摘要
为克服现有柔性触控装置分辨率较低及结构复杂等问题,应用电容式触控原理,开发了一种以单层非织碳膜为感应材料的柔性触控装置。测试表明,直角电极长度为72 mm的触控装置在126 mm×72 mm的工作区域内,X方向的线性度为!4.40%,Y方向的线性度为!4.39%;分辨率为251 dpi×243 dpi。为进一步讨论装置的触控精度,定义了偏移率。测试表明:偏移率在6%以上的感应点集中于工作区域边缘;增加电极长度有利于提高线性区域面积,但幅度不大。基于柔性与可携带性需求,选用点电极制作触控装置较优。
To overcome the problems such as low resolution and complicated structure that are associated with the existing touch control device,based on the capacitive touch principle a flexible touch control device is developed using a single-layer inductive non-woven carbon film as its touchpad.When a working area in the touch pad is set as 126 mm × 72 mm,with 72 mm side length of L-shape electrode,the test results show that the linearity of the touch control device in X and Y directions is ±4.40% and ±4.39%,respectively,and that the resolution reaches as high as 251 dpi × 243 dpi.For further discussion on the controlling accuracy of the device,the deviation rate is defined.The test results show that the control positions,of which the deviation rates are greater than 6%,are located near the edges of the working area.In addition,increasing the side length of the L-shape electrodes has positive but limited effects on the improvement of the linearity.Therefore,it would be preferable to use point electrodes for flexibility and wearablity.
