从技术原理来区别触摸屏,可分为五个基本种类:矢量压力传感技术触摸屏、电阻技术触摸屏、电容技术触摸屏、红外线技术触摸屏、表面声波技术触摸屏。其中矢量压力传感技术触摸屏已退出历史舞台;红外线技术触摸屏价格低廉,但其外框易碎,容易产生光干扰,曲面情况下失真;电容技术触摸屏设计构思合理,但其图像失真问题很难得到根本解决;电阻技术触摸屏的定位准确,但其价格颇高,且怕刮易损;表面声波触摸屏解决了以往触摸屏的各种缺陷,清晰不容易被损坏,适于各种场合,缺点是屏幕表面如果有水滴和尘土会使触摸屏变的迟钝,甚至不工作。
,看不太清楚,这就是清晰度太差。清晰度的问题主要是多层薄膜结构的触摸屏,由于薄膜层之间光反复反射折射而造成的,此外防眩型触摸屏由于表面磨砂也造成清晰度下降。清晰度不好,眼睛容易疲劳,对眼睛也有一定伤害,选购触摸屏时要注意判别。

1,386.83 1 PC RMB触摸屏是坐标系统,要选哪就直接点那,与鼠标这类相对定位系统的本质区别是一次到位的直观性。坐标系的特点是每一次定位坐标与上一次定位坐标没有关系,触摸屏在物理上是一套立的坐标定位系统,每次触摸的数据通过校准数据转为屏幕上的坐标,这样,就要求触摸屏这套坐标不管在什么情况下,同一点的输出数据是稳定的,如果不稳定,那么这触摸屏就不能坐标定位,点不准,这就是触摸屏怕的问题:漂移。技术原理上凡是不能同一点触摸每一次采样数据相同的触摸屏都免不了漂移这个问题,目前有漂移现象的只有电容触摸屏。
