Description

一种手写液晶膜及手写装置 技术领域
本申请涉及手写液晶膜技术领域。
背景技术
随着科技的进步发展，手写液晶装置应用的场景越来越广泛。传统的手写液晶膜一般依次设置有第一基体层、第一导电层、液晶层、第二导电层、第二基体层、基底。手写液晶膜的原理是：利用胆甾相液晶的双稳态特性，当胆甾相液晶分子排列为P态时，反射光入射光，此时，如果基底是黑色的话，观察到的就是黑底上显示字迹，字迹的颜色由反射光的波长决定；当液晶分子排列为Fc态时，散射入射光，此时观察到的基底的颜色，即黑色。由于传统的手写液晶膜的基底的颜色是单色的，所以手写液晶膜的笔迹颜色也只能是单色的，并且笔迹的颜色是不能够进行调节的。
虽然目前市场上有些手写液晶膜能够做到多种颜色的笔迹或者彩色的笔迹，但是这种手写液晶膜普遍是不同区域不同颜色，同一个点不能切换不同颜色。也就是，用户想在已有的手写笔迹上做不同颜色标记时，无法实现。另外，如果整体的结构是使用多张不同颜色手写液晶膜叠加到一起，然后通过分别控制多张手写液晶膜去控制笔迹的颜色。这种手写液晶膜的缺点比较明显，首先就是手写膜的厚度比较大，制造成本较高；其次就是笔迹的显示效果不够好，亮度不够清晰，在最上层的膜会影响到底层膜的笔迹显示效果。
技术解决方案
本申请的主要目的是提出一种手写液晶膜及使用该手写液晶膜的手写装置，本申请提出的手写液晶膜内部能够设置两个液晶层以上，通过分开控制液晶层能够实现多种颜色的笔迹。
本申请实施例第一方面提供一种手写液晶膜，包括：
至少一个中间基体，所述中间基体的上下两面均设有中间导电层；
第一基体，所述第一基体上设有第一导电层；
第二基体，所述第二基体上设有第二导电层，所述中间基体位于所述第一导电层和所述第二导电层之间；
基底，所述基底贴合固定在所述第一基体或所述第二基体的外侧表面上；
至少两个液晶层，所述第一导电层和其中一个所述中间导电层之间设有一个所述液晶层，所述第二导电层和另一个所述中间导电层之间也设一个所述液晶层。
本申请实施例第二方面提供一种手写装置，包括前述各实施例所记载所述的手写液晶膜。
本申请实施例所提供的手写液晶膜内设中间基体，中间基体的两侧设置中间导电层，两个中间导电层再分别与第一导电层、第二导电层进行组合，在中间导电层与第一导电层、另一个中间导电层与第二导电层之间都设置有液晶层，这样中间基体的上下两侧都设置有液晶层，整个手写液晶膜便拥有了两个液晶层，通过两个液晶层和基底的组合，可以在手写液晶膜上显示多种笔迹颜色。使用中间基体当做内部两个液晶层的基体，相对于传统的手写膜能够节省一层基体，相对于多张手写膜叠加形成的多颜色笔迹的手写膜来说，本申请的手写液晶膜厚度更小，结构更加简单稳定，制造成本较低。

请参考图3，在实施例1的基础上提出了一种手写液晶膜，包括：一个中间基体400，所述中间基体400的上下两面均设有中间导电层500；第一基体100，所述第一基体100上设有第一导电层200；第二基体700，所述第二基体700上设有第二导电层600，所述中间基体400位于所述第一导电层200和所述第二导电层600之间；基底800，所述基底800贴合固定在所述第二基体700的外侧表面上；两个液晶层300，所述第一导电层200和其中一个所述中间导电层500之间设有一个所述液晶层300，所述第二导电层600和另一个所述中间导电层500之间也设一个所述液晶层300。所述中间基体400为双层式基体层。
本实施例与实施例1对比，不同之处在于所述中间基体400层为双层式基体层，所述中间基体400使用两张PET膜通过OCA光学胶900粘贴固定到一起，然后再在两张PET膜上相对的位置上设有所述中间导电层500。
应当说明的是，本申请的各个实施例的技术方案可以相互结合，但是必须是以本领域的技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当人认为这种技术方案的结合不存在，也不在本申请要求的保护范围之内。
以上所述仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
