Description

视窗及应用该视窗的电子装置
技术领域
本发明是关于一种视窗及应用该视窗的电子装置，尤其是关于一种具有镜面效果的视窗及应用该视窗的电子装置。
背景技术
现有电子产品(如手机、PDA等)的壳体常镀覆一金属层或具有金属效果的膜层而使产品外观具有金属光泽或金属镜面效果，从而吸引消费者眼球。然而随着消费者对美的追求越来越高，单一的仅壳体具有金属光泽的效果已不能满足消费者的需求。由于人们在使用电子产品时常接触的界面是视窗，若使电子产品的视窗亦具有金属光泽或金属镜面效果，则会大大提升产品的外观竞争力及附加价值。作为应用于电子产品的视窗，首先要满足不能屏蔽电磁波的条件，以保持产品的正常功能；且由于视窗为人机交流的界面，又要求其在使用状态时具有高透光性。然而在所述视窗上镀覆金属层或具金属效果的膜层时必定会降低视窗的透光性。如何使电子产品的视窗在不屏蔽电磁波的条件下，既具有金属镜面效果又具有高透光性，一直是电子产品制造界的一个挑战。
发明内容
鉴于此，有必要提供一种不屏蔽电磁波、且同时具有金属镜面效果及高透光性的视窗。
另外，还有必要提供一种应用上述视窗的电子装置。
一种视窗，其包括一透明基体，该视窗还包括形成于透明基体上的光透增强层及与光透增强层相结合的不导电金属层。
一种电子装置，其包括一本体及一视窗，所述本体设置有一显示器，该视窗盖设于本体的显示器上；所述视窗包括一透明基体，该视窗还包括形成于透明基体上的光透增强层及与光透增强层相结合的不导电金属层，所述显示器发出的光线依次经过该透明基体、该光透增强层及不导电金属层透射出来。
相较于现有技术，本发明视窗在透明基体上设置一不导电金属层，当所述电子装置在未使用状态时，该视窗的不导电金属层对光线具有高反射性，从而呈现出金属镜面效果，增强了视窗的外观性；当电子装置在使用状态时，所述视窗的不导电金属层又具有光穿透性，且通过光透增强层的设置来增强不导电金属层对光线的穿透，使人眼更易于阅读和观览资讯。且由于视窗的不导电金属层不导电，其对不会屏蔽电磁波，不影响电子装置的正常使用功能。    
附图说明
图1为本发明较佳实施方式视窗的剖视示意图。
具体实施方式
请参阅图1所示，本发明较佳实施方式的视窗10包括一基体11、形成于基体11上的底漆层13、结合于底漆层13上的光透增强层15、结合于光透增强层15上的不导电金属层17及涂覆于不导电金属层17上的面漆层19。
基体11为透明的塑料基体，其可以注塑成型的方式制成。注塑该基体11的塑料可选自为聚丙烯(PP)、聚酰胺(PA)、聚碳酸酯(PC)、聚对苯二甲酸乙二酯(PET)及聚甲基丙烯酸甲酯(PMMA)中的任一种。基体11亦可为玻璃基体。
底漆层13可为透明的紫外光固化漆膜，也可以为聚氨酯漆或不饱和聚酯漆等一般热固化漆膜。该底漆层13可增强光透增强层15与基体11的结合力及不导电金属层17的光亮度，其厚度可在6-12μm之间。
光透增强层15为二氧化硅或二氧化钛膜，其可以由真空蒸镀的方法制成。该光透增强层15的厚度可为50-100nm。当本发明视窗10应用于所述电子装置并在使用状态时，所述光透增强层15可增强电子装置的显示器所发出的光线对不导电金属层17的透过率，从而使人眼能够清晰的阅读和观览咨讯。
不导电金属层17为以真空蒸镀的方式形成的膜层。形成不导电金属层17的材料可选自铟、锡及铝硅等材料中的任意一种。该不导电金属层17具有金属质感外观，其厚度在50-150nm之间，由于不导电金属层17的不导电性，其对无线射频的传输或接收不会产生干扰(即不屏蔽电磁波或具有良好的电磁波穿透性能)。当本发明视窗10在未使用状态时，该不导电金属层17对外部光线具有较高的反射性，从而使其呈现出金属镜面的效果；而当视窗10在使用状态时，该不导电金属层17具有光线可穿透性。
所述光透增强层15、不导电金属层17的设置及其厚度的选择可通过光学膜系的数值计算软件计算出光谱曲线后而确定。
面漆层19为一透明的保护漆膜，其厚度可为8-15μm。该面漆层19可以为透明的紫外光固化漆，其具有较高的硬度以起到较好的表面保护作用。所述面漆层19中亦可添加彩色颜料，以使视窗10的外观更美观。
可以理解的，所述底漆层13可以省略，即光透增强层直接形成于透明基体11上。
可以理解的，当所述不导电金属层17具有较高硬度时，所述面漆层19亦可以省略。
本发明较佳实施方式的电子装置包括一本体及盖设于本体上的视窗10。所述本体上设置有一显示器，该视窗10盖设于本体的显示器上。所述视窗10包括一基体11、形成于基体11上的底漆层13、结合于底漆层13上的光透增强层15、结合于光透增强层15上的不导电金属层17及涂覆于不导电金属层17上的面漆层19。所述本体的显示器发出的光线依次经过视窗10的透明基体11、底漆层13、光透增强层15、不导电金属层17及面漆层19透射出来。所述本体可为手机、PDA、MP3或MP4的本体。
本发明较佳实施方式的视窗10在透明基体11上设置一不导电金属层17，当所述电子装置在未使用状态时，该视窗10的不导电金属层17对光线具有高反射性，从而呈现出金属镜面效果，增强了视窗10的外观性；当所述电子装置在使用状态时，所述视窗10的不导电金属层17又具有光穿透性，且通过光透增强层15的设置来增强不导电金属层17对电子装置的显示器所发出的光线的穿透，使人眼更易于阅读和观览资讯。且由于视窗10的不导电金属层17不导电，其对不会屏蔽电磁波，不影响电子装置的正常使用功能。
