Description

一种应用于手持终端设备的复合镜片
【技术领域】
本发明涉及手持终端镜片的技术领域，具体是涉及一种应用于手持终端设备的复合镜片。
【背景技术】
手持终端（如对讲机、PDA、POS机等）的发展趋势是体积更小、厚度更薄、质量更轻，同时抗跌落、耐冲击的可靠性要求也越来越高。镜片作为手持终端显示屏的外部防护装置，其要求也是越来越薄，同时还需满足跌落和冲击等可靠性要求。
目前用于手持终端的镜片为树脂板材镜片和钢化玻璃镜片：
树脂板材镜片：材料为PMMA或者PMMA+PC，具有良好的抗跌落和抗冲击性能。但材质较软，厚度要做到1.5mm以上才能不会受压变形压到液晶显示屏。（液晶屏按压会出现色彩失真）。
钢化玻璃镜片：材料为钢化玻璃（化学钢化处理），具有良好的强度和表面硬度。由于化学钢化的不稳定性，即便是康宁的钢化玻璃，仍有一定比率出现跌落破碎的现象。
【发明内容】
本发明实施例提供一种复合镜片，以解决现有技术中普通镜片不能兼顾轻薄、硬度高以及抗冲击能力强的技术问题。
为解决上述问题，本发明实施例提供了一种应用于手持终端设备的复合镜片，所述复合镜片包括层叠设置的树脂层和钢化玻璃层，其中所述复合镜片安装于所述手持终端设备时，所述树脂层位于外表面，所述钢化玻璃层位于内表面。
根据本发明一优选实施例，所述复合镜片还包括设于所述树脂层和所述钢化玻璃层之间用于粘接所述树脂层和所述钢化玻璃层的光学胶层。
根据本发明一优选实施例，所述复合镜片进一步包括设于所述光学胶层与所述树脂层之间或者所述光学胶层与所述钢化玻璃层之间的丝印油墨层，所述丝印油墨层用于丝印标识或者边框。
根据本发明一优选实施例，所述丝印油墨层环状夹设于复合镜片的内部环周或者条状夹设分布于复合镜片的内部。
根据本发明一优选实施例，所述树脂层的厚度为0.3-0.8mm。
根据本发明一优选实施例，所述丝印油墨层的厚度为0.02-0.10 mm。
根据本发明一优选实施例，所述钢化玻璃层的厚度为0.3-1mm。
根据本发明一优选实施例，所述光学胶层的厚度为0.05-0.2mm。
根据本发明一优选实施例，所述树脂层的非粘接侧硬化处理，处理后硬度大于3H。
本发明实施例提供的复合镜片应用于手持终端设备，包括对讲机、私人数码终端、POS机。
相对于现有技术，本发明提供的复合镜片，将树脂层与钢化玻璃层利用光学胶粘接在一起，使该复合镜片在满足轻薄的情况下，还同时具备了钢化玻璃的强度和硬度以及树脂材质的柔性和抗冲击性的特点，另外，该复合镜片安装于手持终端设备使用时，树脂层位于外表面，而钢化玻璃层位于内表面。该种设置的优势为将树脂层位于外表面可以吸收跌落和冲击的能量，而将钢化玻璃层设于内表面则可以提高复合镜片的抵抗形变和强度性能。
【附图说明】
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是本发明复合镜片一优选实施例的结构示意图；以及
图2是本发明复合镜片另一优选实施例的结构示意图；以及
图3是本发明复合镜片应用于手持终端设备的结构示意图。
【具体实施方式】
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
请参阅图1，图1为本发明复合镜片一优选实施例的结构示意图，该复合镜片包括相互层叠设置在一起的树脂层110和钢化玻璃层120，其中该复合镜片安装于手持终端设备使用时，该树脂层110位于外表面，该钢化玻璃层120位于内表面。该种设置的优势为将树脂层110位于外表面可以吸收跌落和冲击的能量，而将钢化玻璃层120设于内表面则可以提高复合镜片的抵抗形变和强度性能。
具体而言，该树脂层110的厚度可以设置为0.3-0.8mm之间，譬如0.5mm，钢化玻璃层120的厚度可以为0.3-1mm，其中，该树脂层110厚度和钢化玻璃层130厚度值可以根据设备的抗冲击强度以及表面硬度等的要求具体设置，在本领域技术人员能够理解的范围之内，此处不再一一列举。
优选地，该复合镜片还包括设于树脂层110和钢化玻璃层120之间用于粘接树脂层110和钢化玻璃层120的光学胶层130（OCA（Optically Clear Adhesive）用于胶结透明光学元件（如镜头等）的特种粘胶剂。其具有无色透明、光透过率在90%以上、胶结强度良好，可在室温或中温下固化，且有固化收缩小等特点）。该光学胶层130的厚度一般为0.05-0.2mm。
另外，树脂层110的非粘接侧还可以做硬化处理，使处理后的硬度大于3H，防止使用过程中表面容易被刮花。
本发明实施例提供的复合镜片通过将树脂层与钢化玻璃层利用光学胶粘接在一起，使该复合镜片在满足轻薄的情况下，还同时具备了钢化玻璃的强度和硬度以及树脂材质的柔性和抗冲击性的特点。
请参阅图2，图2是本发明复合镜片另一优选实施例的结构示意图，该复合镜片包括树脂层210、钢化玻璃层220、设于树脂层210与钢化玻璃层220之间的光学胶层230之外，还包括丝印油墨层240。
该树脂层210的厚度同样可以设置为0.3-0.8mm之间，譬如0.5mm，树脂层210的非粘接侧还可以做硬化处理，使处理后的硬度大于3H，防止使用过程表面很容易被刮花。钢化玻璃层220的厚度可以为0.3-1mm；光学胶层230则设于树脂层210和钢化玻璃层220之间用于粘接树脂层210和钢化玻璃层220，该光学胶层230的厚度一般为0.05-0.2mm。
丝印油墨层240则可以设于光学胶层230与树脂层210之间或者光学胶层230与钢化玻璃层220之间，其中，图2中只给出了丝印油墨层240设在光学胶层230与树脂层210之间实施例。该丝印油墨层240用于丝印标识或者边框，边框的作用是遮住粘贴镜片的面壳台阶，以提高美观度；丝印油墨层240的厚度很小，大概为0.02-0.10mm，或者可以忽略不计。其中，丝印油墨层240可以环状夹设于复合镜片的内部环周，还可以以条状或者片状夹设分布于复合镜片的内部，针对不同的美观设计要求做不同布置，此处不再赘述。
该实施例中的复合镜片，在具备上一实施例中复合镜片的轻薄、柔性好、强度和硬度高以及抗冲击性能强等优点的同时，还在其内部还夹设有丝印油墨层，用于丝印标识或者边框，以增加美观度。
本实施例提供的复合镜片主要应用于手持终端设备，请参阅图3，图3是本发明复合镜片应用于手持终端设备的结构示意图，从图中可以看出，树脂层210（或110）位于该手持终端设备的外表面。其中，该手持终端设备可以包括对讲机、私人数码终端（PDA）、POS机等。关于手持终端设备其他部分结构特征在本领域技术人员能够理解的范围之内，此处不再赘述。
以上所述仅为本发明的一种实施例，并非因此限制本发明的保护范围，凡是利用本发明说明书及附图内容所作的等效装置或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
