请一并参阅图1及图2，图1为本申请一实施例中的电子装置100的在一视角的示意出部分结构的平面示意图。图2为本申请一实施例中的电子装置100在图1所示视角的示意出部分结构的分解示意图。所述电子装置100包括壳体1，所述壳体1包括边框2以及设置于所述边框2上的导光结构3。

从而，本申请中，通过在壳体1的边框2上设置导光结构3，而将发光光源4的光线从边框2上的导光结构3导出，可以通过边框进行发光，无需在电子装置100的前屏开设指示灯孔，可有效地提升屏占比。此外，通过在导光膜32的上设置凸起入光部R1，光线从凸起入光部R1进入后朝导光膜32其他区域发射时会逐渐减弱，而呈现了发光亮度渐变的效果，提升了发光的显示效果。
其中，所述未与所述透明装饰件31贴合的面F0指的是与所述导光膜32和所述透明装饰件31贴合的面的相对的面。
在一些实施例中，所述凸起入光部R1为设置于所述导光膜32的面F0上的非端部位置，从而，光线从凸起入光部R1进入后朝导光膜32的凸起入光部R1的两侧发射时逐渐减弱，而呈现了发光亮度从凸起入光部R1向两边渐变的效果。
请一并参阅图3，为所述导光膜32的结构示意图。在一些实施例中，如图2及图3所示，所述导光膜32包括第一导光膜部301和第二导光膜部302，所述第一导光膜部301包括第一本体310和从第一本体310的第一端部D1弯折形成的第一弯折部B1，所述第二导光膜部302包括第二本体320和从第二本体320的第二端部D2弯折形成的第二弯折部B2，所述第一弯折部B1和第二弯折部B2贴合在一起形成所述凸起入光部R1。从而，发光光源4的光线从所述凸起入光部R1导入后分别沿第一导光膜部301的第一本体310和第二导光膜部302的第二本体320的方向导至所述透明装饰件31，并通过所述透明装饰件31导出。
其中，所述透明装饰件31位于所述边框2的最外侧，起到外观装饰面和出光面的效果。
其中，如图2或图3所示，在一些实施例中，所述第一导光膜部301和第二导光膜部302为对称结构，即，所述第一本体310和第二本体320对称，所述第一弯折部B1和第二弯折部B2对称。所述第一弯折部B1和第二弯折部B2贴合形成的凸起入光部R1位于所述导光膜32的中部位置。

请参阅图4，为另一实施例中的导光膜32的侧面示意图。在另一实施例中，所述导光膜32的凸起入光部R1可为从所述导光膜32的未与所述透明装饰件31贴合的面F0的非端部位置垂直延伸形成的柱状结构，例如扁平柱状结 构。其中，所述凸起入光部R1与所述导光膜32可一体成型，或者所述凸起入光部R1为与所述导光膜32的面F0的非端部位置通过光学胶等透明胶水粘接。
在一些实施例中，如图2-4所示，所述非端部位置为所述导光膜32的面F0上的中部位置等。
请参阅图5，为再一实施例中的导光膜32的侧面示意图。在再一实施例中，所述凸起入光部R1也可以设置于所述导光膜32的面F0上的端部位置，从而光线从凸起入光部R1进入后朝导光膜32的另一端发射时逐渐减弱，而呈现了发光亮度从一端到另一端逐渐变化的发光亮度渐变效果。
请返回参考图2，如图2所示，所述导光结构3还包括光学胶层33，所述透明装饰件31和所述导光膜32通过所述光学胶层33固定在一起。其中，所述光学胶层33为OCR(optically clear adhesive，光学透明粘接剂)光学胶层。
在一些实施例中，所述透明装饰件31和所述导光膜32通过所述光学胶层33紧密固定在一起而形成一个透明的装饰件组件。显然，在其他实施例中，所述透明装饰件31和所述导光膜32也可以通过局部点胶的方式紧密固定在一起，或者通过整体涂覆其他透明胶水等方式紧密固定在一起。在一些实施例中，所述透明装饰件31和所述导光膜32也可通过卡合结构卡合固定在一起，例如，透明装饰件31上设置有若干凸起，导光膜32上设置有若干与所述凸起配合的凹槽，通过凸起与凹槽的配合而将透明装饰件31和所述导光膜32卡合固定在一起。
如图2所示，其中，当所述导光膜32包括第一导光膜部301和第二导光膜部302时，所述第一导光膜部301的第一本体310以及所述第二导光膜部302的第二本体320通过所述光学胶层33固定于透明装饰件31上。从而，通过所述光学胶层33，可实现导光膜32和透明装饰件31之间的紧密固定，同时还可实现所述第一导光膜部301和第二导光膜部302之间的位置结构关系的相对固定。
在一些实施例中，所述第一导光膜部301的第一弯折部B1和所述第二导光膜部302的第二弯折部B2之间还可通过光学胶等透明胶水粘接贴合，而增强结构的稳定性。

显然，所述透明装饰件31或所述导光膜32也可为透明玻璃、透明树脂、透明塑料等中的任一种材料制成。
其中，如图2所示，所述导光结构3还包括遮光胶34，所述遮光胶34贴合于所述导光膜32的未与所述透明装饰件贴合的面F0上的未设置所述凸起入光部R1的位置。
所述遮光胶34包括第一遮光胶部341和第二遮光胶部343，在一些实施例中，当所述导光膜32包括第一导光膜部301和第二导光膜部302时，所述第一遮光胶部贴合于所述第一导光膜部301的第一本体310未与所述透明装饰件31贴合的面F0上，所述第二遮光胶部343贴合于所述第二导光膜部302的第二本体320未与所述透明装饰件31贴合的面F0上，所述凸起入光部R1从所述第一遮光胶部341和第二遮光胶部343之间的间隙J1穿过而延伸至所述遮光胶34之外。
所述遮光胶34用于进行遮光，而仅允许发光光源4的光线从所述凸起入光部R1导入所述导光膜32，并从所述导光膜32的凸起入光部R1处发散至导光膜32的其他区域，从而保证了发光亮度渐变的效果。
在一些实施例中，所述遮光胶34为黑色或白色双面遮光胶。
所述导光结构3通过所述遮光胶34粘接固定于所述边框2上。
请参阅图6，为一些实施例中的导光膜32的俯视示意图。如图4所示，在一些实施例中，所述导光膜32的未设置所述凸起入光部R1的至少部分区域还进行了穿孔处理，而形成了若干穿孔K0，所述若干穿孔K0构成网状孔。从而，光线通过所述导光膜32进行传输时，通过所述若干穿孔K0进行反射和折射，增强了光线的发散度，提升了导光膜32的导光效果。
其中，所述若干穿孔K0的尺寸远小于导光膜32的尺寸，例如穿孔K0的直径小于导光膜31的任一方向上的长度的1/10。其中，所述若干穿孔K0可为规则排列，例如为矩阵式排列。在一些实施例中，所述若干穿孔K0可为杂乱排列。
显然，当所述导光膜32包括第一导光膜部301和第二导光膜部302时，所述若干穿孔K0位于所述第一导光膜部301的第一本体310以及所述第二导光膜部302的第二本体320上。
其中，如图6所示，所述凸起入光部R1可为位于导光膜32的长边的中部位置，且延伸于所述导光膜32的两个窄边之间。
