。图9图示了现有的摄像模组中感光芯片81P的弯曲示意图。
本领域技术人员应知晓,即便感光芯片81P没有发生“哭脸”状形变,由于感光芯片81P的边缘区域和中心区域相对于光学镜头的光程差不同,导致光心在抵达感光芯片81P的边缘部分时,容易出现畸变、边角失光以及锐角下降等不良现象,导致成像效果变差。在发生“哭脸”状形变之后,不良的成像现象会进一步地加剧,更为严重地影响了成像质量。具体来说,如图9所示,在摄像模组的成像过程中,实际焦点平面形成朝向线路板82P侧凸起的弧形,也就是,实际焦点平面为弧形面。应可以看出,“哭脸”状的形变恰好与实际焦点平面的形变方式相反,导致畸变、边角失光以及锐角下降等不良现象的程度被加剧,更为严重地影响摄像模组的成像质量。
针对上述技术问题,本申请的基本构思是通过在摄像模组中的感光芯片及其支撑部分之间设置介质层,来避免因感光芯片形变而导致的成像质量的降低。
基于此,本申请提出了一种感光组件,其包括:线路板;电连接于所述线路板的感光芯片;以及,介质层,所述介质层被设置于所述线路板和所述感光芯片之间,具有用于防止所述感光芯片形变的预定柔性。这样,通过在摄像模组中的感光芯片和线路板之间设置介质层,来避免因感光芯片形变而导致的成像质量的降低。在介绍本申请的基本原理之后,下面将参考附图来具体介绍本申请的各种非限制性实施例。
实施例一
图10图示了根据本申请实施例的感光组件的示意图。在如图10所示意的感光组件中,所述感光组件810,包括一感光芯片811、介质层812和一线路板813,所述感光芯片811通过所述介质层812被安装于所述线路板813,所述感光芯片811通过诸如引线之类的电连接介质被可导通地连接于所述线路板,其中,所述介质层812可以有效地防止所述感光芯片811弯曲。也就是说,即使该感光组件810的所述线路板813在升温或降温过程中发生形变,所述介质层812也会确保所述感光芯片811的稳定性。
进一步地,在本申请实施例中,所述介质层812优选地被实施为柔性材料,该柔性材料的邵氏硬度为10HSA-70HSA,例如,20HSA、30HSA,其受到外力可以压缩自身厚度的5%~50%(优选地,30%~50%),或者,拉伸自身厚度的5%~50%(优选地,30%~50%),其中,10HSA表示用A型邵氏硬度计测定的邵氏硬度值为10,70HSA,20HSA,30HSA同理可知。并且,在本申请实施例中,所述介质层812的上表面对应于所述感光芯片811,其下表面对应于所述线路板813,当环境温度发生变化导致所述线路板813发生形变,线路板813形变的力会带动所述介质层812的下表面形变。由于所述介质层812可以压缩自身厚度的5%~50%(优选地,30%~50%),或者,拉伸自身厚度的5%~50%(优选地,30%~50%),那么其上表面则不会发生弯曲,依旧是接近平面,线路板813形变的力也不会作用至所述感光芯片811,如图11所示,因此,所述感光芯片811的感光面可以保持较好的平面度,可以减少光线发散,这里,所述感光芯片811的感光面的平面度可以是0.801λ-0.82λ(λ为光波长符号),或者说,所述感光芯片811的感光面的平面度在0.816um以下。也可以理解为,所述感光芯片811的硬度比所述介质层812的大,故可以通过所述介质层812的形变来抑制所述感光芯片811的形 变(弯曲)。
进一步地,在本申请实施例中,所述介质层812的制成材料可被实施为泡棉、聚对苯二甲酸乙二醇酯(英文名:Polyethylene terephthalate,简称PET)+聚氨酯(英文名:Polyuretha,简称PU)、软胶、硅胶等,其中,PET+PU可以理解为在PET材料上发泡形成PU层,其中,PET也可以被实施为其他塑料材料,甚至,PET可以用金属取代,即在金属上发泡形成PU层。
如图10所示,在本申请实施例中,所述感光组件810进一步包括至少一粘接件814,所述介质层812通过所述粘接件814分别与所述线路板813和所述感光芯片811连接,所述粘接件814可以被实施为胶水、双面胶等具有粘性的粘接工具。也就是说,在本申请实施例中,先在所述介质层812、所述感光芯片811或所述线路板813上设置所述粘接件814,再通过所述粘接件814将所述介质层812、所述线路板813和所述感光芯片811固定以形成所述感光组件810。
特别地,当所述介质层812为泡棉时,所述泡棉厚度为80~130um,优选地为100um,此时,所述感光芯片811的厚度为0.815~2.85mm,优选地为1~2mm;所述粘接件814的厚度为20um~40um。当所述介质层812被实施为软胶时,所述软胶厚度厚度为20~100um,优选为50um,此时,所述感光芯片811的厚度为0.815~2.85mm,优选为1mm~2mm。
在上述实施例的一个变形实施例中,所述介质层812可以与所述线路板813一体形成,即,所述介质层812和所述线路板813为一体结构。例如,所述介质层812可以通过镀膜、喷涂、印刷、发泡等工艺形成于所述线路板813。比如,当所述介质层812为泡棉层时,可以通过在所述线路板813上预设材料,经发泡形成所述介质层812。这样,所述泡棉层(即,所述介质层812)无需通过所述粘接件814与所述线路板813固定,可进一步有效控制所述粘接件814带来的误差,有利于提升所述感光组件810的精度。值得一提的是,在该变形实施例中,所述介质层812参数、性能与上述实施例相同或相近。
也就是说,在该变形实施例中,所述感光组件810的制备过程可以是:先在所述线路板813上形成所述介质层812,再通过所述粘接件814将所述感光芯片811与所述介质层812固定,以形成所述感光组件810。
在上述实施例的另一个变形实施例中,所述介质层812与所述感光芯片 811一体形成,即,所述介质层812与所述感光芯片811具有一体结构,例如,所述介质层812可以通过镀膜、喷涂、印刷、发泡等工艺形成于所述感光芯片811。
实施例二
如图12所示,在该实施例中,所述感光组件810由所述感光芯片811、所述粘接件814和所述线路板813构成,其中,所述粘接件814的厚度为50um-100um(包括等于50um和等于100um)。也就是,在该实施中,所述粘接件814的作用相当于实施例81中的所述介质层812和所述粘接件814的二合一,或者说,实施例81中的所述介质层812被实施为由厚度为50um-100um的黏着剂固化形成。值得一提的是,现有粘接物例如胶水由于具有流动性,其无法在所述感光芯片811或线路板813上施加厚度为50um-100um的胶水,故在该实施例中,进一步提供支撑件815,所述支撑件815被设置为所述线路板813,所述支撑件815的内侧面与所述线路板813的上表面形成一收容腔8150,所述粘接件814(胶水)被设置于所述收容腔8150内,再将所述感光芯片811贴附于所述粘接件814,然后,通过烘烤等工艺使得所述粘接件814固化,以形成所述感光组件810。值得一提的是,在该实施例中,所述支撑件815的截面可被实施为环状或者类环状。
在该实施例中,所述粘接件814优选为胶水,该胶水具有一定柔性,这里,在固化成所述粘接件814后依旧具有一定的柔性。所述粘接件814的上表面对向所述感光芯片811,其下表面对向所述线路板813,当环境温度变化导致所述线路板813发生形变,所述线路板813形变的力带动所述粘接件814的下表面形变,由于所述粘接件814具有一定柔性且具有50um-100um的厚度,那么其上表面则不会受到影响而发生弯曲,依旧是接近平面,所述线路板813形变的力也不会作用至所述感光芯片811,因此,所述感光芯片811可以保持较好的平面度。
进一步地,在该实施例中,所述粘接件814具有较大的形变能力,具体地,所述粘接件814受到外力可以压缩自身厚度的5%~50%(优选地,30%~50%),或者,拉伸自身厚度的5%~50%(优选地,30%~50%)。相应地,当环境温度发生变化导致所述线路板813发生形变,线路板813形变的力会带动所述粘接件814的下表面形变,由于所述介质层812可以压缩自 身厚度的5%~50%(优选地,30%~50%),或者,拉伸自身厚度的5%~50%(优选地,30%~50%),那么其上表面则不会发生弯曲,依旧是接近平面,线路板813形变的力也不会作用至所述感光芯片811,因此,所述感光芯片811的反射面可以保持较好的平面度,可以减少光线发散。
值得一提的是,在本申请实施例中,所述粘接件814的厚度低于所述支撑件815的高度。也就是说,在制备过程中,胶水的厚度小于所述支撑件815的高度,以使得胶水被完全收容于所述收容腔8150内,同时,所述感光芯片811也被收容于所述收容腔8150内。
在上述实施例的变形实施例中,所述胶水的厚度也可以大于或者等于所述支撑件815的高度。如图13所示,在该变形实施例中,所述粘接件814(胶水)的厚度大于所述支撑件815的高度,应可以理解,由于胶水具有一定粘稠度,因此,在制备过程中,即使胶水厚度与所述支撑件815的高度差在一定范围内,胶水也不会自所述收容腔8150内溢出。
还值得一提的是,在上述实施例的其他变形实施例中,所述支撑件815在所述胶水固化形成所述粘接件814后也可以选择去除,即,所述感光组件810不包括所述支撑件815,如图14所示。
实施例三
上述实施例一和实施例二公开的感光组件可以应用于摄像模组,例如,常规的摄像模组、潜望式摄像模组、TOF深度信息摄像模组等。图15图示了根据本申请实施例的摄像模组的示意图。如图15所示,所述摄像模组,包括:如上所述的感光组件810和保持于所述感光组件810的感光路径上的光学镜头820。
应注意到,在本申请实施例中,所述感光组件810进一步包括设置于所述线路板813的至少一电子元器件816、设置于所述线路板813上的支架817,以及,安装于所述支架上的滤光元件818,所述至少一电子元器件,包括但不限于电容,电阻,电感。在本申请实施例中,所述支架817可被实施为传统的塑料支架817,其预制成型并贴附于所述线路板811的上表面,或者,所述支架817可被实施为模塑支架,其通过模塑工艺一体成型于所述线路板的上表面,对此,并不为本申请所局限。所述滤光元件818能够被实施为不同的类型,包括但不限于所述滤光元件818能够被实施为红外截止滤光片、 全透光谱滤光片以及其他的滤光片或者多个滤光片的组合。具体来说,例如,当所述滤光元件818被实施为红外截止滤光片和全透光谱滤光片的组合,即,所述红外截止滤光片和所述全透光谱滤片能够被切换以选择性地位于所述感光芯片811的感光路径上,这样,在白天等光线较为充足的环境下使用时,可以将所述红外截止滤光片切换至所述感光芯片811的感光路径,以藉由所述红外截止滤光片过滤进入所述感光芯片811的被物体反射的光线中的红外线,并且,当夜晚等光线较暗的环境中使用时,可以将所述全透光谱滤光片切换至所述感光芯片811的感光路径,以允许进入所述感光芯片811的被物体反射的光线中的红外线部分透光。
图16图示了根据本申请实施例的所述摄像模组的一个变形实施例的示意图。如图16所示,在该变形实施例中,所述摄像模组进一步包括设置于支架817或线路板813上的滤光元件支架819,所述滤光元件818被安装于所述滤光元件支架819,也就是,在该变形实施例中,所述滤光元件818的安装方式发生改变。

值得一提的是,在该实施例中,所述摄像模组8120可被实施为如上所述的普通型的摄像模组如图15和图16所示,或者其他类型的摄像模组,例如,TOF深度信息摄像模组。所述摄像模组810安装于所述电子设备主体8110的位置也并不为本申请所局限,例如,其可安装于所述电子设备主体8110的正面,以作为所述电子设备8100的前置摄像模组;或者,其可安装于所述电子设备主体8110的背面,以作为所述电子设备8100的后置摄像模组。
