紅外觸摸屏的工(gong)作原理：

觸(chu)(chu)(chu)摸屏的四周布滿紅(hong)(hong)(hong)(hong)外(wai)(wai)接(jie)收(shou)管(guan)和(he)紅(hong)(hong)(hong)(hong)外(wai)(wai)發射(she)管(guan)，這(zhe)些(xie)紅(hong)(hong)(hong)(hong)外(wai)(wai)管(guan)在觸(chu)(chu)(chu)摸屏表面(mian)呈一一對(dui)應(ying)的排(pai)列關(guan)系，形成(cheng)一張由紅(hong)(hong)(hong)(hong)外(wai)(wai)線(xian)布成(cheng)的光網(wang)，當有物體(手指、帶手套(tao)或任何觸(chu)(chu)(chu)摸物體)進入紅(hong)(hong)(hong)(hong)外(wai)(wai)光網(wang)阻擋(dang)住某處的紅(hong)(hong)(hong)(hong)外(wai)(wai)線(xian)發射(she)接(jie)收(shou)時，此點橫(heng)豎兩個方向的接(jie)收(shou)管(guan)收(shou)到的紅(hong)(hong)(hong)(hong)外(wai)(wai)線(xian)的強弱就會(hui)發生(sheng)變化，設備通(tong)過(guo)了解紅(hong)(hong)(hong)(hong)外(wai)(wai)線(xian)的接(jie)收(shou)情況的變化就能知道何處進行了觸(chu)(chu)(chu)摸。紅(hong)(hong)(hong)(hong)外(wai)(wai)觸(chu)(chu)(chu)摸屏通(tong)過(guo)硬件(jian)設計(ji)和(he)軟(ruan)件(jian)編程，可以(yi)對(dui)各點數(shu)據進行插(cha)值計(ji)算，可以(yi)達(da)到32768 X 32768的分辨率。在紅(hong)(hong)(hong)(hong)外(wai)(wai)觸(chu)(chu)(chu)摸屏工作(zuo)時的同一瞬間，只(zhi)有一對(dui)紅(hong)(hong)(hong)(hong)外(wai)(wai)對(dui)管(guan) (指物理(li)位置(zhi)相對(dui)應(ying)的一只(zhi)發射(she)管(guan)和(he)一只(zhi)接(jie)收(shou)管(guan))在進行數(shu)據工作(zuo)，電路通(tong)過(guo)對(dui)紅(hong)(hong)(hong)(hong)外(wai)(wai)對(dui)管(guan)高頻率的數(shu)據采集來達(da)到迅速反(fan)應(ying)的效果，因此觸(chu)(chu)(chu)摸屏的反(fan)應(ying)速度非常(chang)快(kuai).

紅外線觸摸(mo)屏使用(yong)原(yuan)理(li)：

在(zai)(zai)顯(xian)示器(qi)上(shang)(shang)(shang)加上(shang)(shang)(shang)光點(dian)距架框(kuang)（紅(hong)外(wai)(wai)觸摸(mo)(mo)框(kuang)），無需在(zai)(zai)屏(ping)幕表(biao)面加上(shang)(shang)(shang)涂層或(huo)接駁控制(zhi)器(qi)。光點(dian)距架框(kuang)的(de)四邊(bian)排(pai)列了紅(hong)外(wai)(wai)線發射(she)管及(ji)接收管，在(zai)(zai)屏(ping)幕表(biao)面形成一(yi)個(ge)紅(hong)外(wai)(wai)線網(wang)。以(yi)手指觸摸(mo)(mo)屏(ping)幕某一(yi)點(dian)，便會擋住經過該位置的(de)橫豎兩條紅(hong)外(wai)(wai)線，計算機便可即(ji)時算出觸摸(mo)(mo)點(dian)位置。從而便可以(yi)代替了傳(chuan)統(tong)的(de)鼠標和鍵盤(pan)這樣的(de)外(wai)(wai)接設(she)備，直接在(zai)(zai)顯(xian)示器(qi)上(shang)(shang)(shang)用(yong)手指或(huo)者不透明名物體在(zai)(zai)顯(xian)示器(qi)上(shang)(shang)(shang)觸摸(mo)(mo)點(dian)擊任何操作(zuo)(zuo)(zuo)圖標，系統(tong)在(zai)(zai)接上(shang)(shang)(shang)觸摸(mo)(mo)設(she)備時會自動(dong)出現觸摸(mo)(mo)軟鍵盤(pan)，同樣可以(yi)在(zai)(zai)顯(xian)示桌(zhuo)面上(shang)(shang)(shang)使用(yong)軟鍵盤(pan)操作(zuo)(zuo)(zuo)，真(zhen)正意(yi)義上(shang)(shang)(shang)的(de)達(da)到(dao)(dao)了人機互動(dong)的(de)感念。觸摸(mo)(mo)屏(ping)的(de)出現也為(wei)不太(tai)習慣鼠標及(ji)鍵盤(pan)的(de)使用(yong)者帶來了方(fang)便，可以(yi)直接在(zai)(zai)電腦桌(zhuo)面上(shang)(shang)(shang)手寫。隨(sui)著時代的(de)發展，紅(hong)外(wai)(wai)觸摸(mo)(mo)屏(ping)可以(yi)實現多(duo)點(dian)操作(zuo)(zuo)(zuo)及(ji)支持多(duo)人操作(zuo)(zuo)(zuo)，這是傳(chuan)統(tong)的(de)鼠標不能達(da)到(dao)(dao)的(de)領域。
