交互式触摸屏印度。当然，它比不上表面声波屏。电容屏有严重的反射。此外，电容技术的四层复合触摸屏对不同波长的光透射率不均匀，存在颜色失真的问题。由于光在层间的反射，图像字符被模糊。该电容屏的原理是将人体作为电容元件的电极。当一根导体接近夹芯ITO工作表面时，有足够的电容耦合，流动的电流足以导致电容屏故障。我们知道，电容值虽然与两极之间的距离成反比，但与相对面积成正比，也与介质的介电系数有关。因此，当手掌或手持式导体的大面积接近电容屏幕而不是触摸它，它可能导致电容屏幕发生故障。电容屏更重要的缺点是漂移:当环境温度、湿度变化时，环境电场变化会导致电容屏漂移，造成精度不高。由于没有原点，电容屏的漂移是累积的，经常需要在工作现场进行校准。 The outermost silicon protective glass of the capacitive touch screen has good scratch resistance. However, it is afraid that a small hole will hurt the sandwich ITO if it is struck by nails or hard objects. Whether it is the sandwich ITO or the damage during installation and transportation, The inner surface of the IT o layer, the capacitive screen can not work properly.
