PP845A红外线式触摸屏特点
PP845A红外式触摸屏不受电流、电压和静电干扰,适合某些恶劣的环境条件。其主要优点是价格低廉,安装方便,不要卡或任何其他控制器,可以用在各种档次上的计算机。
PP845A此外,由于没有电容充放电过程,响应速度比电容式快,但分辨率较低。
PP845A电阻式触摸屏
PP845A电阻屏·外层一般使用的是软屏,通过按压使内触点上下相连。内层装有物理材料氧化金属,即N型氧化物半导体——氧化铟锡(IndiumTinOxides,ITO),也叫氧化铟,透光率为80%,上下各一层,中间隔开。
PP845AITO是电阻触摸屏及电容触摸屏都用到的主要材料,它们的工作面就是ITO涂层,用指尖或任何物体按压外层,使表面膜内凹变形,让内两层ITO相碰导电从而定位到按压点的坐标来实现操控。根据屏的引出线数,又分有4线、5线及多线。
PP845A一般是不能多点触控,即只能支持单点,若同时按压两个或两个以上的触点,是不能被识别和找到·确坐标的。在电阻屏上要将一幅图片放大,就只能多次点击“+”,使图片逐步进阶式放大,这就是电阻屏的基本技术原理。
