從技術(shù)原理來(lái)區(qū)別觸摸屏，可分為五個(gè)基本種類(lèi)：矢量壓力傳感技術(shù)觸摸屏、電阻技術(shù)觸摸屏、電容技術(shù)觸摸屏、紅外線(xiàn)技術(shù)觸摸屏、表面聲波技術(shù)觸摸屏。其中矢量壓力傳感技術(shù)觸摸屏已退出歷史舞臺(tái)。觸摸屏紅外屏價(jià)格低廉，但其外框易碎，容易產(chǎn)生光干擾，曲面情況下失真；電容屏設(shè)計(jì)理論好，但其圖象失真問(wèn)題很難得到根本解決；電阻屏的定位準(zhǔn)確，但其價(jià)格頗高，且怕刮易損。表面聲波觸摸屏解決了以往觸摸屏的各種缺陷，清晰抗暴，適于各種場(chǎng)合，缺憾是屏表面的水滴、塵土?xí)褂|摸屏變的遲鈍，甚至不工作。按照觸摸屏的工作原理和傳輸信息的介質(zhì)，我們把觸摸屏分為四種，它們分別為電阻式、紅外線(xiàn)式、電容感應(yīng)式以及表面聲波式，下面筆者就對(duì)上述的各種類(lèi)型的觸摸屏進(jìn)行簡(jiǎn)要介紹：
