可选的,所述柔性基板41为柔性的TFT(Thin Film
Transistor,薄膜晶体管)阵列基板。
优选的,所述柔性基板41上设有薄膜封装层44。薄膜封装(Thin film
encapsulation,简称TFE),采用薄膜封装技术的柔性面板,在具有良好伸缩性能的同时,更轻、更薄。
可选的,所述触控面板42包括玻璃盖板、触摸感应膜层以及触控柔性线路板;所述触控柔性线路板嵌入所述触摸感应膜层,所述触摸感应膜层通过所述粘胶层43与所述柔性基板41连接。所述触摸感应膜层的结构可以为单层膜结构或双层膜结构。单层膜结构或双层膜结构为导电材料在绝缘膜层载体或者玻璃载体上生成的导电图案。导电图案通过激光镭射、蚀刻或曝光显影来实现。
本发明还提供了一种触摸装置,所述的触摸装置包括本发明所述的柔性触摸屏。采用本发明所述的柔性触摸屏的触摸装置,通过将触控柔性线路板整合到触控面板上,将触控面板的OLB制作在柔性基板上,实现触控面板的触控柔性线路板和柔性基板上相应的OLB区域可以直接进行绑定,从而减少一道FPC绑定制程,简化了柔性触摸屏FPC绑定制程且,减少了FPC的数量。
参考图7,本发明一实施例所述的柔性触摸屏的制作方法的流程图;所述方法包括如下步骤:S71:提供一柔性基板,并在所述柔性基板上沉积一层粘胶层;其中,所述柔性基板上设有主外引脚接合区以及触控引脚接合区。S72:提供一触控面板,所述触控面板与所述柔性基板通过所述粘胶层连接;其中,所述触控面板上与所述柔性基板相对的一面设有触控柔性线路板,所述触控柔性线路板的位置与所述触控引脚接合区的位置相对应。S73:在所述触控引脚接合区,将所述触控柔性线路板与所述触控引脚接合区上设置的柔性线路板绑定焊垫绑定连接,以及,在所述主外引脚接合区,将所述柔性基板通过所述主外引脚接合区上设置的柔性线路板绑定焊垫与主柔性线路板绑定连接。
以上所述仅是本发明的优选实施方式,应当指出,对于本技术领域的普通技术人员,在不脱离本发明原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本发明的保护范围。
