所述柔性基板12可采用柔性印刷电路板(Flexible Printed Circuit, FPC)。所述第一蓝光LED组14与所述第二蓝光LED组15分别由多个以预定间距排列的蓝光LED组成,所述预定间距可设计为相邻的蓝光LED之间具有相同的间距或是不同的间距,以配合不同产品的应用需求。若所述预定间距设计为相邻的蓝光LED之间具有不同的间距,这些不同的间距可为至少2种或2种以上。所述第一蓝光LED组14与所述第二蓝光LED组15分别设置于所述柔性基板12的两个相背对的表面上,并且所述第一蓝光LED组14与所述第二蓝光LED组15中的每个蓝光LED皆与所述柔性基板12电连接。所述柔性基板12可采用不透光的材料制成,以避免两个柔性LCD面板所显示的画面互相影响。
在所述第一蓝光LED组14与所述第二蓝光LED组15上,分别设置所述第一黄色荧光粉层16与第二黄色荧光粉层17,当所述第一蓝光LED组14中的蓝光LED发光时,会激发所述第一黄色荧光粉层16进而发出合成的白色光做为所述第一柔性LCD面板30的背光源。同样地,所述第二蓝光LED组15与所述第二黄色荧光粉层17配合亦会发出合成的白色光做为所述第二柔性LCD面板50的背光源。所述第一黄色荧光粉层16与所述第二黄色荧光粉层17可以选择性直接设置在所述第一蓝光LED组14与所述第二蓝光LED组15的一个或多个蓝光LED上,同样可达到蓝光LED发光时激发黄色荧光粉层发出白色光的效果。
在所述柔性基板12的所述第一黄色荧光粉层16的一侧,所述第一柔性LCD面板30通过第一固着材料22贴附在第一黄色荧光粉层16上,以与所述柔性基板12结合。在所述柔性基板12的所述第二黄色荧光粉层17的一侧,所述第二柔性LCD面板50通过第二固着材料24贴附在第二黄色荧光粉层17上,以与所述柔性基板12结合。所述第一固着材料22与所述第二固着材料24可以是发泡胶带(Foam Tape)材料或者其他类似的固着材料。若所述第一黄色荧光粉层16与所述第二黄色荧光粉层17是采用直接设置在所述第一蓝光LED组14与所述第二蓝光LED组15的一个或多个蓝光LED上的技术方案,则所述第一固着材料22与所述第二固着材料24可以直接贴附在所述柔性基板12的边缘处,以达到使所述第一柔性LCD面板30及所述第二柔性LCD面板50通过所述第一固着材料22及第二固着材料24与所述柔性基板12结合固着的效果。
在所述第一柔性LCD面板30上,从与所述第一黄色荧光粉层16接合的一侧以远离所述柔性基板12的方向依序排列为第一下偏光片38、第一薄膜晶体管(Thin Film Transistor, TFT)层32、第一彩色滤光片34及第一上偏光片36。在所述第二柔性LCD面板50上,从与所述第二黄色荧光粉层17接合的一侧以远离所述柔性基板12的方向依序排列为第二下偏光片58、第二薄膜晶体管(TFT)层52、第二彩色滤光片54及第二上偏光片56。所述第一柔性LCD面板30的第一上偏光片36、第一彩色滤光片34、第一TFT层32及第一下偏光片38是采用柔性材料制成,例如聚酰亚胺(Polyimide,PI)材料。同样的,所述第二柔性LCD面板50的第二上偏光片56、第二彩色滤光片54、第二TFT层52及第二下偏光片58也是采用柔性材料制成。
本揭示实施例所提供的可双面显示的柔性液晶显示模块具有相背对的两个柔性显示面板,每个柔性显示面板可以被控制在同一时间内显示相同或不同的画面,并且柔性液晶显示模块的设计可以适应不同的使用需求与情境,使可双面显示的柔性液晶显示模块的使用场景更为广泛,提高了产品的用户体验,进而增加了产品的市场竞争力。
综上所述,虽然本揭示已以优选实施例揭露如上,但上述优选实施例并非用以限制本发明,本领域的普通技术人员,在不脱离本揭示的精神和范围内,所衍生的各种更动与变化,皆涵盖于本发明以权利要求界定的保护范围内。
