Description

触控及指纹识别的装置 技术领域
本发明是有关于一种触控及指纹识别的装置，特别是有关于一种在指纹辨识区内能同时具有触控及指纹识别的显示装置。
 背景技术
传统的智能手机的触控模块与指纹识别模块是两个完全独立的模块。传统的基于电容式的指纹识别单元，通常是将指纹识别芯片设置于基板上，接着整合制成一指纹识别单元后再与触摸屏和其它装置结合。一般来说触摸屏设置在智能手机显示屏的上表面，而指纹识别模组设置在智能手机的非显示区域或者位于智能手机显示屏的下方。此外，传统的电容式触摸屏的触控电极分辨率只能感测触摸的位置，其无法实现电容式指纹辨别的要求，因此指纹识别需要单独更高分辨率的电容检测元器件。一般来说，当手指接触指纹识别单元的感测区时，由于芯片外面覆盖有多层膜，使得指纹识别芯片感应的灵敏度降低。因此，现有技术通常需要在智能手机上的玻璃保护盖板的底部另外制作通孔，来降低指纹识别芯片上方膜层的厚度，以使指纹芯片具有良好的感应能力。
 技术问题
传统的玻璃盖板的厚度约0.4毫米至1毫米，而传统的电容式指纹识别能穿透的厚度极限值约小于0.3毫米，因此传统的电容式指纹感应单元如果设置在保护盖板下方的触摸屏内部是无法满足要求指纹识别功能。故，有必要提供一种在指纹辨识区内能同时具有触控及指纹识别的显示装置，以解决现有技术所存在的问题。

 本发明的实施方式
本发明实施例公开一种触控及指纹识别的装置，包括显示模块、触控屏及设置在触控屏上的盖板。优选地，触控屏是柔性触控屏，触控屏包括导电材料，导电材料包括金属网、氧化铟锡(ITO)及银纳米线(silver nanowire)，以及触控屏设置在显示模块的上表面。优选地，盖板是塑料薄膜，例如聚酰亚胺薄膜(polyimide film)，盖板的厚度范围介于0.01微米至200微米之间，以及盖板的上表面涂布硬化层。相较于传统的玻璃盖板，传统的玻璃盖板的厚度约0.4毫米至1毫米，而传统的电容式指纹识别能穿透的厚度极限值约小于0.3毫米，因此传统的电容式指纹感应单元如果设置在保护盖板下方的触摸屏内部是无法实现指纹识别功能。
进一步而言，本发明实施例的触控屏包括设置在指纹识别区域外的至少一个第一触控电极，以及设置在指纹识别区域内的至少一个第二触控电极。具体地，至少一个第一触控电极包括至少一个第一驱动电极及至少一个第一感应电极，至少一个第二触控电极包括至少一个第二驱动电极及至少一个第二感应电极。
在本发明一实施例中，至少一个第一驱动电极及至少一个第一感应电极彼此垂直交叉设置在同一层上，且至少一个第一驱动电极及至少一个第一感应电极在同一层上的垂直交叉处彼此电性绝缘。优选地，至少一个第一触控电极的宽度范围介于约0.1毫米至约6毫米之间，彼此相邻的第一触控电极的间距范围介于0.05毫米至5毫米之间。
在本发明另一实施例中，至少一个第一驱动电极及至少一个第一感应电极彼此垂直交叉设置在不同层上，且至少一个第一驱动电极及至少一个第一感应电极在不同层上的垂直交叉处彼此电性绝缘。优选地，至少一个第一触控电极的宽度范围介于约0.1毫米至约6毫米之间，彼此相邻的第一触控电极的间距范围介于0.05毫米至5毫米之间。
在本发明一实施例中，在触控屏的指纹识别区域内，至少一个第二触控电极彼此相邻的间距范围介于5微米至50微米之间。优选地，至少一个第二触控电极彼此相邻的间距范围介于5微米至40微米之间。更优选地，至少一个第二触控电极彼此相邻的间距范围介于5微米至30微米之间。另外，第一触控电极和第二触控电极的形状包括方形、三角形、圆形、梯形或其组合。具体地，设置在指纹识别区域内的至少一个第二触控电极彼此相邻的间距范围介于5微米至50微米之间、5微米至40微米或介于5微米至30微米之间可以使指纹识别区域容纳更多的第二触控电极，进而达到指纹识别所需要的电容感应度。因此，触控屏的指纹识别区域的第二触控电极同时具有触控及指纹识别的功能。换言之，触控模块和指纹识别模块是一体成形设置在本发明实施例的触控屏内，当使用者触摸本发明实施例的触控屏的局部位置时，可以直接进行指纹辨别来解锁，且能同时进行其它操作，例如播放音乐。
参考图1，本发明实施例的触控及指纹识别的装置包括显示模块10、设置在显示模块10上的触控屏20及设置在触控屏20上的盖板30。
以下说明图2至图6，值得注意的是，图2至图6的指纹识别区域仅是作为例示性说明，指纹识别区域可以是触控屏的任意位置。
参考图2，在触控屏下端的指纹识别区域40，纵横交叉的单个直向第二触控电极42彼此之间的通道间距D1介于5微米至50微米之间。另外，单个横向第二触控电极44彼此之间的通道间距也是介于5微米至50微米之间。直向第二触控电极42的宽度W1和横向第二触控电极44的宽度也同样是介于5微米至50微米之间。
参考图3，在触控屏的中间位置的指纹识别区域40，纵横交叉的单个直向第二触控电极42彼此之间的通道间距D2介于5微米至50微米之间。另外，单个横向第二触控电极44彼此之间的通道间距也是介于5微米至50微米之间的。直向第二触控电极42的宽度W2和横向第二触控电极44的宽度也同样是介于5微米至50微米之间。
参考图4，在触控屏下端的指纹识别区域40，纵横交叉的多个直向第二触控电极42彼此之间的通道间距D3介于5微米至50微米之间。另外，多个横向第二触控电极彼此之间的通道间距也是介于5微米至50微米之间。直向第二触控电极42的宽度W3和横向第二触控电极的宽度也同样是介于5微米至50微米之间。
参考图5，在触控屏下端的指纹识别区域40，第二触控电极数量明显增加，通道宽度和间距较其余位置处明显较小，且纵横交叉的多个直向第二触控电极42彼此之间的通道间距间距D4介于5微米至50微米之间。另外，多个横向第二触控电极44彼此之间的通道间距也是介于5微米至50微米之间的。直向第二触控电极42的宽度W4和横向第二触控电极44的宽度也同样是介于5微米至50微米之间。
参考图6，在触控屏下端的指纹识别区域40，第二触控电与其余位置的第二触控电极彼此电性绝缘且通道宽度和间距较其余位置处明显较小。另外，纵横交叉的多个直向第二触控电极42彼此之间的通道间距D5介于5微米至50微米之间。多个横向第二触控电极44彼此之间的通道间距也是介于5微米至50微米之间。第二触控电极的宽度W5也同样是介于5微米至50微米之间。
综上述而言，本发明实施例提供一种触控及指纹识别的装置，触控模块和指纹识别模块是一体成形设置在触控屏内，使得触控屏同时具有触摸和指纹识别的功能，从而不需要再单独制作指纹识别模组，然后再镶嵌到显示模组内部，因此降低了成本。
虽然本发明结合其具体实施例而被描述，应该理解的是，许多替代、修改及变化对于那些本领域的技术人员将是显而易见的。因此，其意在包含落入所附权利要求书的范围内的所有替代、修改及变化。
